What/How quick reboot works? On my Android 4.2.2 (Micromax Canvas A74), From System settings >Accessibility, there is option for enabling  "Quick Reboot" as follows:

Screenshot (click image for larger variant)

So How it differs from normal reboot? Or what enabling this exactly work?

I've never seen this option built-in, but there are several apps/widgets on the Playstore offering a "quick boot" as well. The term is a little misleading, as it's usually not a boot at all.

For some background information, let me first refer to my answer on Can somebody explain the boot process of an Android device?. Quick-reboot usually kills everything down to the "system server", so Zygote has to start it anew. As Zygote is the parent to all apps, basically the "Android-part" of the system is completely reloaded – while the underlying "Linux-part" keeps running.

From the users' point of view, this looks like a "quick reboot": the graphical interface (all apps, including the home screen) disappear, and then the system comes up again exactly like after a "boot". But during this process, the first 4 steps of a "real boot" (as outlined in the linked question) were skipped.

I'm not 100% sure if the "quick boot" option you are seeing there is the same, but it's pretty likely. Because, if it were a "full boot, just quicker" – then why shouldn't that be used in the first place?

I have two Blu Phone, the Dash 5.0 with 4.4.2, and a 5.0 HD also 4.4.2. The build numbers are different though. The HD has the quick boot option. The Dash does not. Before I enabled the quick boot the boots times were the same about 35 secs. But now with it enabled, the HD boots in 14 seconds. So it does what it says and does not seem to work any differently after booting.

Wifi password lost every time I reboot my phone VS985 - Verizon LG G3 - CM12 Nightly - 5.0.2

This has been going on for a few months now, and is just driving me bonkers. Every time I reboot my phone, and am home, my phone forgets the password for the wifi. All other devices in the house (iphone, ipad, laptops, kindles, chromecasts, etc.) do not have this issue.

This only happens for my home router – passwords for other networks are surviving reboots.

As I have my phone how I like it, I don't want to start from scratch. I tried wiping system, but it's like the password is a part of my personal data and that for some reason it is forgotten so often? Does anyone have ideas on how I could go about fixing this?

Not a solution, but a work-around:

The WiFi password is not stored on /system – it's in /data/misc/wifi/wpa_supplicant.conf. As you're using CyanogenMod, it should be safe to assume you're having root access. So you could use an automation tool (yes, I've got tasker in mind here) to copy that file to a "safe place" whenever shutting down the device, and have it restored from there on each boot.

I have changed permissions to 644 (from 660) on /data/misc/wifi/wpa_supplicant.conf. That helped (so it seems so far).


Which devices can run xmod coc? I have zenfone 2. The guy that root my phone told me that I cannot run xmod coc there because zenfone 2 uses intell.

How do we know which devices xmod support?

Note: I tried and it didn't work.

I got that oops mod not working now

Also I already checked

http://m.xmodgames.com/faq/72.html

I am not sure if it's up to date. It says it doesn't support bluestack. Yet I've heard people playing coc with xmod with bluestack. It didn't work on my bluestack.

I am going to try xiaomi.

Zenfone devices have intel cpu. If you can root your phone so you can use xmod ,check your device support in xmod website!


Galaxy Nexus won't connect via USB So my Galaxy Nexus has been fine until now. It has been running Android 4.2 and it was going perfect, then like a day ago I go to plug it in and it just won't connect via USB. It charges on USB but that's it. The drivers are installed and the problem is not my computer; I tried it on another computer as well, I haven't changed anything at all. The last option I think for me is to do a factory reset, which I reaaally don't want to do.

It won't even come up with USB connected on the phone.

Any ideas?

UPDATE

I sent mine back for repairs and the mobo was screwed on it. No idea what caused it.

Funny thing is: Blowing into the phones USB solved the problem for me. Maybe you try that =D

Check this out. Don't do a factory reset yet because the problem probably has something to do with the cable not the phone. This seems to be a relatively known problem. look at this Google search.


"Slide to answer" alternative on Lollipop I'm using ZTE Maven running Android 5.1 Lollipop, and while there are 3 physical buttons on the front of the phone beneath the display, by default to answer a call you have to touch a green virtual button on the display and "slide to answer".

I get calls very infrequently and when I do I have a lot of difficulty answering calls.  At first I concluded that I have to hold on the green virtual button until it activates, and then slide it, but recently that doesn't work either and I end up missing the call.

I understand there are apps for changing this behavior, but I'd prefer a configuration solution.  I think once I found a mention of an accessibility setting for this, but the only documentation I can now find is for pre-Lollipop versions of Android and it doesn't seem to apply.

Is there a way to configure Lollipop with an alternative way to answer calls?

If you're using Samsung Galaxy S-series, you can change the call answering and ending options in Settings > Accessibility > More settings > Answering and Ending calls. I didn't like the way it worked, I now have it set up so all I press is the home key.

The other one is Single tap mode, which is like its name, answering/rejecting incoming calls with a single tap.

Swipe once, then tap blue phone symbol once.


Always seeing "No connection: Retry" in Android Market I have an HTC Touch with Froyo installed that I use for app development. I haven't used it for a couple of months, and when I fired it up today I'm seeing the same error every time I launch the Market app: No connection and a Retry button. It doesn't matter how many times I hit Retry, I just end up back in the same place. The phone definitely has a solid Wi-Fi connection though and all other online apps (browser, Twitter, etc.) are working well.

I've tried force stopping the Market and restarting, clearing its data and uninstalling updates, all to no avail. What can be causing this error?

The answer is that the date/time settings were incorrect. The device had been off for so long that the clock had reset. Once I set the correct date and time the Market app ran normally.

Try clearing cache and data for the Market app. You can do this by going to menu>settings>applications>manage applications>all and scrolling down to the Market app then using the "clear data" and "clear cache" buttons.


Get offline maps in new Google Maps Google Maps was updated last night (9-July-2013 v7.0.0). While there's a lot they added, one thing they removed was the ability to cache maps offline.

I relied on that functionality in poor-coverage areas. Is there anything I can do?

Open Google Maps and search for the area you want to cache (or just zoom in on it).

Tap the search bar.
Type "Okay Maps" (some people report success with just "OK Maps") in the search bar.
Tap the search icon

You'll be dropped back at the maps view, and you'll see a notification that the area was copied to your clipboard or otherwise cached. Now, even offline you'll still be able to zoom down to the same level you were at on that map area.

You might want to take a look at little helpers like e.g. MapsOn Free: Offline Map:

  Offline GPS travel maps. Cache maps to SD card and use them when traveling without network coverage.

This one fills GMaps' map cache (at least it did before it was renamed; the current screenshots confuse me a little concerning whether that was changed, but it's certainly worth a try with the free version; if that works out, you can still decide whether to "go pro").


How to flash a ZIP file with Odin? I can't boot my Galaxy Tab 8.9 / P7300 anymore, but Odin still detects a USB connection. So I'm trying to flash a new ROM onto it using Odin. However all I can find on the web are ZIP archives containing boot.img, META-INF etc, while Odin apparently needs .tar or .tar.md5 files.

Can I convert one into the other, or is my idea completely wrong?

.zip files are generally flashable from recovery, Odin's .tars are indeed a completely different format.  If flashing a kernel you can convert them relatively easily (thought I won't get into it here) but it won't work for a whole ROM.  You'll need to find an Odin package.  XDA is your best bet, but see also: Where can I find stock or custom ROMs for my Android device?

Anyone reading this that is also late to the discussion: If you found the Zipped Rom in question on XDA, it was probably originally a tar file that someone renamed zip in order to use a file hosting website with a restriction against tar files. (As this simple rename just worked for me.)


Seeking alternative to Andoid File Transfer utility Need usb alternative to Android File Transfer for Mac. Problems: 1. no search capability 2. Cannot report size of files. 3. No route to send problem reports to developer. Reasons for not using bluetooth: security.

You can use adb push/pull, it is command line based but working well. You can search using an adb shell.


How to install recovery after rooting Xperia M (stock ROM 4.3) to install custom ROM? I have a rooted Xperia M Dual (C2004) with stock ROM 15.5.A.1.5 (4.3 Jelly Bean). Bootloader unlocking is allowed and I also have the unlock code already.

Since Sony decided to stop giving updates I wanted to install a custom ROM. So went ahead and rooted it but now I'm stuck.
I am still on stock ROM because I don't know how to proceed now.

Some threads say to unlock bootloader and flash the ROM, some say to flash the stock ROM first then recovery.

I found this app called TWRP Manager on my device's twrp page( https://twrp.me/devices/sonyxperiam.html ) which has an option to install TWRP.
But since my bootloader is still locked I don't know if it's safe.

A guide on XDA has instructions but it says after unlocking bootloader flash the custom ROM which is a huge 700 megabytes download and I at the moment don't have the bandwidth.

So is it possible for me to install TWRP via that app and flash the custom ROM directly?
Or what else should I do?

You have to unlock your bootloader to fiddle around with your phone. Without unlocking you really CANNOT do anything. Unlocking bootloader is straight. You won't mess up anything there. It's the installing of custom recovery which will bug you. Careful.


Is it possible to override automatic screen orientation? Very often I use my phone lying in bed (with phone camera facing the ceiling) and the orientation changes drive me crazy. Literally if I turn the phone a few degrees it will go from portait to landscape and vice versa.

I can disable auto-rotation, but it's not desirable in some scenarios, like when i turn on my shoulder and I want the orientation to change.

Basically, is it possible to write your own logic for screen rotation and make it run on system wide scope?

UPD: I do not want to toggle auto-rotation. I want to rewrite that logic that based on current sensor setting changes the screen orientation on system level.

This widget works well... No customer rom or root required. :0)

In CyanogenMod, and you can set up to have the power widget on the notification bar, the power widget in Cyanogen is enhanced so it can control more settings, one of it is the ability to lock the orientation sensor. Whenever you want to lock, simply pull out the notification bar and tap on the lock orientation button.


Moto G 1st Gen - Mobile Data not working after upgrade to 5.0.2 After upgrading to Lollipop from 4.4.4, mobile data doesn't work. I have tried all the solutions listed in various forums including,
1. Reboot
2. Reboot after re-inserting the sim card.
3. Manually add the APN (Got the settings from the service provider)
4. Toggle between the Preferred Network type (2G and 3G)

I have only one usable sim slot, and so cannot use sim slot-1. I have heard it worked for a few guys after putting the sim in the other slot, but unfortunately I cannot try that out.

Any suggestions?

Okay, so here I am posting an answer to my own question.
I finally visited a Motorola service center today to get the problem fixed and I was told that they are aware of the issue and that they'll be rolling out an update with a fix in 5 days.
Hopefully everything will turn out well after that.


Accidentally Deleted Voice-to-Text app for Samsung Galaxy SIII I was running out of memory on my phone, and so went through all my apps and deleted those I didn't use to create more room....apparently, by doing so, I deleted the app that lets me voice-to-text on text messages or even search by voice in google chrome.

Can someone help me fix this without resetting my phone to factory settings???

Not to wake an old thread but I was looking for the solution to this same problem and wasn't finding a solution. I had disabled my Google  app , turning it back on fixed my issue. Settings,applications,all and find "google app"

You can download it from the Samsung Store in your Phone. Otherwise you can download Google text to speech in the PlayStore


Unable to download apps from Play Store using mobile data I have Mi4i mobile. I am trying to download  applications from Google Play Store- when I click on Install it  displays  "Waiting for WIFI...".

I am on mobile data, but it is not downloading through mobile data.

How can I download through mobile data?

For MIUI 8(previous versions also).
Check your 'Security' app's -> Data usage -> Restrict data usage -> System tab. Within system check Downloads is allowed to use Mobile data.

You may need to clear all data of Google Play store. I always prefer not to download from play store due to slow connection. There are many site which allow me to download apk file. See What are the alternative app markets? for more details.


Connect Android phone to router via USB-to-Ethernet I own an HTC Desire HD and it currently has the IceColdSandwich custom rom on it. I also own a usb OTG adapter and a D-Link USB 2.0 Fast Ethernet adapter DUB-E100.

What I want to achieve is to connect my phone on a Cisco Router with that "cable sequence"(Phone -> USB OTG adapter -> USBtoETHERNET dub-e100 -> ethernet cable -> Router) and be able to sustain a telnet connection between the two in order to give network configuration.

In order for this to work I definitely need to enable the USB host mode on my device through kernel.

Let's say I can get my kernel to work do I need the usbnet driver with my combined hardware for the dub-e100 to work? or maybe there is really no way for this to be done?

any ideas on alternative ways to do this?

-edit-
There are many reasons why one would want to do this. For example, testing an ethernet port in an office building without having to lug around a laptop. Another, be able to configure a router that does not have wireless, or one that you can't access the wireless on (maybe you butterfingered the encryption key on the AP)
-edit- by Izzy

Check out the App Ethernet on Google Play. You will need to root your phone though.


Unplugged my cable while upgrading via Odin My cable was unplugged while my Samsung Galaxy S2 I9100 upgrading with Odin. Now, nothing appears on the screen, even when I plug the charger. How can I fix my device?

You will have to Switch ON the phone in "Safe Mode" by pressing the Volume down, Power, and the Home button all together. Then, factory reset the phone, and upgrade it through Odin; or on a safer side, use Samsung Kies for upgrading to a new OS.


Merging duplicate contacts - is my phone broken? I just got my Samsung Galaxy S3 (Android 4.1.1) and I'm having the usual trouble with ridiculous amounts of duplicate contacts. I've tried the following methods to no avail:

My mom told me to go to Contacts, and click "Merge with Google" in the menu. It had me add a Google account and was able to remove some of the duplicates, but many still have 5-6 for a single contact. My mom said the whole thing would be ruined if I repeated the process.
I've been checking online, and I found similar questions here where the answer boils down to clicking "Find & Merge Duplicates..." on contacts.google.com. I tried it, and it claimed to merge four contacts. I still have many duplicates.
I tried to manually join some contacts a couple of ways:

Go to Contacts, click the contact to open more details, click the link icon under the Connection heading, tap "Join another contact," select another contact
Go to Contacts, click the contact to open more details, open the menu, select "Join contact," select another contact
Go to Contact, press and hold the contact, select "Join contact," select another contact
Go to Contacts, click the contact to open more details, open the menu, select "Edit," click the menu key

For the first three methods, the phone flashed a message that said "Contacts joined." The contacts were not joined. The last one would not allow me to open the menu.

Is there another method that I'm supposed to use to merge my contacts? Did I do one of the above methods wrong?

I worry that my beautiful new phone is broken because joining contacts didn't work and it refuses to sync contacts with my google account :(

You could perhaps try the same method from within the Gmail interface.

From within Gmail, navigate to contacts.
From the menu More, click on Find & Merge Duplicates.


Why does Android prompt me with "Enter the credential storage password" when I attempt to connect to a secured WiFi network? When I connect my iPhone to a secured WiFi network (at work), I'm prompted for my Username and Password. (And then I'm prompted to accept what I presume is an SSL certificate.)

But when I select the same network on my Motorola Droid or HTC EVO 4G, I'm prompted with "Enter the credential storage password".  What is this password?

I went into Settings -> Location & Security (on Droid, Security on the EVO) -> Use secure credentials, and entered the credential storage password.  Then I was no longer prompted for this password when selecting the WiFi network.

Go to your Settings
Select Security
And Set a 4 digit pin.

It worked for me.


Constant " Download unsuccessful." notifications I'm constantly harassed by these "<Untitled> Download unsuccessful." notifications.

After taking the above screenshot, I cleared the entire notifications list. Within the next three minutes (usually even less), the list was already overflowing again.

I've learned to manage the symptom by navigating to the Download Manager application settings; hitting FORCE STOP, followed by CLEAR DATA, and CLEAR CACHE. Although the notifications slowly start showing up again. Just one at first, but gradually increasing in number with each occurance. Within a day or two, the numbers are usually back out of control.

I have no idea what it's supposedly attempting to download, or why. But whatever it is, it's not instigated by myself. I could just disable download notifications, but I'd rather identify the underlying problem and kill it directly. Needless to say, I'm not too keen on my devices automatically trying to download random mystery files from the internet. Any ideas? Thanks.

FYI: The device in question is a ZTE Blade L5 smartphone.

I think I solved my issue with constant "download unsuccessful" notifications. In the Puffin browser I went to settings and the download icon then erased all. Haven't seen an instance for quite awhile.

I have had this problem with the ZTE BLADE and found that if you go into Settings › Notifications › Downloads, then block the Downloads, it should stop the notifications after you clear them a couple of times. It worked for me.


Mobile data in notification toggle I upgraded my Moto G 2 mobile to Android 5.0.2 Lollipop and I have been using Clean Master notification toggle. After this upgrade mobile data is not working by pressing on the mobile data symbol in notification toggle. Pressing on that is taking me to Settings > Data Usage.

Since Lollipop, 3rd-party apps can no longer toggle mobile data without root. However, there's a handy new data toggle in the stock quick settings; tap the signal icon, then tap the toggle in the top-right.

Well I may have found an answer for this data toggle issue. Because I too can't live without one. But unfortunately this only works if you own a Samsung smart watch.

I downloaded 'instant settings' for my Gear S. This app allows you to control certain toggles for your phone, such as; Wi-Fi, power saving mode, sound and of course a data toggle.

Well what do you know... The data toggle actually works. I can turn my mobile data on and off by a single tap on my watch. I guess this will have to do for now.

Just thought I'd try and help out by giving you guys my solution for the time being, hope this helps. ☺


Push Android Exchange Calendar to Google Web Calendar Let me start off by saying this question is essentially an updated version of Access synced Exchange calendar from desktop browser but not a duplication

I have a work phone with Exchange access over VPN, let's called it me@work.  This syncs to an Android phone running the VPN tool but uses my personal Google account me@home.  I don't want or need to carry the work phone around during non-business hours, but it's great to know "oh I have a meeting tomorrow morning" or when making personal plans to know what my schedule is like without having to say "Let me check my work phone later to make sure I'm available"

me@work uses the Google native calendar app on Android.  I don't currently sync my personal calendar to my work phone, but me@home is the main Google Account on that phone.  Is there anyway to publish/sync those appointments to https://calendar.google.com/calendar with an app on Android?  This would enable the events to show up on the webpage, and since they're syncing with my personal Google account they would likewise show up in my personal phone.

As bonus points, is there a way to have this be a one-way or isolated sync, so my work calendar doesn't show personal events?

My company's Exchange server is only available over VPN, so I can't just sync directly to my personal phone.

It is a little bit late but maybe there is a solution now: Someone else had the same problem and asked me for a solution. I have created an Android app for this purpose now. It can copy/sync a calendar (e.g. your Exchange calendar) into another calendar (e.g. a new Google calendar that you create in your me@home Google account). This way you can see your work events in your me@home Google account but your personal events won't appear in your me@work work account.

It is a one way sync from your Exchange account into your Google account:

Exchange (me@work) -> Android calendar -> SyncCal -> Android calendar -> Google (me@google)

You can find the app here: https://play.google.com/store/apps/details?id=com.calengoo.synccal

It can be used for free but it also contains an In-App purchase for an automatic sync.

I used an app call e.sync from the Google play store and it works great. All of my work calendar events syncs to my Google calendar which shows up on my personal phone


How to block ads in Android applications? Are there ways that attempt to block ads in applications? It seems that it should be theoretically possible, by blocking web requests to certain sites, for example.

The most popular method is replacing the built-in hosts files with one that forces DNS queries to well-known ad servers to result in 127.0.0.1 (localhost).  This effectively blocks most common ads, and most of the Google Ads in applications.

The downside is that applications can tell that ads are being blocked, and can either refuse to run or otherwise degrade their usefulness while the ad blocking is in effect.

Also, root access is required to replace the hosts file.

Beyond that, I haven't seen anything that can selectively block web requests for arbitrary apps.  For some programs that only use internet access for ads, you could use a firewall app to prevent them from accessing the internet or -- if your ROM supports it (like the latest CyanogenMod) -- revoke the internet access permission from the app.

Again, root access is generally required to set up a system-wide app-level firewall or replace your ROM.

The answer is: theoretically yes, practically no. Several years passed since the question, but adware got even worse.

Best way to "block ads" is to "get rid of code that produces it". This is very hard to achieve, because this would require to get rid of adware roots, which are related to current world's economical model and entrepreneurship. It's like to rehabitate all people around the world, to react ads very drastically and ultimative: "either no ad, either no use of android os/devices". This could happen through children education, via seeding strong idea, like "ads is something criminal like porn/theft/deception and speculation/terrorism/narcotics"... In such way, after several human generations adware would eventually starve, because any "ad-related activity" would refer to organisation which will be considered "codnucting illegal activity" and enormous penalty tax should be applied, and person who publish ad jailed.

There exists other, faster way: It is to create a group, who would develop android alternative firmware, essentially same as android, but with licensing terms explicitly disallowing using of ads, and maybe even some banning/firewall engine, embedded into system and easily tunable by users. Good implementation would be very costly, and it would take time to put it on a very single phone. But that would definetely force android community to react.

That is some effective approaches, but any real action should involve Google, which should "change its mind and become white and fluffy" in order to really get rid of adware in android. This is very unlikely to achieve, with current world's economical model.


Is there a way to access files off a locked phone with a black screen? So my Droid 2 died on me and went grey screen with lines. I can't see anything and I can't access my files.

Is there any way to maybe project the screen or access it so I can unlock the phone?

Since you have adb debugging turned on, you should be able to use Droid@Screen from your PC to control your device over adb. There's nothing to install on your device, as long as the adb daemon is running.

Once you have that going, you can use the device from the PC as you would if the screen was working.

Also, if you know what files you're looking to pull off the device and how to navigate the Linux filesystem, you can grab them with 'adb pull ' from your PC. Again, this depends on USB debugging having already been turned on and previously used with the PC in question.

Did you apply Hard reset(Recovery mode) to get access to your phone.You will lost all of your data but your mobile will start.This is best way to make your phone as when you started it first time.


Android 4.1.2 Settings Subcategory missing I have a japanese phone (Fujitsu F-02e) and recently I did a factory reset. After the factory reset I found out that the Accounts subcategory is missing. Does anyone have any idea how to get it back? Before the factory reset the subcategory was there. Thanks!

I found the solution. I had a Xposed module named AccountSectionRemover active. My fault!


Changed my LG L70 (MS323) runtime from Dalvik to ART and my phone's not working properly. Help? I switched my LG L70 (MS323)'s runtime from Dalvik to ART, after it restarted and said "Android is upgrading..." and it optimized my 64 apps. After it finishes, I get an error message saying something like Unfortunately the system ui has stopped and then my phone restarts and the whole process starts over again. Please help.

ART is experimental at this stage, unless you're on android L (Lollipop) I wouldn't recommend using it.

If you are stuck in ART you can get back to Dalvik by following this thread: http://forum.xda-developers.com/showthread.php?t=2707841

Your device should boot then.


How to select all and delete in Gmail App I have a Nexus 5, there are a lots of sale emails come to my Gmail account. Right now I can only search in Gmail app, but I wonder how to delete all of results like in desktop version with select all and delete?

It is better to make rules and categorize email base on sender, Subject, and then select them for delete. Currently gmail app not provide select all and delete.


How can I make anonymous calls for everyone but contact list? I want to show my caller id to everyone in my contact list but be anonymous for new numbers... do you know a method/app?

One possibility would be to prefix all numbers in your contact list by *31# (which turns the callerID on for that call only), while having callerID disabled in your settings. Depending on whether the phone app is intelligent enough to detect this as to not belonging to the number, incoming calls should still be matched fine (you could of course first try it out with one number to check).

Second possibility is the other way around: Having callerID globally enabled, and prefix manually entered numbers by #31#.

Being unsure which method to use, take a third option and a look at Prefixer, which should be able to do the one or the other for you -- depending on how you configure that app.

Go to Settings → Call Settings → Additional settings → Caller ID.


How do I disable full-screen mode in Chrome for Android? Some time ago, both Chrome and Chrome Beta started going full-screen. That is, I no longer see my status bar. This is a deal breaker for me, as I can no longer see what time it is or if I have notifications.

I have browsed chrome://flags and didn't see anything related to this.

Is it possible to disable this full-screen mode?

Chrome versions:

Chrome (30.0.1599.92)
Chrome Beta (31.0.1650.32)

My phone:

Galaxy Note 2
Android 4.1.2
Verizon
no custom rom or root

I had the same problem, but I saw the exact moment it happened, a message appeared saying "switching to full screen mode". Then I couldn't switch it off. I deleted all data in Chrome, and the problem was fixed. There was no need to uninstall the app, just cleaned the data using the Android built-in Application Manager. It seems some website included code that caused this, and the Chrome for Android simply does not have the settings to revert this. Hope this helps.

The short answer is no. If you feel that this should be a feature then please file a bug on crbug.com/new and let me know. It should have no effect on scrolling as it keeps all the settings and state exactly the same, if you are seeing problems with scrolling such as events not firing then that is due to the way the compositor works.

The reason why not is that this is a feature on all mobile platforms and we have parity with their way of providing the user with more vertical real estate.


Do Android Stock Browser, Firefox Mobile and Opera Mobile use proxy server to perform rendering It is quite interesting to know that, Opera Mini is using Proxy Server to perform all the rendering work, instead of relying the phone itself to do it. (http://en.wikipedia.org/wiki/Opera_Mini#Functionality) This will help to reduce required processing work, especially in lower end phone.

Do Android Stock Browser, Firefox Mobile and Opera Mobile also employ the same technique? Current Android Phone is having powerful processing capability. Does the above technique will bring more harm than good?

Will request having to go through an additional will slow down the whole process, compared to letting the rendering work done by phone itself?

In Opera Mobile, you can enable Opera Turbo to use the same proxying technology as used by Opera Mini.

Android Stock Browser does not use compressing proxy at all and I believe neither does Firefox Mobile (though given that Firefox Mobile has plugins system there might be a plugin for that).

Several lesser known browsers in the Market does use similar proxying technique, but I can't recall off the top of my head which ones though.

The stock android brower uses WebKit http://en.wikipedia.org/wiki/WebKit as rendering engine.

The solution adopted by Opera assumes that network speed is there, whilst processing power is not.

These days this is not a given, the new dual core phones have power to spare (SGSII has a hardware accelerated browser!) whilst the 3G network is often congested in main urban spots.

It might improve things on lower end android devices.


How to turn off the camera shutter sound on LG G2 mini? Where is located the camera shutter sound file on LG G2 mini (Android 4.4.2)? Or how else to turn that annoying sound off?

None of the solutions recommended in similar questions here does work. The phone looks like requiring its own solution.

The accepted answer for How do I disable the 'click' sound on the camera app? recommends deleting /system/media/audio/ui/camera_click.ogg. I deleted the file, rebooted the phone several times, however the camera did not stop making the shutter noise. N.B.: My phone is rooted.

I want either to delete the file or replace it with an no-sound file, however the location given in the related question does not seem to work on LG G2 mini.

The solution with setting ro.camera.sound.forced=0 in build.prop does not work either.

Explanation to avoid some off-topic answers:

LG G2 mini native camera application has 4 predefined shutter sounds, with no "None" option.

I don't consider switching the phone on silent as a solution.
I am not asking why LG does not have the option (whether it is somewhere legal or not), but how to turn the sound off.
My phone is rooted so I can change system files. I just haven't found which files should be changed and how.
The problem might be deeper. As the description of the Camera Sounds Off! application says:

  Don't work on some devices by ...

  *LG (The LG's camera app has own not removable sound files!)

Actually, I don't believe in anything really "not removable" :), but removing them probably will require some trick which I have not found.

You need to be rooted to do this!

Download and open any root browser. (I am Using Root Explorer for these instructions, ES File Manager works also)
Go to System
Go from Read Only to Read/Write
Find Biuld Prop
Open with text editor
Find ro.camera.sound.forced
Change the 1 to 0
Save Changes
Reboot

You were on the right track. You only have the wrong file it is shutter.ogg that makes the sound !!!


Netflix shows 5.2 error on Samsung when trying to watch series and movies For some reason, I am suddenly getting a 5.2 error when I try to play videos. I found this on Reddit, but no one found a soltuion. Rooted devices can fix it, so here is my question:

Is there any way to solve the error on unrooted Samsung devices?

Checked the Netflix help center, but the 5.2 error isn't listed.

As usual, removing the app, clearing data, restarting device, tried over 4G, restarting netflix app, tried online and offline, previously viewed and unviewed, series and movies and every other suggested solution to different errors.

Nothing works. Any ideas if this is fixable, or if it is a Netflix issue?

Checking reviews on Google PLay reviews of the Netflix app and Reddit (see link above) there are a lot of people affected by this (5.2 error). It looks like it is Samsung only, as I can't reproduce it with my tablet (non-samsung)

I recommend you contact netflix directly. There is an old APK that they will provide to circumvent this problem. its a temporary fix but it works

We need to wait, this happens since samsung S6 last update, netflix must update there app. until than, wait, wait and wait


"X seconds on battery" problem I recently bought a Galaxy Note 10.1 (2014) -- after I opened it, I saw that charge level was %50+. While I was using it, it shut down; and I couldn't open it for a while. I plugged the charger and waited for a while, then it opened with again with %57 charge level. Now it is still charging but whenever I open Settings -> Battery part, it shows a graph and it says "18 seconds on battery" (I don't know why 18, I couldn't see an example on the web). Moreover, the applications it shows seems a bit weird. I see a "Phone" app where there is no visible phone app at the widgets and apps section, as I do not have 3G, or this is not a phone, it is natural. I don't know what is going on, may be someone can guess what is wrong with the battery part...

You need to use the Samsung charger, or at least a wall charger.  Same thing happened to me.


Gboard: Is there anyway to switch language by swiping spacebar? I have two languages on Gboard and when I want to switch between them, I have to press the globe button. Is there anyway to switch language by swiping spacebar?
I've seen this feature on Samsung Keyboard and I was wondering if it's available on the new Gboard.

There is no as such settings that enables you the Language switch on the basis of swiping Spacebar.

But there are two options you can set in the settings.

1. Enables the Switch Language Key:- It enables you with the same features like swipe to change the language, on Clicking on this Globe Switch key your language will get automatically switched based on their preferences in the Settings.
if you have to do more with the language then this is the best option.

2. By clicking on Spacebar:-
if you have disabled the Language Switch in Settings. then you can get the language Popup by clicking on the Spacebar.

Swiping the spacebar is available in Hacker's keyboard.


How many apps can be installed on an Android device? How many apps can be installed on an Android device? Is there any limit in number? Or whether it depends on RAM/Storage ?

In the source code of Android M that you can find here, is this statement:

/**
 * @hide Range of uids allocated for a user.
 */
 public static final int PER_USER_RANGE = 100000;

In this line of code, it states that a user can have one hundred thousand UIDs.

However there is a conflicting information. You know that root UID is 0 and system UIDs start from 1000. Normal user apps start from 10000. This interval defined for user apps' UID numbers is also stated here as:

  FIRST_APPLICATION_UID has the constant value of 10000 (0x00002710)
  LAST_APPLICATION_UID has the constant value of 19999 (0x00004e1f)

Therefore, first UID that will be given to a user app will be 10000, and last one will be 19999. Therefore, it states that a user can have ten thousand apps.

So, which one is correct? I think this might explain. Before 4.1.1 LAST_APPLICATION_UID was 99999, allowing ninety thousand user apps as the limit. However, this is for user apps while PER_USER_RANGE doesn't specifically say so and therefore probably includes all UIDs from 0 to 99999. After 4.1.1 LAST_APPLICATION_UID was reduced to 19999 but PER_USER_RANGE was left untouched.

So for pre-4.1.1 versions, the limit is ninety thousand user apps and for 4.1.1 and after it is ten thousand user apps.

That is of course the limit that Android accepts. But in most cases, your storage will be full before you can reach such numbers.

Citation needed

You can install as many apps as you want to the device but...

If your like me and use a good Chunk of your internal storage just for apps and you have a 8GB phone or tablet as the Android Operating system will take a chunk as well and leave you with about 3-5GB of available storage you are limited to the devices storage capabilities but a good rule of thumb is to have 128Mb per GB of storage for device usability without getting random crashes from stable apps and not usable situations for apps that are not so much stable. It is also a good idea if you have a Micro SD card slot in the device(s) you have the apps on and send them to the SD card by going in settings and tapping on

Apps
Tap or scroll to On SD Card
Select the app in question and tap Move
"Move" will possibly cut up the app (depending on device and or app requirements) and send all data including app data(again depending on device and or app requirements) to the SD card or not be available at all to move. If you have a device that has no SD card but supports OTG(On The Go storage it will not be possible to have the apps sent to the OTG and be usable whenever you want due to the Mount protocol as it is not the correct mountable hardware
be aware that not all data can be sent to SD
assuming that you can make it this far with the device, wait till the grayed out Move is pressable again then repeat till complete
Please note that some apps that can move to SD may work better on the devices internal storage

Also be aware that the more apps you have the more possible resources (RAM)(Random Access Memory) can be used in the device in question as let's say you have 12 apps that request a refresh in the background (like Facebook, Gmail, Twitter to name a few) the less RAM can be found for other operations and causing ANR(App Not Responding) messages and drain the battery faster than expected


How can I mount a USB flash drive on my Acer Iconia? I have an Acer Iconia A500 tablet with Android 3.1. I cannot mount any USB flash drives. File Manager HD and other similar apps display "Directory is empty" in /mnt/usb_storage/. I have tried use a flash drive formatted FAT32, and my USB port works (I've checked with a USB mouse).  How can I get this to work?

You have to use File Manager HD and do the following Steps :

On the panel at the left tap Storage.
On the panel at the top right press the Up arrow until the first directory entry is asec.
Now scroll down through the directory and you should see usb_storage.

4.Tap usb_storage and you should see your data.

Hope i will help.

From : http://androidforums.com/acer-iconia-tab-a500/358421-iconia-a500-cant-browse-through-usb-flash-drive.html

Being 8GB I believe it could be a way the flash is using mass storage.
Although all drives should be seen, not all are setup by each manufacture the same.
Have you tried to format the flash as a 2GB fat32 to determine mass storage feature for the drive or for the tab?
I assume that this flash is valid as you have been able to format it.
How do any other flash drives work?
I also found quite a few HP flash drives have issues as they attempt to install the extra software from the minor partition.


Are iOS apps faster than android apps since android apps are interpreted? Android apps are interpreted rather than compiled. Does this make them slower than iOS apps at runtime?

Java isn't interpreted on Android. Android apps are compiled to bytecode by the developer. Bytecode is a compact representation of the program: smaller than the source code written by the programmer, but still not directly executable by the CPU. Some optimizations, such as dead code removal, can be made at this stage.

When you load the app on a device, the Dalvik JVM compiles the bytecode to native executable code, just as it's about to run. This is just-in-time compilation. It causes a brief slow-down while the program waits to be compiled, but after that there's no performance overhead, because the code has been compiled to native executable code.

There are some performance advantages to doing it this way instead of compiling up-front on the developer's computer. The app can be compiled for the particular CPU on the phone, taking advantage of its hardware features and using its performance characteristics. For example, it can use hardware floating-point operations if the CPU supports it. In addition, a clever JIT compiler (admittedly, Dalvik is not quite this clever) can monitor the way the program runs, and perform optimizations based on the way the program is used in real use. It might recompile the code with better branch hinting once it has seen which options are turned on and off in your environment, on your phone. An up-front compiler doesn't have this information to use.

Dalvik uses the Dalvik cache and other techniques to mitigate the drawbacks of JIT compilation. The new JVM for Android L and later, ART, replaces the JIT entirely with an ahead-of-time compiler. This compiles the bytecode to native executable code when the app is installed, to get most of the advantages of JIT without the delay loading the app.

Don't forget that Android apps don't entirely consist of Java. Developers have the NDK to write all or part of their apps in C or C++, for performance-critical parts of the app, especially for games. Special-purpose interfaces like OpenGL and Renderscript let programmers take advantage of special hardware like the GPU and SIMD coprocessor for some kinds of computation.

So really, there's no simple answer to your question. Using JIT instead of up-front compilation makes some things faster, some things slower. It's just one part of the overall performance of the OS.

Because interpreted apps does not means that they are always slow. Sometimes they are more powerful and dynamic as compared to compiled one. As all codes in compiled app are compiled once & output is kept in form of libraries or executables, while in interprated language, once can randomly change the sequence of execution.
So i can say, it depends of developer to developer and there way of programming.

However, Java (Android's programming language) is not interpreted but is JIT compiled. That means that Android programs compile just before you run them, giving reasonably similar performance to iOS' Objective C.

More recently, Android's ART framework pre-compiles the apps, so they are run in the same way as iOS apps. In other words, the next version of Android will presumably be just as fast as iOS.

Update

Programming languages generally fall into one of two categories: Compiled or Interpreted. With a compiled language, code you enter is reduced to a set of machine-specific instructions before being saved as an executable file. With interpreted languages, the code is saved in the same format that you entered. Compiled programs generally run faster than interpreted ones because interpreted programs must be reduced to machine instructions at runtime. However, with an interpreted language you can do things that cannot be done in a compiled language. For example, interpreted programs can modify themselves by adding or changing functions at runtime. It is also usually easier to develop applications in an interpreted environment because you don't have to recompile your application each time you want to test a small section.


Is there a way to force apps to use internal memory only? I have a Sony Xperia U, and my 8GB of memory are divided in three parts: 2GB phone memory, 4 GB internal memory (replacing the MicroSD slot) and 2GB that I haven't really figured out about.

I don't want to mess with repartition. I just want to use each one as they must be used.

The problem is: many apps are optimized to save many things in SD, but for this phone it is not really useful, as it has plenty of space in phone memory! What can I do to make automatic created app data use internal memory only, leaving SD (internal, in Xperia U's case) free for my own use?

Edit: Thank you for your answers! John, my device is rooted, so, could you explain further about those permissions, please? Thanks in advance!

you say your phone is rooted, it is then possible to change the default installation location that the packagagemanager uses to install apps. this will only work with apps that allow it, as others have already pointed out, apps may choose to ignore the packagemanagers recommendation and install to internal/external anyway even if you choose the opposite. also, big game files in the obb directory are stored where the obb directory actually is located; this is dependent on which phone you use.

to change the default installation directory:

1) use terminal emulator from google play (or, alternatively, enable usb debugging and use adb)

2) in terminal emulator, enter:

su

accept the superuser request, then try either:

pm setInstallLocation X

or:

pm set-install-location X

where X can either be

0 = let packagamanager decide

1 = install on internal by default

2 = install on external by default

Try using Lucky Patcher and installing the app's apk as a system app.


Flashed addonsu-arm-signed.zip on LineageOS, still no root I just installed LineageOS 14.1 using TWRP.

Then, following this guide I downloaded addonsu-arm-signed.zip to my SD card and installed it, also using TWRP.

PROBLEM: Then I installed Titanium Backup from Play Store, an got this message:

Is there a mistake in my procedure?
Is there a missing step?

Go to Settings.
Click on About phone and then tap 7 times on the Build number.
Navigate back, open Developer Options.
Tap Root Access.
Select Apps or Apps and ADB.

Now you have root and Titanium Backup finds it:

I just found I had to switch from ADB only to Apps and ADB. Not sure why, since the issue was with ADB itself.


Is there a way to preserve tabs that were open in Froyo 2.2's stock browser? When my Droid X's Froyo 2.2 browser gets killed for whatever reason (reboot, memory manager killing it), it loses 100% of its open tabs and reopens with Google's home page in a single tab.

If you have 7-8 open tabs, restoring them from History (especially if some were used via Google Mobile URL that all look the same in history tab) is a uber-major pain.

Is there a way to preserve tabs that were open in Froyo 2.2's stock browser, ala saving session state in Firefox, IR or Chrome (at least on desktop)?

NOTE: "Upgrade from Froyo" is not an option, neither is "use FireFox mobile" - for some reason FF and my Droid X don't play well (FF gets completely frozen once an hour usually requiring full battery pull). The question is specifically about Googe's Android Stock browser.

However, if the stock browser from Android 2.3 and on fixes the problem AND can be installed on Froyo 2.2, I'm quite happy with that as an answer.

P.S. Ironically, my problem is the opposite of the one discussed here.

Perhaps Chrome will work on your phone -- it works nicely on mine

adb devices doesn't list Samsung Galaxy S Cyanogenmod 7.1 I am unable to list my device under adb devices and my problem is similar to that of Mad Scientist except that in his case Windows took the Google Drivers from the android SDK.

Ever since I have installed the Cyanogenmod 7.1 on my Samsung Galaxy GT-I9000, Win 7 recognizes the device as a Portable Device, Manufacturer as Android and Location on UMBus Enumerator. WUDFRd.sys and WpdFs.dll get loaded as shown in this image

I have tried to uninstall this driver but it automatically gets installed every time I connect the device. My device always looks like a mass storage device. I am unable to install android_winusb.inf from android-sdk\extras\google\usb_driver.

Windows 7 returns an error saying  -

  The INF file you selected does not support this method of installation.

How do I install the correct drivers so that my device is listed in adb devices?

Connect your phone
Open the Windows Device Manager
Open each relevant device (if more than one is shown), choose "Update Driver", and select android_winusb.inf

I also contributed a lot of time to the ADB problem. (Galaxy P7510 vs Win7 64bit)
After struggling with non-offical drivers, android_winusb.inf, 64bit JDK, and even having virtualized a 32bit OS..,
finally I found a work-around! just come back to share with anyone concerns.

Reference: Connect to Android with ADB over TCP

The above instruction requires a PC which can ADB to your tablet over usb.
Better work-around is root your device firstly, and then download a adbWireless utility,
so you can switch your tablet to ADB TCP mode even without USB connection at all.

HTH!


Partitioning SD card on Android phone I have a 32GB SD card which I want to have it partitioned.

I'm having the hardest time finding any apps that work or any tutorials.

Can anyone please help me out with this?

Are you rooted? There is no way to edit partitioning directly from the device without root, once you have root privileges, there are several apps which allow for the card to partitioned, such as AParted or Parted4Android.

If you have custom recovery, such as TWRP or CWM, some of those builds have SD card partitioning built in.

Remember that Android will only mount one SD card partition by default, with root you can manually mount a second partition.

You can partition through recovery (CWM) when u go  to advanced options in cwm recovery the option is present over there.


How to get out of non-responding screen swipe on locked Galaxy Edge 6? I have a Samsung Galaxy 6 Edge phone and twice now, the phone has gotten into a locked state, but the screen swipe does not work, it does not respond to finger swipe to unlock the device.  I can push power button to get screen on or off, but no screen finger action has any effect.  I cannot get it to reboot.  Pushing power off button for a while brings up screen with choice to reboot, but that requires touching screen to select reboot.

I pressed power and volume down keys for several seconds to force restart, and chose normal boot from the menu, but after rebooting the issue remains, no screen swipe response.  Booting into safe-mode didn't help either.  I did a factory reset and still no response to screen touch.  Is this a hardware issue and I need a new phone?  Should I use ADB and redownload the operating system onto it?

Verizon had to replace the phone due to hardware issues evidenced by these symptoms.

Always try this last step before concluding. Any smartphone, computer or tab has something they call safe mode which bars installed apps and user system apps from at least running automatically to running at all. Get to google and search how to get to safe mode on your device try it and see if it works. If it doesn't, either take it to service centre, reflash the phone yourself or install a third party OS like Cyanogen of the Samsung Touchwiz is messing up. Many people have been complaining. This is a bug in Samsung ROM's


Why phone sometimes (often) goes crazy and constantly lightens up its locked screen? In general, from time to time, my phone (Galaxy SII) lightens up its locked screen for 4-5 seconds.

I thought: the reason behind can be to show if some messages or calls are awaiting to be noticed (but, with screen locked, it is pointless anyway, because nothing is shown besides symbol entry screen).

But sometimes it lightens up the screen like 3 times in a minute, over 15 minutes.

Why it does that?

Try uninstalling some applications. The same thing happened to me and I fixed it by uninstalling my most recently installed app.

I am one of responsible developer of UzumApps.
We developed app called "wakelock detector"(WLD) for showing statistics of wakelock usage.
It is an alternative app for BetterBatteryStats or GSam Monitor.

If your screen lightens up randomly, then I think some app is holding "FULL_WAKE_LOCK" with ACQUIRE_CAUSES_WAKEUP flag, Check : PowerManager

Our app shows "full_wake_lock" statistics also, which will help you to determine the suspicious app. Most probably it will be the currently running process.
 WLD at GooglePlay


Cannot write files to sd card A few days ago, my sd card became unusable. I tried to copy a few mp3's from my laptop (win 7) to my phone (Samsung S2 plus, running android 4.2.2) and the load bar didn't even move an inch. Eventually I got an error saying "This file cannot be copied. 1) Try again 2) Abort".

The most annoying part is that I backed up and deleted all files (to clean the sd card) an hour earlier, and now nothing works. I tried writing files using usb cable over both MTP and camera mode, without any results. I tried apps on the phone, and still the same error. The sd card is inserted correctly and does not appear to be damaged.

I have heard about the kitkat not being able to write files to sd card (like this forum post) but I think that is only for android 4.4. I have been running 4.2 for a while now, and have never faced this issue before. Phone works perfectly except sdcard.

EDIT: My phone actually tried to launch a software update, but since I wasn't connected to a WIFI nothing happened, no loading bar and no update was started.

How to find out what's going on

As this problem can have many causes, it's important to first figure out the real culprit. Without knowing that, attempted solutions are nothing but guesswork, and the process nothing but try-and-err. So here are a few steps:

Is it a hardware error on the card?
Put the card in a different device. It the same problems occur there, we can rule out your problem is with the device, and it's rather the card.
Is the card corrupted?
You can put the card in a card reader, attach it to your computer, and have it checked there. With a terminal app, you could try the same from within your device, using the /sbin/fsck.vfat tool – but on your computer, graphical tools might assist you.
Check the Android logs for related errors:
Our logging tag-wiki gives you some hints on how to do this. Especially useful might be our question on How can I view and examine the Android log?

The third step lead directly to the cultprit(s) in your case: corrupted files. Deleting those made the card usable again. So next, let's check a few possible causes:

What could be possible culprits?

the card could be physically corrupted.
In this case, the same errors should occur on other devices, and as well on your computer when using a card reader. Only solution for this is to replace the card with a new one, as a "physical repair" is not possible.
there might be problems with the contacts.
Here a few things could be tried, like cleaning the contacts of the card. If the same problem occurs with any card you put in your device, it's rather the device itself – in which case you'd have to send it in for service.
logical corruption of the cards file-system:
The file system can get corrupted. This e.g. happens when you disconnect the card without cleanly unmounting it first. While in such a case the same problems should show up in any device using the card, some might be "more tolerant" on errors than others. So it doesn't hurt to check the file-system for errors – see step 2 in "How to find out" for checking. If there are errors found, the same tools usually can solve them. Re-Formatting the card would be a last resort for this as well.
corrupted files on the card:
The card might be physically perfect, and have no issues in the file-system. But in some cases, corrupted files might led to problems as well – especially if occuring on "central files" Android is always looking for on the card when it's mounted (in the /Android subdirectory, or while scanning for media). If you can read the card using a card-reader on your PC, you can make a backup there and then format the card – copying the files back one-by-one until the error occurs again, and then skip those corrupted files. Easier approach is the one you've taken on my recommendation in the comments: check Androids logs (see step 3 on "How to find out"), and simply delete the culprits (again, via a card reader – as you cannot do so on the device itself, which doesn't correctly mount the card anymore).

Possible solutions

have already be mentioned along the lines, together with the related causes:

cleaning the contacts of the card
checking the card for file-system errors and, if there are any, have them repaired
formatting the card1
checking the Android logs for other hints (e.g. corrupted files, which then should be removed)

1: remark: switching to an alternative file-system type does not affect whether formatting helps, but rather might lead to additional issues – as not all file-system types are supported by Android. Which are, differs from device to device, and depends on the rom used: VFAT is the default shipping with most cards, and hence always supported. EXTFS is mostly supported as Android uses it internally (but might not be automatically detected, as it's not expected here). Other types such as NTFS or HFS are very unlikely to be supported

Try your SDcard with other mobile or a card reader. Make sure its properly working.


What does error 923 when downloading apps from Google Play Store mean? I've seen this error a few times just now, it seems to only occur when I install an app through the Google Play web interface. Haven't seen it when installing apps directly from my mobile device. Device is quite new and has more than enough free disk space.
Couldn't find anything on here yet about this specific error. After a retry it downloads without any problems, so while it is far from blocking, I do hope to get some insight on what is happening here.
StackExchange only lists error 923 as an AndroidRuntime(923) error, but I don't see how that can be the cause here.
Screenshot attached with error in Dutch.

Error - 'Game' could not be downloaded due to an error. (923)

It seems error 923 is related to the whole process of downloading, cache, storage, installation, etc. People get it most often in Google Play, but sometimes also outside of that.
Most suggestions how to fix this come down to:

Settings > Apps > Running > stop all (Google related) running services
Settings > Apps > All > Google Play Store > Clear data and Clear cache
Reboot phone, all should be fine now

Found quite some useful answers on the internet outside of StackExchange (it exists!), so answered my own question already. Suggestions/additions always welcomed. ;)

It is just lack of storage.

the only thing that makes any sense to solve this error on the accepted answer is the clear cache step.


Disable popups on cancelled Sprint service on LG G2 I have an LG G2, and recently got a cell phone provided for by my place of work, so I cancelled my Sprint service.

I want to use the phone as a gaming device for my kids, but I keep getting error messages popping up regarding the fact that it cannot connect to the sprint network.

  LTE : ESM-0 EMM-19
  EHRPD : 5
  MIP : 67

They pop up very frequently, and I cannot find a way to disable them.

TL;DR: Is there a way to disable the popup error messages related to no service on a Sprint LG G2?

Not sure about the error message and making it go away. But you could always put the device into airplane mode and still use WiFi. That should stop the device from trying to connect to the Sprint towers.

You can root your device and then manually disable those popup settings by editing databases using SQLite editor app.

Some manufacturers put their custom apps as ordered by service providers. Theses apps do not have their own UI, but used by other service provider specific apps to get updated values from service provider as per customer-plan.

These apps change default values of certain actions, responses, service access in SQLite databases that are present in Android devices or build their databases which are accessed by Android system.

By using SQLite editor app, user can browse these databases manually and change values that seems to be connected with this pop-up issue. To browse these databases, device needs root access.


BOOTLOADER - USB Device Not Recognized I am currently using a ROOTED "Huawei MediaPad 7 Lite" tablet and am having issues entering the bootloader. When powered on and connected to a PC, the device is seen in adb using the command adb devices (driver is working). However, when I try to enter the bootloader, adb reboot bootloader, the device malfunctions in windows:

The same occurs when the tablet is powered off, and the power and volume up keys are held down (entering bootloader manually). In 'Device Manager', there are NO 'Unknown Devices' missing drivers. Instead, there is an issue with the USB controller:

Due to this malfunction, I cannot install a driver for the tablet when in bootloader mode. To clarify, the tablet works OK when powered on and connected to a PC, but malfunctions when in bootloader mode. I have tried this on 3 different computers with 4 different MicroUSB cables with no success.
I also have a second identical MediaPad 7 Lite, and in trying the above steps also has the same problems. It seems Huawei have done this as a preventative measure (meaning it is a device specific issue), but does anyone know how to make the PC recognise this device properly when in bootloader?
EDIT: The bootloader screen is unusual. Without the cable connected, when the bootloader is entered (by pressing power with volume up & down), the following options exist:

continuing to hold volume up brings up a screen which is used to update the tablet software from a file on the external MicroSD card
continuing to hold volume down initiates an automatic recovery process
releasing all buttons reboots the tablet automatically after a few seconds

With all of the above options, I tried plugging the tablet into my PC. However, Windows does not recognize the tablet at all (nothing pops up).

As the device has failed to be recognised correctly (failed) I would suggest uninstalling the device from windows or updating the driver, however looking up device id in this forum,suggests various other options could fix the problem.


Wi-Fi works well in other devices but shows "limited connectivity" in my Sony Xperia Mini Pro I have a BSNL router in my house. I can connect and browse using Wi-Fi in my laptop and my brother's and dad's mobile but it shows limited connectivity in my Sony Xperia Mini Pro.

It has WEP security. I've used that Wi-Fi earlier but now it shows as limited connectivity to mine alone. Even if I enter the wrong password, it shows "obtaining IP address" and shows "limited connectivity". I've also  used static IP address option in that. It gets connected in that case but I can't browse.

How do I solve this issue?

use dynamic ip address ..and forget network and restart  your mobile  and then enter correct password in wifi network .and  stay in wifi router range.


How to run two Messenger applications logged into different accounts? I have done a bit of research, and that, coupled with some programming knowledge, leads me to believe that it should be perfectly possible to run two separate applications of Facebook Messenger.

Is it as simple as changing the manifest file name? Or is there more to it? How do I run two separate Messengers?

Yes, at the very least that will have to be done. You may also have to re-sign the apk, and also change any absolute references to the Application context inside the java code and/or machine code. This will require lots of effort, you might as well build your own Messenger interface via Facebook's API. Facebook does have a developer API for this kind of stuff, you may want to look into that.

Facebook Developer SDK

I would try renaming the package first, without even decompiling anything, if it crashes due to internal package pointers, I would probably try to build a plug-in.

Hope that helps,

Now, Facebook only support multiple accounts. You can run more than one facebook account in facebook messenger app.

Follow this simple steps to add, remove and switch multiple accounts in facebook messenger.

How do I turn off the shutter sound for the Android camera? Possible Duplicate:
  How do I disable the 'click' sound on the camera app?

If the phone isn't in silent mode, taking a picture using the stock camera application always plays a "shutter" sound. Is there a way to turn the sound off?

I'm using stock Android 2.2 on a Nexus One.

I'm on android 2.1 and am on a Samsung so this may not be exactly the same for you. To disable the shutter sound I launch the camera then (with the camera in landscape mode):

Tap the triangle on the left of the camera frame to show the options round the camera.
Tap the Settings icon (cog) on the bottom right.
Tap the spanner tab on the top.
Tap the down arrow on the right to page down.
Tap the button next to Shutter Sound.
Select Off.

The camera preference or system preference should have this setting, may be you can try to find?


"Unable to connect to the proxy server" after updrade to Android 4.3 My Samsung S4 has been experiencing the problem of "Unable to connect to the proxy server" after upgrade to Android 4.3, all the apps need network (HTTP) are not working, no matter
using 4G or Wifi connection. For apps which does not require HTTP connection such as Whatsapp or Google Search which is ok.

I have double checked the Proxy setting in my Wifi Setting, which is set to none, so are there anything I have missed or misconfigured?

Tap and hold the WiFi button, then select "Forget Network". Afterwards, search for the network again in the list, enter the password and you are good to go.


Enable On-screen navigation in CM12 (Lollipop) using shell? Device: OnePlus One (OPO); running CM12, is rooted, and has Xposed Framework installed.

I need to enable On-screen navigation (it disables Hardware (HW) keys and shows soft keys at the screen; like this) in OPO. I'm able to do it via Settings but my objective requires a command-line solution through shell.

(Note that this is not a development/programming question, simply an Android question.)

Objective: To disable Back(HW) key  when main activity of an app (random) is in foreground, but without a reboot.
I found On-screen nav. to be a good choice which doesn't require a reboot. I'll use an automation app to trigger the disabling action.
There are manual ways to disable HW keys (by editing .kl files) and enabling Soft keys (by editing build.prop), or using tools like Xposed modules to disable or swap HW keys. But they all require reboot (soft/hard) at least once which I cannot afford.
I experimented  and found that when On-screen nav. is enabled, the value for dev_force_show_navbar changes to 1 from 0. Similarly. button_brightness changes to 0 from 255. Both names are under Settings.db (Table:secure)
Also, there is no special activity assigned for Settings → Buttons(it enables On-screen nav). I used dumpsys activity | grep mFocusedActivity to see activity related to Buttons. The result was:

com.android.settings/.SubSettings

dumpsys activity activities or dumpsys activity recents also has nothing more to tell here.
I logged my actions using logcat when enabling On-screen nav. and here is the log file.

So, how do I enable On-screen nav. through command line, irrespective of whether it requires superuser access or not?

Edit: Is there any other way using which I can achieve the objective precisely?

Only thing that comes to my mind is to use  input  <keyevent> but that's counterproductive to me. The other way is to trigger an Xposed module like Xposed Additions but I'm unable to use it with shell.

I experimented and found that when On-screen nav. is enabled, the value for dev_force_show_navbar changes to 1 from 0... Both names are under Settings.db (Table:secure).

You actually mentioned the key to the answer but somehow (I suppose) didn't know how to use it. Many thanks to Andrew T. and DavisNT for this answer since it would lead to a solution for your problem.

I myself is a owner of OnePlus One running stock CM12 so you may now expect a working answer.

From the shell, be it adb, or a Terminal app, or Tasker's "Run Shell" action, enter the following command with root privileges:

settings put secure dev_force_show_navbar 1

You would now see that On-screen navigation bar is enabled just like in your pic posted here.

Don't worry about button_brightness since the changes in its value would be reflected automatically by the above command.

I tested that command in Tasker by manual execution of action "Code -> Run Shell -> command" with "Use Root", and its working good.

The changes are exactly same as doing it from "Settings -> Buttons" so nothing to worry, i.e. only Soft-keys are visible and Hard keys are disabled. Coolest part -- no reboot needed.

You can revert back by using 0 in place of 1 in the aforesaid command.

What I can suggest is - Install Gravity Box and enable the Navigation Bar from there.


Some SMS Display Date, Others Time I'm trying to figure out why some of the text messages on my Android only display the date while others display the time? Do the older messages have the date only?

As FieryCod has already said:

If the message is from today it will show only the time but if it is from earlier it will show the date

As others suggest it is caused by the fact that:

Messages were written/received at present for example you received a  message on Monday and till Monday is not end there is no need to show the information about day and month so it is only the hour displayed.

If the Monday is ended and there is a Tuesday now, there is a day displayed, because the message did not come today but one day ago so it is normal to show the day not a hour which might be confusing.


How to tweak camera/screen for Whatsapp web QR scanner This is NOT a duplicate of Why I can't scan the WhatsApp QR? or Can't scan QR code for WhatsApp web due to camera inverted or tilted on Galaxy Y Duos.

I'm using CyanogenMod 11 (snapshot M12) on HTC One X
I have the latest WhatsApp 2.12.250

I'm trying to scan the WhatsApp web QR code on my computer. On my Android Whatsapp, I'm able to get to the point where the scanner is active, and the green scan bar goes up and down, but it never manages to capture the QR code on my computer screen.

I tried to scan the same code using the ZXing Barcode Scanner, and it only works when I turn on "Use auto focus", "No continuous focus", "No exposure".

The camera lense on my HTC One X is slightly scratched up, and the camera pictures has long been foggy. I suspect that the combination of my crappy camera and the computer LCD screen is preventing me from scanning the QR code.

So, since I can't change the camera setting in the Whatsapp QR scanner, is there any tip on how I can maximize the scannability of this web QR code?

first of all, make sure you have a high speed internet connection.
If so then do -

hold still your phone in landscape mode and try to scan for atleast 10 sec..
(worked for my galaxy-y duos)

I had issues with this due to my wide angle screen. If I moved the QR code to my 4:3 screen all of a sudden the scan would work normally.


my phone glaxey s4 had its screen crashed and Ive changed it and now it wont charge My Samsung Galaxy S4 keeps showing the message "Charging paused. Battery temperature is too low", whenever I plug the phone into a charger. I've tried using a different charger and even another battery but the message re-appears and the phone continues to not charge.

How can I resolve this problem?

Reflash the stock rom using odin.
If it didn't work, change the power socket


What does the "Aggressive Wi-Fi to Cellular handover" option in Developer Settings do? In Android Lollipop 5.0, I noticed that "Developer Options" features a checkbox for "Aggressive Wi-Fi to Cellular handover" that is unchecked by default. Does anybody know what this setting does and why it's disabled by default and hidden under developer options?

The code for shouldSwitchNetwork() best explains what it does.  It just artificially reduces the WiFi RSSI (received signal strength indication) to encourage the WiFi state machine to decide to switch the connection from WiFi to cellular network.  Around line 3559 of WifiStateMachine.java (line 4262 for Android 6.0.1_r10):

int rssi = mWifiInfo.getRssi() - 6 * mAggressiveHandover
        + (homeNetworkBoost ? WifiConfiguration.HOME_NETWORK_RSSI_BOOST : 0);

The variable mAggressiveHandover is an int that is set to 0 or 1 by the Developer Settings:

private void writeWifiAggressiveHandoverOptions() {
    mWifiManager.enableAggressiveHandover(mWifiAggressiveHandover.isChecked() ? 1 : 0);
}

The rssi variable goes on to influence how the connection is classified: isBadRSSI, isLowRSSI, or isHighRSSI.

As to why it's hidden under the developer options, I'd say that is because it seems a little hackish, with a seemingly arbitrary scalar (6) that some dev came up with to nudge the behavior in the desired direction.  Google is probably uncertain about the consequences of this setting and the optimal way to adjust rssi.  If I'm wrong and this is somehow meaningful, I'm happy to admit it and explain here why.

Turning this setting off does NOT turn off cellular handover altogether.  The WiFi connection still gets a score and is disabled if the score is too low.  But hey, the initial score is set arbitrarily too.

No it does NOT turn off the feature completely, nor will it turn it ON by enabling it, it can ONLY be turned ON/OFF in settings → Wi-Fi → Wi-Fi Advanced menu (The three dot icon in the upper right hand corner) and then checking the box next to "Smart switch" (Verizon Samsung Galaxy Note 4 Android 5.1.1), otherwise the only thing that you're honestly doing via the developers menu is simply forcing this same exact option to work if/when your phone is experiencing any type of network "hiccup", and it in a way forgets to change the network type. I suppose you could think of it as a blunt or abrupt reminder to the system to change its internet connection from Wi-Fi to cellular data, and/or vice-versa.

Why does the Android device connect to a secured wireless router without providing a password? During the weekend, I was able to connect to a secured wireless network via an Android device (Asus Transformer Tablet), but when I tried to connect to the wireless network via my laptop it was requiring the connection key (which I didn't know).

Can anyone explain me how was this possible?

I've tried to see the password of the wireless network on the Android device, but (I guess for security reasons) the current password for a wireless network is not shown in its settings.

(The secured network was not previously saved/configured on the Android device.)

Do you have another Android device (like a phone, maybe) that you'd previously connected to that same Wi-Fi point?

Android 4, Ice Cream Sandwich, (and possibly older versions too, though I don't have any to hand to check) has an option to sync saved Wi-Fi passwords between different Android devices on the same Google account. Here's the option under Settings -> Backup & Reset on my phone:

There are also apps that allow you to sync Wi-Fi passwords between your laptop and your Android devices, though I assume you'd know if you had one of those installed.

At a guess, you're actually connecting automatically to another nearby unsecured network rather than the secure network.

How to refresh a web page in Chrome (Ctrl+F5 analogue) on a device without menu button? I have a Nexus 7 Android device with 4.2.2 and Chrome browser.

How can one perform a deep refresh of a web page - analogue of Ctrl+F5 hotkey on desktops?

Please, notice that the device does not have a menu button.

According to the only related question I've found here, the solution is to clear browser cache completely. I'd prefer more convenient and elegant solution.

I found it !!!!!!

On the left side of the URL there is an info icon (i) or a lock icon. Click the icon and then  [web site configuration].

You will find a trash icon to clear cache of the current site, and alternatively a "restore preferences" button.

Working on Android Chrome 71.

To the left of the web address window you are visiting is a nearly circular arrow.


How do I get my wallpaper to stop moving? I just changed my background on my home screen on my Galaxy S4 and every time I scroll to a different page the picture moves. How do I get this to stop?

If you are using Apex launcher, I remember that you can disable scrolling wallpaper in Apex settings, just try to find this option yourself. FYI: Touchwiz launcher doesn't have scrolling wallpaper from Jelly Bean up.

I use wallpaper Wallpaper Wizardrii™ from Google Play Store which exactly matches your requirement. You can find details in the app's wiki.


how to install custom recovery without pc I want to install custom recovery in intex aqua y2 pro  without pc to avoid accidents. i have downloaded the cwm (touch)custom recovery.img(4mb) and the stock recovery (6mb) can i flash it through mobile uncle tools without bricking it
Please Answer

It is possible, but doing so could be even more dangerous than doing the traditional PC flashing way. Flashing it through ADB is much easier and way less dangerous. If you have not already tried flashing the phone, try using ADB. Also, avoid apps like Kingoroot or Kingroot, they are proven as spyware by the community. Have fun flashing your phone!  It's way easier than you thinkGood Luck, Joe.

You need to Root your Phone to Install Recovery without PC using this Following Apps :
- Kingroot
- Kingoroot
- Towelroot
- Framaroot
- Iroot
Choose the one that successfully Root your Phone

Then install Flashify and grant Root Permission, then select Costum Recovery and Select the recovery.img file and flash it

Which apps do gapless music playback? Are there any apps around that are good at gapless audio playback? I listen to a lot of music that continues from one track to another and the stock app puts a small but noticeable gap between tracks.

Try the latest Museek player. It has support for gapless playback. You need to enable it from within the ADVANCED settings in the app.

There's also PowerAmp and Winamp which seemingly offer decent gapless playback quality.

The Amazon MP3 player adds gaps. Luckily you can play songs downloaded to the device with any music player, and Google Music does gapless playback out of the box.


Is there a simple way to undo an app update? I'd like to revert to the previous version and stick with that permanently. Is that possible?

I have Beautiful Widgets installed, and had it set to auto-update. It just did, and the 'update' is totally unacceptable.

I've got several devices, all rooted and running different versions of Android. Some have auto-updated the APK to the new version, some have not (I just disabled auto-update on those that have not).

Android does not natively back up applications so you can't "undo" an app update. Best thing I'd say you can do is something like this howto. It backs up your apks and their settings. It uses Titanium Backup and requires root, but rooting is not your problem.

Simply go to play store, search for that app, there will be two options 'uninstall' and 'open', just simply click on uninstall and your good to go. Dont worry, it wont uninstall your app completely but only the update gets uninstalled. After that you'll see there two options 'update' and 'open' and thats what you always wanted!


Why can't I stop people from inviting me to group chats on kik? Someone has been harassing me on kik all week by continually adding me group chats that I did not ask to be part of. The person is blocked, but they are still able to add me to group chats against my will - I don't have the option of accepting or not, it just happens.

If I have to abandon the platform and find another way to talk with my friends overseas I will, but I'm hoping there's some way I can stop this. (And yes, I've reported the offending user to kik support, but they're terribly slow and now it's the weekend...)

I apologize in advance if this isn't a good community for this question, I just can't find an answer anywhere else I can't believe that there isn't one.

The answer is: you cannot. Either wait out the harassment, don't open the app for a while, or switch discussion platforms with the people you care to talk to. All unsatisfying solutions, but... they are the only ones.

If you want them to stop why don't you make a new kik? I have done the same blocked and it still happens I don't understand why but just make a new one or simply email kik messenger and report that person.


How can i take picture to call a number I think there was option in some app, dont remember what it was. But you could take picture to call it.

I want to simply take picture of a number and call the number. Photo need not to be saved.

It'd be huge benefit to me.

I think it should be possible i'm not talking about hand written numbers, i'm talking about numbers on screen or billboard etc.

Google Goggles will do what you are asking. It does an analysis of any taken picture (without saving it to your phone). The results of the analysis will depend upon your picture (for example, if you take a picture of a famous painting it will tell you what the painting is).

In your case if you take a picture of a phone number, it will highlight the number in the picture allowing you to select and dial it.

Use a QR code. Scan the QR code with your camera, and make sure that a phone number is set as the content within the code. You should then get an option to open the number (as usual) with your preferred dialer.


Disable "unlock with voice" notifications Xperia XA1 tl:dr - despite repeatedly choosing the "no thanks" option, my phone keeps displaying notifications to setup voice unlock. I Say "no" - as far as I know it is not enabled - but an hour later it asks me again.

How can I disable this feature permanently. (re-asking me to setup voice notifications).

Phone is Sony Xperia XA1 running Android 8.0.0

longer:

Starting yesterday, I got a notification saying "Unlock with your voice" - "Unlock your phone by saying "Ok Google". (screenshots at the bottom of the question)

Now, being a privacy conscious tin-foil hat wearing type - I do not want my phone to ever be listening to me for voice commands. No problem, I tap the notification - and another page comes up with a description, and two options: "No Thanks" and "I agree". I choose, "no thanks". The phone seems to be content with my decision. But.... an hour or so later, the notification returns. It's happened about 3 or 4 times now.

Screenshots:

Remove Google Now Launcher (discontinued) from the homescreen and disable Google from Settings > Apps > Apps List.


Will cutting the sound cables do any long term damage? If anybody read the question here I have now commited to dissecting the tablet completely, because SCIENCE! Anyway, only one thing is keeping the back connected to the main tablet: the two cables that connect the main motherboard to the speaker.

So, this is it:

So, to my question: will cutting these cables result in unfixable hardware issues. To clarify,  by unfixable I mean destruction of hardware e.g. cutting off power to an important segment. The obvious lack of sound is no issue to me, I can just wire it back if I want (which I won't, for personal reasons)

You should be fine (95%). It's nothing more than electricity. Just make sure to seal it up really well when done modifying your phone.


How to set my wallpaper from my Dropbox? I have copied a bunch of images into my Dropbox on my pc and sync'd them to my phone. Does anyone know how to use these images for wallpapers on my phone?

The only way I can think of is that I can use something like Astro to copy the file to my gallery locally on the phone, or to share my dropbox pictures folder on the web and browse to it.

Although copying the file into dropbox and then copying it again seems crazy. Is there a better option?

You're right I just played with trying to set a Dropbox image as my wallpaper, and can't believe that there isn't an easier way. Part of the problem seems to be that if you Open a dropbox image, it isn't sent to the Gallery or the system default image viewer (which would let you do things like set as wallpaper) but Dropbox uses its own (HTML?) viewer.

There are feature requests in Dropbox's "Votebox" that are requesting features that would fix this. It's probably worth heading over there and letting them know that you'd like this feature, this option looks like the most likely (but you can just go to Votebox and search for Android to see all the relevant ones):

Add Dropbox photos to Android gallery

Update: If you download photos from Dropbox, they do appear in the gallery in a folder called "Photos". Now that they're in the Gallery, you can set them as wallpaper the same as normal. You might need to force the media scanner to start before they'll show up in the gallery, this previous question has options for forcing that to run.

Open dropbox view camera uploads press circled arrow of chosen pic, select more, then select open with, choose 'gallery' wait for jpg to open then press your own phone menu button ( in samsung bottom left corner) select set as then proceed for wallpaper or home screen. :)


What should I do now to move apps to SD in my Samsung Galaxy S Duos (ICS)? I just bought a new Samsung Galaxy S Duos and the Android version does not have a option to move the app to memory card. I also installed the app called "app2sd"and when I open the app it says, The device does not have a real primary external storage or the primary external storage is emulated. Moving app to SD function may not be supported by this device.

What should I do now to move the app to SD.

I have LG P768 Android 4.1.2. I can move apps to SD using Move2SD

some app2sd (that can't work) will show this error "device does not have a real primary external storage or the primary external storage is emulated"

Follow this link . All the details given in it . If it does not understand your external sd card as memory device you might have to create a new partition in the sd card . Here is a link for that


App permission management is running notification Is there any option to get rid of those not useful, permament notifications on Android 5.1, in particular App permission management is running

They are just taking space and focus, are not helpful to the user at all.

Edit: please note that I'm asking about the notification messages, not the icons.

I am sorry to say that it is not possible without root access.

If you do have root access, then there are a number of options. One simple method which I have used in the past is an app called "Notifications Off" from the Play Store. Another more advanced option is to use GravityBox via the Xposed framework.

But care needs to be taken. You can only choose between all or nothing for a given app. Therefore it is only safe to disabled the App Permission Management notifications if you have Permission Management switched off, otherwise you will miss all the dialog boxes which occur when an app requests a permission, causing many apps to be completely unusable.

Follow these instructions:

Launch Settings app → "Sound & notification".
Under "Notification" go to the entry "App notifications". You can search for application you want to block, open it, switch the "Block" button and you are done.


Samsung galaxy Tab 3 won't show up in My Computer? I am trying to root my tablet and it won't show up in My Computer when I plug it in. I have tried different ports and have tried rebooting the phone. I just purchased it 5 hours ago. I have Windows 7. I installed some Samsung drivers, but I am not 100% sure they are the ones I need (I got them from a guide).

I don't have an SD Card, but I do have 8 GBs of internal memory. I have Samsung Galaxy Tab 3 T210R with WiFi.

Thank you!

Try google search: 'usbdeview' and download it.
Now delete all drivers with the Vendor ID '18d1'
Search Google again for: 'Samsung Galaxy Tab 3 Drivers' and download and install, else use Google's USB Drivers: Search Google for 'Google USB Driver'.

Install them, and try and plug it in again.
On your tablet: Go to Settings -> Development Settings - > Tick USB Debugging.
You might wanna change your USB Storage to 'Charge only' or 'Camera' if possible. Else try to search Google for: 'Samsung Galaxy Tab 3 root'.

I hope I helped.


Why do I need more than 200 megabytes of disk space to install an APK? I started to get not enough space errors when updating or installing APKs, but I have 200 megabytes of free space on my internal storage, 2,68 gigabytes on my internal sdcard, and 3,62 gigabytes on my external sdcard. I can't imagine what could use more storage than 200 megabytes in the process of installing a 4 megabytes APK. I'm constantly deleting apps, moving them to sdcard, but I only end up having less and less space remaining. How does this work? I want to understand the inner mechanism of how storage is handled when installing APKs, or in situations that can affect it, so maybe I could write an app to help this procedure.

Edit: I'm using BAM Android on a Samsung Galaxy S2 (i9100).

internal memory space is required to store app data and cache, it doesn't matter much if you move your apps to sdcard app data and cache still gonna be in internal memory.
this problem can be solved by rooting.
if not willing then try some apps playstore which delete cache and auto move apps to sdcard


How can I drag and drop files to Nexus 7 from a Windows PC? I have a Nexus 7 tablet and Windows 7 computer. I can see the tablet in the device manager as a Nexus 7. It shows up as nexus 7 when I view it on my PC as a drive.

When I drag a photo to the tablet from the pc, the photo file on the nexus 7 shows up there. I cannot view the photo no matter what I do on the tablet, it says 0 photos. I also cannot get any video file to play on the tablet after I drag and drop it.  No sign of it on the tablet, but I can see it in the folder on my pc.

I am using USB. This is so frustrating.

Please see that the photo and video formats are supported by default. Else you might need to install apps that are available in google play. Use a file manager to open the picture by browsing to the location. Once you open it, they might start appearing in the gallery automatically.

AirDroid is great for that. I personally use it for everything. You can drag and drop files from desktop to your Android, or vice versa. You can access or modify clipboard, you can view your file browser, music player, you can send SMS, track your device and more.


Custom Alarm sounds removed? This is what I am currently running:

Verizon Motorola Droid 4
Android Version 4.1.2
System Version 98.72.189.XT894.Verizon.en.US
Last update Nov 21 2013

Prior to this Nov 21st update, I was able to set a custom ringtone, notification, and alarm on my phone. Custom meaning I can upload a sound file of my choice and have my phone play it.

After the update, I am still allowed to set a custom ringtone and notification, however I am prohibited from setting a custom alarm sound.

Is it possible to still choose my own alarm sound without rooting or installing an app?'

Note: Previous question/answers don't concern this update or suggest installing a third party app.

EDIT: To change alarms, I go to: Apps -> Clock -> Set Alarm -> Settings. When choosing an alarm sound, I am only allowed the default selection from the phone, whereas with ringtones and notifications (in System Settings -> Sound), I am able to select from my custom made sound files.

The folder Media is the where all the Sound files are actually stored. Inside Media, it has its own Alarms, Notifications, and Ringtones folder. These are the folders where each respective sound file belongs.

In my case, I wanted to create a custom alarm. I thought it would be as simple as dropping a sound file in there, but it wasn't. THERE'S A TRICK. In order for the Android phone to recognize your file as an actual alarm, the file must have Alarm appended to its name.

Example : If your song/file name is Unwell.mp3, then you have to rename it to Unwell Alarm.mp3.

Only after you include the Alarm in the name will it become an Alarm.

There is a folder called "Alarms" in your SD card. Just paste the sounds/songs you want to set there and it should appear when selecting sounds for the alarm.
