App to allow me to set which contacts dial out with Google Voice by default? I'd like to be able to set, at the contact level, which phone number is used to dial out.  For example, I'd like to be able to set it so calls to my boss use Google Voice by default where as calls to my family use my cell number.  Any suggestions?

I still haven't tried Voice Choice, but I just downloaded this free app: Voice Plus

This looks perfect.  From the description:

Allows you to set rules for which number dialed will use your Google Voice number. Specify rules based on area code or by contacts (using contact groups). No more annoyance of having to press another button when dialing to choose where to call from!


Do any Android phones support 256GB of storage? I'd like a phone, preferably Android, with 256 GB of storage.

To the best of my knowledge, no 256 GB microSD cards exist (despite a few scammy Amazon listings).  Therefore, the phone would either need to have (1) a fullsize SD slot or (2) dual microSD slots.  I don't know of any android phones that have a fullsize SD slot, although there are of course tablets that do.  And the only Android phone I know that promised dual microSD cards is the vaporware Saygus V2.

Do any solutions exist that don't involve solder or external devices?

A quick search on Amazon gave a bunch of results.

SanDisk Ultra has a 256GB model (red and pale yellow)
Samsung EVO+ has a 256GB model (red)
Samsung EVO Select has a 256GB model (green)
Other manufacturers also have 256 GB models, e.g. Patriot LX and ADATA Premier
Lexar has 256GB models but I've heard they're ceasing producing storage products

Oh, there's one more thing that I'd like to note: The "maximum supported storage capacity" actually depends on the SoC (chip) and system. So as long as your phone is running on an SoC later than 2015 and Android 5+ (Lollipop) then it should have no problem supporting a 256GB microSD card.

Moto X Force is one phone it supports cards up to 2TB. Though currently I don't see cards with capacity more than 256GB.


Is it possible to change the button combination for recovery/download mode? I had to press power + home + vol up/down, but my home button just stopped working.
Is there any way to change the key combination?

(I can go into recovery by using the reboot menu, but it would be better if it worked.)

Samsung Galaxy S (I-9000), Android 4.4 (CyanogenMod 11)

Try holding down the volume up, then camera, then lock button. If this works then use the up/down volume keys to select what you want to do.


If I root my phone, can my service providor tell if I am using my phone for USB tethering or as a WiFi hotspot? Looking at the responses to this question, it seems that a mobile service provider can't automatically detect whether or not a phone user is tethering their phone or not. Though they can infer it by the type of activity a user does.

However, my service providor charges extra for both USB and WiFi tethering. They can provide accurate usage statistics and charge by the data packet, so they must have some deliberately set up way of monitoring this. I believe the most likely way of doing this is they likely have some kind of software built into my installation of Android that reports whether or not I'm tethering.

So, does that mean if I root my device, and then presumeably that software is gone, they won't be able to tell anymore?

I'm weighing the risks and rewards of rooting my phone, and whether or not I could bypass their nickel-and-diming by charging extra for tethering would be a deciding factor.

Technically they can inspect the HTTP Headers and look at the User-Agent field to determine browser and OS; but imagine the millions and millions of HTTP requests for web pages and applications in a given day.

They can do trends, and data mining techniques to find out - but is it worth all that effort for them just to track down someone using a few more MB of bandwidth? Probably not.

Is the app from the carrier itself? If you root your phone and install a custom ROM you are erasing the phone and anything that was pre-installed by the carrier. It should work fine after that, or if you have a international version of the phone. Also, they can only see how much data you're using, and they just make it slower if they see you're using too much.


Cannot open message application on Samsung Galaxy S2 and Deleted all of my Contacts I was originally getting an error message about the logserver not working, which I fixed through managing the application and forcing it to close, but now I get another error when I try to access text messages:

  The application messaging has stopped unexpectedly.

  [Force Close]

Then it doesn't let me access messages. When I cleared the data from my contacts like someone advised, I deleted all of my contacts, and messaging still doesn't work! There was not an option to clear the cache data, and when I try to sync my contacts to my phone from Facebook and my Google account, NOTHING happens.

I need to get my contacts back somehow and figure out how to get the messaging app working. I have tried to look up solutions but I don't understand what most people are saying and I am so frustrated. I do not understand what it means to be "rooted", although I did install the app ES File Explorer which seems to have done nothing.

Can someone please help me?

The only way that I have tried is to download GO SMS Pro and delete the longest message.


Cannot install apps from Google Play Store due to insufficient space I have an SD card which is 3 GB, but I only have 4 downloaded apps and the  internal storage almost reach its capacity and thus yet I have an insufficient space problems.

Try clearing cache for your internal storage and transfer "unimportant" files to your memory card, this will create some space for your apps to be installed.

Uninstall the new Google Play Store App to factory settings every time you want to download a new/updated apps. I know this is a pain of a * but this works because it does not leave room for your Google to check updates, like Google books for daily newspapes or magazines which needs the space even if we do not use that app. I even hate how the new app looks and now in Google's newest version (5.3.6) they hide details for memory and price along with other details.


Android Decrypt SD Card after Factory Reset I have a Galaxy Note2 device, Android 4.4.2, in which I have my extCard encrypted using the settings option, for a force majore I had to reset factory settings. now i can't access my important files on the SD Card and there is no option to decrypt it. I know my password but there is no option on the phone to do it.

I've tried Encrypting my device with the same password .. but it didn't work.

Any Ideas?

Yes just go to encrypt sdcard and select encrypt but dont apply it then you can select decrypt and use your password


How to change default PDF viewer on Nook Color? I just upgraded my Nook Color to the
new 1.2 version that supports apps.
I purchased the ezPDF Reader app
which supports bookmarks and other
advanced features for PDFs which the
default Nook Color PDF viewer does
not support.

Is there a way to make the ezPDF Reader the default PDF Viewer?

(Currently when I click on a PDF the default viewer still opens)

To Clarify:
Currently I have to open the ezPDF Reader first and then open a PDF from within the app. If I simply click on a PDF on a book shelf or on the home screen then the default PDF viewer opens the PDF. I don't see any area in settings like on a regular Android phone to modify installed apps or app settings.

Find the app that took over the PDF intent in Menu -> Settings -> Applications -> Manage applications -> All, and then tap on Clear defaults button.  Next time you click on a PDF file, it should prompt you which app to use.  Check the Use by default for this action box, and tap on ezPDF Reader.

Alternatively, you can try uninstalling and re-installing the ezPDF Reader app.  It should re-register its own intent for handling PDFs, and prompt you for an app next time you try to view one.

There is an app for that !! Try Default App Manager on the Android Market which can take care of both clearing and setting defaults for various categories like pictures, audio, video, pdf etc. Really makes life very easy.


In which version of Android was encryption of /data made available? These docs suggest that it has been available (only) since Android 3.0 Honeycomb. By contrast, conversation on discussion boards suggests it was available in 2.3.4 Gingerbread.

So, what is the answer to the titular question?

Bonus points if your answer clarifies the following. Are the official docs misleading? Or were those Gingerbread devices instead released after Honeycomb, and loaded with some kind of backported encryption feature? Or were those Gingerbread devices instead loaded with some kind of encryption feature added by the device manufacturers, that wasn't part of Android? In short, what gives?

Gingerbread 2.3.4 ROM added support for device encryption, but the feature wasn't accessible from settings until Honeycomb (tablets) and ICS (smartphones).

To enable device encryption in Gingerbread device, you need to add an Exchange account. Not sure, but it should be accessible through API too.

There are also some hacks to enable device encryption directly in Gingerbread: http://forum.xda-developers.com/showthread.php?t=1405165

Encryption is certainly something that was introduced with Honeycomb on tables, and ICS on phones.

There was no encryption for Gingerbread.  At least nothing that was released.


How to avoid expensive roaming fees when going abroad with my Android? Usually I like to bring my Android phone with me when going abroad. But I use it very carefully because I know that it is very expensive to consume data traffic and roaming fees, when I'm abroad.

How do I best use my Android without getting expensive bills when coming home again?

Is there any specific settings that I should do? Any good applications or other tips that can be useful when going abroad?

Go to: Settings > Wireless & networks > Mobile networks.

Make sure the "Data roaming" checkbox is unchecked. That will keep you from roaming accidentally, since you will have to enable it.

If you want to enable it and use roaming lightly, there are some apps in the Market that will track your data usage for you.

However, in my experience roaming abroad has been so expensive that even roaming for a few minutes of data is not worth it. I usually either try to find a public hotspot or get a prepaid SIM card with data.

I realize this is a commercial plug, but I'm merely a happy customer, not part of the business ... anyway, I rented a SIM card from http://iphonetrip.com, and got data while travelling in Mexico (I live in the US).  It worked well!


how do I set up adb with MyTouch 4g? I have a mytouch 4g running gingerbread.  I want to set up adb to work with the phone over usb, but I can' figure out how to do it.  Frankly, I don't really know anything more so I'm not sure what else to say.  Any help is greatly appreciated

First, ensure that "USB debugging" option is enabled on your phone by going to Menu -> Settings -> Applications -> Development.  On some devices this option will be grayed out while your phone is connected via USB, so disconnect it first.

Next step is installing the USB drivers on your computer.  Assuming you are running Windows, the drivers for MyTouch 4G should be located on the SD Card that came with the phone.  Look for file named "HTCDriver.exe" then copy to your PC and execute it.  If you can't find that file, look for the drivers on Google.

After you successfully install the drivers, download and install the Android SDK.  Pick a folder that's easy to type, such as "C:\AndroidSDK" for example.

Now open Windows Command prompt by going to Start -> Run, typing "cmd" (without quotes) and pressing Enter.  In the Command Prompt window type in cd C:\AndroidSDK\platform-tools and press Enter.  Connect your MT4G to the PC via USB, and in the command prompt type in adb devices and press Enter.

If everything was correctly installed you should see messages like these:

  * daemon not running. starting it now on port 5037 *
  * daemon started successfully *
  List of devices attached
  XXXXXXXXXXX    device

where "XXXXXXXXXX" is a combination of letters and numbers, signifying your phone's ID.

This means ADB is seeing your phone, and you can now issue commands to it.

Try HTC Sync Manager

How do I change the terminal font? I notice a difference in the terminal font between two of my Android devices, specifically in terms of character coverage (in both cases it's the terminal shell of JuiceSSH).  How do I set the font that the terminal uses in Android?

I found two ways for changing font size in JuiceSSH.
Use Volume keys
The very first time you would've used JuiceSSH, you might have come across this brief tutorial:
(Click image to enlarge)

Use the Volume Up/Down keys to adjust the size of the font.

Traditional way (Settings)
On the default page of JuiceSSH, go to Settings → Font size → adjust it.

Use the Volume keys of your phone to adjust the font.

How can I check the OS version of an Android device? I just bought an Xperia x10. How can I check what version of Android it has?

Look at Settings -> About phone -> Firmware version (or similar).

Look at settings about device or phone or tablet, press android version again and again.  If it's Jelly Bean a jelly bean face will be shown, if it's KitKat a K will be shown.


Some of my apps disappeared after wiping cache and dalvic cache. Why? I am running Cyanogenmod 12.1 snapshot ROM on my Moto G 2nd gen. Today I Installed Xposed framework and Wiped dalvic and cache. After reboot I noticed that some of my apps have disappeared. Only grayed out icons can be seen. What should I do now?

As for as i know, when a rom boots up for a first time dalvik goes each and every apks and extract the dex (Android programs are compiled into .dex (Dalvik Executable) files) and put in the cache.So next time when you use your mobile it start faster and improved the performance, so when you wiped dalvik cache, it only clear cache memory. it will not delete application data.

i cannot say exactly one solution for your problem without getting more information, try to reinstall apk, maybe it will solve your problem because data is not deleted.


How do I set the default messaging app to use google voice? (4.2.2 Galaxy S4) I keep seeing advice to set the default messaging app by going to Settings> Manage Applications> All Applications>

And then clicking on the messaging app (I also tried google hangouts since that can send text messages).  But in the "clear defaults" button is greyed out and it says there is no default.  If there is no default, then what is it using to send the message?

I guess a second-best solution is for me to replace the default app with one that can send using google voice.

I believe this is the app that can solve your problem...

How can I make new/separate folders in the gallery? I recently had some issues with my LG Marquee and had to copy the SD Card's contents to my PC, then put those contents onto a new SD Card to salvage my media content(photos, videos, apps, etc.) When I inserted the new SD Card with my content on it, my phone took the content but it all (all 3,548 items) were placed into one single folder in my Gallery.

My question is: How can I separate/organize these items into new and separate folders in the Gallery?

Is there a specific way on my phone that I can do this, or do I need to download a photo organizing app? If so, what photo organizing apps are safe and secure?

Thank You!

My work-around is connect my phone via USB mode, where it comes up as a folder (or volume for you Mac fans) that you can see contents in. Create folders you'd like to have in your gallery, like "Favorite Piks" or "Stuff I found in my pockets" - whatever. Put these in that folder.
Now use your computer to organize the images between folders within that main volume, save on your home computer, delete, so forth.
When you detach from the USB link, your gallery on the phone should show those new folders you created and the images you transferred over.
Please note that any NEW images, photos you download or take with the phone will likely be placed in one of any generic folders like "Downloads" or "Pictures".
t0mm13b's Edit
Pre-requisites:

ADB is installed.
comfortable with Command line.

By going onto the command line, and issue this command:
adb shell am start -n com.android.development/.MediaScannerActivity
The above command line will force Android to re-read the SDCard and quickly re-index all the just transferred pictures into the Gallery.


Why does it take so long for a program like Mapdroid to use the GPS to track you on a map I was in London last week (which is outside my country, so I did not use roaming to connect to the internet to be able to use the maps application from Google). In stead , I used Mapdroid to find my way around the center there.

Mapdroid, for those who don't know this program, lets you download maps and than use them without data connection. The only thing you need to do is turn on the GPS.

This works great apart for the fact that it can take between 5 and 10 minutes for the program to mark you location. If it does, it can track you fine , and it keeps tracking you on the map.

But I am just wondering why it takes so long before Mapdroid knows where you are.

Is it a hardware thing (I have a Samsung Galaxy S phone running Froyo).

This shows the difference between AGPS and GPS. AGPS (Assisted GPS) uses a small amount of mobile data to establish a rough location fix (about 1km-100m accuracy) based on the cell towers near you. This gives a faster initial location fix than just GPS. Since you had roaming disabled, AGPS wasn't available and getting a location fix on just GPS can take a while, especially on some firmware versions of the Galaxy S.

Galaxy S has a notoriously bad GPS. I Changed from S to now S3, and there is a HUGE difference. The S3 is extremely fast to get a GPS lock, and incomparably more precise. So don't expect wonders from a Galaxy S.


Does a carrier know I am tethering via Wifi Hotspot? I am using my phone's built in Wifi Hotspot to share wifi with my laptop and my other devices.  I am using android 2.3 (Gingerbread), and the phone I have is the HTC Desire Z.

Questions

Is it possible for a carrier to detect that I am using "Wifi Hotspot" and sharing my mobile data connection with other devices?

Furthermore, is Wifi Hotspot a feature that most android devices have? and is it a feature that can be disabled by the carrier (on a phone-by-phone basis)?

It is not detectable, but using tethering on Android with an second device leaves a lot of traces:

User-Agent Headers within HTTP that come from non-mobile browser
Increased Traffic consumption
Connection to services that are not available on Android/Smartphone devices (e.g. World of Warcraft)

and many more I can't think of atm.

But I have never heard of a carrier that goes for a trial, even if it's a violation of services from most carrier contracts. IMHO Mobile carriers have other problems at the moment, like overall increased mobile data traffic because of the smartphone boom. These is currently handled by soft limits of data traffic, that when reached only allow traffic over 2G connections.
Or, to answer your second question, if you buy a smartphone from some carriers, the build in tethering function is locked and not usable.

Maybe I'm wrong on this, but I thought tethering worked by setting up NAT traversal and forwarding packets from your tethered device through your mobile device. This would leave a trace in the IP packets since the NATed ports need to be embedded in the communication for NAT to work. Since your IP packets aren't encrypted the carrier should easily be able to determine if you're tethering just by observing your data stream.


Magnify (zoom) part of image application I'd like to edit an image to add a "magnifying glass" ring with a magnified region inside, like in the screenshot below. The standard Gallery editing tools can't do that, and I've tried a few other apps with the same result. Is there any way to add this effect (zoom certain part of image) using any kind of Android app?


How can data on an unrooted phone be backed up? What methods are available to back up data (both system and application) from a phone which is not rooted and is running stock Android 2.3.4 Gingerbread?

It is my understanding that it is impossible to retrieve application data (not stored on the SD card) on an unrooted phone, except where the application itself offers export. Is this accurate?
Of the system settings and built-in applications, which ones have export facilities I can take advantage of? Which ones notably have no export and have significant amounts of data which I might want to manually transcribe out?

I am already using Missing Sync for Android which takes care of the contacts, calendar, photos, call log, and SMS messages. My phone is a Nexus One.

If a phone is not rooted that means that apps are securely sandboxed. There is no way that one app can access the data held by another app. In the underlying linux filesystem they are actually represented as different users, and do not have permission to access each others' files.

The only things that can backup the files are a) the system itself and b) the app can backup it's own files.

In Froyo (2.2) Google introduced cloud backup, which many app developers have integrated into their apps. This means than some apps will just automatically restore their data as soon as you sign into a new phone with your Google account. However, this will only work for those apps that have implemented this functionality.

You should find that all of the system apps now have full backup, or cloud sync, from Froyo onwards.

From my recent experience upgrading to a Galaxy Nexus - Cloud Sync: GMail, Calendar, Contacts; Cloud Backup: All system settings (I was surprised by some), Email settings. Not backed up: Browser bookmarks (though these are synced in ICS).

There is not default system functionality in Vanilla android that will backup all of your apps, and I'm not aware of any operator/manufacturer customisations which have implemented a system-level backup.

One thing that you can do is to install a new recovery, such as ClockworkMod. This does not require your phone to be 'rooted', however, it does need you to have an unlocked bootloader, which I suspect is what you are trying to avoid, as it is typically reflashing the bootloader where 'bricking' occurs.

You may be able to manually pull all of the files from the /data partition, using adb. You can browse them using 'adb shell', and pull them individually using 'adb pull', but you would need root to be able to restore them. This also requires a certain amount of technical understanding. edit: actually after further testing, even this requires root access.

The suggested MyBackupPro below will not backup all of your apps - only those with exposed contentResolvers (ie SMS, calendar, contacts etc). Those things are automatically backed up in Gingerbread anyway. (I can't comment or vote down)

ASTRO File Manager is great to backup apps as well as many other features that make it an overall great app itself. I have used to for backup when I have needed to wipe my phone and start again.


Sony Emma FlashTool saying Unable to connect to the network and exits suddenly while I have network When I'm running sony flash tool (Emma) it shows me following error and suddenly exits:

  Unable to connect to the network, please check your network connection.

But I have a connected internet and checked firewall not blocking emma. Why showing this error? I need this tormentor emma flash tool to install an official stock rom in FTF format. On my experience emma flash tool is very weak in design and stops woking with strange and non-described error messages. Are there any alternatives to do same thing without any kind of torturing? Previously, I used odin for my other Samsung smartphone and it was doing its jobs much better.

try updating your JAVA. It might work...
If you Want to fash a new Rom, 'Flashtool for sony' will be very useful. It is very easy to Use.


Uninstalling 360 Security I'm trying to delete 360 Security from my phone ( Samsung J 6 3 ), and it is activated as my device Administrator, when I go to deactivate the device administrative permission it shuts down my settings. How can i get rid of this app?

Try to repeat this step in safe mode. You can access safe mode by these steps.

  Power off your device by holding down the Power button and then tapping on Power off.
  Power on your device by holding down the Power button. As soon as the Samsung Logo pops up, press and hold down the Volume Down key until your device as rebooted.
  You will now be able to see Safe Mode down the near the bottom left of the screen.
  To exit safe mode just reboot the device.

Hope it helped.

Funny things happen .I updated the 360 security app and then went back and the device administrator was deactivated .don't ask me why but it seemed to help .Thanks everyone for you answers.


App says its uninstalled but I can't reinstall it I downloaded minecraft from the Amazon appstore and installed it to my sd card. My brother removed my sd card, formatted it, and put it back in as a prank. Minecraft said it was still installed, so I uninstalled it. I tried to reinstall it through the Amazon appstore, but the only option was to open the app, which didn't exist. I waited for an update to roll out and clicked the update button. Every time I do this, as soon as i click update the Amazon app crashes. I've checked in the apps section in settings, I've uninstalled and reinstalled Amazon appstore, and I've even tried clearing the data of the app. None of this works.

Try through cmd line

adb install -r yourapp.apk


Where does Google Play Music v5 store music locally? I know this question has been answered for older versions of the app, but where does the most recent app store offline music?

Clearly the mp3's I've selected are downloaded - because they play without an internet connection. But the default location for offline music is empty.

Any ideas guys?

My Google Music 5.3.1317M.940995 running on a Nexus 4 with CM11 stores the mp3 files under

  /data/data/com.google.android.music/files/music

You need root to access that directory.

A older version of Google Music on a Galaxy S stored it on the SD card. And, as I read in the official changelog, Google Music 5.x seems to be able to use the SD card as storage too. Which makes sense for devices with low internal storage space (/data/data).

If you have a lot of patience and a little bit of *unix wisdom this shouldn't too hard for you. Just open up a shell or connect using adb and try:

become root:

su

search for the song:

find / -name "*.mp3"


How to turn off Yahoo Mail notifications in 4.1.2.? I just upgraded my Android OS to 4.1.2. and the Yahoo Mail is pushing audible notifications again (I had disabled them in the previous version of OS).  When I go into the app, there is no settings in the menu.  How do I disable the notifications?

When such a notification appears...

Open your notification area
Long-press on the notification. This opens the app's settings in the system configuration.
Here you can disable all notifications from the app.

This is a feature introduced with JellyBean -- as you've stated your device is running Android 4.1.2, this setting should be available to you.

You can remove your yahoo account from your android phone. Just go to settings - > Account & Sync  - > Serlect Account and the you will find the option to delete the account.


How do I get rid of "System Data" that takes up half my hard drive? So since I updated my phone, there seems to be a mysterious 3-4GB of "System Data" on my phone's hard drive that I can't get rid of.
Here are some screenshots of this:

I have an LG Leon running Android version 5.1.1

Is this a known issue with updating Android or is this a new thing?

After reading the question again and looking at screenshot this may be reffering to the System data stored on your /data partition.  If you can tap that entry and see if it gives you any more details as to what it is reffering to.  This probably contains the OTA update in full (along with other settings as well).  So you could possibly drill down inside of the system data option to see what is all there.  an Update Zip is going to be rather large (for android and mobile device files anyways) on the order of 300-400 MB + (depending what is all in it).  You would be safe to delete the OTA files since they are no longer used after the update is installed, BUT AGAIN A WARNING...  This System Data Items Entry is probably reffering to a lot more than just the OTA download itself I would not just delete that entry I would instead go in to it for detail, and if none is given there then use something like ES File Explorer (once open in app settings>view check the box for showing hidden files) and go looking in /sdcard/ for a directory containing most likely a zip or a couple zips (may be separate zips for the ROM, Recovery, Fastboot, Radio, etc. depending on your device and manufacturer and how they handle things).

Reminder: as long as your google account is syncing correctly all your app data (not all apps but the majority have this enabled) along with your contacts (and even pictures if you set that up) are all sync'd back to Google so even if you delete this whole directory and have issues and have to do a factory restore and wipe all data when the phone starts up and you login again it will re-download all that data for you.  Just be sure to go in to system settings>Accounts and tap google and tap the entry for your account and make sure every box is checked (is OK if browser data has ! and you see a chrome entry there your OEM browser is failing to sync but Chrome is not and has everything)  Also can uncheck items if you don't care whether the data is backed up or not (like Google Fit LoL).  I will still leave the original answer below as others may find the info useful.

The system partition by default is not accessible to the user.  NOW that is not to say it forgot to clean up behind itself if you did an OTA update.  Without rooting your phone the only way to probably adjust this is to grab a factory zip from LG for your device and flash it using their instructions.  This will remove everything in system and do a fresh install.  You are right though it should not be anywhere near that size.

BUT BUT BUT

If you are not using a rooted device you will never be able to write anything to that /System mount point so as long as the phone works it really does not matter if that partition is maxed out it will never be written to anyway.  If you don't notice other little issues, and are happy with the phone I would just use it as is.  Even if you have root again you will not be placing anything in /system (if you do it will be one or 2 tiny things mostly).

/system does NOT affect /Data so no matter how much storage your /system uses it will never take away from nor add to the storage space in /data.

For instance even if you update a google app that is installed in /System Android actually installs the update to /Data and stops using the version in /System (while still leaving it there untouched in case you go to Settings>Apps> and tap Uninstall updates.  If you do this it removes everything for the app in /data and begins to use the copy in /system until the next update).

Basically, Android writes things to System during SYSTEM install (and that only really happens through the recovery menu not the actual Android OS itself (the recovery menu can actually be thought of as a second tiny OS that lives inside your device alongside the full larger Android OS kinda) and after that everything gets stored on /data and nothing gets written to /System only read from (it's a security thing if the system can write to /system so could say a virus which would be a bad thing).

That is probably a bunch of stuff you should not remove. For example it could contain the Android OS file images that are mounted during start up for your different directories: /system, /data , /sys, etc. These are things that are vital to your phone running, and thus removing them is a bad idea.


Dialog option "Use by default for this action" or "Always" not displaying I just completed my Android application which scans NFC tags. When an NFC tag comes near the device, the device tries to show all the apps which can scan the NFC tag.

I want it to remember which app it should use scan the NFC tag. It displayed my app, but I do not want the system to always ask me which app to use.

In my two devices, it not does show any option like Use by default for this action or Always. Why is this so?

This is because there can be no default handler for all NFC intents. You'd have to create a mimetype for your NFC tag and use that mimetype as the data field for the intent filter.

However, this site doesn't deal with developer issues, so you'd be better off on StackExchange, for example here.

Someone, or something has set defaults for the application(s), and this default was set as soon as someone or something set it by either internally, or by hitting the button "Always.", in this case you'll have to go to your App Drawer, go into Settings and find your Application Manager. In this case, you'll want to go to the application that doesn't have the option. Find it, click it, go down and hit "Clear Defaults.", now, hit the home button, find the application you're wanting to run and VOILA! The action menu should set itself back. If it doesn't, find the application that is automatically running upon startup of that specific object, and hit clear defaults.

Thank-you,

How do I get rid of mysterious stuff displayed on my cellular's screen? There is tiny writing listing currently running systems and a red frame around my screen and a white dot wherever I touch the screen and a thin white and red line blocking my notification bar with writing that looks like stock market listings.  How do I get rid of all these items?

You most likely switched on several feedback settings in Settings→Developer Options:

Developer Options (Source: AndroidAdvices.Com)

In these screenshots the reason for the "white dot" wherever you touch the screen is already marked. Additionally, you probably have enabled "Show CPU usage" as well (right screenshot, lower third). Just turn everything off here which you don't know what it's for; by default, nothing is checked in this menu.

Settings → Developer options → Uncheck Show layout boundaries.


How can I change the default Google Drive PDF viewer on Android? I've been used to downloading PDFs on my phone and have them directly saved on my downloads folder. But just recently, whenever I download PDFs, Google Drive viewer shows up. I know there's a download option on Google Drive viewer. But when I open the file, it prompts that there's no app that can read it. I have Acrobat and Drive that I used to read PDFs with.

I think from some of the research I did, the update for Google Drive makes it the default for opening PDFs. I checked the defaults, it did not have one. I just uninstalled the update for Google Drive as a temporary solution.

I think I changed the defaults by accident (I did not assign one before). How do I change that, if ever?

My phone's a Samsung S5. I'm using Chrome for it.

I had the same problem using Firefox on Android - totally maddening - but fixed it.

After installing Google Drive all my links to pdfs would open with Google Drive PDF Viewer.

I fixed it by, in Firefox, going to about:config in the location bar, then finding "browser.download.preferred.application/pdf" and doing a Reset there.

The next time I clicked on a link to a pdf I got the choice to Download, or use Google Drive PDF Viewer.

Shouldn't it be there in Chrome, under the hood somewhere ?

Btw, that "browser.download.preferred.application/pdf" in Firefox only seems to show up after a choice has been made, in this case, forced by the install of Google Drive. Seems redolent of the old browsers wars.

I too was struck with this issue.  Google drive hijacks the downloads, and then Adobe wants 9.99 per month ransom to get them out of there.

Uninstalling any Google Drive updates and then disabling it will also solve the problem...and without having to give up other advantages of the chrome browser.


Are Google Photos' high-quality pictures compressed even if they're under 16 megapixels? Recently, Google has changed the Google Photos app so that everyone has free and unlimited access to store 16 megapixel files.

The camera on my phone is under 16 megapixels. When I downloaded the app, it asked me whether I wanted to keep the photos in original or high quality.

I would like to take advantage of the free storage so my question is if the photos are originally less than 16 megapixels, is high quality going to be the same as original or would Google compress it more?

Also, what happens to the existing photos on my Google Drive that are less than 16 megapixels? Are they automatically not counted toward my quota or do I need to somehow migrate them to Google Photos? Just that, the majority of the files on my Drive are photos (which are less than 16 megapixels) and since I've downloaded Photos, the space available has not changed.

I just took a picture with my phone (8MP) after configuring auto backup with both Google Photos (with "high quality" option enabled) and Dropbox.

I compared both images and I can't see a difference between them, although the file sizes differ (the image in Google Photos has 1.3 MB and the one in Dropbox has 2.2 MB). I made the same comparison with an older image (when I had the "original" option enabled in Google Photos), and the files are exactly the same.

Seems like Google is really compressing the file, although keeping the image quality.

Google in I/O have said that the photos which are less than 16MP will not be compressed and the ones above the 16MP are the only ones which if chosen to be stored under the "unlimited storage" space will be compressed.

Also from my experience I've not seen any change in my drive storage after the new "unlimited storage" option. So it should only mean that the present ones would stay the same.


How do I enter recovery mode on my Motorola Milestone 2 to unbrick it? I own a Motorola Milestone 2, also called A953 (apparently this is different from the Droid 2 Global). It used to have Android 2.3 with Motoblur middleware. It was bought independently from any phone carrier (so it was not bought from Verizon for instance). I rooted it, installed ROM Manager, Droid 2 Global Recovery Bootstrap and ClockworkMod Recovery. From ROM Manager, I could successfully reboot my phone into Recovery mode, allowing me to back-up my data for instance. Until this stage everything went fine.

What lead to my problem : I also wiped the cache and installed CyanogenMod 7.2 and the Google apps from ZIP files and from the Recovery Mode interface. But now my phone is broken. When it now boots, it shows the stylised M logo, but then switches to an entire black screen. The phone is still on so I have to pull the battery to shut it down.

I would like to reboot into Recovery Mode but this doesn't work : I am never able to see the Recovery Mode logo (a warning sign with a little android). How should I do it ?

What I have tried : I tried to boot while holding the Power and the 'X' button, as adviced on different forums. This still leads to the black screen. At this state, pressing the Search hardware button does nothing. Holding the Power and the Volume Up button has no more effect.
I am able to enter Bootloader Mode by holding Power and Up Arrow.

I also tried to use a live CD from here with ezSBF, but I get errors in the process and then my phone reboots in Bootloader mode and shows the following error:

Critical Error:
FEBE 0047

After that I still cannot get to Recovery Mode.

Is it unplugged when trying to do this?  I could hold X while booting, then I would see the Android and exclamation.  Then hold Up/Down Volume and get the recovery. You have to press both Up & Down at the same time. It is not a rocker key and you can press them both. Use Enter key on keypad with the arrow above OK to make a selection.

Power up while holding the X and when you see the yellow exclamation mark after the Moto Logo, hold Vol Up+Down. That should get you to the Recovery Screen.


How can I permanently disable USB debugging mode? I have a Samsung Galaxy Ace and I've encountered a strange issue. When I was connecting my mobile to the PC I unchecked the box for "USB debugging mode" and did my work without issue. However, after some time passed and I again tried to connect my mobile to same PC, it was unable to connect. When I checked my settings, I noticed that USB debugging had become re-enabled again. Is there anything I need to set to disable USB debugging permanently, or is this the default behaviour of the Samsung Ace?

This happens to myself, you would have to turn the device off several times whilst your USB is connected and just wait for it to stay turned off, once its turned off it will not turn back on unless upon reconnection. It's a very old phone and is not a good phone so this is why it's like this. I wish there was a better resolution myself but after browsing the internet for around an hour I figured I'd help a somebody else and let them know what I know.

Thanks.

It's possible that one of these solutions will help you

Solution #1:
If you do not have drivers for your phone installed and you do not want to download huge KIES, you can download only the ADB Interface Drivers (6.5mb) for your phone. This might solve the issue about USB Debugging turning itself on.

Solution #2: Download and install Terminal Emulator, open it and run the following code inside.

adb kill-server

this might also help until you reboot your phone.

Why is Youtube draining the battery and what could we do? A friend of mine just asked me a nice question:

His (stock) Samsung Galaxy S4's Youtube is draining his battery.
He said, that he hasn't been in the app today, and this morning he had the phone booting up.

Now, Youtube drained 51% of his battery.

I know, there are many possibilities, to "solve" this, like:

Rebooting the Phone to get rid of the wakelock
Terminating the Youtube-app via the Settings -> Apps menue
Clearing Cache/Deleting Data
Uninstalling Updates and deactivating the app

But besides these workarounds:

Is there any fix for this issue?

What could one do, if he'd have to terminate the app everytimes he boots up his phone?

Is there even something to do?

/NOTE

We try to achieve a better information about what exactly in the YT-app causes the battery drain using Better Battery Stats.
Stats will follow.

Try to install Greenify.

  It helps you identify and put the misbehaving apps into hibernation
  when you are not using them, to stop them from lagging your device and
  leeching the battery

Greenify is a good application but the issue is that YouTube drain a lot of battery when you are watching videos and doing anything. I have seen in Greenify that background YouTube not drain battery; if you open it then it start draining battery battery.

So I think disable YouTube app and gets alternative that don't drain battery. for that I suggest NewPipe.


Force Google Maps to save cached maps on SD card I am downloading a large number of map areas in Google Map for offline use. It appears that, by default, Google Map writes its cache to my phone's relatively scarce internal memory. Is there a way to force Google Maps to use SD card instead?

I am using Google Maps 6.7.0 (latest version as of May 2012) on Android 2.3.3.

Update to Maps 6.9.0 (released 2012-06-27) or later if you not already have done so. Google added the feature one you wanted:

  What's in this version:
  * Save maps for use offline

Besides this: Cached tiles for Google Maps are saved to the SD card.

To also answer your exact question (for users that cannot upgrade):

Use Android's provided 'move to sdcard' mechanism or install some 3rd party apps to do it (Link2SD, App2SD skripts, most need a custom rom however).

If all above is not an option and you like to do it manually:

Prerequisites:

Root access
Know which directory you want to move
Be sure that directory doesn't contain executables
Awareness: /sdcard/ is world-readable and many apps can write to it.
You might not want to expose sensitive data to other apps
Be sure the app is not running.
If something breaks, you might fix it by clearing the appdata
The app might break if sdcard is not accessible (e.g. phone plugged into PC)

A. You need to find the package name of your desired app (just reverse the steps here, aka go to the Google Play website of the app and see the package name in the browser's URL, for Maps it's 'com.google.android.apps.maps').
The location for the app's internal data is then: /data/data/[PKG_NAME]

B. Find the big subdirectory that you want to move, use a terminal emulator or adb shell access to execute something like this on the device:

me@workstation:~$ adb shell
root@android:/ # cd /data/data/com.google.android.apps.maps
root@android:/data/data/com.google.android.apps.maps # du -sh *
8.5K    app_sslcache
9.0K    cache
55.0K   databases
52.0K   files
2.0K    lib
2.5K    shared_prefs

C. Move & symlink

mkdir -p /sdcard/Android/data/[PKG_NAME]/linked
mv /data/data/[PKG_NAME]/[BIG_DIR] /sdcard/Android/data/[PKG_NAME]/linked/[BIG_DIR]
ln -s /sdcard/Android/data/[PKG_NAME]/linked/[BIG_DIR] /data/data/[PKG_NAME]/[BIG_DIR]

You can use Root Browser or ES File Explorer. However, you need a rooted device to access root directory.


Unable to disable password on Android screen lock I would like to disable the PIN/Password of my Android screen lock but I am unable to  do that as the relevant option is greyed out. Please see screenshot:

(Click image to enlarge)

Please read the subtitle of every remaining button...

"Because you've turned on an accessibility service, your device won't use your screen lock to enhance data encryption."

You need to turn off accessibility services before you can change any settings here.

Settings-> System section-> Accessibility->
Turn off each process using the accessability services until you are allowed to change your password again.

A second cause may be what Journeyman said, but you seem to be running an older android version that doesn't support that.

Go to settings - fingerprint and password - smart lock - on body detection - turn it off


Sharing files between users in 4.2.1 I have a Google Nexus 7, unrooted, running stock 4.2.1. I have set it up for two user and we seems to be enjoying it.

Recently I ran into an issue about sharing files. In User1's account I copied few PDFs into \sdcard\PDFs folder and was able to use it well.

When I switched to User2's account, I could not see the folder \sdcard\PDFs at all. Surprisingly, I could not see it even when through computer when Nexus 7 is connected as Portable media player.

I guess this can be achieved by granting sufficient access by escalating to root, which needs rooted device - but I am not sure.

My questions:

Are there any way I can share files between users of the same tablet without using Internet (like using email, dropbox etc) or transferring to some repository like PC etc?
If I root, can I change the permission to such user created folders and access files from other user's account or elevating as root?

Update: Found a link that asks same question - but the answer given is not applicable for files rather works for apps, not useful.

After a lot of trial and error, I  discovered that the Android/obb folder is automatically shared among users.

It's not ideal, but it's better than a cloud storage option for large files.

Run Paw server on user 1
Use the built-in file manager


K-9 Mail not working with Openkeychain K-9 does not seem to find the installed Openkeychain app. OKC works fine and so does K-9 except for this problem. Both programs have been installed from F-Droid and are the the latest version. I am using a Moto G ("falcon") with ParanoidAndroid 4.6b5 without Gapps. APG used to work.

Thanks in advance for any help.

Apparently on the "Accounts" screen, one has to long press the account.  Menu will pop up.  Click on "Account settings".  Another menu will pop up.  Click on the "Cryptography" item at the bottom.  The Cryptography menu will open.  Click on "OpenPGP Provider".  By default, "None" is selected.  Click on the "OpenKeychain" and you're set!

Hope this helps!

I finally found an answer. There is a setting in K-9 to use any encryption app installed.


Oppo Neo 5 (2015) Stuck at Logo Screen So I rooted my phone successfully. Then after that, I installed Flashify to Flash CWM Based Recovery and shows "copying file to ....". After that it reboots to recovery and now it is just showing me the Oppo logo screen. I can't access the recovery even I press the key combination. Yes it shows ">>> Recovery Mode" but it is just stuck on the logo. Please anyone help !?

Here are some Info

Android 5.0.1
I have the stock ROM for my device

I also have a problem when I charge my phone, it automatically goes to recovery but still stuck at the logo screen

It looks like you flashed a recovery that didn't support your device. Good news is since your rooted, you can unbrick your phone by obtaining your original rom.

If you didn't back up your rom/recovery, then you will need to download your STOCK rom off the internet and flash it via Odin.

Odin is a popular flashing tool for windows and mac. It works better on Windows.

ALSO, when flashing with odin, you will need a pit file. Pit file tells Odin where to correctly install the rom.

If your not familiar with flashing using odin, I recommend you look it up.

I hope this helps!


Why is rooting considered dangerous? I understand that being root, applications can do a lot more with your device, but an application first needs root access, so what is the problem? By that logic, Linux as a whole is a dangerous environment since you can give root access to commands by using "sudo". Wouldn't it be more correct to say that root access is as dangerous as the user? If the user is stupid and gives root access to all applications, then yes it is dangerous, but stupidity of users will always be present in the IT. field.

If you know what you give root access to, in what way is rooting your device more dangerous than not rooting?

Why is rooting considered dangerous

Because when you root your phone you have (basically) full access to your phone, if you accidentally delete a system file/application it can brick your phone & you have no way to get your files back unless, of course you have the stock firmware downloaded & restore your phone using Odin.


How does power usage for data over WiFi compare to data over 3G? (Ignore LTE for now) If you have unlimited data over 3G so that cost is no option, which is more power efficient?

Using the WiFi or 3G connection for data usage?

Extending battery life being the goal

I never really did a precise comparative test but it is clear that wifi uses way less power than the 3G data connection. So I would recommend to use wifi whenever possible if the goal is to extend battery life.

The only exception I would see is if you often use the phone but for a very short moment at a time, the delay it takes for the wifi to connect can be a hassle. In this case only I would deactivate the wifi.

this is subjective my friends.. no exact answer. is definite answer.

scenario 1 - you have a good wifi reception - phone dont have to try hard to fetch network, so battery life is longer. but if wifi is tough to connect then offcourse the phone needs to work hard.. so battery drain quicker.

scenario 2 - you using data network, but in bad reception area then it would have same affect on your battery - drained faster..

in the end, depend on your area's connection in order to have longer battery life..
who knows which connection is the best in tht particular area. just simple logic. no technical wonders can save your battery life i say..


How to change SD Card after moving apps using link2sd I haven't used link2sd yet to move apps, because there is one thing I'm confused about. Currently i have a 2 GB SD card on my phone, but I'm thinking to buy another 8 GB card later.
What will i have to do if i want to transfer all the apps (linked/moved using link2sd) to my new 8 GB SD card?

I tried copying the SD card to a folder and then to the new card. I used Linux Mint 17 running Nemo as root. If you don't have Linux installed, I would recommend a Kali Live disc, since it runs as root. Everything seems to have copied but the first boot of the phone gave me an inconsistent UID message. It was gone at second boot. Some apps worked, some worked after reinstalling, and others lost all of their data. If you try this, move the stuff you really don't want to lose back to the phone. Starting a game all over again when you were at level 200 really bites. Facebook and Messenger store everything on servers so they could be easily reinstalled

Bro,don't worry!
when you want to change your sd card from 2gb to 8gb you shoud have two partation on 8gb'sd card.
now first of all uninstall all of your unsystemly apps and open link 2 sd.
now select clean up sd partation 2 and then select clenup partation's devilk-cache.
Now you can insert new sd card and enjoy these fetures without any issue.
                                                                              By mohit raj sarawata.


Does anyone have experience wireshark running on Samsung Galaxy Tab? (Verizon) I need to get detailed request data times on Samsung Galaxy Tab on Verison network.  Does anyone know what is invovled in getting Shark to run on this device?

I run tcpdump command on my rooted Galaxy tab and capture the output onto SD card. When I have captured enough, I pull the captured file from phone onto a Linux box using adb pull  and view the output using Wireshark.

I know how to do it.. With "Linux Installer" software you can install chrooted debian. Then I had to re-build my libpcap and wireshark on GTab because my Overcome kernel did support mmapped packet ring buffer.

I can give detailed instructions if anyone needs...

Oh, I forgot about X11.. You'll have to start X11 vncserver inside chrooted debian on your Android, and then connect to 127.0.0.1 from your Android with your favourite VNC client in order to access "X11".. Let's call this approach X11.99_pre_alpha_8 ))


Sync _all_ music in Google Play Music to local storage This might sound a little crazy, but I'd like to sync my entire Google Play Music collection to my external SD card on my Galaxy S5. Is there a setting in Google Play Music which will sync everything? I know I can specify where I'd like things to go, but is there a global sync all setting?

If I have well understood your question, I will recommend you to have a look at this question where I have explained how to do what you want : sync your music on your local storage.

I just found a solution that is not so clean but works. Using the web interface, in the tag where there are all your songs you can select packs of them using shift-click an add them to a play list.(you have to do groups of 1000 songs because is the maximum) then you have a free play list containing all your library is easy to sync in your phone.


Sony Xperia Z1 status bar issue I have a Sony Xperia Z1 that suddenly decided not to react when I pull down the status bar.

I restarted my mobile and also tried to use the developer options to show touches, but it still didn't work.

When using the developer options on Nexus 4, the Y coordinate changes from 0 to over 1k. On Xperia Z1, the Y starts from 87 and then moves as it should be downwards.

Aka. the touches over the status bar is not registered in the device... Any idea why?

This suddenly solved itself :

What i did is to enable developer settings and suddenly it started working after about 10 minutes.

Just install from "play store" the free application "DropDownStusBar", it worked for me.


How to VPN only a single application? Say you only want to route the traffic of a single application through a VPN.

(Because the application lacks proper encryption support or the remote service is only available on a cooperate network.)

Other stuff like web-browsing should go through the normal data connection.

How to configure this on a recent Android device (>= Android 4.0)?

Concrete motivation: Unfortunately, quite a few VoIP gateway providers do not provide encryption of data (voice and signaling) - thus using a VPN is necessary (at least when connected via WLAN). One provider (sipgate.de) even provides its own VPN (and no other SIP/RTP encryption methods).

The free and open-source OpenVPN for Android app supports this.

In the profile configuration dialog, there is an 'allowed apps' tab that allows you to select a list of apps that is either excluded or excluded from using the established VPN:

'VPN is used for all apps but exclude selected'
'VPN is used for only for selected apps' (sic)

The list then contains all available apps that can be selected/deselected.

This doesn't require a rooted device. For example, it works fine on a Nexus 5x device with stock Android 8.1.

A simple test is to install another broswer like Firefox, include just one of Chrome and Firefox in the list and then switch around browsers and visit https://wtfismyip.com in both.

One pitfall is when you are on a dual-stack IPv4+IPv6 network but the VPN is IPv4 only. In that case, the 'Bypass VPN for local networks' in the 'Routing' tab needs to be disabled. Otherwise, IPv6 traffic travels unencrypted besides the VPN.

Try using the older Hola Better Internet not Hola Free VPN it gives you the right to select the only apps for VPN services.


Daydream goes to standby when touched My Nexus 4 runs Android 4.4 and is set to use the standard "Clock" daydream while charging. It has no screen lock. This works fine so far.

Expected:
I would expect the screen to wake up when I touch the daydreaming screen.

Problem:
Sometimes the screen turns off when I touch it, rather than waking up.

Symptoms:
There might be a time element because this seems to happen when I have not touched the phone for many minutes, but it seems to work OK if it had only been daydreaming a few minutes. AC or USB charging does not seem to make any difference.

→ Why does the screen turn off instead of waking up, and how can I "fix" that?

I had this problem some time ago. It went away after i flashed kitkat as i didn'twant to wait for OTA update.

Try rebooting or write what you already did to try solve the problem


Do all android phones store videos with rotational metadata? Do all android phones store videos with rotational metadata?
For example, I just recorded a video on my 'phone', holding it in portrait, and using the front-facing camera (used the front facing camera so I can easily see what I am recording, with me on the same side of the 'phone' as what I am recording).
C:\blah>mediainfo VID_20210106_215520866.mp4
.....
Rotation                                 : 90°
....
C:\blah>

There's rotational metadata there so instructing video players to rotate it 90 degrees clockwise for it to be oriented the right way up.
I'd rather a phone that records it the right way without rotational metadata.. so I was wondering if it was phone specific or something to do with Android.
I thought the problem may be unique to my Moto G7 Power, as I asked somebody else that had the same 'phone' and they claimed that they didn't have that with theirs(though I doubt their claim).  Then I got another 'phone', an Oppo. And it too did the same thing.
I then ran into this webpage which suggests that it's actually an Android feature.
Do all Android phones place rotational metadata on videos they record with 'phone' in portrait position?
While I normally get that so eg if it were recording a person, then their feet on the right, their head on the left.(hence 90 degrees clockwise rotation required), funnily enough i've also had videos come out oriented 90 degrees the other way and so have rotational metadata of 270 degrees e.g. if it were recording me then my feet on the left my head on the right, requiring and having metadata instructing 270 degrees clockwise  / 90 degrees anti-clockwise rotation.

Videos recorded using mobile devices contain a lot of metadata.
One piece of such data is the rotation metadata.
This data is used by browsers such as Chrome and Safari and by video players like VLC and QuickTime to display the video the way it was shot: portrait or landscape.
The rotation metadata is stored as an integer, it represents degrees, and has 4 possible values: 0, 90, 180 and 270. Here are the values for each device orientation for both iOS and Android:


Trying to root and install Xposed on Nexus 5 with Lollipop I'm trying to install Xposed on my Nexus 5 running 5.0.1. I used Wug's rootkit on Windows to root my device, but first of all it seems that I cannot root. I have gone through the whole process listed on the XDA page. And everything the root kit itself walks me through.

I don't see SuperUser installed after my device reboots; I have done a second test to see if I'm rooted by going into the terminal on my device and checking the symbol after the prompt is a '#' instead of a '$'. It's a '$' currently, which I'm told indicates that I'm not rooted.

It's worth noting I suppose that my device is encrypted, but I don't think this would affect anything since the encryption function encrypts only the /data folder and not the /system folder.

Does someone know if there is an issue with 5.0.1 or perhaps something else I need to be aware of? I'm not sure why this doesn't work.

Hopefully I don't get burned too badly for this, but I thought I would share this info for people who haven't rooted/unlocked their phones lately (or never have).

In order to root one must unlock first; this functionality is provided in Wug's rootkit as well as the rooting function.

I was trying to mod my phone as little as possible, and I was told by several people that I could root without unlocking first, but it appears that this can never be done (perhaps Wug's rootkit should make that a pop up notification that the user must read in case a scenario presents itself where a user tries doing what I did; this way they can take recourse). In short, I had heard long ago that rooting and/or unlocking could potentially permanently disable Google Wallet, (more deeply speaking, I believe it would disable the use of the NFC chip) and I use NFC for lots of things so I didn't want to risk it if I didn't have to.

I've restored now, and everything has been tested and is fully functional.

Custom Launcher that supports Google Now integration? I just upgraded to a Nexus 5 and am setting up my launcher + icons.  Right now I'm using Nova Launcher, and a like a lot of things about it, but it's lacking in Google Now integration. Two things in particular I miss:

Having Google Now start listening when I say, "Okay Google" without pressing a button - this still works once I'm in Google Now, but not on the Nova Launcher homescreen (as it does with the stock launcher).
Being able to swipe over to the left from the homescreen to get the Now screen

Are there any launchers that support these features, especially the first one?

The Google Experience Launcher is actually built into the Google Search app along with Google Now. This is why it can listen for 'Okay Google' and have Google Now accessible via the left swipe. Ars Technica has a good article which goes into more details on this.

There are some launchers that support gestures, which might be similar to the left swipe to access the Google Now page (although they will only be able to launch Google Now in the same way an upward swipe does).

I don't think there are any that support saying 'Okay Google' from the homescreen though.

Theres an app called open mic+ its helps wid the ok google thing swiping left fr google now is no where present excpt GEL but i personally didnt like the interface the icon size ws looking big on my note 2 i prefer nova launcher wid open mic + .apk it works like a charm ;) plus whoever said it doesnt wrk whn screen is off ur wrong m using it and wrks wid locked screen and yes if u set it to start up on boot it strts frm boot ;)

I have a Sony Ericcson Mini Pro (Codename “Mango” at CyanogenMod) with CyanogenMod 9.1.0-mango. This is Android 4.0.4.
The problem
When trying to connect to a wireless network, it will be stuck in an “Optaining IP Address” loop for a while, until it shows “Bad Connection”. This is what it looks like in the wireless network system settings:

My tablet with CyanogenMod 10.2, Android 4.3, can connect to that wireless network without any problems, so can my Kubuntu 13.10 laptop with an Intel wireless card.
Tried so far
While looking for the cause and a fix for the problem, I found numerous posts that suggest to use a static IP address. This is a legitamate workaround, and I might resort to that, but I would like to fix this in general.

The first thing I tried was to change permissions of /system/etc/dhcpcd/dhcpcd-run-hooks to 555. This did not have any effect, though.

Then I downloaded the WiFix app and ran it in automatic mode. Did not do anything either.

Last thing I tried was deleting /data/misc/dhcp/*. No effect at all.

Update 2014-02-21: As you can see in the screenshot, the signal strength is really weak, although the phone is one meter apart from the router with a desk in between. Now it connected while being on the table. The signal strength is full now. I read in a different question that the issue might be caused by a weak signal. Could that the be underlying issue?
My router does not have an external antenna, therefore, it might be a little unpredictable where the signal is strongest. I set the phone onto the router, and it still had the problem. So signal strength should not be the issue.

Update 2014-03-04: I installed the latest nightly build of Cyanogen Mod on the device using their instructions. This installed Android 4.1.3, which had a severe problem with the wireless. It was turned off when I started the device, and it got stuck at activating wifi. So I reverted to the latest stable version which still has this endless loop.

Update 2014-03-04: For my home network, I set up a static IP address, although I really do not like it. However, the internet connection works now.

Update 2014-03-06: Checked for /system/bin/sh -> mksh, and it is present. This does not seem to cause the issue.

How could I fix this apparent DHCP issue?

I had the same symptoms while cooking a ROM when the symlink of /system/bin/sh to mksh was missing.

Try changing the WiFi channel in your router settings. This fixed the issue for me.


Error: An application has been forced to stop for an unauthorized attempt to access system in your device. I am getting the following error message every now and then. As far as I notice, it only happens if my phone has internet connection mostly on Wifi.

an application has been forced to stop for an unauthorized attempt to access system in your device. it may be    safe to delete an application obtained from an unauthorized route. Check now?

When i click Check Now it just shows me list of all apps but don't tell me which is having problem. It is Samsung Galaxy Note 3 and it is not rooted or i don't remember i installed any application which is not from Play store.

I googled and researched and found other people is getting same problem but i don't see any way to solve it. Anyone here knows how to fix it?

When it appears, long press on the message and it shows the app causing the problem. (It probably is Knox.) Clear data and clear cache, that worked for me.

My friend has a note 3 with the same problem. We found a solution here:

How to reboot a frozen Android device? When an Android device locks up, and does not respond to holding down the power button, is there anything you can do to reboot the device besides removing the battery?

What do you do if the battery is not removable?

Although it does not always work, Windows has the three finger salute (Ctrl+Alt+Delete) which helps get around this situation.  Is there anything similar in Android?

I did find this question, but it does not refer to a device that is frozen.

Different Android devices may have different force-reboot methods, so you should refer to your device’s documentation. To reboot frozen device you should usually press and hold the Power button + Volume Down button (or Volume Up button - it depends on device) for at least 7~10 seconds and stop holding those buttons once it’s started the reboot process. You could try to press and hold just the Power button itself for at least 30~45 seconds.

Try holding Power + Volume up button.. might help


I have multiple google accounts. How can I hide some of them from the Gmail and Calendar apps? I have several google accounts I use for different purposes (i.e. my main everything account, one to log in to less secure websites / games, one shared account for work, my wife's Play store account).

I only use my main account for the gmail app and two accounts for the calendar app. I have customized the synchronization options under settings -> General --> accounts but even though I disable synchronization of Gmail, the accounts still show up in the calendar and gmail apps. How can I make these go away?

I use a rooted Note 3 on t-mobile.

Thanks!

On Android 6 and lower you can install Xposed Framework and then XPrivacy module for Xposed. In Xprivacy, deny access to accounts for the gmail app. Then add the account you want visible to the white list.

You can have a separate white list for every app, so you can have different accounts show for different apps.

Some apps get their account list from Google Play Services, and I've had weird things happen when trying to block accounts from that. But gmail and calendar work fine. Hangouts has a sign out feature, so you don't really need to block, but blocking works there, too.

Honestly how you might so that, is a many varied answer. Bur it can be done. For instance. Android itself pretty much requires you to have a google account, its used as your primary backup. This account ibwouks suggest veing your most secured account. Being fortified with 2fa / ontpw and even havinf email or app prompts aby time the device is signed into or loged onto from a new source.

Then instead of signing your ither accounts into the device itself, you have the browsers. Firefox chrone chromium opera can all handle multiple accounts signed into then without actually being signed into the phone/pad itself. Almost all of the browsers have a way to lock thier access from from prying eyes. Chrome/chromium actually require you at least be signed into the app, just use another account youre not as concerned with hiding but havr if fortified also wth as man security mechanisms as gou can set. Firefox and opera also employ a sign in account for signing in and syncing.


What do I say to make a new line when using voice recognition? I've found I can make punctuation happen by saying "comma", or "period", but I can't find the word for new line.  I tried "paragraph", and "line break", but it just prints those words.

I found that saying period newline gives you a new line, after putting a period on the current line.
Also period new paragraph work.

without any punctuation at the end of what I say I can just pause and say

"New line" and my droid x goes to next line


WiFi never shuts off on Nexus 5 running Lollipop I have Nexus 5 on Android Lollipop. When I check the battery graph, it always shows my WiFi radio as ON, even when I am using 3G and have specifically turned it off. I have observed that it only shuts off in airplane mode.

Screenshot (Click to enlarge image)

How to correct this behavior?

I have a nexus 5 and had the same problem. I found an app called Power Toggles and it seemed to do the trick.


What does "discover known accounts" permission mean? I am not sure what an app can do to me if it is able to discover my account, to what extent?

Thank you very much.

This permission is of moderate-high importance. This allows the
  application to read what accounts you have and the usernames
  associated with them. It allows the app to interact with permission
  related to that account. An example would be an app that was restoring
  your contact, would discover your Google account then send you to
  Google's login screen. It doesn't actually get to see your password,
  but it gets to work with the account. This is also legitimately used
  by applications to add contacts to your accounts, such as dialer
  replacements and contact managers/backup/sync/etc.

Source

Its a huge security hole because it allows an application to add your facebook and google and other account names to your online profile without you realizing it. If the site is hacked the hackers could follow through to other know accounts if you were stupid enough to use the same password. Lots of people are that stupid so it will happen.

An online dating site or porn site might leak your real facebook and google account names to the people you are chatting with even though you never gave that information to the site itself.

Anonymous online? Not any more.


Galaxy Nexus; no signal after flash roms I have a 'Maguro' Galaxy nexus, purchased from O2 in the UK.  I am now in the US on T-Mobile.

My phone was working fine until yesterday I flashed the most recent CyanogenMod nightly, now I get no signal. Under Network Operators I get a list of AT&T and T-Mobile but clicking either gets an instant fail.

I've now tried flash all kinds of Baseband to it, XXLJ1, UGLL1, TDVMK1 to name a few.
I've tried installing the google 4.3, 4.2.2 and 4.1.2 images, all of which come with XXLJ1 - still no luck.

My previous ROM was a stock (but rooted) 4.1.2 (I think) , but I have no idea on the radio.

Any suggestions what I should try next?

Update:
I've just checked my IMEI number and the one the phone reports no longer matches the one on the sticker :\

I had the same problem, and the solution was to re-flash the stock ROM.


Lockscreen rolling notifications like iPhone I like everything about my new Samsung Note 3. It is a superior device in almost every respect to my previous phone the iPhone 5.

But, I have one issue that I have not yet resolved. I cannot get the level of detail notifications that are automatically shown in a rolling notification queue like the iPhone (see images below, iPhone on left, Android on right).

The notifications are shown in the queue in the order they are received regardless of source (sms, email, calendar notification, etc).  They are scrollable vertically, and a swipe takes you to that specific message, event, email, etc.

This is one area the iPhone did very well, and I relied on the timeliness and dependability of that feature.

I have downloaded several lockscreen and notifications apps, but none are close to what I described.

Any suggestion?

I really appreciate any insight.
Thanks

Ok.  I didn't get any specific responses/solutions (thanks for the comments I did get thought), but it did prompt me to dig deeper since no one had an answer.

I looked in the Google Play store and found several apps under "Lockscreen", "Notificaitons", or a combination of the two words.  I found several apps that had some good features, but none really came close to providing rich/detailed notifications.  Some apps that I installed and tested.

-NiLS Notificaitons

-WidgetLocker

-Lock Screen Notifications

-Espier Notifications-  this one was promising, but never worked quite right

In the end, I found one APP that doesnt show up with the keywords "Lockscreen" or "Notificaitons".
This APP required a lot of configuration, and you have to install some helper email apps.  But the final result is acceptable(image below).  It also has some nice features, like the ability to add widgets (in this case I added a weather widget).  I could never do that on iPhone, so it may be a good trade off.

Executive Assistant Paid Version
AND
Executive Assistant Free Version

I hope this helps anyone looking for rich "iPhone" like notifications.

You can try Echo Lockscreen which does this.


How to disable Play store from updating itself? I don't quite like the new design of the play store, and wish to stay with version 3 of it.

Is it possible (by root if needed, and I think it is needed) to disable it from auto-updating?

Will I even miss anything from the new versions ?

For now, the only solution I've come up with is to use the really old 2.3.6 version of the market app.

This is the only one that doesn't auto-update itself.

In order to install it, you have to uninstall the play store, install it, and convert it to a system app.

If you wish, you can use titanium backup to backup the old version for later use.

Here is how you do it:

Open Play Store
Tap the top left corner to open the menu
Select "Settings"
Under "General" there is an "Auto-Update" with 3 options


Pokémon Go without Google at all I bought an android phone recently and tried to use it without any Google account and so far that was alright.
But I wanted to try Pokémon Go today and I cannot play without signing up with a Google account.
I heard that you could create a Pokémon club account instead of Google but I don't even have the option, only the button to sign up with google appears.

Does anybody have a solution for that?

Unfortunately Creating a Google Account is currently your only option, It's not hard to create a new account and it will probably be beneficial for many other applications you might download.  It's annoying to create a whole new account just to keep things separated but it's necessary to gain access to Google's location features on Android.

Its only in certain countrys as part of a limit release for the beta but thankfully apkmirror uploaded it , they're a very safe site enjoy.

How to prevent specific apps from using mobile data? So there are some mobile apps that love to use lots of mobile data, and sometimes use it when the wifi signal isn't good (e.g. Spotify). Which then leads to a nasty surprising spike in data usage during those times.

My phone is rooted, btw.

Android itself does not provide such a tool,
but you can use firewalls that require root,

If your device is not rooted, so no problem, there are some applications that use some trick that can prevent apps from being connected to internet, such as NoRoot Firewall.

  The Trick of NoRoot Firewall is that it opens a Fake VPN connection
  for making the phone to send all the packets to the Application then you
  can define for the application which one to allow and which one to
  deny.
  So it does not require root access.

If your device is rooted you can use Droid Wall  and it will do what you want.

you can download it from Google Play Store.

Note:I'm using NoRoot Firewall on My Xperia S and Xperia Z1 for a long time, even my Xperia S is rooted but i still use this application for blocking apps from being accessed to Internet.

There is a tool in your mobile data setting that is turned on by default that makes this happen. Go into data settings and uncheck the box.


Will a firmware update erase my personal data? A friend of mine has a Samsung Galaxy S5.
It is actually prompting to update the firmware. But the updatetext (its actually in german) reads ambiguous. Translated it says something along the lines

Initalize the latest Version.
All configurations will be initialized and saved data will be erased.

The problem with the german text is it isn't distingtive this means just the Configurations data or ALL data. I wasn't able to find someone having this problem by googling (I'll just get spammed how to delete/erase the updateprompting...)
SO I'm asking here:
What kind of data is meant to be erased for a Samsung Galaxy S5 when performing the latest firmware update? (If it matters, current version: PDA:OJ1 / CSC:OJ1 / PHONE:OJ3(XEF))

Do a backup of your phone's important files, don't risk it, if the phone reinitialises it isually resets it to its factory version, erasing all the data. Also your apps are very likely saved in a list so that you can reinstall them after the reset, so don't worry about them. Use google drlive or some other service, take the SD card out, and do the firmware update, if you want. Just don't risk it.


Force links to open in the app, not the default browser For example, I get an email from Pinterest with interesting links for the week. When I click a pin, it opens in Chrome and not in the Pinterest app. This happens with a few apps and was wondering if there's a way to "open link with" type of feature.

Is it possible to force the links to open in their respective application and not in the default browser (e.g. Chrome)?

Apps can request that links be opened using the app, using an API called an "intent filter".

If the app has the correct intent filter, you will be prompted to open the link using that app, and the app will then do something with it.

This has to be coded in by the app developer, and there is no way to implement it yourself unless you decompile the app and add it in.

An example of an app that does this is the Google+ app.

The developers of the apps are the ones who add a browser into the app via an update. If the app developer of the Pinterest app has not added a browser functionality, then there's no way to make external links open in the app.

When developers add a browser to the app, then you can choose whether you want to use the default app on your device or the in-built app browser.


Nexus 5X bootloop, recovery mode doesn't exist Yesterday my Nexus 5x froze and  started bootlooping, it did start twice since yesterday but only for a couple of minutes. I tried going into the recovery mode, but as soon as I click the power button to enter the recovery mode, it goes back to bootloop. Also tried going into safe mode once, but that didn't help.

I have already tried flashing the device with the Nexus root toolkit, but the problem still exists.

TechTimes reports that:

  LG is currently unable to repair Nexus 5X smartphones affected by a so-called "bootloop" malfunction, so it's issuing full refunds to make up for it.

so I don't think there's anything you can do to fix it.

Try to use adb from pc, with the prompt commands


Make all new chrome Windows incognito Is there a way to make all new Google chrome Windows on my Android be in incognito mode? Thank you!

For android you need to have your phone rooted. Then you can go ahead and install IncognitoTab in xposed modules and it will work. If you want private browsing without root then download another browser like dolphin or Firefox.


Music only plays for a second and then ends? When I successfully copy my music to my SD card, each song only plays for a second and then continues onto the next song. I was able to remedy this by copying each song over individually, but obviously this is untenable in the long-run. Might this be an issue with my new SD, am I copying too fast, or what else might it be?

I was able to replicate this for skipping to the center of a song. I can't hear an entire second, but it does seek to the center of the song and play a bit of it. If I try to go back to the beginning of the song after every skip, the Music Player eventually crashes.

For any of the mp3s with these issues, if I restart my phone it deletes these songs.

The most obvious explanation is that the file is incomplete: there's only a small fraction of the file there, or only the first section of the file is readable. Given that the symptoms you report in your other question point to SD card failure, that seems the most likely cause for this too.

If this is a different SD card, it could be that the card itself isn't at fault: rather, whatever you're using to copy files to the card could be corrupting the filesystem, or a dodgy USB connection to a card reader could be interrupting file transfers.

When you transfer music files do not transfer multiple files at the same time.


Allowing app installs from “unknown sources” for Secondary Users on Android 4.4.2 I see that "Unknown Sources" under Settings → Security on Android 4.4.2 is greyed out (I can't enable it) for my Secondary user on my Nexus 7, Is it expected behavior? Is there any way to enable it?

Android by default does not allow secondary users (Restricted Profiles) to install apps from Unknown Sources.

But, under Application and Content restriction for the particular user, you can enable specific menu in Settings menu. You can check whether Unknown Sources can be enabled.

Enable it from the Owner user then it is enabled for all secondary users


Problem to uninstall AirDroid: Unfortunately, Settings has stopped When I try to uninstall the app I got this message:

Can't uninstall because this package is an active device administrator.
In the same window I have a button: MANAGE DEVICE ADMINISTRATORS

When I follow this button I'm in Device administration settings. (normally you can reach it when you follow: settings -> Lock screen and security -> Other security settings -> Device administration settings) There are three items each of them have a switch on the side, which is turned on. When I try to unswich AirDroid, I got after some seconds the error message: Unfortunately, Settings has stopped. Also I'm not able to uncheck the other both items, but there is a different behavior.

I try to solve this error by cleaning the cash with no effect.

I like to remove the app because finally I don't need it and it consume a lot of battery even when I don't use it.

I have a Samsung XCover 3
with Android 6.0.1
and Kernel 3.10.9

The disabling Find Phone this has solved the problem! You must disable it within the AirDroid app.


Want to change country in Google Play store This is not duplicate of other questions. I've been struggling with this issue for last 3 weeks and have contacted Google over chat, forums and other avenues too without any luck.

I moved from USA to India and now some of the apps can't be downloaded due to payments profile being in USA with an active Google Domains subscription.

So far I've tried following steps -

Went to payments.google.com and created another profile with India as country. Now I can see two payment profiles as USA and India.
Added credit cards etc so that it's a valid one
Went to Apps > Play Store and cleared cache and data. Removed my google account and restarted my phone to add Google account again.
Can't delete my cc info from USA payments profile due to active Google Domains subscription. Tried cancelling it, but it takes me to Domains billing page which again asks me to go back to payments page to cancel. So kind of catch 22 situation here.
Unless I cancel Google Domains subscription, can't close my USA payments profile.
Went to Google play to purchase something and it doesn't allow me to buy anything with India card, so other solution to at least reach 'Accept & Buy' stage can't be done.

I'm stuck with USA google play store now and would appreciate any help to change country so as to get to useful apps.

One option to do that is going into your Google Wallet Setting and add a new profile for that Country / Region

Add a new gmail account to your phone.  In Google Play app, select the new gmail account using the drop down arrow, then set everything up using your new country address and cards :)


What are the differences between the two Samsung Galaxy Tab 4 7.0" models? I have just got a new Samsung GALAXY Tab 4 7.0" (SM-T230NU).

What is the difference (or improvements) between the 'stock' SM-T230 model GALAXY Tab 4 7.0" and the 'newer' SM-T230NU, recently released for US/Canada and in EU?

Are there also other NU devices? I have also seen references to the GALAXY Tab 4 10.1" as SM-T530NU.

I have found one possible issue, with the SM-T230 not having multi-user mode:

  The multi users setting is not available. According to the manual it should be at settings => General => Users.

(My device does have multi-user capability)

I also saw a reference to the two different models on XDA Developers:

  Do make sure your tablet is a T230NU model and not just a T230
  model.

UPDATE: 04-Jul-2014

There are three variants: T230, T230NT, T230NU

from: Samsung T230 | T230NT | T230NU Galaxy Tab 4 7.0 WiFi Firmwares

According to other reviews, the plain SM-T230 does not support OTG,
but the SM-T237p does.

I remember how disappointed I was to find this with my SM-T210R.

SM-T230nu has an IR remote, while a simple tab 4 (SM-T230) doesn't have one.


My phone's 3g/4g randomly stopped working I have a Galaxy S3 and my 3g/4g suddenly stopped working. WiFi works fine, but how can I get my 3g to work again? I have already uninstalled apps and deleted unnecessary photos and videos.

Check that flight mode is not swithed on. This mode will disable any network (Wi-Fi, cellular network, etc).

Else, go to Menu | Settings | More Settings | Mobile Networks | Network Operators (Note: your menu options might be different due to the Android version installed on your S3) and reconnect to your telecommunication provider's cellular network. Note: You may need to select your telco provider's name when your S3 displayed a list of cellular providers.

Also, shutdown your S3. Then, take the battery out for 30 minutes. Reinsert the battery. Boot up your S3 and turn on Mobile Network option and see if 3G/4G has been restored.

Worst case, it could be an Android firmware's update that is causing the S3 to fail to connect to any cellular network.

Samsung phones usually take a while to switch on data. Wait for few seconds. Also try a reboot, that resolves the issue most times.


How Do I Get Rid of Apps from Play Store Update List? For the past few months, I have had the following items in my Play Store update list:

I do not have these apps installed on my device. I do not want these apps installed on my device. Yet I do not see a way to get rid of them from this update list.

How can I get rid of these apps from my update list?

Try going to "Settings > Apps > Google Play" and then pressing the "Clear Data" button. Then go back into Google Play Store. You may have to sign in again but I doubt it.

You can stop app auto update in setting follow the instructions below, or you can get your app file from another website like downloadfreeapk.com so that your apps will not get auto updated.

Thank your for your help :)

Do you have adb installed? Added the android rules and etc? I was in the same boat last night kind of, was trying to run a logcat. Google adb for whateverdistro you are using. Once I set up adb/android rules, my phone would show up via lsusb

Also, not sure if it matters, but do you have USB debugging turned on?

I assume since you are trying to build an image, that you know the basics, but have you tried searching/posting on xda as well?


Can I use my phone as a bluetooth game controller for my computer? I've seen BT Controller but I think it only allows users to use their android as remote for other androids. I just want to use my phone as a bluetooth controller with up, down, left, right, L, R, start, select, A, B buttons for my computer. Is there an app that makes this a possibility?

Basically, there are generic bluetooth game controllers that can be bought on stores. I was wondering if I can make my Android phone act like such and be used on computers.

You haven't mentioned which types of games you need this for but there are several possible options:

Gmote 2.0, which is a client/server type system which would let you use your Android tablet to control your computer.

RemoteDroid, which is similar to Gmote, it also uses a client/server system.

GRemotePro may be the right choice for you as it is but you need to pay for the server software. It is specifically advertised as being for game control.


Why I am unable to check balance on BSNL Mobile in Android Phone? I have just ported my Tata Docomo number into BSNL Mobile and it is working good. But I am not able to check my balance and recharge top up coupons because USSD code that we run, like *123#, are not working. It says "Connection problem or invalid MMI code".

Unfortunately, it is happening only in my Samsung Galaxy Y Duos GT-S6102 which is based Android 2.3.6 Gingerbread. I tried on another cell phone and there was no error. Talktime balance showed up and even I recharged with the top up coupon.

My phone has dual SIM support and there is no corruption on both SIM ports. Message centre number for BSNL mobile is also correct and I am able to send SMS too. There was no problem with Tata Docomo either.

Don't know what's the problem with MMI codes.

Exchange the SIM cards with two different handsets and replace it as earlier. This worked for me.
