my mail won't show after upgrading to 4.0.4 After upgrading my Samsung galaxy s2 to android version 4.0.4 my mail won't show in the default mail app (cant find out the name!). I only get a dropdown bar -- but when I clicked it, the arrow points below, but it doesn't "dropdown" ;(

How can I get my mail shown?

Here is a screen-shot of my mail app.

When chaging Android major versions, GB to ICS or ICS to JB or even GB to JB, its advised to do a full wipe, since many old files from the previous version might collide with the new Android version.

Since you haven't done it, I suggest you do the following:

Backup all your phone's data with either Titanium Backup or a Nandroid backup if you have a custom recovery installed.
Get your phone to recovery mode and wipe all data (factory reset). If you have a custom recovery you can wipe /system, /data and /cache.
Once clean, reboot in download mode and use Odin to update to 4.0.4 (or 4.1.2 if you have the international version GT-I9100)
Reboot and enjoy a clean installation of ICS/JB.


Android System problem - Unable to share files, do factory reset I am using a Micromax P362 tablet with Android 4.1 Jelly bean (rooted). This problem occurred a month ago. The app named "Android System" appeared in the 'Downloaded' section of apps. Yet it is not seen in any other app managers (such as Link2SD). When I press in uninstall updates, the app just disappears and all apps hang periodically until I restart tablet. Now the problem is that 'Share via' option is not working and even factory reset option is not working. So, how to make Android system app function normally?

Any help is appreciated

Edit: Another problem is that app permissions are not normally displayed. Eg: Instead of "Internet access", it displays "android.permission.ACCESS_INTERNET"

Apps that can't be uninstalled are apps that come hardwired in the ROM of your Android device. These are typically vendor specific apps or the Google apps.

"Android System" is pretty crucial to your device, so it's weird it's even possible to uninstall it's updates. Every Android device as this, but normally it's not listed. You can see it pop up in your battery usage statistics however, which is totally normal.

To fix your problem you probably need those updates to be installed again, but I doubt that will be possible using the Google Play Store app update system.
You can check, but I doubt it'll be there.

Another possibility is by checking for system updates for your device.
How you can do that depends on the tablet/os version etc, so I can't help there.
On my phone it's in the settings under "About my phone", which has an update check option.

A factory reset fixed my problem (using adb)

adb shell
wipe data

Thanks for all the help.


Remote factory reset and changing Google password In case I ever lose my Nexus 4 phone, I've opened to the Google Settings app, then tapped "Android Device Manager" and from there, I've enabled both "Remotely locate this device" and "Allow remote factory reset."

Then I can use Android Device Manager online from anywhere to ring or reset the phone.

My question is: in the event my phone is stolen/lost, I'd probably change my Google password so the phone can't sync any more while I attempt to find it. If I change my Google password and then reset my phone after that, will the remote wipe still work since the Google password changed?

Note: I have 2-factor auth enabled, but keep in mind my phone and the apps in it are already authenticated.

Why not for sake of it, activate 2-step authentication on your Google account?
And just use the random generated password instead, be sure you have enabled Google to SMS you for any login attempts on your Google account, and keep your real password hidden. That is what I use here, where-ever I log in, I get an SMS direct to me, asking to enter the verification code, no one else has it.
Also, it would be easier to just revoke it from your Google Account settings page, i.e. access denied.
I use a spare, crappy phone that I carry with me everywhere, zero chance of anyone trying to steal it, that receives the Google SMS notification, and yes, its a dumbphone :)
Edit
To clarify: Your account on the device is called a Application specific password. See the Revoke beside each application specific password.
In event of phone or should I say, device getting lost/stolen, its a matter of simply clicking on it. That is what I was referring to, in my case, I have the application called "My smartphone google account signin", and if it gets lost, I click Revoke, even after factory reset, data is wiped cleanly for my peace of mind.
I still have my laptop as my authorized login, that is, I can use my real password on the laptop, everywhere else Google is accessed, is using the random generated password. And if I was to login on another computer using my real password, the verification code gets sent to my dumbphone which I check and use.

Some phones may be bypassed with no problem - you just need to launch settings from a USB-OTG cable/drive, do the factory reset in the Backup settings and clean up all data related to Google accounts. After that you should do the reset again and FRP will be reset. So you will have an opportunity to use your phone like a new one.

What does the "Force stop" button mean? When I go to Settings > Applications > Manage Applications > Downloaded I see an application list. If I select some applications I see button "Force stop" active, but some applications have this button dimmed.

What does it mean? What happens if I press this button?

This button can't mean application running, since the applications with this button are not listed in Running section.

Can I list just applications which have the Force stop button active and uninstall them?

Android version: 3.2

As said in my comment to paco's answer, the information he gave is mostly correct: Most apps don't exit completely if you leave them, and no app should exit if you leave it via the "Home" button. Moreover, some apps have background services running which the user otherwise cannot quit.

Now there are some situations where you need an app (including its background services) to be stopped -- e.g. if you want to uninstall that app (or, in case of a system app, its updates). You will notice this when the "Force Stop" button is active, the "Uninstall" (or "Remove") button is grayed out -- but the latter gets activated when you stopped the app via "Force Stop". (If both buttons are grayed out, you can tell it's a system app, by the way -- which you cannot uninstall).

Btw: If the "Force Stop" button is grayed out ("dimmed" as you put it) it means that app is not currently running, nor has it any service running (at that moment).

This button is active for apps that are running or are be running since the last time that you started your device.

Android do not kill the apps totally when you exit from it, this button is for close completely the app and remove it from the stack (apps running), also this button free the memory used by the app.

There is no way to list the apps running, also the apps running in background have this button.

There are free killer apps in the Play Store, to manage the memory of your device automatically.


How many clients can be connected to a WiFi Hotspot? I want to create an application which hosts a sever in my phone and many people can use it after connecting to my wifi hotspot.

Suppose I want to implement it in a classroom with 50+ students, is it feasible?

I want to know how many clients can be connected to the wifi hotspot. Are there any limitations?

Note: Partial answer regarding no. of hotspot connections that can be connected to a device.

Google on the page "Set up tethering or portable Wi-Fi hotspot" has stated:

If your device has mobile data, you can turn it into a portable Wi-Fi hotspot for up to 10 other devices, like laptop computers[.]

See also,

These features depend on your mobile device and your carrier. You may be charged extra for tethering or Wi-Fi hotspot connections. If you have issues, check with your carrier to see whether tethering can be enabled.

As Andrew already mentioned in the comment, the results on web usually tells the limit to 5,6,8,10, but not more than 10.

I could not find any content that states that hotspot could connect more than 10 devices. One person mentioned(I asked) a limitation vaguely here(in the comments).
IMO, you can't connect more than 10 devices, not without a hack. And to hack, you need to know why you can't connect more than 10 devices?

Please, do ping here if you(reader) come to know the reason.

There can only be a 5 clients at a time on a Wi-Fi hotspot.


How to prevent Wi-Fi from disconnecting during a WhatsApp call? On the latest version of WhatsApp (2.16.133), the Wi-Fi keeps disconnecting during a voice call.

I suspect it's due to the screen going off (here's a similar problem on the iPhone), but it's just a wild guess.

Anyone knows a fix for this? I'm on Android 6.0.1.

If you have Avast battery saver, uninstall it. It keeps disconnecting your wifi.


Samsung Galaxy S3 not connecting via USB Since about a week, my S3 doesn't connect anymore via usb to any computer.
I don't think it's driver related as it was working before and I didn't change anything on the computers.
It now runs Jelly Bean but it didn't happen right after the update (only after a week or so it stopped working).

The S3 doesn't even show the notification with the usb icon nor the possibility to switch between PTP & MTP...

I tested with 3 different usb cables, on vista, win 7 and mac os x.
Tried to activate / deactivate usb debugging, restart the phone and event done a hard reset, it's still not working.
Phone is not rooted

Maybe it's hardware, but the phone didn't fell or anything like that...

Do you have an idea ?

I just had the same problem tonight.  All of a sudden my pc wouldn't recognize my S3 when I connected via the USB.  I tried the USB debugging first and restarting...didn't work.  I popped the battery out and restarted, and the USB icon showed up. Hope that helps.

Thanks for all the helpful troubleshooting ;)

If you haven't figured it out by now.  The easiest way to fix this is to power your phone down, remove the battery, wait about 30-60 seconds, then put the battery back into the phone.  I have had a similar issue and this has fixed it just about every time.


Unable to upload attachments in the yahoo mail I am currently using the Xiaomi Redmi 1S device with Android 4.3 operating system.I log-in through yahoo in my mi browser and try to attach an image.The problem comes in attaching an image under the attachments option.

Steps Followed to attach an image:-

1)Clicked on Attachment icon under the mail.

2)The browse page loads and i click on browse and select the image which i want to send.

3)After selecting the image it instead opens another blank page.

4)Tried going back and re-select the image but again upon selecting the image it opens a new blank page.

I cannot pin point where exactly the problem is(whether the WiFi or the browser).

Note:-The image gets selected under the browse option very rarely(i.e in 4 times i try the image gets selected only once and it get's difficult if i try to attach multiple images )

My original answer got a downvote, despite being a valid suggestion. :P

So, I'm going to try a different answer.

You are using a Xiaomi device, and you probably won't find a lot of Mi users here. They (MIUI) have their own forum, and you will probably find better support there.

The Mi browser you talk of is not available in Google Play. So, I'm willing to bet it's a custom browser packaged with the MIUI ROM, and I'm willing to bet it's not a very good one, given the problem you just described.

So, I'd suggest that you install a 3rd-party browser like Dolphin Browser. In the screenshot below, you can see that the image was attached even if Yahoo Mail was either in desktop mode (left) or in mobile mode (right).

Otherwise, just save yourself the trouble and just install the Yahoo Mail app.

If the website is giving you problems, why not use the Yahoo Mail app instead?


Root permission doesnt appears for me to accept I rooted my Android (HTC Desire 2.2) permanently with z4root, and it was rooted successfully. Root checker confirmed that it has been rooted. I downloaded DATA2SD, when I opened it, superuser was installed and asked me to confirm/accept root permission for DATA2SD. It was working properly.

After a few days my phone was updated from 2.2 to 2.2.2 according to my system scheduled check for update online. After updating, I realized that DATA2SD wasn't working: it says "DATA2SD cannot work without root permission"; it never asked me to accept root permission anymore.

I then checked again with root checker and it said "No root" but when I try to root it says "Your phone is already rooted, do you want to root again?" root checker says its not rooted. SuperUser is still installed, but I don't see any root permission to accept.

Any help? What should I do? I want to unroot but can't unroot.

use framaroot to unroot it you can install the apk and run,it will show option to root it or unroot it and you can check the unroot your phone will be back to normal as you got it from factory

Download SuperSU from play store and try again. Or re root your device using original method.


Can I restore downloaded paid apps after a factory reset? I need to factory reset my phone.
However, I need to know whether I will be able to download
the applications I paid for on Google Play once I do the
reset, and download them onto my phone at no additional cost.

If once I do a factory reset I need to pay again to download
all the apps, then is there a way to back them up prior to
doing a reset, and then reinstall them back again?

Once bought, always yours. New device, factory-reset, does not matter -- as long as your account stays the same. Paid apps are bound to the Google-Account you've purchased them with.

To give some proof: I use several apps I bought once on 3 devices simultaneously. I never was asked to pay again when installing them on the next device. Provided I used the same account, of course.

Download Easy app backup & restore.  It will create a backup folder in your memory card from where you can get all apps. Whenever you need the app you can install it from there.


How to open Microsoft Excel files? I would like to read my Microsoft Excel files on my Android device. Is there anything built-in natively? Is there an application for viewing and editing Excel files on Android?

You can try Documents To Go. You can create, edit, and view MS Word, Excel, PowerPoint, and even PDF docs.

As a free alternative, you can upload your Excel docs to Google Docs and use the free GDocs app.

For only reading .xls files you can try ExceLens from Google Play


I have over 2GB of internal memory and can't install or update some apps I tried to search for some answer but couldn't find anything.

I'm using cyanogenmod-11 on a Samsung Galaxy S4 Mini.

I am pretty sure I have enough space on the internal memory, but I still receive the insufficient space message when trying to update and/or install some apps, but not all of them.

What could be the problem?

Try the fix permissions entry in your custom recovery menu. In most cases this fixes the problem.

Will installing Cyanogenmod speed up my Galaxy S? I recently purchased a used Samsung Galaxy S Captivate. While it seems fine for my purposes, it would be nice if it were just a bit faster, in terms of loading different pages more quickly. From what I've seen, Cyanogenmod claims that it's faster than many stock roms, since it doesn't use the company's extra interface, which, in this case, would be TouchWiz. However, Cyanogenmod would also bring my operating system up to Android 4.4, and I'm not sure how much additional power that would take. I'm also open to using older versions of Cyanogenmod, if that's feasible.

Would it be better in terms of performance to keep my phone at the stock rom or to install Cyanogenmod?

In theory, your phone should perform considerably faster with CyanogenMod 11, because KitKat was designed with entry/mid-level phones in mind; requiring only 512 MB of RAM to run. (See this page about Project Svelte for more information.)

CyanogenMod also adds a whole slew of features like Heads Up Notifications and Privacy Guard on top of the AOSP code, so your phone will not only be fast but also be very useful.

Keep in mind, however, that CyanogenMod (along with others such as PA and OmniROM) are third-party ROMs, and therefore lack the various "enhancements" that the manufacturer has made in the stock ROM; so don't be surprised if you see that the camera doesn't perform as well, the battery drains faster than usual, etc.

Never do that. Perhaps it helps to increase your speed but it consumes much more power.
If performance in CPU increases, undoubtedly,the power usage will increase dramatically. Try to keep your factory ROM and looking for some good free app in the market for increasing the speed.


What is this Google Settings app that installed itself on my phone? Today, all of a sudden I saw this app in my Samsung Galaxy Y mobile phone:

I am talking about the app named "Google Settings"

I uninstalled it immediately only to find it installed again a few hours later.

My mobile phone is rooted and I did have access to internet through the phone during this period?

Can anyone tell me as to what is going on? Should I worry? What should I do?

The Google settings app is being put their either by the Maps app, Search app, or the Google+ app.

It's a unified settings/sign-in thing they just added in literally yesterday and allows you to manage the settings for all of the above (and probably more in future) from one menu.

http://www.engadget.com/2013/02/27/google-settings-app-sneaks-onto-android-to-bolster-g-sign-in/

I unistalled google play services and that removed it from the phone. Not sure what else will be affected but I am still able to download/install apps from play store. I figure I may miss the next version of play store that comes out. Better than them sneaking stuff in

But Home button stuck randomly while using and sometimes Volume button also has same problem. read brief in http://eviltek.blogspot.com/2013/12/how-to-fix-samsung-galaxy-note-3-loose.html

How to Fix it

If your device is still in warranty I'd stop fiddling with it and get it fixed at an authorized service center. Opening the device yourself will void warranty.

It is a broken phone. send it back to Samsung. I also use the features that it comes with and mine works fine.


Difference between Gapps What is the difference, if any, between different Gapps providers such as opengapps, tk gapps, pa gapps etc?

Open gapps is open source developed, all their code is available on github. PAGapps is developed by the Paranoid Android team. So there you have it. An app doesnt have to be created by google to work as a google app. Other developers also give you a choice as  to whether you want all or just one google app (gapp) The pico is just the play store, if I remember rightly. I no longer use any Gapps at all. I use a separate apk downloader called Raccoon with a throwaway google account.

How to prevent Google from asking for location permission when enabling GPS? I took this new phone which had a notification about an update. Thinking it is like Windows OS where I must have the newest updates for proper security practices- I agreed for the update.

Turns out it has become a Lollipop device now. It wouldn't be much of a problem except that the owner who has no Google account and want to stay away from them as much as possible, sharing as little info as possible- now gets a popup every time she turns on the GPS, asking her to share her location with Google ("use Google location services").  She keeps hitting 'Decline', but other than being annoying, the demand is obviously destined to be accidentally accepted one day.

I've spent the entire day looking for a solution and I'm fairly desperate. I am not allowed to install any 3rd party GPS app on the phone nor can I revert to the previous version if it involves me downloading some file from the internet (not from an official source) and trying to flash the device (I'm inexperienced and afraid to brick the device as well).

Can anyone help?

P.S.:

Funnily enough the popup has a "decline" button, an "accept" button, and a "don't ask me again" tick box- however when you choose the tick box- the "Decline"  button disappears (turns grey).
I just want to add that it goes without saying about a root being out of the question.

How do you get ride of the pop up ?

Hi ,there is a simple solution go to settings > location > Mode and
choose device only , the phone will use only the GPS sensor to get
your location it is more than enough because any app that want to get
your location will get your Coordinates (X,Y,and altitude too -height
above sea level- )

What is causing the annoying pop up ?

The pop up shows up becuase you choose high accuracy when you choose
that option the phone will use ,your cell network ,wifi hot-spot and
GPS sensor to determine your exact location in order to do so the
phone need to send hotspot location or network antenna location.


How to edit Sony Xperia J dictionary I like to use the built-in dictionary that suggests words when I use SMS or Hangouts.
It works okay but I'd like to edit some of the words it suggests.

Where can I edit the built-in dictionary? Is there a function for it?

Xperia: you can hold on the word displayed  and u have an option to delete it.
You can add words by going through 'language & input' then add your words in 'personal dictionary'.

I would like to edit from a 'list' of saved words but I haven't found my way to the list.

open this PDF file and go start reading from page 23 (right column) about how to access the user dictionary. The instructions of editing user dictionary are on page 25 (right column). hope this helps.

What happens after Unbricking a Oneplus 3 There are many guide to unbrick the oneplus 3 and I followed the  [GUIDE] Mega Unbrick Guide for A Hard Bricked OnePlus 3 on xda by Naman Bhalla and after the step 9 this is my condition now
 i cannot access the recovery mode (but i can access the bootloader). when i try to access recovery mode a page appears that has its its first line as follows

start do md5 checksum.

then the below lines appear in red

And one more thing ,I think i reached this glorious stage during a supersu unroot.WILL his lead to any more complications?

Please help. Being like this feels like forever. I am living in India so the chance of someone else knowing anything about this are very slim.

Thanks for the help in advance.

Since you're able to connect to bootloader, you need to flah the stock recovery then flash the stock firmware. This tutorial explains it better.

Go here to get Minimal ADB and Fastboot. Open it and run commands. You must CD to the folder containing the files to be flashed. Exemple: CD C:\Downloads\my_stock_firmware
and tape commands from there.

Same error here for me with my OnePlus 3.. "cache : failed. boot : failed. boot_aging : failed. system : failed. md5 checksum failed."

No decimal input on numeric field when using Google Sheets on phone In Google Sheets, when I add a number (e.g. 1.01) using the text keyboard and hit Enter, this numeric keyboard pops up as a default because the field is numeric. However, I do not have a decimal option, so I switch back to text keyboard, and we start over on every cell... or I could switch back and forth just to get the decimal, which is also insane.

On a tablet, in the white (extra options) the last one is the decimal point, but on the phone, it isn't there. I'm using Samsung Galaxy S3 and there is no decimal point on numeric keyboard.

How to input a decimal point with numeric keyboard?

Screenshot (click to enlarge)

There may not be an exact solution to the problem as you posted it, but there are possible workarounds. Android's primary strength is it's customizability and modularity, so if one (your stock) keyboard does not satisfy you, you're welcome to switch it out for another which does.

I know of 3 keyboard apps off-hand that have a decimal point in their numeric keypad. These are:

Google Keyboard - The officially recommended keyboard app for Android, and the default for Nexus devices and devices running Lollipop or above (as the AOSP keyboard). Very clean and doesn't deviate much from AOSP. Completely free.
SwiftKey Keyboard - a very popular keyboard replacement app (some might even say the most popular). Highly themeable. Free with in-app purchases.
ai.type Keyboard - Another very popular keyboard. Supposedly has very good text prediction, and also high themeability. Free with in-app purchases, Pro version removes ads.

I recommend these keyboard replacement apps to the OP as I have used them myself and know that they (when I used them) provided a numeric keypad with a decimal point, as the OP requires.

This was fixed after app software update


Where has all my storage space gone? This is actually starting to annoy me!

Every so often, I get the 'Storage space running out' notification. I go into my settings, and it says I have 60MB left.

The thing is, almost a month ago I erased the device because of the same thing - I have my 1.8GB available, and everything was fine and dandy, until now.

I haven't installed anything recently, however I suddenly only have 60MB left. I added up all the app sizes according to Android:

Chrome - 65.55MB
Can You Escape - 34.75MB
Facebook - 31.77MB (why does Facebook use so much?)
Gmail - 27.46MB
Skype - 24.04MB
Facebook Messenger - 19.74MB
Search - 18.98MB
Tapatalk - 17.50MB
Hangouts - 17.33MB
Maps - 13.49MB
Google Play Services - 13.49MB
Google Play Store - 10.91MB
Youtube - 10.80MB
System - 10.27MB
Google+ - 9.39MB
Shazam - 8.37MB
Titanium Backup - 8.30MB
Spotify - 6.93MB
Ingress - 6.70MB (I still have 3 invites if anyone is interested)
Media Storage - 4.50MB
3G Watchdog Pro - 4.05MB
Cerberus - 3.02MB
Secret Codes Revealer - 2.99MB
Email - 2.93MB
Contacts Storage - 2.62 MB
Super SU - 2.50MB
Screen Standby - 2.27MB
Settings - 2.20MB
Titanium Backup Key - 2.12MB
DeskSMS - 2.09MB
Exchange Services - 2.05MB
Browser - 2.05MB
Root Explorer - 2.03MB
TalkBack - 2.02MB
Beats Audio - 1.90MB
Google Services Framework- 1.86MB
Google Text-to-speech - 1.78MB
Gallery - 1.75MB
Spirit UL - 1.66MB
Contacts - 1.65MB
Spotify Community - 1.53MB
Sound Search for Google Play - 1.34MB
I then have ~80 apps < 1MB in size.

Add them all together, and I get 490.53MB - nowhere near the 1.9GB Android says I am using.

Why is Android reporting me using 1.9GB? What is using this memory? Why isn't it showing in the settings?

And above all, how can I fix it?

I am using a Samsung Galaxy SII with Android 4.2.2 Cyanogenmod 10.1

I use DiskUsage for situations like this. It graphs the directory structure for you in a very pedagogical way to show you what directories (and subdirectories) that are taking up the most space. It literally solves situations like this in 15 seconds for me, because I'll see a big square with the text "Movies" or something on it, realizing I completely forgot I put an entire season of Wonders of the Universe on my device or something — or I'll se a folder with a name of an app that has long since been deleted with a bunch of useless cache :)

Try it out, I'm not sure how well it works on non-rooted devices but I think it should work on those as well, I don't think it does anything else than list directories and add their content size up.

In settings, superuser, you can switch off logs


Will flashing a custom fix lag on my Android? I have a 1 GB RAM tablet running a pretty much vanilla Android Jelly Bean 4.1.1 and it's been running very slow. Apps startup time have been slow, noticeable lag exists while scrolling between the home screens, and apps crash sometimes. Browsing on the Internet has scroll lag and I have many more problems. I know that 1GB of RAM is more than enough to run Jelly Bean smoothly without any lag. How will rooting my device or flashing any custom ROMs help? I am new to the Android world, any suggestions are welcome, thanks.

Im not sure about the hardware of your tablet ,so might not be that powerful .That could be the reason for the lag
About rooting and custom roms they are not assured to remove lag  ,some roms might help while some may be even slower, it depends on the rom You use .But that said generally custom roms are made to be lightweight ,fast and fluid.


How do I get Android-x86 (32-bit or 64-bit) non-UEFI to boot in VirtualBox? EDIT: I'm getting similar results in both 32-bit and 64-bit.

Summary

I am installing Android-x86 version 7.1 32-bit or 64-bit in VirtualBox.

If I install it using UEFI (64-bit only), it works, but I cannot resize the screen, a problem to which I have been unable to find an answer.

Therefore, I need to install it without UEFI, so that I can resize the screen.

Problem

The Android installation runs smoothly. But, no matter what I have tried, once installed, the non-UEFI Android system won't boot.

If I use a GPT hard disk, I get this error message when booting the newly-installed Android, whether 32-bit or 64-bit:

FATAL: No bootable medium found! System halted.

If I use an MBR hard disk, I get this error message when booting the newly-installed Android 64-bit:

  Trusted GRUB now booting command list

  Progress:
Error 15: File not found

tGRUB: ******************************************
tGRUB: * An error occured which might result in *
tGRUB: * an unverifiable or insecure system     *
tGRUB: * state. !!! BOOTING WILL BE STOPPED !!! *
tGRUB: ******************************************

And the 32-bit starts with 100% CPU and goes nowhere (very fast!).

More information

Host

Linux Ubuntu version 16.04 64-bit
VirtualBox version 5.1.28

Guest

Type Linux, Version "Linux 2.6 / 3.x / 4.x" (32-bit or 64-bit as appropriate)
System Base Memory 2,048 Mb
System EFI turned off
Storage

Controller: IDE for the optical drive to hold the Android-86 ISO
Controller: SATA for a 40 Gb hard disk

Question

How can I get Android-x86 to boot on a non-UEFI system on VirtualBox, please?

When you try to install Android x86 on pc HDD, try to provide a boot partition through Create/modify partition and make it bootable. Followed by that create a new partition as Linux. write both the partition and after that install the android x86 on the linux partition (formatting as ext4).

It will work, after allocating a bootable partition. I tried and it worked.

Ways to call with Google Voice without mobile service and hangout? Are there ways to make and receive calls with Google Voice on Android 4.4.2 and Kyocera Hydro Icon,  but without mobile service and Google Hangout?

My Google Hangout has some problem, for which I am still looking for solutions.

My mobile service's signal isn't great in my apartment. So I am trying to use VoIP over WiFi.

Thanks.

you can use Grooveip app or Ringto app which is an alternative to hangouts and works same like hangouts.


How do I lock my bootloader again? I tried to root my Moto G3; but I was unsuccessful. Now my phones boots with this warning.

I am sick of seeing this on boot screen. How do I disable it? Seems like I need to lock the bootloader again. How do I do that? I'm completely blank.

First, I want to tell you that relocking the bootloader will NOT get rid of that message... On the Moto G3, once the bootloader has been unlocked that message will always appear, forever. That being said, you can flash a custom boot logo to cover the warning. I will explain how to relock the bootloader and fix the logo though.

To successfully relock the bootloader on a Moto device, you must flash a complete stock firmware image via fastboot that is of the same or newer revision than you have installed, you cannot downgrade to relock. Firmware images are available here and vary by exact model. Once you have that unzipped and in your fastboot directory, perform the following commands:

fastboot oem lock begin
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash system system.img_sparsechunk.5
fastboot flash system system.img_sparsechunk.6
fastboot flash system system.img_sparsechunk.7
fastboot flash system system.img_sparsechunk.8
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot erase userdata
fastboot erase customize
fastboot erase clogo
fastboot oem lock
fastboot reboot

Note that the number of sparcechunks can vary by model and Android version from 5-11 pieces, but what you flash must match the firmware image you have. If any piece fails, the bootloader will not lock.

Once this is done, you will have a completely stock device and a relocked bootloader, with a nice Bootloader Unlocked warning screen. As I said, once the bootloader has been unlocked, it cannot be restored to it's original condition in any way we know of.

To get rid of the screen (but not the delay or vibration, we can't get rid of that) you can flash a patched logo.bin file in fastboot. This can be done even with a locked bootloader. This can be done by flashing the logo.bin file from this ZIP file with the command:

fastboot flash logo logo.bin

And the warning screen will disappear. The ZIP file can also be flashed in it's entirety via TWRP recovery instead.

All of this may not be relevant, since rooting this device is very simple, since that wasn't your question I will not answer it here, but I will point you to my thread on XDA which may be of assistance if you want to attempt rooting again. Note that the logo.bin file I reference above can be flashed on a stock or modified system to get rid of the warning, your bootloader does not have to be locked to get rid of the warning.


Does Samsung Galaxy S keep GPS location in camera taken photo metadata? Does anyone know if Samsung Galaxy S GT-I9000's camera taken photos keep information about GPS location from when they were taken?

Thank you

It can if you turn the function on in the settings.  In the settings menu there's an option for "GPS", that when checked turns on geotagging:

via GSM Arena & CareAce

I just did a reset of all camera settings and the geotagging disappeared. Since this is what I wanted, I'm happy. When I bought it it was off (I think) and it got turned on sometime last month.


How to delete contacts from read only accounts I am using android, and the I have used my google contacts to sync to this, when trying to delete an account, it shows "You can not delete contacts from read only accounts, but you can hide them",
When I search the net, I have seen answers like 'clear the contacts and dialer app and again sync'
and doing so every time I lost the call history.

So now if I want to delete a contact in my phone, I first go to google contact and delete from there and again sync.

So if we want to delete an contact from contacts in google do we need to delete this from google contacts and again sync?
How can I delete a contact in google contact from android phone?
and if we hide the contact in phone, where can I see hidden contacts?

thanks,

as far as I know, these "read only accounts" relate to other accounts you have set up in Android (e.g. Facebook, WhatsApp, Viber, etc.). These accounts are (usually) synced by default when you set them up and the respective contacts are displayed in your contacts. You have several options to manage these contacts:
1. in Android under contacts go to settings and select "Contacts to display" - here you can chose which account to include in your contacts list. You can also chose a mix of them under "Customize"
2. to manage 'read only' accounts, you may go online to your respective services (e.g. Facebook, WhatsApp, Viber, etc.) and add/modify/delete the contacts there.
3. the best way to manage your Google accounts, at least for me, is still to edit them directly in your contact list at gmail.com.

Hope this helps a bit.

I got fed up working around it, I just deleted whatsapp add (in my case its what was linked) then deleted the contact and added it with the right info I wanted to be saved. then just reinstalled the whatsapp app and that's it
be aware when you are adding this person again to your contact list it may prepolute old info like G+ account so i deleted anything but the email and the phone number to make sure I keep the right info


Is there a ODIN or heimdall varient on Xperia? This one is what it says on the tin is there a form of ODIN and similar clients that have the capability to flash Stock and Custom ROMS to a Not boot loader unlocked device. I prefer if its built in Linux, but I don't mind using wine

Using Sony Xperia E C1505, android 4.1.1
Small note- if it relies on ro.product.name or the android version to detect a device,  no can do. I will accept universal flashing tools too.

Yup for Sony experia devices it is called Androxyde Flashtool
-Flashtool is a software used to flash Sony [Ericsson] Xperia line (2010 to 2013) phones that use the S1 protocol

How to transfer files from an Android phone to a Ubuntu PC by using a USB cable? Im completely new user and inexpert. I made a video with the phone. How do l transfer it to an ubuntu pc? I plugged in the usb cable but apparenntly my pc does not see the phone. Thanks for help

First of all you don't need any USB cable.
You can transfer files from/to your android device with the Wi-Fi network of your device. Just install airdroid on your android device. Then activate wi-fi hotspot on your android and open the airdroid app. Next connect your pc to that hotspot, open any browser in your pc and enter the url provided by the airdroid app there. It will ask for your permission, click to connect. Done.
   The good news is that this technique works in any Linux distro as well, I tested it on Ubuntu 14.04.1. It just uses your android wi-fi device and there is no issue related to mobile data plan i.e. you can use it without the mobile data.

Consider using gmtp. Although advertised as a media player, it is an effective tool for transferring files via MTP.

sudo apt-get -y install mtp-tools mtpfs gmtp

and try to use its GUI as necessary!

How to prevent someone from powering off an android device? I have a Nexus 5. Even if I enable security passcode or pattern, someone can still switch off my mobile using the power button. How can I prevent it?

You cannot (barring any hardware tweaks.)

If you root your phone and install a custom ROM, you may be able to remove the "Turn off" and "Reboot" options from the Power menu. However, Nexus 5 (as do most modern phones) has a hard-wired feature, where holding the power button for 10 seconds shuts the phone off.  This is done so that you can restart the phone if it freezes up.  Since Nexus 5 doesn't have a removable battery, this hard reset would be the only way to shut it off without having to wait for the battery to drain.

If you are technically inclined, you can always make hardware modifications to the phone which would prevent the Power button from functioning normally.  However, such mods are not for the novices, and will certainly void your warranty.

Just root your phone and buy Cerberus. They got this option.


How to remove "Scrapbook Photos" from stock Gallery? A folder named "Scrapbook Photos" appears in my gallery app, but whenever I try to delete it, it remains. It doesn't contain any items, trying to navigate into the folder simply redraws the main gallery screen.

How can I remove this nuisance?

You can delete it at picasaweb.google.com.  (Click on the album, and then use the 'Actions' dropdown list.)

I would find the folder through usb mode or a file system explorer such as X-Plore and delete the folder manually. Then it should be removed from the Gallery.


What is a safe CPU speed for the HTC Dream? I know that T-Mobile clocked it down to 384 to extend battery life on the G1, and I believe that the processor was designed for 528. With all that said, does anyone have experience with what a good, safe speed is?  I'm new to Android (less than 1 week), so all this is new to me.  Thanks!

Update: the processor is the MSM7201A.

It depends on your needs:

Do you want to conserve battery?  Then underclock the CPU
Do you want better performance?  Then overclock the CPU

Typically there are different kernels that you can flash for your device.  Different kernels offer different clockspeeds.  Some of them will also under volt your phone to consume less power.  The disadvantage of undervolting is that the phone may not be able to run faster clockspeeds.

Additionally, your phone may not overclock to the same speed as another phone due to one processor being physically different than another processor (no two processors are made 100% exactly alike.  When overclocking you are stepping beyond the bounds and specifications that your phone was designed to run at).  What will happen is your phone will enter a boot loop if it is unable to run the kernel at a specific speed (you'll have to flash a new kernel or revert to a previous Nandroid backup).

I don't know of specific kernels for the G1, but for example there is a set of kernels by ChevyNo1 for the Droid1.  The general steps are:

RUN A NANDROID BACKUP
Choose a voltage: ultra low, low, or normal
Start with the kernel with the lowest overclocked speed
Flash that kernel.
Use SetCPU to set the clock speed to the max.
If the phone remains stable, then choose the next kernel with the same voltage with a slightly faster clockspeed and try to run it at its max speed.
If the phone does not remain stable, then revert to your last Nandroid backup or the last kernel that ran stable on your  phone

I on battery mine is unstable at 633 MHZ on Froyo by laszlo kernel, but on charger it works. Using 595 is stable, you can set it in performance settings, you don't need app with this kernel. I set Minimal on min 122.

As I know this MSM7201A has 2 cpus, not changing frequency, but rather switch between cores.(found this information on Wikipedia) I have this old telephone and found it a bit hard to operate sometimes, but its still powerful enough to run most applications needed, and with those applications on SD ext I can perform almost anything, but the battery life is a bit small. But lets say its first android telephone(2008), full qwerty and lot of fun making it operate.


Sim card not detected after installing CM13 (unofficial) on xperia l i'm new to android. I recently bought a xperia l phone from my friend in which he had Cm11 installed i decided to upgrade to cm13 and it really messed up the phone.. the sim card was not detected and play store didn't work!!! so i came back to cm11 which then entered boot loop. So i decided to go with cm12.1. Now the pay services work like charm... BUTTTT sim not detected problem still persists!!! so can some one here gimme the link of the radio or modem files of xperia l c2104 or help me with any other solution for this problem... thanks in advance

Your baseband was messed up. Try to flash the stock ROM and don't flash CM13.

This happened on my Samsung Galaxy A3, when its baseband was messed up when I try to install it.

Yea flash stock rom of xperia...(model)..via download mode...
You need PC
Qpst installed on it&
And to go in download mode press volume+&volume- then connect the USB cable


Can't connect tablet to VPN I have two android devices, my phone and my tablet. In the country I live in some websites are blocked, which make some applications useless since they depend on internet connection. I tried in my phone downloading Kepard and the application works just fine, I can access any website. The problem is when I download the same application in my tablet (again, is android). And it doesn't work, I try many other VPN applications, Hotspot Shield, Hideman, hideninja, etc. and none of them worked.

I tried another Tablet (Android), installed Kepard and... It worked!. And I reached the conclusion that my tablet is the problem, and I would like to solve it, but don't know how.

Thanks.

I had the same problem using psiphon and hotspot shield VPN, after rooting my device I tried using psiphin and it worked.


Lost Android phone , Google is Forcing to Change Password but how to remote wipe it I lost my phone today and I tried to do the remote wipe several times because phone was off and I was impatient.
Now google says there was suspicious activity with my account and I must my password. This is the dilemma for me now.
If I change the password, I may not be able to get the remote wipe but there were 6 notification emails in my mailbox confirm remote wipe has been requested and then google locked me out.
Please help.
Thanks.

Well, if the thief connected to the internet, it would surely work.

You'll need google account which have registered in your lost phone. Search android device manager and follow the instructions.


Connect physical Android Wear watch to emulated phone I have found many tutorials that explain how to pair an emulated Android Wear watch to a physical phone. However, I would like to do the opposite. Is it possible to create a Bluetooth connection from the pc to the watch and then tell ADB to make the phone emulator use this connection?

You can't is the short answer. The emulator does not support bluetooth testing at all.

See the Google Developers post on Using the Emulaor

The important line is near the end:

Emulator Limitations

The functional limitations of the emulator include:

No support for placing or receiving actual phone calls. You can
simulate phone calls (placed and received) through the emulator
console, however.
No support for USB connections
No support for device-attached headphones
No support for determining network connected state
No support for determining battery charge level and AC charging state
No support for determining SD card insert/eject
No support for Bluetooth

As far as I know, the Android Wear service on the handset integrates many services to make connecting a watch to the Android handset easy. If you want to connect the watch to your computer, you'll have to replicate this code on the PC. As far as I know, Android Wear is not completely open source, so making that work might be impossible.


Why does video screen get brighter and how to prevent it? This happens on Nexus 7 2013 (Google stock 5.0.2) and also happens on Galaxy Note 12.2 tablet (Samsung stock 4.4.2). I am in a dark room. I have set the system brightness to the minimum (let us call this brightness MIN). To change brightness I use swiping up/down on the left screen area.

With MX Player, when the video starts playing, even the minimum brightness (which is 0) makes the screen brighter than MIN. There seems to be no way to set the brightness to MIN. I can clearly notice that the screen has been brightened, by pressing the home button or the task switch button. I can see that the screen remains bright for about 1 second then changes back to MIN.

With VLC, when the video starts playing, if its previous brightness was 0, the brightness does not change and remains MIN. But if I change brightness once, changing it to 0 does not lower the brightness to MIN. At this point, VLC acts just like MX Player.

Is this a bug of Android? It seems as if the system passes a false minimum brightness of the hardware to the software. Is this an intended behaviour to make video brighter? Anyways, is there any way to prevent this brightness change? This hurts my eyes when I watch videos in a dark room.

==PS==

This behaviour is also happening in CyanogenMod 12 (Android 5.0.2).

You can disable MX Player's brightness controls. To do this, goto Settings>Player>Screen and uncheck the brightness option.
And, an alternate option is to use an xposed module(you need a rooted device) named Minimum Brightness.

This is a screen filter app that I use with all my devices. Its called Darker. It has not only absolute min brightness, but it also has an option for a color as filter. Useful in low light; ie. android LED lighting is blue in light spectrum, using a red filter compensates - so eye strain is less, sleepless nights are less (my opinion and I'm not a doctor, but these are my own observations). Color and brightness filter can be used independent of each other. This can be used with or without root.

Android won't let you install apps when screen filter is active (security measure against malicious attacks), because it is an overlay on the screen.


Lock screen won't reset to swipe from numeric My Galaxy Note 3 won't go back to swipe to unlock the home screen after I set it to a numeric code. I see a note on the screen that says "Android device administrator has turned off the...." or something to that effect.

How can I remove my numeric lock and go back to using a swipe to unlock? Would unlocking or rooting help at all?

There are a number of reasons why you may not be able to downgrade to a swipe-unlock.

Exchange Email

If you have an Exchange email account set up, many times the Exchange admins won't let you connect unless your phone agrees to certain security precautions, such as setting up an unlock code.

Solution: Remove the account, or install an Email app that lies to the Exchange server, saying it is compliant when it really isn't.

Device Administrator

Check in Settings->Security->Device Administrators to see if there are any active apps listed. One or more may be requiring an unlock code.

Solution: Uncheck the apps listed. Note that those apps may no longer function properly.

Device Encryption

Not applicable in your specific situation, but enabling Device Encryption will also prevent you from removing a screen lock.

Go to Settings → Security then hit Clear Credentials.


how to transfer a file from within system partition on android to desktop background

I'm developing an app that downloads files to the device.. some of these files are acting out and to trouble shoot I want to actually transfer these files to my (mac) desktop and go through them.

So this is what I did:

i rooted my device
i know exactly where my file is:

$adb shell
$su
cd /data/user/0/com.app.name.dev/files/34234/
ls

here i get the file name.. let's say it's called
file_name.txt

the problem is when i go to my desktop and do something like

adb -s $device_id pull /data/user/0/com.app.name.dev/files/34234/file_name.txt

i get the error message

remote object '/data/user/0/com.app.name.dev/files/34234/file_name.txt' does not exist

when i know it does!

I also tried using scp from within the android shell command.. but scp doesn't exist there
i tried running adb root and got

adbd cannot run as root in production builds

any help?

it turns out that i simply should use the cp command from within my root android shell.. and copy it to /mnt/sdcard.. the rest is obvious after that


How can I recover files from a phone that won't boot? I have a Galaxy SII, and it is stuck on the boot screen. How can I recover the files on the phone?

I had the same problem with stock Nexus 7 2012 GSM.

The relevant documentation for this is

https://support.google.com/nexus/answer/4596836?hl=en the Recovery mode section
https://developers.google.com/android/nexus/images section Flashing instruction (it helps you get familiar with adb and fastboot)
https://developer.android.com/tools/help/adb.html ADB manual

First of all, the bootloader has to be unlocked.

fastboot oem unlock

Unlocking the bootloader deletes user data on the device (as a security precaution). If you haven't unlocked the bootloader before, you are now out of luck. Try to find if you have backups. (Contact data may be synced with your Google account, you might have Dropbox installed, G+ backups photos and so on).

Assuming unlocked bootloader, you can flash a custom recovery which will allow you to access data on the phone.

I tried ClockworkMod, but after I booted into it, adb listed my tablet as unauthorized device, similarly as this person describes. He solved the problem, I did not.

Therefore I next tried TWRP recovery.

fastboot flash recovery path_to_twrp.img

With TWRP, adb devices listed my device with recovery permissions (whatever it means) and I could copy out my data

adb pull /data .

In addition TWRP seems to enable MTP on the device. That is another possible way to get data out. I haven't experimented with it, because I did adb pull first and I got my data that way. Additionally, in my experience, MTP clients for Linux are rather flaky.

You will need the Android SDK and your phone's appropriate drivers so you can use Fastboot ADB and pull the files manually. Here's how to get into Fastboot mode:

Pull battery and reinsert
Hold VOL DOWN, press and release PWR button (continue holding VOL DOWN)
You should see a menu with the following options: Fastboot, Recovery, Clear Storage, and Simlock; select Fastboot.

Here is a fantastically detailed guide for how to recover files (post #22):

http://www.galaxyforums.net/forum/galaxy-s2-help/6232-screen-cracked-need-recover-very-important-data-3.html

To address the custom recovery question: if the OP is running 4.2, he/she is most likely running a custom ROM and therefore a Recovery, as the latest official build from Samsung for this device was 4.1.2 (at least on the Sprint and AT&T versions).

Hope this helps!


Can i flash indian rom in korean galaxy note? I got the Samsung Galaxy Note shv-e160l (Korean version) as a gift, running the stock ICS 4.0. I want to flash official indian JB ROM (of the GT-N7000) on it. Is it possible if I root my device?

No, do not try to do this, or you will brick your device. SHV-E160L and GT-N7000 have completely different processors (Qualcomm Snapdragon APQ8060 for SHV-E160L, and Samsung S5PC210 for GT-N7000); e.g., see this comparison.

There are some custom ROMs for SHV-E160L in the xda-developers section for AT&T Samsung Galaxy Note I717 (this device is closer to SHV-E160L, but also not 100% compatible, so look carefully and use only ROMs which are made for SHV-E160L).

No, you can't run the Indian ROM. Both are different chipsets, and forcing it might brick your device.

Many users requested the SHW-M180S Firmware. I have uploaded it here.

It is only for the SHW-M180S tablet.


Does Android have support for IPv6? I wonder if Android has support for IPv6? I have heard that the phone company I use has support for IPv6 and I have a IPv6 address if I visit http://ipv6.whatismyipv6.net.ipv4.sixxs.org/.

But I can not visit IPv6-only sites like http://ipv6.google.com, why is that? Does Android have support for IPv6?

As of Android 6.0, the majority of the IPv6 protocol seems to be supported with significant parts missing such as DHCPv6.
Check Issue #36908577 Support IPv6 for more info, specifically the issues listed in comment #105:

Enhancement: Support for DHCPv6 (RFC 3315) Won't Fix (Intended behavior)
http://code.google.com/p/android/issues/detail?id=32621
Enhancement: Support for Recursive DNS Server Option in ICMPv6 Router Advertisements (RFC 6106) Fixed
http://code.google.com/p/android/issues/detail?id=32629
Enhancement: Support connecting to IPv6-only wireless networks Fixed
http://code.google.com/p/android/issues/detail?id=32630
Defect: APN Protocol ignored when roaming Fixed
http://code.google.com/p/android/issues/detail?id=32631
Enhancement: Automatic fallback from IPv4/IPv6 APN Protocol to parallel IPv4 + IPv6 Won't Fix (Obsolete)
http://code.google.com/p/android/issues/detail?id=32632
Defect: Frequently ignores ICMPv6 RAs and other multicast traffic Won't Fix (Obsolete)
http://code.google.com/p/android/issues/detail?id=32662

(Consider reading the issues and their comments carefully, because while some of them have their status updated to "fixed", some users were reporting they still have the same issues.)

Android 5.1.1 supports IPv6.
Here you han a screenshot of the console ‘netstat’ command (https://twitter.com/juan_domenech/status/732535218662412288).
You can also check this typing ‘what is my ip’ on Google and observing whether you have an IPv4 or an IPv6 coming back (only in IPv6 WiFi networks obviously).
Turns out that DHCPv6 is not necessary after all (SLAAC might be in place here).


Can't factory reset my Galaxy S20 I'm trying to factory reset a Galaxy S20 because I've forgotten to add MDM in the intial setup and as far as I know you can't add this later.
To do the factory reset I've done Settings > General Management > Reset > Factory data reset. Then tap Reset and Delete all. But it then asks me to confirm my Samsung Account which it somehow can't do, because I always get a loading icon which fails after some time. Then it asks me for the password of my Samsung Account and again goes into a loading icon which also just stops after some time. I don't get any error message.
There's also the option to send a confirmation e-mail, but this also leads to the loading screen but after some time I get a little pop-up telling me there is a network error. The screen here stays white and I need to use the back button to go the confirmation screen of my Samsung Account.
I do have internet access on my phone, because I can open websites with Chrome. I'm using my home Wlan Network to connect to the internet.
I didn't find any solution to this problem with Google, just the normal documentation from Samsung of how to factory reset a phone, which doesn't work for me.

The solution to my problem was that somehow my phone couldn't access the Samsung Account site over my home network. I've switched to a hotspot of my other phone, and now everything is working as it should. I was lead to this solution because I've seen other people having problems with accessing the Samsung Account site. Perhaps some providers have problems with this.

There is a sort of recovery mode called EDL, the new ODIN mode.
As you are using a samsung phone, download galaxy S20 firmware (you need to type somewhere the phone e.g. SM-G530FZ Galaxy Grand Prime phone code), and downlaod Odin.
Shut Down completely your phone.
Press volume down button until connect your phone to pc, and the phone should be recognized  by ODIN.
Else if it's not, Download some EDL Utility.


Play a live YouTube stream in the YouTube app For example youtube.com/opener - it won't play via the browser, but I can't figure out how to access it via the app.

Is it possible?

You can't. This feature was added in the ICS version of the YouTube app. Older versions don't support it.

You can use the browser.

Just type the livestream link, and it will load normally. On the downside, it will lag a little bit.


Change the language back from Chinese to English on Samsung Galaxy Tab 4 My grandson used my Samsung Galaxy Tab 4 and now the language is all in Chinese. What do I have to do to get it back to English as I do not read Chinese?

Go to:

  Settings > My device > Language and input > Language

then set any language you want it to change the menu language. Should be similar to this, just find this icon and follow it step-by-step.

you can also try go to MENU < SETTINGS < LOCALE AND TEXT < SELECT LOCALE and choose your language. For more details you check in support option of Samsung India site.


Strange (unfamilar screen) on my Galaxy Tab? I have a Galaxy Tab 10.1.  It was powered off and charging when my nephew picked it up and turned in on.  When he handed it to me on the screen was a graphic of an open box, the android logo with the words downloading.

It has been in this state for 4 hours now and I cannot switch the device on or off.  Please help me understand what has happened and what I should do.

Your device is in Download Mode. I don't have that device, but if the battery doesn't come out, you will probably need to use ADB and send an adb reboot to get it out of Download mode. If you don't know how to use ADB, then you can just let the battery die. I don't like that option though because the same image will be on the screen for an extended period of time.

Does the screen look like this:

To use ADB:

Download the USB Drivers from Samsung
Download the Android SDK
connect the device to your computer via USB cable
open a command prompt where the Android SDK was installed and change to the platform-tools directory. for example, my sdk is installed at c:\android-sdk so I run the following:

C:\android-sdk> cd platform-tools

then try to reboot with adb:

C:\android-sdk\platform-tools\> adb reboot

if that doesn't work try the following command:

C:\android-sdk\platform-tools\> fastboot reboot

I don't own a galaxy tab but some tablets have a hard reset button similar to windows power reset button. It's generally a small hole  and you can use a pin to reboot the device by pressing  the pin in the hole for few seconds. Basically what it does is it reboots the tablet. You don't require to wait for the battery drain.


Images deleted after taking taking memory card i used 2gb memory card for 5 months in my HTC mobile, i have unmounted it and removed it safely to replace it with 16gb. but now when i try to connect the 2bg card to system and copy the images through adapter, they are lost...every other data is there except the Pics which i took using camera. please help me to recover that pics

If you have not overwritten the data in the 2GB memory card, then you can recover the pics using "Recuva" in Windows PC. The software is available for free download online. Install the software, connect the adapter, select the drive through the application's interface and you will be able to recover the pics.

If you have to many  pictures they show  blank  so you should  get a picture program that allows you to make stalks of your pictures to  save room and more  can be keep  on the phone that way


Factory reset is disabled by kill switch on LG L16C I cannot do a factory reset on a LGL16c, it comes up with screen to confirm reset and agreeing to wipe data, I say yes to both. Then it comes up with a screen that says

  Factory reset is disabled by Kill switch

I reboots and nothing happens. I cannot reset through settings on phone, security, it says factory reset disabled by server policy.

I found out that all new smartphones have this new "Kill switch" installed by all manufacturers because a new law passed prevents a thief from accessing a phone if there is a password on it and trying to factory reset it.

Is there a way to bypass the kill switch if I have the phone and there is no password and I want to wipe data and reset phone?

"Killswitch" wouldn't allow me to turn on my usb debugging yet, I was able to bypass "Killswitch" by using Android Device Manager and wipe my phone as if it was lost or stolen. Which in turn reset the phone "LG L16C".

Well, I have had a lot of experience with android devices, and I might have found a solution:

If your device is rooted, and you haven't already gotten your phone locked, you can get a "bloatware" remover, find com.android.systemUI.factory.KILLSWITCH.apk.ODEX and remove it. I hope this works!


Selecting multiple photos on the HTC One X (AT&T) I just received the HTC One X from AT&T. How can I select multiple photos in the Gallery?

My experience of the One X in order to be able to select multiple items in the gallery you need to first give it a task to do.

For example,

Open Gallery
Hit 'Share' in the bottom left, you'll need a service which takes multiple uploads, such as Facebook
Then you'll see the 'multi-select' grid with tick boxes next to each image which you can then select.

As far as I can see from playing on my device for 10 minutes, there isn't a general 'multi-select' feature. You might try a different gallery app though. I would recommend QuickPic

I think multiple selection is (Programmatically) supported in KitKat and newer versions of Android as given in this link.


Turn on HotSpot via ADB -- Sony Ericsson Xperia mini ST15i How to turn on wifi hotspot on ST15i via ADB? There is already on post about this using keyevents but it does not work for me. It has hot broken touchscreen, back is always clicking, but before, I turned on USB debugging so ADB works. It is not rooted. I want to use it as mobile hotspot from SIM. It has Android 2.3 GingerBread.

Try this:

/system/bin/hostapd -e /data/misc/wifi/entropy.bin /data/misc/wifi/hostapd.conf


"Can't reach Google at the moment" when using Google Now I have Nexus 4 running on Lollipop 5.0. Everytime I input a command via voice, or typing to set a reminder in Google Now, I get

  Can't reach Google at the moment

I've changed languages from English (US) to English (IN) with no results.

Does anybody know a fix for this? Alternatively, is there another way to set reminders via voice command just like Google Now?

I had issue with reminders not working and that was "fixed" by going into app settings and then Accounts & Privacy, turn ON Search with Google.com

Now commands work properly? Must be a local server issue.

In Google now cards...Settings>Now Cards>Delete card preferences

This will disable now cards.

Re-enabling will bring it back.


Go Sms Pro: "Too many unsent multimedia messages" error Every time I try to send a Multimedia message using Go Sms Pro, I get a
toast message saying: "Can't send message right now. There are too many unsent multimedia messages"

This doesn't happen when I send something through gomms (which is really only good for sending to other people with smartphones), and it doesn't happen when I use any other sms/mms client (like handcent or the default sms client). It only happens when trying to send an MMS message with Go SMS pro.

How can I get this to work? I would have thought that if this was a global bug issue, that it would have been fixed by now, so I am guessing that there is something I need to set/reset. What do I do to fix this?

This has happened to me at least once before. Very annoying. In my case I had to check every thread, and scroll up to look for failed mms messages in the thread(red !). Once one fails, apparently nothing else except regular txt will go through until the offender is deleted for some reason. I think I narrowed it down to a message I sent from my garage. With the doors shut and if I'm in the back, I get one signal bar if I don't move. I think I attached a pic, hit send, then stuck it in my pocket while it was trying to send. Why it doesn't send later when i get a better signal is beyond me. But, by checking all my threads, and deleteing each one the had a red ! eventually I was able to send the one I really needed to send. If it happens again, I'll update the post with more solid information.
Phone is G'zOne Commando, Android version 2.3.3 hope this helps someone.

I have a note 3 and had the same issues.

Go in your settings and check to make sure sms is your default.
Under the sms program is a setting to make sms your default as well.
Your default notification on your phone system needs to be turned off so that you don't have multiple notifications.

Hope this helps.


Hangouts Error on Android Phone: Cannot connect to the server I'm getting a "cannot connect to the server" error when I try to use Hangouts on my phone. Every other Google app works. SMS works but not Hangouts messages. All my other devices work with Hangouts messages.

It turns out that this issue is due to the restricted background data setting.

Navigate to Settings -> Data Usage

Find the following apps and make sure "Restrict Background Data" is switched off:

Hangouts app
Google Services
Google Play Store

Go to Settings > Apps > swipe right to "All" > click the menu button of 3 vertical dots > click on "Reset app preferences".


Odd problem with USB tethering: Error 324 (net::ERR_EMPTY_RESPONSE) or Error 102 (net::ERR_CONNECTION_REFUSED) I am accessing internet with my Laptop through 3G USB Tethering from my Nexus S with Android 4.0.4.

About half of the time, I lose connection and I am unable to access any website on my Laptop or use any application that connects to the internet (eg. ping), except for Gmail and Skype (which still work very well). And it goes back and forth frequently between the normal situation and the odd one.

If I try to access any other website on my laptop (like google.com), I get depending on the website:

"No data received
Unable to load the webpage because the server sent no data.
Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data."

OR

"This webpage is not available
Error 102 (net::ERR_CONNECTION_REFUSED): The server refused the connection"

Do you have an explanation for this bizarre behavior? Do you think an app is interfering with my connection?

Sometimes rooting may cause such problems.
The phone says "unrooted" or otherwise, bans some programs, i.e. browser, etc., from functioning properly.
I would suggest to apply a factory reset - of course after having all the back up you may possibly need - rather than flashing a clean firmware.


How can I make the browser remember login credentials for Google mobile sites? The stock browser forgets the username and password when logging into mobile versions of Google sites such as Google Search and Google Tasks. Setting Menu -> Settings -> Privacy Settings -> Remember form data and Menu -> Settings -> Security settings -> Remember passwords in the browser has no effect. Checking the "Remember me" checkbox at the sites' login forms has no effect either.  How can I get this to work?

I use a Nexus S running Android 2.3.6.

Webpages can opt out of autofill; intended to be added security for banks and other sites requiring higher than normal security. There are ways to circumvent this in firefox, chrome and IE but I haven't figured out how to do it for android. Whats the origin of the android browser code base? That might be another place to look.

Use an app called LoginBox. It's a browser that specialize in remembering the complete login process.


ICE Emergency Contacts on Emergency Dialer Screen On my Samsung Galaxy S 4, I can add contacts to the "ICE - emergency contacts" group. When I initiate the emergency dialer, there are four gray buttons with plus signs. Pressing any one of them brings up a list of the contacts I added to that group.

Each of the buttons acts the same. I would think that you should be able to assign one contact per button and have the button show a name or relation.

Is it possible to do this? How?

Once you hit the gray box & that ICE list pops up, I believe you just have to select a contact from that list in order to assign that person/phone number to the box.

Just be careful with assigning contacts to the gray boxes because it can be very easy to pocket dial these people. In case you're interested in removing someone from the gray box, you select the menu button while on the "Emergency Dialer" screen & it'll give the option to remove the contact from the gray box.

Hope it helps.

Go to Contacts → Groups and you will see a group named "ICE - Emergency Contacts". Add your emergency numbers there and now you can access them from outer screen.


System default camera app not showing up I am not able to find the system default camera app icon in menu on my GiONEE P5L handset (Android version 5.1). But the app is still on the phone and it's working as well. Able to take photos and videos. I want to show the icon in app menu. Someone please help me.

Open Google search and type "open camera"  then it will open


Whatsapp doesn't work over 3G,everything else works fine A friend has a factory fresh, unrooted Samsung Galaxy S Duos, and except for Whatsapp every other internet accessing app works fine on a 3G or EDGE connection.

She has un/reinstalled Whatsapp several times. It works fine over Wifi. She's no power user, so any solution involving rooting the phone is not an option.

To clarify - there is nothing wrong with 3G or EDGE on her phone, since she can browse the internet and use other such apps perfectly fine.

Update - She's on Vodafone, as I and thousands of people in India are, and no, Vodafone is not blocking Whatsapp for any reason.

Searching for solutions on Google only leads to 'No shit, Sherlock!' type answers with genius level solutions like 'check whether your 3G connection is working' or 'get the latest version of Whatsapp'.

So is there a workaround?

I faced similar problem until recently I found the fix. I use Vodafone 3G Pack.

If you are an android user, check the network and settings -> Access Point names
In that check if APN is set to Vodafone Live.
If yes, change it to default settings and it should be changed to vodafone Mobile connect.
Also, then check the value of MCC and MNC. It should be as per country code and mobile operator.

I didnt understand, why this changed on its own, but after making this change and rebooting phone, it worked for me.

I hope this works for you too..

I had a similar problem. Reset the APN settings to their defaults and it will start working.


Facebook contact sync no longer working: "Sync is currently experiencing problems. It will be back shortly" As of a couple of weeks ago my Galaxy S3 (running Android 4.1.1) no longer syncs contacts from Facebook. I have the Facebook app installed and calendar and the gallery are syncing fine but the contacts fail. I get the following message:

  Sync is currently experiencing problems. It will be back shortly.

Just to be clear, it did used to sync the contacts fine, but then the above started happening. I have updated the Facebook app a few times but I cannot remember if it started happening immediately after one of these updates. Anyone know what's going on or how to fix it?

Samsung phones have a proprietary app to synch with social networks: SNS Provider. So to solve it you probably have to search/wait for an update to it in Galaxy Apps.

You can also check your preferences in Facebook app, it has its way to synch contacts and gallery. There should be an option related to contacts synch, check that it's activated.

Try installing Facebook APK manually following this steps:

On your phone go to Settings > Security and check the "Allow unknown sources" check box
Download the latest (to the date of this answer) Facebook apk from here
After the download is finished, click on the apk in the list of downloaded items or go to /sdcard/downloads with a file manager app like ES File Explorer and open the apk file.
The installation screen should appear showing the permissions asked by the app. Click on "Install" at the bottom of the screen.
Wait for the installation to finish then click on "Open" to open the Facebook app.

Now you have the latest Facebook app - let's fix the Play Store issue:

Go to Settings > Applications > All. Search for the Play Store app and click on it.
The info about the Play Store will appear. Wait until the "Delete data" button is click-able then click on it and confirm.
0 Now go back to your same screen and launch the Play Store and wait for it to load your account, then go to the "My Applications" tab and you should see the Facebook app there (if it's not try rebooting your phone).

You are all set. You now have the latest Facebook version and it will be updated normally through the Play Store.


Wi-Fi connection dropping Lately I've been having trouble keeping a connection to Wi-Fi, first at home and now at work.  What happens is that after a while I'll notice that my phone is using 3G.
If I go into my Wi-Fi settings, I'll see a strong signal from my router. When I try to connect manually,  I often get the message,  "Failed to connect to network" with no further details.  (There's a special place in hell for those who write error messages that give no indication of the nature of the problem.) Other times I can connect,  but the signal is reported as weak and drops quickly.
My computers can connect with no problems and report strong wireless signals.  My roommates have no similar problems.
I have a Galaxy Nexus running Jelly Bean.  My roommates have a Galaxy Note and a Galaxy S2, respectively,  both on ICS.
What's wrong with my phone?
Additional details

My phone is rooted but running the stock ROM.
My phone is the international GSM version.
I first noticed this problem while using Tasker to implement a Bluetooth wireless leash. I've stopped using the leash--and Bluetooth entirely--but the problem persists. I'm still using Tasker for other things.
In trying to track down this issue, I disabled "Avoid poor connections" but that change had no effect.
I'm willing to consider flashing stuff to my phone as a last resort, but I strongly prefer alternative solutions. I didn't have problems initially, so I doubt the radio is to blame. Furthermore, I will down vote any answer that provides an incompatible ROM/radio, etc. or that provides it from a non-reputable source.

My solution, which seems to be working so far, is quite related to what was proposed by t0mm13b.

That proposal was to adjust the DHCP settings. However, my router is quite limited in functionality and it's impossible to adjust wifi settings on it. Insane, I know. So, I set my phone to use a static IP address instead of using DHCP. So far, so good.

There are newer radios out there that greatly improve the radios. https://dl.dropbox.com/u/19045917/411_radios.zip
Since you are rooted I assume you know how to flash radios.


Galaxy Tab 10.1 doesn't keep wifi connected despite settings My Galaxy Tab 10.1, 16GB Wifi only version, disconnects the WiFi whenever the tablet goes into sleep mode.

I have ensured that I have selected to never sleep in advanced WiFi settings.

I downloaded and experimented with the Wifi Keep Alive and REGPON wifi KeepAlive apps, but they have had no effect.

I even tried rooting the device, and put on this ROM, in hopes that maybe some change would take effect, but it hasn't.

Is this a known issue with the Galaxy Tab 10.1? I've done some Google searching and I've seen other people report it, but most fixes seem to just describe how to go into the advanced settings and enable "never" as an option.

Is there any kind of fix I can apply?

This is a somewhat critical feature for me, as I intend to be able to receive Skype calls, which can't be done if the WiFi disconnects.

In a nutshell: using a static IP is like owning a house.  Having a DHCP lease is like renting, but you may have to move when the lease is up.  Unfortunately, the Tab's implementation is like a renter who leaves, then tries to get back into his old apartment (which in this analogy is a dynamically assigned IP address on your WiFi network) and finds it locked.  Instead of asking for a new lease, it just keeps knocking on the door, never to enter.  In this case, it means that your Tab won't connect to your WiFi network on wake.

The detailed explanation: It looks like Samsung's implementation of DHCP lease renewal is at fault here.  When a device wakes up and then tries to connect to WiFi, it will ask for a DHCP lease (if expired), which also gives it a dynamically assigned IP address.  This works fine when the Tab first connects.  However it looks like it never asks for a new lease and thus new IP address.  Instead it caches the IP address and keeps trying to reuse it.  DHCP is dynamic so it means that any particular device on the network cannot rely on a specific IP.  So eventually the lease will expire and/or the IP address that the Tab is using gets reassigned to another device.  When this happens, your Tab cannot connect to WiFi.

So the solution is to assign static IP until the Tab's implementation of DHCP lease renewal is fixed.

An alternative solution is to root your device.  Then you can manually delete the cached file which contains the stale IP address following the instructions at: http://steve-shaffer.com/2011/02/samsung-galaxy-tab-wifi/ (where I learned about some of these details as well).  This will cause the Tab to renew the DHCP lease properly and live in a brand new and shiny dynamically assigned apartment on your WiFi network.

In Settings - WiFi - Advanced - Turn off "Always allow scanning" option.

It worked for me, WiFi is now stable.


Wi-Fi of Galaxy S2 is not working after ICS update! I updated my Galaxy S2 with the official OTA update to Android ICS 4.0.3

After the upgrade, my wireless worked for a couple of hours, but after a restart it doesn't work at all (for a week now).

I tried a couple of tricks (none of them working):
1) *#*#526#*#* combination
2) WiFi Direct activation
3) Static IP
4) Changing to 2.4 GHz

None of them are working!!!
Somebody has any other ideas?

BTW: I'm not getting an IP from my router. The router is working fine with other phones.

I was having the same issue for the last 2 days. After upgrading to ICS wifi was working but stopped working suddenly after a day. This is how it got fixed:

selected the network and clicked forget
turned off wifi
turned wifi back on
connected the wifi network again

same issue I had. Only thing that worked for me is restarting the router and then connect back to router. But the issue is that there's no internet after 3-4 minutes maximum. and then go restart again the router and again 3 min of internet...


Enable Adhoc on Jelly Bean [Is] there any way to enable adhoc mode in JellyBean. WPA_supplicant hack isn't working.

Root your phone, then use root explorer and download this wpa_supplicant file. Rename the original to wpa_supplicant_backup and set the permissions of the downloaded wpa_supplicant to match the permissions of the original one.

I tested on Android 2.3.6 Gingerbread it worked like a charm - almost. Sometimes I have to turn off the and turn on the WiFi twice but it's not a big deal.


HTC One M7 Keeps Restarting Itself I have recently bought a new HTC One M7.
Since the moment I turned it on it's performing random reboots. At the begining it was every few minutes but now its every time I unlock the screen.
I've performed 3 factory resets - didn't help (I think that even made it worse)
I've entered "safe mode" - still rebooting
I've tried to enter recovery mode but the phone got stuck on the loading screen (exclamation point icon)

Anyone might have an idea what's going on?
Is the phone defective? Might it be a hardware issue?

As I said, the phone is new, so no custom ROMs or strange apps installed

Thanks

At the end the problem was with the internal thermostat.
Had to replace the device.

Thanks for all the answers!

I had the same problem, still rebooting in safe mode. I found Amazon's software was using up approx. 55% of the CPU, and was kicking my computer off of the internet. Disabled Amazon, uninstalled all updates, and disabled automatic updates, and now phone is back to normal.


Can I flash a separate radio image and have a working radio? I have a rooted LGE Nexus 4. Installed on it are the Team Win Recovery Project and CyanogenMod 13 (Android 6).

I found this guide to installing stock Android 6 onto a Nexus 4, and it provides pre-built system and boot images, alongside:

  ... an OLD radio (initial radio release for Mako), [and then] this ROM will support LTE :)

In the comments section of that post, a user added how to install the pre-built image:

  From command terminal:

fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash radio lte_modem.img (or normal_modem.img)
fastboot reboot-bootloader

My question boils down to, can I just flash the lte_modem.img alone and come out with a working phone with CM13?

If that isn't inherently answerable, then: if something goes wrong, can I flash normal_modem.img, or do I need a CM13-specific radio image? Where do I get that special radio.img?

(Previous) Nexus 4 owner reporting in.

People at XDA had long been using hybrid modems with custom ROMs like CM. It seems specific versions are needed for each major Android version (JB/KK/LP+), but there's a nifty app right here you can try out: LINK: Google Play.

Also, there's no special radio for CM13. No custom ROM team makes radio themselves. Just flash back to a stock radio if things go wrong.

It sound's fishy ... or its a Brand specific image partition.
I have only ever seen the radio information built into the boot.img ... Unless it's an MTK aka MediaTek device, Then it requires flashing with SP Flashtool aka Smart Phone Flash Tool ...

The SP Flashtool version usually wipes the radio with a complete firmware upgrade, This is why most tutorials specifically state to use DOWNLOAD MODE .. In Firmware upgrade mode it will completely delete all partitions, and reinstalls the selected images...

Usually firmware upgrade will destroy NV-RAM " radio files " and then you will need to use IMEI Serial writer or SN Write Station to re-flash the NVram back with stock IMEI and Serial numbers (Bluetooth adress, Wifi mac etc...)     Under the battery or on original box

If you can ring *#06# and it says IMEI = null, Then you need a radio, otherwise the radio is fine... Usually your IMEI gets stored in the same place as radio for security i imagine.

If you open INFO by calling *#*#4636#*#* aka *#*#INFO#*#*You should see Phone info as a section,
- Open Phone info
- Press menu for more options or scroll down
- Press the WCDMA + GSM or whatever yours is, And try to select LTE ... If nothing happens then it's usually a hardware issue or limitation ..

How can I play audio over an open phone conversation? I would like to be able to play an audio recording over an open phone conversation. I.e., while the phone is connected (an outgoing call) a prerecorded audio file is played over the open phone connection.  How can I do this?

No, the best that you would be able to accomplish is playing a sound through the speaker so the microphone can pick it up. There are no api's that can accomplish that.

If you have a phone or secondary device that you can play the audio file on and both devices have auxillary ports, simply buy a cheap aux cable, cut it open, and plug both wires in the other way, so the phone thinks that the other device is a microphone. This works better that simply playing it through a speaker because there is much more clarity and no background noise.


What are folders Gift, MBSTGO & MBSTPH? Moto G, Android 4.4.4

What are folders MBSTGO & MBSTPH?

Which app creates them? Can I safely delete them?

If they don't have anything in them, then it should be fine to delete because they'll just be auto generated again when the app needs it.

MBSTPH is folder for low level protected mode run and shut. Contents png test mark inmages. Don't delete!


Samsung Galaxy 5 Wi-fi stops working: "ar6000 driver fails to load" My Galaxy 5 has this problem for some months now: wifi stops working, I try to enable it and the phone says "Error" without any other further information. The only way to make it work again is rebooting the phone. I think this problem has been related here before.

But I managed to save the system log and got the following:

08/04/2011 23:01:50 [ERROR] WifiService(166) setWifiEnabledDialog: true
08/04/2011 23:01:50 [ERROR] WifiService(166) ****************setWifiEnabledDialog(), allowWifi****************true

08/04/2011 23:01:51 [INFORMATION] wlan_tool(11029) wifi unloading

I'm trying to understand what's going on here. What exactly is ar6000? Maybe the network interface? How can I get more information about the error itself?

I have already uninstalled almost any app that could change the wifi behavior, and the problem persists. Juice Defender is still installed, but the problem already existed before I first installed it.

I've seen a number of people report that the WLAN test dialer code will allow the driver to reload properly (example). I believe it's *#*#526#*#* on many Samsung phones, but this post indicates that it may also be *#*#528#*#* or *#*#232339#*#*. This may not work on all devices, since manufacturers tend to include/remove different dialer codes almost at a whim.

If you're unfamiliar with dialer codes, simply open your dial pad and enter the sequence as though you were attempting to dial the number *#*#526#*#*. Your phone should then jump to the WLAN test facility.

wifi driver issue, factory reset or firmware upgrade could help you.


S4 cant unlock my phone I have a galaxy s4. I had the screen locked with a pattern. My 1year old daughter got a hoed of my phone and after the 5 incorrect patterns it asked for the pin. I entered the pin incorrectly  5 times so it asked me to wait 30 secs before trying again. Now I have the bar that says type pin code but when I tap the bar to type it in the keyboard does not pop up as usual so how do get the keyboard to pop up to enter the pin. I have tried restarting the phone, by pressing restart and shutting down and powering back up the phone  and  taking out the battery.

What specific code is it asking for? Cell phone companies can give u your plu code to enter and unlock to restore phone. Or performing a master reset manually..keyboard won't pop up right?
