Corrupted Images on S4 on Android Lollipop 5.0.1
I am experiencing issues with my S4 and the images I am taking on it.
Over the past week nearly all the images that I have taken have been corrupted when I go into Gallery or Photos to look at them.
I have had images sent to my via WhatsApp that I can save that do not become corrupted.
I'm using a 32gb sd card and I'm on Lollipop 5.0.1.
Is this a botched software update or a failing SD card?

As reccomended by The Droid Guy for Galaxy S5. I can only assume the solution can be proposed for the S4.

Lollipop Update Corrupted Photos in Galaxy S5 Sport
Problem: Good morning, I am hoping you are able to help. Two days ago, Sprint did a lollipop update on my Samsung Galaxy S5 Sport. Since
  that time, about half of my pictures, are black, stating unsupported,
  or media not found. I am heartbroken, as many of the pics are of our
  new grandchild. I have tried everything to fix this, but to no avail.
  I do have backup on, but, they are not there either. When removing sd
  card, to put on computer, same issue remains. Please help. — Julie
Troubleshooting: It appears like the update, somehow, has reached your microSD card and corrupted its contents. If your computer can’t
  ready from the card either, then find some technicians in your area
  who knows how to extract photos or files from corrupted SD cards.
  There’s nothing much we can do about it because it’s more of a
  hardware issue than anything else.

Thanks, i'm doing a full format of the SD card just now through Windows and if that doesn't work then i'll just buy a new 64GB MicroSD card. It's frustrating that a software update is affecting hardware in this way.

Lollipop has various issues like this. It's just unfortunate yours corrupted your SD Card, hopefully you didn't lose anything personal.

It doesn't look like i've lost too much, just photos and videos taken over the past week or so. I do have a friend who has had his entire MicroSD fried with all data lost!

Always good to hear, highly unfortunate for your friend though! technology is tempermental like that, i think thats why we love it so much. If you need anything else or if more needs to be added to gain an accepted answer let me know.

After updating to 5.0, default E-Mail drains battery
Recently I've updated my Sony Z1 Compact to Lollipop and noticed that battery is drained much faster than it was in KitKat.
~50% of battery usage is by builtin E-Mail app, here are the stats:

I have two e-mail accounts with following settings:

Check frequency -- Every 10 mins
Days to sync -- 30 days

It also overconsumes traffic - it receives about 7-10 Mb per day even if I don't have new emails. E-Mail server is IMAP w/SSL, but not Exchange, and both accounts are pretty big (about 4-5k e-mails). Usually, I've disable Wi-Fi. BTW, firmware is not rooted.
Any ideas what it receiving so eagerly, and how to stop it doing that?

How to encrypt an external SD card natively?
There are several questions regarding the possibility to encrypt an external SD card on Android. None of them are satisfactory. They either point to a third party solution (e.g. BoxCryptor, Cryptonite, EDS, LUKS Manager) or refer to a ROM specific GUI-way to encrypt. So my question remains:
How to encrypt an external SD-card with built-in kernel features? There is support for dm-crypt and eCryptfs.

For further reading:

What is encryption?
Android + encryption on the G1 using cryptsetup and LUKS
How does Android filesystem encryption work?

EDIT:
Since Marshmallow it is now possible to encrypt an external sd-card nativley with aes-cbc-essiv:sha256 as an adoptable storage. Sadly, this makes the internal storage of an android device unusable. In the light of the recent changes introduced in Android 6.0 I want to ask my question again and rephrase it:
Is it possible to encrypt an external SD-card with aes-cbc-essiv:sha256 without using it as an adoptable storage?

For further reading:

Decrypting Android M adopted storage
Android 6 semi-adopted storage
How to decrypt Adopted Storage?
Corrupt SD card formatted as internal storage

There is an option in Android 4.2.2 or higher that you can encrypt your SD Card on: Settings > Security > Encrypt SD Card. You need a screen lock to encrypt it. Once you do that, it will be encrypted.

This is what I meant as I was speaking from a 'ROM specific GUI-way to encrypt'. This option is just available in certain ROMs.

Okay... But I will update it if I find another.

How to remove spy-ware and how to turn off GPS-Tracking?
Someone installed spy-ware and is also tracking my GPS.  I can tell because when I open navigator the location is not where I am. I have driven to the location and someone is sitting in their car.  This same person follows me around town. also when I call my daughter a third party answers phone also so I can't get through to my daughter.I have tried factory reset but the person is still in control of my GPS.  How do I get control back on my phone?

If you're sure about this, go to the police.  You can install an antivirus app from the Play Store to try to root out malware.

In addition to that, consider changing your phone if the issue is irreparable.

I mean this in the nicest possible way but do you have problems with paranoia....that is the most logical explanation for what you're reporting in my opinion. Otherwise what you're saying doesn't make much sense - why would someone targeting you alter your gps to show their location as your location... That would just lead you to them... Also if your gps just shows that incorrect location as your location then it doesn't seem to be tracking you. Please consider seeking help.

How to use a paired bluetooth device as Smart Lock trusted device?
I am interested in using my Nexus Player (or other bluetooth device) as a Smart Lock trusted device for my phone. My goal was to be able to unlock my device without needing my usual pin while sitting on the couch. It seems like my Nexus Player (which never moves from under my TV) is a good candidate for that.
When I navigate to Settings -> Security -> Smart Lock -> Trusted devices -> Bluetooth, I can see it listed, but not connected:

Trusted devices not connected   (Click image to enlarge)
The devices are paired (but not connected):

Paired bluetooth devices   (Click image to enlarge)
Is there any way to use these as Smart Lock trusted devices?

I think you need to have a device actively connected in order to select it on the Smart Lock menu. Have you given that a try?

@eldarerathis Yes, that is true but how do you actively connect them is the issue. I've three devices with Android 4.2, 4.4 and 5.0 version They are all paired to each other, in 100 cm range and bluetooth with discovery enabled, but I don't see anywhere written something as "connected". In lollipop contrast to 4.2 and 4.4, you can touch the paired device to connect but its not working either.  I've the similar issue as the questioner have here.

@Firelord That seems like a separate issue from the Smart Lock thing, really. Many paired devices connect automatically when in range (the receiver in my car does this, for example) but I don't know how all devices work. Typically with phones and other smart devices I'd have to manually "connect" them for some purpose, like transferring files or tethering, but they won't connect automatically otherwise. From the screenshot it's not clear that the devices are physically in range at the time it was taken; paired devices are always listed regardless of their range/status.

So maybe the real question is "how to connect these devices?". Should I just modify this question or close and create a new one?

I managed to "trick" it into connecting by sending a file from one device to another. Then it becomes available to add as a trusted device. So I think you need to be actively doing something with the intended device in order for it to be "connected"
Your car does this because your car expects to receive data from your phone. Maybe you can use bluetooth to control the device you want to connect to?

Samsung Galaxy Note 4, same thing. I also installed "Bluetooth Auto Connect", and enabled my token device to be the first. (Otherwise it tried to connect to all the devices in order.)

Yes the device needs to be connected.  Most devices simply need you to press the blue button (or whatever makes a blue light flash).  Then in the setup...Bluetooth screen make sure it is scanning for devices.  If necessary, turn Bluetooth off then back on to force a scan.
When it finds the device it will first show an address (not the name) and you can tap on it to start the pairing.
Then when you ask for it to be trusted it will prompt you for a security code.
For many devices the code is 0000 or 00000
Here is an article that discusses the issue in detail:
How to setup Trusted Devices on Android Lollipop to automatically unlock your phone or tablet

I followed the advice to send a file from my laptop to my phone via bluetooth, and yes, then SmartLock was able to connect to my laptop.

How can I set a static IPv6 address for a WiFi connection?
I am running CyanogenMod 12 (Android L) on a OnePlus One, and would like to set a specific wireless network to use a static IPv6 address. I see a menu option for doing this for the IPv4 address (as well as hostmask/gateway) but not for v6.
Currently the connection is getting an address using SLAAC, on the prefix I am using. It gets its routing advertisement from a machine running a tunnel client and radvd.
Is there a method for doing this that preferably does not require root, and needs to only be run once and applies for that specific connection?

I don't believe Android itself offers this, so it's not surprising that CM doesn't.

@MichaelHampton, would you know if there is a terminal-based process, or one that involves a third-party app?

Open a terminal in your android or connect to your smartphone from pc with "adb shell" command. Then type "ip a" command, just to know how your needed interface is called. For me it is "wlan0 ".
Now, type the following command
 # ip -6 addr add 2001::your:want:ed_s:tati:c_ad:dres/CIDR dev interface
For example,
# ip -6 addr add 2222::1234/64 dev wlan0
Now execute "ip a" again or go to settings advanced and ensure, that your wanted address was assigned.
As I can see, this method do not survive rebooting. For permanent configuration you need use another way.

I don't want a static dns server for v6, I would like to set the device's address to something static instead of using SLAAC.

That doesn't really help this question though--the answer should be applicable to the question being asked. Do you have an answer for how to set the device IPv6 address?

@glockstar You can add your last comment into your answer. That will be helpful both to OP as well as a future reader here.

Does that method you mention persist across reboots and wifi connection changes?

@hexafraction Being based on the interface MAC address, in most cases the SLAAC address is static enough. Do you have a use case where this won't work?

@Michael I had not noticed this; I was under the impression that my specific android rom included a feature for changing MAC addresses for the purposes of connecting to WiFi and for SLAAC, for privacy reasons, but I would need to recheck carefully.

@hexafraction I'm running CM12 and (1) my Wi-Fi MAC address isn't changing on its own, and (2) I've never seen an option anywhere to change it.

Ip tools no longer works since Android 13

CyanogenMod 12 - is there quick sound/vibrate switch
In CM 11 there was a switch to mute my phone or put it on vibrate. I can't seem to find it in CM12. There are only profiles, which are not what I would like to have. Is this something missing from Android 5.0 Lollipop and thus not present in CM12, or did CM "broke" something? Or am I blind and couldn't find it, but it's there?

Do you mean the option in Quick Notification Settings?

Yes, that is correct. I would like to be able to choose between normal (ringer + vibration), vibration only, silent (no sound + no vibration).

You are right, no quick switch from top of the screen.

Solution 1: long press Power button, you get the option to switch to vibrate
Solution 2: change volume with physicals buttons, tap on setup on the right side of the sound pane. You will find options to switch to vibrate or mute for a given time or definitively.

How to update Google Play Services without having a Google account?
I have installed an app which apparently requires a newer version of Google Play Services. How can I upgrade these services to a newer version without having a Google account?
This is on Android 4.4.2.

go to settings > google play services app > tap build version > an update button should appear > tap that

That will only work with a Google account.

Btw. it's sad that the answer regarding Evozi and malware is not visible anymore. IMHO even bad answers should remain visible so it's clear which ideas have been suggested already.

@oliver Good, valid point. +1

You will need to goto a 3rd party website that hosts Google apps and download the newest (for your device) version. The one I use is  http://gappsandroid.blogspot.com/ , you can download EVERY single Official Google app.

Thanks, that sounds very interesting! Follow-up question: do you know where this site gets the APKs? And how can we be sure they don't add any malware embedded to their files?  I'm somewhat suspicious about downloading programs from random internet pages :-)

I can research tomorrow for you, but I'm pretty sure everything is on the up and up. I've been using this site for awhile now and haven't had any issues at all. I'm really particular about this situation as well.

APKMirror.com from Android Police is a good one too. They get the APK's from the community but test them before posting. They should be pretty safe.

@oliver Well I didn't get any conclusive details on the website, but I've compared the the files to those released on the PlayStore and they are the same. I have also gotten some pre-released versions as well.

You could use OpenGApps.  I believe it is sanctioned by Google and allows you to easily select a version for your device architecture and Android version, customizing the package by which apps/services you want.
Once downloaded, you can flash the package via recovery.  It is also possible to extract the apps for a manual upgrade; see my answer here for details.

Obtaining root access
I have a LGMS500 (never again), I have used Link2SD and Advanced SD Card manager and have moved as many apps as I can to SD card and this was not many. Any other app I try to move to SD card I receive the following "Could not obtain root access" "Allow or Grant to superuser". OK, newbe here when it comes to android, how do I obtain root access? While understanding this term as a former programmer, I have absolutely no glimmer on how to do this with Android.

It is slightly different for every device, I'd recommend seeing if there are any threads specific to your device and how to root it  at forum.xda-developers.com be careful to follow all steps correctly to avoid bricking your device.

how do I obtain root access? -- This is clearly mentioned and is still unanswered in what you posted as an answer. I recommend to please look for a clear-cut solution and post it here. Otherwise, if you have a recommendation as a clue or a hint (XDA here), do post it as a comment and not as answer. Thanks. :-)

Sorry, I didn't have enough reputation to comment. But I'll get a direct link to an XDA thread on how to root this specific device.

Sure :) and please quote/edit the content of XDA thread(if you get it) here so that if that thread goes down for some reason in future, your answer will still be relevant to a reader.

For an older version (<=4.3) try towelroot ( towelroot.com ) press logo get an apk, it's safe to use, so don't worry if your browser tells you it's malicious.
If it fails, look for other method for your phone model. There are thousands of manuals for that already.

Same android OS version -- one has move to SD card button, the other doesn't
I have two phones. Both have android OS 4.1.2 installed. Though on one phone it has "Move to SD card" buttons (though some apps have it grayed out), on the other this button does not appear at all. I mounted SD cards on both phones. And the same app would have the button on one phone, not the other.
I have read pages saying android disallowed that at some point. But how come they have it on some apps, not on others?
I loaded Link2SD and use the "move to SD" button there. I got this warning msgs:
"Warning: App2SD is not supported by your device. Because your device has a primary external storage which is emulated from the internal storage. you can link the app in order to move its files to your SD card"
I have little idea what it means. this phone only has 1.24GB of internal storage and it quickly drains.
Two models are Huawei Vitria (which can move to SD card) and LG-LS720 (cannot move to SD card)

Some phones don't have (external) SD card at all, like Nexus devices, so it's meaningless to move to SD card. Some apps also cannot be moved explicitly to SD card: http://android.stackexchange.com/questions/27816/unable-to-move-few-apps-to-sd-card

@AndrewT. Yes, but I mounted SD cards on both phones. And the same app would have the button on one phone, not the other

Which phone models do you have? Can you access the SD card on both phones? This is weird, but I don't have much experience with devices having SD card slot.

@AndrewT. Huawei Vitria (which can move to SD card) and LG-LS720 (cannot move to SD card)

It seems it's LG's doing: there are many cases for LG LS720: http://android.stackexchange.com/questions/83020/move-apps-from-internal-to-sd-android-4-1-2-lge-optimus-f3, http://forums.androidcentral.com/lg-optimus-series/323022-optimus-f3-moving-apps-sd.html, http://androidforums.com/threads/moving-apps-to-sd-for-lg-optimus-f3.766839/. For the reason itself, I still don't know, but unless someone knows, it might be hard to get the answer if it's not from LG themselves.

@AndrewT. I added more info I just dug out -- can you take a look at the edited question?

is CPU virtualization needed to run Android Virtual Device?
My Dell Laptop has Intel® Core™2 Duo Processor T6400 (2M Cache, 2.00 GHz, 800 MHz FSB) CPU which has no virtualization support.
http://ark.intel.com/products/40479/Intel-Core2-Duo-Processor-T6400-2M-Cache-2_00-GHz-800-MHz-FSB
Above link says :
Intel® Virtualization Technology (VT-x) ‡ no
My basic hello world Android application using eclipse not able to open AVD.
I can not see device window opening.
is that CPU visualization problem ?
Thanks in advance

You can always try to use an ARM VM instead of an x86, because the error log you provided states that: x86 emulation currently requires hardware acceleration!. So try this and report back. Keep in mind that QEMU (used for ARM on x86) is very slow and eats CPU cycles like crazy.

While running AVD I got the error:
[2015-05-04 23:02:01 - TESTapplication] Launching a new emulator with Virtual Device 'TEST_5.1_5.1.1'
[2015-05-04 23:02:01 - Emulator] emulator: ERROR: x86 emulation currently requires hardware acceleration!
[2015-05-04 23:02:01 - Emulator] Please ensure Intel HAXM is properly installed and usable.
[2015-05-04 23:02:01 - Emulator] CPU acceleration status: HAX kernel module is not installed!

and I got the thread which talk about this error.
https://stackoverflow.com/questions/27720064/hax-kernel-module-is-not-installed
so Conclusion is my Intel Core to Duo T6400 CPU do not support hardware virtualization and will not be able to run AVD. I need to get new Laptop to get this CPU function and AVD running.

Please include this information in your question and not as an answer.

How to prevent Firefox from killing music?
I have this problem constantly when I try browsing the web while listening to music. It doesn't happen on every page, but probably somewhere around 80% of pages will cause my music to stop playing. This happens with both streaming music via the Pandora app, and when I'm playing mp3s from my SD card through the native music player app. Does anyone know of a setting, either in Firefox, one of the other apps, or universally in the Android settings, that can stop this from happening?
This is an LG Optimus F3Q running 4.1.2.

I doubt there is. What you're experiencing most likely is a OOM issue (low memory, so the system is freeing some for the foreground process). You didn't mention anything about your hardware and Android version, so what I wrote is a "shot in the dark" – but I wouldn't wonder if the bullet hit at the right point …

@Izzy That could be. I've added the phone and version info.

Just added the link to the specs. Hm, 1GB RAM should be sufficient. Not sure how much of that Firefox eats, though – thinking of what it does on my desktop PC, I don't trust it to be really "economical". So additional useful details would include: how many tabs are open, what else is running, have you checked memory consumption (e.g. using an app like OS Monitor)?

@Izzy You might be onto something. This problem started to occur even between just the Pandora and Twitter apps, where I seemingly couldn't run both at the same time. I restarted my phone, started Pandora, then went into Twitter and clicked a link, which opened it in Firefox, and Pandora did not stop. I'll have to pay more attention from now on to see if memory really is the issue.

Agreed. And then don't forget to answer your own question once solved/proven :)

Select file from Downloads to upload via web form
I'm on a Samsung Galaxy S3 and want to upload a file from my Downloads folder to a website using a form on that web page.
But when I click the button to browse for a file to upload, I can only select files from my Music and Gallery folders, or the camera.
I tried putting the files in my Gallery or Music, but those apps only display music or image files.
So how can I browse to my Downloads folder and select a file from there to upload?
I can't quite believe I'm having such an idiotic problem.

What version of Android are you on?

You might wish to try installing a file manager. Those often "chime in" when an "select a file" action is invoked by the user, so you then could chose the file-manager when asked for an app to "perform this action with" – and then of course give you the freedom to select any file, not only "gallery items".

IMEI spoofing won't fix invalid Sim Card
I recently bought a second-hand LG Pro Lite. I restored it to its factory settings. For a few days, it worked properly. A week or so later, I had no phone service. Everything else works fine.
As I boot my device, the messages displayed are as follow (one changes into the next):

Service Disabled
No Service
Invalid SIM Card

I have tested the SIM card in another device and it works fine. I have tested other SIM cards in my device, none work.
My best guess is that the previous owner (which can no longer be found) reported it as Stolen and provided its IMEI No., thus rendering the device useless with the carrier. (?)
I want to make the best out of a bad situation, so I rooted my device and changed my IMEI using XPOSED Framework, rebooted it and... nothing. It was properly changed, but still no service. Is there anything else I can try to use it fully?
-
System Info:
Android: 4.4.2
Kernel Version: 3.4.67
Phone: LG D680 "Pro Lite"

What about talking to the person you bought the phone from?

As I point out, the person can no longer be found. Thus, I want to solve this through technical means.

I don't think that IMEI spoofing is the answer now, since the phone has already been blocked by the carrier. You would likely have to have it unblocked by the carrier.

AnkiDroid doesn't detect apkg file in the requested location
I have Android 4.1.1 and my AnkiDroid version is 2.3.2. I have downloaded a deck (.apkg file) and I would like to import it into AnkiDroid, which requires me to place the file into a specified folder /storage/sdcard0/AnkiDroid.
Oddly enough, the AnkiDroid folder didn't yet exist, so I went on and created it, paying attention to the proper 'CamelCase' in the name of the folder. I have copied the .apkg to this folder but I cannot import it because AnkiDroid cannot find the .apkg in that folder.
What is the problem? How to fix it?

You shouldn't have had to make that folder, it's not possible for it to not exist if you can use AnkiDroid. What value do you see under settings>AnkiDroid>Collection path? There should be a file called collection.anki2 in the AnkiDroid folder.

Strange, it should be seen in the Import dialog. Please fill a bug report at https://github.com/ankidroid/Anki-Android/issues thanks!
Meanwhile, you can use the second method for importing a .apk file:
https://ankidroid.org/docs/manual.html#_open_the_file_using_android
Just install any file explorer (like File Manager), and tap your .apkg file. It will open in AnkiDroid.

Hello i had the same problem before but now i know how to fix it.
All you need to do is to locate 'ankidroid' folder in your file system, not in storage folder but outside of storage folder then just copy the .apkg files there. No need to make new folder or whatsoever.

Granting device admin previlage to email account

Is it safe to grant the previlage?
Can someone else erase my data or do anything to phone?

I don't think something as simple as an e-mail client should be granted those privileges. Are you sure you're using the official Gmail/Exchange apps?

@Arielle Yes I am using the official gmail app. Without those privileges the exchange account will not work. No problem in using google mail.

Samsung Galaxy S5 AT&T - Stop 5.0 Lollipop update mid-download
I received an alert for a software update the other day that I kept putting off until today. Unbeknownst to me when I started the download, it was Android 5.0 Lollipop. I've read around that it still has some issues that need to be worked out and I'd like to avoid updating until I see better reviews and updates as Kit-Kat is running beautifully.
Unfortunately, I can't find a way to stop the download. I've tried restarting my device, looking for an option to stop it, etc. The only thing I've found that works is disabling wi-fi which, while it works, isn't a permanent solution.
Is there a way to stop the download and not install Lollipop?

well let the update download. After downloading you have manually install it so don't install. This way you can prevent the lollipop update and stay on kitkat.

Access Bootloader on VSD241
I'm trying to access the Bootloader on a Viewsonic VSD241, but the menu that comes up tells me to hit the "volume up" button to select Bootloader from the menu. There are no hard volume control options on this tablet, so I was wondering if anyone had an idea for what to do. Any help is greatly appreciated.

As an alternative route, have you tried using ADB in your PC? adb reboot bootloader command can boot you straight into your device's bootloader.

I did try that. The tablet shuts down, but won't come back up until I hit the power button. When it does, I still end up at the menu that asks me to hit the volume button.

This model has regular usb ports. Perhaps plugging in a USB multimedia keyboard would work to control the volume buttons. This page suggests that multimedia keys on a PC keyboard are equivalent to the volume buttons.

Bootloader frozen on Nexus 10
My Nexus 10s bootloader is stuck, it keeps saying "Downloading... Do not turn off target!!" and fastboot commands have no affect on it. I also can't use the volume rocker to boot into recovery or reboot the bootloader. If I try to boot it shows the Google logo and then the android boot-animation, which continues on indefinetly.
When this happend I was trying to flash the new system image onto it. I had already unlocked the bootloader without problems, but it may have been accidentaly disconected while running the flash-all script.
Can I restet my bootloader or flash android in a different way?

You need to hold Power until it shutsdown, then you need to hold Power and Volume - and + until you see the fastboot screen

how do I get my google play store to start working for my Samsung galaxy exhibit (T559)?
I was going through my app settings and accidentally uninstalled all my updates on my Google play store, it lets me pull up the old version but it will close out and say it has stopped working . I have tried to fix it but it won't work.

You can download the apk version from this link:
Google Play store 5.5.12
And install it after you downloaded it.
You might change the security settings of your phone to download apps from other sources.

"You must be a primary user to find this device" on Android Device Manager
Whenever I try to locate my new phone in the Android Device Manager, the following text is showed up:

Thing is, I am logged in as the primary Google account that my device uses. I also have the remote options in Google Settings > Security set to On, and the "Android Device Manager" checked in Settings > Security > Select Admins.
I don't really know what's going on, I've tried everything. Can someone help me? My phone is a Moto G2 XT1069, retail version.

Perhaps it's a different issue, but if you're using Lollipop, try deactivating the Guest account.

I hadn't seen your answer, sorry. It was a different issue, but it was solved exactly the same way as the link you've posted. Thank you!

Android Device Manager won't locate the device if it's currently not logged-in as the primary user. This applies to devices which support multi-user, including the default guest account on Android Lollipop.
Change the current user to your Google account on your device and try again.
In case it's still occurring on Android Lollipop, then try removing the guest account (refer to this question) and try again. It might be a bug related to guest mode.

Reference: Artem S. Lebedev's troubleshooting on Android Device Manager shows "No Active Devices" - Nexus 5 - Lollipop 5.1

Action: Switch to Guest Account in Lollipop interface.
  State: ADM says that you must be a primary user.

I had this message while trying to locate my phone from the web interface. I do the message "You must be a primary user to find this device." with a link to Googles Timeline Maps feature.
Once I found my phone, and using the link provided by Anderson Linhares I was able to fix it by clearing data for the Google Play Store and Google Play Services.
I rebooted and opened the Play Store to sync back up. I got full functionality from the web interface afterwards. In my case, the rest of the instructions don't seem necessary.

In case you have more than one google account on the same phone you should remove it.
for me and my Galaxy S8, the problem was having the Secure Folder enabled and inside it defined my Google Account too. I had to go to Secure Folder>Settings>Accounts and remove the Google Account.

Even though it wasn't the same problem, I solved this by following these steps:
Phone not appearing in Android Device Manager

It's good that you solved your problem, but could you at least mention what specific steps did you take? The link provides some suggestions, but not all suggestions seem to work, so providing the exact steps will help the future readers too.

Will I receive pending messages after I reactivate my account on new phone?
My Samsung Galaxy S3 was damaged by water and I now have a new Galaxy S4. I have reinstalled WhatsApp on the new phone. However I do know that I have messages sent by others that I have not received, they are pending.
Will I receive these messages? I have the same SIM card and there was a two week period between old and new phone.

"I have messages sent that I have not received", did you mean "I have messages sent by others that I have not received"? Otherwise, it doesn't make sense (you don't receive the message you sent)

@AndrewT. Yup looks like that's what is meant here(others sent him)

You will receive any messages that were sent  after the S3 died & activation of WhatsApp on your new phone.
However, any messages you had received on your old phone & didn't read cannot be received again.

No, you won't receive them, because there is no place to store them except of your phone. Since you haven't been registered, you won't receive these messages. That's my case when installing a new ROM to my phone.

Google Play Store: Error No. 905
I have Motorola Moto G XT1033, rooted. I installed CM12 Nightly. I am not able to download apps sized more than 200 MB from Play Store. No option to uninstall updates of Play Store.
How to fix it?

Get the latest play store apk from androidpolice and install it over the system apk. Check if it works.
Alternatively, you can also try uninstalling updates of google play services and check.

Running 16:9 games on a 4:3 screen device
I recently bought a tablet with a 4:3 screen. I noticed that some games don't seem to take this into account and the graphics end up stretched vertically. It can be rather distracting at times.
Is there a way to fix this, e.g. letterboxing to preserve the original aspect ratio?

One work-around is reporting the issues to the resp. devs, so they fix them up :)

GPS doesn't work offline on Samsung Galaxy S4
I have Samsung Galaxy S4. I am trying to get the GPS work on offline maps. I am for instance trying this on MAPS.ME app. If I have WiFi or 3G signal, the location works great. However if I turn on the airplane mode, and the location on, the application cannot find my location. I had the issue with Android 4.4 KitKat and recently upgraded to Android 5 Lollipop and the issue is still there.
I am pretty sure it is not an issue with the app because I also tried on Google Maps with a preloaded map and it is the same. I have also downloaded GPS apps such as GPS Test and GPS Status and they all manage to connect with satellites and find a location, even offline. I think that proves that it is not a hardware issue.
I think I might have unselected a Google option somewhere to block the GPS usage (I am usually very careful not to give Google too much data about me)
Any other ideas on fixing this issue?

How long are you waiting to get a GPS lock? GPS should work with Google Maps, for example, if you are outside in an open space with good visibility and wait several minutes.

If your GPS is set to use AGPS mode, it doesn't work at all when offline for some reason.
Go to Settings - General - Location - Mode - GPS only. I didn't notice at first that it was a selectable option.

on my phone, it is is exactely the opposite: I manage to get a location in google maps only if the location is set in "High Accuracy' (I guess in this case it is using the network to locate my phone.
... It seems that there is a hardware issue with the gpd of my phone!

App notifications block setting not set after phone restart
I updated my Sony Xperia Z1's Android to Lollipop (official update from Sony) a few days ago, and just noticed that the applications having their notifications blocked reset back when my phone is restarted. The Priority and Sensitive options are saved but the Block option appears to be not. For your information, the app I'm blocking is Psiphon – but testing this with other apps revealed it affects almost all of them, with a few exceptions only.
What could be the problem? Possible bug of Android?
Thanks

Okay, thanks for the info. Its hard to say if the way its behaving (since it happens to all apps) is either a bug or that's how it was designed to work. If you could perhaps read more about the update from Sony and learn more about the Notifications Manager. I am on 5.1.1 with CyanogenMod, and my notifications blocking etc are persistent.

I doubt Sony would do such a thing. Thanks any way, appreciate it.

@Rexford I just found out that some apps keep the blocked option. It seems that just **Psiphon** and some other apps doesn't.

This only started happening after the recent update so I would suggest this is a bug.

Need help re-rooting my Sprint Note 3 running CM12.1 Nightly 5.1.1
I installed a Nightly build of CM12.1 earlier today, but a few minutes ago when I tried to install an app that requires root access it said I wasn't rooted. For some reason I figured this was a given because I just flashed a custom ROM, but I am no Android developer (yet) and have no idea why it's not rooted. The ROMs that I installed prior to this didn't have this issue. Or it was spelled out in the install for me and I don't remember re-rooting them after I installed them. Either way, I need help with a method of rooting my Sprint Note 3 now and believe I need to use a specific tool or app to do so, and do not want to have to remove CM12.1 5.1.1 to do it (if at all possible). I also didn't want to run the wrong tool and screw up my phone because it was the wrong version of Odin (or whatever app I need to re-root). I'm pretty sure I have to use something specific to 5.1.1 but again, I'm no developer or heavy ROM flasher. If someone is a pro with Cyanogen ROMs I could really use some expert advice here. Thanks in advance!

Have you enabled root access for apps in the settings?

Yes, and it didn't help. When I open the 'Root Checker' app and click on 'check root status' the blue Android alien pops up on my screen and the Android reboots. Not the whole smartphone though, just the GUI.

Guess that's rather a bug in that nightly then. Never heard CM came without root – and I'm using CM for years. Especially that you have that option suggests it should be there. So I'd suggest either wait for an update, or use a previous nightly/stable instead.

Wouldn't the earlier nightly builds of this same ROM have the same problem? Isn't there an app I can run like Odin where I can flash a file to my phone that will enable root but not damage my current data and apps?

I cannot tell you whether an earlier or newer CM version has this issue or not – that's something to check with the CM forum. Not using a Samsung phone myself I neither can tell you about the Odin part, sorry. As I originally stated: it sounds like a bug in that CM nightly. So why not check where you downloaded the ROM, whether there are any reports or hints? Have you done that already?

Enable developer options and in developer options menu you will find an option

enable root access

If not download supersu zip file and flash it via recovery and you will get back root access.Flashing latest supersu willnot affect the data.So no need to worry about data loss at all.

I just got a live CM12.1 update that (I thought) completely fixed this issue, but it's still happening. The root works when I first flash it but for some reason it stops after a while and, even with the root option enabled in the developer settings. I read on a different forum that the SuperUser app is no longer needed for the latest versions of their ROM, and thought that it was what was screwing up my root, but I didn't install it after last flash and it's still not working.
Update: I thought that I resolved the issue but it's still happening. Is anyone else using on a Sprint Note 3 using CM12.1 5.1.1 nightly and experiencing the same issue? It's getting really frustrating. Whenever I try to do certain things, like try to run Root Checker or Greenify, CM12.1 soft reboots. I know it has something to do with the root-access but can't for the life of me fix the issue.

My friend..I had the same issue and I fixed it right away.. Here's the trick: download the supersu zip file(I have the beta), go to the developer settings and switch on Advance Reboot..Then go back to the home screen.. Press the power bottom..it should give you a pop-up window where you can choose to reboot into recovery: Choose It..then in recovery mode.. Install the supersu zip you were downloaded and then install it..Reboot your phone and check root checker. It should work.

You shouldn't need to download supersu, since root is available in CM already. It's in Developer Options > Root Access. Just change it to apps only.

is it possible to get app code from apk and customize it?
is it possible to get android socurce code from apk.
i had seen on some tutorial that shows the way to get code from apk just guessting if we can do it really .
please guide they way to do it if possible
i was able to get source code but issue is that when i try to run it in eclipse i see lots of error .

But you said that you have already seen the tutorial. Why then an explicit but unnecessary guide is needed? What's the issue with those tutorials you have seen?

@eldarerathis it's not duplicate check link it has not asnwer all links to answer is now expirer

This is called Android Reverse-Engineering.
There are a lot of tools out there that could decompile your apk or any apk in seconds.
An example is APK Studio which even comes with cross-platform support.
There are various IDEs for decompiling/editing & then recompiling of android application binaries.
There are even ones that completely are re-written using QT for cross-platform support. This will permit you to have multiple frameworks installed & to pick a particular one on a per project basis.
A one solution to prevent Android Reverse-Engineering is to just get patents for your code, and it will save you from a lot of trouble.

What about obfuscated code? Technically you can use the code, but you'd have to guess every class and method in order to get things to work. How do these decompilers handle de-obfuscation?

@EdwinLambregts  Obfuscation with android is very complex, because it has a lot of xml code, and with xml code it's not recommended, all for the part of variable references, so it's nearly impossible to achieve. Like proguard can let the xml part and all the related variables un-obfuscated, which in general they constitute more than 60% of the code would be out of the process and vulnerable thus it reflects on overall result which eventually will let go the thought of obfuscating for android hence from the beginning.

There are decompilers out there, but it's very likely that what you get out of it will be a garbled mess. If the developer used Android's ProGuard, you may not be able to reverse engineer the resulting code. The only site I know of for decompiling is this one.  Be careful and keep it legal.  Source code is intellectual property.  If the developer has a website or says their code is open source, contact them to find their github repo.

How to have Android use one ext3fs partition instead of going rogue with virtual partitions for apps on the external sd card?
As this answer pointed out, moving apps to your external sd card decreases your overall system performance due to the tens or hundreds of partitions created for those apps.  Now I wonder, is there any way to avoid this and have the system use a single partition, maybe formatted ext3 or xfs or the like? My devices are rooted, if that helps, but I'd prefer sticking to the stock (samsung galaxy) OS.

Playing on the tags you've used: have you checked our app2sd tag-wiki? Keep your eyes open there for e.g. Link2SD and Extended methods :)

@Izzy good point, sounds like I should try [tag:link2sd]

And if that works out the way expected, make sure to answer your own question and share your solution :)

Show only photos taken in camera app
In the Android 5 camera app, if you browse the photos taken, there appear also photos from Whatsapp, music album covers, etc.
Can you make the camera app only display photos taken?

Different OEMs  -> different camera apps. Which device are you talking about?

I never found any camera app with such behavior, but only a Gallery app. Are you certain its a camera app and not Gallery app?

Device is Sony Z1 compact.

I press the miniature image right of the shutter button, actually I don't know which app it starts, I guess it it's Gallery.

@Firelord some camera apps just do that for browsing: opening the gallery app :) And that's what's most likely happening here, from what OP describes in the last comment. // weberjn: you could try installing an alternative camera app (yes, QuickPic is a good choice). Next time you press that "miniature image" you should be asked what app to use. Some of those apps can be configured for "folder mode", which might work the way you want (not tested, just thinking aloud).

Will Titanium Backup Restore restore me to the groups i've been added in Whastapp
I have rooted my phone and I want to update my sony xperia v to android 5.0.2 lollipop with cm12 nightly rom. I have created a backup of of all apps+data using titanium backup.
My question is, will the titanium backup restore me the the groups i've been added in WhatsApp?

It will do more then just that, I use it every time I manually flash roms

Titanium will restore the app data.  If the app stores that data then yes it will, but that is something that is almost certainly stored server-side by WhatsApp.

Android apps won't connect over school WiFi
I have several apps that won't connect even though I connected to WiFi. Google Chrome and browser work fine, but other apps say can't connect to the server or needs an internet connection. When I'm at home, it works fine.

Most likely those apps want to connect to sites which are blocked by the school's firewall. Just a wild guess – but the most obvious possibility.

My school uses a similar system, probably the same actually.  What I think it is, is either Deep Packet Inspection or your Firewall.
I am almost positive, all I know is that your school blocks the applications somehow (it could also just block the website or server the app uses).

It really depends on which apps you are talking about.
Your school may be blocking certain ports. Check with the app dev to see which ports they use. This may be available through an FAQ on their site (which may include additional hints).
Your school may also have some type of content filtering solution in place. At my institution, our content filtering service is often blocking perfectly legitimate content.
Lastly, check with your school's network administrator. If it's appropriate content, they'll probably be willing to help open it up for you.

I'm in college and in my case, there is a proxy. This is common, and it's sometimes a good thing because it protects the people behind it. In this case, you may need to contact your network admin and ask how to access the network properly.
If the proxy has no authentication, it's just a little setup, but if not, you may need to use some app to get authenticated. If this is the case you can try ProxyDroid (it need root access) from here or PlayStore, or ProxyAuth from here on PlayStore.
Sorry if this is not the problem, but it was in my case.

Unable to install drivers of Nokia X on Windows 8.1
I have connected my Nokia X device with my PC which is running Windows 8.1. But in Device Manager it is showing as shown in below image:

When I Right click on it and select Update Driver Software and manually give the path of Android SDK where USB drivers are there, then it is showing below error (even though the driver files are available there):

Can anyone please help me what/where the problem can be?

The Android SDK does not have specific drivers for all devices; really on Nexus devices and those devices that use Google's vendor ID are directly supported (on Windows at least).
The drivers can be modified to work with different devices though; I found a version for the Nokia X here.
You could also manually modify them yourself by following this procedure (using the correct IDs for your device instead).

Sometimes win8 will refuse using drivers as they aren't signed for win8. Same problem occured on my machine when trying to install the drivers for xperia z2.
You can try this:
Press and hold "shift" and reboot win8, then choose "startup options" or similar entry in the menu, then choose reboot. Choose option 7 or F7 and reboot again.
Driver should install now.

Playing an embedded Youtube video directly in the Youtube app
I am using a very low speced smart-phone and heavy sites like Khan Academy are very difficult to load.
When ever I watch a video on their site my phone slow down and frequently crashes.
So, is there a way to directly play the embedded Youtube video in the app.
I want to do this because, that page could be locked away for a while, and I can concentrate on the lectures.
And can this be done without compromising the sites features, like the one that keeps track of "which and how much videos one has seen", so I could get my "energy points" and keep track of my performance. In other words, KA must know what videos I have watched.

Cerberus will survive a Factory Reset if it was installed as a system app via root.
But nothing will survive flashing unless it infected the bootloader, which is hard enough that you can treat it as entirely improbable.

Emoticon on keyboard support and Android version
I am wondering since what version Android emoticon have been added?

The answer depends on a variety of things, most importantly whether the vendor or manufacturer uses the Google keyboard or one of their own. Some apps, including Facebook and most manufacturer/vendor Messaging apps, have their own built-in emoticon support.
The default keyboard for Lollipop (5.0) on the AT&T Samsung Galaxy S5 has built-in emoticon support. If memory serves, Kitkat (4.4.2) did not.

According to caniemoji.com

Android 4.3 Jelly Bean was the first release to include a built-in keyboard (iWnn IME), and Android 4.4 KitKat is the first to include a color emoji keyboard.
Versions of Android prior to 4.3 require the use of a third-party keyboard app to insert emoji, or can copy/paste emoji from the list of all emoji.

Android 5.0 display keeps turning on with black and white notifications
I have an Oneplus One which just got its Android 5.0 version released.
It is known that there are still plenty of bugs issues, but a very annoying one is that if I have notifications and turn off the display, after a few seconds it turns on (only black and white) and off, on and off, a many annoying times.
If I turn my display off, I want it to be off, regardless of notifications I haven't seen/dismissed. I suppose it is consuming a lot of battery since the display is being on much more often than the usual.
I could not find anything regarding this issue on the Internet.
Anyone has seen it before/can help me?
Thanks in advance!

I once encountered similar behavior which was triggered by Ambient Display feature inside Settings. There is a guide on OnePlus Forums here (see Usage of Privacy Guard & Built in Settings (All Users)) which mentions this:

Ambient Display – this is again another option under the Display section of the Settings, when turned on (is ON by default) splashes notifications on the lock screen in black & white, every time you grab your phone off a table or something. This is a built in feature of Android Lollipop and is very useful. However, it is not that every time you grab the phone you wanna view notifications. You could be heading some where and want to keep the phone in your pocket or mounting the phone onto your car dashboard and the list goes on. So every time you do this, the ambient display comes and goes. While this may not eat up a whole lot of battery, turning this off will do something good.

Now that you know its under Settings →  Display & lights , you may try unchecking it and see if the issue ends. I had this issue when I flashed Lollipop and it ended right after unchecking it.

Thanks, that was indeed the issue! It seems it uses accelerometer data to infer whether the phone was grabbed or not, but it must be pretty inaccurate as I left it on the table and it would turn the display on and off a couple of times.

It also seems to do it when new notifications come in (and seems to cycle a couple of times before finally staying off). I've observed this on a CyanogenMod 12.1 nightly (based on Lollipop 5.1; 6/24 build for Sprint Galaxy S3) so I think it's an Android 5.x thing.
It'd be nice if they divorced the "turn on and off multiple times when you get a notification" option from the "wake up when you move your phone if you have notifications" option. I might actually like the latter. The former is flat-out annoying though when my phone is sitting on my desk in sight and keeps blinking.

@DoktorJ Thanks for the additional information. You can try filing your said opinion as a feature request here. You can see this as well to know a bit more about feature-request.

What are the ways to increase device Screen On Time?
I have a device with 2500 mAh battery and I usually get around 3hrs+ Screen On Time. Are there ways to gain some more juice...?
[I am a rooted user, so any method (root/non-root) are welcomed.]

The Screen On Time (SOT) depends on lots of factors like the way you use your phone, apps that you have installed, the strength of the mobile signal in your area, the data service that you have (2G, 3G, WiFi, LTE).
So it's hard to suggest anything specific.
What you can do is- use any battery statistics app (Like Better Battery Stats or Wakelock detector) and find out the apps/ services that are draining the battery. Then you can restrict these apps/ services based on your needs.

Greenify and Amplify Pro (didn't use but heard) apps as well.

I already use Greenify. Need other methods like scaling cpu frequency etc. for that matter..

For frequency scaling I use Synapse and its good, real good. I under-clocked my device's CPU to avoid constant overheating. I'm recently introduced to this and this app uses some UKM (I'm yet to learn).

Need to delete data from dead phone?
I have Samsung Galaxy phone. Now its dead. I tried lots of combinations and now I'm going to send it to India. In India it will get repaired but I don't want anybody to get the data, messages or media files which is in internal memory. But as its not charging, I can't delete data directly. How can I delete media files specially from internal phone memory from my dead phone?

What do you mean by dead...Not Charging Are you able to connect it to your System?

If you can charge a little  or arrange a new battry I guess you can do it by wiping data in recovery mode.

To do so hold the volume up, home button and power button simultaneously.
Once you are in Recovery Mode Scroll to wipe data/factory reset by pressing the Volume down button.

THATS IT.

Had a look around for you, I've never imagined it to be possible to retrieve data from a dead phone without external storage inside the phone i.e SD Card, then I stumbled across this article. A user commented something which i think you may find useful. I take no credit for this answer, try at your own peril.

WARNING! - Refurbished only means you will get a working phone back.
Even if they guarantee to return it with your data intact, be VERY
  CAREFUL! they are just telephone call handlers and do not know for
  sure what will happen, also people do not tick all the correct boxes
  and others do not look at all the boxes, so you could loose out those
  ways!
I am very surprised that there is no information on this subject.
It must have been an issue for 1000's of people over the past few
  years.
My problem is that "back up has stopped", would not re-install, and I
  could not find out why (it said memory, but there was loads free -
  since found it was talking about Dalvik).
Over the weeks I built up a collection of useful information and
  photos which I do not want to loose.
I am assuming yours is an Android phone, but even if it's a Windows
  phone, the principle is still probably the same.
It appears to be possible to recover files from the internal memory of
  a dead phone using a PC, free software and USB cable.
The principle is start the Flashing process, BUT do not Flash the
  phone, because I can not be sure it would not destroy your data /
  files.
When at the stage to be able to Flash the phone, effectively your PC
  thinks it is communicating have a "USB memory device".
This is achieved by removing the phones USB driver and substituting
  another driver (to enable the Flashing process).
I've not had the time to spend on it that I need.
I will come back when I do finish ...
BUT do not wait for me, there seems to be too many things going wrong,
  and the most important get done first. Which is why I have things
  waiting for over 1 year now.
One problem I have is that Windows keeps throwing out the
  "substitution USB driver" and replacing it with the original phone USB
  driver.
Windows thinks the phones driver is more suitable, so automatically
  re-installs it.
I know the issue, I've had it several times previously with the
  "unknown device USB driver" (a crash causes the driver change). I just
  need to find the "Windows stored back up driver", delete it, then
  Windows will happily accept the "substitution driver".
Ahhh, the joys of owning a MS Windows computer :-(
Some usefull software names :-
USB VCOM Driver
Windows drivers - A25_USB_VCOM_Drivers
usbdeview_droidtricks
Some useful search terms :-
brick
unbrick
flash rom
SP Flash Tool exe v3 (not to use, but the process' before is what's
  wanted).
Searches with search engines (Google, Yahoo, etc.), also You Tube (I
  could only find Flashing, but as previously, it's the process up to
  the "Flashing point" that you are interested in).
Sorry it's unfinished information, but at least it gives you hope and
  some where to start.
Data Recovery firms will be able to recovery the data / files and some
  are open to "please help, I'm skint ...", by reducing their prices to
  a poor private person, but they will not do it for free.
So good luck to all of us.

And this gentlemen in the comments of said post found a company willing to retrieve information from a dead phone, this could be worth a shot prior to sending it to India.

Hi Maria, sorry for the late response. They are called http://iekspert.dk/ or > iexpert.dk - try and write to them.

Just have a look and see what you find.

Change the default backup time of WhatsApp messages
The default backup time for WhatsApp is specific (in my case, it's 4:00 AM).
Although we can manually backup at any time, how do we change the default backup time?

What is more concerning, is that it is running at 02:00 UTC - meaning it does not account for local time and runs late evening or early morning.

It was backing up on 4am many years ago – a very nice time that few people will still messaging. But the automatic backup time has pushed forward to 3am and now 2am daily. A very inappropriate time to initiate a ten-minute long backup...

Sadly, it cannot be done. WhatsApp doesn't allow any other time to be set for the automatic backup of messages.

That's right, sadly, even though it seems plain stupid to me.

I am often carrying on an important conversation when 02:00 strikes and I go offline for 5 minutes, invariably with catastrophic social consequences!

To me, this is the most annoying thing on WhatsApp, I'm always using WhatsApp at 2:00.

It is stupid. Because at 2:00 my phone is on airplane mode while I am sleeping. Then the backup is pushed at when I wake up at 7/8 am

You cannot change the Whatsapp backup time to the local device storage. But optionally, you can have Google drive as your backup destination and can schedule it to backup as you wish (Monthly, Weekly, Daily or On click).
Google drive can backup your photos and videos along with the chat content in your Whatsapp account.

Yes but the backup is still done at the same time, so this doesn't help much.

Yeah backup is done as scheduled by whatsapp, its 2:00 in here.

Can KingRoot Brick my Nexus 9 and HTC One

If either is bricked, is there a way that it could possibly be recovered? If possible, could you please provide me with some statistics or percentages regarding the likeliness of one of these devices becoming bricked? Here are a few more specifications about my devices:
HTC One M8 Harman Kardon Edition from Sprint
HTC Google Nexus 9 (No carrier, WiFi)
Thank you in advance.

Ani

As usual, the answer is:  any attempt to modify O.S. files can brick your phone. But you can try to root your phones.  Just make sure you made a full backup of your phone software (not only /data), including boot.img and other sensitive parts of O.S.(system.img and so), and keep those files safe saved on your computer (so you can reflash your phone in case something goes wrong). Before attempt to root your device, the oem boot loader must be unlocked. The apk of KingRoot in itself does not produce to much harm on O.S. It just install a necessary su  binary to allow getting root access to system, and also some other files. The primary scope of any rooting tool is indeed, placing su somewhere in /system/bin and symlink it (maybe) in /sbin. If you don't know about flashing your device, don't ever try to do things you actually don't master.

Just make sure you made a full backup of your phone software -- but how? I mean without custom recovery, how do you make a full backup.

Firelord, I ussualy use SP Flash Tool for my MTK devices. I am sure there are tools to full backup your system images without root.

Firelord did you checked this http://android.stackexchange.com/questions/28296/full-backup-of-non-rooted-devices

Yes, I did check. Most of the answers revolves around using ADB for backup and adb cannot be used unless Android OS itself is working fine. Also, there is an exception for ADB but that requires custom recovery since stock recoveries doesn't provide such feature. Ultimately, it all comes back to how do you take full backup without custom recovery installed at all. ADB AFAIK  doesn't covers everything, just (system+user) apps+app-data+system-settings. This is what I saw by extracting backup.

SP Flash tool is way ahead in this since it doesn't require Android or recovery to be running while taking the backup. I used it to flash my devices but didn't know that it can take backup as well.

Firelord, I don't know if the tool works on other platforms, I used only for MTK. But this is the kind of software to be used. I remember using Odin for Samsung:) but those days are far away now.

Thanks user3344236! I don't plan to flash a custom ROM. Would my device still be bricked in this case?

Samsung S Duos GT-S7562
My galaxy s dous s7562 is getting switched off when Internet is on and sometimes is phone is also getting switched off even when the battery is around 50%. When the Phone is restarted the battery level shows 1%. I am not able to get connected with Wifi & Share it app with other phones.What is the problem. Please help me.

Might be your battery got corrupted or Expired, Have you tried replacing your battery, And do not post multiple questions within one.

It seems that your battery is older and needs replacement. Have you tried using apps like BetterBatteryStats? But they would just give you the stats and some more insights.
If possible try with some other battery.

Android studio - connect to device - Sony E2003
My old phone connected to Android studio but new phone doesn't. I've spent a couple of days searching forums and sites to try to help but whatever I try, studio just isn't recognising the device.
I've enabled debugging in developer options, but the device isn't being seen. I can transfer files from the device as normal, but when I click run (to run the app), there is no device available in 'Choose a running device'. Any help would be very much appreciated.
Thank you,

I was writing answer to your question in Stack Overflow :).

It might help if you'd name your device, Android version, and exact OS you're running on your computer. Also include whether you've installed the correct drivers for your device (when using some kind of Windows), or included the corresponding UDEV rules (Linux).

It seems your computer is not recognizing your device or not able to download the device driver of your mobile phone Sony E2003
Possible solution is to download and install moborobo from this website in your computer
http://www.moborobo.com/
It will install the required device driver to connect your phone with the computer and then your device can be easily detectable in Android Studio
Hope this will help!!!

Hi Ali, Moborobo doesn't recognise the device, but sony pc companion recognises the device and is transferring files, I can also transfer just by connecting via USB and opening the device files.

Actually for transferring files you don't need to have device drivers, For connecting your phone in Debugging mode you need to have the  device drivers are you able to sync your device with the PC using sony pc companion?

Moborobo will download and install the driver have you scanned the QR code? what error it has shown while installing the device driver?

Hi Ali, Thanks again for the response. Moborobo doesn't recognise there is a device connected at all. In connect device it tells me to connect device first, even though I'm already transferring files.

I managed to fix this myself, the developer settings were turning themselves off after I would enable. A reboot fixed the issue, for now.

Does CWM backup everything? Or just the actual system?
I have just created a backup using CWM. A 3.2G backup of a clean factory reset. Mental.
I am wondering that once I have installed all the apps, and make a new backup....that backup will contain EVERYTHING? Apps, photos, music...and so on?

I've just added the nandroid tag to your question – as that's what you're asking about. Please see its tag-wiki for more details – including the answer to your question :)

A backup created via recovery is a nandroid backup.
Yes, the nandroid backup created by any recovery (CWM, TWRP) will be exact replica of the phone state when the backup was taken- that means it'll have all the files/ data that you have on the phone.
Here is a good article about nandroid backups

Basically correct. Should be worth pointing out Nandroid creates complete disk images – so it basically "mirrors" all (relevant) partitions. It's not a file-based (logical) backup, but a "disk-based" one. So naturally, everything on the "disks" is backed up – not only the files, but also where exactly they were stored (not just in terms of directory-structure, but rawly, even which "sectors" they were occupying).

Can I generate the GPG key inside R2Mail2?
I just installed R2Mail2 and it seems to work fine so far, but I didn't understand the key generation procedure at the beginning.
What is this key for? Is this already a new GPG key-pair I can use? or is it just some internal stuff I don't have to care about?
How can I generate a GPG keypair inside R2Mail2? Or do I need APG to create my keys?

During the installation R2Mail2 generates a 2048bit RSA keypair which is used to internally encrypt data like stored key passwords or message content.
You cannot access or backup this keypair since it is generated during the installation.
R2Mail2 has no option to create a keypair for good reasons. For more information see my post https://groups.google.com/forum/#!topic/r2mail2-beta-test/RYYaj4tOrwc
regards
stefan

So the R2Mail2 developer doensn't want to implement a GPG key-generation in an unsecure device like Android for good reasons. Well then: if security isn't that important for you, you can use Openkeychain or APG still.

How to keep an app running?
I have installed a talking clock app (named "Tell Me The Time") that say the current time every quarter hour. However I does not stay active and I have reopen it occasionally. At the same time, another similar app does not have this issue and remain active in the background. How to keep an app active (running) in the background (24/7)?
The issue is also more serious in using Torrent clients (they actually are useless in android).

It depends on how the app has been developed. Generally, android service needs to be running if you want the application to remain active in the background. But, if services are not used, then as soon as the activity disappears or destroys, behaviour is no longer observed.

An alarm would be better, and less draining to the battery.

As I mentioned in my answer, 'service' is the key factor. An alarm can be set on by using trigger actions. But, if not embedded in service, it will not work as soon as the user leaves the activity, Better to focus on using 'services'. This will ensure that the app will work even in the background.

So do you mean that it's impossible to keep an app running?

By keeping screen On continuously might serve the purpose, but its not practically feasible (battery constraints).

To my knowledge, you cannot properly ensure that without being the developer of the application (and even then there is no guarantee).
You need to know that the Android system is geared towards killing applications in the background as the device runs out of memory. The general rule-of-thumb is, that inactive apps are killed in favor of currently active ones if memory is low. I am sure as a developer, you can circumvent this to an extend with workarounds like trying to keep your app running in the background and bring it to the front regularly, restart it at fixed intervals or something similar.
But as a user being given an arbitrary application,  this sounds almost impossible.

Change theme on Samsung Galaxy Alpha
I have a Samsung Galaxy Alpha G850A and while I've been able to adjust a lot of settings including the wallpaper for the home screen, lock screen, etc I haven't figured out how to get rid of the ugly Windows 8 4 bit color scheme. Other phones apparently have access to a theme option under settings, mine shows nothing when I search in the settings for 'color' or 'theme' and I've probably have gone through 95% of the various settings manually at this point.
How do I change the theme colors on my Samsung Galaxy Alpha?
I am completely willing to hook it up to my PC and manually edit configuration files if someone is that awesome to know where it is (and if it supports RGBA)?

Is that color scheme affecting all your apps, or your home screen only?

@Izzy Most of the programs are blue/teal (phone, contacts, calculator, etc).

That's not what I've asked, John. I meant whether that 4-bit color scheme is affecting all apps, or if it's only present in your homescreen/launcher. In the latter case, an alternative launcher might solve your issue.

Can you still connect the phone to a computer via USB and view the data stored on it?

It depends on what details you gave on your Google account. You have to had entered either a recovery email or you phone number and your real name. If you had these, you can try to recover your username from https://www.google.com/accounts/recovery/forgotusername and after that you can reset your password from https://www.google.com/accounts/recovery/ .

Volume down key not working. How to enter flashmode
I am using Sony Xperia Z1 Compact. After replacing its screen the Volume-down key stopped working.
However I am in Bulgaria and cannot wait anymore for the Lollipop update, that is why I followed this guide:
http://techbeasts.com/2015/04/14/update-sony-xperia-z1-compact-d5503-to-android-502-lollipop-145a0242-firmware/
However without Volume-down key I cannot finish Step №9: For Xperia Z1 Compact Volume Down key will do the job of back key, just turn off your phone, keep the Volume Down key pressed and plug in the data cable.
Is there a way to simulate pressing the volume-down or to install the "FTF Firmeware" without it?

Thanks!

You can use ADB to connect to your phone over a terminal and issue the following commands to reboot into Download Mode
su
reboot download

Your phone will need to be rooted to run the 'su' command.

AT&T Samsung Galaxy S6 will not connect to WiFi automatically
I have an Asus TM AC-1900 WiFi router at home. We have a Nexus 4, Nexus 5, Nexus 7, iPhone 6 Plus and notebook computers. They are all able to connect to Wifi when I get home. However, the new AT&T Samsung Galaxy S6 will randomly fail to connect to WiFi when I get home. It does manage to automatically connect some of the time but most of the time I have to remember to connect it manually. Is this a defect on my particular unit? I have tried doing a factory reset but it doesn't seem to help.

First off, when you go to wifi, tap on the "more" button on the top right, then tap on "smart network switch", and make sure it is turned off. Sometime it will detect that your wifi is unstable when connecting, so it won't connect. If that does not work, try tapping and holding on your network, then click forget, and reconnect to your network, but I have the S6 edge, and it auto connects to my wifi network all the time, so you might have gotten a defective one. Before you exchange it, I would test it out on another wifi network to see if it does that same thing. Let me know how this goes!

Also, are you sure you have the wifi on all the time? In wifi settings, tap on more, then advanced, then look for "Keep wifi on during sleep". I have mine set to always, so I don't have to keep turning wifi back on.

Thanks but after talking (after a log time being on hold and getting passed around) with AT&T, I exchanged the phone at a local store. Same problem again. AT&T placed a diagnostic app on the device but they didn't offer any more solutions. I've returned the phone and cancelled my plan. Still no idea why only the S6 should fail where literally nothing else does.
How do I close a question?

I’m voting to close this question because the OP cannot evaluate the answer anymore without having the device, and no existing answers have been upvoted for more than 5 years.

Was having issues with my s6 staying connected to open aps. Made sure the smart network switching was off, wiped cache and messed with other settings. Nothing worked.  I opened up the AT&T smart WiFi app and adjusted the settings for public hotspots. No problems since making the change.  I disabled the app no problems staying connected.

Open the “Settings” and go to “Wireless/Wi-Fi”.
Scroll down and at the end you’ll see the option “Smart network switch”.
Uncheck this option and you’re done. For more details you can refer Samsung India site.

How to root Sony Xperia C3 Dual D2502 running Android 5.0.2?
I use Sony Xperia C3 Dual D2502. I've installed Android  5.0.2 and now I can't root it.  I can't root it using Sony Flashtool method.

Model Number: D2502
Kernel Version: 3.4.0+
Build Number: 19.3.A.0.470

How can I root it?

What are the error messages if you try to root it your way?

No error messages but the phone doesn't start after using the method,  then I've to install the firmware again :(

To root you must follow this handy tips
1) Before getting started with the rooting procedure, take a complete backup of personal data in your smartphone using appropriate apps. If you don’t take backup and follow the procedure given below, then your personal data will be wiped out, and you can’t recover them at all.
2) Ensure that your device has a good battery backup or else charge it fully, before carrying out the procedure.
3) Download Sony Xperia USB drivers and install it in your computer, so that you can connect Xperia C3 with it.
4) Enable USB Debugging mode in your device by following the path: Settings -> Developer Options -> USB Debugging Mode (tick the box to enable it).
When done you can start rooting
1) To get started, you have to unlock the bootloader of your Xperia C3. To do that, visit this page and follow the instructions given there to get the Unlock CODE (which will be sent to your email address).
2) Next, download Flashtool and install in your computer. Once done, switch off your device and connect it to the computer while holding the volume down button until the phone LED turns into blue color.
3) Now, click BLU on the flash tool and follow the onscreen instructions. Once it is done, disconnect your Xperia C3 from the computer and reconnect it to the computer while holding the Volume up button until you see the Flashtool asking for the Unlock code (Step 1). Just enter it and your device bootloader will be unlocked.
4) Next, download CWM and SuperSU, extract and save them to your computer. Once done, connect your Xperia C3 to the computer while holding the Volume DOWN button until you Blue color in the LED.
5) Now, open flash tool and select Fastboot mode. Next choose “Kernel To Flash” followed by “*.img” and finally choose the boot.img that you have got after extracting the CWM recovery (Step 4). The flashing process will begin and within few seconds will get completed. Once done, disconnect your Xperia C3 from the computer.
6) Next, switch on your device, connect it to the computer using USB debugging mode and transfer the SuperSU.zip file (Step 4) to the SD card. Once done, disconnect your device again.
7) Now, switch off your smartphone again. We have to boot into the recovery mode for flashing SuperSU. To do that, switch on your device while holding the Volume UP button until you boot into the recovery mode.
8) In CWM recovery, select “Install Zip from SD card”, choose the SuperSU file that you have transferred to the SD (Step 6) and start the flashing process. Once it is done, Reboot your device normally.
You can find the contents here: http://www.androidrootguide.com/list-android-custom-roms-official-roms-root-software-download-links from CWM to the rom
That is one way the other way to root your phone is to get UnlockRootPro. You connect your device and then select it from the dropdown menu and click root. But remember to do the handy tips on the first link.

Link only answer does not help if the link becomes dead later, and for the other way to root could you share the link for the app, steps to perform?

Is there a protocol for android which allows direct file modifications from computer?
Both the MTP and PTP protocols for file transfer do not allow editing or viewing files on  the phone from computer directly. In other words, you have first copy the file from the phone on the computer and then view/edit it. Are there any alternate protocol that support viewing/editing files directly?

kitkat usb connection problem
my galaxy grand 2 cannot connect the sd card of usb storage to computer. only 2 options are available with usb
namely
media device
camera
how can I access the files of sd card and usb storage
Please note that Im using Ubuntu 14.04
I have no problems with windows

Ubuntu 14.04 seems to have some issues with MTP working correctly. You need to install the mtpfs and make sure the phone usb connection is set to MTP to work.
See the Ubunto syack exchange for more info. https://askubuntu.com/questions/463015/ubuntu-14-04-and-android-cant-see-phone-on-my-computer

In synaptic I searched MTP. It listed programs and libraries related libraries. From those I installed Qlux, mtpfs and some other libraries (I coudnt give the exact details for now since Im away from home & codnt have my laptop). After installation connected my phone and opened Qlix. It searched for MTP devices and found my phone(both card and phone dtorage). Try this. Best of luck

Thank you for your valuable information. Sorry to say but it didnt work. Then I installed Qlix and some other libraries for MTP. Now its ok. I can connect the phone memory and sd card to Ubuntu 14.04 and can transfer files from and to the PC.

Since its about Ubuntu 14.04 which is the recent LTS release from Canonical, could you mention the names of the libraries (version no. will be too good) and the steps that you followed to download and install them? That would make it a completely useful answer with everything(except libraries) available here.

How to host Wordpress site on Android device
I am trying to host a Wordpress site on my old Android phone, but so far I have been unsuccessfull...
I tried with KSWEB and Ulti Server, extracted the Wordpress.zip in the sdcard, and when I try to connect to the server I am getting error with the database...
Error establishing a database connection

Does it also has to run some other SQL server on the phone for everything to work?
I really don't know what am I doing, and there aren't any good explanations on the internet, so please help me

Wordpress requires a database to run.
After installing KSWeb, you will need to create a database for Wordpress.  To do this:

Open KSWeb.
Go to Tools → select phpMyAdmin (it will install).
Open Chrome browser.
Go to localhost:8000 (to connect to phpMyAdmin).
Select the Databases tab.
In the box below the label Create Database enter wordpress, select create. Your wordpress database should now be created.

Now wordpress needs to be setup.

Move your wordpress folder (unzipped) to /mnt/sdcard/htdocs/.
Open a browser and go to localhost:8080/wordpress. It will ask you to setup your database connection.
Enter root for the username and clear out the password field (you can leave everything on the default settings).
Select Submit.

It should now connect WP to your database.
Thought about using a Raspberry Pi?  I've setup several Wordpress Sites on the Pi (with MySQL) and you can set it up with your network for local website hosting.
References:
Wordpress - Do I need a database

so can I host some other website, made with different platform? I want it to be on my phone

or how can I run a database server along with the other server?

See the modified answer on setting up everything

I've gotten way further than before, it's all good now, but I can't seem to be able to access the Wordpress server from external IP, I have configured my router to forward the 8080 port, but now I can't connect to the KSWEB server (I was able to connect externally to a server made with Ulti Server, but this one is giving me problems...). Any help?

Can you access your WP server on the same network (the LAN) that your phone is on (e.g. 192.168.1.8:8080 on your broswer from a different device)?  Are you specifying the port when connecting from outside?  Are you connecting from a different public IP than your phone is on? There will be issues if connecting from the same network.  What is the error msg that you are getting?

Yes, I can connect to the Wordpress site from another phone connected to the same Wi-Fi. But if I try from my computer, using the external address of the KSWEB server, like this 78.83..:8080 (with, or without /wordpress at the end) it simply doesnt load.

If your computer is on a different public IP than your phone, it sounds like a routing issue.  If your computer shares the same public IP address, you will not be able to connect.  Try using a proxy if that's the case public proxy

no, its something to do with the KSWEB server, I even tried with my phone on celular data, and still can't access it... and I know its KSWEB because I can access a server created with Ulti Server, from my computer

I did it, all I had to do on the router was forward the ports like this: 8000 > 8000 instead ot 8000 > 80 and so on

5.1 update downloaded to my Nexus 7, incorrect version number
I got a notification today on my Nexus 7 (2013 version) that an Android update has been downloaded.
It's currently running Android 5.1, build LMY470.
The update screen says:

This software will upgrade your Nexus 7 to Android 5.1
  ...
  Update size: 18.0 MB

I read an article indicating that the 5.1.1 update is coming out soon. Is the downloaded update really for 5.1.1, and the "5.1" in the notification is just an error, or is something else going on?
This article says that the 5.1.1 update is 18MB, which is consistent with what I have.
UPDATE 2015-07-08:
Something very similar has happened again. My Nexus 7 (the same one) is currently running Android 5.1.1, build LMY47V. I've received a notification for an update to Android 5.1.1, the same version. The update size is 18.0 MB. I applied the update; it now says it's running Android 5.1.1 build LMY48G. A Google search for "LMY48G" gets a number of hits, but few if any details about what's in it.

After a couple of days, I decided to go ahead and apply the update. It completed normally and the tablet is now running Android 5.1.1, build LMY47V, which is what's expected for the 5.1.1 update.
It looks like the only problem was that the version number was displayed incorrectly. I'm still curious about why that happened, and why I haven't been able to find any other reports of the same problem.
UPDATE 2015-05-26: I've received the update on my Nexus 4; it correctly shows the version number as 5.1.1. The update size is 18.1 MB.

I had this same issue and I also believe this is a problem with the version number.

@LJD200: A quick Google search doesn't show anything definitive about a post-5.1.1 update, but my guess is that this may be 5.2.

@LJD200: Looks like my guess was wrong; it's 5.1.1 build number LMY48G.

OK - this makes sense. 5.2 definitely hasn't been released

Cannot read Android Partition Image created using ADB
I am currently working on a Mobile Forensics demonstration for my college's computer science capstone. For this demonstration I have been trying to create a partition image of the an old Droid x2 user partition and then examine the resulting data using forensic software. However neither FTK imager, nor Autopsy have been able to read the created image files.
I have been working with a rooted Droid x2 running 2.3.5, and have been using Android ADB to try and create a dd image.
  'adb shell dd if=/dev/block/mmcblk0p16 > userdata.dd'

This command seems to work and creates an appropriate sized image file but various forensic software give errors such as 'does not contain valid evidence.'
I have tried creating .bin, and .img files to similar effects.

Turn off WiFi only when the device is both locked and screen turned off
I have already tested some apps for this purpose and they solely rely on the screen turning off, which makes sense at some point. However, their concept breaks down when you want to use an app over WiFi which has the capability to turn-off the screen due to the proximity sensor (think of the VoIP apps). Turning off the screen in that case means disconnection from the network.
Is it possible to turn off the WiFi only if the device is both locked and screen turned off?

If I understand your question correctly, then there is a very easy way of doing this yourself. Im sure there are many ways of going about this, but this is the easiest and most reliable method that I know of.
You said that you wanted something that doesn't rely on the screen being off. My solution does rely on the "display" being off, however for the "display" as opposed to the "screen" to be off, the device must be locked, meaning that this should work flawlessly for you.
If you just follow the instructions I've provided below, you should have satisfying results in just a few minutes!

Download Tasker from the Play Store.
Open Tasker and click the + button. Now click Event → Display → Display Off.
Click the gear (back button) in the top left corner. A pop up menu will appear. Select New Task and name it Display Off.
Tap + → Net → WiFi and make sure the box that says Set is set to Off.
Click the gear (back) twice so that you end up on the Profiles screen.
Now click + again, then Event → Display → Display On.
Tap the gear (back) and then select New Task. Name it something along the lines of Display On.
Click + → Net → WiFi and change Set to On. Now exit back to the Profiles tab. You should now have both Display Off and Display On.
In the Profiles tab to the right of your conditions, there are On/ Off toggles. Turn both of these to Off and then back to On.
Simply exit out of Tasker and you're done!

Good luck and I hope this helps you!

how will this behave in case that I use an app which turns the display off due to proximity sensor? Will it turn off the wifi radio then as well?

@KristofPal it should turn off the wifi radio with the app your talking about.

Do you need root for this?

If I understand the question correctly...
There is a setting under WiFi -> More -> Keep WiFi on during sleep

click image for larger version

forgot to mention I tried that... still able to ping the phone when locked... wierd

This is probably because with all apps running, the phone never enters sleep mode, so the setting is pretty much useless.

Knox official warranty statement from Samsung
I have a Samsung Galaxy Note 3 (N9005), and it has a problem with GPS. It's definitely a hardware problem, as I changed the software and did everything, software-wise, to fix it, but no use.
I would like to send it for repair, but my knox bit is 0x1. I searched A LOT... on how to reset that, and I couldn't find a clear answer. (if you know one that's working, I'd appreciate that).
My question is: What is Samsung's statement on knox warranty? Is it that I lose warranty on everything if my knox bit is 0x1 or just to software issues? Many people have said many different things and I'm confused! I couldn't find any official source from Samsung explaining this... could you help me find one?
Thanks.

Your warranty is void. But try this:
http://forum.xda-developers.com/showthread.php?t=2740340
 Its a howto for resetting knox.

I'd appreciate it if you could tell me the source of the information that "my warranty is void". This is the core of the question! I never saw anything official from Samsung stating that 0x1=warranty void.

Thats what the text in Odinmode says KNOX WARRANTY VOID

Thanks. But it's not clear what kind of warranty they mean. Warranty is split into multiple parts in their website. For example, batterie warranty is for only 6 months...

I have to say that I sent my phone for repair, and the repair people never mentioned a problem with warranty even though knox was 0x1.

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.

I don't know whether this will hide your accounts from gmail but you can turn syncing off for gmail and calendar for accounts you don't want to sync..!
You can change the account sync settings from within settings-> Google then choose the account you want change sync settings of.

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.

Hi, this a friendly poke since I'm honestly confused why this post looks a bit unreadable compared to all your other posts. Would you [edit] this post to improve it? Thanks.
