Unlock Screen with ADB Android 4.1.2
I have a Sprint Galaxy S3 (v4.1.2?) that I've rooted with CWM. Last week the glass and display cracked, so now I can't access it directly.
I'm able to access it with adb so would like to use something like droid@screen or androidscreencast to access it.
The problem I'm having is with the screen display lock. It's set to press-then-tilt-forward to unlock the screen but I can't figure out how to send those events using adb to do it successfully.
Why doesn't droid@screen or androidscreencast do that directly anyway?
I've tried sending various keyevents including 82,83,1,3, among others, and none seem to have any effect. What is the proper keycode to send to disable the screen lock?
Thanks,
Alex

You could check whether there's a way to disable Keyguard (there must be some intent to use, as many apps like e.g. Tasker support that). That would turn any keylock off. One example how to do that I just found at Google Groups. First, that thread says the keycode should be 59 (keycode.KEYCODE_SHIFT_LEFT), but then also offers alternatives like:
$ adb shell
# cd /data/data/com.android.providers.settings/databases
# sqlite3 settings.db
sqlite> update system set value="-1" where name="screen_off_timeout";
sqlite> .quit
$

Heavy hack :) I'd recomment to check the value beforehand, so you can use the same way to revert things back (i.e. lock the screen again). Also, that rather looks like it would only disable the screen timeout (but not actually disable the lock if the screen is already locked). As a similar trick is used in Cannot unlock tablet as have no internet connection?, that might serve as an alternative:
> adb -d shell
# sqlite3 data/data/com.android.providers.settings/databases/settings.db
sqlite> update system set value=0 where name='lock_pattern_autolock';
sqlite> .exit
# exit

But this one only applies if you use pattern lock.
As written above, there should also be a way to do that via some intent, but I could not find a clue on which one that might be.

Can we install the stock ROM for P3110 on P3113? (7 inch Galaxy Tab 2)
The P3113 model of the Galaxy Tab 2 hasn't yet received the Android 4.1 (Jelly Bean) update.
Is it possible to install the stock ROM for the P3110 ROM (take from sammobile) on the P3113 device?

What's the difference in the two models? I would assume they are most likely not compatible. For example, Samsung Galaxy Nexus exists on different carriers, each is a different model and they are definitely not compatible with each other due to hardware differences for carriers (mainly CDMA vs GSM)

Another example would be the Wifi Xoom vs the 3G Xoom. Not compatible.

Agree with Bryan but I can't find much by Googling.  Comments seem to indicate it might work but nothing conclusive.

@BryanDenny - The p3113 is basically the p3110 (Tab 2 7.0 wifi-only) with a IR transmitter tacked on.  They're otherwise identical.  CyanogenMod considers them to be the same device.  The p3100 is the different one, which is the 3G version of the Tab 2 7.0.

As a fellow Tab 2 user, I can quite happily tell you that any ROM for the GT-P3110, GT-P3113, or GT-P311X (Where X means 1 or 3) will work with essentially no issues, except you MIGHT lose IR capability. Other than that, Hunky-Dory!

You can install it, but not everything will work properly. Most things should work, but not all.
Read the forum / thread from where you are downloading the ROM. If you are okay with a few things not working you can get it. Otherwise, you might want to wait till a ROM is ported out for your particular device.
You can read the XDA Forum thread What's the difference between 3110 and 3113? to know what people have got working and what didn't work for them.

I have lost All my contact on Samsung Galaxy S GT I9000
Yesterday I have lost all the contacts on my GT-I9000. The device was left alone for 5 minutes & when I checked it again for some work, I found that the contact numbers had been lost & I am not able to find them.
Is this a common problem with GT-I9000? Is there any way to get the contacts back?

Weird, this happened to a friend of mine too, just yesterday...

I don't know how you lost them or if its a common problem. But you definitely can get back the lost contacts provided they were synced with Google Contacts(not SIM contacts).
First try to sync and see if contacts come back. If we cleared data of "Contact Storage" from Manage Applications, all the synced contacts in phone will disappear until you sync back again.
If that doesn't help, Google Contacts fortunately has restore option. Open Gmail, go to Contacts, Select More and select Restore contacts.

I also lost the contacts yesterday on a Samsung Galaxy S, because I thought they were synced to Google (the sync setting was active, and showed it was done) and re-installed the OS (hoping to get the contacts back from Google). But it turned out they had not been saved on Google (although no errors were reported). Perhaps, this is similar to the sync to Picasa problem which is reported to happen when you have also connected to your Facebook etc. accounts, no?

Do I still need to install GAPPS if I want to use the new Cyanogenmod Android 5.0 rom?
I was just about to flash the latest the build for Cyanogenmod, but then I remembered from past phones where I flashed new ROMs, that I needed to install the latest Google Apps file. However, when I went to see if I can download the latest I see that there is not a full build for it (unless I read it wrong).
Do I need still need to install GAPPS if I want to use the new Cyanogenmod Android 5.0 ROM?
Since the build is not complete for GAPPS should I wait?
GAPPS forum on XDA

You don't need to install Gapps to use Cyanogenmod, you can install it and use it without them.
If your real question is "do I need to install Gapps if I want to comfortable install all my favorite apps from the playstore?" then the answer is probably yes.

So ideally I do need GAPPS. Because if not then I have no apps.

If you want to install them the confortable way, yes.

Great thank you for the clarification. Looks like I'll be waiting.

You don't need to wait - there are several 5.0 GApps builds out there and the ones you linked to will work to get you Play Store and Play Services. The other GApps builds have other Google apps (Gmail, Hangouts, G+, etc) which you don't need and can usually install from the play store...

To cut a long story short, GAPPS basically provides you with the sync between your device and google services, which otherwise wont be readily available on custom rom running devices.

Android stuck on roaming mode
I own a Samsung Galaxy Note 3 (SM-N900), with Android 4.4.2 installed on it.
It was purchased through Partner (Israel) and I have recently moved to Germany for work.
Upon my arrival, I purchased a SIM card from a carrier called Lycamobile and I regularly top up my account per demand.
Problem - the device is stuck on roaming mode.
What I've done so far:

I toggled Data Roaming in the More Networks -->Mobile Networks menu; when enabled, the device is set on Roaming Mode automatically (see figure #1).

When Data Roaming is disabled, mobile data is disabled, too (see figure #2).

Taking the SIM card in and out several times hasn't helped much (I've see that it helped Verizon users in the US in some forums online).
I manually changed the carrier to my carrier (Lycamobile) instead of letting the device choose one automatically.

Now, the mobile data works as I'm obviously not roaming, but it doesn't work great and I also have to be on roaming mode enabled, which is simply wrong.
Is any one familiar with this behaviour? Thanks in advance for the helpers.

Based on your action of switching SIMs I assume your phone is not in a contract. In that case, can you try using the LycaMobile SIM in some other mobile and use some other SIM (one from Lyca and one from another) in your Note 3. This is to rule out SIM based issues.

Great idea, will give it a shot today.

You will find it hard to believe, but the only thing that helped my peculiar case was moving to another carrier!
Needless to say, I did not leave the carrier (Lycamobile Germany) for this reason, I left it because they had bad service and a bad product.
Again, nothing helped, nor did the carrier's finest technical advisers could determine why this was happening.
So here's to 7 months of roaming coming to an end.

Try Switching your network mode to manual head over to the Settings>Under wirless and networks> tap more settings>Mobile Networks> Network operator> Search for the Network again now after searching select the appropriate network. This keeps happening with my device too there are actually two Mobile Networks, it usually arises because you may be living in border and somehow the signals from other Lycan network, I am sure you are doing the same, I know its weird but I guess you can't help it its up to you carrier, you could give them a call about it.

Thanks, but choosing an operator manually is one of the things I've tried several times with no luck.
Calling their call-center would probably be my last resort, given the fact that the probability of hitting an English speaking representative is very low here.

Well, in that case I would say try walking down their nearest store. I am sure their representatives can talk with you in english, and yes have you tried checking their site for the online support option (If they have?? )

Yup, they have a retailer nearby, I'll do that, too, thanks

Remove user account in Android 5.0.1 on Galaxy S4
I have a Samsung Galaxy S4 with Android upgraded to 5.0.1. There is a GMail account added that I've linked in order to install a specific application (Google Domain Policy) and now I want to remove that account in order to pass the phone to my co-worker.
I've gone to Settings -> Accounts and the account is listed there (as a Google account). I can tap that and get to privacy and sync settings but I can't see any option to delete the account. I've tried tapping, tapping and holding, double-tapping, swiping and everything else that happened to cross my mind but to no avail.
How on earth do I remove that account from the system if there's no delete option visible?

Click image(s) for larger versions

/data/system/users/0/accounts.db keeps the web accounts info. Remove the account entries from that file, restart and the account would be gone from Settings -> Accounts. This definitely needs root access.

I have spent weeks looking for a solution to this and finally this post helped me! It was so far from obvious and it felt like Google wanted me to keep the account by force lol.
Anyway, what I did was go to Settings > Accounts > Google, clicked the account I wanted to delete, the Sync menu option opened and this is where I always got stuck. Through this, I realized I had to press and hold the menu button on the bottom left side of my S4 to get another menu pop-up with the options of canceling sync or deleting the account.
Finally! Hope this helped.

Mine has no menu button. The following worked for me on a Galaxy Tab: 1st: Settings > Accounts > Google > Sync. 2nd: Disable all syncing. 3rd More > Remove Account.

Thank you this solve my problem.

Nice. But with latest 5.0.1 update, you must tap on bottom left button and not hold it.

In order to remove an user account you need to perform:

Go to device settings (As shown in the question).
click on accounts Tab (3rd in the option list).
Click on Google Account (select the account which you wish to Remove).
First you need to Stop Sync (As done in question "synchr. wylaczonaa").
On Samsung devices these options are shown by pressing and holding the Left soft key beside home Button.(shown using red mark in image below).
Click on Remove Account.

I would suggest read the above steps and you are good to go.
https://www.youtube.com/watch?v=fLLwoZhqFVg

It didn't work exactly the same way as in your link but it pointed me in the right direction. I had to go to Settings -> Accounts, then tap the Google account, then press the 'menu' button at the bottom of the phone and only there I have found the 'delete account option'. Probably logical but totaly unintuitive, at least for me (I don't use Android, so I'm not used to its different quirks). In Android 4 on identical phone it was much, much easier. Thank you, anyway, you've pointed me to the solution.

This answer doesn't work.

Please explain the steps in detail, I've undeleted this since you seem willing to do so.  Thanks.

You have to single tap left button. Not press and hold!

Thanks, it save my life..

Setttings- Accounts-Google- Tap the account you want to remove- it will open sync settings for that account- tap the bottom left touch button of your phone (out of three touch button in the bottom, the right one which resembles 3 horizontal parallal bars)- a menu will be appear (sync now and Remove account)- tap remove account.

I just tried several times and finally found the solution with my s4 to remove the GMAIL account.
Settings --->
Accounts---->
Google------>
select the account need to be removed
it will be redirected to sync settings
click menu touch on bottom of the phone
select----> remove account

This might help. You need touch on menu icon i.e in lower left corner to see sync now an remove  account.
https://m.youtube.com/watch?v=A5P67EFz92s

Might want to outline the steps in your answer in case the video becomes unavailable.

I tried all of the above but nothing works, my phone doesnt have the menu button on the bottom so there was nothing to click on, but here is how i did it.
Settings > Accounts > Tap on Google > Search > Accounts and Privacy > Sign Out
very very cumbersome but finally figured it out! should have been easier than this.

Xperia SP boot loop into flash mode
I have an Xperia SP, and it's stuck in a boot loop after some faulty manipulation. I only see Sony's logo, and plugging the phone to my laptop sets it to flash mode automatically for around 20 seconds, before restarting to connect again straight into flash mode.
How can I fix my phone?

On SE sites, it's perfectly fine to answer your own question, even our help center states so – but answers should be posted as answers, not as part of the question-post (and answers will be "accepted" here instead of prefixing the title with "FIXED" – we're not a forum). Mind [edit]ing that out of your question, and move it to a separate answer? Thanks in advance!

Fix this in a minute

Great, thanks! Just hoping you pick the right minute (not one too far into the future ;) // Btw, as pointed out: consider "accepting" your answer then (clicking the check-mark next to it), so it shows up as "working solution".

To solve this boot loop issue, start by flashing this kernel via FlashTool, switching your phone into fastboot mode. The best is to follow the original guide I guess.
Then, you can follow this tutorial to install a custom .zip file ROM again, allowing your phone to boot again. You might need to upload the .zip file directly onto your SD card.
I hope this helps.

Restoring HTC EVO 4G to stock
I bought an HTC Evo off someone and they had it rooted, but for some reason 4G isn't working. I'm not sure if it's because they rooted the phone and it now has wifi tether (I don't know too much about rooting and ROMs) but could that be the reason why 4G isn't working? If there's a way to fix it I'd appreciate it.

Root access is unlikely the problem, but you can go back to stock and see what happens. Best and surest way back to stock is flashing a .sbf. The .sbf is the stock image provided by the retailer. If you're on Windows, you'll need RSD Lite to flash I believe. If on Linux or OS X use sbf_flash. You'll also need the .sbf for your particular device, but I'm not sure where the Evo images are; Google can probably help.
But again, I'd blame the network before an issue from root.

HTC devices don't use RSD Lite or .sbf files. That's a Motorola only utility, AFAIK.

This walkthrough is the best I've seen on restoring an EVO 4G and removing root. It walks you through, step by step, and gives you everything you need.
And yes, rooting or ROMs could have caused the problem. If the rooting done in a way that manipulates the Wimax partition and source, you may be in for trouble. Also, some ROMs simply do not support the EVO's 4G radios, such as the AOKP ICS ROMs.

Google two-step authentication and Android lock screen
After many failed screen unlock attempts, the user is required to enter the Google account password. That's a good idea.
But what if I enabled Google's two-factor authentication, and then entered the wrong pin/pattern/password two many times? How do I unlock my phone now? How do I login to Google on another machine, when my phone is locked and I can't receive SMSs?
Is there anything very obvious I'm missing? Am I supposed to carry a printed version of Android's application-specific password in my wallet?

I've locked myself out of my phone, on ICS, had 2-step verification and all I needed was my actual password once I got an internet connection to work. Maybe I'm a special case?

You would have to use your emergency backup codes you should have printed out: Backup Code Page.
These are one-time use codes that Google recommends you print for emergencies to access your Google account to unlock your phone.
Additional Information for methods of gaining account access.

Can I enter a backup code in my phone? I thought I can only use application-specific passwords.

No, you cannot use a backup code to directly log onto your phone.
When your phone locks due to too many invalid entry attempts it sends an email to your registered Google email account. The backup codes allow you to log onto your Google Account via a browser to access the email to unlock your phone.
The backup codes are not necessary if you are within your 30-day verification from last entry on the computer.

To regain access to your phone, first you have to regain access to your account on a computer.  Like Dylan said, this can be done using your one-time backup codes.  (You saved those codes, right?)
Once you've done that, generate a new application-specific password.  (https://accounts.google.com/b/0/IssuedAuthSubTokens  or  Account settings -> Security -> 2-step verification settings -> Manage application-specific passwords.)  Use this new password to log into your phone.  You can safely revoke the old application-specific password that you'd previously used on your phone.

Insufficient storage in Galaxy Tab 3 8.0
My Galaxy Tab 3 8.0 is showing insufficient storage with Applications at 11.6GB.
When I add up all of the application storage requirements I get about 0.75GB.
I supposedly have 49MB available but cannot install a 7MB app. Any ideas on what's going on here?

Well, since 0.75GB is equal to ~750MB, I think that there may be an accidental typo in the question. Or I might be misunderstanding something. Are you saying that the app is a 0.75GB app, or are you saying it's a 7MB app?

Can you add a screenshot of your storage menu and also name the app you want to install?

S3 battery not work after water damage
I dropped my S3 in water and the stock battery stopped working. I didn't know how to fix it (I tried drying it with a hair dryer but it did not work) so after comparing prices and discounts I bought a new replacement battery from MPJ and have used it for a month already.
It appears to work just as well as my stock battery. I don't know it's actual longevity but it works OK so far. Since I ordered from an official website, hopefully it's not a fake one...
I still want to fix the stock battery though, can anyone help me?

Using a hair dryer for that is, next to put it into the sun and after putting it into the microwave, one of the biggest mistakes for this task. There are plenty of better ways (including putting it in rice). As for "how to revive a dead battery", this isn't really an Android specific issue and thus not covered on this site, sorry.

Bowl of rice ftw will do the trick, but as @Izzy pointed out, classic! Someone here in Dublin lodged a complaint about Samsung S3 exploding when exposed to sun, Samsung execs panicked, flew over, to take it back to investigate, roped in help with fire brigade to investigate, transpires, that the guy actually microwaved the S3 to dry out after water exposure, when exposed in direct heat, shorted out the radio and "exploded"... got caught out in the end!!! There was a big thread on irish boards about it and had to publicly apologize for the uproar in the first! true story bro

Regarding the safety: Dispose of the dead battery. The li-ion part itself is sealed and probably unharmed, however there's also the charging/supervising circuit: That got soaked and due to the battery voltage, electrolytic corrosion set in and probably dissolved pcb paths already.

Basically, you can't. The charge/protection circuitry in the battery probably got damaged by the water, and you're done now.
Count yourself lucky that it was only a new battery that you needed and be happy.

What happens when using a cellphone when charging?
What happens when a phone is being used with the charger connected?
Will it take power from charger and save the battery usage?
OR
At one end, the charger keeps charging the battery and at the other
end, phone discharges the battery simultaneously?
(I am using Sony Xperia SP with Android 4.2.1)

As using the device also uses some power, the device cannot "charge with the normal speed" at the same time. It will however primarily use the external power source for its consumption. Depending on whether you "consume" more power than the source can feed, either it compensates by taking whatever is needed additionally from the battery, or feeds whatever is left to it.
A side effect described in the other answers already is true, however: the device will get "warmer" this way. I already described that in another answer:

Recommendation for cold days to get warm fingers: Take your device with both hands, plug in the charger. Now stream a HD video from youtube via 3G, play it fullsize, and in the background do some video recording which in parallel gets uploaded via 3G. CAREFUL !!! Wear gloves... #-)

The answer is :

Your phone is charged no matter what.
But at a slower rate than normal.
Making it warmer than normal.

"No" to #1. If your actions require the same or more power than the source can supply, the battery cannot be charged – but it will discharge slower, as the device primarily uses the external power source. "Yes" to the other two points, however ;)

Your phone charges with the normal speed or rate.
And it makes your battery heat up more and nothing else.

How is your answer different to Parag_Baji's? Also the charging current is split into two parts: The current needed to power the device and what's left goes into the battery. So, it charges slower than normal. If you use a power hungry app (e.g. navigation or a 3D game) it may even discharge your phone (at a slower rate though).

how is my answer different, because i have seen battery full notification while charging and playing heavy game (temple run)

It depends on your usage. Do a heavy download over LTE, play a power hungry game and set your screen to max brightness and you'll see the effect. Depending on your charger type and the charging circuit in your phone, it will surely slow down charging or may even discharge. My Galaxy Nexus is capped at 1Ampere charging current and does discharge when playing ingress, for example (the phone uses more than 1A to operate, then, ie. 1A from the chrager, the rest is drawn from the battery).

May be you are right, but I never got low battery alert while charging is on, no matter what I am doing on my phone. At least not in my lg optimus. That's why I wrote above that your battery is always charging when plugged in.

Yeah, it's just that operating the phone and charging the battery both compete for power from the wall charger and the former gets priority. If the operating power consumption tops the wall chargers supply, the rest must be drawn from the battery. Example: http://android.stackexchange.com/questions/24232/battery-drains-even-when-plugged-in-while-using-nav-app-on-long-road-trips or http://android.stackexchange.com/questions/418/what-causes-battery-to-drain-faster-than-it-can-charge or http://android.stackexchange.com/questions/25008/whats-the-safe-limit-on-charger-output-for-a-galaxy-nexus

How can I reset the Play Store content filter pin?
I have forgotten my Google Play Content filter pin and would like to reset it so I can download some apps that are being blocked.
Does anyone know how I can reset the pin?

This article suggests that it can be disabled by clearing the app data for the Play Store. I'm not sure if that's still relevant though. EDIT: Confirmed it works on Android 4.4.

You can reset the Content Filter pin by clearing the app data for the Play Store. This will clear the pin and also remove the filter.

Go to Settings > Apps
Tap on "Google Play Store"
Tap the "Clear Data" button.

A lot of storage space used by 'system files'
I have a problem of huge storage space missing in my newly bought Galaxy Tab 2 tablet.
It is the 16 GB version, but even after resetting twice to factory settings, the available storage space remains at about 5 GB, with the remaining 11 GB inaccessible, because it is "used for Android system files".
I suspect that there may be back-up or batch files from the previous installations that Android does not remove when I restore to factory settings.
Does anybody know in which directories I should look, and how I can delete the relevant folders to free the expected 6-7 GB of remaining storage space that I need for my applications?

Samsung devices are 'known' for their excessive use of internal memory for Android system files and Samsung's own programs (bloatware?). To free this space you'll need to root the device and put a slimmer ROM on it.
Rooting is a practice which requires some knowledge what you're doing and it will void your warranty. If you have no idea what rooting is, I would recommend you to stay away from this practice since it can not only void your warranty, but also render you device useless (so-called 'brick' it). If you do know what rooting is, then you'll also know which sites to use for this, so I won't tell them here.  Hope you'll understand I'm trying to avoid inexperienced readers from doing things to their devices which they regret. Good luck! :)

As for what rooting is, and important related questions, we have a nice rooting tag-wiki – so you're correct to not going into details on that. Besides, there's also one for "rom" :) And yes, Samsung reserves quite much for /system: about a 3rd would suffice. They just want to make sure to have enough reserve for future updates...

Hi, there. Thanks for your reply. However, I find difficult to believe that Android ate 6 - 7 GB of space for system files. As this tablet was bought second hand, I think here there must be something else, like a hidden partition, or something like this. Anyway, I hope the tablet is still under Samsung warranty, as I'm not going to root it. If not, it will be sent back to the seller.

@Izzy Thanks, pretty new here, so didn't think of it myself to include the tags! :)

No problem, that's what we "seniors" can do for you to get you started :) @user47108 It's not Android ate the space for system files, it's Samsung reserving it. And yes, they do that; it's not the first time I've read this.

@user47108 Since it is second hand, you could try and factory reset it:
Settings > Personal - Backup & reset > Factory data reset
Be sure to copy the photos and other files you want to keep to a computer first, because it will erase all data. Mind you that the chance of this freeing up space is kinda small, since Samsung is known for taking up lots of space.

How do I answer an incoming call on my Karbonn Smart A10?
My new Christmas present is straight out the box... It's my first touch screen mobile.
I've put in my SIM and copied some of the contacts. That's it, that's all I've done. I get my first incoming call and I can't answer it - I'm tapping everywhere on the screen. I had to call the caller back once the ringing timed out.
I've read through the quick start user manual but there is no mention there.
How do I answer the call?

Every phone is different, but my first guess is you would have a "Swipe to Answer" phone, where it displays a ring/circle/object near the center of the bottom half of your screen. You would generally drag the circle to the right to answer, or to the left to decline the call.

Thanks so much for your reply.  Your description is perfect.  It would seem that I need to go back to the shop because the circle part is rarely active:  doesn't give the red and green options and wild tapping didn't help :)  The next one should be better.  I hope!

I don't know where to comment but thanks a lot, bmdixon, for fixing up my question.  I really appreciate it and also the karbon-a10 tag. :)

@bmdixon:  please amend the typo on the tag - karbonn should have 2x"n".  I only noticed this when I search for the tag again today and it didn't come up.  Sorry if this is not the right place!  Can't see how to contact you.

Error when downloading application from the play store: RPC: S-3
I just got an Android tablet and when I try to install an app on the Play store it says:

error retrieving information from server [RPC:S-3].

I've tried clearing the data for the Play Store app & turning it off & back on but it didn't work.

Try going Settings>Accounts>Google>Tap your account> tap three dots in the upper right (or press menu button) "Remove Account".
Go to "Settings"->“Applications”->“Manage Applications”
Select "All"
Scroll to and tap “Google Play Store”
Tap “Force Stop”, tap “OK”, tap “Clear data”, and tap "OK".
Tap the Back button to get back to the applications list.
Scroll to and tap “Google Service Framework” (or Google Play Services)
Tap “Force Stop”, tap “OK”, tap “Clear data”, and tap "OK".

Now reboot (switch on & off) your device.

Try going Settings>Accounts>Google> Tap your account> Three dots in the upper right (or press menu button) "Remove Account" ... then read your account .. then if you want, clear Play store cache and data and try it.
Worked for me!

+1, why don't they just invent a button that recomputes all caches. hilarious.

@Fiksdal you are right, now it works, the problem was that the USB connection was not detected, I get it out and entered it again and it works.

@kouty Wireless works or USB works?

@Fiksdal USB, at init I made hotspot only and not worked, I added USB and it works. I see that usb only also works

@kouty I don't know what you're trying to say, but I'm glad it worked.

@Fiksdal at and USB alone the way which worked

@kouty Alright.

Mi Max 2 Xiaomi apps as default immutable setting
I'm using a Xiaomi Mi Max 2 phone.
At the last time I was able to open links with a browser of my choice. But now, the "browser" only is imposed. Additionally, there is a lot of Xiaomi tools and apps that appeared, as App Vault, shortcuts and calendar from Xiaomi that take the control of my phone.
How can I get there out?

You might be able to disable them. See https://android.stackexchange.com/q/56620/96277

Thanks, but my phone is not rootable @Firelord

Stuck in boot after encrypting
Device Name: Lenovo K3 Note
OS: Lineage OS 14.1 (Android 7.1)
Recovery: CWM ; Accessible
Bootloader Status: Unlocked and Accessible
Root Status: Rooted
Accessible via adb

I used the Android's Encrypt Device option to Encrypt my device. The Encryption Process went smoothly with no errors. The device then rebooted and asked for pattern. After I entered the pattern, the device starts booting but never completes booting. While it is stuck in the boot animation, it is accessible via adb. I can also access the recovery and bootloader via adb reboot recovery and adb reboot bootloader.
I tried clearing cache and dalvik. Both proved of no use as the problem persists. The only app that I can think that might be interfering is SnooperStopper. I however can not uninstall it via adb as it is a Device Administrator.
Is there a way to either decrypt my device via adb or to boot it successfully.
EDIT: I found that there is a missing link from /mnt/user/0/primary -> /data/media/0/ which broke the symlinks /sdcard/ and /storage/self/primary/. Manually creating the symlinks however proved of no use nor did adding them to start-up by adding the command to /data/local/userinit.sh which was called by /etc/init.d/90userinit.

You will almost certainly need to wipe the device and start over.

I added an edit. Maybe that would help.

I finally ended up wiping my device and then restoring from a backup.

Installing Play Store on Chinese Samsung Note 3
I have a Chinese Note 3 running Android 4.3. It doesn't have the Play Store which defeats everything that made Samsung dominate the smartphone space. I can't download GMail; I am stuck with a browser that uses Baidu for search; there is no Facebook and Twitter. It could almost be just one big feature phone outside China.
I would like to ask how do I install the Play Store and get the other Google services on the device. I searched the internet and it always tells me to root the device.
Could anyone enlighten me on how does rooting the device be able to get the play store running again?
Could anyone provide the steps in installing it after you rooted the device?

Please let me know your Android version?

@Asif Andorid verion 4.3

Upon searching at XDA, few had success in rooting Galaxy Note 3 (Chinese version) SM-N9006 and installing Google PlayStore via CWM. Nobody there has mentioned why root is required to flash CWM via ODIN. My guess is it is required to flash CWM by ODIN. CWM is required to flash GApps.
Please follow the instuctions in this thread at XDA where users have reported success with CWM and PlayStore functionality.
There is another thread which uses a safe method for rooting without disturbing Knox. I would recommend trying it out before following the first link for flashing GApps.
Disclaimer: I do not own this device and any answer provided by me is found from internet search and the rate of success may vary. Please read thoroughly before proceeding to avoid bricking your device.

@Mr A, there is no other way to install google apps without root. It is happen because the system need to install gapps to system folder. You only need to root and flash custom recovery base on your device. After that, you can flash the corresponding gapps to your OS version through custom recovery.

This is overly broad and not necessarily true in many cases. Although for the Note 3, it seems to be true.

@dotVezz for which devices is this not true? GApps require root to be installed (package installer must be installed as system app, or it cannot be used). GApps come as update.zip to be flashed via recovery, which requires a custom recovery on most devices (signature check). There might be some exceptions to the latter, but not to the former.

@Izzy, Hmm... I may be confused, but I was pretty sure that in cases where a custom recovery can be installed via fastboot, odin, etc, root is not necessary. I'll have to test my theory now. UPDATE: Yeah, I can install gapps without root on my Nexus 5, and I'm fairly sure that I've done the same on various other devices with recoveries flashed over fastboot and odin.

@dotVezz I didn't work with fastboot yet, but I imagine it works with adb sideload or the like? Maybe you could make this a full-fledged answer – either here, or (to make it easier to find) to our central How can I install the Google Apps Package (Play Store, …) on my Android device?

@Izzy: I'll probably just add the fastboot details to the wiki answer as it's not really enough extra information to justify a full-fledged answer. Basically just involves running fastboot flash recovery TWRP.zip, then installing the gapps in recovery mode. Still, this means an unlocked bootloader is necessary.

To get GApps I just have to get it on another device?

How can I root my Sony Xperia Tipo Dual without a PC?
I need to root my Xperia Tipo Dual, but I can't connect the phone to a PC, Is it possible to get root without connecting it to a computer?

You may want to look at this question: How Can I Root my Sony Ericsson Tipo Dual?
The short answer is no, you need a computer.

Actually that would be hard as Google has banned applications which provide rooting for device warranty concerns.
So actually you should search a bit on Google and you may get a site providing easy rooting tools. but you will need a pc.

It's exciting to have new members to give answers around here! Unfortunately, in this case, the requirement for a computer has nothing to do with a ban on the apps themselves - For example, the CyanogenMod One-click app is still available, just not in the Play Store. But the thing is that those apps also require a computer and a companion application to be run on the PC.

I just talked about the point and that is PC is always needed for rooting, One click app has nothing to do with that.

However, the requirement for a PC has nothing to do with any ban. It's entirely a technical requirement.

that was extra information on how onboard rooting applications are not available

What is master key vulnerability in android?
What is master key vulnerability in Android? From looking at a few different sites, I understand that it is bypassing the authentication provided by signing of apps.
How can I detect an app is vulnerable to master key vulnerability. Can anybody please give an example?

You've already described correctly what that "master key vulnerability" is about. If your only source for new apps is Google Play, you're most likely on the safe side; danger from this seems to be restricted to side-loading via unknown-sources.
However: If you want to check whether your device is affected, there are several apps out there which promise to do this. E.g. Belarc Security Advisor describes itself as checking for several hundred security flaws known on Android (including the master key). If the check is "positive", there are also fixes available, like Master Key dual fix or the Master-Key Security Patch (a module for the Xposed framework).

internet slow on my tablet

I know this question has been asked over and over and I have searched
  for an answer but no one seems to have an good result.

I have a new Prestigio Multipad 10.1. It's a nice tablet but I'm having trouble connecting it to my WiFi. I can connect but it's slow or never seems to receive any data.
I've tried a lot but I haven't a clue why other devices I have work. My android phone, my laptop, iPod etc.
I bought two of these and they both have the same problem.
There must be a setting which will correct this problem.
I have tried changing channels, I have tried a WiFi fixer but:

Google store just times out.
Chrome never comes back with any results .

I'm pulling my hair out. Please help.

You haven't specified what you have tried so we'll end up recommending things you've already tried. Start here I guess: http://www.guidingtech.com/13028/solutions-android-wi-fi-problems-common/

See what RossC said,... and, when you are too far away from your access point, the wifi module of your mobile phone might lose packages that are sent to the access point, as wifi modules of smaller devices usually have a weaker sender / less range than those of larger devices.

I can't say that I have an explanation for you but it seems to be the nature of the beast. On my wifi network, my smartphone and my tablet get about 10mbps slower speed than my computer. I have no idea why but that's consistently the result so that must be normal.

The manufacturer of your tablet may have put a chip for older standards of wifi, such as N or G. The computer will always be faster as it has larger antennas if on wifi, or is wired through the modem to the router to the computer using Ethernet. Wired connections are always going to be faster than wireless.

Enable autoplay HTML5 video in chrome
In my project I need to autoplay a HTML5 video in the browser when the page is loaded. I have tried a several javascript solutions but none of them work.
I read that the android browser blocks autoplay to prevent downloading a lot of data. Can be this blocking feature be turned off in browser/chrome/operation system settings?
I cannot find any working solution for how to enable autoplay. I have searched plenty of stackoverflow posts and many other sites ...
I am using android 4.1.1.

To close voters: this question seems legit. Though it's the dev asking, the question itself is not about development, but about browser/system settings, and thus of interest to "normal users" as well (as long as Peter is not asking about doing this from his app in a programatical way, of course).

Bad news it seems. Bug report on Google code
The most relevant post is this:

Yes. It is as design. "autoplay" is disabled for Chrome for Android

It seems that Android 4+ changed the requirements for the play() method to require user interaction.
 Article on this issue
It's worth nothing that many comments refer to getting it to work with a hack/workaround, only to find it works on some devices and not others.  Stack Overflow question on the coding side. In this example the answer mentions:

sample code that works on HTC and Samsung, but not Galaxy Nexus 4.1 (requires user interaction to play)

This seems to suggest, even with a workaround you have no guarantee it will actually work on a particular device / version of Android.
Apple have imposed the same restriction in Safari and iOS in general.

This can be turned on/off in Chrome using flags. This is on the user end though and cannot be change in the browser from a website or app.
You can also do this in your own app using the api for webview or websettings and make "getMediaPlaybackRequiresUserGesture(false)" it is by default set to "(true)"
http://developer.android.com/reference/android/webkit/WebSettings.html
In chrome you must go to chrome://flags then go down about 3 screens to

Disable gesture requirement for media playback. Android
Disable user gesture requirement for playing media elements. Activating this will allow autoplay to work.

Can someone give me their Nexus 5 sbin directory?
I'm in the process of trying to root my phone without the screen (dropped it in water). I went to copy the su binary to the /system/sbin/ directory and left off the '/'. So now I just overwrote my sbin directory with the su binary.
Can someone post me their /system/sbin/ directory so I can restore it?
Thank you.

Depends how desperate you are for the files. So here is a way to get the files yourself incase nobody else loads up the actual files for you.
You will need to do all this on a Linux box of your choice. Best way to approach this is to download your image file from google
https://developers.google.com/android/nexus/images#hammerheadkrt16m
As you can see at the moment there are two builds for the Nexus 5
Once you download that file unzip that file until you find the img files. There will be one called system.img which will probably contain the files you need.
Unfortunately the img is compressed any you will need to uncompress that image first.
There is a thread over here that discusses this http://forum.xda-developers.com/showthread.php?t=1081239
Once you have the image that has been uncompressed you should be able to mount it on a loop back device
mount -o loop system.raw.img mnt <- Create the mnt directory first
Then that mounted directory should show you all the files

How can I select the apps to sync when auto-sync is turned on?
When I turn on auto sync it sync all my accounts like Google, Twitter, Facebook, BBM etc.
How can I set auto sync to sync only selected accounts so that only my Google or Twitter account will be sync?

Gee, Bill. I'm surprised you're not using a Windows phone.

Did you take a look at Settings → Accounts & Sync? (I'm not sure about Android 4.1+, but at least on my LG Optimus 4X this setting is there)

Accounts & Sync (click image for larger variant)
As the screenshot shows, here you can define what to sync. Green arrows to the right show what's to be sync'd, gray ones what not. For some apps, you even can tap the app to specify it more detailed.

What version of Android/manufacturer-added skin is that in your screen shot? It doesn't match up with my vanilla Android 4.2. (In fact, there isn't an "Accounts & Sync" option in settings.)

I cannot check with 4.2, as my LG O4X still runs 4.0, and it has "Accounts & Sync" in settings. OP didn't state which Android version he refers to – but you're right, I should state mine with the answer (updating...)

@AlEverett vanilla Android 4.2 & 4.3 have an "Accounts" heading in Settings and just list all your sync accounts under that heading in the main settings screen. You can tap to open those accounts and most of them should have sync options that you can un-tick.

And it's still there with Android 4.4, by the way. Most likely also with later versions.

For Android 4.2+:

Accounts -> Select account -> More (at the top right) -> Sync.

Android update and android mod
I want to create a custom boot image for my Android. When I will update the System OTA I will lose my mod?

That very much depends on the OTA and what it includes: it might only replace/add some files, but it could as well replace an entire partition (usually /boot and/or /system).
So yes, an OTA system update might overwrite your "custom boot image" – though not all OTAs will do so.

Why is Google Play Books incompatible with my Nexus 5?

Today, I have bought a Nexus 5, and I want to download Google Play Books from Google Play, but I get the prompt message as seen in the above image.
Why am seeing this message and how can I install the app on my phone?

Isn't there already a Google Play Books app on your Nexus 5? The one it comes with may not be compatible with the one on Google Play.

It might not be available in your country.

@roxan Google Play isn't available at all in China, so the error message is a little confusing in that case.

Thanks guys,
When I use VPN network access Google Play, Everything is OK.
The Google Play Books default disabled on my Nexus5. If I use VPN network login Google Account that I can enable it.

If you hit the install button and mouse over your device on the list, it'll give you a buy more detailed reason why it is incompatible.

Use APK Downloader to download the .apk file, which you can then transfer to and install on your N5 like any other app.

Phone forgetting networks after turning off wifi
Whenever adding a new wireless network, android seems to forget the network after disabling then re-enabling wifi. I am forced to manually connect to the network and enter the password each time. This also happens with open networks. The problem occurs on any wireless network, at home, work, public networks, etc.
Further inspection on the /data/misc/wifi/wpa_supplicant.conf file shows "disabled=1" added to the end of each network.

click image for larger version
This has been going on for weeks. Any help would be much appreciated.
Phone: Nexus 4
Version: 4.4.4

I have had this problem for almost a year now. I have Nexus 5 and all the latest Android OSs. I had the exact problem, and it was really annoying. Whenever I turn of wifi or phone, it keeps forgetting my home wifi and all newly added...
Solution:

Settings > Wifi > Saved Networks

The list showed over 120 remembered networks....
I travel a lot, and it was mostly hotels, bars etc.
So i didn't need them and I have deleted over 100 networks.

Problem was still there. When i turn off wifi again - the same.

I repeated the step 1. There was again list of over 100 saved networks(different ones)...

Repeat step 1 over 5 times!!!
Now I have only 20 saved networks.  And when I add new network - the device remembers it!!!

I guess that the problem was - when you remember new network - it is there in your phone. When you turn off wifi and back on - it tries to overwrite it on your google backup account ...
However - I am happy again! This was really annoying.
Cheers
Marko

I noticed a similar problem on Dell tablet where it would ask for the wifi password and connect, but forget it every time.
I would have tried checking the wifi system files, but it wasn't rooted, I ended up solving the problem with this tutorial.
The short version for those with adb installed, is:
1) adb backup -apk -shared -all -f ~/mybackup.ab (or wherever you want to save the file). Make sure developer mode and debugging is enabled in tablet settings.
2) Make sure the backup was created, should be about the size of used space on the device. Now do the factory-reset in settings.
3) After doing the initial-setup procedure on tablet, make sure developer mode and debugging is enabled in tablet settings, then on the computer run  adb restore ~/mybackup.ab (or wherever you saved your backup)

Icon issues in Google Play Store 4.8.20
I'm running Android 4.2.1 and recently the Play Store app updated to version 4.8.20 and since then I'm facing icon issues within the store.

Click for larger version
As you can see, there's a weird black background for every app icon, this is the case for every page within play store, all the icons have this kind of background. I once tried un-installing Play Store updates and fell back to pre-installed version 4.1 of Play Store, which solved the icon issues (but left me with older version of Play Store). And obviously, the Play Store again updated itself to latest version and I again have same issue.
Note that there isn't any such problem on my different Android phone (which is running Android 4.2.2 but has same Play Store version, 4.8.20).
I've tried clearing Play Store cache, App Data, and as said earlier, uninstalling updates (which momentarily solves the problem), but nothing seems to solve the problem with this version of Play Store, only option I haven't tried is hard resetting my phone, which I want to avoid.
Is this a known bug with this version of Play Store? what are the options I have to fix this?

Try uninstall updates from google playstore at your phone settings.Clear data and open it.Uncheck box"keep me up to date"...I know this is an older version but u can wait for the next update..

Gmail doesn't show mail when opened from notification bar

Click image for larger version
I waited for 9 hours, nothing changed.
For a test, I clicked on a random white area and the Reply function was activated!
So it seems, the mail was long open but the progressbar never disappears. If I press Back and open it inside the app, it shows the letter with no problem.
What could cause this?

This appears to be a bug in the GMail app. I have seen this myself a few times and normally clicking the '<' arrow in the top left and opening the email again sorts it. Other times I have to kill the app and re-launch it.

Does Google know this? How can an application that used by millions contain a bug that prevents normal usage?

Microsoft Exchange ActiveSync - Contacts Storage
I use a Microsoft Exchange account for my business and use a Samsung Galaxy S3.
If I sync my contacts to the phone from the exchange account, are they actually stored on my phone or SD card or are the actually just in the cloud?
I want to have access to all the people, but don't want it to take up memory.  I have over 1,000 contacts and it grows.

The contacts themselves are synced to your phone's internal memory, so they do take up space. The contacts are then updated every time the phone syncs with the server.
If they were only in the cloud you wouldn't be able to access them if you happen to lose the network connection, and contact lookup would be noticeably slower. Also, some mobile network technologies can't maintain a voice call and data connection simultaneously, so you wouldn't be able to match incoming calls to contacts, because the data connection would temporarily be disconnected.

Cannot install some apps in Android 4.1.2
I have a Motorola Razr D3 cellphone. Although I have at the moment 800 megabytes free on the device memory, some apps report insufficient space to perform the installation. I've cleaned caches and removed many apps.
I'm unable to install some software, for example, Aircrack-ng.

What should I check for?

possible duplicate of "Insufficient storage" when trying to install new app

First check where exactly you have how much space free. Storage is divided into multiple locations, such as device storage, internal, and external SDCard (depending on what's available). The "insufficient space" error always refers to device storage, not to any of the SDCards. If your device storage gets low, it doesn't help to have plenty of space elsewhere. See our insufficient-memory tag-wiki for details and first aid.

I have 800mb free in the internal memory. The SD card I have has 32 gb and only about 1gb used. So I do have free space on the right place.

See also: “Low on space” warning with over 50% free / Google Play: Error downloading app - insufficient space / False “low on space” (internal storage) warning on HTC Incredible

I fixed it formating the device. Still this not a solution.

How to recover data via adb?
My phone is huawei u8800 and it keeps restarting as soon as opened. Now it is closed and in adb, I tried
adb backup -all

but it gave the error
now unlock your device and confirm the backup operation

I don't want to lose data. What can I do?
I have CWM, I have backed up but I can't trust that if I reset, it can restore my data.
I can't open the phone so I cant use backup programs.

Problem is, even with adb backup, you need to at least tap one button on the device to confirm – a security measure, so a "data thief" cannot simply "dump" your stuff. // What do you mean by "opening"? Does it hang in a boot-loop, or does it reboot when you unlock the screen?

As soon as it loads beginning screen, it restarts. I can npt even unlock the screen. Sometimes it restarts without loading desktop.

Along with CWM, did you install a custom ROM (like CyanogenMod or MIUI, for example?)

Yes i installed aurorasp and after that restarting started (i did not install any update or apps but restarting started) , i reflashed some roms to solve without wiping data. It  did not work. Once, restarting was delayed, 4-5 seconds.

When installing a different ROM, not wiping can lead to trouble – like you experience now. Did you create a backup before flashing? Hopefully even Nandroid? In that case, the best approach would be restoring that, then do your adb backup (excluding system stuff!), and after a clean wipe/flash you can restore your apps and data from it. For "system data" (contacts, calendars, APNs, etc) you will have to take care separately. Please also check our backup tag-wiki.

No, after this problem started, i tried to install new roms without wiping to solve that.

Device doesn't mount in Ubuntu 12.04
I have an Android device (ICS) and it is visible and perfectly usable via ADB in Ubuntu 12.04. However Ubuntu can't mount it.
I can't find it on /mnt or /media. How is that possible?
I know there are tools for mounting in Ubuntu like Go-mtpfs but I don't understand how the device is connected perfectly with ADB and not mounted in Ubuntu.
Any ideas?

What device is it? My Galaxy Nexus won't mount either - Go-mtpfs doesn't work neither.

ZTE Blade 3. Have you tried if adb works with your device?

Hm, I didn't try to be honest.

Maybe adbfs is a solution for you? That's what I use with 12.04. For details, please see may answer here.

Related (maybe even duplicate): Linux fails to mount Android device in USB MSC mode. Further related: File Transfer: How to transfer files betwen my Xperia Neo (Android 2.3) and Kubuntu Linux? / How do I make my Linux PC mount my Android 4.2.2 phone using MTP? / mounting google nexus s on linux at fastboot mode screen

I'd recommend upgrading to 13.04 or 13.10, which have much better MTP support out of the box.

Android allows mounting of removable media over USB. Before the storage media is mounted on the host computer, the Android device unmounts it to ensure that only a single system has the storage media mounted at a time. That works fine for removable media.
When an Android device has only internal memory without any removable media (like the Galaxy Nexus and newer Nexus devices), the device cannot unmount its internal memory to let the host computer mount it. The Android OS requires use of the internal memory. Hence, mounting over USB does not work.
Some devies with internal memory only (like the Nexus S) worked around this problem by providing a separate storage partition not required by the Android OS. That separate partition could be unmounted by Android and allowed to be mounted on the host computer. Multiple storage partitions make it harder for users to manage their storage space. That is, one partition may fill up first while there is plenty of space in the other partition. So recent Nexus devices come only with a single partition in their internal memory which cannot be directly mounted on the host computer.
With such devices, mounting the internal memory on the host computer can be achieved with go-mtpfs using MTP and FUSE. I have tested the following on Ubuntu 12.04.1.
Setup:
$ sudo apt-get install golang fuse git-core libmtp-dev libfuse-dev
$ mkdir /tmp/go-mtpfs
$ export GOPATH=/tmp/go-mtpfs
$ go get github.com/hanwen/go-mtpfs
$ sudo mv /tmp/go-mtpfs/bin/go-mtpfs /usr/bin/
$ sudo adduser $USER fuse

Mount an Android device:
$ mkdir /tmp/AndroidDevice
$ go-mtpfs /tmp/AndroidDevice &

Use the mounted filesystem:
$ ls /tmp/AndroidDevice
Internal storage
$ ls /tmp/AndroidDevice/Internal\ storage/
...

Unmount:
$ fusermount -u /tmp/AndroidDevice

You can [edit] your post with the added information in your comment. And please also include a summary of the instructions in your answer - an answer should stand on its own without a link (EG, should have instructions), and links are best used to back up what you've said.

@dotVezz, My reputation does not allow me to include more than 2 links in my answer. The questioner said that he is aware of go-mtpfs. Hence I did not give detailed instructions for using go-mtpfs as an answer. He is asking why mounting does not work. He is not asking how to mount.

I didn't realize that low-rep users had a link limit. Still, if you feel that linking to instructions for go-mtpfs is pertinent, then I feel that writing them is pertinent.

@dotVezz, I deleted my comment and add it to the answer.

Backup paid app from Google Play
How can I backup an app I bought from Google Play so that I can install it on my phone later?
I tried to copy /mnt/asec/[appId]-1/pkg.apk but it doesn't work.
Can someone help?

Are you rooted? Titanium backup will do this easily. If not, pulling paid apk may not be possible as ususally Play uses the /data folder which you won't have any access to without root anyway. This is to stop you from copying the apk and sending it out illegally I would guess.

You don't need to back up the app anyway. Once you've paid for the app, you can install it again later, as many times as you like.

You don't need to back up apps bought on Google Play to install later.  So long as the device has your Google account registered on it, you can download and install it from Google Play at any time.

Good reason "pro backup" would be when the other device has no internet connection (wouldn't work either then as payed apps usually need to verify the license online), or just a very limited data plan (save the megabytes of the download by copying the .apk via SDCard locally). So while generally true, there might be exceptions from this rule :)

No argument there, but wasn't really within the scope of the question as it was put IMO.

Nexus 7 rooting and battery life
I rooted my new nexus 7 the other day using the Nexus Root Toolkit.
Before rooting I was able to get about a full day out of a charge and still be at about 20-30% but now my battery seems to drain faster and even drain while I have the screen locked.
Can root affect battery life? Or could it be an application?

What did you root for? Presumably you rooted your phone to accomplish something that couldn't be done without root access? What have you used your root access for? What root-only apps have you installed, what system settings have you changed? There are lots of things you can do once you have root access, some of these will affect your battery life, some won't. It would be make this easier to answer if we knew what else you've done.

I've flashed Cyanogen and ive used root for. Ore advanced features in  Tasker. I also replaced my boot animation and changed soft keys

Rooting the Nexus 7 means that just some additional applications are installed, e.g. the su binary and the SuperSU app.
Both are not active in background, therefore I assume that your battery life problem is caused by a different app that had been updated or installed more or less at the same time.

I'll have to look as soon as I'm off work. Thanks

How to force retrieving app icon for apps downloaded from Google Play?
On my Nexus 5 running Android KitKat 4.4.2, I noticed that from time to time, the apps I downloaded from Google Play would come with missing icon, so it defaults back to the green android robot icon:

Click image for larger version
Two applications that I have found to produce the issue for me.

FLV Video Player
Bayes Theorem

I have yet to figure out a proper solution to this, but I can't be the only person experiencing this issue, so I was wondering if any seasoned android users can help me resolve this issue.
I already tried to do a quick search on android stackexchange, and on google, but I did not come up with a solution that caters to stock android. I did find something similar, but that appears to work only for for Kindle Fire.
Thanks for reading.

Are you using the stock launcher or a custom one?

Managing calls between carrier number and Google Voice, using GV as primary
I'm looking for the best way to set-up/manage my calls between the carrier # and Google Voice as I use both.
I'm using a Samsung S4 on VZW (however I would prefer to use phone/Google Voice/app to manage rather than rely on VZW settings)
I have certain calls go to Google Voice and the rest go to carrier. The problem is that the 'other' calls are many and I was sick of hearing my phone ring all day when I only want to receive those calls at specified times. Part of my solution was figuring out how to set-up call blocking on the S4 (last phone was a Thunderbolt and as far as I knew this wasn't in the settings)
My big problem now is that every blocked call ends up going to my Voice-mail and a lot of them have automated recordings so my inbox is filling up. I'd like to find a way to block all carrier calls, and not allow them to forward to my Google Voice inbox for Voice-mail on a specified schedule.
e.g. Block all calls/VM's M-F 1am-1pm

If the "other"  calls are usually at certain times of the day, you could use Tasker to automate things for you.

Do you have the recipe for this?

I may be able to figure one out for you, but I'd need the specifics of what you're trying to do, and when... On a side note, I've only used Tasker a handful of times, and I'm not, currently, running it on my phone. I'm willing to give it a shot, though.

Rooting Nexus 7 - SuperSU Binary Update Installation Failed
Can someone please help me find the correct SU binary for this device? I am trying to install the SU binary for SuperSU, and I get an installation failed every time.
I have been looking for information on this specific problem, and from what I have read, I may have to download a new binary file and download it through flash recovery (shrug). I thought I would try that, but I cannot find anywhere with information specific to my device.
If you think the problem could be caused by something else, please let me know.
Thanks in advance.

I updated SuperSu from the google play store, and now I am getting the following error:
"There is no SU binary installed, and SuperSU cannot install it."
This seems to confirm that I do need to install the SU binary for my device version, but I still not found where I can find the SU binary.

You should be able to download the latest SuperSU from Chainfire.  Push that to your Nexus 7 using adb push and install it from your custom recovery.  I'm guessing you have that already?

Yes, I just installed "UPDATE-SuperSU-v1.93.zip", and I am still having the same problem.

Do you have a terminal emulator on your device?

I can download one, if that would help some how.

After having the 'no SuperSU Binary' error message I followed this guide :
How to Root Nexus 7 2012 (Wi-Fi) and Nexus 10 on Stock Android 5.0 Lollipop via CF Auto Root
that worked after several attempts.   most importantly  I had to be in the stock rom ( lollipop)  then run the root-windows command.  then  while it says  "waiting for device", I the switched tablet off, then  vol down+power to go into bootloader. Then the magic happened.
hope this helps

Welcome to the Android Enthusiasts! Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. Otherwise, your answer becomes useless in case the link dies. For further hints, please see: How do I write a good answer.

Hope this helps.

How to use a USB cord and a rooted Pixel 4 tablet to root and jailbreak other devices?
I have a Pixel 4 tablet that is rooted with a functional USB and port. I'm trying to figure out how I can use the USB cord and hook it up to the same device that isn't rooted, clean out all of its operating systems, and make it to where it is rooted and install whatever I want. I have no idea what tools I need to use or how to use them if I do.
Can I get any help with this and some educated tips on how to go about doing this?

Possibly related: How to manually root a phone?

So you want to use one rooted Pixel 4 to root another Pixel. The main problem I see is that I am not sure if you can use fastboot from one device to another. Fastboot is essential to perform the bootloader unlocking and for flashing a recovery or modified bootloader.

Agreed. It may be far simpler to buy a cheap Linux or Windows mini-PC, simply to have access to the usual tools for the job. They start at around $200.

@JohnDallman That is way cheaper possible. You just need a Raspberry Pi (1,2,3,4,5,...). If you use it remotely via SSH you could even use it from an Android tablet and the PI headless (no screen or keyboard).

@Robert: I didn't consider RPis because Google don't provide their Platform Tools for ARM Linux, and having those tools us usually important.

Platform Tools to run on Android available here, but with less of a guarantee than Google's builds.

How much does a factory reset help in hiding a device's identification details?
I got banned from a couple of websites like Reddit, and my idea is to use a VPN to hide my IP and then factory reset my Android device so that the website can't recognise the device.
After looking online, there seem to be mixed opinions about whether factory resetting a device actually makes it look like a new device.
When you factory reset, does the MAC address or the serial number of the device change? And otherwise, are websites able to detect this information anyway? I guess a website can still see details of the device such as the OS it's using and its hardware specs, in any case, so even with a factory reset they'd still be able to see that particular information, wouldn't they?

MAC addresses and serial numbers are not accessible by apps or your web browser.

But I think websites could access these details, couldn't they, not being restricted by the limitations of a formal "app" nor those of a web-browser..?

No web browsers are just normal apps are therefore restricted as every other Android app. Access to unique identifiers is restricted to system apps, that was introduced years ago in Android. What however is possible is that websites device fingerprinting, however usually that doesn't allow to uniquely identify an Android phone.

@Robert Thanks for providing a good device fingerprinting link.  I added the link to my answer in case your comment eventually disappears.

In all likelihood, simply changing the IP address will be sufficient.  Banning someone from a website is a little silly and largely pointless because it is trivial for someone to bypass that ban.  It's usually better to limit functionality to newcomers, as Stack Exchange does.
Factory resetting your device is largely pointless.  Sites cannot directly determine a connected device's MAC address (but can potentially do so through a court order or via hack, bribery, or blackmail).
Serial numbers, except in special circumstances, do not come into play at all.
What can come into play is device fingerprinting.  Every device has a fingerprint, some more unique than others.  Generally speaking, the more unique settings/software/fonts/hardware your device has, the more unique your device's fingerprint will be.  Factory resetting will have no effect on your device's fingerprint if you install the same software and configure the device with the same settings.
A larger issue, however, is to take a close look at why you were banned.  You reported you have now been banned from "a couple of websites like Reddit".  The fact that you have been banned from multiple websites indicates that your behaviour is likely unacceptable to the communities from which you have been banned.  Spend some quiet personal time thinking about why you want to be a part of communities in which you are not a valued member and in which you are likely disturbing others.  Occasionally, bans happen because petty small-minded power-hungry people intentionally seek out and obtain the power to impose bans on others.  But if you've been banned from multiple sites, respectfully, there's a real good chance that it's time to take a long and thoughtful close look at the person you see in the mirror.

How do I bypass ADB Error Message and/or delete OEMs
I have a TCL Android phone. I keep getting error messages when attempting to use ADB to debloat my phone. I would love to know why my commands aren't working and what the correct ones to enter are. I was inputting the following commands
First;
adb shell pm list users

Then these exact commands in any given order as I have attempted this several times over now;
pm uninstall -k --user 0 com.facebook
pm uninstall -k --user 0 com.facebook.appmanager

pm uninstall -k --user 0 com.facebook.system

These are the error messages which come up in return.

I hope my efforts in tracing down those error messages will prove helpful for you.
I've found on another post on this website that a quick fix would be to uninstall secure folder. I haven't been able to find any trace of a secure folder on my TCL Android. Nor did I see "disable monitoring permissions" in my dev settings which I had seen written as a quick fix on another post on this website.
Any help would be much appreciated I have 32GB to myself on my work and personal phone and the OEMs are taking up 15GBs of those.

You have only posted the error message and stack trace but forgot how include the exact command that causes it. How should we know what mistakes you made on entering the command if you don't show it to us? Also it would be good to know the device model and Android version. Last but not least why do you post the same error message twice - one time was more than enough?

Im so sorry that I wasn't able to tell the difference between two walls of error messages. If you read closely im asking what the correct command to enter is. If that code feedback does indeed indicate that I made a mistake that would be lovely of you to share, so that I could know that I should include all the 7 different ways that I imputed the command. Why do you expect me to be a genius in this field and instantly know everything needed when asking the question without having been given ANY formal training. How very demeaning of you.

Please keep calm. I understand that you might feel attacked, but on the other hand, troubleshooting Android devices is very difficult because Android is open-source, and manufacturers can and do customize their Android OS, thus what you saw and tried for other device models might not work on your device (I assumed you read the one specifically for Samsung devices). This is why we expect the asker to give information as detailed as possible in the first place since extended troubleshooting to get enough details may also take time before getting an acceptable solution.

Please remain calm Andrew. If you'd like to expect something of any other human being, you need to first inform them of that beforehand. You may not expect any other human being to do ANYTHING that you haven't informed them that their expected to do, understood?

Prevent accidental touch while speaking on GrapheneOS (AOSP)
I've got a Google Pixel 8 Pro running GrapheneOS. When I'm on the phone talking to somebody and hold the phone to my ear, it very often accidentally registers taps. This e.g. leads to activation of the flashlight or Bluetooth by the slide-down menu. Locking the screen after answering the call does not help, probably because the slide-down menu is accessible anyway. I cannot find any setting to prevent this. Does anyone have the same issue or any idea of how to fix this?
I used the app Sensors Toolbox to check whether the proximity sensor works as it should. And it does. However, it only detects small distances at the top of the phone (where the ear should be during the call, which is not always the case). If the phone detects a small distance to the skin during the call, the screen is deactivated, but is activated if the phone slips a little from that position. Is this normal?

Most phones have a proximity sensor that detects if the phone is close to the body (distance about 5cm or less) and then disable the screen. Use an app like Sensors  to test availability and functionality of proximity sensor.

I've just installed this app and the proximity sensors seems to work. I've edited the question.

The proximity sensors I have encountered were always "digital" - 0 or 1 which means a proximity of 0 cm or 5 cm (tested on my Pixel devices).

I can confim that. Maybe it's just my way of holding the phone :(

Permanently disable Android adaptive notifications on REVVL 5G
I have a T-Mobile REVVL 5G. I want adaptive notifications set to NONE permanently.
Adaptive notifications continuously block a much-needed application despite all settings to enable its notifications (no battery optimization, run app in background, unlimited data). Literally every notification setting in the application and the system are enabled to permit the notifications, but as soon as adaptive notifications switch back on, I stop receiving them.
Is there any way to prevent Android from reenabling them?

How to use internal mic with external headphones?
I want to use the internal mic while using the external headphones at the same time.
I have done some research, and it looks like the advice from Use built-in mic instead of earphone mic on call was to use an app called Lesser Audio Switch.

I was wondering if there is an alternative app or technique that could be used to achieve this effect. I have a Google Pixel 8 if that makes any difference. Thanks in advance.

Shared Google Calendar, but contacts are now also shared
I shared my Google Calendar with my family member, and he also shared his with me. Now, however, all of our contacts are also shared with each other. I don't want our contacts shared. He has a lot (400+) and I don't want to see all of his contacts mixed in with mine.
Other solutions I have checked into don't seem to address this situation specifically. There has to be a setting somewhere that says 'don't share my contacts', but I can't find it.
I have a Samsung Galaxy A42 and my family member has a Samsung Galaxy A25.

How did you "share your calendars"? To me sound s more like you added your husband's Google account as secondary account on your phone.

menu>settings>Manage accounts>add account. I think this is how I added. And since you phrased it that way, perhaps this is what I did. But, this does not explain how/why the contacts are being shared, or how to break that link.  Thank you for your comment.

What you did was not sharing a Google calendar, instead you simply added a seconds Google Account to your Android device.
The seconds device of course then synced all calendar entries but as well all contacts als GMail messages.
You can see the categories sync is activated in Android settings of the account:
Menu -> Settings -> Manage accounts -> Select your husbend's Google account -> Synchronize Account -> For each sync category there is a switch for enabling/disabling sync.
Sharing only a calendar
Google provides a sync method that solely shares the calendar. This way is not available from the Google Calendar app, according to the Google Calendar sharing documentation it requires to use the web version of Google Calendar:

Share a calendar with specific people:
On your computer, open Google Calendar. You can’t share calendars from the Google Calendar app. On the left, find the “My calendars” section. To expand it, click the Down arrow Down arrow. Hover over the calendar you want to share, and click More More and then Settings and sharing.
Under “Share with specific people or groups,” click Add people and groups.
Add a person’s or Google group’s email address. Use the drop-down menu to adjust their permission settings. Learn more about access permissions.
Click Send. The recipient will need to click the emailed link to add
the calendar to their list.

YES! This is working as I want it to. Thank you so much. I see we were sharing everything Google. So I was able to drop that connection and share only the calendars. Thanks again.

@KathyKeil On Stackexchange you can say thank you by upvoting and accepting (the grey/green arrow below the up/downvote buttons. As this is an answer to your own question you should be able to do so even without having the necessary reputation score.

As of current versions, would any of these setups pass safetynet checks?
Would these pass?
OP3T + LineageOS + Kernel that doesn't show bootloader unlocked status?
and also
OP3T + LineageOS + Kernel that doesn't show bootloader unlocked status + Magisk?
I'm currently on Marshmallow and am considering upgrading to 7 (through lineage) but I want to make sure I can pass checks because some apps are a royal pain to use/install if I can't pass the check.
(I would likely not be using Xposed at this time, so I'll leave that out of the equation).

Main reason for safety net failing is SU/rooted phone. So if you plan to root phone safety net can't be passed, actually you can pass it with su hide or magisk but that is game of cat and mouse. Xposed itself isn't a problem I think but since it requires a root you see a connection there. ROM and kernel shouldn't make any problems with safety net.

That's not correct.  Safetynet trips for an unlocked bootloader.  Kernels can prevent this by lying about the bootloader state.

Well then you have answered your own question :)

I have not answered my own question because I still do not know if LineageOS passes safetynet provided you use a kernel that does not report the bootloader being unlocked.  It can still fail without that specific trip.

Oh, well then I think it's best to test it yourself or ask on xda one plus forums

That's not really helpful.  I asked here.  The XDA topics are too specialized.  Would I ask on the rom thread, kernel thread, device thread, etc...

Make a new thread in Q&A subforum for OP3T

I have been using my OnePlus 3T with LineageOS 14.1 without su and with a custom-built kernel for half a year now. SafetyNet passes, AndroidPay works.

Unable to connect phone to normal Wifi networks after using corporate WiFi
I use my office network which is a Corporate WiFi set-up secured with 802.1x (and requires me to use my company credentials - Username and Password). But when I'm back home and try to connect my home WiFi router which is protected by WPA/WPA2 PSK security (which requires just a password), I can't get it connected automatically (even if I have the network remembered).
All I can do to fix it currently is;

Restart my home router several times.
Restart my phone for 2-3 times.
Forget all remembered WiFi networks on phone.

and only after above steps it can connect, otherwise I get Authentication Problem as error if I try to connect. I'm on Android 4.2.1 (almost stock android, just some custom icons by vendor) device running on MediaTek chipset (MTK6589T), Micromax Canvas Magnus A117 to be specific.
While this same problem is with my other friends as well who use our company network at office in their phones (which are varied from Samsung, Sony, and even Nexus).
What can I do to avoid this daily hassle when I return home and connect home WiFi?

Is your router's network name the same as the one in the office? Something generic like "Netgear" or "WiFi" by any chance?

No, both networks have different SSIDs.

Are your WiFi passwords synching with Google maybe? You could have the list with "WorkWiFi" and that synchs, removing all the others. It's not likely, but I've had nothing but trouble with WiFi passwords on my devices, I lost ALL of them again yesterday for no apparent reason :(

Disable Google sync (leak wifi passwords). If you have rooted smartphone try wifipass application (check wifi pass) and wifi analyzer (diff wifi connection attributes)

Samsung Galaxy S4 turns off internet at night
On my friends S4 the internet connections (WiFi etc.) turn off automatically from 10pm and turns on again at 6am the following morning, so he gets no messages between those times.
Is there a way we can change it maybe?

Galaxy S4 has 'Blocking Mode' to turn off connections at specific times, you can set exceptions so allow calls from a few people or Gmail only notifications etc. This should do it.

Try the profile settings. He probably has set a "night"-profile which turns down the volume and activates the plane-mode. The profile settings can be found in the normal settings of your phone.

In your notification shader, look for the "Blocking mode" icon, tap and hold it. You can activate the blocking mode there, pick a time frame for when it is active (e. g. 10pm - 8 am) and select what should be disabled from incoming calls, notifications, alarms and the LED indicator.
You can also allow only calls from certain contacts to go through to you, which can be helpful for emergency situations.

Can I update a file via email
I'm looking for a way to update a file (override it if need be) on the SD Card from an email attachment with one click, sort of like a Batch file in windows.
We have 50 tablets at work and every now and then we need to update a price list file. Most of the users are not too bright and can't copy from the attachment and then navigate to the correct folder and then paste the file in.
I would like to know if there is any way to automate this like a batch file in windows, is it even possible.
All tablets are using 4.2.1 and are Asus TF300T and NOT Rooted. I usually email the updated file then have to spend 15 min with EACH person holding their hand to update it. Any help or direction to a thread with something similar would be very appreciative

TBH, it sounds like you want to replace your email solution with a Dropbox-like app (but not specifically Dropbox, unless you want the whole world to see your price list).

In default email client, and I believe most other email clients, once you clicked on the attachment, the file will be cached on the device, so it wouldn't need to be redownload (at least until the cache is full). Is there any reasons why you need to put it in a local folder?

Taking up Dan's suggestion: did you look into ownCloud? This would enable you to host the file(s) on your own server, or rent a space with your provider to run the service.

Hi all It needs to go into a local file so the guys can find it. If it was just to stay in the email program it would get lost with other email the tablet recieves

A cloud type server is not an option as they only get Wi-Fi for a limited time of the day, so I need it to be stored on the tablet (on the SD card preferably).
It would be something like a bat file on windows, just click on it and it would copy the PDF file that is in the same email as the .bat file and then paste it into the stored folder on either the SD card or if I have to, I can store all the PDF’s on the device’s internal storage.

Swapping touch digitizer from one Android phone to another
I have an IKALL K260 Android 6 phone with a faulty touch digitizer, a broken connector strap, and is irreparable, having IC SILEAD GSL1691. I want to replace that digitizer with Gionee F205's touch digitizer having IC Goodix 917D.
I have connected the pins in the same order, but it's not working. It (IC Goodix 617D) heats up and does not let the display glow. It seems like there is some driver-related issue, the phone may not have drivers for the new touch digitizer.
So, can anyone tell me, is it possible to add drivers through USB with a computer?

Drivers on Linux have to be compiled into the kernel or if the kernel supports modules a kernel module that was built for that specific kernel version.

Thanks for commenting

I figure out that IKALL K260 is a Unisoc device but Gionee F205 is an Mediatek device is it possible to flash phone with Mediatek firmware !

And what would you do with a phone that has a working digitizer but all the other components like display, sound, WiFi, cellular, gps, keys don't work because the drivers don't match the contained devices? What you would need is building/compiling a new kernel so that it contains all the drivers for the hardware components in your phone.

Since @Robert did not make it an answer, to complete off the question.  You cant just add a driver like you can on windows.  At least for the hardware integrated into the phone, the drivers are also integrated into the kernel.  Without looking at the two devices, it is unlikely that they would have the same pinout.
Seriously, Android 6 is way too old, maybe your money is better spent buying a newer second hand phone.

I know of course Pinyin is almost never written out unless for educational purposes - and these are exactly those I opt for.
Maybe there's a downloadable in-app feature or any other add-on I don't know. But currently, I have to insert everything character by character and fiddle with the right tone marks by pressing a character long and choosing between the options which pop up - which is not a solution in the long run.
Since I have seen Chinese people write Pinyin fast, I'm pretty sure such a feature exists on Chinese phones, but I want it on my phone as well.

Does Macrodroid search ALL embedded folders in a directory or only the master?
I followed Reddy Lutonadio's instructions on Auto-delete certain file extensions on my phone?
My unwanted files were TXT files of the same name that tag along with downloads in my email downloads and NFO files.  Wrote the script subbing my parameters and nothing happened to the NFOs in nested folders.  Help Please.  Is there a setting or option I am missing?
My phone is NOT rooted.

Is there a way to find reason of Android reboot?
I've OnePlus 9 Pro with Android 13. The phone is rooted and has a custom ROM, but my issue isn't common for that ROM. The Phone generally works well, however at least once or twice a day it suffers random reboots. Sometimes it's during a call, sometimes when browsing the internet, and sometimes I spot the phone rebooting while lying on the desk, so the issue is not related to a particular task.
I haven't updated my ROM for a while, I'll do it today, however, the problem did persist through updates earlier. It has that annoying habit since I've installed crDroid, it didn't have so on stock rooted firmware. I've flashed it strictly by the manual of ROM developers - from stock firmware to crDroid, all updates were installed after upgrading firmware, as it was mentioned by the devs of ROM, so I think that it must be one of randomly crashing apps.
I know about logcat, but it definitely has too many lines to find anything out of it (another thing that I'm not sure about is if it persists through a reboot).
So, I was wondering, if it's possible, how to find out a particular reason for such a random reboot. Is there any event log in Android, or someone could recommend such an app? Is there any other source of knowledge in Android or a Magisk module to log such things?
