What will happen if I flash a custom rom for GT-I9082 on a GT-I9060c/m/i?
I have a Samsung Galaxy Grand Neo Plus/DUOS (GT-I9060C) and I would like to know what will happen if I FLASH A Custom Rom for the Galaxy Grand Neo DUOS (GT-I9082) Onto my phone (GT-I9060C)
Will it be Hard-Bricked,Soft Bricked or will it work fine
Custom ROM description : Lineage OS (Android 7.1)
Linux 3.0
Supports dual sim
Current rom: Rooted Stock rom 4.4.4 kitkat SuperSU  Pro running TWRP 3.0 For GT-I9060I (idk how gt-i9060i twrp recovery worked on the gt-i9060c
With AKAS security software (idk what that is)

Hmm So if i did flashed the rom and its soft bricked (repairable) will i still be able to use DownLoad Mode because i heard some people said that it will hard brick your phone (unrepairable) if you install roms that wasnt met for your phone. Also im on GT-I9060C not on GT-I9060I because i9060i doesnt have a magnetic sensor
Heres some description about my phone:

Possible duplicate of Can I install a ROM made for a different device?

The similarities of the 2 devices are mostly only in their name. Grand Duos (i9082) is out Jan 2013 and uses a Broadcom BCM28155 SoC, while Grand Neo Plus Duos (i9060i) along with its family are out circa 2015 and use a Broadcom BCM23550 SoC.
Recovery will reject ROMs made for a different device, and even if you manage to flash it in, it won't boot due to the hardware difference (soft-brick in your words).

Where should I place iptables update on Android at boot time?
I need to write specific values in the routing system using the iptables command for Android.
The overall idea is that the user can navigate only using the provided DNS configuration.
I've tried to invoke them inside an script through the init.rc, but the script is never called:
service update_iptables /system/bin/update_iptables.sh
    start update_iptables

When I plug the phone to the computer and execute the following sequence, it works without problems:
adb root
adb remount
adb shell /system/bin/update_iptables.sh

Obviously, when restarting, this configuration is lost. That's why I need to run this as part of the start boot sequence.
Any advice on where in init.rc (or any other configuration file) can I place the script?

Any file that resides under / is reverted during boot. Your best bet would be to create a script that does your bidding, and place it under /system/etc/init.d. Note that the phone's kernel needs to support init.d, else this won't work.

Root Samsung Galaxy J Max ( SM-T285YD)
How to root Samsung Galaxy J Max ( SM-T285YD) Tablet and install TWRP Recovery?
Till now i have already tried apps like KingRoot, Towellroot, RootGenius and all of failed rooting this device.

Rooting and installing TWRP are different things. You'd better start with latter.

Yeah I know that . I am asking  help for both issues.

So you should create different questions for each.

SM-T285YD is Galaxy Tab 2 (2016) ?

@esQmo Thinking of a similar thing... The T285(Y) model name is tied to Tab A 7.0 (2016), and these 2 devices look markedly similar (J Max does have a gold accent).

@esQmo No its Galaxy J Max (2016).

If your device is 5.0 and higher you will need to perform oem unlocking. Otherwise you will have a brick
YOUR WARRENTLY IS NOW VOID
Some Samsung devices doesnt work with rooting tools installed on the device so you will need to install KingoRoot/KingRoot.exe on your computer, open it and read instructions..
Rooting your device with kingo root is easier because hardly any setup it required but if you are into SuperSU, kingroot is recommended
Just press that root button and wait.. make sure you have a good amount of battery..
Now installing TWRP. Your device must support TWRP if theres no twrp for your device DO NOT FLASH TWRP THAT WASNT MEANT FOR YOUR DEVICE!!!
Download Samsung Drivers (Your device might install it for you, if not install it from the web)
Download Samsung ODIN v3
Download your twrp recovery in a format of TAR.MD5
Select AP and select your recovery
Put your tab into download mode (Power+VolDown+Home)
Connect it with Usb Cable
Once it said Added! Press START.
Before you do that just make sure F.Reset Time is ticked and reboot also because i dont think ur tab doesnt have a removable battery.
Once it said PASS your done just shut down your tab and boot into recovery (VolUp+Power+Home)
And here you go! You are running TWRP
Also for more help for your device go to this site XDA-DEVELOPERS.COM

This method won't work on Samsung Galaxy J Max. So far none of the apps available on the internet has able to root this phone both android and pc apps fail. Tried ODIN to but root failed and my phone stucked in downloading updates luckily i had an official firmware and i recovered from it. I think currently rooting is not possible for this phone till developer find it. Don't try to use any unofficial firmware either you can damage your phone i tried every suggestions and methods available in the internet but all have failed. I think we have to wait till developers find vulnerability in this de

Lenovo A2010-a keyboard
I updated my lenovo A2010-a system and I can't unlock it cause my password is a pass code type, and the keyboard isn't working.
I already tried restarting my phone many times.
What should i do?

Have you tried the following fixes:

Fix 1: Restart the keyboard

Restarting the keyboard can be very effective in solving the problem. Many have found this to be helpful.

Go to the Settings menu of the device
Scroll down to the Apps section and Tap on Application Manager
Swipe to go to the “All” tab
Now look for the app Android Keyboard and tap on it
Now tap on Force Stop to stop the keyboard

Exit out of the Settings menu and go back to using the keyboard and check if it works. If you happen to use a third party keyboard or if the device manufacturer has installed its own keyboard then you should look for the keyboard that is in use.

Fix 2: Clear Cache and Data for Keyboard

Clearing the cache and data of an application allows you to clear files that can be possibly corrupted or which may be creating problems because of bugs.
While deleting the cache files does not delete any important information, you will lose your personal settings when you delete the data files from any app.
If you had made specific changes to the keyboard, you will lose those settings. You will have to go back into the keyboard settings and make the changes once again.

Go to the Settings menu of your device
Tap on Application Manager which is under the apps section
Swipe to the tab which includes “All” apps
Now look for the keyboard app. It can be Android Keyboard or the keyboard that you are using if you have installed a third-party      keyboard or if you have the manufacturer skin on top of the stock       Android.
Tap on the keyboard app
Tap on Clear Cache
Now tap on Clear Data
Tap on OK to confirm.

Fix 3:  Clear Cache and Data Files for Dictionary App

The dictionary app is closely linked with the keyboard app.
If for any reason you get the “unfortunately keyboard has stopped” error, there is a chance that it may be because of corrupt files in the dictionary app.
Deleting these files can be helpful in solving the problem.

Go to the Settings menu of your device
Tap on Applications Manager
Swipe to go to the “All” tab
Scroll and look for Dictionary app and tap on it
Tap on Clear Cache
Tap on Clear Data
Tap on OK to confirm

Once the cache and data files have been deleted, check if the problem has been fixed.

Fix 4: Install Updates for Google Keyboard
You can try fixing this issue by installing updates for Google keyboard. For that, navigate to play store on your android phone and look for the updates. Alternatively download the updated Google keyboard from google play store via your PC (Apk leecher website - can directly download the apk from Google play servers)

Fix Android keyboard stopped working

Hello sir, thank you for your suggestion. But, i cant unlock my phone cause i need the keyboard to enter my password.
What if i use trusted devices? how do i do that?

Absolutely, you can use "trusted devices" , do you have any devices (e.g smartwatch or smartphone) you had allowed to use that feature?

Yup! I added my friends phone as a trusted device.

Great! Now you need his device to be in close range.  The lock screen security on your  device gets disabled when you are connected to a trusted via Bluetooth (your friend's device).

Lemmie know if this works, if you didn't have Bluetooth enabled, if you didn't have it active and cant access it from lockscreen, I guess you could try a workaround by installing Bluetooth toggle app, via PC using a simpler tool (android app installer or adb)

Motorola DROID Maxx In Reboot Cycle
My Motorola DROID Maxx, for some unknown reason, is constantly restarting. I tried to put it into safe mode, but to do that it needs to restart and it continues to go through this loop. I had this issue only recently, then I wiped it clean. I put back on my phone the apps I had before (list of them below) and updated some of those that came with it. While I was trying to do that, it wouldn't connect to wifi. I tried to turn it on but it keeps turning off (quite the rebellious). Then it randomly started doing the restarting thing again. I have tried safe mode, but it ignores it. I have tried recovery mode but so far only managed to get into it once. I hit the power button by accident and left the recovery mode.
Later, I managed to get into recovery mode and selected recovery. I managed to get to the menu and rebooted the system. It was no longer in the cycle and was now only shutting down without warning (no vibrations or anything) every time I start it up. At one point, I couldn't start it back up, so I put it on the charger and managed to get it. Then I put it into safe mode and it started the cycle again along with occasionally completely shutting down. After it shuts down it doesn't start up until I start it up.
Any ideas as of why it is doing this? Also, does anyone have a solution?

Here are the apps I have added (to the best that I can remember):

Facebook
Messenger
Google Sheets
Google Docs
Libib (had this before I wiped it, forgot to add it afterwards, so this isn't the issue)
Covenant Eyes (my dad put it on my phone, I don't know if he actually put it on my phone after the wiping, so this may not be the issue)
YouVersion (a Bible App, this is one of the last ones I put on there)

If I put anything else on my phone, I don't remember at the moment. Some basic things were updated (Google apps, camera, gallery, etc.)

Some additional information about my Droid (I don't know if this is of any help):
Model: XT1080 FCC
ID: IHDT56PE2
Type: M0DBA

Unfortunately, sounds like a hardware issue to me. Have you tried flashing the stock firmware?

What do you mean by "flashing the firmware"? BTW, my phone is no longer on the reboot cycle but it still is tempermental with the wifi. Same issues as stated in question. It sometimes decides to work while other times it turns off the wifi and I end up using data.

Flashing the firmware is essentially the same thing as doing a clean install of the OS on your phone. It would be similar to reinstalling windows on an empty hard drive for a computer. There could be a corrupted file on your current install or it could be a hardware issue(which we can't help you with unfortunately) at the very least flashing will eliminate the possibility of it being a corrupt file/software issue

Bluetooth keyboard glitches when pressing space
I have a Samsung Galaxy Tab S2, running Marshmallow.  For some reason, when I use my bluetooth keyboard, I get an intermittent error when pressing space (or any punctuation).  As near as I can tell, when it does happen, it is when I press space after a mispelled word (or one which is not in the dictionary) or a number.  When it happens, it moves the cursor to the beginning of the mispelled word.
For example, if I type '2017', then hit space, the cursor will jump to the beginning, like so '|2017'.  As you can imagine, this is incredibly annoying.  When typing my email address, it jumps 3 backwards times.
I know this is incredibly specific, so there might not be an answer.  If I remember correctly, it may have started happening when I added another language to the on screen keyboard, but I've disabled that and the problem remains.
Any suggestions?

yes please help with this - same issue for me!

yes please help with this - same issue for me!  is it possible to turn autocorrect off just for bluetooth keyboard?

In Android 6, the CPU temperature showing 50-55c when I just using browser with Wifi?
I am just using UC Browser with Wifi but after some minutes the temperature reaches to 50-55c? What is the probledm?

That's completely normal operating temperature for a CPU.  Most function perfectly fine up to at least 90° C, though on a phone will typically throttle before that to ensure that the phone as a whole does not get too hot.  Not too much more to be said without knowing how this compares to other browsers on your device (UC Browser might just be less efficient) or what you're browsing (maybe the site is poorly coded and has a lot of intensive JavaScript operations).

I would add that the temperature is so high because there is no real heat dissipation happening on a smart phone (heat pipes are in place in some phones but they just spread the heat a little). The chips are also incredibly tiny and the temperature readings are usually just bursts of high temps.

I don't think that temperatures get to 90°C without harm that is too high I think

@ЈеднорукиКрстивоје SoCs can mostly stand that without a sweat; on-board memory, however, will take hits at temperatures upwards of 80°C-ish, with stability and data integrity gradually affected. That's quite unlikely on phones, but possible for memory-intense devices such as graphics cards (PC).

Looking to somehow get control of my LG Optimus G with broken screen..
I dropped my phone the other day, and the screen cracked rendering it completely useless as it made the digitizer break. I have no touch control of my phone whatsoever, I reset it like an idiot to see if maybe the digitizer will decide to work again (so its no longer connected to wifi at the moment). I'm wondering if there is any way whatsoever to control this phone from my PC, without USB debugging enabled (or, if there is a way to enable USB debugging from an unrooted device). I do not plan on replacing the screen, as the phone is a little outdated now. Any suggestion is appreciated highly, I just simply wanna be able to get some sort of use out of this phone before letting it go for $20 on kijiji.

Welcome to Android Enthusiasts! Have you already checked with our broken-screen tag-wiki? Plenty of useful hints there.

I recommend you take it to a place where they fix phones. They can fix the screen for you. Depending on who you go with, the prices will vary. Other than that, I doubt there will be any other way.

Stolen phone - does Android Device Manager's lock override the thief's password?
I'm currently trying it on another phone and it seems that as long as I have a pattern lock set up, the ADM lock screen shows up but the old pattern is requested instead of the remotely set password. The stolen phone had a simple swipe lock (Android 5.1) - if the thief set up a pattern/pin in the meanwhile is the ADM lock basically useless?

Okay, in my case the thief can definitely still use the phone - he receives WhatsApp messages and can read them eventhough I've set up the remote lock over 50 times. This is absolutely revolting - an utterly useless feature. I can guarantee he's not circumventing it another way - if they were even at the least bit technically savvy they would have wiped the phone, switched the Google account or at least disabled ADM long ago.

There might be a case if the Thief has formatted your phone to factory settings. Then in that case, ADM will be useless. Also, Hard resetting a phone is so easy, He was a thief, He would have done that till now...

Blocking Websites/Apps on Samsung s6 [G920VVRS4CQA3]
After researching all day how to root my specific build number of the Samsung Galaxy s6, a G920VVRS4CQA3, it seems it cannot be done (safely, at least) due to the locked bootloader that comes with the Verizon and AT&T models. I looked into all kinds of different methods but to no avail. (I wanted to root the phone in order to edit the host file and block webpages.)
So, I wanted to ask - what is the best alternative to blocking SPECIFIC apps and SPECIFIC webpages on the android device? I need an app or method that doesn't scream "this app/webpage is blocked due to parental control." I'd like something more discrete that would just lead to a message claiming "server not found" or something of the sort. I am not looking to block ads or filter out an entire category of the internet, I just need a way to block specific websites and apps on the playstore that cannot be easily tampered with. Something with a passcode.
Alternatively, if you have been able to root the G920VVRS4CQA3, I'd greatly appreciate knowing how to went about doing it.
Thanks

by "blocking specific apps", do you mean to forbid internet access for those particular apps while the rest continue to have internet. For this you need a firewall application (eg NoRoot firewall from playstore). If you wish to block some websites (or IP addresses) , you might need to run your own DNS Server  on your device and add rules for the DNS Server (give an IP for a set host or block certain hosts) not entirely sure if root is a requirement though

Google app "Keep": only show unchecked (unarchived) list items when exporting?
I use Keep for maintaining a reusable shopping list. (Shared with family on other devices). I mark the item with a checkbox when bought for later use.
But if I want to send the list (eg via email) surprisingly it exports all items in the list, both checked (archived) and unchecked! So when I export it, I have to manually delete each of the checked rows from the email before sending. Is there a way around this?

Yu yureka Recovery
I have yu yureka phone on which I tried to unlock the bootloader and flash cwm recovery. As the process continued and at last the window showed ' finished'. I then tried to boot into recovery mode by pressing all hardware keys simultaneously but it didn't opened recovery and the phone started to homescreen. I need to know whether recovery is installed properly or not. I don't want to boot into the recovery mode because last time it did so and the phone was in bootloop so is there any way to know if the recovery is installed properly or not without rebooting it in recovery mode.
Thanks. Please help.

are the apps being uninstalled during OS update?
I haven't updated my Nexus 5X OS version for a long time already, due to the fact that I'm really afraid that something might go wrong with the state of some of my apps.
For example, my WhatsApp history goes back to 2011. The folder size is ~5GB and holds more than 29,000 files. A few times before the app produced a warning shich stated that its state is corrupted for some reason ("something went wrong") and that a restore is needed -- each time it took hours, and almost never succeeded immediately (I had to re-install and change some backup file names).
So, my question is basically -- what are the steps of the Android OS update installation process? Does all the apps being uninstalled, then the new version of the OS is being installed, and then the apps are being installed again? Or is there some "intermediate state" for the apps, which can provide an option for the apps not to be uninstalled in the first place?

If you do a normal system update (no restore or something like that) your apps are not uninstalled. The system doesn't really do anything with your apps at all until it finished the system update. Then the system will recompile all apps (The 'android is optimizing apps' dialog) in order to make them run faster. This should not interfere in any way with your data.
I do not know about your specific problem with WhatsApp or if a system update could cause your error but your data will not be touched by the system during the update. This means if something breaks whatsapp your data will still exist in order to restore your history.
Btw. what android version are you running? With android 7 the recompile step will partially change (to the good).

From the "app perspective", it's the same as an app update (through Google PlayStore for instance), or the same as an uninstall and re-install with recovery (due to the fact that the data is untouched, as you mentioned)? I'm asking, because I'm not afraid for my data, I've backed it up, I'm afraid for the "fragile" state of the WhatsApp app - I just don't want it to start some type of basic recovery and fail, due to my "abusive" usage of the app.

From an "app perspective" it will be (more or less) the same as an usual app update (with PlayStore).

Playing web games that require arrow keys without using a physical keyboard
I would like to play some web games like Unikong using my tablet. But the problem is, they require a keyboard, or specifically, the arrow keys in order to play.
I know I can connect a mouse and/or keyboard via OTG and play, but I don't always have access to them.
I have Hacker's keyboard (has arrow keys) but the game registers my arrow key inputs only sometimes at irregular intervals. This happens not only for Unikong, but other similar games too (I remember creating a small JS canvas game myself that it works fine on the PC, but not with hacker's keyboards' arrow keys). Here is a GIF from where you can see the problem (Sorry for the low quality 5 FPS GIF):

Note that this happens on some games only. For example, this problem does not exist with Chrome's T-Rex game.
So, how do I play web games that require the use of arrow keys using my Android tablet without a physical keyboard?
I'm running a rooted Android KitKat 4.4.2

Game Pad seems to meet your needs looking at the play store video ( I don't play games so not sure if that's what you want)

@beeshyams Unfortunately, for some reason, Game Pad's permanent notification doesn't work. I can't see any notification even though I've enabled its 'Permanent Notification' setting. So, I can't open the keyboard to test it.

Why I get the foolowing "Settings isn't responding. ... close it", when i turn Wifi on? (even in Safe Mode!) /Android 501 & Sams S4
Android 5.0.1 /Samsung S4, Not rooted.
Why I get the following message dialog "Settings isn't responding. Do you want to close it?", every time when i turn Wifi on? (even when phone is started in Safe Mode! ...ie without any external app).
In fact EVERYTIME I navigate to Settings and push the wifi to ON itself, it gets stuck there for a minute and the following dialog pops up, with 2 choices: "Wait" and "Close". If closed is pressed then Settings closes and wifi never gets ON. If Wait is pressed then it hangs for another minute and same dialog pops up. Again, if Wait is pressed and after another minute ONLY THEN settings proceeds and turns finally the wifi ON. And proceeds working normally. SOMETIMES: an extra step of dialog appears making the total of appearances at the most 4 times. But even then it finally turns ON and settings is anew functional.
Needless to say while Settings is trying to turn wifi ON, no other function in Settings can be selected and processed...The whole process of Settings is frozen.
I searched internet already and haven't found (tried MANY of proposed) a solution, even though a lot of people experience similar problems with turning wifi on and getting stuck - regardless of type of phone and android version.
It also gets stuck even if i try to ON the wifi directly from the top task bar by pressing the (green) button - it gets stuck in faded green color without turning wifi ON.
Please, has this problem been solved reliably by anyone? All info is much appreciated.

Tried backing up and flashing a factory firmware? Sounds like a near-dead WiFi module to me, probably want to verify that.

Try to make factory reset.

Thank you both "Andy Yan" and "Suncatcher" for the suggestion. No, I haven't flash a new firmware/factory reset. I would very much try to avoid the hassle of it. In fact IF I go through that, I consider rooting also and maybe flashing a custom firmware too. Actually the Wifi does work - even after this 3-4 minute delay, so for the moment I go by with that. Please could you elaborate on how to verify the "near-dead wifi module" ...or maybe you mean if problem persists after flashing fact firmware that would lead to prove the module(hardware problem) is responsible?

Yes, the compatibility of the apps.  I tried ADI for Google Pixel launcher, it was early access invite/beta.  Could not gain root permission.  This is why I asked. @AndyYan

Android mount external sdcard obb to internal SD card succeed
(I posted this question on Stack Overflow before(https://stackoverflow.com/questions/42738392/android-mount-obb-to-external-sd-card-failed), then I found here may be a better place to post this question.)
I want to move a game's obb(1GB) to SD card.
Copied the obb file to SD card, and symbolic link by:
su
ln -sf /storage/sdcard1/Android/obb/com.game /sdcard/Android/obb/com.game

but failed with "function not implemented".
I googled it, and got "some filesystem doesn't support symbolic link".
So I tried to use mount by command:
su
mount -o bind /storage/sdcard1/Android/obb/com.game /sdcard/Android/obb/com.game

but I found only root can see the files in the folder.
Then I do:
cd /system/bin/
chmod 4777 ./toolbox #make anyone can use mount(in toolbox)
su u0_aXXX #the game's uid
mount -o bind /storage/sdcard1/Android/obb/com.game /sdcard/Android/obb/com.game
ls -l /sdcard/Android/obb/com.game
$ -rwxrwx--- u0_aXXX sdcard_r com.game.obb

But when I
cat /sdcard/Android/obb/com.game/com.game.obb
$ cat: /sdcard/…ame.obb permission denied

I'm using android5, any solution?
Thanks.

(If you're finding how to move obb to external sdcard and mount it back to internal, here's the right place!)
Finally I found the solution of this question by myself!
The app can't access the obb by itself, it requires media_rw to access it.
Found by lsof:
sdcard 340 media_rw 15 ??? ??? ??? ???
/data/media/obb/com.game/com.game.obb
sdcard 340 media_rw 17 ??? ??? ??? ???
/data/media/obb/com.game/com.game.obb
com.game 26335 u0_a266 36 ??? ??? ??? ???
/storage/emulated/0/Android/obb/com.game/com.game.obb
com.game 26335 u0_a266 37 ??? ??? ??? ???
/storage/emulated/0/Android/obb/com.game/com.game.obb

So I have to mount the external sdcard folder to two places and each has to have its right owner:
owner    folder
u0_a266  /storage/emulated/legacy/Android/obb/com.game
media_rw /data/media/obb/com.game

But if I mount /storage/sdcard1/Android/obb/com.game to those two places, it will become:
owner    folder
u0_a266  /storage/emulated/legacy/Android/obb/com.game
u0_a266  /data/media/obb/com.game

Then I found if I do:
mount -o bind /storage/sdcard1/Android/obb/com.game /storage/emulated/legacy/Android/obb/com.game
mount -o bind /mnt/media_rw/sdcard1/Android/obb/com.game /data/media/obb/com.game

I found this works fine, because the mount command's source and destination is their original owner.
The app can run very well!

How to close Google account on the phone
I let my friend borrow my Android phone. She never returned the phone and she is still using my account. Please, help me.

Sign in to your account here and delete it like that:

More info on deletion you can find in help article.
After the successful deletion your account will be signed out from the phone as well and your friend will lose the opportunity to use it.
If you want not to delete the account per se, but to delete it from phone (i.e. log out) without physical access to the phone, you can try to use Device Activity tab and revoke access there:

Does selecting "delete thumbnails" actually delete "save as" images from your phone?I
I just started using "save as" on Firefox for Android and I saved a lot of important images that meant a lot to me. Then unrelatedly my phone started acting weird, it became very slow and laggy. So I installed ccleaner and since it couldn't do much for my healthy and not crammed full system I simply selected Delete thumbnails and let the app do its work. Minutes later looking for my photos they only came up in Download history and when touched it says the file is gone. Did CCleaner "delete thumbnails" actually delete all my recently downloaded jpg??? If not, where are they? I've been in Gallery, searched files by name, everything. I don't use an external memory card and I'm using a Samsung J7.

Since you use Save as instead of Save target as, the image actually getting saved is the view created by firefox which is  of very low size that is less than 50kb.
So, some cleaner apps consider images with less than some size (say 60/100kb) as thumbnail and remove it.
Here, the same happened to you.
Next time, consider save link as or open image -> (and  when full image is loaded) Save image

Thanks for answering Sagar, your answer is helpful and informative. I have to add that this sucks. The only reason I'm using my phone internet for serious things is because my computer magically broke 4 days ago and I have no idea how to fix it. Hopefully the guys at Tom's Hardware will be as helpful as you are.

why can't we format bootloader code
Some phones had locked bootloader.  As far i understand bootloader is a piece of code responsible to load the os. but that is still in the harddisk right?
so why can't we delete that code and put our own.

Related: https://android.stackexchange.com/a/205552/218526

First, the definition of a bootloader (as described by Technopedia):

A boot loader primarily manages and executes the boot sequence of a
  computer system. A boot loader program is typically started after the
  computer have finished performing the initial power. It fetches the OS
  kernel from the hard disk or any specified boot device within the boot
  sequence, into the main memory. A boot loader is associated with only
  a single operating system. An operating system can also have multiple
  boot loader programs classified as primary and secondary boot loaders,
  where a secondary boot loader might be larger and more capable than
  the primary boot loader.

On samsung devices you can enter into download mode and plug your phone into a pc and open up Samsung Odin 3 and flash a bootloader by selecting BL and the file
Also flashing bootloaders is EXTREAMLY RISKY. Flashing the worng or incompatable bootloader is worst than flasing a boot.img that wasnt meant for your device. It will result in A hard brick and its very rare to recover from that unless you have a Programmer JIG/JTAG
Also flashing items in a locked bootloader is very dangerous because theres 100% cHance of Bricking your device if you flash a custom item..
And a bootloader is programmed into a ROM chip it cannot be easily changed fomating. Its better for you to not interfare with your bootloader unless you want to unlock it and root or flash things to your device.. Custom roms are made with these 2 CRITICAL IMGs BOOT.IMG SYSTEM.IMG
Also theres no need to make a custom bootloader because almost every device has the same bootloader type but differ from code and compatibility

Most of the text is a copy-and-paste from Technopida. Anyway it does not answer the question.

When you make use of content that is not yours you need to indicate that and give the original author credit for their work.

Thanks @eldarerathis for pointers. Hmm i want that hard brick.

Sorry about that.. im only 2 days old on this forum :3

Whats ASKS Security Software and Device Protection Manager?
My phone updated and when i check about device i got something i never know about that ASKS Security Software thing and a new appication named Device Protection Manager with no accessable interface

So what are these and what does it do?
And is it recommended to remove these features because so far i think its useless

The phrase 'Device Protection Manager' is an uncommon name for this software. Usually it is truncated to 'device protection'.  I found a link that may help you.
https://www.greenbot.com/article/2904397/everything-you-need-to-know-about-device-protection-in-android-51.html
Basically, it is anti-theft software, plus...  You could have 3rd party software that is doing the same thing, so you may want to scour your device for such and eliminate all but one. Choose one that doesn't drain your battery so much.

How to find the public name of a contact on Viber?
I have added a new viber contact, but it (correctly) displays the contact with the name I've used in my contact book. Nevertheless, I want to view my contact's "public" name, the one that my contact has chosen to "advertise". It's the username you set up when creating a new viber account. How can I see this?
My contact has been able to see my "public" name, I assume before saving my phone number in their own contact book, so it is definitely advertised.

It goes when you delete the contact off your local contact list and then you intend to add it thru your Viber(tested on iOS and Android).
How I did it:

Fount a contact number that I wanted to see his/her name
Remover it off my local contact list
Opened Viber and Navigated to More, followed by Add Contact
Entered the contact number and pressed Done (on iOS)
Please note that it does not add the contact, nor it notifies the recipient anyhow of the resonance of it's public name.

Yes
Secure JTAG explains

Disabled JTAG: This mode provides maximum security. All security-sensitive JTAG features are permanently blocked, preventing any debug.....

I do wonder how many still uses JTAG nowadays... It's already a tedious job to tear the phone down to where you can see the contact at all.

Is it possible to crack encrypted device?
I have device powered by Qualcomm MSM8974AC Snapdragon 801 cpu and running Cyanogenmod 13 (6.0.1 android) rom with unlocked bootloader and TWRP (3.0) recovery.
ROM has security patch level December 2016. Device is encrypted by FDE (Full-disk encryption) and using same PIN for lock-screen and booting.
Let's say attacker has full psyhical access to this device. The point of attack is decrypt data. Attacker has unlimited tries of entering password:
devicepolicy/java/com/android/server/devicepolicy/DevicePolicyManagerService.java:

DEF_MAXIMUM_FAILED_PASSWORDS_FOR_WIPE = 0

Based on that article if am understanding correctly the only possible way is exploiting TrustZone or Keymaster vulnerability and then just bruteforce psyhical dump on powerful machine.
But thats seems like got patched in January 2016 and May 2016 security bulletin (CVE-2015-6639
CVE-2015-6647 CVE-2016-2431 CVE-2016-2432)
So the question is it still possible without OEM help of course?

Most encryption protocol creators are paid by large security agencies to install backdoors, This allows the security agencies quick decryption without needing a powerful computer at all.. It is entirely possible that someone determined and well educated enough could stumble upon these backdoors and hypothetically gain access to any similar encryption from the same source.  I saw somewhere that our information on technology doubles every year, therefore in 20 years our information on technology could be more than 1 million times more than today and one year later 2 Million, never impossible.

@Zillinium it is entirely possible to do and has been acheived before. Ebaloff could you please provide your device manufacutor, model number, and if the device has usb debugging enabled, if you know, as this can help us, further help you with the specific device.

Also, i have a device that sound similar to yours but with a locked boot loader and stock recovery, are you using a Samsung with model number SM-S120VL?

Where are the TEE's keys stored and under which conditions are they reset?
Context: full-disk encryption in Android 6.0, specifically key derivation and storage.
I have a device running Android 6.0 with full disk encryption. I need to make a backup of the device, wipe the device, use it in the wiped state for a little bit, then restore from the backup.
I am running a custom recovery (TWRP), but unfortunately it cannot make a nandroid backup of /data because I guess it is very confused by the fact that /data is encrypted.
I was going to make a backup by just running "dd if=/dev/mmcblk0 of=/sdcard/image.img ..." in recovery in order to make a byte-level copy of the entire internal storage, with the intention of later restoring it by doing the same in reverse.
However, I am afraid that the hardware-bound key, which is stored in the TEE and used to encrypt the disk encryption key, is stored outside /dev/mmcblk0 and will be deleted when I perform a wipe. Thus, even though I'll succeed in restoring the image, Android will no longer be able to derive the same encryption key and thus will fail to decrypt my data.
Thus, my questions are:

is this correct?
if so, what are my options? if the key is actually wiped, I understand that it wouldn't make any sense for it to be possible to backup and restore it. However, perhaps there's a more roundabout way to wipe the device of my private information without deleting the TEE key?

How can I remove the "Install Google Play Games" prompt in apps?

I uninstalled the Google Play Games app on my phone to get rid of the other annoying prompt, but now I'm left with this one. Is it possible to remove the prompt shown above?

Lucky Patcher might be a solution

It's really frustrating to see that pop-up every time we play a game.
There's a solution if You've a rooted phone with Xposed installed in it.
It's a Xposed module which will stop that pop-up.
Be careful if not rooted.
Link - No Play Games - Xposed Module

Worked like a charm!

No, some games as well as some apps need the Google Play Games and Google Play Services' latest version. So it may ask you to update or use to authenticate.
The entire data of the game is stored in your mobile and Google server. The game maker's server didn't store any score or data. So it needs you to install Play Services not only for this but also to use some API calls to your account info.
You cannot remove it.

What I found odd was that I did something similar in Bluestacks (disabled Google Play Games instead of uninstalling it) and it removed the prompt. But it doesn't seem to work on my phone.

Both are different. There is many difference in bs and mobile.

I went into Androud Notifucations menu and dusabled notifications from the Google Play Store and that did the trick for me.

Not all apps depend on Google Play installation, despite asking for it. If I press Cancel when the prompt pops up, the game still loads and I'm able to play. But I can't get rid of the pop-up. It disappeared after a long while of ignoring it on other apps, but this new game just keeps asking for it. It also loads and I'm able to play.

The question is not about how to proceed loading your game despite that prompt. Instead, it asks "Is it possible to remove the prompt shown above?" Your answer hasn't addressed that part yet.

Tell the game developer to correct his sign in algorithm. If the game prompts for Play Games install, the developer set it to prompt for it. It is an extra command to give to let you see this prompt.

Google Play Games isn't just for sign-in. Games might need it for other functionality, so for any given game it might be very expensive for the developer to replace that functionality.

Every developer interested in audience and using Play Games should have a fall back function to work without it.

Remix OS Android Kernel Upgrade
I have recently Installed Remix OS on my pc. I found out that the linux kernel version on this version of Remix OS is 4.4.3 which doesnot support dual band wifi. How can I upgrade the linux kernel ?

Are you sure it's related? My Ubuntu machine runs 4.4.x kernel and detects AC WiFi just fine.

Upgrading kernel (major version) in Android is far not as easy as on proper Linux distros, usually only comes with an upgrade in the OS itself. Additionally, from what I've seen in the Android-x86 Google Groups discussion, 4.4 is by far the latest "stable" version for Ax86, while newer ones like 4.8 and 4.10 are still experimental.

I have Intel 3168. Which is not recognized....

How can I get old Android updates again after a hard reset?
I have an AT&T HTC that was running Marshmallow 6.0.1 and Sense 7. That's the last update my phone will ever get since it's an older model. I factory reset it to wipe it clean, which returned the software to Lollipop 5.0.2 and Sense 6. I've checked for updates in the settings and it tells me it's up to date even though it's not. Do I just need to wait a few days to get the update notifications? Or do I have to take it to AT&T and have them update it? Or do I have to flash marshmallow myself?
Model HTC Desire Eye
Build 2.09.502.3

It's unlikely that a factory reset can reset OS version. Can't help but wonder what you did prior to that. Anyway, I do recommend manual flashing.

Maybe it didn't, but I do know the interface doesn't look the same and I can't find certain apps in the Play Store because its downgraded. Do I have to root the phone before I flash it? I would rather not go through the rooting process...

Interface downgrade is possible, since HTC moved quite a bit of Sense apps to Play Store (even including the most central part, Blinkfeed!). Get them from Play if that's all you want. On the other hand, flashing does not require root, but does involve getting drivers right and finding a proper firmware, and for amateurs those troubles aren't exactly less than rooting.

Is there anyway you help me with flashing it? I really dislike the old interface. I've searched up and down and finding the right tools and firmware for my phone is pretty confusing to me.

By "interface" do you only mean the homescreen (launcher) or anything else? To help you with flashing a lot of details have to be provided, enough to be made into another question (which could be duplicate anyway).

It's biggest noticeable change is the lock screen. It shows my notifications right in the middle in big white boxes. And since the power saver option is always on, there's always a white box in the middle of my screen. Before I reset it back to factory, notifications would just display a thin black bar at the top and disappear within 30 secs or so. Power Saver was just an icon at the top by the battery icon. It looked much nicer. There's also some other minor cosmetic changes.  Other things include I no longer have HTC themes and some other HTC apps.

I have the general idea of how to flash. I just can't seem to find WHAT I need to flash? I've found things like Marshmallow 6 for HTC (pre-rooted). But that's not what I need, is it? I don't need to root to flash according to the above comment.

Hmm, then you probably do need a flash. You don't need root to flash RUUs (factory firmwares), but those you found do need root and/or custom recovery. Whatever it is, I suggest supplementing more details by editing your question - you didn't even tell us your model and system build number (something like x.xx.xxx.x).

Sorry, I'll add more details. I haven't been able to find a RUU with stock marshmallow. I have one for stock Lollipop, though that's not what I need since that's what I already have.

I have found things like stock marshmallow for HTC One M8s and some Galaxy phones. Theres one on the official htc website for marshmallow 6.0 for One M8. Would those work for mine? Would they include Sense 7?

No, don't even think about cross flashing. As of now I haven't found such RUU either... All I could think of is the "hard" way i.e. flashing stock-based images with a custom recovery, but since you specifically stated that's not acceptable, I'm at a dead end too.

How can I stop the Skype notifications from re-enabling?
I have Skype on my Moto G, but I don't use it much. It's primarily for contacting cow-orkers at work. I certainly don't want to get notified every time anyone says one in a group chat while I'm on my day off.
So I switched off the notifications by selecting "block all" in the notification settings for the app. Then I got a notification. So I switched off the notifications again. Then I got a notification. So I switched off the notifications yet again. Then... you get the picture.
How can I keep the notifications from Skype switched off?
Or do I just have to uninstall it?

I don't use Skype to test but this should work  Macrodroid automation app. Trigger: Notification  Received > select Skype and configure or all Action:  clear notifications > clear all. Constraints: Day of week > select your day off. Let me know if it works fine and you want that as a solution to be posted

Skype running in background annoys me so much that I keep it signed OUT when not using.
To turn of notifications of SKype on Android :
Tap the menu icon (three vertical lines), tap Settings > Notifications, then tap Notifications to turn them off.
what you have been doing is , you were telling your android to mute the notifications its better to tell the app itself

That's indeed what I have done in the meantime. I was about to self-answer when I saw yours. Thanks.

Phone sometimes can't detect any WIFI networks
I have a fully rooted Lenovo A328, and at random times, it would just totally not detect wifi. Even if I place the phone right in front of my wifi router, it still doesn't detect it. In the WLAN settings, it gets stuck at the 'Searching for WLAN networks'.
And I also can't seem to turn the WLAN setting off. Heck, the settings would sometimes suddenly freeze also. The only temporary fix I've found for this is restarting the phone, but then, the problem would usually return after a few minutes or so, prompting me to restart it again and again.
Is there a reason for why this is happening? And is there a permanent fix for this?

Trying flashing stock ROM after backing up data.

This is an issue happening because of problem in the wifi module of the ROM you have flashed.
Try to get a fresh ROM and also don't forget to read the bug reports of it.
If you see many download links, download the stable instead of nightly / experimental.
Flash it. Or else, go back to stock ROM

Okay, I'll try that. I'm quite a newbie at this, so it'll take some time.

So, I've been searching around for a custom ROM for my device, and I've come around two particularly good ones: Cyanogen and MIUI. Which one of these is better?

Cyanogen is for you. MIUI is designed by Chinese Manufacturer Mi for their Redmi Phones. We can't predict how your phone react with the MIUI. Go for Cyanogen with your devoce's model number

Your already installed applications will not be affected, instead only the download manager's data will be deleted. By this I mean, all the files, settings or databases ONLY found in the /data/data/com.android.providers.downloads and NOT already installed applications. Also whether you had downloaded them they are placed in Downloads folder of internal sd card or external sd card

I wanted to use Android studio 2.3 and my samsung galaxy note5(android 6.0.1) to run simple default hello world app on my phone, but I got this error message:

All packages are not available for download!  The following packages are not available:
- Package id platforms;android-23

And after closing the message I see this message in a green box in the bottom of the IDE:

Instant Run is disabled: Instant Run requires that the Android SDK for
  the API level of the device you are deploying to is installed. To use
  Instant Run, open SDK Manager and install the missing platform.

Although program works on my phone and it's installed and I can open and see it in my phone but I like to know why I got this error message and how can I fix it?
Thanks a lot!

It simply because you don't have that package installed. Use the SDK manager  to download them. In the SDK Platforms tab, you must also install at least one version of the Android platform. Each version provides several different packages.

Open android studio
Click on Tools > Android > SDK Manager
Go in the SDK Platform tab. To  update an item or install a new one, click the check box so it shows a checkmark.
To update the selected packages, click Apply or OK, then agree to any license agreements.

Check also the compileSDKVersion in the Gradle(app) file and change it accordingly to the platform you'll download

It's installed android 7.1.1 by default and I can not install older one! There is no options!

Android 7.1.1 is android api 25 not 23! You must install android 6.0.1, that's android api 23. Or change compileSDKVersion from 23 to 25 in the Gradle file

I know, but how should I download the old versions?

Ok the problem was internet proxy! solved! thanks

Please give me +1 point!

Recover Nexus 6P that won't boot past Google logo
So I had a random reboot while debugging apps with android studio and after that device doesnt boot past Google logo. Factory reset and cache wipe do not help.
Eventually I found this guide https://drive.google.com/file/d/0Bz6x7k-VkpUJRjl6WjRhVmdXU0E/view. But The problem is that I can't complete step 16 because device is enrolled in Adnroid beta program so there is no public image available that I need (NPG05F). I've found https://developer.android.com/preview/download-712.html but there is no Nexus 6P image listed for some reason. Will it be added soon?
Device OS is 7.1.2 (angler/NPG05F)
So is there anything I can do to get my device back?

Why do you have to follow that guide (taking OTAs versus just flashing a factory image)? Do you have any data to keep?

@AndyYan No, all data can go, it's fine. Problem is that flashing is locked so I can't flash anything except "Apply update from ADB"

To OP: bootloop with locked and non-unlockable bootloader is pretty much dead-end. I've looked around on XDA and it doesn't seem that sideloading a zip could solve it either, but doesn't hurt to try when the NPG05F OTA drops in the future. Shame that N6P doesn't have access to Qualcomm 9008 mode as a last resort as some phones do.

Gray area. Call google and complain about a hardware issue on the power button. It sticks and the phone is constantly boot-looping.  They did have issues with 5x and 6P so if you get someone who knows about those past issues, they may just send you a replacement.  Worth a try...

ROMS for your device and instructions to flash them can be found here: https://developers.google.com/android/images
Hope this helps!

Device is locked, executing "fastboot flashing unlock" returns error. So I think I can only flash NPG05F images

What is the error it returns?

@ejj28 Newer devices require OEM Unlocking to be turned on in the OS before the device can be unlockable by that command in fastboot - I assume OP is bumping into this error. Since the OS is unbootable now you can't just go flip that switch either.

@AndyYan exactly. from all my unlocking attempts/successes on many new devices, recently, you need to boot into OS, make sure play services connects and your phone connects to your cell network before you unlock through terminal.  i root, unlock project fi phones, verizon phones for my job

What I did when my Nexus 6P didn´t boot past Google logo and entered in a loop that never passed that state, was:
First, I entered in the Bootload section pressing at the same time the Power button + the volume-down button.
Then, pressing twice the volumen-down button I chose the Recovery-Mode option. (You confirm it by pressing the Power button)
After that, an Android icon with an exclamation sign logo will appear and below this a statement that says "no commands" or something like that.
Now, to enter the Recovery-Mode you have to press, not at the same time, but first the Power button and without releasing it press the VOLUME-UP button, and a screen with many options will appear.
I selected the "Wipe Data/Factory reset" option and when it finished, I turned the phone off.
Then I turned it on but it kept booting and rebooting never passing the Google logo, so I left it on my desk rebooting and went to my job. When I came back, after a few hours, the phone was perfect and had the screen they have when you for the first time turn it on and says something like "Welcome, choose language".
Summary, reset it to Factory and turn it off. After that turn it on and go for a walk or whatever but leave it rebooting a couple of hours. It worked for me and I hope it can work for other people too.
Greetings!

Does no mention of GPS (on selling site) mean there is no GPS?
I'm looking at the AT&T LG Phoenix 2. It does not mention GPS on either Best Buy nor AT&T, and only mentions a cryptic "GPS Service for location accuracy" on LG's site. (Though phonearena.com does mention GPS.)
Can it be that a phone with a GPS antenna would not be mentioned as having one (why?), or is this a sign that it actually doesn't?

Are there even any phones at all that do not come with GPS? I thought that GPS has pretty much been standard for several years, sort of like how it is nearly impossible to buy a new car without air conditioning.

What is an OS2SD ROM?
I was going to install this CM 12.1 ROM to my phone, but it is listed as OS2SD. What is OS2SD? I could not find anything about it on the internet. Also, the thread says this:

Notes for OS2SD:
  Before you start: I cannot stress enough cwm backups/restoring will not work with this OS2SD release! And data MUST be formated NOT Optional!
  1. You MUST Backup All data or it WILL be lost!
  2. You MUST Format /system, /data, /cache, and /sdcard0 in cwm/twrp.
  At this point you can format sdcard0 as ext4.
  3. Install the new CWM/TWRP the old one will not work from now on!
  If you didnt before now would also be a good time to format the internal storage which in the new recovery is now /data to ext4.
  4. Once formated first flash the OS2SD rom
  5. Then flash GAPPS and/or other packages.
  At this point you can restore data. Note the kernel is special so you cant use older ones so you can only restore things like /data backups and adb/titanium backups.
  6. Then reboot and enjoy the extra space!

Does this mean that my CWM backups won't work? And does OS2SD mean it will format and install to my SD card?
Thanks!

Thanks @DeathMaskSalesman I went ahead and installed the ROM and recovery and it seems that my phone has a partition called sdcard0, which is the user data partition. OS2SD must have been referring to the internal sdcard0 instead of my external SD card (sdcard1), because the OS2SD recovery changed 'sdcard0' to 'data'. I ended up not liking the ROM so switched over to my old recovery and restored a backup. So it seems that OS2SD does in fact install to SD, only on my phone it was the internal SD. Thank you very much for your answer, it helped me a lot!

I'll now post a full fledged answer for you to accept, and for others to improve. Glad it helped.

Judging from the name OS2SD (Operating System TO SD) and from the line that reads OS2SD friendly TWRP recovery, handles partitioning of sd card for OS2SD in this XDA post, it seems that it's a particular flavor of Android that's made to be installed on an appropriately formatted external SD. Aside from that, I was not able to get more info.
Anyone is invited to improve this answer with more info.

Reprogramming Samsung Earbuds' Buttons
I have a pair of Samsung Earbuds which came with my S6 Edge. They have buttons which pause audio and increase or decrease the volume. The buttons only work when it is connected to an android device. Is it possible to reprogram them to move onto the next song or video rather than increase volume? And is this a hardware or software thing?

At least there are several apps to control headset button behavior. Maybe one of them fits yours?

Head set button controller is well spoken of.  Or You can automate also

I don't know if it works with stock rom on Samsung devices, but in CM and LineageOS there's a setting to allow volume keys to switch track by longpressing. Only works when the screen is off, but it works with both wired and bluetooth headsets, as well as with the volume keys on the device.

System language resetting to SIM language after reboot
I recently got a new phone, a Landvo XM100 Plus. It sometimes reboots randomly which doesn't bother me much, but what's annoying is that it keeps setting the system language to German.
I did not have these issues on my old phone (Samsung Galaxy S3), and I don't have the problem when there is no SIM Card inserted. However, I'm using the same SIM that I used in my old phone, so I'm really confused as to what is going on.
I tried googling the issue and I ended up at a few different boards with everyone basically scratching their heads.
Could it be the custom ROM the manufacturer uses? I don't quite want to flash my phone with a different OS right now since I still got a warranty.
Any ideas?

Some phones use the SIM language when the setting  is  set  to  automatic. Try changing the language from automatic to your preferred one.

I can absolutely not find such an option on my phone, I've been through all the points in my settings (even developer options) - though to be fair I don't really know what I'm looking for exactly.  If you mean the "Language and Input" setting, I changed that. Every time. It just resets after reboot.

I was referringto the one in the Language and Input.. So okay, the problem is more complicated than I thought. Only the language settings reset after reboot?

Yup, as far as I can tell anyway. The language is back to german along with the keyboard. The keyboard changes automatically (to QWERTY) when I switch back to english. As I said, this does not occur if no SIM is inserted.  Everything else user-related is saved however, like screen brightness, alarms, volume settings etc. It seems like only the language changes.

I disabled secure start up.
I guess secure start up uses the default keyboard (instead of SwiftKey that I normally uses) and that the language of the default keyboard depends on the sim card.

(Click to enlarge)
I am using a cubot power (cheap Chinese crap) with a Thai and a Danish sim card. Before the fix, the language changed to Danish every time I rebooted

For my device it stopped reverting the language settings after I ticked 'Keypad' in Settings -> Wake-Up Sources, not sure if you have that option depends on android OS version probably.

I have since acquired a new phone (for unrelated reasons) from a different manufacturer. I no longer have this problem. I would like to try and verify your solution but I've had to cut my SIM Card down to fit the new phone, it no longer fits into the old one. If I get around to it, I'll try and see if I can check it a different way.

I just went and got a new sim and it fixed the problem

High "unstability" of phone internal memory
Few days ago a problem appeared. With memory. I have phone with 8 GB internal storage and 64 GB external storage. I keep my photos, songs etc. on external storage of course. Applications are partially on internal and external memory. My phone is Samsung Galaxy Grand Prime powered by Android 4.4.4 (KitKat). It has a root. For a few months, free memory remained at the level of 700-600 MB. Not bad for Android. I know that the level of free memory may vary, but not as much as now. Yesterday the "diagrams of memory" began to jump on the gargantuan value. Only system memory remains the same. Used memory jumps from ~4,50 to almost 4,90 GB. Various files....it's not worth talking. Every second value varies in the range from 43 MB upwards. Several times the pointer took on unrealistic values such as an increase to 700 MB without free memory shrinking, another time memory decided to multiply magically so that the values of all the diagrams exceeded the total memory. Free memory jumped from 625 MB to 140 MB, next returned to ~600 MB and back to ~160 MB. Now it's varying in the range from 160 MB to 150 MB. Can I repair this without hard reset? Maybe it's a kind of memory leak and another bug.
PS. My phone doesn't slow down. And if it's necessary I can do hard reset.

And where is the problem? The flash memory is used by various apps as cache. Hence every action you make in an app may change the free space in the internal or external partition.

The problem is that I doubt that any application can reduce free space from 600 MB to 150 MB.

@BartoszKrólak Well, it has been reported that Google Play Services may take as much as 1GB, even. Still, it's unnatural and illogical for the diagrams to exceed the maximum space available. If you have a custom recovery, make a Nandroid backup, then factory reset and see if the problem sorts itself out.

I have seen greatly inflated file sizes on the thumbnails storage file, which is a sparse file (in other words, it's not literally as large as it says it is--it's more like a reservation of maximum size).  Deleting it always fixed my issues with space, but it gets rebuilt eventually.

MOTO E 1st Gen From Dalvik to ART : com.android.systemui stop and loop
May I first apologize for my english : non-native speaker, some erratic grammar might happen.
Si un francophone passe ici, ce sera bien plus facile pour moi ;)
I'm NOT skilled in android fix, so be patient and please forgive if i ask you more precision to understand what you say !
Some previous questions were on the same problem, but i did not succeed on performing the solution, or [doesn't dare other] for i did not understood it2
I own a Motorola E, 1st Gen, since feb.2015.

Legal warranty void six weeks ago...
No root, no boot, no custom rom.
Kitkat 4.4 (or maybe 4.4.2, can't remember)

In the last weeks, a trouble appeared : i could neither listen or speak to my interlocutor, but by pluging in a wire headset or putting the phone on speaker (the one you shan't but still use while driving). The normal "phone pressed against the ear" did not worked anymore.
The first times, a simple reboot was all it needed to go back to normal.
Since a few days, reboot have no effect.
After an extend search on the internet, i found a solution for the Moto G (2nd gen) that appeared to work perfectly.
Going from Dalvik to ART, which i did friday (march 10th).

1st reboot, upgrading 150 apps
=> Several error messages stated that XXX app has stopped. Then "com.android.systemui" has stop, and i cannot validate the prompt : once I click "OK", it comes back before i could even read the next error message.
I can't do anything with the phone.
==> Reboot by long hold on POWER
2nd reboot, upgrading 39 apps
=> Several messages again, com.android.systemui again
==> Reboot by long hold on POWER
3rd reboot, the same
4th reboot, upgrading 29 apps
5th reboot, the same
6th reboot, the same
7th reboot, upgrading 28 apps.
xxth reboot, the same ...

Today, After a day's rest and no manipulation, count on upgrading application dropped to 27.
By repetivly pressing "ok" and 'report" when avalaible, i somehow managed to get as far as parameters menu.
Can't scoll in the microscopic time given between two prompt.
However,
-> The phone seems to receive calls (it ringed about an hour ago) but not to show the screen (caller ID, accepting the call, etc.)
-> Afterward, the led flashed again.
The android buttons (back, home, active application list) doesn't show up.
And here i'm stuck !
What i tried :

A coffee. Did nothing to the phone, but improved my optimism
Shut it down, let it rest, power it
Fully charge it
Make it reboot by a long hold on power button while it was "upgrading 28 apps".
Pluging it to the computer, to see if it did anything (it didn't)
Making loud assumption on the engineer's mother honour and weight.
Go to recovery mode, and let it boot (if i understand well, it's just a normal boot for long inactivity)
Go to recovery mode, and wipe cache partition
Tried to do this : Moto E is not switching on after changing runtime to ART
=> I made it up to the 5th step ; but 6th don't work "Not recognized as a command or program" I tried the shell on E:\Programmes\AndroidSDK and E:\AndroidSDK\platform-tools. Neither works.

What should i do now ?
Thanks a lot,
Kaldui.

Don't ask why, don't ask me how ... Android automatically reverted to Dalvik.
My best guess is : there is an idiotproof security somewhere that revert automatically after to much fails (at least 20) on booting under the new runtime.
Maybe installing the motorola drivers on my computer before repetivly booting in normal and safe mode while the USB cable was plugged had a positive effect.
Maybe the little bug felt that i painfully resolved to fetch the electronic axe (aka hard reset) and flew away ...
It seems that no data was lost.
It's a true relief !

If you cross this topic, and face the same trouble, well ... it took me five day of patience, two full charge and discharge of battery,
  stubborn booting and prompting closing, ten cache wipe, and utter
  infuriation before everything settled down by itself. Try your luck !

Kaldui.
PS. To the android engineer : i was mistaken, you weren't making overtime to pay the attorney for your divorce, yo mama is a fine women, she ain't this overweight, and her reputation is of a loving, caring and faithful person. I also own you a beer.

Gmail app only partially syncing
I've just bought a Lenovo B phone with Android.
I've added my Gmail account and have enabled the Gmail sync in the phone's settings. It has downloaded all my emails, however it won't properly sync which emails have been read or not.
I read a couple emails on my MacBook using Thunderbird... however on my new phone, the Gmail app says that these emails are unread.
I know it's not a problem with Thunderbird, because I also have a Samsung A3... and my mail on that phone is all up-to-date in terms of what emails are read / unread.
Also the sync settings in my Lenovo say that it has sync'd within the last few minutes (I originally set it up about 30 mins) and this was way after I read those couple emails. So it should have updated them by now.
Does anyone know what might be wrong?
Edit:
I tried sending myself an email using Thunderbird... it showed up on my phone where I then read it. Thunderbird then showed the email as read... however on my device those earlier emails that I read using Thunderbird are still showing as unread... very strange

@beeshyams thanks, I tried clearing the cache but with no luck... how do I reinstall the app as Android wont let me uninstall it? Do I remove / add my Google account again?

Also see this please ,,https://support.google.com/mail/troubleshooter/2650727 - restarting device also helps

Good. You may self answer

Is there a way to post a photo on Facebook on Android without using the Facebook app?
I've removed the Facebook app from my smartphone (Android) because it's a time suck, but I'd still like to be able to post photos of my food (because yes, I am that guy).
There used to be a way to email a photo to secretname@m.facebook.com and have it post, but it appears they've since removed that feature.
iOS can do it because it has Facebook integration built in, but I'm on Android.
I tried the Facebook Moments app, but it doesn't appear to post photos on your timeline.  I looked for other third party apps, but couldn't find anything.
Any other options I have?

Does it work through Facebook's mobile site in your browser? Or is there a specific workflow you're trying to achieve that makes the browser unsuitable?

I'm trying to avoid the mobile website.  I want an app that quickly posts photos to my Facebook timeline and nothing else.

I am also sad they removed the email option.

Yea email would have been perfect for this!  I should write my own email gateway..

You can create an IFTTT account and connect your Facebook account to it (ifttt.com).
Then you install the app from play store (https://play.google.com/store/apps/details?id=com.ifttt.ifttt).
Here's the link to my applet for this same purpose: https://ifttt.com/applets/51211438d-upload-a-photo-from-url-to-user-s-photos
Or, you can create the applet yourself:

go to My Applets -> click on the '+' icon.
for '+this' search for and choose the 'Camera Widget'. In trigger, there is only one, 'any new photo'. Pick that
for '+that' search for and choose 'Facebook'. In 'select action', choose 'Upload a photo from URL'
On the next screen, you can modify how it is posted. Play around a bit with the message until it is to your liking. You can also set an album to store the photos.
Once you're done, tap on the checkmark in the top right corner and click 'Finish'.
you then go back to your home screen and add an IFTTT widget. Once you drop the widget on your home screen, you will be asked to choose the applet. Choose the one you just created.
Now, when you want to take a picture, tap on the new icon. It will open the camera and you can take the picture. It will be directly shared to your Facebook timeline.

Interesting solution!  I'll have to mess around with this a bit later..

How to prevent Chrome from restoring last session?
Whenever I close and reopen Chrome it automatically restores the last session. How do I stop it, so that on reopen it should open homepage instead of last session?
I'm using Android Marshmallow and my Chrome version is the latest one (updated today).

This was possible in earlier versions but from Chrome version 51 onwards, it is not possible as it designed to open in last session instead of home page
I couldn't find any workaround for rooted devices on net
Source

Instead of closing Chrome close all the pages that are open. It looks like a square with a number in it on my phone, next to the address bar, at the top of the screen.

On Chrome close all but one page, set the address as "about:blank" (without the quotes and then form the menu select "Add to home screen". You can then open that with no embarrasment! lol

Nexus 6P accepts touch input, but screen black. How can I pull off a file?
My Nexus 6P is fully working other than that the screen doesn't light up at all. There is one audio file I have to get off it for work. I can unlock it with my pin by estimating where the numbers should be.

Copy web-link with title in Android 7
How do I copy and share a link with title text?
For example, when I 'share' a link from chrome it just sends the URI.
I want to also add the title of the page and then the URI link.

I'm having a hard time trying to understand what you are trying to do,  won't it be easier if you copied separately the link and added the title?

To where you want to share it?

Hi @xavier_fakerat, that will take many extra steps and switching back-and-forth between applications.

Hi @SagarV, I just want to copy to email or chat-app. I remember when I had the HTC, all links I copied had a text title preceding the link. Can something similar be done via a 3rd party app?

The WSJ app I use still has this feature: when I click to "share" an article it will be the text-title, space char, and then the URI.

Paid Messages: Don't ask again
HOW DO I FIX IT? When I was texting my local radio station (which had a less than 7 digit number) my phone said this may add charges to your account  (aka may cost money). And my being quick pressed "never ask me again" then okay but instead I hit declined and it won't let me text any number that has less than 6 numbers and charges me. How do I fix it so I can again?

In Android N;

Android Wear causing battery to quickly drain
I'm currently using a Zenwatch first generation alongside a Samsung Galaxy S6 Edge on Android 6.0.1. Both devices are always fully updated.
The problem is that when my smartphone is connected to the Wear, the battery of the phone drains a lot faster than when it isn't connected. Since my phone is rooted, I'm using the BetterBatteryStats app in order to keep track of my device, and I noticed that when the smartphone is connected to the SmartWatch, the device almost never goes to the DeepSleep state, with the "Awake (Screen Off)" consuming almost all of the device processing time (this doesn't happen when the smartphone is disconnected to the SmartWatch).
My thinking is that the Notification Listener it's keeping the device from going into the DeepSleep mode, so the smartphone can send the received notifications to the SmartWatch. There's something I can do in order to get a better battery life when my device is connected to my SmartWatch?

This sounds like a wakelock issue. Ironically enough I started having the same issue with my Pebble yesterday. Is the phone rooted?

Yes, Ethan. The phone is rooted. Maybe this should be patched on Nougat? Have you tried contacting Google about it?

contacting Google isn't exactly possible. Do you have the "Wakelock Detector Free" app? Install it and add any apps that have more than a half hour holding a lock to the question. Obviously apps such as Spotify hold a lock if you are playing music through them, so those can be ignored.

I'm using it since yesterday. Weirdly, WhatsApp it's on top of all wakelocks (I use that app a lot). There's nothing related to the Watch itself: Bluetooth; Android Wear; Google Play Services; Everything seems normal.

Why can't Android phones record VoIP calls?
I use Republic Wireless so the majority of my voice calls are VoIP.
I use a call recording app to help me recall conversations after the fact. But in order for it to work, I have to turn off wifi and make the call over the cell network.
The recording app made me acknowledge that I understand that no app can record VoIP calls.
Question: why is cell recording allowed, but not VoIP. Is it the OS limitation?  Is it for security? Is it a legal reason?

....why is cell recording allowed,...

AFAIK call recording is not a feature of stock Android, though certain OEMs and custom ROMs enable it or can be done using apps. I guess legal restrictions is the reason for not enabling  this feature, as call recording laws widely vary
VOIP recording is quite different from voice recording
Firstly, it is possible:

App recording VOIP calls  is possible, see Call Recorder - IntCall for instance. There may be others too
Non app based services that record VOIP calls seem to be more - Dingtone, for example

What is common for VOIP recording and different from voice recording is that VOIP recording is done when it is routed through the servers provided by the app (see description in both links above). Ordinary voice recording is not bound by such limitations and can be natively record if enabled on device
Call Recording Software Wiki

VoIP Recording
  is usually restricted to streaming media recorders or software developed by the softphone or IP PBX creator. There are also solutions which use packet capture technology to passively record VoIP phone calls on the LAN.

Since VOIP is using data packets to transmit voice, these packets need to be actively or passively sniffed ( see wiki above for details) and this requires dedicated setup unlike voice recording ( which can be done natively on phone (if enabled) or using apps ). Hence, VOIP recording is not simple to implement on device like voice recording-  a technology constraint

You answer sort of makes sense to me. But what doesn't make sense to me is, why can't any audio going out your phone's speaker just be recorded once it's been decoded ? On my PC, I can just tell my sound card to record audio from any number of inputs via a software mixer. Is there some sort of hardware limitation where the mixing circuits just don't exist in mobile phone architecture (perhaps as a power saving decision) ? I suppose it's equally possible that the software mixer doesn't exist on the phone OS for the same power saving reason.

That wikipedia article is a bit lacking in actual verifiable content. It says Hardware is required to make the voice signal available to the computer equipment., but doesn't cite any actual reference material.

Thanks for accepting - I am not really sure what the limitation is , and  I would go with hardware given your PC example. If I come across specifics, will update

Please don't misguide. VOIP recording isn't possible due to sound Input device restriction. If a VOIP is working it occupies the "sound input device", as a result recorders will fail to record. It is simple as that. No other guesses.

Please don't misguide? I guess the one misguiding is you. If you call through  the sip protocol,  then you can use CSipSimple. In call options,  you can activate the call recording feature. It works just fine.

VoIP calls cannot be recorded as of now in Android.
Normal Calls dont use microphone so another app can acquire microphone and record the conversation.
But in VoIP calls, the app would be using the microphone so another app cannot acquire, if it tries it fails with an error. If the recorder app tries to acquire microphone before the VoIP call then during the call the other side will not be able to hear anything.
So bottom line is, there is no such app as of now to record VoIP calls in Android.

How can I make Android M stay connected to a weak wireless network?
I recently switched from an older device running CyanogenMod 11 (Android 4.4 / Kitkat) to a newer device running CyanogenMod 13.1 (Android 6.0 / Marshmallow).
Both with this device and with others, I've found that the newer versions of Android are much less willing to connect, or to stay connected, to WiFi networks with a weak signal strength.
I assume that this is due to Android 6.0's renewed focus on reducing power consumption… but it is a problem for me because my device often has a weak WiFi in many parts of my workplace. This was not much of a problem under Android 4.4, but causes me to lose my connection frequently under Android 6.
I remember that stock Android 4.4 had an option to "Avoid wireless connections with poor signal strength" or something to that effect, but there seems to be no such option in Android 6.0.
Any good way to convince newer versions of Android to connect to weak WiFi signals?
UPDATE: Seemingly-related bug report, wherein many other people complain about the removal of the "Avoid poor connections" option. https://code.google.com/p/android/issues/detail?id=81843

I don't think losing connection have something to do with lowered power consumption, It may be releated to wlan chip so it have less streinght than others. Also I noted that on custom roms range is lower than on stock firmware specially on devices that doesn't officially support x version of android and you have custom rom of that version.

Why would custom ROMs have a reduced WiFi range as a general matter? This device was officially released with Android 6.0 and I see no reason to think the custom Android 6.0 ROM should be any worse in terms of WiFi support.

Because I have expirenced it. I had a phone which when on stock rom could stay connected to particaular network but when I flashed custom rom (6.x) phone couldn't even reach that network, while I was on 4.4.4 custom rom I had a wider range than on stock (4.1.1) and better stability. So it releated to hardware possibilities and than it can be tweaked a little on different versions of software. You can't give to hardware more/less power than normal otherwise you would damge it. What can be releated to battery consumption is if your wifi is turning off when locked.

If your wifi is losing when you use the phone it's due to hardware (80%) of phone or router whatever you like to say.

I already have set "Keep Wi-Fi on during sleep = Always". I'm not particularly convinced that custom ROMs in general should be any worse for hardware stability. For the most part their kernels and drivers are built from the AOSP kernel sources, in the same way as official vendor builds are. (I do have a decent amount of experience debugging and building wlan drivers for the mainline Linux kernel.)

It switches to mobile data or other WiFi channels withing range it just switches of WiFi. ??

@user145490, it simply switches to mobile data instead of WiFi.

Music players don't see my music
I loaded a bunch of music onto my Samsung Galaxy 6.  The songs are there because I can find them using MyFiles and can click on them to play them individuals.  However, every music player app I have tried does not see these files so I have no control over them to do things like create playlists.  In the MyFiles app they are in a folder called Audio and all mixed together.  DeviceStorage/Music contains the actual CD names but when those folders are opened in music apps, it says no files. I can actually play them from the Samsung MUSIC app but bizarrely this is accomplished by selecting "Verizon Cloud" from the menu and it is always going on about "waiting for backup".  I have tried 4 different music apps and none of them seem to be able to locate my Audio folder which I see in MyFiles.

What about google play music

Note to future readers: Depending on how the songs were copied, the media scanner might not yet have cataloged them – so music players relying on its catalog won't see them. Easiest way to fix that is rebooting your device, as at boot is one of the times where it definitely runs the scan. Factory reset should not be needed; it would also delete all contents and thus not be really helpful ;)

What App is this?
From times in times, when I unlock my screen comes up an automatic installation attempt, blocked by my settings (block from unknown sources). I would like to know if this app, called Calculator Exchange is a safe one to install.
KitKat 4.4.2
Z4
Thanks a lot in advance.
Sandro Vieira

If an app prompts always, it is not safe to install.
It is an ad by any of the app in your phone and it may or may not be a malicious app.
If that app is from playstore, it is less vulnerable but it is directly from an apk. So it is highly vulnerable.
Go to filemanager, search by possible keywords, find and delete the apk file.

Your device might be infected with virus that is actually trying to install the app Calculator Exchange. So I strongly recommend you to take backup of you data such as contacts,photos,videos,etc., and Reset your device to Factory settings

Android doesn't have virus, but malware. If the malware resides in the /system partition, a factory reset won't help.

For that we need to hard reset the device.

Incorrect. To remove a malware located in /system, you need to reflash the firmware.

LG Watch Style USB Debugging - computer not recognizing presence of watch
I am trying to develop for my LG Watch Style and I am having trouble getting my computer to recognize its plugged in. I've tried reinstalling the Google USB drivers and resetting the watch.
It's almost like the charger that came with the watch is not capable of sending data.
Does anybody know any debugging secrets?

Looks like the LG Watch Style's charger has NO DATA PIN.
The workaround for me was to use Bluetooth debugging, you will need an Android phone with a USB cable and a computer running the ADB server. Wifi debugging is also an option but that requires a USB connection initially (maybe it can be bootstrapped through bluetooth?)

Can't believe LG actually did that...

Google Play Services: Wrong Architecture. Can't change
So I've got a problem with Google Play services where it's stuck in an arm64-v8a architecture while my phone's is armeabi-v7a. It happened when I tried installing a beta version of Google Play Services 10.5.35 for arm/arm64 (XYZ=448). I quickly received the error about an incorrect architecture for my phone (Alcatel Pixi 4, android 6.0. I have a 16GB SD card formatted as internal storage. Google Play Services is built into the phone).
I've tried installing other apks which should work (438/430, beta and non-beta) but they simply gave the error "App not installed" when I did.
I've tried uninstalling Google Play Services' updates but couldn't find the option to do so (or at least, it's not where it should be according to some websites).
I've performed a factory reset (without restoring a backup).
I've tried using Apk Installer.
Still, nothing has worked and the error remains. I need some way to get Google Play Services to the latest version, preferably beta. Also, I'd really like to avoid rooting my phone. I'd be so grateful for any help!

Amazing! The whole thing just fixed itself after an update via the Play Store! I'm so glad it actually got fixed! I guess to anyone with a similar issue, this should be good to know. Altough it's a shame I could only wait for this to happen, maybe there's some way to speed up this process.

Deleted Google Play app by accident
My friend accidentally deleted his Google Play Store app. It is a Samsung phone. I don't know much about android because I use apple.
I clicked on settings --> app manager. It shows that Google Play Services is still running.

Does this mean the phone is jailbroken? How can someone delete a system app?
How can I get this app back?

please explain, how play store deleted? maybe he just removed app icon from home screen.

He doesn't speak English very well, but he says that he just deleted it. Assuming that he just removed the app icon, how can I get it back?

it will be there inside apps(app launcher), press on playstore and drag it to home screen.

The app is not there

You can download playstore apk from any below answers, and install it, that will solve this issue.

As Playstore is a system app, he cannot simply "have it deleted". Most likely, he just disabled it. Please check in Settings › Apps (or "App Manager", "Manage Apps", or whatever Samsung has named it) for Disabled apps. I bet Playstore is amongst those. Tap its entry, hit the "Enable" button, and it should be back. Please confirm.

The google play services are listed there but it only gives the option of disabling it.

first of all not jailbroken the word is used for Apple. for android, we use Root
The device is rooted I think. Otherwise, the system app cannot be deleted.
This google search will give you a lot of result. Download and install a playstore from it.
google play store apk download

Agreed on "The device is rooted I think. Otherwise, the system app cannot be deleted." As OP would know if he rooted the device, I rather assume it's not rooted, and the app was simply disabled accidentally.

The other day I did a hard reset on a htc that I didn't know was rooted I found out it most defiantly rooted when it booted up and it didn't have google play services no App Store. I basically did the same thing they are suggesting  for you to do  it works fine. I used a site called APKbucket I thought it was a little sketchy at first but it been safe so far and I've downloaded some pretty kickass apps. Good luck

Download Mode. What does this mean?
RP SWREV B:3 K:0 S1
Searching online, I haven't found any clear information.

Is your phone bricked? Doea it not pass the logo screen?

What is the actual problem? Are you just curious about what download mode is for? Did you get into download mode by accident? Does your phone boot in download mode every time you turn it on?

download mode is related to recovery where your device is ready to accept a new system image from the computer.
It is used to flash a new OS to the device.
In download mode, you can inject and install the OS (flashing).
but be careful while using this

I meant what does this line in download mode means RP SWREV B:3 K:0 S1

@Kenny it apparantly is the software revision installed on your device.

Change existing email account server
I am running Galaxy J5 with Android 6 and I need to change server settings for existing email account.
Way used before
From the Email app, press the menu key, then choose Settings. Pick Account settings, then click the account you want to change on the next screen.
After that, you have to scroll to the bottom to get More settings, and to the bottom again to change the Incoming settings and Outgoing settings.
Does not work because there is no More settings or settings at all.
Also settings-accounts-email there are no settings.
Where is this setting hidden please?
Thanks

If you want to change your connection from IMAP to POP3, you must delete the email account and recreate it as a POP3 account.

That is something I would like to avoid. Anyway if I need to change something like signature or sync frequency, where is it?

Gmail > settings >choose account > change sync frequency,signature and other settings

Unfortunately this works only for gmail account. I have some others + one exhange which are not available at gmail app

Settings > account> you can see other accounts like Yahoo, Dropbox etc. You should find your exchange app there. Either you should be able to change from there or from within the app. I don't use exchange. In any case, please edit your question to make it specific with examples so that others can pitch in
