Android: something is using up all my wifi
This is the problem I have, and it just started today. When I start my wifi, everything seems alright. I can use the internet. Then, something kicks off that uses up all the wifi, and at that point, nothing works.
Based on what's happening in the apps, it looks like all of their requests are timing out. The icon shows that I'm constantly uploading/downloading, despite their being no apps on.
I've turned it on and off multiple times to no avail.
What could be doing this? How can I track it down?
Thanks!

Does it happen in Safe Mode?  If not then you have an application, that is configured in your normal boot configuration, using all your resources.  You can use something like AutoRuns to determine which application it is.

Does the issue persist if you set the wifi on the device to "off" then "on" again? Is there a "login" page when connecting to that wifi? (Like what you would see at a hotel or airport?) - Finally, is there issues with any other devices?

@NBN-Alex this is not a hotel or airport wifi. There's no login. It's my work wifi. Nothing has changed there. No issues on any other devices.

@Ramhound I rebooted in safemode, and it looks like my wifi is still being used non-stop. Now, it's showing the synching icon as well.

@Summitch do you have access to your router's login page? If so you can login to the portal and look at connected devices on your wifi tab and it should show you signal %.

@Mr.Hargrove no, I don't currently have access to my router. I'm at work.

@Summitch So this is not your wifi network? If so many devices could be using the wifi for a multitude of different things, many of which can slow the wifi network down.

@Mr.Hargrove This is a business wifi. It's most certainly not the issue. What I'm pointing out is that it's not just my Wifi is slow on my device. It's that my device shows the Wifi in constant use. It's also heating up. It's like it's working really, really hard on something that's using the network, but nothing should be on.

Would you be able to post a screenshot of the data usage screen and the Running Processes tab?  There's so many possible answers but I'm thinking it's possible there's a sync of something in progress

@Summitch download a network analyzer like this: http://www.techet.net/netanalyzer/ and it should possibly show what's using the wifi.

Backup an LG watch urbane
I'm now trying to backup my Android wear. I got the drivers from the official LG website, but nothing appears when I plug it in. Driver manager reports no errors, so i guess it didnt detect the watch. Usb 2.0. Can someone help me on what to do? Thanks.
Technical setup: Usb 2.0 (my connection) Windows 10, using charging dock.

Please add more details about the exact behavior you're seeing and what you are doing.  I assume you're on Windows -- what version?  How are you connecting the device (USB2 / USB3)?  Was the device detected (& drivers installed) the first time you plugged it in?  What does the Device Manager show as the entry for this device -- is there an error?

@MatthewRead just edited-reopen my question.

Edity, try using the LG BRIDGE. Here ya go: http://www.lg.com/us/support/product-help/CT10000026-1438110404543-preinstall-apps

I did use the LG BRIDGE

Share WIFI from PC over USB
All the questions with similar titles are the inverse of what I want. I would like to connect my tablet (that is "blocked" on the Wifi) to my Windows 10 computer over a USB cable and have the computer "share" the Wifi. Is this possible?
EX: My tablet is blocked from the internet (home policy) but you can get Wifi by asking and staying in the main rooms, I want to have my tablet access the internet by having the computer "share" the internet with the tablet. I don't know if this is possible and if it is would like to know how.
I have a Nexus 7 2013 32GB Wifi on 6.0

I am trying to understand this: Your tablet doesn't have wifi you want to connect it to your computer via USB cable? Yes this is possible- normally when you attach your android device to PC it automatically installs MTP driver to enable you to browse the device folders. Secondly what programs which require admin rights are you trying to run ( I assume on your PC?) Do you wish to do file transfers of some sort between the 2 devices?

I thought I could comment on this before writing an answer to get clarity. You wish to share the internet from your computer over wifi because your tablet is blocked to access that particular wifi? . Short answer yes it is possible to share your wifi to give your tablet internet access, in this case there is no need for usb  **unless your pc doesn't have a wireless card in which case you need to perform what is called reverse tethering

@xavier_fakerat yes pretty much, I think you understand, the nexus is blocked on the wifi (it can connect but the router will not let it access the internet)

Different ways of sharing interet connection from Windows to other devices
Nowadays there is a lot of ways to share internet connection to other devices and each method has its pros and cons.
Here is a breakdown of methods:

Using Windows 10 Mobile Hotspot Feature:

Newer editions of windows 10 (after 1607 anniversary update) have a built in mobile hotspot feature which allows internet sharing to other devices
pros

easy to use as its built-in
no extra tools needed
internet is shared over Wi-Fi (no need for cables)

cons

some network types are not recognised e.g 3g dongles.

Using 3rd party tools
Nifty tools such as mhotspot,  or Connectify provide the ability to share internet to other devices by making use of Microsoft Virtual Wi-Fi Adapters

pros

provide many additional tools to monitor and customising  created networks
improved encryption
internet shared over Wi-Fi

cons

some of these are commercial softwares and  are relatively expensive

3a. USB Reverse tethering
Reverse tetherng is a relatively newer method of sharing internet especially from devices that do not have a wireless adapter.
 It uses the USB cable to share internet from the computer to the target device and oftern requires 3rd party tools and drivers as well as system modification of target devices.

Reverse Tethering (root)
Requires the target devices to be rooted prior to connection and a USB server application or server to be installed on android. For better coverage this method often requires another Xposed module Hack connectivity service to increase internet coverage to most apps if not all.

Reverse tethering (no root)
Similar to root based method but requires extra programs to be installed on windows

Specific requirements of reverse tethering no root:

Java runtime environment (JRE)
PC server application
Android server application

pros
 - can provide faster connections usually with low latency
 - reverse tethering (no root) works on windows, linux and mac
cons

requires usb cable
installs additional apps on PC and phone
connections can be difficult to establish
some of these workarounds only work for some apps and not every app is guaranteed to have internet access, but from my experience browser, Gmail, google play were working just fine

Update
3b. Using  adb to reverse tether
Using bash script
alias t='r && sz $tether && r && sz $n'
tether='am start -n com.android.settings/com.android.settings.TetherSettings && input keyevent 66 && input keyevent 66'
n='netcfg rndis0 dhcp'
alias sz='ad shell'
alias de='ad devices -l'
alias r='ad kill-server && ad start-server'
alias ad='adb'
alias pu='adb push'

Special thanks to user42276 for this script
Pros

One good thing about scripting is that it eliminates the need for third party apps which may bloat the device/PC

Cons

Pretty much similar to method 3a above

Using Windows ICS

Another way is to just use ICS in Windows with no third party software involved:
Requirements:

Terminal Emulator on your Android
Alternatively using adb shell commands (to use adb, you need to enable "USB debugging" on your Android).
Optional, BusyBox on your Android.

Instructions

Connect your Android to PC by USB cable and enable "USB tethering". You are still allowed to enable this option even when your 3g/wifi on your Android is off.
Windows will automatically search Windows Update and install driver for you.
Open "Network Connections" in Control Panel. Right click on an Internet connection that you have i.e WiFi connection (other connections like LAN also work), so right click on WLAN connection with Internet, and select "Properties".

In tab "Sharing" click "Allow other network users to connect through...", then select the USB connection in dropdown list below.

Click OK. Windows will automatically setup your USB network connection and assign to it an IP address (usually 192.168.xxx.xxx or similar; for Win 7 and later its 192.168.137.1)
Your Internet connection is now "Shared" and your USB connection is now "Unidentified network".

Type the following command in Terminal Emulator:
netcfg rndis0 dhcp
The name for usb interface inside Android may vary. It is usually rndis0 or usb0. Type busybox ifconfig to identify the name.
It can happen that automatic dhcp method does not work. In this case we have to do it manually:
Type these following commands in Terminal Emulator:
ifconfig rndis0 192.168.137.2 netmask 255.255.2 route add default gw 192.168.137.1 dev rndis0

If route fails, try:
busybox route add default gw 192.168.137.1 dev
Some applications (download in Google Play, Gmail, Facebook...) don't recognize the internet connection. You can try this way:

Enable temporarily 3G connection on your Android
Type: ifconfig rmnet0 0.0.0.0
The name for 3G interface inside Android may vary: ppp0, rmnet0... (Type busybox ifconfig to identify the name).

This will make applications see your Internet connection via USB as 3G/4G
Well its up to user to know which method suites them best. Hope it helps

Will possibly accept and give bounty once i try one and it works

Thank you please let me know if the method you chose works, I will be glad to assist further

@xaiver_fakerat yeah i chose the first one and it worked. I will give the bounty tomorrow (I can't award it for another 20 hours)

No problem  @Down Christopher, I  am glad I was able to assist you that's what matters to me

sending AT command with NCK code unlock sim?
I need information. How can I send the NCK unlock code network using AT commands? Or is there any other ways?

Depends on the who made the phone and the AT command set they support. I did this recently on a ZTE Modem using AT+ZNCK I believe, but that command isn't a standard one across all manufacturers! Trying to do it again on an LG, no good luck so far.

look. on any phone has an interface for inputting code NCK. this is a normal apk. I decompiled it and looked at the code for my Micromax Q415, there was PhoneFactory.getDefaultPhone (). getIccCard (). supplyDepersonalization (). This method nck code sent to the modem. but I could not find how he does it. I can either call this method and learn how it works and do the same. I'm right?

Look like AT+CLCK is the closest thing to a standard way across manufacturers. But again, the actual name of the lock varies by manufacturer. I'm trying to unlock a JAVA-based feature phone, can't use API.

What is he doing  supplyDepersonalization, if AT+CLCK absend ? I can't find. How to find out?

Google Sync - Accidentally synced work contacts
Recently bought a new Android phone after switching from iOS. Moved my iCloud contacts into Google contacts and then added my personal and work Google account to my Android phone.
My Android phone is now showing 1000's of contacts because my work contacts have synced by mistake (only need the personal contacts on my phone). So I've disabled sync from my work account but all the contacts are still on my phone?
How do I 'reset' my phones contacts (and other sync info such as Calendars) so that it only shows and syncs with my personal google account?

I don't believe you can do this from your phone, but you can actually restore your phone's contacts to a specific day/time. Here's how you do it in Google Contacts Preview:

Reset app preferences
Clear data/cache and uninstalled updates
Remove google accounts
And even Factory Reset.

But its still not working.

if you have a custom recovery installed you could try flashing a Gapps zip

Or simply flash your phone with a stock firmware. You may have been hit by malwares

Cannot hear my notification sound on my Samsung Galaxy On5?
Okay, so I got my new phone (A Samsung Galaxy On5) about 2 months ago, and just recently, the notification sound stopped working. I checked to make sure that it wasn't on silent or vibrate, and it's not. The sound is on, and ringtone is on too, but ringtone is the call sound. Instead of emitting a sound for my notification, it just vibrates. I've tried powering it down and back on again, but nothing seems to work. Help?

WiFi doesn't work when SuperSU 2.72 binaries are installed on Android 7
Since a few days I have Cyanogenmod 14 for my Samsung SM-G900f. I want to use some apps by Chainfire but they all require his su binaries so I tried to install it via the SuperSU app, which always fails, and via TWRP, which then worked.
After flashing it I noticed that I when I turn on WiFi that it just scans but nothing appears; even the already saved networks won't show up. I also tried connecting via WPS pin and WPS push, but it just gives me an error message.
Does somebody have any idea what the cause might be?

Try the latest SuperSu Beta: http://forum.xda-developers.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133

It didn't work. Same results.

Better you uninstall SuperSu app and binaries and use CM's Default Root Access (from Developer Settings) till the issue is fixed..

On 30 Nov, 2016, Chainfire Releases SuperSU v2.78 SR5, Fixing Some Nougat Bugs

Today, he has released yet another update to SuperSU, and this one focuses on some Nougat related bugs again. In a Google+ post, Chainfire tells us that some scripts and services weren’t able to be executed thanks to some modifications SuperSU makes to SELinux and the stricter service execution rules in Nougat. This didn’t happen on all firmwares, but this did lead to Wi-Fi, cellular, and other modem-related features not working on some of them (like the Samsung Nougat beta and CyanogenMod 14.1).

How can I remove a System App from my rooted phone?
I have rooted my device, and removed several System apps successfully, including this one. However, I then accidentally restored this particular app and now I seem to be stuck with it.
I've also tried deleting it's file through a few File Management apps, but to no avail.
The problem is, I think, that when it was restored, it was restored as a System App for the root, rather than as the regular system app that could be removed, that it was originally. If this is the case, is it worth trying to unroot my phone?
This app that I'm trying to remove is YouTube, by the way.
Any ideas?

Likely it's because the application your trying to remove is refusing to let it's services die gracefully. The trick I use involves ROM Toolbox and works for most applications including the last time I had to uninstall YouTube. I'm using the paid version so some features described my not be available in the free version.
If using ROM Toolbox, then click the applications manager within it and select Freeze before selecting uninstall and the application will be forced to quit and not able to start again. However, do be sure to make a full backup of your whole phone either though custom recovery or ADB because if you freeze some applications (other than YouTube) it'll cause your phone to barf or bootloop until restored.
Additionally some applications will still have some hooks still running after uninstall so reboot to have that flushed from memory.
Lastly don't go using this freeze ray trick on system applications because that'll often cause bootlooping and other issues. If you do freeze system applications and the device still operates then don't uninstall the frozen system app because this can also cause bootlooping when system integrated apps try to access the uninstalled app.
Apps I know cause issues (some more than others) when frozen are; stock messaging, play store & service, phone application (even on tablets), clock and system; don't ever freeze the system or UI app unless you like restoring from backup.

Have you tried rebooting the device? Also you can try removing the app with Purify if you rooted your device with KingRoot

Tried both, but no go, unfortunately.  I originally used the Titanium app to back it up, and then uninstall it. I restored it using that backup.

and Titanium cant uninstall it?

That´s what´s so strange - I had no problem uninstalling it before, but after restoring it, I can´t seem to uninstall it again with Titanium, or any other such app.

Is there a Youtube apk in your data/app folder? if yes try deleting it

More like /system/app, but yes you should be able to manually remove the APK.

@Matthew Read, ShulkerHD, I've tried that too, with read/write access.

Try using the bloatware removal function hidden somewhere in the settings or so. It might solve the problem.
EDIT: Titanium Backup -> Main menu -> Preferences -> Bloatware Melter

Would you be more specific on the the detail you wish to give as a solution? If the funtion is hidden "somewhere" then how can the asker find it? Be sure of what you saying else its better off as a comment or at least spam.

I've never heard of any built-in "bloatware removal function", hidden or not. So I'd very much appreciate some details on where exactly to find and how to use it. Especially if it's hidden, your post crucially needs to be updated with those details to make the post an "useful answer" – as otherwise we beard can't reach that honey ;) Thanks in advance!

Each phone is different. On one phone a certain "bloatware" can easily be removed. On another it will cause a bootloop. A good starting point is to google "remove bloatware " and you should get some lists of apps which people have "safely" removed. Can never be sure about those lists though, so make sure to have Complete Backup, so you can always go back to previous state and continue experimenting.

there is an app called System app remover(ROOT) on the play  store , which enables you to remove any system app. also it gives you backup to restore it anytime. don't forget to restart android after uninstalling app since , it requires restart to take effects. i am providing you the link:
https://play.google.com/store/apps/details?id=com.jumobile.manager.systemapp&hl=en

I'm fairly sure there are no apps out there that can give an option to restore any System app. This is because removing some system apps make it impossible to return to the OS again or run the app. So the only option is to use Recovery. So make sure to do complete backup from your custom recovery (TWRP etc) before you remove/disable any system app.

Apps not updating
No matter what I do, my apps due for update are going on downloading. The Notification bar shows paused. I have factory reset my play store, it worked the last time, but not now.

So this may be a silly response, but have you tried turning off and back on your phone? It usually kicks things like that into shape, in addition you could try turning on and off airplane mode.

Things that could cause this:

Time/date not correct on your phone
You have changed the password of the email address associated with your Play Store
You are out of space on your phone
Your Google Apps framework needs to be updated

How to reboot an Acer B3-A20 into safe mode?
When holding down the Power off button on the screen, nothing happens till I let go, and then the system just powers off.

This guide is not exactly for your model, but it will probably work on your model, too:

Turn on safe mode

Turn device off.
Press power button.
When the "Acer" logo is displayed, release the power button.
Immediately after releasing the power buton, hold the volume down button.
Keep holding down the volume down button until the phone finishes rebooting.
Release the volume down button when you see Safe Mode appear in the lower left corner of the screen.

Deleting log files on galaxy tab s 10.5 sm-t800
I have a rooted samsung galaxy tab s 10.5 running android 5.0.2
I am having a lot of storage problems and deleting apps doesnt work, the storage just gradually decreases.
I read somewhere that the log files are supposed to be in /data/log but there is nothing there, i am using es file explorer with the function root explorer on. i have already checked if my device is rooted correctly but there is nothing wrong with it. Also using other file explorers doesnt work.
Where could my log files be? (Or other deletable files that use a lot of space)

Welcome to Android Enthusiasts! You could check our insufficient-memory tag-wiki for hints :) Besides: most of the logs (at least the system's) are not files, but rather a ring-buffer in memory (oder entries get flushed out when the buffer is full), see our logging tag-wiki for details.

Please see this new article 2017/02/10 10 most useless apps and games for Android. Most prominent, but specifically named in the list: ES File Explorer (along with quote-Booster apps, Anti-Virus apps, and Task Killers-unquote)

If the file explorer cannot find it,  I suggest connecting it to your computer.  If you cannot find the log files there,
 Take note of folder sizes.  Check back every few days and see which folder has grown in size.
This may lead you to whatever is taking up space.
Hope this helps!

Asus zenfone 2 laser factory reset bypass owner's mail authentication
I'm using Asus Zenfone 2 laser Android device. When I bought the device one of my office colleague did the set up for me. Yesterday I did factory reset. After reset I tried to access my mobile. It asked me to use Owner's Google account which I used before in that device for sync. I do not have that mail id nor do I have that person's contact.
I have the bill for the phone. Is there anything I can do to bypass this authentication?

That's called "factory reset protection" or, in short, FRP. I've never dealt with it personally, but others have: Please see our factory-reset tag-wiki (yes, our tags have wikis :) and follow up to Bypass “Verify your (Google) account” after resetting plus other helpful posts.

In superuser app what does force user do and what are there meanings
I'm using a Samsung Galaxy tab Pro 10.1
I have rooted my device and I have general knowledge  but I am not an expert on tablet settings and controls so I would like to ask the following question's.
In the Superuser Pro App, what is "Force user" and the following actions mean.-  :  Nobody, Net_BT, Net_Raw, Net_BT_Admin, Inet, Root, Radio, cache, shell, Media, Install, ADB, Compass, Graphics, Camera, Mount.
What are they used for, or does it depend on what app the superuser is granting access to? Some of the abbreviations I know, like Install means Install an app, or Camera means use camera, but the rest I don't know there meaning and what they do,or when they should be enabled in " Force User "
Could anyone please explain what the meanings are and when you should use these actions in "Force user"?

Net_BT, Inet and so forth, are special users called AIDs (Android IDs). Those users are each in charge of a particular component of your device. The Force user option, when coupled with one of the abovementioned AIDs, lets an app act as one of those, granting it full power over the AID's specific domain.
If you think about the AIDs as kings, and root as a god, then there's usually no need to impersonate one of the AIDs, for root has power above each of their domains.

Can rooting remove all malware, viruses and backdoors?
I ask this question because I read somewhere that there was a Chinese smartphone with in-built malware which could not removed even by rooting.
(I searched the article everywhere but couldn't find it. So, no source. Sorry!)
Is there a possibility that any kind of malware or virus, that could harm your device and/or your privacy, will remain even after rooting your device?
EDIT: By rooting, I actually meant rooting and then flashing a custom ROM, i.e, reinstall android. Sorry for the confusion.
Can malware and viruses persist after this?

Probably my question is related: http://android.stackexchange.com/questions/164880/how-do-i-fix-malware-installed-automatically-in-the-system-directory

Maybe this is the news article you're talking about: Chinese-authored spyware found on more than 700 million Android phones

Even after installing custom ROMs some area on the internal storage is left unchanged and if the malware resides in that area of the internal storage it won't be deleted even after you flash a new ROM but it is a very rare case when a malware goes so deep into the system.
If you want another example for this then try to install a boot logo (i know it isn't a malware) but even after you flash 100s of ROMs it will never change the boot logo of your device and this proves that some code remains unchanged even after flashing new ROMs

What area that are both unchanged between flashes and stores executable stuff could affect userspace? Boot logo is a bad example as it strictly accepts files of very specific format. /data and /system are wiped when installing a ROM. /tmp and many are only generated on each boot.

Is there a way to clean everything?

What are bootkits? Obad? Oldboot?
https://www.bleepingcomputer.com/forums/t/601716/recurring-malware-immediately-after-factory-reset/?p=3905554
Can bootkits persist even after reinstallation of OS?
Are these what you were talking about?

Rooting allows you to modify the system and access all app data. It does not change anything regarding already installed installed malware or virus.
If you have rooted the device using an exploit the installed malware may also use this exploit to get root access.
Conclusion: If your device is infected delete it and reinstall an untainted system/image. However advanced malware may even survive a installation of a new ROM potentially in partitions that are not erased or in flash roms of embedded chips.
Therefore the only 100% secure way to get rid of malware is to physically shred your device. No device - no malware.

What I actually meant to say was: rooting followed by flashing. Sorry! Can this ensure that all malware, viruses and backdoors are removed?

What are bootkits? Obad? Oldboot?
https://www.bleepingcomputer.com/forums/t/601716/recurring-malware-immediately-after-factory-reset/?p=3905554
Can bootkits persist even after reinstallation of OS?

Rooting doesn't have anything to do with removing malware. Rooting is process when you get a superuser on your phone so you have full control over device (like accessing all files and folders etc.) What you can do is to remove system apps. And those chinese phones had malware probably on kernel level or built in into system, not as application.

How do I remove malware at the kernel level or built-in into a system? Will reinstallation suffice?

@Stack-Boi You can remove it with flashing custom rom in which malware is removed.

Can all malware be removed by flashing custom ROM? This was the question I originally intended to ask.

What are bootkits? Obad? Oldboot?

@Stack-Boi Maybe, maybe not you'll know when you try it's not exact science

Xperia Z3 bootloop after TWRP
Xperia Z3 D6633
I followed the very many tutorials (pick any on google) saying to flash (in fastboot) the file bootZ3monxtest01.img
fastboot flash boot bootZ3monxtest01.img

Now I have a bootloop around the sony logo.
No system, only recovery (TWRP) available
I can also reflash the whole system through Sony's Flashtool, but it kills the point, as a custom working recovery is required for later rooting
Obs. 1:
Needless to say that the "usual" is to flash recovery onto recovery partition. I tried that. Nothing happened
Obs. 2:
KingRoot rooting method worked, but I fail miserably to replace it by SuperSU
Obs. 3:
It's my third attempt
:(

The Flashtool also provides a rooting option, you can give a try. Just connect the phone with ADB and hit the padlock icon.

Yes, yes ! That's an important detail that I forgot to mention on the main post: tried this built in tool both in flash mode and fastboot. Both returned an error that unfortunately I cannot remember. Can't remember either why I didn't try to research about that error... Could've resolved the issue much earlier...

I found another method (buried lightyears deep on the net):
http://squidstech.com/2016/11/27/root-z3-23-5-a-1-291-d6603-d6633-d6653/
It flashes the recovery via ADB
(requires a prior kernel change, though, that can be restored after)

Always show next Calendar appointment on lock-screen
One feature I dreadfully miss from Windows Phone was that my next calendar event was always displayed on my lockscreen:

I now use the Outlook application on Android to manage my daily life. Is there a way to enable a similar feature on Android?

Afraid not without root. That feature was available until someone decided to ban it with the release of Android 5 (Lollipop).

I missed this one badly.

This is a far cry from what Windows Phone OS offers out-of-the box, but of everything I tried recently, the least worst option seems to be Calendar Notify Agenda Status (https://play.google.com/store/apps/details?id=com.cliffcawley.calendarnotify&hl=en). I have been trying it for a few hours and it seems like an okay alternative (I'm not using the widget part of it, just the lock screen notifications).

I want to extract a gpg file (passphrase only, no key), with a Nexus 7.  It's just a gpg with a txt file inside.
How do I get it to the nexus 7 and then even if I can extract it, how do I get to it with a text editor?  I can scp it from my lan server to get it here (the n7).
I have the juicessh installed in the n7, I figured that's a good place to start, but how would I even do it from within juicessh- can I login from localhost? I tried loggin in to 127.0.0.1 but the ssh connection failed (perhaps not a surprise).
Seems like a simple thing but it's apparently not.
thanks

This would be on topic for [android.se], but as it stands, it's too broad for migration. For more information, see the [help].

Ok- I don't know how else to ask the question. Too broad?

I mean unless you want me to just narrow it to "I want to extract a gpg file (passphrase only, no key), with a Nexus 7. It's just a gpg with a txt file inside." And no other information?

...I took a closer look at the question and it's actually not too broad, but as written, it's a bit confusing. Organizing the text of the question to make it more to the point would make it easier to understand.

I have absolutely no idea how to make it more clear.

Samsung Galaxy S3 unable to power on after shutting off randomly
I am a problem with my Samsung Galaxy S3. There will be a time when the phone will shut off, and I won't be able to turn it on whatever I do (e.g. Pressing the power, home, or volume buttons). However, I tried stuff and this came to be a temporary solution. I would remove the battery from the phone for a few seconds and put it back again. Then I would plug in the phone and it would work again.
Nonetheless, it is only a temporary solution and the phone may turn off again sometime.
Can someone identify the problem?

Clearly the actions of reseating the battery and juicing it up, indicate a hardware issue related to the battery connections. Have you cleaned the contacts? Do you treat the device in such a way that it flexes so battery contacts are lost?

It seems that your phone have hardware problem . It loose the contact of power supply internally. May be there was damage in power IC.
If your phone is in warranty period give it to Samsung care otherwise take a help of local phone repairing center for cheap solution.

Annoying issue with my Gionee P5L
My phone's model is Gionee P5L. For the few days I am facing this stupid and annoying problem. I don't know why and how but I have multiple copies of the same apps in my phone... For example I have 2 facebook lite, 2 opera mini, 3 google settings, 2 play store. Can anyone let me know how to fix this ? Here are two screenshots.

Thanks in advance.

Is that a third party launcher?

no. default phone launcher

Motorola G2 - "erasing screen" and reboot (over and over)
I powered up my Moto G v2 and I received a notification about a system update, which I have accepted.
During the update process, came the Android logo with the message "error".
After a manual reboot, came the Android logo with the message "no command".
After some research on the Internet, I discovered that you can hold the Power Button, and then push the Volume UP button, and then a screen will appear to you, giving the options like "reboot the cellphone", "reboot to bootloader", "wipe cache/reset factory", and so on. So, I decided to use the last option. The screen has changed to an Android robot with a gear on the front and on the back, and suddenly, the phone has rebooted to the Motorola welcome screen, going to the same screen with the Android, the gears, and so on.
My questions are:
1 - What's going on exactly / why is this happening ?
2 - How can I fix this / what should I do ?
3 - With this current state, I believe that it is not possible to perform any interaction with Android utilities like "adb" and "flashboot", right?

While running the screen "erasing", press the "Volume Down" button, and after the reboot occasioned by the "loop", the Bootloader screen will appear, and then you can select the "Recovery" mode as usual, giving you  the normal menu screen (wipe cache, factory reset, mount /sys, update from SD card, update from ADB, and so on). With the last option, I was able to manually update the Android, using "adb" commands via terminal + using a update package (for example: http://androidhost.org/plvIU).

Samsung Galaxy Note 10.1 Bootloop?
I purchased a Samsung Galaxy Note 10.1 in 2013, GT-N8010, Android 4.4 and recently, I had a problem- when it loaded, it said Samsung Galaxy Note 10.1 and didn't load. I tried to factory reset it holding volumedown and power button, and it asked to go into ODIN mode- said a custom OS can damage the device etc. Then, on ODIN mode, it said:
ODIN MODE
PRODUCT NAME: GT-N8010
CUSTOM BINARY DOWNLOAD: No
CURRENT BINARY: SAMSUNG OFFICIAL
SYSTEM STATUS: Official
It froze and sometimes stopped when it was connected to my laptop. I then held both volume buttons and it went onto charging. I don't know what to do. I don't know why it said custom- I didn't tried to get a new android version or to root it.

Just flash a factory firmware via Odin. Nothing more you can do if that also fails.

Andy, how? I connected it to my laptop but it keeps saying installing drivers, or it disconnects momentarily.

You need to install appropriate driver (Samsung USB Driver for Mobile Phones) prior to connecting the device - the OS doesn't come with a usable driver.

Andy, my laptop won't let me do anything- it fails to install MTP

MTP isn't needed either. And if you mean your PC doesn't respond to anything from the tablet - even plugging it in while under Odin mode - fine, just borrow another PC.

I've tried but Windows 7 won't let me browse my files unless the driver is installed, and on Kies 3, it disconnects after failing.

Why are you still trying to browse files / use Kies? Sort out the driver problem and use Odin to end it once and for all.

I can't download the driver which is a problem- it says my device is not compatible. How else can I flash firmware to my device?

How "not compatible"? How did you try to install the driver? Use the "Samsung USB Driver for Mobile Phones" standalone package.

Yes, I got 'Samsung USB Driver for Mobile Phones' but then a notification says MTP failed, so I found a MTP driver online, but I cant install that.

MTP is not a problem. In download mode, plug the device into the PC. As long as Odin recognizes the device as COMxx, you can start flashing.

@AndyYan sorry I just left this, but I have a new PC and Odin doesn't say any more. Not even COMxx. It doesn't change screen. I took it to a few places to repair, but what else can I do?

Driver problem? Do you see a corresponding device in Device Manager in Windows?

@AndyYan nothing.

New PC? I'm at a loss too. I'm starting to think the tablet itself has a bad USB port...

@AndyYan I tried to flash firmware via ODIN and it did as https://www.kingoapp.com/root-tutorials/how-to-flash-samsung-stock-rom-via-odin.htm  expected, but when it rebooted, it is still on bootloop. The device was recognised by ODIN

Any help @AndyYan

Video errors across apps
I have an annoying problem. My Huawei honor 4c began some time ago to refuse to play videos on many different apps. I first noticed the problem on YouTube (I get the common "tap to try again" error, but the app immediately freezes). Then I realized I can't play videos on Google Photos or Facebook either. Peculiarly, I noticed I can't even record videos with the camera app.
All errors (that is, in all affected apps) are resolved with a reboot, but at some point (apparently random?) they appear again.
I haven't installed any new app or anything of the sort.
Any ideas?
The Android version is 4.2.2

I was going to say "Try switching players in dev settings" but can't remembe if it is on JB.

Can you clarify a bit - so that i could at least know where to look to see if it's in 4.2.2? Is "dev[ice] settings" a subgroup of "settings"? If so, then I can't see it anywhere

No, Its Development settings (where you can enable ADB and other stuff) it shows on the main settings menu AFTER you've tapped the build number in about phone 7-8 times

Found the Dev Settings, but no option to switch players. Thanks for the suggestion though

No problem. Huuhhhhh, tries factory reset? It can help. Back up yur stuff first, of course.

Microphone extremely quiet
For some time, my microphone is extremely quiet when doing things like making voice messages on WhatsApp or when calling someone. I searched the internet for a solution, but I couldn't find anything except for some apps which didn't work (or only worked in the app itself but outside did nothing).
Is there a config file with the microphone volume so I can adjust it myself or some script or so?
Wired headset microphone is also extremely quiet.

Information that could be relevant to this problem:
Samsung G900f (S5)
Android 6.0.1 / Cyanogenmod 13
Baseband version G900FXXU1BOD3

is your microphone fine for some apps say media player? meaning to ask if the volume is fine otherwise but low for say whatsapp 2. If yes, one could consider automation solution. Let me know

The volume is low for every app, but some voice recording apps have the option to set the microphone volume to a higher level, which makes the recording somewhat louder. So basically it's the same for everything.

Did you try the solution mentioned here https://forum.xda-developers.com/galaxy-s5/development/how-to-microphone-gain-increase-s5-t3190613

I know this is going to sound a little low tech, but have you tried blowing out or using a strong adhesive (like gorilla tape) to clean out the microphone holes? I've personally encountered the same issue caused by months of dust and pocket lint clogging up the microphone holes on a Note 4.

How to use Windows headset as Android call headset
I have a Windows PC with USB headset. I want to connect it to Android phone, so I can make calls using my computer's headset. Can I do so with usb, bluetooth, minijack or lan?

Yes, this is definitely possible - but not without special connective devices. You can actually use a variety off available connectors to extend comopatibility to the device, such as USB to 3.0 headphone adapter, and if your device will support the connection type, you could also use the MICROusb to USB 2\3.0 adapters.
Do a search online for one of the above mentioned devices, and learn more about them and your phones compatibility. You may also purchase of from almost any online electronic supply chains, as well as finding information regarding where to purchase one of the adapters locally.

Saying it's possible may provide some encouragement, but it isn't actually a solution.  Can you edit the answer to elaborate on how to accomplish that?  If the question is too ambiguous to answer specifically, that's a sign that it's too broad, and those questions are very hard to answer well.  With a little more rep, you will be able to post helpful hints and suggestions of directions to pursue as a comment.  Thanks.

Couple you provide me with a little guidance on how to best do this? I understand what you mean, but I am not quite sure how I could edit the current answer to contain any more specific steps on accomplishing what the questions asks. (For example, I have provided all the ways by which this could be accomplished, along with information regarding how to find the best route.)  I appreciate the feedback, I am just unsure about how exactly to utilize it.

Answers are better is they're "actionable", or at least specific enough that the reader can see what you're describing and how to adapt it to their case.  So a better answer would be to give a specific example, even if it isn't a precise fit.  (cont'd)

In addition to the general guidance, illustrate an example case.  Maybe a diagram and pictures of the components used for that case (whatever's needed to be clear and unambiguous).  Then the reader can find the specific adapters for their hardware.  On an ambiguous question, though, you can easily put in a lot of work only to find out that it doesn't address what the question's author was thinking about.  It's better to get clarification from the author first.

How to make Gboard (Google Keyboard) look like the 4.4 version?
With the advent of Android 5.0, Google has switched to a new design (Material) for their keyboard.

Google play voucher option displayed for in-app upgrade but not valid after all
I just wanted to buy the pro version of an Android app (Memrise). The Pro version is not a separate app but an in-app upgrade function.
So I chose my preferred subscription, and the usual Play Store dialogue popped up and asked me to choose a payment option. Since I got a 50 Euro voucher I chose the option "Gutschein einlösen" ("redeem a voucher" or something similar in English). So I typed in the code and my payment validations and the cash transferred to my account. But before I was able to complete the transaction the Google Play Store told me, that a voucher is not a valid option to pay the app upgrade.
So why was there the voucher option in the first place if it is not a valid option? I have no use for other apps/music and stuff except for that specific upgrade. Is there a way to get the upgrade / the money back anyway or are the 50 Euro just gone?

is there a more proper stack exchange category to ask that question?

Not very sure, maybe you can try [android.se]?

Yes. [android.se] or [webapps.se]

Is it required to unlock the bootloader to root (normally)?
So, a long time ago I rooted my device using a Windows app called KingoRoot, and after that my tablet didn't boot. The exact same thing happened with my other device. I did not unlock the bootloader because I didn't even know what it was. The tablet will sorta boot but the OS just refuses to load. Is this device bricked? Is it fixable? If it's any help the device is a Thomson QM-736 running Android 4.4 KitKat. I also have both the ADB and Fastboot installed on my PC, however the tablet will not connect (I assume the charging port is dead) so I don't actually know how those will be helpful. Thanks in advance.

To answer your title, no you don't need to unlock bootloader to root your android device. I rooted my device two months ago, with bootloader still locked.
Unlocking bootloader lets you change to which operating system is launched, install/remove operating systems in your device, etc. While rooting gives you root/admin right INSIDE the operating system (i.e. after the OS has been launched), via an exploit. I also used KingRoot, but I installed the KingRoot apk on my phone and let it do the trick. Had ADB and Fastboot configured on my computer, in case it didn't go right, but I didn't needed them.
Remember, unlocking bootloader will wipe all the user content from your phone, like a factory reset. Plus it will wipe the TA partition (which holds DRM keys that lets you use manufacturer's proprietary technology).
In your case, it seems the rooting process wasn't successful. So you can either unlock the bootloader and then reinstall the android operating system (or install a custom version/fork of android), or perhaps you can get your manufacturer's stock OS and install it using some tool that does not require you to unlock the bootloader. Can't say whether it's available for your device/manufacturer though, but I got XperiaFirm and the android image in (.ftf format) ready for myself if my root failed.

Some devices need boot loader to be unlocked even for rooting. Similarly, unlocking bootloader usually wipes data buy not always. Example Honor 6. You may like to edit your answer suitably

Addition: the section about TA partition and DRM only rings true for (newer) Sony devices.

Small question: How do I unlock the bootloader or reinstall Android if the device won't boot and the buttons are gone?

Some apps' notifications disappear after half a second
I have an Acer T07 (aka Liquid Zest 4G aka z528) with Android 6.0. I got it for Christmas so I did not have the time to tweak it for now !
Whenever I recieve an SMS, a notification does show up, and then disappears after half a second. This is particularily annoying since I am not always looking at my phone and when I check it I see no notification. Then, I open the SMS app (currently using Pulse SMS but the same happened with Textra and basically any alternative SMS app - tried a lot of them) and see unread messages I was not aware of. However this problem doesn't happen with the stock SMS app.
I thought this was just with SMSs but from time to time the phone vibrates and when I turn on the screen to see what's hapening, I see nothing - which is certainly because a notification arrived just to immediately disappear.
I don't have a list of the application that do this mostly because I never see those notifications. Apart from SMS, I use very few apps that generate notifications (no social networks or similar apps) so it's hard to tell how many apps have the problem and what they have in common.
I found no one with the same problem by googling it and neither by searching this SE.
Any help on how to fix this weird problem is highly appreciated !
Thanks :)
EDIT : I found out that Discord app does it as well. I also found out that some notifications don't even show up, but just make the phone vibrate without letting me know at all what app it comes from.

Android Tethering Turns off straight away
From time to time, the tethering on my Nexus 6P, running Android 7.1.1, turns itself off for no reason. It can then take 5 or 6 attempts for it to turn back on.

This has nothing to do with a computer, and is off topic. You correctly tagged your question as android, please click on it and read the description :)

Do you have given permission to use data(internet) for the System app named 'Android System'?

If your Nexus 6P is rooted:

Install Build Prop Editor app from the Play Store and launch it.
Change net.tethering.noprovisioning=true
Install Terminal Emulator app from the Play Store and launch it.
In Terminal Emulator, enter the following code sequentially:

Unlocking my sony xperia M5 DUAL's bootloader
Can anybody explain me how I could unlock the bootloader of my Sony's Xperia M5? Because in your developer website, there's not my phone in your unlockable bootloader list. And when I type this code into my dialpad (##7378423##), I see that it's unlockable.
I have already tried to search the way to but I can't until now.
Please help me if someone knows how to unlock it

For all Xperia devices, use Flash tools to unlock the bootloader (if it can be).

"your developer website" What site is that?

I found some info here. I've copied it below

1.In http://developer.sonymobile.com/unlockbootloader/ choose Sony Xperia M2.
  2.Submit Email
  3.Submit IMEI
  4.And unlock bootloader with intruction.
  You get the code? Then we continue.
  Download the latest version here or Flashtool http://www.flashtool.net/downloads.php
After installation, go the path C: \ Users \ username \ .flashTool \ registeredDevices here and create a folder with the code-name of your machine (you can find out if flashtool click on BLU and see where in the log are in line «Current device» for example, in line 09/045/2015 23:45:08 - INFO - Current device: C2104 - AB100C2DE3 - 1272-4136_R5B - 1269-5420_15.3.A.1.17 - WORLD-a_15.3.A.1.17 code machine will AB100C2DE3. Code which will write your name and location).
  Later in this folder, create a text file and name it «ulcode» (without the quotes). Open, and in it write your unlock code, that you have on the site Sony.
  Save. Write code very carefully.
Now open flashtool and press the BLU. If everything is correct, in line you should write your code, pressing unlock. All should be ready to unlock.

Yes, it is for the M5, not just the M3, at least it says in that post In the title, i sadly can't test it for you as I don't own one

Does nexus 5 support chromecast 2?
I bought Nexus 5 from India 3 years back.
Now I have chromecast 2 from France.
But when i tries to connect, my nexus says no compatible devices found nearby.
I tries connecting with Google Home application. Though that also i am not able to connect. It says check you T for a code but there is not code displayed on my TV (I checked my TV and I was on the right HDMI port)
Can anyone help guide me. What to do?

It seems like your chromecast is not setup properly.
Make sure you connect the chromecast through HDMI and also power it using the usb port at the same time. If you see the chromecast installation screen on your TV, then you can use Google Home to install it.
Also, the USB port on your tv is likely not to supply any power.

Yes, I connected to USB power in the wall and HDMI to TV. and I see white light blinking but i cant see installation screen on TV

The chromecast could be damaged. Try it on a different tv to verify.

Xiaomi Redmi Note 3 keeps restarting as mad when charging (until airplane mode)
My Xiaomi Redmi Note 3 keeps restarting as mad when I charge it, but when the airplane mode is turned on, it tends to behave.
I suppose it's not a hardware issue, but something more complicated. I suppose the device tries to upgrade software when charging and it fails which causes software (it kept asking me about manual updates, each time I tried to update, it failed). My current MIU version is 6.1.14 beta, I have no idea how outdated it is. That misbehaviour makes it impossible to charge phone, because each restart eats more power than it was charged in the meantime, until airplane mode, which renders phone useless when charging.
Is there anything that can be done to save the phone, or it simply belongs to trash bin?
The phone is relatively new, it was used by about half a year.

Why not disable the auto update ?

@esQmo I can't find an option to disable miui auto updates. I can only disable google store updates, but they don't seem to be an issue.

In the About device section > Update ?

Your phone is in beta rom.Try to flash latest global stable rom by edl mode,maybe this may solve the issue.

How to do that? Is it possible without loosing data?

No, your all data will be erased,including internal storage.And you have to do this by a pc using mi flash tool.

Internal memory explanation
I have a Moto E 2º Gen, 8gb internal memory.
If we substract the Android OS requirements, i'm left with 4.98 Gb, which appears as available internal memory.
It shows 4.11Gb used memory, however, below the phone shows the following:
Apps: 2.21 GB
Images: 8 KB
Videos: 0 B
Audio: 120 KB
Other: 99.98 MB
Cache: 1.99 MB
which adds up  close to 3.2GB, so: 3.2GB != 4.11GB. What's going on with those missing 900MB?
Another hints that troubles me comes from plugging the phone to a PC via USB:
Internal memory shows only 342MB available, and the rest all occupied, but when i access the internal files, all files togheter only weigh 224MB!!, and there are no hidden folders.
Can someone explain why this happens, and what are the REAL numbers to take into account.
How could it be that there are hidden files that i can't see even with Windows option "see hidden files" activated?
This is a specific question, but i've seen this in other android devices, so maybe the answer could be in the OS and the way it manages data, more than a device specific issue. Maybe some internal OS memory is not being shown by the device?

I'll try to be straightforward. My answer won't give you a formula explaining why this exact amount of memory is missing from your phone, but it'll hopefully give you an insight about where it's being used and ... why it's needed.
Think of a storage as a copybook, in each page you can store certain amount of data, the technical term for that is a block and its size varies from a system (hardware + software) to another.
Now imagine that each of your files is stored in one page of that copy book, let's say you've got 24 pages and 14 files. You might think that the remaining pages are 10 pages (24 - 14 = 10) but that's not right.
You see, in order for your system to know the location of each file it has to store somewhere the location of each single file, it's like an index containing the number of the page for each file. This index itself might take some pages from your copybook and so does the index used by a real file storage system (FAT, FAT32, NTFS...)
This is probably where your missing storage is being used. Just check what file system is implemented on your phone, make some research and you'll get some more in depth explanations (may be some formula along the way).
Cheers!

Read audio from USB OTG
I have a lot of music files. Far more from what my SD card + internal memory could support even if they had no apps, pictures and whatnot stored into.
I have a 128Go USB stick where I store all my music so I can listen to it on any device. However, this does not work with my Android 6.0 phone.
I mean, I can plug the stick on the device with the cable, then click onto the "USB drive" notification to see the files and then play the file I want. Problem: I want to listen to music through a proper player, which goes onto the next song when one is finished and let me browse my music in an intuitive manner.
So far I was unable to find any player that would detect music on my USB stick. I think I understood now the problem comes from OTG itself - which is made for using a DAC more than a USB stick or to store files more than play them - but I wonder if there isn't some kind of trick or workaround to get, for example, my phone to detect my USB stick as an SD card, or to make it treat the stick as internal memory (which is possible with SD cards).
My phone is not rooted for now (haven't got the time to investigate much on this) by I do have a custom recovery (TWRP) if that can help. If rooting is necessary I'll dig more into it.
Thanks for your help !

Well, finally, I found an app that can read music from an USB stick.
ES File Explorer
It is a file eplorer which:
1) detects USB sticks
2) comes with a simple music player with basic functions
3) can create a playlist from a specified folder
4) can do this with USB folders
While the player in itself is not exactly the most advanced one (it won't detect id3 tags on USB files, doesn't sort songs by Artist, Album or whatever else than alphabetical order) nor the most beautiful, it has all I need for listening music in the subway (which was my main goal here) i.e. making a playlist from my music folder and being able to shuffle it.
Hope it helps people who had the same problem as me.
Edit
This player has some problems. It crashes, don't detect the stick sometimes and often goes as far as restarting my phone. It does the job, but it does not do it well and the user experience is unpleasant. Therefore, if anybody has a better suggestion, please write an answer !

Okay so this is a pretty easy method, however it requires root. Luckily you have TWRP installed so all you have to do is flash SuperSU.zip (google for it "supersu xda") in TWRP. Once rebooted, grab a terminal emulator.

Type su
Then mkdir /sdcard/somemusic
Then mount -o bind /path/to/otg /sdcard/some music

You could also try StickMount in the PlayStore but I do not know if this works, it also requires root.

Thank you for your answer, I guess rooting is inevitable! The problem is that flashing superSU in my TWRP doesn't work but I'm trying to solve this with some people on XDA. I'm going to try your solutions as soon as I have managed to root my phone.

@Ctouw what device?

Acer T07 aka Acer Liquid Zest 4G.

@Ctouw Did you get it rooted and TWRP installed? This YouTube video looks easy to do: https://m.youtube.com/watch?v=ukkzrlQ7yoM

Well the installer was kind of bugged for me: I meticulously said no to all crapware and ended up having all but OCR. Anyway I have eventually found an app that does what I was looking for.

There's a solution over at XDA:
Simply open terminal and type:
su
sm set-force-adoptable true

If you can live with playing all the tracks of an album in your preferred predetermine order or a set of tracks like in a playlist, you could concatenate several audio tracks(files) to create single audio file.
Then, you could play the created audio file from an OTG USB drive with any audio/media app as your created file will look like a single file, but it will contain all the concatenated songs. As an example, if you have 100 tracks you could organize them into 5 or ten files. A work-around.

Changing device configuration to display non-circular launcher icons
According to this article, an Android device's "system framework decides whether or not to return either the regular icon or the round icon to the launcher."  "When a launcher requests an app icon, the framework returns either android:icon or android:roundIcon, depending on the device build configuration."
Is it possible to alter the device build configuration to change the default icon display to non-circular?
I'm on a stock, non-rooted Nexus 5X.

For a non-rooted device, it's not possible as far as I've seen, as it's totally under control of OEM as implied in this Android developers documentation. But otherwise, it's possible if one can edit config with the value of config_useRoundIcon to false.
Just for experimenting, you can decompile the framework-res.apk and change the above-mentioned value in bools.txt and recompile the apk and push the apk into the device.

How can i Bypass the owners Google account verification on Android v10
My friend bought a used LG Android v10 T-Mobile phone and she factory reset it immediately because she didn't know the screen lock password. Unaware of the new security lock option for Google account. It says connect to Wi-Fi. Then press next. It says 'checking connection' and  'verifying Google account'. Then it directs me to the sign in requirement page for the phone set up and asks for my e-mail address.
When I put my e-mail and password in, Google security account verification calls phone to give code. I then have to type in the 6 digit code provided. It checks information and accepts my account info but before next step it redirects me to "please sign in using the owners account that was previously synced to device" and I don't have any way of knowing a name or e-mail of original owner.
Is there a way for me to bypass this Google security verification so I can use this phone?

i hope this helps. check 2nd answer

Try contacting the previous owner of the phone and see if you can have them set a temporary password to get through it.

Can I get Apex Launcher's scrolling background to work on EMUI 4.1?
I got my new Honor 8 this past Monday, and after extensive tweaking (including hair pulling and uttering of words not approriate in respectable company), I got it to work and look the way I want it to, except for one thing. The scrolling background of Apex Launcher simply refuses to work. I've browsed through the system settings and the Apex settings until I've gone blind. I've tried to change the background setting of Apex to non-scrolling, restarting, changing it back to scrolling and restarting again, but I simply can't find a way to get this working. Is there a way?
I'm using Wallpaper Changer as live background, but I've tried disabling it, and instead using EMUI's native function to randomly change the background image, but this makes no difference. I've also tried setting Wallpaper Changer to use static background rather than live background. This also makes no difference. The image is cropped to the physical screen resolution (1080x1920) and the leftmost part of it shown on all screens.
For example, this image

is shown like this, regardless of which screen I'm on

I've rooted, and because of issues with TWRP and SuperSU on EMUI 5.0, I won't upgrade until those are resolved.
I'm not in any way affilated with with any software mentioned above, I'm simply a user. The images above have been created by myself, and you are free to download and use them as you see fit.
UPDATE: This suddenly started working. I don't know what fixed it, so I don't think this can be classified as an answer. It started working after I shut down to replace the SIM, because the transfer of my number from my old carrier to my new one had just been done. After booting up again, the scrolling background was working. As far as I can remember, I had changed no settings since I last rebooted. I did receive an update to Wallpaper Changer, but that came after the scrolling background had already started working, and the changelog only mentions adding the ability to darken the wallpaper. A mystery, but I'll leave it at that, unless someone has any ideas about what has happened here.

Can't say specifically about the launcher but bear in mind that Huawei tweaks the OS very heavily to the extent some apps just don't behave the way they are supposed to- especially those interacting with UI. Not surprising. IMO, options are use a launcher that suits the phone you, or browse Chinese forums for a modded launcher and use that at your risk

@beeshyams I'm aware of Huawei tweaking the OS, and I decided to go with the Honor anyway. And considering that I got it to work the way I want, apart from the scrolling bg, I don't regret it. And with the options you presented, I will live with the non-scrolling bg.

Earlier device of mine was Honor 6, and it had problems with Xposed framework too involving UI- suggest research that if you are going to use Xposed

@beeshyams I've tried Xposed in the past, both on my S3 and my S5, but I've never found any modules for which I actually had any real use, so I hadn't even considered trying it now. Still, it's good to know that it may be problematic, and that I need to properly reasearch it if I do decide to use it. Thanks.

Android tablet bootup very slow
Earlier today, I was using my tablet. It ran out of battery so I charged it.
Then my tablet got stuck at the logo screen. I booted into recovery and cleared the /cache partition.
Finally, I realized that the tablet was not stuck, it was taking a very long time to boot!
I wait at the boot screen for about 3 minutes, then it changes to the loading image (which for me is a lot of moving tiles).
Why does it take so long all of a sudden?
Specs:

Tablet: Kobo Arc original White 32GB version
Processor: TI OMAP4470
RAM: 1GB
Graphics card: PowerVR

Did you install any system tweaks like Xposed? I am finding them slowing down Android booting. Even more different versions of Xposed cause significantly variable slowdown effect.

@iBug To avoid bricking it (like my previous 2 tablets), I haven't customized anything.

That's over-cautious. I often modify /system and /data after a backup. It's safe if you only touch the ext4 partitions after backing up. As long as you don't touch anything else there's nothing to worry about.

LG G4 Problem with "camera unfortunately stopped working"
Recently my camera on my LG G4 has been having some issues and is not working at all.
When opening the camera app either front or rear there is just a black screen and after a moment the message "camera unfortunately stopped working" and the app is closed. Also I have checked that the flashlight is not working but that must be related to the camera problem I guess.
It is not the first time it happens. Sometime ago I had the same problem for about two weeks but the problem magically solved itself. But know it reappeared when I tried to open the camera through the locked screen menu while having another camera app which might be unrelated but I am not an expert.
I have tried several usual methods to solve the problem:

Rebooted the phone;
Deleted Cache (Both camera app and gallery);
Deleted App Data;
Tried a third party app;
Factory Reset;

Nothing Worked!
I have know tried to use adb and android studio to see what kind of errors are issued and what I got was this:

Other informations about the phone is that it is not rooted and has no custom ROM installed by me.
I really hope there is someone who can help me with this because this camera would serve me well!

I am exactly in the same situation with my LG G4. I tried:

rebooting the phone
deleting cache
deleting app data
doing a factory reset
removing the camera and installing a brand new one bought in a phone devices store and STILL NOT WORKING. I wonder if you could finally solve the issue. Thanks for sharing.

Turns out that my problem was in the hardware. There was some kind of power supply, in the phone motherboard, that was broken. Basically, the people at the repair shop substituted the motherboard, which is almost the same as a substituting the phone.
There are a lot of possibilities, but I hope that helps somehow. @nuantagi

Warning message after doing backup in TWRP on Honor 8 (FRD-L09)
When I do a backup in TWRP on my Honor 8 (FRD-L09), it invariably end with a message saying that it failed to unmount /system due to device or resource being busy. The header still says that the backup is complete, and that it was successful.
In case it makes a difference, I'm running FRD-L09C432B131, which is EMUI 4.1, Android 6.0. Kernel is 3.10.94 from 11 October 2016. This is what was installed on the phone when I got it. I got the bootloader unlock code from Huawei, by registering and applying for it. TWRP is 3.0.2-0 downloaded from here and flashed using fastboot on Windows 10.
Here's a photo of TWRP after finishing the backup:

Need I worry about this?

Can you boot properly after this? If yes, no worries.

To be more sure, reboot into recovery again and see if this warning persists (it shouldn't).

@AndyYan I'll try that later. Right now I'm off to bed. Thanks again.

@AndyYan I just tested. Did a backup. Then I tried to manually unmount /system, both from the TWRP menu and from its built-in terminal. Both failed with the same message. Then I rebooted, selecting Recovery from TWRP's menu. When it came back up, /system had not been mounted, and no error/warning messages appeared. And rebooting the system after this works normally.

It's quite obvious that the recovery itself is buggy. Not unexpected for Kirin devices... I'll post the above as an answer.

To isolate the problem, 1) reboot into Android and see if it does so properly, and 2) reboot back into recovery and do the same operations.
Judging from your response on the 2 points, it seems your recovery is at fault here. Not unmounting /system is usually not a problem: that step is done as a safety precaution to prevent accidental modification to /system when not flashing. As long as you don't do that yourself you should be fine.

How to keep text and icons at normal size but use tablet mode?
Just rooted my tablet the other day. Running Android 4.1.1. This is stock Android except for a different launcher.
My tablet's resolution is 1280x800. It was running with a density of 213 for several years. Recently I wanted to try tablet mode, so I shrank it to 170.
I'm perfectly happy with this setup, but would like to know if it is possible to make the icons on the launcher (and other text) the original size, while forcing the UI to tablet mode.

Try finding some app for that, there was some xposed module I can't remember the name. Of course that changing of denisty will make icons and text and everything bigger/smaller..

Get rooted, install Xposed framework and then this module called App Settings. Lets you tweak density, font size and a bunch of other properties on a per-app basis.
Disclaimer: rooting and using Xposed comes with their own risks and it's your own responsibility to do backups.

what is the advantage of using the GPU rendering options in Android?
Here is a screenshot:

Will it speed up my device to enable the two GPU options?

Force GPU rendering and Disable HW overlays are discussed in Can anyone explain all these Developer Options?, which see. The former basically makes no difference unless you have a very old phone, because all the 2D canvas rendering is done on the GPU on most phones anyway.
The latter won't make any difference in speed but will probably use more battery power if you turn it on. Many phones have a hardware overlay built into the display controller. This is a simpler piece of hardware than the GPU, but it can only do simpler operations. In the simple screen composition cases, the hardware overlay is used, and this uses less power than doing these simple operations on the GPU. Only in more complex cases (such as while window animations are happening) does the full power of the GPU need to be used. Turning this option on will make the phone use the GPU all the time, even in easy cases, which burns more battery power. It's only useful for system integrators to debug Android on their hardware.
Show GPU view updates and Profile GPU rendering are useful for app developers to learn how efficiently their apps are using the GPU. They make extra information available, which costs a little power (but probably not enough for you to notice). They won't make anything go faster.

How can I get the Samsung settings menu on a non Samsung Phone (Android)
Just got a new phone for work, the trouble is that I am finding it really difficult to use and navigate the Android 6.0 settings menu on it as I am used to the one from Samsung. Is there any way I get the Samsung version of the settings menu on my new work phone? (Blu R1 HD)

This is probably not possible, or at the very least rather difficult. TouchWiz, which is Samsung's custom Android UI "skin", is not available to download and install on the device of your choosing.
There might be a way to get it running on a rooted phone but I'm guessing that's not something you want to attempt, especially if it's a work phone.
The only other possibility is to look into 3rd party launchers such as Nova but I don't know which, if any, affect the settings drawer.

How to block incoming advertisement sms from senders with no visible phone number?
I get spam ad messages from a few companies regularly on my phone. And when I try to block them using the option given on the messaging application a custom message says that the number is invalid and cannot be blocked. So, how to stop such messages sent by unknown numbers?

This may work for you- it does for me. 1. create a contact for this purpose with spurious number 2.Use Textra messaging app and from People in Conversation>add contact add to the contact created in 1 3. Blacklist it

"create a contact for this purpose with spurious number". The problem is that the sender has no visible number! @beeshyams

Just give it any number- like 999999, which isn't valid. Then you add this sms contact as pager/ home or any other option

@beeshyams Textra doesn't work (isn't compatible) on my Samsung tab 4. Any other option?

Sorry, but I do remember that this question was asked before and answered- suggest you search this site thoroughly

Does turning off ( Wap Push Message's ) in the default messaging app work  ?

@NoobFood What does that do? And how to turn off Wap Push Message? I have a Samsung device (Tab 4).

Wap Push messages allow websites to send messages through the internet or PUSH them through, I think Facebook has a push notifications feature like this ! ... You can turn it off by going into the default messaging applications settings and unselecting Allow Wap Push messages

Try this SMS Organizer app.
Apart from a host of other features, this app lets you set 'rules'. For example, you can set a rule to auto delete any message when the sender's phone number/contact name contains a certain sequence.

If you are unsure about deleting, you can also set the rule to move the sms to a folder (This app also lets you create folders for sms), say a spam folder

No "None" Option For Lockcreen
When I go to disable my lockscreen, there is no "none" option. This is really annoying as I am unable to get a custom lockscreen with the stock lockscreen overlapping with it. I've looked through multiple forums and tried all the suggested solutions but they don't work. The none option isn't even greyed out like people have reported, it's just not there. I'm running android 6.0.1 on an LG X Power.

Use this video as it seems exactly like your problem, try it then comment if it works https://www.youtube.com/embed/LV_7APlAvvc
So, basically what you need to do is :-

Go to settings and remove your pin/passwords if you have any.
Go to `settings>security' and at the bottom of the page you should see "clear credentials" tap on it and clear your credentials.

3 Now go back to lock screen settings settings and you should see the "None" option waiting there or you.

Nope. Didn't work. Still doesn't have the option greyed out or even there. The thing is that when I clear my credentials, the option is still there not greyed so I can click it multiple times. Does that help at all?

I dont think so, Maybe it is how it is. Dunno man.

mp4 video will no longer play
I have an mp4 video on my Dropbox. I was able to watch it earlier with the Dropbox app, but now it asks me whether I want to view it with the Photos app or Video Player... and neither appear to work.
I have tried saving the video to my device but still no luck. I am able to watch the video through VLC player with no issues but I am trying to post the video to Instagram, and Instagram can't understand it either.
I can also view the video on my iPad... and I've tried force stopping my Android apps and restarting my phone but still no luck

Sounds like some problem with codecs maybe. Did you  recived android update near time when videos become unplayable? Do you use custom rom?

I realised the problem was there because the video was 1200 x 1200 — I'd exported it from Photoshop — I then resized to 600 x 600 and then it seemed okay, and could post it to Instagram

Try using VLC, it plays most videos other players cannot and has a good interface. However, if this still doesn't work, try using Video Converter, Compressor and select the file then change it to an MP4 (I know it's already MP4, but this may fix any issues).
VLC: https://play.google.com/store/apps/details?id=org.videolan.vlc&hl=en
Video Converter, Compressor: https://play.google.com/store/apps/details?id=com.xvideostudio.videocompress

thanks, I'd tried VLC player as per my post but had also tried the converter / compressor to no avail unfortunately!

That's a shame, but I'm glad to see it works now through Photoshop!

Contacts, asking to Block or add to contacts
I recently lost my phone and reloaded WhatsApp on my new phone. Now, every time when I receive a message from a contact, it asks whether it should block or add to contacts. This does not happen when I send messages to my contacts.

Do you have given permission to read contacts, for WhatsApp?

Which Android version of your phone?

If Android Version Marshmallow or above, you have to give permission.

Go to Settings
Apps
Whatsapp
Tap on Permissions
On Contacts permission and check.

Twitter on Android, missing tweets from Timeline
I recently changed my phone, Twitter app was downloaded, now I find that hours of tweets don't appear on my Timeline, if for e.g., I was on 8 hrs ago it wont show tweets since then till about 10 minutes ago, there is no "show more" anymore where it would open up and show tweets that were posted during that period.

I have not used this app in some time, so I'm working from memory. The Twitter app for Android is lightweight, and only retrieves a known quantity of back tweets. (If I recall correctly, 200). If you follow high-volume users, this will fill up quickly, and ignore everything between. Maybe try a third party Twitter app?

I just tried this by installing the Twitter app on a device and comparing to my timeline on the web. There is a distinct gap between 1h ago and 11h ago, in the app, so it has skipped presenting 10h of tweets. I estimate the break after about the most current 200, as I said before.

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

How to automatically reconnect VPN on network change?
I'm using a VPN service, but so far I've only been using it on my computer. Now I'd like to have it on my phone as well. The service I use allow up to four simultaneous connections, so that isn't an issue. They don't have their own client for Android, but they do make config files available for download and use with any client that supports OpenVPN. I've tried OpenVPN Connect, and it works quite well. However, whenever I switch between networks, for example when I lose my home WiFi on leaving my home, or when switching between public WiFis, it doesn't reconnect, so I have to remember to actively disconnect and reconnect.
I've tried setting up a macro in MacroDroid to automatically close OpenVPN Connect, wait for a few seconds, then reopen OpenVPN Connect, but all that does, is bring up the login screen, and I still have to manually click Connect.
My phone is rooted, and in case it matters, it's a Honor 8, FRD-L09 running EMUI 4.1. I'm not going to upgrade to 5.0 at this time, as TWRP and SuperSU have been reported not to be compatible with the EMUI 5.0 kernel. Other than that, I'm open to suggestions. I'm not afraid to play with shell scripts, as long as I have some understanding of what the script does, and with this, I have no idea how to implement it in a shell script, so if if you have such a solution, please also explain what it actually does.
EDIT: OpenVPN Connect has the ability to create shortcuts to disconnect and connect on the homescreen. I'm assuming that these shortcuts just pass arguments to the executable, telling it what to do, and what config file to use. If I knew how to find what arguments the shortcuts pass, I'd likely be able to write a shell script that I could then call from MacroDroid upon network change.

@AndyYan was mentioning shadowsocks  as an option to keep VPN persitent across disconnects.  Not sure of it is the same one with that name on Play Store. He would respond I suppose since he is tagged ( else please search chat room where he elaborated on this in a comment to me and you can follow up on that )

@beeshyams Unfortunately no. Apparently they've done some work on this, because last time I tested it, a few months ago, it didn't even try to reconnect. Now it does seem to work when going from WiFi to LTE or 3G, but still not when going from LTE/3G to WiFi.

This may give you some pointers

@beeshyams That one brought a nostalgic to my eye. I used to be the proud owner of a N900. The last non-Android I had... Anyway, I'll look into that thread. Thanks.

Does MacroDroid let you send an Intent with extra parameters? I do this with OpenVPN Connect via Tasker, so if you can do that you might be able to use something similar. Here's how mine is configured in Tasker.

@eldarerathis Yes, MacroDroid can send intents, though it's marked as experimental, and I had to enable experimental features in the settings. I just tried this, and it does the same as the macro I tried earlier, i.e. it pulls up the connection display of OpenVPN Connect, and I need to manually click the connect button. Screenshot of the macro and Screenshot of the intent. Some ideas: Did I misconfigure the trigger, should I add something to Data and is VIEW really the right action?

I suggest you ask in Macrodroid forums ( accessible from within app) , posting the screen shots. The developer is usually fast in responding

@beeshyams Will do. Thanks for the tip. While not strictly a requirement to do this with MacroDroid, it'd be a very welcome solution.

VIEW is the correct action, and you shouldn't need anything for Data (unless MacroDroid somehow sends the Intent differently than Tasker). You have the name of your profile specified in the Extra field, correct? Is that the part that's redacted by the red rectangle? And you have the latest version of OpenVPN Connect installed (1.1.17)?

@eldarerathis Yes, the profile name is under the  red rectangle. I tried putting it on one line, with an equals sign, like in the link you posted, but since MacroDroid has two lines, one named Extra name and the other Extra parameter, I assumed that's the correct way. I have 1.1.17. Build 76 to be exact. I've had more pressing activities than this, so I've not played with it since I posted the screenshots, nor have I asked on the MD forum yet, as suggested by beeshyams, but hopefully I'll have the time this evening.

Nougat has VPN on built in. Tested with WiFi and mobile and it works fine

@beeshyams I'm aware of that. However, the versions I have access to (EMUI 5.0 for Honor 8 and Lineage for Galaxy S3 and S5) only support PPTP and IPSec, and the VPN service I use only runs over SSL. As far as I know, PPTP has been considered insecure for several years. I don't know enough about IPSec to reject or embrace it, but since my VPN service of choice doesn't support it, I don't use it. Thanks for the input though.

This seems to have been caused by either a bug or an oversight by the app developer, and it sorted itself after an update. Just make sure the OpenVPN client is recent.
Also, the following settings are worth checking.
Reconnect on reboot. Enable it unless you want to manually decide when to OpenVPN and when not to.
Seamless tunnel. Enabling it blocks all internet traffic while the VPN is (re)-connection, to avoid leaking your real IP.
Connction timeout. How long to try re-acquiring the connection if it is lost. Set this to CONTINOUSLY RETRY to keep trying until a connection is established. If a timeout is set, and a connection has not been established before it runs out, OpenVPN Connect will exit, and the connection will be unblocked, to let you connect unprotected until you manually restart OpenVPN Connect.
Moreover, keep in mind, that reconnect on reboot only works if OpenVPN Connect is connected when you initiate the reboot. If you manually disconnected or if you lost the connection, you need to manually reconnect after rebooting.

Try to check keeplive option in your server and client config. For example "keepalive 5 40" will send test packet every 5 seconds, and will reconnect after 40 seconds. So when you switched from Wifi to mobile internet it will reconnect after 40 sec. Of course you can use less options, 1 10...

This sorted itself out with some update of the OpenVPN client for Android, and now works flawlessly without the need for stuff like MacroDroid or Tasker. Moreover, I'm using a commercial VPN service, hence I do not have access to the server's config. I'm upvoting your answer, but I'm not accepting it, since I can't really try it out.

Have you checked the Settings in OpenVPN Connect (in the burger menu, top left)? There is an option to reconnect automatically and an option to block connectivity when the VPN is offline.
However I have not tried it with multiple connections.

I had tried all options about automatic connection, and they did work when coming back to the same network I had lost, but not when moving to a different network, such as moving between mobile and WiFi or between different WiFi:s. However, it sorted itself out after an update, as I also pointed out in the comment to @DavidK's answer as of Dec 6 2017. +1 because the suggestion is sound, but I can't accept because the problem was most likely a bug or an oversight by the app developer, and it has been fixed.

@DuaneDibbley It's OK, I'm happy it's a valid suggestion and it might help someone else. Thank you. Since you have found a solution, you could maybe write your own answer and accept it.
