Change orientation in androidx86
How can I fully rotate my screen and not only resize it like in the picture?
In already tried several rotation apps in the play store. I tried via root shell the commands: wm size, settings put system accelerometer_rotation 0 and settings put system user_rotation 0 both are working fine on my phone, but not on my tablet.

You should try some rotation control app from play store, like Rotation Control which can rotate the screen in any direction you want (like reverse portrait)
     But you should also note that it's not possible with every app, because maybe the layout is not provided or the layout is forced to be in portrait mode, in that case no app can help you.
    There ain't much apps available specifically for xxhdpi & xxxhdpi screens and so you're not left with much choice but to work with the way it is....

@Abochur As OP puts, "How can I fully rotate my screen and not only resize it like in the picture?" - what I understand from this is, the situation shown in the picture is what OP has right now, and is not what he wanted. I'd say this answer got it right.

@Abochur On Android-x86 it works differently, since 1) most PCs have a built-in keyboard which is recognized, and Android by default will disable rotation with a keyboard connected (even if auto-rotation is enabled), and 2) many PCs don't have a sensor to detect auto-rotation with in the first place.

That is exactly what I get when I use such a rotation app you mention. I also tried via shell WM size, and settings put system user_rotation.

@AndyYan my tablet, has a rotation  sensor. It works on windows but it seems that android does not recognize it. I also detached the keyboard several times to see if that helps but it does not unfortunately.

Android x86 is not a perfect os for PCs, it has a lot of glitches and this is one of many...

@DhrubaJyotiSaikia so there is no way that this works? Should o try something like RemixOS (but i think it has been discontinued) or PheonixOS (its not very good).

If you ask for my suggestion, then I'd say you should go with Linux, that's pretty amazing, and it'll definitely allow you to use your device to its full potential...

Rotation Control works only properly if in init.sh has_sensors is set to true

I did not found any solution. I installed the new PhoenixOS. It works good, and the orientation sensor works too. Maybe we will find a solution for android x86 soon.

In latest version of Android x86_64 8.1 Screen is rotating normally if you select in Grub ... > Advanced Options ... > Vulkan Support

I face same problem on chuwi Hi10 x.
Reason was if your tablet orientation sensor is not recognized
Or defined in Android it forces screen in one orientation
To solve this
Open init.sh file which in device root /etc/init.sh
Find the following line
"has_sensors = false" and make it = true
this tell android that you have orientation sensor even if it actually not recognized it
Then reboot
Now you can change orientation using any orientation app.

Battery Level Instant Drop
Recently, muy phone has had several instances of instant battery level drop; not as in quick drain, but rather, immediate drop. I've been able to document these two occurrences :

Between the first and second occurrence, I uninstalled apps that were using data on the background (such as games and whatnot), I monitored the battery usage per application, disabled unused applications, and used motorola's app battery optimization. And while doing all that did in fact improved my overall battery life, that didn't prevent it from "spontaneously" dropping to near 0%.
Also, I  noticed  that in both cases, there was a slight increment in battery level, before dying (It was charging but I had to unplug it to attend a call).
Finally, there was no significant phone or battery heating that I could perceive.
Another sympton, although I'm unsure this is related in any way, is that my phone turned off, as if battery completely depleted, while having battery level at 15:

I've tried wiping my cache partition, and hasn't occurred since; however, I think that this might be purely coincidental.
My phone information:

I have not been able to find this question repeated here on SE.
Any further needed information I can provide, please ask.
Regards.

Are you sure your case is unique from ALL these former similar questions? How do those suggestions fail you, if you have attempted the suggested solutions? Even if you eliminate due to low confifence in the non-accepted, there are plenty of accepted answers to assume successful resolution(s) there to choose from.

Because many of the questions you suggest speak of battery draining, either by processes hogging resources or other similar situations. While I have had those issues, if you map the battery behavior, you can see a steep curve to low battery levels. Here, you can it's almost instantaneous, from literally a couple seconds. I doubt it's an issue of battery usage per application.

I think you are trying to find a presumptive solution that fits your mindset. How have you eliminated the possibility of a common solution?

Between the first and second occurrence, I uninstalled apps that were using data on the background (such as games and whatnot), I monitored the battery usage per application, disabled unused applications, and used motorola's app battery optimization. And while doing all that did in fact improved my overall battery life, that didn't prevent it from "spontaneously" dropping to near 0%. Also, notice that in both cases, there was a slight increment in battery level, before dying (It was charging but I had to unplug it to attend a call). Finally, there was no significant phone or battery heating

These are all significant factors that could have been (and probably still should be) edited into the post, rather than as expository comments. Thanks for the additional info, though, since it clears the easier solutions from the possibles.

Noted and edited :)

Better get the bad battery replaced.

System notification service error
Getting this error from system notification service. With two options, Keep it anyway (unsafe) or disable. I'm getting this notification in every 2 minutes. No matter if I select disable, or keep it anyway (unsafe).
I have restored my phone to its original factory settings two times, still the same issue.

Please modify your question with  your device name and android version.

That's the warning from Google Play Protect, which is quite new. It's detecting that app to be harmful, but often it detects some system apps as harmful (which are not available in play store). So if that app is a system app, then nothing to worry about. But if you don't wanna seen the warnings then go over to play store and disable both options in play protect. You can find that option in the left navigation bar....

Internal Storage Increase / Replace
I am not convinced that My Spotify is using an entire 1GB on my new Android.
I am new to Mobile Phones, but they seem to follow the basic laws and rules of Computer Science and Telecommunication. I can not understand how 200 songs downloaded in standard quality on Spotify can use a full 1024 Mb on the phone when on my laptop the same number of songs use only 343.8 Mb.
 I have cleared App data Caches, uninstalled Apps I am not using and my internal storage on my phone is still 7.50Gb out of 8 Gb.
I understand the internal storage package is most likely on a BGA so removing it is not an option.
 However is it possible to put a 128GB SD in an Alcatel U5 Android Phone, and then partition the 8 Gb of Internal Storage as a system reserved, for the Android OS? Then Partition the SD as ext2 and default it to App user data.
My concern with doing this is, one I have never taken a phone apart so I do not know how the hardware is arranged, two I bought this phone 3 days ago, it still has a warranty and I don't want to void the warranty and three I do not want to have to install extra Apps to do this as I am still learning the Android OS.
I would like to know how to do this with a windows laptop, as I can get an SD Reader, and also where the SD card is inserted into the phone when ready.
Any instructions on the general procedure or specific procedure for doing this would be greatly appreciated.
Thank you.

Any chance this is a consequence of different cluster sizes between the file system on your laptop and your phone?

Where do you see that 1GB of Spotify being reported?

How do i stop apps i dont want or use from redownloading?
Apps like Google Books and Flipaclip I dont use them so I Uninstal them but the moment I turn my Samsung Galaxy back on they redownload taking up space for app I do want/use in the future so how can I stop this if it is even possible D: please help?! TT^TT

Are those system apps? Are you pressing "uninstall" or are you just clearing data?

If they are system apps, then you're probably not uninstalling them, you're just uninstalling the previous updates. And probably your automatic update is turned on in Play store , and hence why whenever you boot up your phone and it gets internet access, it starts to download the available updates (which includes the apps you don't use/want). So go over to play store and disable automatic updates, or you can find the app (that you don't want to receive updates for), and disable automatic update by unchecking the option in your top-right corner. But if you want to get rid of those apps completely then you'll have to root your phone (only if those are system apps), and remove them afterwards, or you can just disable those apps (which don't require rooting) in settings if there is an option....

Note 8 lock screen PIN differs from startup?
I'm trying to fix a Note 8 that seems to be in a weird state. The correct PIN should be 4 digits. The lock screen won't accept the PIN (the OK button stays greyed out until I hit 6 digits, at which time it reports that the pin is invalid). But it seems to be the correct pin, as it works to decrypt the phone on startup.
The phone user says the only unusual thing they did before the problem occurred was to reset their Secure Folder password. They said that they were able to get into Secure Folder after the reset. Their secure folder password does not work to unlock the lock screen. Later, after the screen turned off, they were unable to unlock the phone.
I'm totally mystified. Can the startup and lock screen pins be different? If they can, can the problem be corrected somehow, or does the phone need to be reset?

They can be different upto lollipop if your device is rooted and using apps to do that. In later versions is not possible AFAIK. Given the way Samsung implementation is different from stock, it's probably best to reset

Unable to delete a huge UPDATE.APP file on Huawei P8lite
My Huawei P8lite running on EMUI version 4.0 and Android 6.0 Marshmallow is low on disk space. I noticed there's a huge UPDATE.APP file, it's taking 2.55 GB.

I tried to delete it, but it shows an error:

Error while deleting the file "UPDATE.APP".

How to delete this file?

Where is that file? Can you post the absolute path?

You can use some good file explorer like ES File Explorer and then try to delete the file, if direct deletion doesn't work then try renaming the file, then delete it. If that doesn't work then plug your phone into your computer and delete it from there. If nothing works then you might need root access to delete it.

Making the white bar below the keyboard black
I just got a new OnePlus 5T. I like to use a dark theme whenever possible, including the Android keyboard. In many apps, the bottom bar is white. (I'm talking about the navigation bar which has the three buttons, back, minimize and show active apps.)
Here are a couple of examples:

Any idea how I could make it black?

Use substratum theme engine for this purpose. You can theme individual ui element with the help of this. You screenshot looks like you are using oreo build so you can use substratum even without root. Check out this link

Problem sending Emails using android phone
I am new to this forum. I have come to this forum through google search and find interesting which leads me to signing up to this forum.
My boss is facing problem sending messages using business-email-account from their android phone. It's a very rare case where the client successfully received mails but most of times when my boss check "Sent Mail" after sending mail it shows nothing. when he send mail, in Outbox it shows "Failed". Please see below screenshot, where my boss is trying to send mail to me.
*** Actual SCENARIO:
When my boss send mails at home using their jio sim (mobile data), mails are not send but when he send mails using the office wifi mails are send everytime (No chance of message failed). However, mails are received successfully regardless of using any kind of network connection.
So please any help me out of this strange problem. Please ask for more info if required...

What email app is that? What kind of email server are you using? Could it just be that the SMTP server is not accessible from outside the office network? Please [edit] your question to add all the required details.

@Ems ask your boss to try to use a different mailing app, and not the one that is supplied with the phone. Let us know if he faces the same problem in the other app also.

Google Play store asks to uninstall apps on sd card to free up space for new installations
My phone internal storage has very less free space (about 450 MB), which is why I cannot install any new app, or update existing apps.
When I go to play store and click on any app to update, it asks me to uninstall apps to free space. However, the list also has apps that are completely on the sd card. When I click on the check box adjacent to an app that is on sd card, play store says that the required space has been freed.
But how is this possible? Apps on sd card should not take any space on internal storage other than cache. On the other hand, updates are always installed on internal storage. So, how can an app on SD card free up space on internal storage?
For example, consider the following app which is on SD card:

I want to update an app, which requires 46MB storage space:

When I tick the check box adjacent to it, play store says that space has been created for update to get installed:

How is this possible?

Apps take up space in internal memory also. Not just for cache

Can you elaborate a bit? Or provide link to a web page perhaps? Why should apps on sd card take up space on internal memory? Then what is my utility in moving them?

See App Install Location for what could be the reason

When your application is installed on the external storage:
The .apk file is saved on the external storage, but all private user data, databases, optimized .dex files, and extracted native code are saved on the internal device memory.

Using an Android phone as a wifi headset for Windows
Here is the issue:

I am working from home and want to use my wired headset on both my work computer and personal computer (not at the same time) without having to plug/unplug it every time
I prefer wifi over Bluetooth because of superior range and bandwidth
I have an old Galaxy Note4 and would like to plug my headset into it and be able to switch from one PC to the other

I have found solutions allowing to use the phone as a webcam or mic which would cover half of my needs (DroidCam...) and apps that send audio from the Windows PC to the phone (SoundIt...) but no app allowing to do both at the same time from a single app.
I could potentially use Windows "Listen" functionalities to create bridges between a VOIP client and the main sound card on the PC but this is a bit tedious and I am concerned this might add unnecessary latency.
Ideally, my dream app would:
- Create sound devices for playback and recording on the PC

Have a server app on the PC forwarding audio between the client on the phone and the local audio devices (allowing me to dial from the PC using Skype or other solution and get sound to/from my phone)
Have a client app on Android that would send mic and receive speaker audio of the phone to/from the selected server.

While it seems like a rather easy thing to implement, I cannot find any satisfactory solution. Any suggestion?

Phone Stolen and want to know if it was erased or a google error
My phone was stolen a week ago. I went home to log into my Google account in order to erase my device through Android "Find My Device". There was a check sign next to the erase, but it is still showing up on my account. I watched videos that told the owner that the phone was factory reset and I think my phone has not. Does this mean the thief has access to everything?

Were you able to see the location of the device when you tried to erase? After erase, does the screen still look like this?

"still showing up on my account" what do you mean by that?

My results said now that it can not contact the device and the last location that appeared was the area where I got robbed from. It says my phone has not been online since then. I tried erasing and it had a check ,but it did not email me or say the device went into a factory reset.

The "still showing up on my account" part was about find my device because some people say after the device has been wiped successfully the device will no longer show up in the android device manager window when you log in using your google account.

When you press on the erase option on the find my device, page, it tells you "If your device is offline, erasing will being when it next comes online" This is because Google cannot erase your device if it cannot connect to it.
The check mark you see, tells you that you put it into "erase mode" but it will only take place when it's online.
Had the device been online when you tried to erase it, it would have told you that it's online, and you would have seen the actual location.
I must conclude that the thief turned the phone off as soon as he got it. He could then put it through factory reset, or access your data while in airplane mode.
If you had a lock on your phone, the chances of him getting passed it, are very small. But If you did not have any lock on it, then he could have access to your data, and there's not much you can do about that.

Availability of security patches for Meltdown and Spectre on Pixel
The security vulnerabilities Meltdown and Spectre are referenced as CVE-2017-5753, CVE-2017-5715 and CVE-2017-5754. Those three variants can be gathered under the more general case CVE-2017-13218 (source).
It is said in the Android security bulletin from January, 2018 that the security patch level 2018-01-05 contains the fix for CVE-2017-13218. According to it, this has been dealt with in the Kernel components, which are binaries. For those, the bulletin says: "The update for that issue is generally contained in the latest binary drivers for Nexus devices available from the Google Developer site". The Kernel is distributed as a binary, and consequently it is not possible to check if the security patch is actually contained in it. On the Google Developer site, the last release available for Pixel Android 7.1.1 (because that's what interests me here) is NOF27D. However this release is already dated from April, 2017. Moreover, the code name of the release (NOF27D) had already been set way before that in platform/build (February, that would be the release 35 of Android 7.1.1).
Hence my question: is the security patch level for Meltdown and Spectre included into the last release of Pixel Android 7.1.1 available currently (NOF27D)?
If yes, does that mean Google has had a patch ready for those issues more than a year ago? If no, where can I find the security patch?

As end users, those two vulnerabilities is really something to be safely ignored.

@iBug Why would you ignore a vulnerability that lets any ad read your account login credentials or credit card numbers out of memory?

@DanHulme You certainly underestimated the difficulty to practice this vulnerability.

Excessive Battery drain on Note 8
I have been experiencing excessive battery drains in idle on my Note 8. About a month ago, I used to lose about 4-5% overnight (8 hours), but now I lose about 20-25%.
I performed a fresh factory reset and after 9 hours in idle, the battery results are as shown. Note that no third party applications, besides naptime, was installed. I used naptime to keep track of whether the phone dozes. My phone is running the latest update N950U1UEU3BRA5. Can someone please share ideas as to why the phone is being so inefficient? This kind of battery loss is not tolerable.

Battery drain is due to my wifi. Please see my new post here; any help is greatly appreciated.

How to deactivate backup apps on other phone remotely?
I dont have the phone. Its my old phone but I am still logged onto my mail. How can I deactivate it from my actual phone? I dont have the old phone on me.

What kind of phone was it? What kind of phone do you have now? When you say that you don't have access to your old phone, is this a permanent situation - you traded it in or sold it - or you just don't have it with you at the moment? What version of the OS is running on your old/new phones?

What backup? Google drive, or Samsung or what?

Assuming that you want to stop your Google account from syncing to your phone.
To stop Google from syncing to your device, you should sign out of your account. To do that remotely, go to this page, sign into the same account as the one on your old phone, scroll down to the bottom of the page, press on the name of the device, and press remove. This will remove your account from your old phone and will stop any new info from coming in. You'll have to sign back in, in order to resume sync.
If you want to fully erase everything that's on the phone, go to Android.com/find log into your account, and press erase in the pop-up press erase again. As long as your phone is on and has internet connection, everything that's on it will be deleted.

Keep flashlight on while in camera
I'm looking to use an old phone (like a Nexus 5 or Honor 5X) as a nighttime security camera with the Manything app, but this doesn't seem practical as I just can't get the flashlight working.
I plan to use Macrodroid/Tasker to turn the flashlight on automatically at night (as Manything doesn't natively support it), but the problem is that the flashlight turns off when opening the Manything camera view and can not be turned on while using the camera.
Is there a way to keep the flashlight on while using the camera in Manything? Or is there an Android skin which allows the flashlight to be turned on while the rear flashcamera is active?

I just tried the app, and it worked with the flashlight that comes with the phone. But when i tried a different flashlight app, it didn't work. So i guess you have to find the right flashlight. I'm using a Galaxy s5

@Abochur Ooh, sounds promising, S5 it may be then! Could you take a pic (and send it via imgur) of the flashlight working while in the Manything app with the rear camera feed open?

i could. But i don't think it's going to help you much, because it's the flashlight that comes with my s5, i don't think you'll be able to download it anywhere. Do you still what me to post it?

@Abochur I mean I'm literally going to buy an S5 for this express purpose :). Could you help me make sure I get one that'll let me use the flash like you can?

@beeshyams It can be any Android version, I'm planning on buying a new (used) phone for this :). On my own Pixel 2 XL, I've got Oreo and couldn't get flashlight+Manything camera going. And thank you, let me know if you find anything!

Sorry it looks to more complicated than I thought , I will revert if  I can find a way

@beeshyams I can root if necessary, but I'd much rather not!

This seems like a device specific issue. Some phones will allow the flashlight to be on while the camera is on, others won't.
The phone I'm using, Galaxy S5 has no issue with the flashlight that comes preinstalled, being on while the camera is running.
So if you're anyway buying a phone for this, Galaxy s5 or any other phone that allows it, should be your choice. (In my humble opinion, instead of buying this phone, you're better off buying a security camera with night vision...)
In the screenshot below, I have the manything app in recording mode, and the flashlight on, and I'm facing a mirror.

Using galaxy S5 on AT&T Android 6.0 flashlight widget that comes with the phone.
Note: other flashlight apps didn't work while camera is on.
I wouldn't post this as an answer had there not been a comment from OP saying:

@Abochur I mean I'm literally going to buy an S5 for this express
  purpose :). Could you help me make sure I get one that'll let me use
  the flash like you can?

Thanks @Abochur! Just one question before I literally purchase an S5 thanks to you (while I appreciate the suggestion, a night vision camera doesn't quite work for us given a very awkward placement needed!)—is there a way I can automate the turning off/turning on of the camera by time? For instance, is MacroDroid able to turn on the flashlight with a macro while Manything is open? Or maybe I could rig an accessibility service to turn on the flashlight with the widget then enter the Manything app again?

It's really all about turning on a widget using tasker or MacroDroid. If you have any advice on how it's done with tasker, I'll try it

It would be awesome if you could try it for me, I'd appreciate it :). The app I'll use is TouchTask—with that installed you can create a new "Task" in Tasker, then search for "Actions" and tap the one with the TouchTask to get started. I'm more than happy to help you help me—I should have no problem setting up that to leave Manything, turn on the magical widget flashlight, and return to Manything, right?

@owlswipe It looks like it's going to take me some time to figure this one out. But as long as you have an automated way of enabling a widget, I don't think it should be a problem. I'd suggest when buying the phone, that you get one that has a 30 day return policy just in case....

That's a good call, and thanks much for the advice :). I'll try to pick one up and let you know how it goes!! Thank you!!

@owlswipe out of curiosity, did you end up purchasing the phone, and if yes, how did it go?

I'm so sorry to have forgotten!! I got a used S5 just as you suggested and it's working perfectly for my needs::). Thank you!!

Adding a new contact skips the phonebook, goes to viber
My grandma has a new Huawei phone that has an odd configuration. Whenever she adds a new contact, it doesn't appear in the phonebook, but in Viber instead.
Naturally when she goes to her phonebook looking for her friends and doesn't find them, even though she had added them earlier, she gets very frustrated.
Since she's pretty old, I can't expect her to figure it out on her own. Is there a way to fix this? Viber hijacking your phonebook and not letting you add any contacts is pretty annoying.

Go into her phone book settings, and make sure display all contacts is enabled

There are 2 things to keep in mind:

Is your grandma actually going into her phone's contacts to add people, or is she going into the Viber app to add people?
When creating contacts, my phone asks me WHERE to store the contacts. In my case, I have 2 options: one the SIM card, or on my Google account. She may have a 3rd option (Viber). She should select one of the other 2. (I recommend Google account).

There is also a setting on Viber to let Viber sync with your phone contacts (so tyhat Viber contacts appear in your phone, and your phone contacts appear in Viber). This should be under General

She's going into the phone's contacts. I tried to help her myself, and had the same result, hence why I came here looking for answers.

I checked extensively and there were no options to pick where the contacts were saved.

I checked the setting to let Viber sync with the phone contacts yesterday, and she let me know that all her Viber contacts appeared in her phone book today, but that seems hacky.

How do I find APN settings to use with a 3rd party SMS app?
I'm using an admittedly old (Android 4.0.4) Samsung Galaxy Centura (Tracfone) and I've run into a problem with regards to text messaging. The default "Messaging" app is quite limited and is missing the one thing that I wanted:(group messaging), so I switched to Textra for messaging. Textra is almost perfect, except that it won't send or receive an MMS!
I figured it was a simple matter of updating the APN settings, until Tracfone support informed me that this phone "does not have adustable APN settings," and could not help me any further.
I experimented and found that the stock Messaging app can send/receive MMS, so it's not a system-wide problem, just a Textra problem. I experimented with a couple of other SMS apps from the Play Store, and they all exhibit the same symptoms. SMS works fine, but MMS fails.
Textra does have a place to input custom APN settings, but I can't seem to find the proper settings anywhere. I googled "APN settings for tracfone" and tried a couple of the common results, but no go. I did find out that the phone is apparently running on the Verizon network, (the gateways ##########@vtext.com and ##########@mypixmessages both work) so I tried Verizon APN settings too, but to no avail.
Any ideas on what steps to take next? Surely it is possible, I'm just missing a piece of the puzzle somewhere. :|

Did you check in your phone settings under more networks>mobile network>access point names? Do you not have that setting?

The phone does not even have a menu option for APN or access point names.

So you have mobile networks but not access point names?

Yes, that's correct. The only menu option under "Mobile networks" is data enabled.

Can't think of a solution. Just strange that the stock one allows you to send mms but not a third party one, being that they both use the same process

Possible duplicate of APN setting is missing on Nexus 5 bought from US

Please try solutions mentioned in possible duplicate and edit your question if it doesn't solve

I don't think this is a duplicate. I did try the solution mentioned, but dialing that code just gives me a Verizon "this call could not be completed as dialed" answer. This is a US Tracfone being used in the US without a SIM card, so I don't really think its the same issue. As I mentioned in the original post, MMS does work with the stock messaging app, just not with Textra.

What Exactly is this *expletive* Rooting Business?
Sorry this is a rant. I'm using the file manager EX Explorer and i just want to create a folder, put some files in it, possibly rename the files. Why did i have to spend 4 hours going through youtube videos and forums talking about "rooting" and "rooting directory". It is the simplest process imaginable...just moving files into folder. I'm NOT touching any system files. Why do i need extra or to enable permissions? I don't understand. Just what exactly is this rooting business anyway? In the end i just followed the "hint" and selected each directory i needed for each file, a long laborious process. Why hasn't android addressed this seemingly silly and extremely frustrating issue?

This is not a place to rant. If you have a specific question, go ahead and ask. You don't need to root your phone in order to move folders. If you want to know how to move files, first search the site to see if your question was asked before. If it wasn't, go ahead and ask your specific question. -1

What files are you trying to move and from where to where? Specific folders are locked down by the OS to prevent tampering with system files.

Also, look at this thread: https://www.android.stackexchange.com/questions/236/what-does-to-root-a-phone-mean for more info on rooting a phone.

There's 2 parts to your question:

What is rooting: On Linux-based systems (like Android) the "admin" user, i.e. the user with complete access to the entire system is called the "root" user. Since this is a potentially dangerous thing, the "root" account is often disabled. "Rooting" your phone is a term used to describe the procedure that either re-enables this "root" account or gives you (the owner of the phone) "root" privileges.
Why do you need to root your phone: Well, long story short, it's your phone, you should have full access to it, shouldn't you? Most phones come bloated with apps that you do not need but cannot be uninstalled unless you have "root" privileges. If only for that, you should have "root" access so you can uninstall those nuisance apps and free-up some memory, storage and battery power.

No Google Play Store on Huawei devices, nor within Huawei HiApp store
I recently got a Huawei P10, but there is only Huawei HiApp store, not Google Play Store. I want to download the Google Play Store, but I cannot find it in the HiApp store.
How can I install Google Play Store on this Huawei device?

Huawei devices (and other smartphone brands) whose default ROM originates from China, have a certain geo-restriction that prevents accessing most Google apps and services and most (if not all) don't ship with Google Playstore pre-installed.
Instead the OEM based store called HiApp, is the default app store, with which you can download more apps. Fortunately the process of installing Google Play store is not a big hassle at all if you reside outside China (otherwise you might need to install a VPN beforehand).
Using the HiApp store app, you can simply search and install Google Play store in a few taps as shown in the screenshot:

You coud also you the web version of app store here: http://appstore.huawei.com
alternatively you get still get the .apk file on apkmirror and side-load it normally.
PS I have a Huawei tablet with China ROM, that did not have Google playstore preinstalled and I simply used the above process, and it works well  alongside microG.

The Google Play app should already be installed on your phone. Look in your App drawer.

Samsung gear app stuck on Update dialog and disconnect from my gear s3 frontier!
I have gear s3 frontier and I connect it to my galaxy s7 edge phone. It works great but for last 2 weeks when I open samsung gear app in my phone it show a dialog with this message:

Notice
A new version is available. Update the app to continue

I can't ignore it and the only option I have is to press the Update button. After that it show a screen that say :

Preparing to connect ...

When the progress bar complete, the app close automatically and disconnect the watch.
I checked "google play" and "Galaxy Apps" but there is no update available for "Samsung Gear" app. and currently I can't connect my watch to my phone.
The solution I tried to fix this problem:

I tried to uninstall Samsung Gear app and install it again with google play. It worked for few days but after that I have the above problem again

I use the option of "Connect to new phone" on my watch. It factory reset the watch and connected my watch to phone. But again after a few days I have the above problem.

How can I solve this problem. I seriously offended because both of my phone and watch was Samsung flagships but they can't connect to each other. If I can't solve this problem I will throw away my phone and watch and I will buy an iphone x with apple watch.

did you get a fix.mine is doing same thing. I can only get app to open if I have no data on phone (disable wifi and Data).

@RichK It just fixed after a few days. I have no idea what was the problem.

Get ADB TCP connection log
I was wondering if there was a way to get the ADB connection log (on-device), for when someone types:
adb connect <IP>

with their IP
EDIT:
Kind of like with your /var/log/auth.log on Linux, where when someone SSHs into your server, you can check the /var/log/auth.log and see their IP

first you need to connect the device to PC where you want to see logs via usb cable and allow the usb debugging fingerprints.
Than you can connect to the mobile via adb connect
port : 5555 (used mostly)

The OP isn't asking how to connect.  The question is about how to get logs of such events.

Decrypt SD Card Files Encrypted by Samsung Note 8
Few months ago I encrypted my Micro SD card on my Samsung Note 8 for security purposes, and 2 days back the phone overheated and asked me to turn off. After awhile I was trying to turn it on but got no luck. I brought the phone in the Samsung Service Centre and they fixed it by replacing the motherboard. And now the problem is, of course, I didn't get any chance to decrypt the SD card and now I cannot decrypt it because the phone kept telling to me that I have to use the same phone I used for encryption. I have tried a solution from this (https://security.stackexchange.com/questions/116750/how-to-decrypt-a-microsd-card-after-a-factory-reset-of-the-device-used-to-encryp) but no luck. Where I copied the encrypted files on my PC then format-encrypt-copyfiles... etc... Or maybe because the guys uses S5 here and I have Note 8. Whew! I really don't know what to do. I need some important documents in that SD card and even Samsung cannot give any solution about my problem. Hope you guys can give me some solutions. Apologies to all because I know that this issue has been asked here many times but I cannot comment in that so I've decided to make a new one. Thanks in advance.

Did Samsung copy your user data from the old mainboard to the new mainboard? If not the encryption keys are AFAIK lost and your data can not be decrypted.

They did not. Is it possible?

The purpose of cryptography like AES is to make it impossible to decrypt data without having the key. The key was in your user data therefore the encrypted data can no longer be decrypted. Breaking an encryption like AES (if AES and key derivation was implemented correctly) takes several thousand years. Therefore consider your data lost - start using backup and synchronization Apps in case you have important data on the sd-card.

Yes. Data got lost.. OMG.. This is life... What to do...

Will leaving a device on an NFC tag do any harm?
I want to leave my phone sat on an NFC tag all day long - will it do any harm to either the phone or the tag?
I'm worried about Android constantly trying to read the tag all day, and that this could cause unecessary battery use, the tag could get hot from constantly being read, etc etc.
Is there anything to back up these concerns, or is it fine to leave a device on an NFC tag for a long period of time? Will Android read the tag over and over again, or does it somehow know when it's placed on a new tag?
Note the device is a Samsung Galaxy S7 (Android 7.0) and the tag is one of the cheap 'NFC stickers' you can get from amazon etc.
Edit: not a dupe of the linked question because that only asks about battery drain. This question is about adverse affects in general (e.g. over heating the tag).

Nothing to the tag, and nothing to the phone except for power drain.

Creating a dedicated android device for my daughter, Custom Rom ideas?
New to this whole android game and needing some advice/help.
I want to set my old galaxy note 4 up for my younger daughter. I want to install a Custom Rom on it that will allow me to set up a handful of “default apps” (Talk, Text, Spotify, Kindle or Overdrive, clock, calculator, notes, and a couple of Games) but also remove the play store so no other apps can be downloaded and remove any browsers.
Is there a custom rom out there that can support this? Also... if play store is not on the phone how will updates work?
Thanks in advance!

This isn't a site to recommend different ROMs, because recommendation questions tend to be opinion-based, but if you're interested in how to lock down a device this way, and the answer might not be a custom ROM, then that's a problem we can help you with. Please [edit] your question if you're happy with other solutions.

@DanHulme wouldn't a custom rom be the only way to lock it down? Otherwise a factor reset would just remove anything that makes it locked down. (of course using googles newer security changes some things about a factory reset but still)

Thanks for the responses, sorry for being the dumb new guy haha.  The reason i asked about custom roms is because i did a bunch of research and that was the only solution i could find... however i don’t know how those work and what all the different kinds are, hence my question. I apologize if I’m off topic.

@LateralTerminal (and to OP too) You can always just root then move apps into / remove apps from /system - untouched by factory reset, and will save the hassle of figuring out custom ROMs.

@RyanF I still don't think it's totally off topic. But it will be until you update what Note 4 you have. Give us exact model number. You know the carrier, att, tmobile? Don't forget give us the android version!!! I can't give you a suggestion without that info. (Because I know custom roms for that phone)

This also may be possible with Parental Controls in Android

How to uninstall Button Savior (non root) from Samsung Galaxy Note 4
I asked this question here and somebody suggested to me that I should asked here.
A friend of mine installed an app called Button Savior (non root) from google play and then decided to uninstall it for whatever reason, but he was not able to uninstall it from his phone, he then asked me to help him to uninstall it from his phone. I searched in google for how to do it, and I found this link.
On this link it was suggested that I first should remove the app from the device administrators list (settings - security - device administrators) and then and uninstall it and if this fails then I should reboot the phone into safe mode and repeat the process. I tried both methods but when I try to remove the app from the device administrators list the setting crash and I got an error message "unfortunately setting has stopped working".
Any suggestions to resolve this issue ?

I would suggest trying to uninstall via adb. You'll need the following if you don't already:

ADB
Enable Developer options
After that, proceed as follows:

Find the package name of the application on your phone that you want to uninstall. The easiest way is to use Package Name Viewer, or in your Settings under Applications.
Enable Debugging mode through Settings -> System -> Developer options -> USB debugging
Connect your phone to your PC
Right click on an empty area in the Fastboot folder while holding the shift key, and click on “Open Command Window Here”.
Now in command window type the following command: adb uninstall packagename where packagename is the name you found earlier (usually looks like com.packagename.anotherthing)
As soon as you hit the Enter key, it will uninstall the App and show you Success in the command window.

There is an easier way. Go to Play Store and search for the app. When the app is found, you will have two options - open or uninstall..

When no sound comes out of wired headphones connected to "USB to headphone adapter", how do you get the sound to work?
background:

I have a new phone, Google Pixel 2, that does not have a 3.5 mm headphone jack
about 4 times out of 5 times when I try to use wired headphones --> the sound does not come out of the headphones but instead is emitted from the phone's speakers

things i've tried:

I have tried unplugging and plugging in the "USB-C to 3.5 mm headphone adapter" (or just "USB to headphone adapter" for short) and sometimes this gets the audio to come out of the headphones.
But many times no matter how many times (10+ times) I try unplugging/plugging the "USB to headphone adapter" into the phone... the audio does not come out of the headphones.

When no sound comes out of wired headphones connected to "USB to headphone adapter", how do you get the sound to work?

The only workaround I have found to work reliably is:

restart the phone right before you need to use the wired headphones with the "USB to headphone adapter"
after the restart, the sound always works on my wired headphones connected to the "USB to headphone adapter"

(
Side note:

The fact that I have to restart the phone and this causes the sound to always work... IMO indicates a software issue.
Some sort of Android service that detects the adapter being plugged in is not working properly and the restart ensures that the service is working properly.
Most likely if someone with better expert knowledge knew exactly what service needed to be restarted... restarting that service would be a better solution (probably faster to restart one service instead of the whole phone... and doesn't interrupt what you are doing on the phone like a restart).

)

I have an HTC U11. My headphones quite mysteriously stopped working. None of the tips online (audio output apps, restart, etc) helped. I finally chanced across the culprit: power-saving mode. The audio jack adapter toolkit needs background data access. Power saving mode restricts background data access. My solution: Go into settings, apps, select show system apps from menu, find the audio jack adapter toolkit, open data usage, and give the app unrestricted data access. Voila, sound over my headphones. Hope it works for others out there too.

FIXED!!!
I found the fix for this issue (atleast fixed it for my pixel 2 xl)
Goto Settings -> developer options -> Disable automatic routing to USB audio peripherals , and disable this option if it's enabled.
Try it out and let me know how it goes .

Proximity Sensor problem with my Samsung Galaxy J3 2016
I have a Samsung Galaxy J3 2016 with android 5.1 and whenever I receive calls, the screen keeps flipping on/off. I guess my proximity sensor is busted ?

Galaxy Note 4 Battery Drain, Have Been Able to Narrow Cause Down to SD Card. Suggestions?
I've had my Galaxy Note 4 AT&T model for a little over a month now.  I got it pre-owned, but even so it works great, almost as if brand new.  With the exception of the battery life.
I've noticed drain ever since I first powered the phone on.  Going through the initial setup and then just experimenting around with the interface for about 25-30 minutes led to 26% of battery lost.  The screen brightness was 25%, and there was not even a SIM card in the phone at the time, so it could not be attributed to any cell connectivity.  Also I can't blame any apps that were installed, as there were no apps installed by me yet.  In fact, after disabling about half of the built in bloatware I knew I would never use, I still didn't see any battery improvement.
Since then, just to give you an idea, it drains an average of 10% overnight, and this is with the app tray cleared, screen off, and airplane mode on (Wi-Fi off too).  Now, I know this phone is four years old and perhaps the processor and other components require more power than they used to, but that can't be normal.
I also did a video streaming battery test.  At almost no brightness and no other background apps running, I got almost exactly 2h30 of streaming YouTube videos in HD.  In contrast, a fellow YouTuber got 6h23 with the brightness at max.
I know this is not the battery.  The battery that came with the phone that I know is genuine Samsung, a brand new battery ordered directly from Samsung, and a third battery (that I'm not sure if it's genuine Samsung) all have the same drain problem.  Also note that none of the batteries do anything crazy, like "jump" percentages or die unexpectedly before the phone reaches 1%; the drainage is pretty consistent and always goes from 100% to 0%.  It's just that this happens too rapidly.
I've gone into the Battery section of Settings multiple times once the battery has gone below 20% from a 100% charge, and it always says that the screen is the thing taking the most power (around 10-12%), then the Android System following with about half of what the screen was using, then Cell Standby and Android System tied at around 2-3%.  Underneath that, any apps I was using are listed, at 1%.  In total, the whole listing doesn't even nearly add up to 100%; not sure if that's normal either.  I typically use the phone with 30% screen brightness unless outside, and the "Auto Adjust Screen Tone" setting is always on.
I've been able to narrow the problem down to the Micro SD card reader part.  I've had a 128 GB Sandisk Ultra in the phone since I got it.  But I've also used this same card in my previous phone (a Samsung Galaxy Luna), and there were no battery issues at all.  I also don't use it as an integral part of the phone's functionality (I don't store apps on it), it is only used to hold my music library and the photos/videos I take with the phone's camera.
I tried once to remove the SD card, put it in my PC and fully reformat it using the official SD reformat tool, then put it back in the phone (obviously I backed up the files).  This briefly fixed the battery drain, but after a few days it went right back to the way it was.
As another experiment, I removed the SD card and charged the phone to 100%, and didn't put the card back in.  Running the phone with no SD card so far has given the greatest success I've had with solving the issue; I got more than double the amount of time on a charge.
The only thing I can think of is that the Note 4, in its official spec sheet, only can accept up to a 64 GB card, and I'm using it with a 128 GB.  But other people on forums don't seem to be having battery issues.  I've also seen suggestions to update the firmware, but I do not use my phone under a major carrier's service, so updating is not an option.  It seems to be running the latest firmware anyway:  it's on 6.0.1.  Some have suggested to try the Greenify app; this seemed to help a little at first but that could have been placebo.  Ultimately I uninstalled it after a week.
I suppose I could just carry around extra batteries everywhere I go, or keep removing the SD card when I'm not listening to music or filming, but it's so small that I wouldn't want to risk losing or corrupting it.  I'm willing to live with this because the Note 4 is such a nice phone in every other regard, but does anyone have any other suggestions before I give up?  I would even consider rooting and installing a custom ROM, but I would like for this to be my absolute last resort if at all possible.  Let me know if you have any more questions; I'll be sure to give more information.

The only reason that I have not tried other SD cards with less capacity is that even if they fix the problem, they are as useless to me as not using an SD card in the first place.  I need the 128 GB of space to hold everything that I use.  The format that I mentioned in post was a complete low-level format, which corrected the issue for a few days, then went right back to the way it was.  Thank you for the response, though!

WhatsApp doesn't open on Android 2.3.6 - says "switch to a supported phone"
Whatsapp say app supported to 2020 but won't open from 2018-02-06

What's your question?

@DanHulme this question is asking the same thing just with more detail

According to whatsapp firm :
Supported devices
We support all Android phones that meet the following requirements:
Your Android phone is running Android 2.3.3 or later.
Your Android phone is able to receive SMS or calls during the verification process.
You will also need a data plan in order to receive messages when outside the range of a Wi-Fi network.
We only provide limited support to tablet users and we don't support Wi-Fi only devices at this time.

It seems from the OP that even though according to Whatsapp the app should work, nevertheless, it doesn't. And your answer is just proving that WhatsApp should work, it's not actually giving a solution

Mirroring an Android display via Android Studio
I have an Android (first-generation Pixel) with a broken display. While the display does still appear to receive touch events, its ability to actually display anything seems to be basically done for.
Before I get a replacement phone (which I will, in a few days), I was wondering whether I could mirror the display on a laptop via some of Android Studio's visual or command-line tools, or otherwise without installing third party apps.
Is this possible at all, considering how limited my interaction with the display is?

How about https://www.vysor.io app? Also if you're able to connect phone to debugging, you can do screenshots in Android Studio so that you can somehow navigate where you want.

TLDR; Yes because it receives touch events.
Why?  I have even done this with the original iPhone 2G back with a jailbreak.  Basically I would copy the configuration files from a working jailbroken iPhone onto the broken iPhone.   Back then I used Chickenvnc and a VNC root application.  The problem with Android is that I do not know of a current VNC application that let's you operate the entire device from VNC even with root.  There are literally zero to my knowledge.  My question here has gone unanswered for similar reasons.  Home Screen Launcher Completely Operated By Keyboard & Alpha VNC  But you have touch events so you should be able to configure the device on an identical pixel and then flash the exact same configuration onto the broken pixel.  The tricky part will be navigating the home screen.

How to change Android's Google Chrome's default downloader? (not under app - set default)
I set Android's Google Chrome's default downloader to ES File Explorer and now I want to reset it back to Google Chrome. I found this to be impossible on Android 7.0 - I tried to uninstall both Chrome and ES File Explorer and then cleared all default application in app settings yet when I download a file ES File Explorer comes up. The only solution is to remove ES File Explorer from the system. Is there another way to fix this without reinstalling the OS or do a factory reset?

Try resetting all defaults using this. If that doesn't help uninstalling ES is perhaps the way out short of factory reset

@beeshyams I've tried this and it doesn't help. I just did a factory reset to fix it.

I guess I was a bit too late....You have to just disable ES downloader from settings within the app itself. Next time you open a download link it prompts again for a suitabele app and then you select the preferred handler.

I do agree with you that its kind of a bug where you can't clear defaults in settings → apps , as I mentioned in this related post...only "workaround" is to clear defaults from within ES app itself.

You'll have to first disable ES Downloader (download manager) from ES explorer settings:

Open ES explorer and navigate to Settings → (Tools settings) → Download manager
Tap on Download manager and check Disable ES Downloader
Now open your preferred browser (Chrome) and open a downloadable link, it should now prompt you as before and select the suitable handler.
Essentially you would've cleared the default handler for downloading links.

Note: I have also observed a similar bug in Android 7, where the defaults are not simply cleared the conventional way (i.e by going to Settings → Applications → Clear defaults, for now this is the better way to do it whenever ES explorer is involved.
This may also depend on version of ES explorer in use. I tested with version 4.0.4.7
Hope this helps

Uninstall es explorer
Download anyfile with chrome (and then pop ups will let us choose what download manager will we choose, then select chrome always ask)
Reinstall your es explorer
Now your download manager back to original

Same app paid for twice due to some error on Google Play Store, no receipt of failed transaction, but money deducted
I purchased a game yesterday, however due to some issue the purchase failed, yet the amount was deducted. I contacted the bank and they registered my complaint and informed me that either I'll receive the money back or the merchant will. Being impatient I purchased the same game later, but my previous transaction was also sent to the merchant, which I found out when I enquired the status of my complaint with the bank. Now I have no idea how to resolve this, I have not received any receipt for the previous transaction as well.

As updated by OP the first payment has been cancelled after verifying in the payments Center
Since the payment had been honoured by the bank prior to the cancellation (likely), you can contact Google and talk to them and request for a refund (or from the Google Play Settings → Help and feedback)
Typical refund requests time line here

Follow the steps provided by Google support on how to request a refund.
Here's what you got to do:

Open play.google.com/store/account in a browser
Find the app in your purchased list,
Press on the three dots found to the right of the app name.
Press on, report a problem
In the drop down list, pick I purchased this but did not receive it
It will give you an option to describe the issue in full detail.
After filling in as many details, press submit

If however the app doesn't appear in the purchased list, use Google's page for reporting unrecognized charges, as they don't seem to havea double charge page.
Go to this page and fill out the necessary info.

Cant install a APK of an pre-installed app (Samsung galaxy a5)
I'm trying to download a APK for Spotify premium but because of my phone service (fido) Spotify came pre-installed. When I install the APK it trys to update the pre-installed spotify even though it's disabled. How do I install the APK?

Depending on your provider - I don't know much about Fido - you may not be able to uninstall it. Can I ask why you need to install the app if it's already on your phone?

The Spotify APK is modified

The best way is for you to uninstall the pre-installed Spotify first. You will likely need to "root" your phone. This site has some apps that you can use to root the Samsung A5.

WhatsApp Chat Backup crashed. Any restoration guides?
Yesterday night I had checked that my phone having a free space of less than 300 MB, but was totally fine. My WhatsApp Messenger is configured to back up everyday at 2:00 am (I am in the United Kingdom, GMT / UTC Time Zone +0:00 Hours). Today it so happened, when it tried to make a local backup of messages at 2 am (when I was asleep), it failed and looks like it even removed the current message store.
It informed that there was some error with the backup and if I would like to restore the chat history, and it can be done only once. I had to hopelessly say Yes, as the messages are really important and when I did, boom it restored the chats till February 8th, 2018 till 2:00 am GMT.
Current Situation: Whatever between February 8th, 2018 till 2:00 am GMT and February 9th, 2018 till 7:00 am GMT are missing and I am unable to find where the WhatsApp Database is stored.
My questions are:

Is it possible to get back my lost messages during the lost period of February 8th, 2018 till 2:00 am GMT to February 9th, 2018 till 7:00 am GMT?
Where does WhatsApp store its current msgstore.db.crypt12 file, as all I see in the Databases directory is backup?

My phone details:

Software: Android 6.0
Model: Lava X81
Free Space: 300 MB
WhatsApp

Version: 2.18.9
Backup Frequency: Everyday at 2:00 am GMT.
Online Backup: None

SD Card: None

Restoring that file is not possible as it looks like it is overwritten in the aborted backup / restore it is in the same directory you mentioned and created everyday). To my understanding, there is nothing you can do on your own to get back those chats, barring asking people to resend chats of that duration

@beeshyams Guess what, that's my status: "My WhatsApp backup crashed and I lost the messages for a day. So if you see this status, and if we had conversed yesterday, please I kindly request you to send me the chat history!" Not everyone's happy to do, but yeah, I really miss the statuses and pretty personal first time conversations we had! :(

@beeshyams Thanks man. I am planning to just leave it here and in any case, if there's a possibility of a solution, at least remote possibility, I would be really really happy to get the personal chats back. It's from a special someone and they just left out of the country, and not even possible to contact them. Is it worth asking WhatsApp, if by any chance, they have a copy in their server?

No. Won't help. WhatsApp stated policy is that they don't store messages on their server

I might have missed this info somewhere, but did you have  Google drive backing up your messages?

@Abochur No backups anywhere. I have mentioned it in the question. :( For some reason Google Backups didn't work for me.

Rooting Gionee P5W
When I tried Kingroot apk to root, it says that there is no root strategy available for my phone.
Is there any working method available for rooting my android phone?

Disclaimer I take no responsibility for this info whenever you root a device there is a chance that you will brick your device.

To root follow my answer at this post Backup/dump kernel image (and
full ROM) without root for Mediatek Devices
Now copy the boot.img file you got from this procedure and place it
in the Download folder on your device.
Download Magisk Manger from here [2018.10.22] Magisk v17.3 - Root & Universal Systemless Interface [Android 5.0+]
Install it on your device and run it.
Select Install and then select again install. Now select Patch Boot Image File.
The app will tell you where the file was created, flash this file to your device and you should be rooted.

Download the .zip file of latest version supersu to your computer
Connect your phone to the computer using a USB cable
Drag the SuperSU zip to device internal storage or SD card
Reboot your phone into TWRP recovery (Method to boot each device into TWRP recovery varies and Google for correct method for your device)
Make sure to back up the device in tWRP recovery]using Backup option
Click the Install button
Scroll down find SuperSU ZIP file you transferred
Tap the SuperSU zip
Swipe to confirm the flash
When the process is completed, tap the “Wipe cache/Dalvik” button that appears and swipe to confirm
Tap the “Reboot System” button to boot back into Android
Now the device is rooted and you will be asked to install SuperSU APK.Do not let TWRP install SuperSU APK itself do it yourself.

"Since your device is using Android lollipop": and why then did OP tag it "Marshmallow"? Just wondering; of course it might be the OP who's wrong; if so, maybe you [edit] your answer and point out what makes you think it must be LP – and maybe add if it works on MM too?

How to disable autostart of an app on LineageOS 14?
LineageOS used to have a function in the settings to activate and deactive the auto-start of apps inside Settings -> Apps if I recall correctly. I no longer find it in any setting option.
I'd like to avoid installing an extra app if there's a native function. The app in question is a RSS reader which I don't want to uninstall, but just not have running at every start.
I'm using LineageOS 14.1-20180203-NIGHTLY-titan.

Even since LineageOS was known as CyanogenMod, it offered a deeper way to manage apps' permissions than the one introduced by Google from Marshmallow onwards. This feature, known as Privacy Guard, can be accessed from within Settings -> Privacy.
To restrict it from starting on boot, hold on the target app in the list that's displayed, then find the Start at boot entry and flip its toggle. Even system apps can be restricted this way, provided you choose to display them via the menu located in the top right corner.
Note that this will prevent an app from firing up at boot, but that, if said app can receive push notifications and you use Google Services or microG, then it will be awakened to display the notification. microG offers a way to disable yet this mechanism.

Some time ago I replaced a phone to a new one using Android 7 (before it was 6) and my smart watch updated to Android Wear 2.0. Hard to tell what was the reason but since then each time a bluetooth connection between the devices is broken and going to be re-established there is a pairing request with a code which needs to be confirmed on both devices. Is there a way to make a phone and a watch to trust each other once and forever and to connect without re-asking a confirmation? This was the case with Android 6/Android Wear 1.1.
Not sure it matters, but the phone is
Asus ZenFone AR and the watch: Casio WSD-F10.

What phone and what watch is it? They should only need to pair once so it sounds like a software problem in one or other device. Please [edit] your question to say what, so perhaps someone with the same combination can find your question and help.

It is an issue across most Android wear devices, Wear 2.0 and any watch.
You'll see this issue all over the Internet.
I have two Moto 360's and both constantly have pair requests with my Android 7 Motorola Droid 2.
I have factory reset both, followed Google's directions and still does it.
Hopefully Wear OS 3.0 will fix it, but I've heard both of my watches are not getting that update, which is BS.

How to turn mobile hotspot off using ADB
I need to turn the mobile hotspot off using ADB. I'm using various Samsung phones with Android 7 & 8.
I'm planning on opening the settings activity and using keyevents. I know the Mobile Hotspot and Tethering settings page is com.android.setting/.TetherSettings but beneath that there is a Mobile Hotspot page. Does anyone know how to open that page with ADB?
I'm open to alternative methods of turning mobile hotspot on and off with ADB.
Suggested solution in How to turn on the wi-fi hotspot using ADB? does not work for the phones I've got.
On Android 7 and earlier you can achieve the desired result by turning on Wifi (which automatically disables the hotspot) and then turning Wifi off again. However Android 8 thwarts this by popping up a warning dialog which has to be dismissed.

Airpods w Android: on calls bluetooth constantly connects/disconnects
HTC 10, Android 7.0
Works great for music playback, but on calls it continuously connects/disconnects the bluetooth.
So using the airpods are useless for calling.
I have tried unpairing/repairing, and turning off/on the "phone" option on the bluetooth settings.
This issue is widely reported on the web, with android generally. For example here: https://forums.oneplus.net/threads/apple-airpods-connection-issue.497047/
This vlogger says to use just one ear of the airpods for calls when using android.  https://youtu.be/YUI4aZ1Uer8   My first pass testing indicates that using one ear is indeed a work around (though audio quality was poor, not sure if as a result of the single side)
How to diagnose/resolve?

Android 2.3.x Gingerbread can't access WhatsApp since 8th Feb 2018
I've got a Samsung device on Android 2.3.6. The message says the version on my phone became obsolete on Feb 24, 2020, but we are still in 2018. It is asking me to download the latest version.
When I try to do this, it says WhatsApp no longer supports my phone, I should switch to a supported phone.

Is your phone's date-time correct? It should have shown Feb 1, 2020 not Feb 24, 2020 as per this link: https://faq.whatsapp.com/en/android/26000006/

Hmm not to burst your bubble but I have a tablet running android 3 and hardly anything works.  Web browser throws certificate errors and lots of other issues. I would switch to another phone if you can.

From WhatsApp's FAQ page:

For the following platforms, you can no longer create new accounts, nor re-verify existing accounts. However, you'll be able to continue using WhatsApp:

Android versions 2.3.7 and older until February 1, 2020

Note: Because we will no longer actively develop for these platforms, some features may stop functioning at any time.

So if you're trying to reverify your account, above is the reason why it won't work.
I remember when WhatsApp stopped supporting some BlackBerrys, some were able to change the date of the phone to a few months earlier, and WhatsApp worked! So go ahead and try that. No guarantee that it's going to work.
If you are still having trouble, contact WhatsApp support for further assistance.
Update
A friend of mine had the same issue, he emailed WhatsApp, and they replied that it was an issue on their side and that it's fixed now.
If it's not fixed on your side, restart your phone and try again.

WhatsApp on Android 2.3.x is still supported, but the support will end next year. I should advise you to upgrade to a more recent phone, say Android 4.0.
However, using your phone native browser,  you can try downloading WhatsApp directly from the developers' site (the minimal requirement is Android OS 2.3.3) then enable Unknown sources. Install the APK and it should work.

It's also good to point out that uninstalling WhatsApp before following your steps, is not a good idea, as you can't reverify WhatsApp on those platforms

How can I change the Ethernet (IPv4) properties from my Android phone?
So my problem is: I am currently writing an Android application which has to get access on data sent via Ethernet connection. The app is going to replace a Windows tool which is able to receive data from another (automotive) device sent via Ethernet. When using this Windows tool, I have to change my computers Network Settings like shown below, so that the tool is able to set up a connection to the device:
Local Area Connection - Properties - TCP/IPv4 - Properties - change IP adress and subnet mask to the values which fit to the device
Now I want my application to receive the Ethernet signals. I am using a Google Pixel 2 with Android 8.0 and also have an USB-C to Ethernet adapter. I already tried to get an Ethernet connection by connecting to the Internet with an Ethernet cable plugged into my phone (with the adapter of course). So that means, receiving data via Ethernet should be theoretically possible. But I do not know, how I can change my phones Ethernet settings. The phones Ethernet controller also has to apply this certain IP address but there are no options in my phone's menu.
Do you guys know any way how I can change the phone's Ethernet settings/properties?

How can I keep my clock widget work in background?
I use clock widgets. The problem is that when I lock the phone, all applications are killed (except some system applications) including clock widgets. When I unlock my phone then I see that clock widget is stuck on time when I locked phone. I have to restart widget. Please tell me that how can I keep my clock widgets work in background without being killed when the phone is locked.

Why are all the apps getting killed in the first place?  Solve that problem first.

That shouldn't be the case. Apps shouldn't get killed when you're locking your phone.

My problem is solved. Following link helped me.

HTC U Ultra: Turn off automatic software updates completely
I do not want to update any apps automatically. I want this to happen at home when I am not charged for data volume. Are these settings correct for my wish? If not, which settings do I have to change also? I do not care about possible security issues that may arise. I can update from home manually once in a while.

Both. Good that you pointed out there are 2 update mechanisms. The Android version is 7.0.

To stop apps from updating over mobile data, go to your play store, open the menu on top right, -> settings -> auto update apps -> WiFi only

That used to be the case and the updates started nevertheless. I chose "Do not auto-update apps." now. Thank you for the hint.

On Oreo 8.0 and should be similar on Nougat
Apps: Play Store Settings → Do not auto-update apps or Auto update over WiFi.
There is a third option Auto update at any time - Data charges may apply. By selecting this and selecting Auto -update for an  app you ( from 3 dots menu) you can select apps that you wish to update over data  connection
These settings do not apply to system apps like Play Store, instant apps and they get updated even on data
OS updates: in Developer options disable automatic system updates and manually update, since these are typically big size files and accidentally downloading costs data
In your case HTC seems to have a different UI ;  disable the second option to prevent accidental download as explained. System updates aren't that frequent anyway

In your comment to the other answer, you mentioned that updation was happening for some apps. It shouldn't , unless  update is enabled as explained in third paragraph

Is it possible to install the Android browser and email app if they weren't built-in?
As far as I know, older Android tablets/smartphones have the Android web browser and email app as their built-in web browser and email app.
But my Android smartphone does not have those. My Android smartphone's built-in web browser and email app are Google Chrome and Gmail. I guess that is because the version of Android OS of my Android smartphone is a bit newer (Android 7.0).
Is it possible for my Android smartphone to install the Android web browser and email app?

As you probably know, Android is a Google owned company ( through some nearly illegal trickery with creating two company's, that's a different subject however ) since they create Chrome and Gmail they'll always be pushing their own content on Androids ( Gmail, YouTube, Chrome, Etc... ) . If you would like to install the older browser and email application, you'll need to know what Android version you had previously, the browser changes with each new Android version.  Try looking up AOSP Android browser for the version you have now. Go back through the release versions until it suits your needs

P.S     Older browsers will lower your level of security hypothetically, This is due to unforseen bugs and vulnerabilities that may have been fixed for newer versions. Keep that in mind with any downgrade of software.

@Zillinium So it looks like it's not possible to simply do the installation without downgrading. Thank you.

Stock Android browser and email app were discontinued since KitKat :

Google puts Android’s stock e-mail app in the Play Store
Android 4.4+ KitKat ships without browser app. OEMs have to license Chrome or build their own

They have been replaced by Gmail and Chrome as commented. Even if you are willing to face security risk to have it installed you can't downgrade from Nougat to KitKat (extremely unlikely). Only option left is to run a device of pre KiKat OS having those stock apps

if you are really interested in installing those previous applications; you may download their apk files from reliable resource and put them in your phone SD card or internal memory.
once done, go to security options in your Android Settings and check Unknown Sources checkbox.
Now open your file Manager application of android phone or download from Playstore. After that open file from FileManager, it will ask to install the Application; agree the terms and install one by one; both of your required applications.
Dear be very sure to download apk files from reliable resource, as there might be compatibility issues and more security risks. And i'll be not liable of any damage to your device and Data.
This is the most easiest solution. Thank You

Thank you. My purpose was to test web pages and email templates in those two apps. I'm a web developer, by the way. I would give it a try when I really have to do the testings on my smartphone.

AutoHotKey equivalent? (paste timestamp, open app, external keyboard, etc.)
Desktop PCs have AutoHotKey, AutoKey, IronKey, etc. .
But as far as known, nothing compareable for mobile phones.
I would like to be able to do things like:

Instantly pasting timestamp in preferred date format (i.e.20180210115759 or 10.02.2018 11h:59m:19s) using a keyboard shortcut from an external Bluetooth/USB-OTG powered keyboard.
Pasting tinestamp with on-screen keyboard (without any bulky workaround such as copying to the limited clipboard first).

Open/switch to application (e.g. text editor) using keyboaed shortcut.

Ability to launch selected app directly from external keyboard hotkey to take notes using a portable bluetooth keyboard while the phone is still inside the pocket. http://android.stackexchange.com/questions/190819/allow-running-specific-applications-without-unlocking?noredirect=1#comment246822_190819

3rdParty strobe (flashlight already works)

Which Android version?

@BeeShyams: 4.3, 4.4.2, 6.0 and 7.0. In what way does that matter? :)

@TechLord A lot of ways. If the means of doing stuff didn't change from version to version, there wouldn't be a need for versions don't you think?

You know the lockscreen itself changes drastically between Android versions and between different manufacturer UIs, right?

I forgot mentioning 5.0

@SarpSTA @ AndyYan Thanks for explaining. Is there a solution, that adapts to each version? (not necessarily but just a bonus)

Is there any way to recover data from 2nd SD partition?
From the beginning. I was using Link2SD in order to save up some internal memory, but today I noticed that all apps moved to to second partition (EXT2) magically disappeared. I don't want to repair Link2SD because I'm going to change phone very soon. I want to recover data from /data/sdext2, but i can't mount it. I want to recover this data because I change SDCard too. Link2SD saying something about invalid argument during creating mount script. Is there any way to access this data so far? Or I must say goodbye to them?
PS. First partition is safe and sound. It works great.

Looks like it's not damaged at all. The app itself went wrong somewherr.

To access second partition on SD card if it's not deleted, you may adopt multiple approaches listed below. For deleted partitons or deleted files, you may use tools like testdisk and extundelete which doesn't seem to be the case here.
LINUX / WINDOWS
As mentioned by @iBug, you can remove SD card from phone and insert in a PC with Linux OS like Ubuntu. You will be able to access both partitions there. File browsers like Nautilus and Dolphin by default show all formatted partitions in left panel on newly inserted media.
In order to directly mount a partition from Android device to Linux PC, you can expose it as a USB Mass Storage device. By default UMS is disabled on newer devices but can be enabled by a little hacking.
Windows by default only mounts first accessible partition on SD cards and other removable media. However, if you want to access second partition on Windows, it is possible. You need to make SD card a local hard disk drive using a hacked driver like Cfadisk usb driver. Follow this link for detailed guide.
ACCESS 2nd PARTITION FROM ANDROID
Some custom builds of TWRP auto-mount SD card second partition under something like /sd-ext etc. If not so, you can mount it yourself in Android recovery or ROM, as you seem to have already rooted device.

Reboot in TWRP recovery and use built-in terminal app there. Or if you want to do it from ROM, install terminal emulator app like Terminal Emulator if you don't have one already. Third option is to use adb, in ROM  or in recovery.
Find how kernel names block devices on your phone:
~# ls /dev/block/

You will find a number of devices there. On a typical Qualcomm device, mmcblk0 will be representing internal memory i.e. eMMC and mmcblk1 will be representing external SD card. Though there will be many other internal partitions and loop devices, we are concerned with three entries of external SD card:
mmcblk1    mmcblk1p1    mmcblk1p2

Here mmcblk1p2 is the second partition on SD card.
For confirmation:
~# fdisk /dev/block/mmcblk1p2

This will show details about SD card second partition including size.
Mount partition:
~# mkdir /sd_ext
~# mount -o ro /dev/block/mmcblk1p2 /sd_ext

First command will create a directory sd_ext under your root which you may access from any file explorer or command-line. ro option in second command will mount the partition read-only so that you may not harm any data accidentally. You may eliminate this.
If not successful, you may need to specify filesystem yourself what you used at the time of partitioning:
~# mount -t ext4 -o ro /dev/block/mmcblk1p2 /sd_ext

To know which filesystem a partition has:
~# blkid /dev/block/mmcblk1p2

There are many other tools that can be used for the purpose like parted, fsck and tune2fs etc. but these might not be necessarily available.
Mounted partition will be un-mounted automatically on reboot. You can do this manually:
~# umount /sd_ext

NOTE:

Be cautious not to touch second partition on internal memory which may belong to bootloader. Or you may brick your phone.
All commands used above need root access and binaries are included in TWRP. You may install busybox in ROM if any command not found.

Remove the card from your phone and plug it into a computer running a Linux system (like Ubuntu or Fedora). You'll easily be able to access data on that card.

I'll easily be able to access both partitions?

Yes, of course.

Default volume key control LineageOS
So I prefer how my iPhone works in that the volume keys adjust the media volume.
Samsung has an option for this called "Default volume key control."
Is there a way to do this on a rooted device?
Basically I don't like how there are 2 separate volumes that I have to deal with.  I just want one.  I put my phone on silent when I don't want it to ring so I'm not concerned about the ringtone volume.

There is an solution [here] (https://android.stackexchange.com/a/188233/131553)

Media volume only does exactly this but does require accessibility settings.  Supposedly it doesn't drain your battery but I'm not 100% sure.
There is other options here https://www.xda-developers.com/apps-to-master-your-volume-buttons/
I experimented with a couple apps but ultimately many of them don't for example if your screen is off.

Why a Samsung J3 wont call/text but data works
A friend and I own the Samsung J3 model phone.  Both phones shared this exact problem within a day or two.
The issue was the phone could not call or text.  Neither incoming nor outgoing attempts were successful.  The kicker was the internet still worked without WiFi.  Any outgoing call failed saying there wasn't service.
The problem was resolved by manually switching a setting in 'mobile networks'.  Taking it off the network and putting it back on after a few minutes.
I'm wondering why this would happen to both phones in short time, and why changing that setting solved it.  Maybe the phone had an update that causes a glitch in that area?
Any ideas are welcomed.
Edit: wanted to also add the LTE data was on and operating with no Wi-Fi being used.

were you on LTE?

Yes and the LTE speed was weirdly faster than normal.  That may or may not be connected but I did take notice

Maybe the problem was that your network was not switching to GSM or WCDMA from LTE when you tried making call. Though calls in LTE can be made over VoLTE which I guess is not provided by your carrier.

Thank you for responding but I think i could have worded differently.  Why would two J3 phones with different carriers do exact same thing days apart?  Maybe a glitched phone update or something?

Indeed. Generally all smartphones automatically switch to different network mode when call is made while LTE is on, unless you have forced to LTE only.

Why are notification action buttons laggy?
Let me explain my experience with the Android notification action buttons feature, where notifications from apps (often social media / communication apps) have buttons attached that can be used to like the message, retweet, reply, mark as read, etc.
Inconsistently, but frequently, when I press one of these action buttons, nothing happens for up to 10 seconds. If I don't wait for the notification to react to my pressing of the button, sometimes the button press never has ANY effect. And yet, sometimes the effect is instantaneous.
I have more success with some apps than with others. For instance, Android Messages is pretty responsive, Google Inbox is mediocre, and GroupMe is downright atrocious (I often have to wait more than 5 seconds after pressing "like" for the action to occur, and sending a reply with the action button almost never works).
Does anyone else have this experience? Is it just my phone? Or is it a matter of implementing this feature intelligently?
For context: I have a Nexus 5X running the latest Android 8.1.0.

Stream any audio to DLNA/UPNP speakers
Is there a generic ways how to stream any audio from my mobile or table to my WiFi DLNA/UPnP speakers? By any audio I mean any audio output from any application - YouTube, Audible, BeyondPod, any music player etc.
I figured out partial solution for BeyondPod, a podcast client, and BubbleUPnP, where BubbleUPnP streams to the speaker when it is set as "external" player for BeyondPod. It's a partial solution because it works only for applications with support for redirection to external player. YouTube or Audible has no option to use external player.
And it is not ideal solution either. For example playlists are tricky, both BubbleUPnP and BeyondPod have their own playlists and they don't play along well. BubbleUPnP is unfortunately not just just audio forwarder, it's full fledged media player and its own broad functionality in this scenario it gets in the way :(
Is there a proper audio forwarding (re-streaming, re-directing) solution, an app or a driver, which would take any audio output and forward it to my external speakers? My speakers support UPnP/DLNA, Airplay and Bluetooth.

The only app I know that streams the entire audio output of your phone is AirAudio. It is capable of streaming to UPnP/DLNA speakers but does also support AirPlay.
It does require root privileges, though.

Looks promising. I haven't so far rooted my device but when I do I'll give it a shot. Thinking about it, forwarding all audio probably would require root. So far I'm stuck with bluetooth solution.

How can I ensure that files such as photos/videos are stored in the SD card in Android Marshmallow?
I have a Lenovo Vibe K4 Note phone with Android 6.0 Marshmallow. I have formatted my SD card as internal storage. As a result, when I view the file system either through my phone or my PC, both the real internal storage and the SD card appear logically combined under Internal Storage.
I have many apps installed, such as Google apps, that do not allow me to move them to the SD card portion of the logical internal storage, and hence reside in the "real" internal storage only (but that is not my question).
The problem is that when I take pictures or videos, they are also stored in the "real" internal storage. Now, my internal storage gets very quickly filled up, while my SD card is near empty. Moreover, as logically both appear in the file manager as one "Internal Storage" category combined, I am not able to figure out how to move out the images from the real internal storage to the SD Card.
My questions are:

When SD Card is formatted as internal storage in Marshmallow, how can I enforce that certain files are stored in the SD Card? How can I ensure that new photos are stored in the SD Card?
How can I move existing files from the real internal storage to the SD Card?

@beeshyams Could you please elaborate, maybe as an answer? Thanks.

this is one option

Stream Audible audio to DLNA/UPNP speakers
I would like to listen to my Audible audio books on external speakers because the tablet's internal speakers are too weak and headphones are not always practical.
In another my post, Stream any audio to DLNA/UPNP speakers, I asked if there is a generic solution to stream audio output from any app on my Android devices, if there is no generic solution then have anyone figured out a specific solution for Audible?
Audible doesn't seem to support external players, so I cannot use BubbleUPnP like I can with BeyondPod for free podcasts.
I have nice external speakers, Panasonic SC-NE5DBEB-K by the way. When I am home, my tablet and speakers are on the same home wireless network, I would like to listen to Audible when doing household chores for example, but the tablets internal speakers are too weak, I have to move around the house, it sometimes noisy and headphones are not practical, I still need to hear other people too.

So I got official response from Audible team:
It's Bluetooth, Auxiliary Input (audio jack, ie wired speakers) or ..burn a CD!
UPnP/DLNA - not mentioned.
So it's Bluetooth I guess for me. Not the preferred option :(
For for completeness' sake, here is precise citation from Audible Customer Service team email:

Bluetooth
  If your mobile device and speaker support Bluetooth, your audiobook's will play through your speakers similar to how a phone call comes through via Bluetooth. The Audible app must be open and all functionality for the audiobook (changing chapters, narration speed, playing, pausing, etc.) can only be changed through the Audible app on your device.

If you download your Audible purchases to iTunes (which can decrypt Audible files) your desktop, then you can send the audio from your computer to the unpnp renderer. At least it works on a Mac.

scp for "Material Terminal"
OS: 5.0 Lolly-pop
Device: Samsung Galaxy note 3
Using the terminal emulator "Material Terminal" is it possible to add an ssh command scp?

I believe there is a way for rooted devices.

You will need a binary executable of the command you want.
Rename it (or don't) to what you want to type in the terminal to execute it. (no filename ending)
Copy the binary executable to /system/bin/sh (root-supported file explorers can do it)
Change the file permissions to r-xr-xr-- (ES FIle Explorer can, and perhaps other root-supported file explorers).
Reboot.

I haven't tested it but do believe it works.
