Outlook keeps asking for login credentials during setup
I'm trying to switch from a windows mobile to android. My main problem is moving contacts which are saved on windows mobile in an outlook account.
Therefore i tried to download and configure outlook on Android, but have no luck on entering the user credentials.
The following happens:

I enter the email (which does NOT end in '@outlook.com', i used a normal mail address to sign in at outlook which works with outlook on windows 10, windows mobile and web).
I enter the password.
After entering the password the outlook app authenticates on android and gives a message, that the server configuration is updated, and i need to re-enter password.
I reenter the password.
I'm asked if the application is allowed to access outlook and answer yes.
Password question step 2 appears. From this moment step 2-5 are endless loops.

What i've tried so far:

Delete the app cache
Delete the app, reinstall it from play store

Both did not work, same behaviour as before occurred.
I have tried to enter another outlook account ending with outlook.com - only one time password was needed and everything works - but as this is not the account with contacts it is not so useful.
So how can i enter my main outlook address to outlook? Or is there another way to get windows phone contacts to android?

See answers here for windows to Android contacts transfer

@beeshyams thanks found a workaround. Add a second outlook.com-alias online to the existing account and log in with this alias. then you can easily send the contacts from outlook to android.

Answer:
there seems to be a bug if you use outlook accounts which are not ending on outlook.com.
If you go to https:\login.live.com you can login with other credentials.
There is a menü "Your Informations" where you can edit the email or telefon alias.
In this menü you can create an outlook.com alias.
With this outlook.com alias login from Outlook on outlook mobile to Outlook.com works and contacts can be retrieved.

How do I stop the home button from waking the device?
I keep pressing the home button by accident in my pocket.
I have an S5, Cyanogen Marshmallow, rooted and xposed.
I can't find any way to stop wake on home with cm.  For Touchwiz there are xposed modules which stop this... How do I stop it on CM?

I can't confirm this for CM13, because I no longer have access any CM13 device, but on CM14 and on LineageOS there is a Home Button section in the settings for hardware buttons. It does have a Wake Device option that can be toggled on or off.

pocket lock which works on proximity / gravity sensor is well rated and may do the trick for you

@Duane Dibley thanks, I found it. I'm used to Touchwiz and it's a pleasant surprise when I don't have to struggle to customise my device! I also salute your good taste in telly :)

The setting was in Settings › Buttons – just toggle off Wake Device there. Duh!

"Phone may be monitored"
I'm seeing this message is because I installed a device owner, right?  (Note that I'm talking about a "device owner" in the sense of a special device administrator app, not the first user in a multi-user setup. Thanks to Izzy for drawing my attention to the possible ambiguity.)

This is Android 6.  I never saw this message on different device running Android 5 with the same device owner installed.
The device owner must be configured immediately after a factory reset, before setting up a user account.  I could factory reset the device and see if the message goes away, but I'm hoping to avoid that since I've already set up a bunch of other things.

This message is shown when a device owner is set.
I bit the bullet and reset my device.  It only cost me a few hours of setup.  The "Phone may be monitored" message appeared when I ran the ADB shell command dpm set-device-owner.

How do I get rid of spam SMSs that do not want to delete?
I get these spam SMSs on my Sony Xperia. I try to delete them, but I can't. I select the SMS to delete, then confirm to delete. It takes ages and then my phone tells me the message is deleted, but it is not. It is still there!

Go on setting and open application section . Now go to system apps and search message application . Open it and click clear data and also clear catch . By doing this your problem will be solved

That will probably unrecoverably delete all messages, yes. The OP may want to use a backup tool first!

I did go to Settings>>Apps>>ALL>>Messaging and clicked on Clear Data. It also cleared the Cache simultaneously. I went back to Messaging and found a screen saying GET STARTED. I clicked on it and all my messages were there. Tried to delete the unwanted ones, but I still get the same result. Went back to Settings to find data all the data was back again. Did I go to the wrong place in Settings? System apps are not separately listed on my phone.

Can I remove a virus by flashing my android?
Guys my android is rooted, it was working fine . One day when I turned on my android many notifican like "setting has stoped" began to come . I was redirected to homescreen again and again . To remove this virus I reset my android tablet but even after factory data reset my problem was not solved . When I connected to wifi then automatically new apps were downloaded and I also noticed that wifi and unknown resourses were automatically enabled . I decided to reset my android again but there was again no improvement and some kind of porn apps became system apps . I also did hard reset but that also not worked . Now I am thinking to flash my android through SP Flash tool . Will it work?

It should work. By the way how did you root it?

I did it by the help of king root

so, was it like this from the time you rooted or after?

which device has the problem(which phone do you use?)

All this behaviour can occur if the application you used to root your phone installs some kind of malware or you get a malware at a later point. You cannot remove this by a factory reset as it does not remove root or system apps and does not rewrite the system partition. Your only rescue here is to download SP Flash Tool and flash your system image, as flashing a system image rewrites your system partition and will remove every unwanted app, but you will lose root. If you want to root it again use SuperSU with TWRP. It will not install any malware and your problem will get resolved.

How to uninstall or replace Joy Launcher?
This morning my Android mobile started asking for permissions for a "Joy Launcher" app that I've never seen (or at least noticed before).  This appears to be an official app from the manufacturer.
https://play.google.com/store/apps/details?id=com.tct.launcher
I also found this article indicating that Google recently discontinued their Google Now Launcher, but I'm uncertain as to whether this has any bearing on my situation.
http://www.androidpolice.com/2017/02/03/google-will-discontinue-google-now-launcher-coming-weeks/
My biggest concern is that it's suddenly asking for unneeded permissions.  It seems unusual to me.  I haven't been able to disable it.  Can anyone shed some light on what's happening and/or any insight as to how I can remove or replace it?

I'd first start to check whether it's a pre-installed or user-installed app (in the latter case, and being sure you didn't install it, you might have a malware problem – in the former case, it might just have been a "regular update" with the new version requiring additional permissions). To do so, go to Settings › Apps and check whether "Joy Launcher" appears under "Installed". If it's there, it's user-installed. If not, check in "All", where pre-installed apps are listed as well. PS: That's also a place where you can uninstall or at least disable an app.

@Izzy I'm pretty sure that it's not preinstalled.  I use a startup manager to turn off unneeded applications at startup (e.g. Fedex, etc.).  Malware was initially my concern, but I'm reasonably certain that the app is from Alcatel, my mobile's manufacturer, since two other apps that I know came preinstalled on the phone show the same author in the Google Play store.  I must admit that my experience with launchers is very limited.  At this point I'm mainly interested in finding out if or how I can replace it.  I'm not a fan of unsubscribed, forced updates.

Jim, if it didn't come preinstalled, then who installed it if not you? If you suspect Alcatel: was there some "system update" from them that could have added it? If not: installing apps without user consent is malicious behavior in my eyes. And have you meanwhile checked in the place I suggested? To help you, we need those details.

@Izzy, unfortunately my mobile doesn't give me a breakdown of user-defined apps.  When I drill into the app settings, the Disable button is disabled (greyed out). Tapping the Force Stop button seems to have no effect. I agree that it definitely feels like malicious behavior.  There are a lot of recent comments from people with a similar experience in the Google Play store.  Just a few minutes ago it even blew away all my screens, as it's done to so many others. :(

"the Disable button is disabled (greyed out)." Just the fact that there is a "Disable" button tells us it's a pre-installed app. What's more, it seems to be protected (hence "greyed out") – which is a good idea if it's the only launcher installed as otherwise, if you'd disable it, you could no longer use your device. OK, that mystery solved: You could install another launcher (a selection is available in my list here, make that the default (tap the home button, select it, chose "always") and see if you then can disable JL.

If by "pre-installed" you mean that it was installed by the manufacturer, I tend to agree.  However, it definitely was not installed when I initially received the phone.  This app appeared only several days ago in what appears to have been a forced mass update from the manufacturer.  I will try installing another launcher and let you know how it goes.  Thanks.

Yes, sorry: the term "pre-installed" is a bit misleading. Technically, I should have better used the terms "system app". From what I've learned in our exchange, I agree it must have been installed by that update from the manufacturer/provider who obviously intended to make it the "default launcher" (and the only launcher "pre-installed", which is why you cannot disable it). I somehow doubt installing an alternative launcher will enable you to disable JL (without "special tricks" or "root powers"), but at least you will have an alternative to use.

PS: If you're satisfied by a replacement launcher, please see pm hide VS pm disable — the identity crisis for how to somehow get rid of JL (pointer: adb shell pm disable should do the trick, no root required). Same topic: How can I disable a stock app that has its Disable button greyed out? But again, don't try that unless you have an alternative launcher installed.

Thanks for all the help, Izzy.  In the end, I haven't been able to disable the app via Android's App settings, but after installing a different launcher, I was able to prevent Joy Launcher from being loaded at startup using the Startup Manager (https://play.google.com/store/apps/details?id=imoblife.startupmanager) app, so in effect it's at least using zero resouces now.

That's a good first step – and probably a good compromise. Have you tried pm disable? Then its icon would also be removed from the launcher and save you some space there. Btw: Have you considered to answer your own question with a short step-by-step guide? Might be helpful to others (there were already several "me too" posts we had to remove here).

Unfortunately, I didn't get around to trying pm disable.  Switching launchers was good enough for me.  I'll post my workaround below.

I ended up disabling Joy Launcher and installing another launcher of my choice.  Joy Launcher can be removed from the startup items using any startup manager.  I very recently switched to the All-In-One Toolbox app, since the Startup Manager app I mentioned above in the comments has gone flaky lately.

"Aggregate" or "Multicast" sound to multiple wireless devices
So, here's my scenario: I have a android-powered device (tablet) which where multiple wireless (bluetooth) speakers are registered. Now I want to stream music (using Spotify or Amazon Music) on ALL of these speakers at the same time.
Using a device running MacOSX there's a method called Aggregated Device which can supply this. I wasn't able to find something similar on android powered devices.

Is there a way to show Office 365 group calendars in the play calendar app?
I'm trying to get a calendar overview on my android device which has to include my google calendar (easy), my personal office 365 calendars (done) and the calendars of the exchange groups I am a member off (no chance).
Is there a way (or an app) that will provide a widget for the launcher that shows all the events from all the calendars?

Ok, for now the answer seems to be "No". I had a chat with the support from Microsoft and found some forum post on their sites. The Outlook App cannot show group calendar entries. To make those visible in your personal calendar (resp. create an entry) you have to accept the meeting invite which does not make any sense e.g. for a team holiday calendar.
The new Groups App from Microsoft in turn does not provide a comprehensive calendar view for all the groups you're a member off. Instead you have to check each group in turn. Also the app does not come with a widget.
Stands to say that there is a feature request to provide a groups calendar overview for about a year...

I cannot hear Google maps voice after update
After the last update, I cannot hear Google Maps voice while navigating. I only get a nerve breaking bell like sound every time I am close to a turn. I cannot see anything obvious in the settings on how to fix that.
Why did this happen and what can I do to change it back to voice navigation?
My OS is android 6.0 (LG G4 device)

Have you tried deleting data (you will lose off line maps) and cache of  maps? It may help

@beeshyams how can I do that?

Settings > Apps > click on maps > long press on Storage > clear data and cache

Found why this was happening. I suppose that after an update voice through bluetooth option was selected automatically. Since I didn't have (never had actually) any bluetooth device, no voice could be heard.
Fixed this by going to google maps settings and deselecting voice through bluetooth option.
hope this helps others with a similar problem.

I just had a similar problem - Google Maps suddenly no longer gave driving instructions via voice. In my case the problem was fixed by going to Settings (Android Settings, not Google Maps Settings) - Sounds and Vibrations - Volume. The volume for Media was set to zero, I have no idea how that happened. Anyway, after pushing it up to about 70% then all was well again.

I just fixed this by deleting Google Maps updates.  It's the updates that are the problem apparently.  Without the updates I get sound when I click on the microphone icon in the top banner, but with the updates installed all that happens when I do that is that a drop down window shows some distances and nothing turns the sound on.  So delete the updates and then set Google Play not to update the program.  Wish Google would fix this because the updates would probably be helpful if not for this bug.

First check with Aux or Bluetooth, if you are having same issues
Second, go to Settings - System – Language and input – Text-to-speech options. Then under the Preferred text-to-speech engine, check if certain language is selected; if not, select Language. Clear cache and check again.

What do you mean by 'check with Aux or Bluetooth, if you are having same issues'? I don't use blootooth.

This happened to be once on my asus zenfone and turned out to be problem device speaker (h/w issue). I found by playing music/sound on Bluetooth speakers and was not setting issue.. So, just in case.

The thing is that I can hear the bell sounds. Just no voice. That's why I think it is a settings problem after the update.

If you turn down the radio volume when the satnav is giving instructions you actually turn of the satnav volume.
Wait to you think the satnav is giving instructions and turn up the volume. The voice should then return.
Therefore, don’t reduce radio volume when satnav is talking.

Using TASKER to automatically change launcher/theme when launcher/theme is changed by other program
I am using a Huawei P9+ running on Android 7 (Nougat) and one of the annoying things with it is from time to time, the theme reverts back to the ugly Huawei Home theme, even though I use Nova Launcher by default.
Right now my strategy is I manually go to Apps -> Default App Settings -> Launcher to change it to Nova Launcher, however from time to time it would revert back again randomly.
I have Tasker installed and I am wondering if there is some way I can configure it so that whenever the launcher is changed to something other than Nova Launcher, it would be able to switch back to Nove Launcher automatically?
Forgot to mention I have Secure Settings (paid version) installed and my phone is rooted (using Super User, there is no proper SuperSu that works on this one yet).

How do i root on galaxy j5
I want root on my samsung galaxy j5 without pc. I can't root with 1 click root the one click root are all bad for this phone. I don't have twrp.Is any way to get root access with that phone? I don't have pc now.

I don't think there is a way to do that without a computer. You need a computer and Odin (Heimdall) to root your device

I don't think you can do without pc. You need to have a pc in order to root.

TWRP: compress files using file manager
I checked the TWRP 3.1.0.0 file manager and it didn't have the option to compress files; I've also checked AROMA File Manager and it lacked it too.
My question is, since twrp can work win zip files (flashing roms, ...) it seems logical to suppose that it can handle compressed files, then is there any possibility so that we can compress files or folders (possibly from internal storage) while in twrp recovery?

It's not available in the command line of TWRP, so I don't think it's possible

@beeshyams Actually, while TWRP's terminal lacks zip, it still has tar, gzip and xz, so support for compressing is present.

How to improve visibility of Android Nougat quick setting tiles?
Android Nougat introduces Quick Setting tiles that are available from pulling down the status bar on the top of the screen.
Unfortunately, on many devices, the tiles are light gray icons on a white background, which makes them very hard to see.
Furthermore, when they are enabled, the icons switch to cyan on white.  This makes differentiating between the on and off states challenging in good lighting, and nearly impossible in bright light.
For non-rooted devices, how can the quick setting tiles be changed to use a dark background, or at least, implement a higher contrast?

Lately I found a theme customizing app called substratum which is primarily for rooted devices, but works on some Nougat ROMs even without root. Have you tried it? If it worked for you, you can unveil wide plethora of themes and UIs for your phone.

@bikalpa Thank you.  I've been looking at some info on it thanks to your comment.  I see it definitely themes apps, but does it theme the quick setting tiles?

I think it does(I have not tried it though, I'm saying on the basis of screenshots seen on web). It kinda changes your system in the root level so don't forget to take a backup though.

@bikalpa That's why I haven't tried it yet.  How can you make a root backup without root?

Through custom recovery. You don't need to be rooted to install a custom recovery. All you need to do is unlock the bootloader.

@bikalpa Thank you!  Do you know if that voids warranty for most devices?

Unfortunately unlocking bootloader voids warranty in most of the devices. But if you own a Oneplus phone, they do support warranties even after unlocking the bootloader or rooting the phone.

How can I view iWork documents on my android device?
Is there a way to view (even better would be to edit) iWork documents on Android. I'm particularly interested in Pages, but there is also Numbers and Keynotes, all of them are part of Apple's iWork suite.
Also, in this page they say I should be able to do that from a web browser signing in to iCloud.com, but then a page is shown saying that my browser is not supported. I have Chrome 58.0.3029.83 running on KitKat 4.4.2

Doesn't it work if you open that site with your browser in desktop mode?

@beeshyams I was able to login, it shows a message saying "Your browser isn't fully supported", also can see the thumbnail of the document but it won't open.

Oh. It was a try. Well, Apple  says you can't, as you can see  here- so Android isn't supported , sorry. Nor is there any app per my search that can overcome this  , so the smart is that you can't

@beeshyams I see... they need to update the info on the link I found.

Booting problem due to internet
I had downloaded Android 6.0 Marshmallow's ISO from the net and tried to run it on VMware Workstation Player 12. It all went well. I was running it without installation so it asked me language which was default English. Sim Card was skipped. When WiFi connection was asked I skipped. It gave me a warning ... And I pressed skip anyway. Now the problem came. It gave me an error "Google Play Services unfortunately stopped" and redirected me back to language page and looped. I think it is because of internet connection which I am unable to configure.
Kindly suggest me how to solve this problem.
Thanks
Harsh

Link to the ISO you're talking about? Skipping the setup wizard on official Android-x86 6.0 r3 and CM13.0 r1 works alright for me when I was testing them not long ago.

@AndyYan Actually I think I downloaded it from XDA but I don't really remember.

Can u plz give me instructions on how to set up Wi-Fi or Internet whatever possible on VMware

I did not - I booted it natively from a USB stick. I did skip the WiFi part and it gave me no problem. Just try the official ones if you aren't using them - there's no reason to use an unofficial one unless you're after the latest, and even then Android-x86 officially offers an initial release of Android 7.1 for testing too.

@AndyYan I think you are right. I have downloaded Android x86 from sourcefourge latest marshmallow one. Hope it solves the problem. Thanks alot for your precious time

Default network settings on VMware is NAT  as i remember. Try to bridge network from VMware network settings. However i never had such problem for installed android on VMware. I had several times same issue on my android 6.0 device and i simply just cleared cache for applications and reset network. Try to remove completely Android from VM and reinstall. Also did you set other graphics and etc.. In settings. Or maybe ISO's fault and android security due network.

I am unable to configure internet

I don't know which version of VMware you've. But go to network control panel and change default from NAT to bridged and set connect at power on. Also go in network settings of android in VM and set same bridged. Reload VMware and try again to set up android.

12th Version...

Maybe your firewall blocks networking for VMware if that won't work uninstall VMware completely and if it asks to keep configuration files don't keep and install it again as administrator and firewall should ask to allow network sharing.

Buddy the problem is that I am weak at the field of network. So can you help me by giving step by step instructions. Windows 7 VMware Workstation Player 12

@harshbansal I recommend you to use Oracle VMware.

I'm not at home right now and i have to go but once i get home I'll tell you what might work. When you mounted android ISO did you set x32 or x64 and you might need to enable virtualization from bios settings.

How to download everything off broken Samsung when screen won't turn on?

Xperia S (LT26i) stolen. Can thief access internal storage?
Recently my xperia s is stolen.I am confused what are the chances that thief can access and take my all videos and picture out from my phone.
I had App lock in my phone with admin right so no one can access settings or uninstall apps not even force stop.
if someone reset phone then only device memory format or internal storage too?
I had 4.1.2 Android (Jelly Bean).
Formatting and installing new android OS(With pc companion or Flashing) into my phone.Is device memory or both internal and device memory erased?

The device storage is in fact the internal storage, just mounted differently, so if you erase the device storage, you will also erase the internal storage. If the bootloader of the phone is already unlocked, he could flash a custom recovery like twrp and access the files from there (over adb for example). But if the bootloader is locked, in order to unlock it, you need to erase all user data (internal storage), so the thief would not be able to access any data.

thief is not that smart who knows about bootloader.Btw my was rooted but not using custom rom,I installed Jelly bean by Sony official PC companion and I used kingo root to install superuser.Still any change?

Yes, it locks it to the first option, so yeah, the thief can access your data, if he has the knowledge to do so.

Difference between "unmonitored apps" and mDeviceIdleWhitelist
I've got a Galaxy S8 and have come across an interesting situation. Now, either something strange is going on, or I've got no clue how it actually works!
I've downloaded an FTP Server app on my phone which I wanted to leave running in the background. The problem was that, once the screen turned off, the wifi connection would drop after 5 mins and I couldn't connect to my phone.
I had enabled the setting for WiFi to always be connected and I know that the app has both PARTIAL_WAKE_LOCK and WifiLocks so I had expected the connection to remain in place.
I added the app to the list of "Unmonitored Apps" in the battery optimisation settings but this had no effect.
Using adb I could see that the UID of the service holding the WAKE_LOCK was not listed in mDeviceIdleWhitelist so I ran adb shell dumpsys deviceidle whitelist +PACKAGE_NAME and saw that the UID was now in the list.
After running this command, the app behaves as expected and I can continue to connect once the screen has been off for a while.
So my question is whether there is a difference between "Unmonitored Apps" and the mDeviceIdleWhitelist? If there isn't, is this a bug in the phone software?

Wifi hotspot from connnection
So, I have 2 samsung galaxy S4s. Dont ask why. One is running CM13 and the other Stock. Since you cannot put a phone into both master and slave mode at the same time, I would like to connect my stock s4 to wifi and use my cm13 s4 as a hotspot that uses that connection. Bluetooth tethering doesn't seem to work, so how would I go about using my stock phones slave-mode wifi to create a hotspot on my other phone?
Both devices are rooted, and the reason for wanting this is I would like to not haul my laptop with me on trips.

Have you tried fqrouter2 from playstore? It happens to have a Wi-Fi repeating functionality

@xavier_fakerat It doesn't appear to be compatable with jfltespr.

Do you have busybox installed? Try again with busybox, if that fails you can try NetShare-no-root-tethering. There is a Wi-Fi repeating functionality in that is included ( share internet connection with other android devices via WifiDirect) Please provide feedback if it works. Cheers

In that case you have to configure two interface in the device. Basically the wifi and the hotspot use the same resource, I did using my data mobile but using wifi you have to look how to configure an access point. With my PC using Windows you can do it but using your device please check if you have this Settings available:
Settings > Wifi Setting > Mobile AP

Does anyone know if it is possible to usb tether from android to android?

Detach app from market
Requesting updates on the fight of how to detach apps from Google Play

Titanium Backup is temporary...

.

Automatize a detachment with Tasker or anything else, is extremely verbose (and other things)

.

Resigning the APK does not work always (actually, worked very few times).

. Sometimes it breaks the app
. Sometimes it still shows on the store
. It can never be applied to system apps (like good old google keyboard)

Have you seen How to get rid of update notifications for a given app in Google Play Store? Does the TiBu approach described there (note the scheduler part) not work anymore? Nor any of the other approaches?

Thank you. Scheduling tasks help. Very close to the ideal. My only pain will be recreating all those schedules and filters every time I format the phone... since TiBu can't backup itself, forcing me to copy the data manually and keeping it somewhere

But I'm still looking for something better. By this method, it reattaches after a reboot. Plus, I have to create many schedules to cover all the times this thing resyncs

Even creating 5 schedules still don't cover the times. Apparently this resync is random. TiBu doesn't work

I'll double check but seems that the jrummy root tools app has that feature. Anyone else tried it and can verify either way feel free. If not ill have access on my rooted phone soon and will update my answer then..

AFAIK it's the same as with TiBu: if you detach an app from play, it gets re-attached within ~24h usually. The latter is a task performed regulary by one of the Google apps (not sure if Playstore itself does that or some other part of the suite).

Cannot paste files into System/Media
I am looking to change my boot audio but cannot change it due it not copying from my computer to my phone but I can copy from the device to my computer.
I have the latest version of Android Studio / SDK
I have the latest version of Droid Explorer
I can view my files and copy from but can't paste to my device.
Please can someone help

Hello my device is rooted and has supersu and exposed framework and BusyBox

Also I can make those changes if I copy to sd card and use es file explorer to paste them to system media folder.  Also before I installed busybox the folder contents of my device didn't display in Droid explorer it would connect but was a blank directory so that's been fixed but as for file permissions it hasn't as I have rooted it and given ADB root permissions etc but can only take files from the device in Droid explorer but can't paste them to the device

/system is read-only, so you cannot write there. I further assume your device is not rooted?

Agree with @Izzy for further guessing non-rooted. A rooted phone user is not asking such a trivial question here.

What do you need in that directory? Ringtones, alarms, etc. Can be placed in multiple locations and will work properly. What is the end result you are trying to accomplish?

@acejavelin Change boot audio without modifying /system?

You need to root the device and give permission to copy files using any root explorer.

No, you can't see.
No, blocking messages is different from blocking calls.
After your message is delivered you 'll see a single tick

For more options use Private space, Handcent SMS apps.

Actually I did a test, and it appears that I can actually see the messages which were sent to me while a contact was blocked, once I unblock it.

Reliable root procedure for LG G6?
Recently acquired an LG G6, model number: LS993
Android version 7.0
Is there a reliable procedure to root this phone?

When it comes to modern LG phones, waiting for an official bootloader unlock is often almost the only way out...

@AndyYan I was googling bootloader unlocks in general and actually this article which was written today came up by chance about the US LG G6 http://www.gsmarena.com/bootloader_unlocking_now_officially_supported_for_us_lg_g6_variant_as_well-news-25921.php

That's not it. Back then LG only unlock European variants; since G5 or V20 they added support for the US "open" variant because of complaints, but that's kinda pointless since the majority are still locked in with big carriers who have their own customized variants (and never eligible for unlock).

Nexus 7 won't boot after installing twrp
In How do I root my Nexus 7? step 7, I couldn't figure out what "on-device fastboot controls" meant. Now when I boot the nexus 7, the google logo with an open padlock appears for a second, and then the colorful 4-circles android animation spins, for many hours.
Just once, I saw the Teamwin splash screen, showing the version number 3.1.1-0 matching the twrp.img that I'd downloaded from dl.twrp.me and flashed in step 6.  (Yes, it's the right version, "flo" for nexus-7 2013 wifi.)
adb devices and adb reboot bootloader both report no devices found.
The battery is full, and staying full while the USB cable to the PC is plugged in.
How do I restore the tablet to a state where I can either give it commands from its screen, or from adb over USB from my win7 PC?
Is there some magical button-holding or adb command that can interrupt or prevent its infinite loop?  Holding the power button for 5 seconds returns it to the google logo, but then the dance starts all over again.  (It's fine to wipe the data on it. My eventual goal is to install cyanogenmod CM13.)

To shut off device adb shell reboot -p 2.  On device fast boot controls means using hard ware keys 3.I am not familiar with your device but suggest redoing the process

#3 was what I wanted to be able to do.  #1 failed because adb still couldn't find the Android device.  But #2 worked.  If you answer this with "hold power and volume down until you see the "fast boot" screen with the green robot on its back with the cover open", then I will accept it.  Thanks.

Partial answer
On-device fastboot controls means using the hardware buttons as explained in How to enter Google Nexus 7 Fastboot Mode.

Power off the device completely.To enter Fastboot mode, hold down Volume Down and Power.

Release the buttons only after the Fastboot screen appears, which shows the green robot on its back with its cover open.

Doing this made the Nexus 7 responsive again.  Then I could complete step 7 properly and start step 8.

Blackview BV6000 rooting problem / spyware removal / SP Flash Tool freeze
This is my first time here, so please be patient ;)
Recently I bought two smartphones, Blackview BV6000 for me and my lady. As I did some research I noticed that some Chinese brands have pre-installed spyware in Android build. Few days ago my girls' phone started to engage wifi, bluetooth, data transfer, precise location search and more on t's own. Quick scan with ADB through Command Line (CMD) on my Windows 10 x64 and I found these bastards:
1) com.adups.fota
2) com.adups.fota.sysoper
And I only scrached the surface. I wanted to root our phones so I could get rid of them, cause these apps are in .system directory and I have no access to them.
Here comes the hard part:
First I tried Kingroot. It failed. Then dr.phone, it failed too. Then I tried this solution:
https://dreamworks75.blogspot.co.uk/2017/06/blackview-bv6000-smartphone-mt67xx-twrp.html
But no luck either. Every time I try to flash TWRP, so I can root from SuperSU it won't start after plugging the USB cable. So, in summary:

Yes, I did read a lot stack exchange posts, YT tutorials and internet guides before I wrote my down here :D
Android version 7.0 Nugat, Windows 10 64-bit (PC), USB cable provided with Blackview set, SP Flash Tool 5.1624 and 5.1720
I am sticking to the steps in guide from link
Phone is turned off
Phone is not plugged to PC before clicking "Download" icon in SP Flash Tool
I accessed developer options on phone with enabled USB debbuging and OEM unlocking
I'm using ROM, recovery image and scatter file provided from needrom.com (this one exactly: https://www.needrom.com/download/blackview-bv6000-4/) and I tried few more from various sources
I have drivers installed on PC (checked with USBDeview), MT67xx included
I tried SP Flash Tool both with and without "authentication file" field
After clicking "Download" button in SP Flash and plugging phone via USB nothing happens

If you have any advice, hint or other means to get rid of this unwanted apps I would be grateful. I spent already two days trying to figure it out.

Did you try both methods for KingRoot? one with APK and one without APK?
https://www.androidweblog.com/root-blackview-bv6000s-oneclick-pc/

I ended up reading this question after I also tried basically all of the steps / websites mentioned in the question. But I eventually managed to install TWRP.

In order to make the SP_Flash_tool start flashing, after you plug in your phone that is turned off, press power button + volume up

If the flash tool errors, you might not have the right scatter file or twrp recovery.img

If you are not sure about scatter file, try flashing a stock rom (I simply clicked on the latest) and follow the PDF mentioned in the link and you'll be able to use the scatterfile from the downloaded rom.
After flashing the entire rom, it took quite a long time to boot (7 min ish) but the effect was as if nothing really changed. I had backed up my phone before flashing this stock ROM using the stock recovery so now is the time for factory reset, then restore data, then install all updates, re-enable again developer mode, usb debuging and oem unlocking and make sure that the updates actually got installed successfully and that there are no more updates.

Then try this TWRP (12.1 MB (12,783,616 bytes)) which also contains a scatterfile but that scatterfile didn't work for me, I had to use the one from the stock rom that I had just flashed. So in case the flashing still errors at this stage, I think you can tell that its because the version of TWRP is not right, not the scatter file.

Note: The file sizes are of the actual unzipped recovery.img

It is not unusual devices have data mining spy app in OTA updater. One can safely disable OTA updater from adb

settings - about phone - tap buildno 7x (seven) times

enable usb-debugging in developer options

open cmd.exe and cd into platform-tools directory

disable packages with pm
adb shell
pm disable --user 0 com.adups.fota
pm disable --user 0 com.adups.fota.sysoper

Repeat this after each factory reset. No root permissions required. One will lose the availbility to receive firmware updates, but it is still possible to update via recovery flashable zip

Is it possible to recover Google authenticator database
I am using 2 factor authentication through google authenticator and forgot to keep backup for one of the websites (cex.io). When I changed to new phone, I uninstalled Google authenticator from the old one. And now I am locked out of my account. I still have access to the phone and I have reinstalled google authenticator.
Now in this situation, is there any possible way to recover the keys for two factor that were saved on my phone? Customer support for cex.io is very slow and I am not sure when they are going to disable two factor so that I can setup for my new phone. If it is relevant, I was using Redmi 1s from Xiomi.

You should wait for the reply from the Support team of cex.io. As you didn’t save QR codes you cannot restore your tokens. Tip: save the QR code at the moment of token enrollment and keep it in a safe place. Then you’ll be able to restore your tokens on your new device. Or next time you’ll take a decision to change the phone, first of all, you should disable 2FA at your account settings (you will be asked to enter the OTP generated by Google Authenticator from your old phone). Then you should download Google Authenticator on your new device and add new tokens.

Google Authenticator uses "seed" values which are symmetric keys used to generate OTPs (One Time Passwords). This means there is more than one copy of these keys, one with Google and other with the registered applications. In a sense they are in pair, hence symmetric. When you try to register your new device with authenticator, there are more than two copies of these keys and this causes an authentication problem. If these keys were easy to be backed up and restored, the security might have been at risk. So, all you can do is re-register your new instance of Google Authenticator. For this you need to follow these steps-

Log in to your Google account (Since the Authenticator's key we have wouldn't be useful here, you can choose either Call or Message to get a code on your registered mobile number.)
After logging in, go to My Account > Sign-in & Security. In the password and sign-in method click on 2-step verification (you will be asked to enter your password again).
On the next screen, you will see an option for Authenticator app, click Change phone and select Android or iPhone(accordingly).
On your new phone install Google Authenticator app and open it, go to Set up an account and choose Scan barcode. Delete the previous entry if you have pre-installed the app and have an account registered.
On the next screen, enter the 6-digit key which you get on your app.
Let me know if there's an issue.

This is not for google account. I am using it for cex.io account. I understand how it works (well after loosing it), but I am not looking to get new keys for google. The seeds that were with me in my phone must be stored somewhere. And even after delete, there should be some way to recover it. I am looking for that way.

Smart Lock on Huawei P8 lite - only bluetooth option?
I've got Huawei P8 lite with Android 6.0. I'd like to use Smart Lock and Trusted Places to unlock my device, but in the settings I can see only bluetooth unlock option, nothing more. Why? Is possible to enable another unlock options?

It seems this feature has not been fully implemented in marshmallow builds (not sure of the reason). However there are some workarounds which can help achieve this (i.e. smart unlock based on localisation of wifi etc), you could either use Tasker and autools plugin or go for some third-party applications.

Is it possible to reset the compass calibration to factory settings?
My Samsung Galaxy S6 indicates constantly the wrong direction in Maps, compass apps, etc. as it shows the North always towards the left side of the phone. (This might be a long-term effect of the magnetic phone case.) Compass calibration is reported as "very good" and re-calibrating the compass by moving the phone in a 8-figure pattern doesn't have any effect.
Is it possible to somehow reset the compass calibration to factory settings?

Maybe you can find a configuration file and delete it.

Thankfully, it looks like removing the phone from the magnetic case and re-calibrating it fixed the issue.
I've thrown the magnetic case on the bottom of a closet and I'm never using it again.

I also had another problem, if I tried to pay with NFC it sometimes gave me errors.
I have removed the two magnets by making an incision with a cutter, in the back and front cover, so that I can still use the cover.

How can I remove a contact from the "favorites" page of the phone app?
The Phone app has a "favorite" page (the title is a star) which contains the contacts you most frequently/recently(or whatever...) called:

I find the contacts that appear there quite irrelevant and even dangerous (e.g. I recently blocked a contact and it still shows up there because said contact continuously called me)
My question is: how do I remove a contact from said page? The menu does not contain any option to remove them, moreover the contacts are not starred in the contact app.

Hold the contact in the favorites page, drag & drop it on 'Remove'.

@acejavelin Note: "the contacts are not starred in the contact app".

@GokulNC Oh gosh... that interaction is really unexpected & it also feels really weird. Thank you anyway, please post an answer.

Hold the contact in the favorites page.
Drag and drop it on Remove.

(This may vary for different phone apps. The method above works on AOSP stock phone app)

How to turn off screen overlay detection prom.. I have tried all ways which are on YouTube.. using Samsung galaxyj7

The real problem is this: nothing is working

Welcome to Android Enthusiasts! It doesn't help to post the very same image 3 times, and that large – I've fixed that for you. As for the problem: Have you tried our nice search? Your issue probably has already been dealt with and is answered multiple times, e.g.: “Screen overlay detected” dialog? (screenshots look familiar, right?) // Screen overlay detected, what is the problem? For more, follow the "search" link :)

Screen overlay settings needs to be disable for every single apps. Most of the time this occurs due to apps like Twilight and all. Check this
To complete the set up of the application permissions, disable the Draw over other apps feature for the enabled application by following these steps:
Open Settings>
Select Apps>
Tap the Gear icon>
Select Draw over other apps >
Select the application that is running in the background >
Turn Off Permit drawing over other apps >
Close and reopen the application >
Set the application permission >
Once the application permissions have been set, the Permit drawing over other apps may be re-enabled.
Note: Android OS 6.0.1 build AAF518 and later allows the option to temporarily turn off the screen overly for 2 minutes. To turn off the screen overlay for 2 minutes, complete the following;
Open Settings >
Select Apps >
Tap the Gear icon >
Select Draw over other apps >
Enable Temporarily turn off overlays >
Close and reopen the application >
Set the application permission >

S7 Edge - Boots into Odin Mode when trying to system update
I have a rooted Verizon S7 Edge on 7.0 and whenever I try to do a system update, it reboots into Odin mode and does nothing. FRP lock is off and OEM unlock is enabled.

Rooted phone firmware cannot be updated as one does with unrooted device. Usually, you would need to unrooted, flash stock recovery and update or flash stock with Odin and then update followed by rooting.
There is an alternate way mentioned in this XDA post GUIDE -Easy way to update a rooted phone without losing data using FlashFire, which lets you retain your custom recovery and update using Flash Fire. In this process, apart from reducing steps your data and settings are intact

I  have no idea if your carrier imposes additional restrictions

Messages app stuck notification bubble
I have had an odd problem where the Android Messages app had a notification bubble with a number of 1 or higher. That is, the app acts as if there is one unread message. Looks kinda like this:
But when I check inside the sms messages app, I see no unread messages, no unsent messages, no drafts. There shouldn't be a notification bubble. The app acts as if there's a hidden message always there.
How can I get rid of this number?

The OP originally wrote this in the question, so I'm posting it as an answer so the question stops showing up as "unanswered":

I dealt with this for a year or so, as it wasn't super significant, it just bugged me. I use an Xperia Z5, where Sony has their own messaging app clone, which I disabled soon after buying the phone. I used hangouts before finally switching to Android Messages, where I experienced this notification bug. To fix the problem, I simply enabled the built-in Xperia messaging app, and found a sneaky unread message: an undownloaded mms image sent to me a year ago. I deleted the message and the notification bubble went away. I went back to the Android Messages app and the notification bubble didn't come back.
For those who have a pure android experience and use the default messaging app, I suggest switching to another sms app. If upon choosing said app as your default sms app, said app shows you the same ghost notification bubble, then you have a ghost message that didn't show up in the Android Messages app for some reason or other. I hope this helps a brave googler somewhere.
tl;dr
Temporarily switch to another SMS app. You may have a ghost message that isn't showing up in the app you normally use. Delete the ghost message and switch back.

Click the 3 dots @ top right corner and MARK ALL MESSAGES AS READ.

It might be a good idea to include some screenshots to make it easier to see what you are referring to.

I went to settings--storage and clicked Apps. Then chose messenger and clicked clear data. That removed it.

Silence and vibration scheduler
I used to have Silet Time on Android 4.4 and it worked really well.
The application sets silent mode or vibration at scheduled time of the week.
I now have Android 6 and that application does not work anymore; I also tried Silent Hours and several others.
The Do not disturb mode works but it doesn't allow setting vibration, only full silent mode which is good for sleeping, but not in other occasions (office hours, meetings, etc).
Is there a way to achieve this on Android 6?

What happens if you  turn the volume all the way down to get to vibrate or tap the button up or down then touch the "Sound" icon then choose vibrate?

@beeshyams I doubt that is a duplicate. The linked question is about setting the mode manually via volume keys. Here, OP asks about setting it automatically ("at scheduled time of the week"). Might be a candidate for the [tag:automation] tag to make it clearer. The goal can probably reached via [tag:tasker] and the SecureSettings addon, but I'm not sure (didn't try for the specific mode requested here).

@Izzy will add the automation tag, isn't tasker a paid app? I would prefer a free one as I don't need the complexity of tasker only to put on vibrate at certain time.

Yes, Tasker is a paid app. A free 7-day trial is available, though (see our tasker tag-wiki). It's the app I'm using, hence I named it. For alternatives, be welcome to check with my list of automation apps.

Based on your comments, suggest using MacroDroid , since it is free (upto 5 macros) and easy to learn.

Your macro for scheduled priority  mode would look like this

Trigger (when to act ) is 5 days of week at the time and day required - here it is week days. Long press to add constraints, i.e,, schedule

Also, you may need to switch to this mode on demand. You can use this macro for that.
Create this macro and save. Go to widgets of your home screen and drag and drop Macrodroid widget on any screen. Assign this macro to that widget and use it on demand

Edit: Missed (sorry) adding that you would require a second macro in the on demand case where action would be Alarms Only or other options as you wish to get out of priority mode ,say as in the case of meeting at office

Advantages of using over Tasker -1. It's free 2. You don't need to secure settings ( which incidentally hasn't been updated in a long while ) 3. Easy to implement - hardly any learning

Did you get to try this ?

How do you access the graphs in Xlythe Calculator App?
I have recently downloaded the Xlythe Calculator App (link to Play Store here). The app claims to support graphing functions. But I have no clue on how to do so. Will anyone help?

I have  never used this application, but they say, if you want to graph an equation, simply type it in using the basic and advanced panel, then swipe to the graph panel to see it. ( Graphs functions (Y=X^2))

@xavier_fakerat Ahh, I looked around like you told, and I found out how to do it. Should I post what I found as an answer?

Sure please go ahead

So, I have been looking around the calculator, and I eventually found out how to graph the functions. I decided to answer my own question, so that it could be a reference for future users. Here's how:
Open the App, and swipe left. You should see this screen:

Screenshot (click image for larger variant)
Notice the X there (last line, previous to last symbol)? That's your variable for graphing. The graphs are rendered for Y=f(X), and you must type f(X)=[insert function here].
For example, let's say you want to graph Y=sin(X). Simply type sin(X).
The graph will be rendered as you type. It should be done as you finished:

Tap the graph to get a more interactive graph-based userface.

Keep in mind, this calculator cannot graph implicit functions. Furthermore the graphs aren't gridded. A more advanced calculator would be Desmos Graphing Calculator.
Happy calculating!

Hidden LED lights that are seen only by camera on my 3 Android devices
I accidentally found something hidden on the main screen of my Android devices: 1-4 blinking led lights that cannot be seen with the naked eye, but can be seen using the camera app. The location color and intensity of hidden lights vary phone to phone. Can anyone tell me what they are for? I found nothing in searches.

mention about three devices. Manufacturer, android version etc.

Proximity or ambient light sensor? I remember seeing those on a few rare devices, with naked eye also (faintly).

Those are proximity sensor and  light sensor they emit infrared light that's why you can't see them with naked eyes. They are located near the top area of the front side of the phone. More can be read here

"No command" in recovery mode after flashing with CF auto root
Using a Samsung 5 (Model J500FN).
I used Heimdall to flash the partitions (from CF-auto-root), which completes in download mode.
I then reboot the phone into recovery mode and just get a "Installing system updates" (or a message to that effect) and then a "No command error".
What am I doing wrong?

Woohoo! I had issues running Heimdall as root. But it works fine as a normal user.
I also had to enable OEM unlock in the developer options.

Help fixing odd AMOLED screen burn
I just picked up a used Samsung Galaxy S6 Edge+ and when viewing light-colored screens, it's very clear that the keyboard is burnt into the panel with a pinkish hue.
What's the best (free/fastest) course of action to reverse this AMOLED screen's burn-in permanently, short of opening the phone and replacing the display assembly? Is there an app to try, or might inverting colors for a while help?

It would need replacement - apps in some cases can fix minor burn in but not of this nature

You have to replace the phone screen, Amoled is famous for not being able to fully recover, in most cases, from burning

I logged into one of my freinds phone with my gmail and logged out this afternoon.
Still it is syncs all my contact list on gmail though I logged out of my gmail from her her phone. Please let me know how can I fix it. I want to delete the unwanted ids from her phone. It would be really time consuming job if I do this manually, delete one by one. Is there any better way for this?

Although you've signed out you most likely still need to unsync. What you can do is go to the apps where your information was synced in this case it's the contacts I'd assume, go to accounts and unsync from any gmail account then. In some Android systems this can be done through settings and not the contacts app.

How can I change my phone's resolution?
I would like to change the resolution of my s4 1080x1920 to 720x1280 not the dpi but the resolution. I have root access and am on android 6.0.1. How can I do this.
I want to do this to see how much battery I can save. Usually my phone last 3 days (normal use) on my custom 7800mah battery without charing but I don't really have much use for an UHD screen so I want to see if it can last longer by lowering the resolution.

Using adb, no root required
Use the command adb shell wm size 720x1280
Using phone, root required
Download any Terminal app, such as this one.
Type the command su to enter superuser mode, and then type wm size 720x1280 into the terminal.
Source: http://www.theandroidsoul.com/change-screen-resolution-adb-android/

Does this method survive a reboot?

Yes it does survive a reboot since I have tested it myself. I searched google play and found no apps that could do this. I will make an app myself using this method and upload it to the play store so others like me can have an easy way to change the resolution. Thanks @SSS

This really does help, usually I lose around 30%/day normal use but  I'm barely losing 20%/day nowadays. For anyone else doing this on s4, the best dpi for 720x1280 in my opinion is 300. I had 480 when resolution was 1080x1920

Since you don't want to use the dpi route, instead you can modify a system property in build.prop file.
Navigate to /system/build.prop and find this property name : persist.dash.max.rep.resolution under property value put 1280*720

How to get rid of "SMS is no longer supported" notification
My 5.1.1 tablet has an icon in the notification area. It looks like a Google Hangouts icon.  But the drop-down reads "SMS is no longer supported. To read and send SMS messages, please download Android Messenger".
Well, this tablet is wifi only, so I could never send SMS messages anyway (except faking it with Google Voice).  The annoying thing is, there is apparently no way to get rid of this notification icon.  I even tried installing Android Messages to see if that helped, but it didn't.
How can I get rid of this annoying and useless (to me) notification icon?

Have you tried turning off SMS option inside of Hangouts?

Thanks, while not strictly correct, your answer at least got me to open Hangouts.  There was a notification in the app to choose a different SMS app, and when I did, the problem notification disappeared. So thanks for the suggestion!

unintall / disbale hangout and instead install "Hangouts chats" https://play.google.com/store/apps/details?id=com.google.android.apps.dynamite

I don't see any SMS option inside Hangouts.

@suraj Google chat (or as you say "Hangouts chats") is only for G suite accounts.

This answer should not be accepted - there is no SMS option in hangouts. I also don't see any way of selecting a different SMS app (perhaps because I don't have one installed? But I have no need for one,  as my tablet doesn't have a mobile connection so can't send or receive SMS anyway, so I don't really want to install one).

Suddenly VOLTE not working on my moto g4 plus
I was using VOLTE services (from reliance jio in India) seamlessly since November 2016, but since June 2017 it suddenlt stopped working. I get an error "Unable to place call. Please try another method" while trying to make a call. I am able to access the internet and make/recieve calls from the Jio 4G Voice app.
UPDATES:

I have enabled "enhanced 4G LTE mode"
Did a factory reset
My jio connection is on and working. Also, I can place/receive calls from the Jio4GVioce app which means the service is working fine.

Have you recharged your JIO number? Have you switched on mobile data for JIO and turned on volte in sim settings?

@AshwinMothilal yes mobile data is on. What do you mean by turned on volte in sim settings?

Follow the below answer to turn on volte in your phone. Have you recharged your jio number? May be service is disconnected.

you can check answer here JIO VoLTE is not working with Moto G5 plus

Go to Settings/Wireless and networks/...More/Cellular networks and check whether Enhanced 4G LTE mode is enabled. Somebody (you) might have turned it off accidentally.

yes, its enabled

What's the result?

Same. It was enabled the whole time

I also had the same problem
Steps:

I tried to wipe partition, does not worked for VOLTE.
Removed the JIO SIM from slot 1 and inserted on slot 2.
then removed the JIO sim from slot 2 and inserted BSNL SIM in slot 1, BSNL works.
Then remove the BSNL SIM & insert JIO SIM in slot 1.

Now VOLTE is working.

Your best bet is to boot into safe mode and then toggle Volte on and check if it works there.
To (re)boot into safe mode: Press the Power key, then tap and hold on Power off, and then tap OK when Reboot to safe mode The Moto G4 will reboot and you should see Safe Mode in the bottom-left corner.

How to flash custom ROM together with modem and bootloader without odin or heimdal?
I want to flash the "newest" SimplRom (v5F) on a Galaxy Note 4 and the instructions say I need to also flash the modem and bootloader firmware at the same time.
Now I have three files: BL_N910FXXU1COI3.tar.md5, CP_modemCOI3.tar.md5 and SimpLite_v5.zip but I'm not sure how to flash them.
Most instructions tell me to use Odin, some describe the procedure using Heimdall. Odin is not an option for me (no Windows) and Heimdall seems to change it's user interface every now and then, so the instructions don't apply.
To make it short: is there a way to just use TWRP  or dd (this worked for TWRP) to flash the files? I've found a lot of instructions but since there are so many different file types, recovery roms, devices, tools etc. out none of the instructions seem to apply for me..
Do I need a PIT file for the dd approach?

There's something called Mobile Odin, though I'm not sure if it's up-to-date enough to handle newer devices.

Important note: Hey guys, thanks for the upvotes but this answer turned out  to not work at all.
The steps below don't break anything and this is why I thought I flashed modem/bootloader. You can use dd to make backups of the partitions below by swapping of/if but modem/bootloader won't be modified by the code I've posted..
In the end I had to fiddle with heimdall and boot the phone in download mode to actually flash the partitions.

Original answer:
In case anyone else wants to flash Bootloader/Modem and heimdall/fastboot/odin is not an option - this worked for me:
Extract/copy the files you need somewhere on your phone - e.g. with adb push ./bl_modem/ /mnt/extSdCard/, start a su-shell:
adb shell
> su
> cd /mnt/extSdCard/bl_modem/

then just flash the files with dd:

I double checked these names by first making a copy with dd and comparing sizes. The sizes won't be equal to the sizes of the files you're going to flash but they should be about similar size.

How to change the monotonous outgoing call ringtone
You know that annoying beeping you hear when you call someone, waiting them to pick up? I am completely sick of it and want to customise it on my Huawei Android phone. The question is: how do I do that? Thank you

I very much doubt that's possible at all. Those "beeps" that tell you whether the line is free or busy are not provided by your device, but rather by the carrier AFAIK.

It is called "ringback" or ringing tone and unless the far end has setup custom ringback tones with their carrier, you should get the standardized tone based on the country/region you are in, or more accurately the destination you are calling is in.
These "tones" and other sounds in telecommunications are standardized so they can be recognized by equipment that is intended to see (listen for) specific frequencies, combinations of frequencies, or tonal patterns to denote call progress or other events related to the call. They are often replaced in modern devices with digital signalling, but are still standardized for older equipment.
If you want to change YOUR ringback tone, then your carrier must support it and you will have to set it up with them. Otherwise the receiving caller's carrier is in control of what is heard during ringback in most cases. Your device has no control over what ringback is heard or delivered to callers.

removal of adware go.deliverymodo.com
I have Lenovo K4 note running on Android 5.1. This problem started today. Whenever I click on any page on chrome, the browser gets redirected to go.deliverymodo.com.
We have three smartphones and a laptop connected to the same wi-fi router, the problem is occurring  only on this one smartphone.
Have scanned the phone with Trend Micro, McAfee, Malewarebytes, and AVG antivrus Free Android security but none are able to identify / remove the adware.
Disabling JavaScript does prevent the redirection but then the regular links on the pages also do not work.
Can someone please suggest some tool that will resolve this problem.

Did you check if there's any malicious app installed in your device? Because there's no way Google Chrome for Android can be infected with adwares (like PCs). Did you try using different browsers?

Trying different browsers indeed is a good idea to narrow down the culprit. If they all show the same behavior, it's rather something intercepting your network traffic on that device (most likely the DNS, so all host names resolve to that site).

@Izzy Or a piece of malware that toyed with the hosts file.

@DeathMaskSalesman that would be toying with DNS while requiring root. Possible, yes. Also likely is some app that uses VPN functionality to reroute traffic. But that's all speculation without more facts :)

Have observed the same behaviour on UC Browser. Uninstalled and re-installed UC Browser but the problem persists. Checked DNS name on router -NETGEAR 2750U. It had been compromised but I set it back to the regular one. Two other devices  , Lenovo K3 and MOTO G4 plus, both having higher versions of Android , connected to the same router continue to work properly. I have not installed any new app, if something got installed by itself in the background then there could be a problem.

@Izzy I have done a factory reset but the problem still exists. I have deleted all the apps that I had downloaded, they were banking and e-commerce apps.

I have also tried using mobile data instead of wifi router but the results are the same.

Have also upgraded to android 6.0

Now things are getting weird: persisting after the factory-rest I could understand (some malware having managed to covert itself into a system app). But a system upgrade? What kind of upgrade was that: an OTA (just replacing some files), or a "clean flash" (wiping the entire system off before replacing it with a fresh install)? The latter should have killed even "system-app-malware", the former not necessarily.

@izzy I was running Android 5.1, and just went to settings->...system update and initiated update, it downloaded Marshmallow and upgraded to it, so effectively moved from lollipop to marshmallow. Planning to take it to service centre for clean install as I would not like to get into rooting myself.

That was an OTA then, and most likely didn't a "clean flash" – it just put itself on top of what was there. So if some malware converted itself into a system app, it was able to survive that. To really get rid of it, you'd need to do a full (clean) flash then. The K4 AFAIK is an MTK device, so you could use Flashtool (available cross-platform) and the matching ROM files to do so. I cannot tell you were to find the latter, though.

Looks like Onclick Functionality has been hijacked. Once I disable javascript, the problem doesn't surface. Unfortunately most of the sites that I access do not function properly with JavaScript disabled.

How to unlock bootloader, root and install TWRP on Redmi 3S+ (should work with Mi 3s Prime too)
On Redmi 3S+ , how do I :
I) Unlock bootloader
II) Install TWRP and root
There are confusing instructions available on internet. This is a self answered question detailing the procedure

Instructions to unlock bootloader of Redmi 3S phone are very confusing it took me many days to make it work, so I've documented the steps for anyone else trying. There's a lot of text but should be easily readable. Don't bother with part II, unless you have success with part I.

Part I - how I unlocked Bootloader on Redmi 3S+.
Intro: These are not a guaranteed "how to" steps. Because there's no consistent method that is available people have to go by trial and error, and none of the guides I tried worked. Everything about unlocking MI is inconsistent, even their own tool. And there's no meaningful feedback which makes it even harder to figure out what's going on. Just when I was beginning to think that all those reports of it working are fake, it worked for me. Seems when it works, people don't provide exactly what they did. So here what I did was recorded all the conditions under which I've successfully unlocked the boot loader. If you follow this exactly it will increase your chances of unlocking. But all the variables are unknown, so Redmi may change one and it might not work. So it's like superstition.
So, here are the conditions/states under which I've unlocked it:
Original version of MIUI: 8.1.6.0
Android version: 6.0.1
In Developer Options:

OEM unlocking: enabled
USB debugging: enabled

Settings / Mi Account / shows as signed in
Clicking on Mi Cloud there:

Every sync is off.
Find device is off
and Back up device is off.

Clicking on Devices shows:
- Redmi my phone number activated
Next, enable Developer Options by going to Settings / About phone (at the bottom) And tap a few times (10?) on  "MIUI Version" Till it will give you a message: "You're now a developer!"
Exit and go to Settings / Additional Settings / Developer Options -- and enable it.
There will also be "USB Debugging" - enable it
OEM unlocking - enable it to allow the bootloander to be unlocked
Next, you need to register and request bootloader unlock permission.
Register on miui official forum. I used my e-mail (you should have a secondary e-mail, not a good practice to use your primary one on sites like these): http://en.miui.com/forum.php
Once you've registered, you can request unlock here: http://en.miui.com/unlock/  (it'll come up in Chinese, click English below) and just follow instructions.
Next:
1) I had only ONE sim card in the phone's slot: #2 (slot #1 empty)
Same sim I used to sign in and request authorization with. I never got a confirmation message from Redmi. It's been a while since I've requested it, so I don't think it's because I've waited or "was patient" as some people say you have to be. I think it's rather the combination of things I've done. So just try right away or next day.
2) You need internet on your computer throughout the whole process. Without internet I only got first checkmark in the MI Unlock, which is "Verifying device", then on the "Unlocking" part I got a red x, and "error: unlocking redmi unknown error (-1)"
3) With my 3S phone tethering internet to the laptop, I logged into my MI account. Oh, by the way, sometimes it would give me "network error" during this login. I know I had internet, so it must be their server. I kept clicking without changing anything, and after a few times it signed in. Having said that, "network error" could mean anything and doesn't even have to be related to "network". (If you put a wrong information for example it might tell you that "account doesn't exist" for example, and after I unlocked it, now it just permanently gives me "network error" which makes me wonder if I lock it, will I be able to unlock again?)
Now it wants you to put the phone into Fastboot. Unplug the USB cable shut down the phone. Then hold Volume Down + Power and it enters Fastboot. Plug in the phone back.
4) Now, don't do anything. As I said you need to have internet throughout the steps. So use alternate internet connection (don't touch this sim). Just ask a friend to turn on hotspot on their phone for a couple of mins.
5) Check in a browser to confirm have internet. Now click unlock and hopefully it'll work for you as it did for me. Good luck!
MI Unlock (miflash_unlock.exe) version I used: 2.2.406.5

Part II - Install TWRP and Root
Disclaimer: this part could brick your phone.
1) Download TWRP. The official TWRP site's versions for "Redmi 3" didn't work for me. The one shared by a guy on redmi forum seems fishy. So I found another one (and there is considerable size difference between the two).
https://androidfilehost.com/?fid=529152257862698997
MD5 of this file (check to confirm after you download using win-md5 or something like that): 36be7f4b14082b2e0cfd9d8f7c3b08d0
I forgot where I got this link. But it seemed more reliable than the one from Redmi forum. And this is the one I've used. I'll try to find the source later. You have to use TWRP designed for the model of the phone you're using. Using incompatible one could brick your phone (though supposedly not permanently). Anyway, if you find another TWRP source, make sure it specifically mentions that it's made for Redmi 3S.
Before you proceed, to connect the phone to PC, you'll need ADB and drivers. If you have Android Studio, you already have them, but for most people it's too big of an install, so instead download small package here and follow instructions to install: http://www.cyanogenmods.org/forums/topic/install-adb-fastboot-windows-drivers/
Once you got the drivers installed, go to the folder where adb.exe is and place the recovery.img there (it's the one from the TWRP zip, it could be named differently of course).
Then open up command window (cmd.exe) and go to the folder where adb.exe is.
A) Type this command to put the phone into Fastboot mode:
adb reboot bootloader

If your phone asks “Allow USB debugging” say yes.
B) Then transfer TWRP image file to the phone via the following command:
fastboot flash recovery recovery.img

C) And lastly, tell the phone to boot into it:
fastboot boot recovery.img

If you skip step C, the phone will probably delete the image when you reboot. Some tutorials skip it, and that doesn't seem to work
First time in the TWRP, it'll ask if you want to "Swipe to allow Modifications". You want to do this if you want to root.
Now once you've done that, you MUST “Disable dm-verity“. If you don't, the phone will enter into infinite bootloop and the universe will collapse (or so I heard). So I disabled it! Go to Advanced Settings and there it will be.
Now once you've done that you should be good to go. Reboot it into normal system mode and prepare yourself for Rooting!
Once the system boots, you should confirm that you've indeed installed TWRP.

To enter TWRP recovery:  Shut down your phone. Then hold Vol Up, Vol
  Down and Power, at the same time and as soon as MI logo shows up,
  release just the power button, and when TWRP logo shows up release the
  other two buttons also, and wait a little and it'll start up with the
  menu. Although for me also works releasing all buttons once MI logo
  shows up.

Now to the actual rooting.
Having done the previous things, this part is actually pretty easy!
Go to the official SuperSU site: http://www.supersu.com/download
The SuperSU site is hard to understand, though what you need to do is really easy. Just need one file to download there: "Recovery Flashable.zip" (latest) and copy it to your phone. Or better yet, just download it from the phone's web browser. (They also have APK files on their site, you don't need them)
The browser will save the file to your Downloads folder most likely (check to make sure it's there once transfer is complete)
Now reboot into Recovery Mode (TWRP)
Click Install
locate the zip file and Swipe to confirm flash.
Now the installation process will start and it will reboot the phone a few times while doing it, so be patient and don't fiddle with the phone, just put it on your desk and look at it.
Once it's all done, It'll ask you to reboot, and once you do that your phone should be rooted! An app was also installed during this process called SuperSU, it is a root manager that will manage which apps get the Root permission. To confirm you have root, you can enter adb shell and  cd /data/system  and try to create a folder there, only root can do that. (No need to download extra software to check if you have root.)
That's all. Next you'll probably want to remove some bloatware. I'm making a guide at the moment and will post a link here once done.

HTC M8. Can't explore files via windows.
My phone is connected over USB to Windows, where it is only recognized as 'Android Phone' under the unspecified tab.
On the phone, no notification of USB connections is given at all, except that the phone starts charging. I've tried to enable MTP over USB, but I can't seem to locate the 'Use USB for..' menu anywhere.
Searching for usb in the settings menu turns up nothing.

You should be able to tap the USB notification, which should lead you to the correct menu to switch between MTP, PTP etc. If not, check in Settings › Storage.

@Izzy There's no USB notifaction. In settings > Storage & USB there are no options related to USB at all :/

In Settings › Storage, have you hit the "overflow menu button" (the 3 "stapled dots" in the upper right corner)? That should pop out an option named like "USB Connection".

@Izzy Regretfully, there's no such option. The overflow only lists Help & feedback

I get some ads that keep popping up. I got fed up of it and clicked the opt-out button next to it. That opened a tab on Chrome, and thats this:

Can anyone help me disable these ads? I don't know why these ads came in the first place.

@Izzy those questions do not help me. My phone isn't a Samsung, its a Lenovo K6 Power. I do not have the Premium Wallpapers installed either.

The phone doesn't matter. Have you noticed it's exactly the same screen shown there, and its exactly the same URL? Moreover, the answer given by Matthew isn't device specific either.

Does integrating an update into ROM remove the older application version?
I have a phone with very limited storage capacity, so I opted for integrating some updates into the system partition, the problem is that it quickly ran out of space in that partition too.
So, I'm wondering whether the previous versions are also kept somewhere and how to remove them. I'm using this tool to do the update integration, and it seems at some point to be doing a backup of something, I guess it's the user's data but I'm not sure.

The old versions are removed (overwritten actually)... Remember that changes version in the /system partition could cause your device to be rendered unusable if you perform a factory reset at a later date.

@acejavelin thanks for the heads up, it already happened to me with this phone, I guess I'll need to keep a stock ROM image at hand before trying a factory reset again, just in case.

Fixing / Backing up phone that doesn't get recognized by pc and is stuck in a boot loop
I currently have a OnePlus One, which since this morning seems to have broken, it's permanently stuck in a boot loop where it shows the OPO logo, but stays there until the battery runs out.
I want to make a back-up and re-install the firmware, however my PC doesn't recognize it when running adb devices or fastboot devices. I'm sure I have the drivers installed on my PC (which the original download links are now all dead by the way), as I've connected my phone before.
Does anyone know how I could either:

Transfer my files to my PC
Get my PC to recognize my phone

I looked in the following locations for help:

What permissions I shouldn't block with my Privacy Guard?
I have installed LineageOS with "stock" version of Open GApps. I noticed Privacy Guard can control which apps have access to which information. I have changed nearly every permission to "ask me" and my system refused to cooperate (was freezing immediately after booting, see similar problem).
Therefore, there must be a critical set of permissions that must be enabled (in Privacy Guard) in order for the system to work properly. What are those permissions?
I am using LineageOS v14.1 (Android 7.1.2).
Note: I do not want to troubleshoot my problem. I need an answer saying "if you block this information for that app or that information for that app your system will stop working". I have solved my problem by flashing the phone again, so I'm safe.

Did you apply these changes to system apps too? If yes, that may be the cause of your problem. If you denied Google Play services permissive for instance, it being a core component of OS, you can guess the consequences . Unless you have a deep knowledge of these permissions impact, it is best to leave system apps alone.For user apps  it is safe to apply community updated permissions ( pro version ) and fine tune as per needs

@beeshyams no "pro version" an, I'm afraid, no "community permissions". OP asks about CMs/LOS' built-in "Privacy Guard", not about Xprivacy :) But apart from that: full ack, only touch system apps if you know what you're doing.

@beeshyams Yes, I have changed system apps permissions, but what I did does not matter (see added note in question). I don't think Google Play services are necessary for LOS to work, since LOS is not shipped with GP services. Also see this - they don't say that GP services are crucial to the system, just for the extra apps. And they can be "disabled" even on non-rooted Android.

My mistake - was mixing up with XPrivacy. Sorry. @izzy. Thanks

@styrofoamfly Though GServices might not be essential, there's one problem in your context: they themselves think they're very essential, and are allowed everything – so if you forbid them access to something they see that as "hick-up" and retry until they succeed. Which they of course never can. Thus their constant hammering is slowing down the system. At least I assume that's what happens in your case: you cannot confirm/reject requests in the frequency they happen. "Ask me" delays the operation until user's answer (or timeout). Rather app specific than permission specific.

Photos how to get rid off the home screen
Hi can anybody help just got the android tablet,we have been looking
For a car,so to save photos it tells me add to home screen ,which was  good but now we have a car ,how do I get rid of the photos from my home screen ,would be glad of any help .thanks Alan

To remove a shortcut from your home screen, just hold down your finger on it until a little remove label appears. (It probably has an X icon or a picture of a rubbish bin, but that depends on what tablet you have.) Without lifting your finger, drag the icon over to the remove label and then let go to drop it there.

Where is my storage?
I have 12gb on my phone storage, but only half is accounted for. How can I reclaim my storage?
My phone is a OnePlus 1 running CyanogenMod. I get it that the extra space is taken by some system files or cache. The amount of space used by the system keeps going up (Half the storage space now) and I want to figure out a way to clean this. I tried several "cleaning" apps with no success.

Storage (click image to enlarge)
Update: disk usage shows me 4gb used by system, no details or options to delete. Any idea how to reclaim this space?

Unusual question - what font is that on the phone? It looks really nice

Related: My space used and free space doesn't add up, also see What can I do to manage my phone's internal storage? / Why does Android show more space used in internal storage than what adds up in the details? What device is it? Which Android version?

Possible duplicate of My space used and free space doesn't add up

It doesn't usually add up properly.  Once you take into account system data, the OS, cached data (from apps, email clients, web browsing etc) it goes down pretty quickly.  Although it's not normally that far out!  What phone are you using?

What is this notification icon with a person's head and a share icon?
I'm just wondering if anyone knows, what application this icon goes with. It was a screenshot from someone else's phone, so I can't just pull down the status bar and check.

This is not an app icon, this is an Android built-in function for sharing content over Bluetooth, Wi-Fi direct, NFC, on Social medias, etc. Also called Direct Share on Marshmallow.


text:
Which apps are placing icons on statusbar?
I have LineageOS with Android 7.1.2. I reinstalled at once everything I used to have. Now I have 3 icons on statusbar reporting battery charge.
I'm unable to figure out who is placing them. Is there any way that informs which app is placing icons on statusbar? If I could edit it, much better.

are they on the left? then swipe down and long press the notification

Notification History displays a list of all notifications originating from apps and you can compare the app icon to that in your status bar to track down the app. You can even see the time stamp of each notification app to help you. As you can see from the pic , it shows notifications from System UI also ; that may help you identify the culprit for your battery charging icons

Once you track the app, you can try revoke it's permissions to show up in status bar. If these icons don't show up in safe mode, it is app based and of they do perhaps you are better off searching for a solution in your device / ROM forums

Thanks. So, these left icons are notifications? And what are the right ones?

Indeed left side icons are related to notifications and I just need to acknowledge them. What about right side icons, is there a way to edit what appear there?

Ok I'm gonna try there. I'm using RessurrectionRemix on Note3. It wasn't hard to root, vanilla SuperSU did the trick.

3D using VR headset in Nokia 3
So let's say I have got a split screen 3D video. My Google search results told me that if I just play it in VLC in my Nokia 3 and use a VR headset, I will get 3D experience. However when I play 360 degrees VR videos from Google, they are distorted and not rectangle in shape. So I am afraid that when I play rectangular side by side 3D videos, the videos will be distorted and the sides will be missing. So what should I do to convert the side by side video to the distorted VR like video? Is there any app or something?
I have not tried them yet as my VR headset has not yet arrived but I want to have everything ready as soon my VR arrives. (Basically I have decided to wait for some time and if I cannot watch 3D with cardboard I might not buy it)
Screenshot of how video should look like when seen by google cardboard(i.e. what I meant by distorted video)

And this is what 3D split screen loos like and I intend to convert this to above form :

Use a player like 3D VR Player to play the video..
There are many such VR Player apps in Play Store (search for it). All you need to do is download the right one you need.

Now that I have my VR headset, your app is not working. It is not callibrated and has no option to callibrate. I need something to scan my QR code and callibrate.

What is your VR model?

Here's the VR headset and the QR code :
https://teslaandi.wordpress.com/2016/01/22/vr-box-2-0-qr-code-and-vague-review/
And yeah thanks man for all your time.

Also note that I got it callibrated on Google cardboard app but that doesn't  not play 3D videos

Recovery and Download mode on a device
On a dated device, Sony Xperia Tipo, I can not get the recovery mode. Yet I remember that I used it some years ago, but also with adb reboot recovery it continues to start in normal mode. I have just unlocked the bootloader, and before of that I rooted the device using the Kingroot app. Possible that has this app wiped the recovery partition?
Also I can not find references to start in download mode.

As you mentioned that the device didn't boot to recovery, it is most probable that the recovery partition has been wiped off. Have you tried reflashing the recovery image?

@bikalpa Can you explain me the reason why it could have been wiped off? Moreover I have no idea where I can get the original recovery, I had only seen the firmware (I guess the original Sony) on xda ( https://forum.xda-developers.com/xperia-j-e/general/ftf-xperia-ftf-firmwares-collection-t2001567). Can you tell me where I can find it, please?

Can't you just reflash custom recovery like TWRP to get into recovery mode? As far as the reason is concerned, I have no idea, but maybe unlocking bootloader wiped it off.

Try rebooting from terminal within the phone (use terminal emulator) ,first ask for root permission using the su  command then type reboot recovery see if it works (adb reboot recovery might not work on some OEM android builds due to restrictions)

@lord-ralf-adolf I do not currently have the root. I had uninstalled Kingroot and ran factory reset. I have only the bootloader unlocked. Maybe is the unlocked downloader the reason of the lacking of recovery mode (i.e. the recovery partition is still in memory, but the bootloader doesn't recognize the combination volume+power so it uses ordinary boot)?

@bikalpa I would like the original Sony recovery. The xda firmware I mentioned is the original one in your opinion? And is the recovery partition included in the firmware?

Recover incoming SMS
Accidentaly few weeks ago I make my phone bootloop. So to fix this I reinstall the ROM image (including recovery image and fastboot image). I realize that there are some of my important SMS haven't been backed up. So Is there any way to recovery the deleted SMS in my case? note: I already try to use Windows App like Coolmuster Lab.Fone for Android, dr.fone toolkit for Android, disklab_for_android but not helping at all.

SMS messages are stored in a system database file, if you performed a factory reset, which typically occurs as part of a factory image flash, they are not recoverable.

It's not fool proof and you'll need to figure some parts on your own, but:

Create a backup of /data in recovery
Unpack the backup on your computer
Find your SMS app in restored /data/data. Most likely the app name is starting with com.android..
Flash your new system image
Using adb, use ls -l /data/data to display permissions of the SMS app directory. Note the permissions.
Restore the SMS app directory using adb or Android file manager with root permissions
Change owner/group/permissions to be the same as you noted earlier.

Your SMS should be back at this point.

This would not restore any messages... The messages themselves are not part of the app, but are maintained in a system database. Restoring the app, or removing it, has no effect on the message store itself.

Good point: he then just needs to find the right file to restore -> https://android.stackexchange.com/questions/16915/where-on-the-file-system-are-sms-messages-stored

How can I use multiple accounts with Telegram?
There is a question here but that is for Ubuntu on PC.
I have the same question for an android device.

Is there a way to have two copies of telegram app in Android each with
  a different account?

I'm using the version Kitkat 4.4.

Parallel Space is often quoted to be preferred app for running two copies of same app. Be aware that there are permissions issues with this app. I never used it but you may like to try. If it works , let me know to post as an answer

@ beeshyams thanks and what about app cloner?  do you know anything?

Sorry. No idea about that app

Have you tried Disa unified messenger im with telegram plugin, I have used app cloner but not with telegram, so there are chances it may or may not work, generally it won't for applications that use Google play  services.

Use the Parallel Space app. Using this app, you can run more than one copy of almost any app. Here is a link to the app: https://play.google.com/store/apps/details?id=com.lbe.parallel.intl

seems it's the best choice but the problem is i'm living in Iran and I can't buy apps on Google Play (because iranians don't have access to international credit cards) and I just can download free apps. It seems that no free app can do the task completely. Thanks any way

Parallel Space is not a completely paid app, it offers in-app purchases. Do you really have to purchase this app for installing it in Iran? Because for me, it's not so. I can download it without purchasing.

You can get the apk of app from reliable source and sideload

@AnubhavDas Google play store says that the app is not compatible with my device. I don't know. maybe it would be downloadable but since I can't purchase, I can;t have access to all the functionalities

@beeshyams  what do you mean?

I'll see if I can download the free app and if it's enough to fit my needs

@sepideh If Google Play Store says that the app is not compatible for your device, it means that the app is not compatible with the version of android you're using, i.e. KitKat 4.4 & it has nothing to do with the pricing of the app.

TL;DR: It's available officially.
From version 4.7 of Telegram (December 30, 2017) it's available officially in the Android app.

Multiple accounts
The Android app already supported multiple themes, so it had to go further with 4.7 by supporting multiple accounts. You can add up to three accounts with different phone numbers to your Telegram app, and then quickly switch between them from the side menu. Notifications will keep coming from all accounts, unless you change this in the Notification settings.

I can't pair my activity tracker (Mi band 2, xiaomi) with my tablet/app (Android 5.1 ).
According to BLE Scanner app: no nearby BLE devices, 'peripheral mode not supported in your device'
When I open the app (Mi fit) : discoverable is off
How do I fix it?
Note: I got the tablet for free and there's no name or brand, only "rockship 791"

Does Mi fit connect to the Mi band? If not try to install an older version, I found that while trying to configure smart unlock, as with newer version of the app I could not find the device on an HTC one M8

BlueStacks APK Install Error : INSTALL_FAILED_OLDER_SDK
So i was trying to install an APK file on BlueStacks App Player and then this error came up :
[INSTALL_FAILED_OLDER_SDK]

Can someone help Me?

Maybe you're using an old Android version of BlueStacks. What Android version is your BlueStacks running? (Wondering why this error? Each application has a minSDK field, which describes the minimum Android version to run the app.)

The app you're installing is meant for newer Android versions than what's emulated in the BlueStacks environment. If there's no new version of BS available, you will either need to give up on the app or use a different emulator.
There are workarounds involving modifying the manifest of the APK file to be installed, but since you don't really know what APIs the app will actually use, shoehorning it into an older SDK won't always work.
