Bluetooth failed - Xiaomi Mi Mix 2S Questions & Answers

I gotta say i bought this phone with high hopes but so far it is a total disaster. My Bluetooth stopped working. It started with being unable to connect and having to restart phone but now even resetting phone and settings does nothing. Since it doesn't back up app data (except for some google useless apps) i dont want to factory reset. Anyone had similar issue?

Nope but it sounds like you need to factory reset whether you want to or not.

Bluetooth working perfectly fine here... No connection issues with my Smartwatch, car, Bluetooth headset and speakers. Hopefully a reset will fix it for you

[Q] A strange Failure to boot.

Hi
I am having a problem that just cropped up on a Xoom 3g running unrooted, Motorola Jelly Bean 4.2.1. I am using it on wi-fi only, no Verizon account. The unit will get past the M screen and then ususally hangs up when it gets to the screen with the expanding colored rectangles. Sometimes the home screen will flash up for a split second, sometimes with enough time to log in. In either case it is back to the colored rectangles shortly, even if I get it to log in. I can get to the factory reset screen during the boot and do a full factory reset reload the apps and settings. I have done this twice. It works for about 20 or 30 boots and then colored rectangles show up in the middle of a session and its back to the boot problem.
Questions:
Does anyone have a quick answer?
Will rooting and reloading Android help or it is a hardware issue?
Thanks for any help
John
Have tried a full factory reset without restoring your apps and settings to see if the issue persist?

It seemed to work ok with the apps installed for a while. There were a couple which were suspect and I did not reinstall after the factor reset. It could be a problem though. Maybe I will try the reset again with only a couple of apps. I am still undescided on the root and updating the OS.

Hi again.
I did some thinking and now I suspect the Bluetooth connection. I had enabled an app that required BT (Logitech Harmony Hub). I also enabled the BT but not the app after the second factory reset. I did another factory reset and did not enable Bluethooth. The unit has been running flawless as before. I did a little searching on the web and found a guy with an identicle problem but it was not clear if it was resolved.. Does anyone know know if this is a common problem and if there is a solution. I could not find anything elso on the web or in the formum that helped. If this is a persistant problem, I am wondering if a custom rom would help.
Thanks
John

Speakerphone auto on problem

Every time I receive a call my Speakerphone turns on by itself. Same when I make a call, it says that Speakerphone is on but it is not and work normally through the ear speaker.
Did clear data on Google dialer and same thing but at least the Speakerphone icon shows me that it is on when before it didn't.
I'm rooted but still everything else is stock. I had some apps disabled but re enabled them and updated and still the same problem.
On my first attempt to root I managed to stop it from booting the OS so I flashed the factory image and on my second attempt to root everything went fine. So maybe something went wrong there.
Does anyone have any idea beside factory reset or using the flash the factory image?

try answering or dialing a call with headset(handsfree) plugged in!
Lets see what it does!
When I plug in something like a wired headset the Speakerphone doesn't auto on. But it does the same thing again when I unplug it.
Sent from my Nexus 5 using xda app-developers app
Well I ended up doing a factory reset and it all works fine now. I will personalize my N5 again and monitor it.If it comes back I will let you know what I did to get that problem.
I found what is causing the problem.
It is the app Elixir 2. It must have a but somewhere because of Kitkat.
I absolutely love this app because of its versatility so I already contacted the developer.
Hope he gets back to me soon.

Pixel only wakes after 10 - 30 secs, audio not working

Since a week or so I have a few problems with my Pixel.
I wanted to listen to music via headphones but it didn't work. I thought my headphones were broken, so I connected them to another device but they weren't. I rebooted my Pixel and didn't think of it anymore.
Later that day my phone would only wake up after 10 - 30 seconds after I pressed the power button. Unlock via fingerprint didn't work. I found out that rebooting solved this issue for some time (1 or 2 hours) but after that time I got it again.
I contacted Google Support and they proposed a few different solutions. One of them was safe mode but after a few attempts I got the issue even in safe mode. Another solution was (obviously) to wipe and re-install the firmware (I am on stock). So... This didn't work as well. Got the same issues which are:
no audio output (neither via jack nor speakers) --> so I can't use the telephone, I can't send voice messages, I can't record video and so on...
phone sometimes only wakes up after a short waiting time
I will try one more re-install and if that doesn't solve the issues I will try to get a new one...
Any ideas about that?

Do you restore from backup after resetting/wiping the phone?

I restored apps and settings and everything else that is saved there via my Google account.
OK, I did another re-install following the official instructions. Audio (and everything connected with it: calling, video camera, YouTube, etc) is still not working. Haven't had the issue with the lock-screen though.
Anyway, tomorrow I will try to get my phone exchanged. I believe it's an issue with the hardware...

What if when you reset the phone, but this time try not to restore the phone and instead set it up as new. Just to see...
You've rebooted, booted into safe mode and done a clean install. There's not much more you can do so I'd send it back.
So guys, I got my phone exchanged for a new one. I think the key word was "audio/mic problems". Thank you for your replies.

Its a know problem with the first batches of the Pixels.

A8 keeps putting whatsapp asleep nomatter what setting I change.

So I have had this problem before a year or two ago, I tried everything and had to reset my phone to factory settings to get it fixed. The problem is now back and I'd like to avoid having to reset the phone as its just a huge pain in the ass to set it all back up. I get notifications late from whatsapp and it keeps losing connection to webwhatsapp (wifi or via 4g). Only way to reconnect is to unlock my phone. I have checekd all the settings, reinstalled whatsapp and the problem occurs out of nowhere as I didn't change any settings in my phone, didn't update my phone.
I'm hoping a wizard here has any suggestions as a last resort.
Kind regards, a desperate stranger.
edit: running android 8.0
edit2: reset the phone and the issue is still there.

Stereo Bluetooth Earbud issue

Hello all, I hope this message finds you well.
Recently I bought a new pair of TWS earbuds, BlitzWolf BW-FPE1 and I'm having trouble connecting and playing sound in both of them at the very same time.
Actually when I connect both of them in the smartphone, I can see them connected at the bluetooth screen and I can also see both of them as available options to play audio from the Android sound settings. But as this is a pair of TWS earbuds, both should be connected together and play stereo audio.
What is actually happening is that this Android version (and I presume this is the reason) does not allow me to select them both at the same time. I can only use one of them at time: the audio will either play in the left OR in the right side. In addicion, I receive both left and right side of the audio in just one part of the earbuds.
And just to make sure the earbuds are working perfectly, I've tested it on a Samsung M51 running Android 11 and the latest One UI version (can't recall the version right now) and in the Android audio settings there were on screen a radiobutton to select both of the buds at the same time.
Can someone really confirm that this is a limitation in Android 11 stock version or if there is any kind of workaround to make the earbuds work together?
Thanks in advance!
Try clearing the system cache.
Try a network reset.
A cheap trick that fixes a lot of issues.
If that doesn't work try reinstalling their app, try clearing the data first. Reboot.
Check connectivity setting in settings.
Check bt settings in Developer options as well.
Any other 3rd party sound apps? Try in safe mode. Any you uninstalled*?
Try a hard reboot (simulates pulling battery).
Do not do a factory reset unless you did a major firmware upgrade without doing a reset.
Find the root cause, otherwise it's likely to reoccur.
Play with it... you will find the cause.
Google search for same issue on that brand of device (Motorola), include other OS's/device models in those searches. More than likely you're not the first.
*if an app changed hidden user settings, a factory reset may be needed. This is rare but can happen. Poorly coded ones sometimes will not toggle back hidden settings to their default value.
Sometimes reinstalling the app can allow you to change that value in the app's settings, then uninstall that app again

First of all, thanks for replying!
Well, these earbuds do not have any particular app for configuration or use (and I as long as I looked in the user's guide and Playstore, there is no particular app for them).
I've already checked settings regarding to Bluetooth on Developer options and changed some of them after sometime researching on Google, restarting the smartphone afterwards but no one solved the problem.
I'll take another look into system cache and network reset, hoping this will really solve my problem. Otherwise, the only explanation would be a limitation on the stock version of Android v11.
Many times a network reset is all that's needed.
Clear system cache.
I hate Android 11 but haven't seen this as being one of its known issues.
I have the same situation. the online manual solve it for me
Recover to Default Setting​When Bluetooth is not connected and in a single headset state, press the touch key 5 times to clear all pairing information, the red and blue lights flash 3 times at the same time, put the earphones in the charging box, then you can pick up the left and right headsets from the charging box for -MS pairing.
