Fingerprint scanner stopped working - Xiaomi Mi MIX Questions & Answers

Hello!
Somebody with this issue? I installed and applied Nova launcher, and plugged Mix to a new charger (no idea if any of those things can have anything to do with it but they are the only new things that happened) and scanner didn't recognise my fingerprint.
Took me a couple of long tries to record it again.
Somebody encountered this issue? Any ideas?
Thanks

Camera not working, Touchscreen and accelerometer stop responding.

OK, like 6 months ago, my camera stopped working. Any application that tried to access the camera would force close or kick me back to the home screen. About a week later, it worked again for like a day, then stopped working again. I flashed different roms, but the problem remained. About 3 months ago, I switched to the JACHeroski rom, and my camera spontaneously worked again. After a couple of more weeks, it stopped working again. About a month ago, I switched to cyanogenmod, and the camera worked again. And now, again, it stopped working.
And now, I have encountered another problem. My touch screen stops responding to any input, and the accelerometer stop responding simultaneously at any random time. On some days, my phone works perfectly, on others, they stop working after a few hours, and on others, they stop working right after I turn my phone on. Sometimes, this happens while I am doing something on my phone. A reboot always fixes this problem, but it is annoying having to reboot my phone when the touch screen stops responding.
A few days ago, in an effort to fix all these issues, I unrooted my phone, and re-rooted, and re-installed the latest cyanogenmod. But the problems remain. I am pretty sure these are not hardware problems, not only because I never dropped or wet my phone, but because of all of these problems are occurring simultaneously.
Does anyone have any idea, no matter how time consuming, to fix any of these problems?
The camera issue is well known and due to a loose cable.
Hmm, I thought it was too much of a coincidence for the camera to work perfectly for a few weeks precisely when I flashed cyanogenmod, which I would think makes it a software problem. But then again, when my camera stopped working again, and I flashed cyanogenmod again, it did not fix the problem.

Mine is the same way. It works every now and then, but mostly doesn't work. I just haven't had time to take the phone apart and re-seat the camera FPC.

[Q] Tilt to wake seems to have stopped working

For some reason, tilt to wake stopped working. I have no idea why. It was working fine yesterday morning in the metro, but stopped working during the day. The watch is paired with a HTC One M7, running a stock Sense ROM. I've converted the phone to GPE back in December and the watch worked well, but now I reinstalled a stock ROM because GPE was draining my battery real quick and, again, the watch worked well for a couple of days, but now, nope. I tried resetting the watch, but no result. Is there any other way to figure out what the problem is without reinstalling every piece of software? I mean, I'd like to test the sensors to see if they have a problem or smth and if they turn up to be good, well, I might contact Google cuz something's not working. Yes, the tilt to wake option is enabled in the companion app.
So, does anyone have an idea of what I can do? I couldn't find any info on any forum
Thanks in advance :3

OnePlus 3T home button/fingerprint sensor stopped working overnight

This morning when I woke up I noticed my phone required my pattern lock which means at some point during the night it rebooted. After unlocking I realized my home button was completely unresponsive. Recents and back button work fine.
I've found a lot of information about this issue for the Oneplus 2 and tried some of those suggestions but they haven't worked so far. If I dial *#808# and choose Finger print test it says "The application cannot reach the android service for the sensor"
Has anyone had a similar problem and does anybody have any ideas how to fix it? I've read that factory resetting the phone has fixed similar issues but I wanted to try everything else first.
Btw I'm on stock OOS 3.5.3, unrooted, no modifications.

Have you tried rebooting again to see if that fixes it?

Yes I've tried rebooting and even system resetting. I just spoke with OnePlus and they said it sounds like a hardware issue and they will cover it under the warranty.

Moto G6 freezing after being unplugged.

Hello everyone, I'm just curious to know if anyone knows how to fix this issue: when I unplug my phone and shut the screen off right after, my phone simply freezes in the state that its in. I know its frozen because if I have my flashlight on it stays on and nothing responds (touches, buttons, fingerpring sensor, etc), but it will not freeze if I have music playing for some reason and the only way to get access to my phone again is to forcefully restarting it (by holding down power for about 10s, which is really annoying). If anyone can help me with this I would really apreciate it. Ps: my phone is a Moto G6 (ali). I know that doing a factory reset fixes it, but right after I re root it and install my apps it starts doing it again. Below is a screenshot with all my root apps.

I have this exact same problem. I have 2 moto's. It occurs on both of them. Never happened till I rooted.
You should disable all of those apps ( especially substratum) and see if the problem still happens. Then if it doesn't, activate one by one till it happens again. Then with the culprit found, look in internet if it has any conflicts to another app you have installed. If you find maybe they have like a patch to download or a modified version. If not you'll have to let one of them go. Or maybe there's no conflict with any other app and it's just that one misbehaving. Disable all other apps and let only the culprit activated. Does it still bug? you can try reinstalling the app or uninstalling it.

Question Fingerprint scanner not working

Hey everyone,
I was listening to music on Spotify last night on my Redmi Note 10S. I then turned off my phone and when I tried unlocking it, the fingerprint scanner wouldn't detect the fingerprint. I tried to make another fingerprint in the settings but it would not do anything. I thought it must've been a small issue and decided to restart my phone. Still Nothing. I need some ideas as to how to restore fingerprint functionality at home as I don't want to take it to a service center again.
If you have a solution please let me know.
Thanks!
