Screen issues - Xiaomi Mi A1 Questions & Answers

Hello folks, I'm having annoying issue with the screen so wondering if anyone can try to help me or has encountered similar issue.
The issue is that the screen wakes up randomly without touching it, as the power button was pressed (without notification). This started after updating to april rom.
Here is what I have done so far: turning off/on ambient display, turning off/on adaptive brightness, remove sd card/sim card, returning to march update doesn't resolve this, factory reset, flashing the latest stock 8.1 beta rom...
Interesting thing is that the issue is NOT happening when booted to safe mod, which makes me believe that this isn't hardware failure ? Or am I wrong ? Anyone with an idea how can I try to resolve this ?

Application can cause wakelocks - wake phone's CPU to do its work or just turn on screen. Especially 3rd party apps from Google Play cause this, maybe there is an app causing your phone to turn on. Use BetterBatteryStats (with ADB commands) to see which apps wake your phone.

Phone keeps returning to home screen - h/w issue?

My phone has developed a very strange problem where it keeps returning to the home screen from other applications. The screen also turns on itself from standby.
I have tried wiping it clean and flashing it with the stock Rom from the SD card. I'm beginning to think this is a hardware issue. Has anyone else had this problem? Any ideas?

[Q] Random Reboots and Screen Wake

My nexus 7 has been randomly rebooting a lot lately. I have no idea why. I haven't even rooted or unlocked the bootloader or anything on this. I haven't installed any new apps for like a month probably so I don't think it's an app.
Also, my screen wakes up on it's own quite frequently. See the attached screenshot. Notice how often the screen is on, there's like a million lines for it turning on and off. And this is while I'm asleep and not doing anything with it.
I can't think of any app that causes this because I haven't installed any apps in forever. Not a root or unlock issue because I haven't done either. I have a case with a magnet in it to turn the screen on and off. I don't think it's that because I took it out of the case and I still saw it happen.
Any ideas on what is causing this?
I had one too hope its only 1 and screen wake maybe caused by some application you have installed, try reinstalling rom and without installing anything you will notice no screen wake

[Q] Screen Black / Auto Powered Off Frozen?

I seem to have the most bizarre issue that started happening last night. Ive been running XNote v3 and AEL kernel fine for a long time now.
Whenever my screen turns off (when i hit the power button or the timer runs out to turn screen off) The phone will after x minutes, either auto reboot or turn off (without shutdown animation)
It then remains off black screen and you do not know this unless you try use it again as you cannot power it back on at all, no sound and the phone is off as if you call you get voicemail.
Anyone any ideas what it might be?
I cant work out if it is software/ hardware related as nothing has changed software config wise and i have not done any updates.
I was thinking of maybe going to a stock kernel and see how that lives.
Its very easy to replicate and the only way to bring the phone back to life is to take the battery out.
If i am using the phone its perfectly fine, no reboots, freezes etc. Its only when screen is off.
OK since no one replied back but a lot of people viewed i thought i would provide an update.
Since factory resetting it
changing battery
wireless charging
removing sim
removing SD card
changing rom
changing kernel
changing back to stock
remove root
boot loader etc
all failed! a new replacement motherboard fixed the problem. i am unsure what caused the fault as it was working perfectly for over a month.

Phone randomly locks itself

Hi guys
I recently bought an OnePlus 2. With the original firmware, I experienced a very strange and very annoying issue: My screen randomly turned off (e.g. during a chat in WhatsApp). The screen turns off and I have to turn it on again by pressing the power button. Then I enter my PIN to access my phone again and it locks AGAIN. This happens like 10 times in a row, then I have to reboot the phone and it was OK again. I seriously don't know what triggered this issue.
However, recently I got pissed of because I tried to call one of my customers and as soon as I entered my PIN and tried to open the phone app, the screen locked again and I almost threw away my phone. Damned troll.
So I decided to try another ROM as I thought it was an OS-related issue. Now I'm running Exodus Android 6.0.1. I did a clean install and guess what: The issue came back on this ROM...
In my opinion there's only something both installations (my previous 5.1.1 stock ROM and my current 6.0.1 ROM) have in common: I've been using XPosed with Amplify, Greenify and XPrivacy. Other than that, I have no idea what it might be.
Have you encountered the same or a similar issue? If so, were you able to solve it? How did you solve it?
I just uninstalled Amplify, as I think it stops somehow the Gyroscope service, that's why it locks randomly. I'll check if the issue appears again...
I think I have good news for you guys: I guess I was able to locate the issue.
I noticed it always happened when I was holding the phone in the hand I had a ring on my finger. Then I found out the phone has magnetic sensors (for flip covers).
I downloaded the Xposed module "Magnet Sensor Control", the bug hasn't appeared so far!
I hope I was able to help you guys with my findings. This thread may be closed now.

YotaMirror turns on by itself

Hello,
recently I'm experiencing a problematic issue with my phone. After some time of using it, the back "always on" screen turns on by itself, mirroring whatever is on the main screen. When it happens, I have the same screen available on both front and back of the phone. What is more, a switch to turn YotaMirror on/off doesn't work and both screens remain active. To solve the problem I have to either restart my phone or click on any YotaApp that uses back screen only (like Chess or Sudoku) and start a game on back screen. It solves the problem for a while, but it appears again several times during the day, draining my battery and making my screen visible to everyone.
Is it a known bug? Is there any known pernament solution to this? What may be the cause of this strange behavior? I didn't install anything new recently when it appeared.
I'll be very grateful for any advice and help.
Yours sincerely,
Adam (bukimi)
