Xiaomi Mi 9 Lite screen flashes on wake up - Xiaomi Mi CC9 / Mi 9 Lite Questions & Answers

The phone in question is with 12.0.5.0 (QFCMIXM) Android 10, Xiaomi Mi 9 Lite.
The screen seems to flash bright color on wake up, after a certain amount of time after I lock it and leave it idle (10 seconds). Then I pick it up and unlock, the same as in video happens.
It does not occur if phone was previously used, and it didn't go into what I call deeper sleep(probably turning off the screen completly?)
This issue is with those newer updates, didn't happen before, although might be coincidence.
Your opinions? Did it occur with someone else?
Thanks in advance.

I had the same bug on version 12.0.5.0 guess its software releated.

Lots of issues after updated to Android 9 Pie (Mi A2)

After my Mi A2 was updated from Android 8 O to Android 9 P, I have to face lots of bugs and some serious issues. Although I already tried factory resetting, it doesn’t help. Many A2 users also face these issues.
1. Portrait Mode – Unable to focus on any other subjects, except a subject in the middle of the frame. That means whenever you touch on the screen to focus, focusing does not work for you at all. This is one of most serious issues for users who love photography.
2. Fingerprint Scan – Significantly slower scanning speed. Very annoying.
3. Screen Brightness Dropping – When I was on Android 8 O, I always adjusted the brightness scale to 30-40% and it’s bright enough. But now, for Android 9 P, I have to slide the scale to 70-80% so I can see the screen clearly. (Adaptive Brightness already turned off)
+++ There's an explanation that this screen brightness change is not a bug. Find out more here: https://forums.androidcentral.com/g...ubt-about-display-brightness-android-pie.html
Thanks @Varun.Shanbhag for the information. +++
4. Heating Issue – I’ve noticed that while charging the phone, when it was on Android 8 O, the temperature never got more than 39°C, but now, on Android 9 P, it sometimes gets to 41°C. (Refer to the app ‘Ampere’)
Moreover, when using camera, it gets hot too quickly.
However, I am not sure if there’s only me facing this overheating issue.
It is likely to be caused by CPU freq. issue stated in the following thread: https://forum.xda-developers.com/mi-a2/help/little-cpu-stucks-1401-mhz-min-freq-t3851184
5. Touch Screen – Touch screen seems to be less responsive than before. I can notice its latency. Sometimes I have to double tap the screen to get something done, because the first tap does not respond. (It can be easily noticed this issue with back button)
6. Lower Audio Volume – Some users say that they're facing lower audio volume issue when using earphones or headphones.
7. Face ID - Face ID doesn't work stably, it sometimes works and sometimes does not.
8. Front Flash Issue - front flash doesn't work when I turn it on in camera app. (But it works when set it as 'Auto')
9. Black Banding on Camera Screen - There're black bandings appear on the screen while using camera app, they look like signal noise appears on TV.
10. Camera App Crashes - Camera sometimes crashes, for example, the camera app says "Camera Error - Can't connect to camera" when I switch the camera from back to front in Portrait Mode.
11. Whole system seems to be less stable than it was in Android Oreo.

I hope all issues will be fixed in the next update.

I'm not sure about beep and screen randomly wake up, but the laggy LED pulse happens to me, that makes me annoyed sometimes ?
I also found that the LED issue has appeared since Android 8 O.
yeah the laggy led looks so cheap and retro like it was used in the last century ???
Hey guys, i just updated to pie December update, and the wifi tethering band locked to 2,4Ghz, any way to enable the 5ghz?
Really considering flashing the custom Pixel Experience ROM. Having a lot of bugs on Pie. Did the factory reset. None of them gone.
Any suggestions ? Should I just go for Custom. Or should I wait for next update ?

About the heating problem probably your cpu stacks at 1401 mhz when charging. Check it with cpu spy. This was happened to me with pie.

There's no this issue happens to me, I can switch between 2.4 and 5 normally.
BTW, try finding out this, in case it can help.

I think Xiaomi should fix these bugs ASAP, seems there're too much troubles here, as if we are using extremely unstable buggy custom rom LOL.

Thanks for your information, I've added it to the list. I also hear about Face ID issue on Pie, so you can be sure that there's not only you are facing haha.
I feel kinda sad with this update. We should report all the problems to Xiaomi as much as we can, just hope the dev can hear our voices.

Oreo is ok, i have downgrade my phone after some hours using pie. Pie for me it is in early beta.
How can we report about this ?
Gps problems
I'm also having issue with lags. Fingerprint scanner is lagging from time to time.. Overall daily task from switching apps to bring back to home screen also lags.
Disabling adaptive brightness seems to help improve the lag so far...

I just got my Global A2, 4/64 two days ago. Updated to Pie and have Dec Patch.
1) Portrait works fine. I can focus on any part of the scene and that subject will be in focus. Works quickly and reliably.
2) Fingerprint scan is quick with zero issues holding my finger at any angle. No lag whatsoever.
3) I went straight to Pie, so had zero experience with Oreo on the A2, but screen brightness behaves similar to the Moto G5+ that I had before. Adaptive brightness also behaves the same.
4) I never checked the phone with Oreo, but when charging on Pie, the phone feels cool to the touch. Cooler than my Moto G5+. BTW, I am using the OEM Moto QC 3.0 charger with the A2.
5) Touch screen is as responsive as my Moto G5+ and my Wife's Moto G6.
6 and 7) I don't use headphones or Face ID.

Everything is working perfectly. No lag choosing focus points in portrait, no lag using the finger print sensor, no lag using the screen, adaptive brightness, heat issues etc.? That all the behavior I am seeing would be better with Oreo?

Hello
I was on Oréo before and I did not notice any difference in the use with Pie, I am very fond of this version (sorry for English).

K20 Pro Animation Glitch

Hello buds,
I'm experiencing weird glitch on my K20 Pro (Chinese version). I have my phone for a while now, and I never noticed this thing. I'm not sure if it came with latest EU update (9.8.22), or not. I would like to know, if someone is experiencing similar thing.
But to the point...
When u re waking up the device, for a second ur lock screen is changing from blur to focused. The issue I'm about to talk happens, when I'm using my fingerprint, before wallpaper becomes focused.
The strange glitch will be visible in the video. At the beginning I was afraid that it's some kind or screen artefact, but with every application left opened (before locking screen) it is different. It looks like parts of apps re strangely stretched. When I tried to turn off all animations (also on video) the problem stopped, but then it came back in completely diffirent place. Literally for a millisecond, when I'm about to pull down a status bar.
It is not something really important, because I can bypass it by waiting till lock screen is focused, or by unlocking via fingerprint on off screen. Still, I'm a bit worried, so any answers will be appreciated

Proximity sensor doesn't work in call. Autobrightness sensor also glitch.

Currently using PixelExperience Plus ROM. Was using HavocOS before this. There were similar issues in both the roms.. The proximity sensor just won't work during calls. Phone needs a restart to fix this.. goes back to problematic in a short while..
The autobrightness sensor issue is less frustrating.. waking up the device the brightness gets stuck at about 50%. The slider does nothing.. locking the screen and waking up again solves it. Minor issue..
But.. does anyone have a fix?
Same problem here with latest oficial rom. Randomly screen goes black in a call although the phone is on a table.
Same problem here
Why do Xiaomi seem to have such a problem with proximity sensors?
The one on my Note 7 doesn't work properly and a google search reveals complaints about sensors on many models.
It's not as if they are rocket science any more.
Could this also be the reason when I receive a call the phone screen on some occasions didn't even light up and I have to double tap to see who's calling. I really hope it's something they can fix.
Did anyone get a fix? I still have this goddamn problem! Even with the latest evolution x rom or pixel experience rom (tried the latest version released like days back for both roms). This problem started right after I unlocked my bootloader and flashed a custom ROM and the problem is present in EVERY custom rom that I've tried. Please help me out with a fix as this is really annoying and the phone is practically useless. As soon as I make a call or get a call my display simply shuts down and doesn't switch on until 30 secs after the call ends. So my display is basically off for easy 2-3 minutes. Can't use my phone then. This sucks when I've dialled a wrong number or want to cut the call myself because I can't do any of that!

Xiaomi Mi 9T Pro Middle part of screen not working

Hello,
I bought the MI 9T Pro, and during my tests I've observed a weird issue.
When dragging the finger vertically on the screen , exactly in the middle it stops working. Mostly is observed when trying a paint type of app, is not recognizing the fingers when arriving in the middle of the screen. sometimes it works.
I tried doing a reset to factory settings but it didn't helped.
The phone has MIUI 11, i can't rollback to a previous version like MIUI 10, as i think this is a software issue and not a hardware one.
Any advices?
Kind regards.
Screen record in the miui testing app & post
(*#*#6484#*#*) -> Test touch sensor
Or can even test in apps like display tester or Antutu benchmark
Hello, i tried also this method. The test is assed but when nearing the centre of the screen i can see how a diagonal line goes for aproximately 1 centimenter straight vertically an after it passes the center goes back to drawing diagonally. A made request also to Xiaomi global support. Gave this advice and also update to the latest patch. Still didn't worked.
In the end i returned the phone and buyed a new one.
Kind regards

[MAYBE FIXED] Proximity sensor on Redmi Note 7

Hello everyone,
A few days ago I installed the V11.0.4.0.PFGMIXM firmware and no longer face the Proximity problem anymore.
Just download and flash newest Firmware You can download it at here: https://xiaomifirmwareupdater.com/firmware/lavender/
perfect, thanks for sharing, excuse me, after doing this do you know if it also solves the GPS location problems?

I don't meet any problem with GPS location before and after flash this firmware.
I just started experiencing a proximity sensor issue on MIUI 11, EU version 11.0.4.0
It occurred a few times after longer phone calls (more than 10 mins) when I removed the phone from my face, the screen would not light up. Neither the lock button nor the fingerprint sensor would wake it up, and I had to wait for the other person to hang up. Or maybe it only reacted to the lock button after 5 seconds or so.
I don't remember this happening previously. Is this something you guys have experienced?
Same problem

I faced same problem and i never paid attention to it. Now and I'm reading your post, i come to realize that the redmi-note-7 has a sensor problem and i have a miui 11.0.4.0 global version
I have heard about other people having proximity sensor issues on earlier versions of MIUI, also different editions (China, Global, EU). I've even advised some of them to re-calibrate the sensor through the service menu. I've been using the phone for 9 months now, I believe. I've updated it regularly and never reset it to factory settings. If this keeps up, I'll try re-calibration. If it doesn't disappear with the calibration or the next MIUI update, only then I'll consider factory reset
Hello
How I have Redmi Note 9 Pro MIUI 11.0.4.0, how can I turn off the proximity sensor? I have the screen problem other people are mentioning above
