Screen issue - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

Hi
I have a kind of green tint issue. My phone works fine, but the screen distorts red,blue,yellow partially. THe range of distortion looks like a waterfall. Anyways when i reboot my device and login for the first time there is no distortion, but the second login it starts getting distorted again. Is there anyway i can fix this?
Info:
ROM: DotOS 5.0.0
SELinux: Enforcing
Kernel: 4.14.196-IMMENSITY
Android Version: 11
Just to clarify it up, no i didn't overclock my screen or something.
The issue is also present on MIUI, just a bit less visible.

[Q] Dark Images and Scratchy Music

Hi guys,
I am facing some pretty weird issue with my i9100g. I bought this set from india and am running the latest stock rom in the same. The problem is something like this:
1. When ever i click some pics in the area with very less light in the area but not completely dark, the pictures I take come out very dark (even when i switch on the flash). If i click pictures from normal i9100 from the same position , the pictures come out very proper and are not dark at all. I last updated the camera fix which the samsung guys pushed out for our phone. Nothing apart from that .... I tried multiple camera softwares but the picture always comes out dark. Technically speaking, i feel that the picture is getting captured with some delays from the time when the flash works .... but not so sure ...... can some one guide as to what can i do about the issue ....
2. One more weird thing i am facing is something like this..... I like to hear music on my phone and purchased a set of Dual driver headphones (no mic) for using with my phone (Klipsch). But with each and every music player application i use, i am getting very high disturbance noises from the headphones whenever the volume is below 8. As soon as i am increasing the volume above 8 , the disturbances or the noise vanishes. I am not able to understand if it has to do something with the hardware or the software as samsung is known to have [email protected] $hit like softwares..... Please advice ....
My software config is like this :
Baseband Version : I9100GDDKL1
Kernel: 2.6.35.7 [email protected] #2
Build: GINGERBREAD.XWLC2
PDA: I9100GXWLC2
PHONE: I9100GDDKL1
CSC: I9100GODDKL1
1- Root and get superrom v3.1 or Prometheus rom or GalaxyRom 5.1.
2- Root with either lucifr kernel, codeworkx kernel or streetware kernel. They generally fix all music related problems.
Overall, you need custom kernel and custom rom.
Seems like the issue was with the samsung crappy code itself.
Though in ICS they have fixed it. The music is not scratchy at all and the pictures now seem like the proper shade and not dark.
Download the ICS update, haven't encountered any music skipping.

Screen flashes red before locking?

I press lock and the screen flashes red then turns off. Hasn't happend on my previous S3 and G3. Is this a problem or should I not be worried? I can provide video if needed. The phone still works and is all completely fine it's just this.
MIUI Version 8.0.12.0. Chinese Stable ROM. I've had other people tell me this hasn't happened to them so I'm confused :\
I was on a vendor rom and I certainly didn't seem to notice it then but I might have still been happening. Could it be a software issue?

Red screen
Hello. I have Xiaomi mi 5s plus and the same thing is happening to me, when I turn off the screen, it flashes red just before locking.
Have you been able to find the source of the issue, is the phone still working
I've just noticed that my Mi MIX also flashes red before turning off the screen. Having said that, I haven't noticed any abnormalities that affects the phone yet. It seems like it's just a colouring issue before turning off the screen. No biggie.
Can anyone enlighten me on this matter? Thanks
In my opinion it's just a part of weird turning off animation which is brought recently. I realised that recently, yet not that serious observation like you did lol. I guess nothing to worry about.
Mi MIX
7.4.14 Épic
Stopped happening when I used the Resurrection Remix ROM for the Mix, so I guess it's just a MIUI issue, not a hardware issue.
Yup, I can confirmed that it's a MIUI bug. Just flashed the Resurrection Remix Rom, and the red flashing thing has stopped.
Normal in MIUI. Crist, what a detail that you observed, haha
I have Xiaomi Mi Note 3 and the same thing is happening to me. I have been suspicious of tempered glass or hardware. I was wrong.
Miui Version: 9 I 7.12.21
PS: I installed Resurrection Remix ROM but screen still flashed red before locking.
Check developer settings are turned off!

Found A Bug With YouTube HDR w/ Autobrightness? (Oreo April Patch)

So I was appreciating the beautiful display on the Note 8 and it's abilities again today by watching a HDR video from YouTube on it, but I noticed something weird. Whenever I went from a bright to a dark environment, (lit bedroom to dark living room) the screen would drop to a lower brightness, then realize it's in HDR mode and go all the way back up, and it would alternate multiple times as I moved around in the dark environment. It would drop to a low brightness, pick back up to full, drop, repeat. Can anyone else test to see if this is happening with theirs too?
Settings: WQHD+ resolution, Auto Brightness enabled, Video Enhancer enabled
Video:https://youtu.be/tO01J-M3g0U
This will help me confirm whether it is indeed a software bug introduced in Oreo/April Patch or if it's my own hardware that's having issues. Thanks for the help!
I would say it is a software bug.
This was happening to me after the Oreo update, unsure what I done that resolved it though but, after flashing a custom rom and going back to stock it has worked fine for me. Using the same Oreo package that I used to update to Oreo the first time also.
I am really sad to hear about all these bugs due to OREO updating, they make me think that it has far more cons than pros over nougat, in my country no Oreo ota yet, I will stay this way until a really good oreo comes out...

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.
Are you facing any other issues else?

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.

If u used Oreo before u upgraded pie u would saw the difference
I can't connect phone to my PC after update, i get 'USB Device Not Recognized' notification when I try to connect. Anybody else has this issue?

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).

Question What to know before installing LineageOS

Hello!
The LineageOS thread is getting very long at 12 pages now, I am looking to install it, but since this thread is so long, it is hard to track what is fixed and what is an issue. So please, if some of you with Lineage could reply with some of the current issues it would be very helpful for me and other people.
I will try my best to add them to a list below for other people looking to install Lineage This is what I have gathered so far.
No vibrations after screen/SIM unlock
Fingerprint scanner only works with screen on
Fingerprint scanner flashes the entire display at max brightness
Night light does not work
(Maybe) No data roaming
(Maybe) Bluetooth APTX codec does not work for calls
(Not a bug) Screen refresh rate can only be changed with adb
Quick update: I installed Lineage anyway lol. For me all haptic feedback works, so I barrwd it from the list. Some I could not test. Overall Lineage is sooo much smoother than the stock ROM, Asus removed so many little animations. Also I noticed the sometimes, screen kind of shifts colors rapidly, maybe this is related to auto brightness...
Edit2: its not the auto brightness so my next hypothesis is the refresh rate going to 60 and back to 120 when I touch the screen
Edit3: it seems to be switching between 120/60 to 90 for some reason? I tried manually switching refresh rates with adb and saw a very small difference between 60/120, but with 90Hz, the colors are all over the place, same happened on the stock rom too.
