Fingerprint sensor dont work when nighlight turned on. - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

Hi Developer.
Greetings.
I am using pixel experience ROM in Xiaomi redmi K20 pro
I've noticed that the fingerprint sensor doesn't work when the night light is turned on.
Kindly fix this bug.
If you compare with MIUI when the night light turned on.
The night light disables when the fingerprint sensor is functioning.
Kindly fix this issue. Using a phone without a nightlight is a pain in the eye.

Proximity sensor problem

Hi!
Since week or few days more i've started to have problem with proximity sensor during calls. After covering the sensor it doenst turn off the screen. After timeout the screen is black, but after uncovering the sensor it doent wake up the screen.
I use the latest Galnet Miui weekly, and in factory test on miui the proximity sensor works perfectly. I dont know what to do to fixed that.
any ideas?

fingerprint while display is off

I noticed that I can unlock the redmi k20 pro while the display is off. if I hit the fingerprint spot, the screen glows green on the corresponding area and it unlocks. (really conviniend)
Is this a 7th gen sensor feature, or do more phones have it? Or is it simply software?
A friends op 6t needs the display to be on for the fingerprint sensor to start checking, so I got curious.
Edit:
I mean under display fingerprints.
On pocof1 fingerprint reader was also always on , on my k20pro it also always on. when i had lineage installed on poco then you had to wake the screen to unlock so i think it software thing to have it always running in background

Yeah, normal capacitive fingerprints should always work while the display is off, I was wondering about under display ones.
Also i saw option to enable like aod but with fingerprint reader that it always shows on locked screen

proximity and light sensor don't work on LOS 16

Hello,
I did install Lineage OS 16 with TWRP 3.3.1 on my z3c and I got an issue with some sensors. I used some testing apps and neither of them received values from the proximity sensor. This goes together with my experience that the display doesn't turn off while calling. Additionally the brightness of the display doesn't change if I turn on automatic brightness. That's why I think the light sensor isn't working either.
Do you know of any patch to make these sensors working? Or if this is not possible is there a best-practice workaround?
Thanks in advance!

Question Proximity sensor issue

Hi all,
I am facing serious issue on my redmi note 10 pro,
Whenever i make a call the proximity sensor ( idk whether it really has one or not) works fine and when i have to hang up the call my screen doesn't turn on . It goes all Black, no response from the buttons or fingerprint sensor ,
i sometimes need to force restart the device.
If anyone could help will be thankful.
I am having the same Problem here.
Try changing always on display theme or try disabling always on display completely. Doing that solved my issue.

Question Proximity Sensor broken

Hello guys, is there a way to disable the proximity sensor or mock it somehow? Some devices also have an option to disable/enable pocket mode.
Using the phone with a bricked proximity sensor is a bummer, because I can't use AOD, tap to wake, or display new notifications. I would be really thankful if someone could help me.
PS: I always use root, so there shouldn't be any restrictions that way. I also tried xposed and the sensor disabler module, but it didn't work on A11 nor A13.
Update: the sensor is probably not fully broken, it works under bright sunlight, but only under bright sunlight.
