Xiaomi 14.0.20 POCO X3. NFC proximity sensor

[Korgar]

Hello, recently I'm experiencing some proximity sensor bugs I never had before.

My setup is:
- poco x3 nfc
- Xiaomi.eu rom 14.0.2.0
- Magisk 26.1

The calls from the phone app and WhatsApp gave me black screen each time.
Using the Cit menu (dialer *#*#6484#*#* or about info, tap kernel 5 times or more), proximity sensor calibration, it's set to 0, I tap calibrate and it says 5, seems to work.
But if I lockscreen the phone and unlock it then it returns to 0.

The previous rom didn't have this issue. Is anyone else facing the same?

I fixed it by cleaning the upper part, the dirt covered the sensor and now it works as it expected.

Case closed.
