I'm on 31.1004.0404.68. Ever since it was upgraded to android 12, I'm having serious problems with proximity sensor.
On many occasions, during calls, the screen keeps accepting touches, with undesirable behaviour - camera turns on, WiFi turns off, etc. This has got to do with the proximity sensor not sensing my ear against the screen.
Also sometimes the light sensor seems to have wrong readings and, despite having brightness to about 80%, the screen is completely unreadable.
How can I fix this?
