I've got a Google Pixel 8 Pro running GrapheneOS. When I'm on the phone talking to somebody and hold the phone to my ear, it very often accidentally registers taps. This e.g. leads to activation of the flashlight or Bluetooth by the slide-down menu. Locking the screen after answering the call does not help, probably because the slide-down menu is accessible anyway. I cannot find any setting to prevent this. Does anyone have the same issue or any idea of how to fix this?
I used the app Sensors Toolbox to check whether the proximity sensor works as it should. And it does. However, it only detects small distances at the top of the phone (where the ear should be during the call, which is not always the case). If the phone detects a small distance to the skin during the call, the screen is deactivated, but is activated if the phone slips a little from that position. Is this normal?
