On my old phone I had an issue with the proximity sensor and front facing camera. This led me to holding my phone backwards to take photos and being unable to hang up phone calls.
I think I put up with this for a year and a half.
I did end up figuring out the issue with the proximity sensor but opening up my phone to reconnect the camera module was too much effort for me.
Naaah it’s fine, it’s either the CPU not making contact or I scratched the MB with a SATA cable. The boot drive is m.2 so it’s not the cable. Cos it’s started happening after I changed the CPU, and while doing that a SATA cable got stuck behind the MB and I pull it out with force instead of unscrewing the MB :) I just can’t be bothered figure it out anymore lol
