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.
Home self hosted stuff is definitely the only time I usually get to have fun with this stuff. Work can sometimes involve fun problem solving but by the time you cut through all the red tape to get it anywhere the thrill is gone.
