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.
Years ago I got a second hand Sega Saturn - it was fine for a while then stopped working because it couldn’t read the disks.
But then I discovered (not sure how) that if I turned it upside down it would work fine. So I did that for a couple of years.
