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.
for 5 years my PC would only turn on at a 45degree angle. It would work fine while upright or sideways after turning it on, but to initially start it up it needed to be tilted. I tried reseating everything many many times, I had even replaced a pretty large number of components over that time. Then I moved and when I plopped down the PC a screw popped out of the PSU. problem solved, and I’m very glad it didn’t explode.
