I’ve had my FP2 for 4 1/2 years now without any real hardware problems. All components are still the original ones except for the case - not so bad!
About half a year ago I noticed that the left side of my screen does not react to touch any more. It effectively prevents me from pressing the “q” on the qwerty keyboard - but I can live with that.
Last week another problem appeared: Ghost touches. My screen went completely wild and made the phone unusable. I disassembled the phone and cleaned all screen contacts with alcohol. It worked again after that - up to today. Out of nowhere the same problem appeared again while I was using my phone. I disassembled it and put it back together. This did not help. So I cleaned the contacts once more. That helped - for now.
I’m willing to buy a new screen if that is truly the problem. But before wasting money on that I’d like to know if anyone knows of a non-screen related problem that could cause this. I’m currently ruling out software issues based on my experience with the phone so far and the fact that cleaning the contacts seems to help.
Any hints about what I could still check are welcome!
