Hi there!
What happened so far
Bought FP2 - works fine (minor glitches).
Did all the FP2 updates - most glitches vanished.
After about 3month got problems with screen, becoming more severe every week (about one stage per week -> see below).
The problem(s)
- First stage, the screen started flickering sometimes. Mostly in the morning. Stopped after some minutes.
- Second, the screen did not respond to touch anymore. Mostly in the morning. Stopped, after some minutes.
- Third, the screen did random touch-input without anyone touching it. The worst results could be avoided by clicking the on/off button -> to switch the screen off. Stopped after some minutes.
- Fourth the screen was just black and did not turn on at all. Mostly in the morning or after carrrying it around and not using it.
- Finally, I found that 1-4 happened almost every morning OR after starting it OR after carrying the FP2 with me for some while. I also noticed that the results varied depending how I HOLD the phone in my HAND.
If I gently pressed the phone from left and right (the way I usually hold any smartphone in my left hand), all the above might occur.

If I smoothely pulled the back cover from the screen either left or right, the screen immediately went dark.
If I pushed the screen in the middle with a bit of force (I am a rather careful person), everything was good again!

At this time I was quite unhappy with my FP2, I switched back to my old Nexus for daily use and started looking for help in the forum.

Solution
As I stated above, I was able to influence the behaviour of FP2s screen by gently pressing left/right or the middle of the screen or by pulling the cover from the screen a bit left or right.
So I figured it was a hardware problem rather than a software glitch.
I removed the screen part and cleaned it (as stated in “Solutions for FP2 blackscreen issues”).
No result.
I tried it again and cleaned the contacts thoroughly with a soft cloth and a drop of anti static agent (I guess alcohol would do the trick).
It worked!!

Until now
I started using the FP2 again. Now, about one month later the screen starts flickering again. I hope it does not get any worse!!! If so, I will try cleaning it again. Perhaps someone else had similiar experiences and would like to share their solution??
