Hey, i also experience really random Touchscreen issues.
Because it happens so randomly i really think its just a Software related Problem.
I had the crazy ghosting touch for a few times.
I also sometimes see pretty big squarelike artefacts on the bottom of the screen when scrolling down, also scrolling seems to be hindered by that bug. I see that pretty often.
i also experience frozen srceens in some situations, i can mostly resolve that with shutting the screen and turning it back in.
And i have another bug i would open a New topic for. Its random reboots when im surfing the web, downloading,...
Just wanted to say, im still very happy with the phone, looking forward to some bug fixes by Fairphone.
I really think its all just minor Software bugs.
And i wonder if any kind of crash report system would help support to identify software problems?
