Fairphone

Hi all! I have a Fairphone 4 that is serving me very well, but it occasionally reacts as if someone had touched the screen, such as scrolling randomly, zooming in in the camera, pulling down the settings menu, etc. I assume that there's something on the display that occasionally activates something.

I have cleaned the display several times, but still have the issue. Before I buy a new display to swap it out, which costs 70€, I'd like to know if anyone else has had this issue, and if you found a good way to fix it other than swapping out the display :).

Thank you!
