I’m experiencing some ghost inputs to my Fairphone’s touchscreen that make the phone basically unusable. They weren’t present when I originally got the phone, but seem to have developed over time. Basically the screen will suddenly start ignoring inputs, and then begin acting as though I’m touching all over in quick succession, even when my hand is nowhere near the screen. I tried disassembling the phone, cleaning the contacts and re-assembling it, however that’s not changed the situation at all (and I definitely made sure the screws near the contact are seated firmly).
Is there anything I can try to do to resolve this?
