ghost touchscreen inputs due to water
I got some water into my phone and the screen has been wonky since then. Sometimes it behaves like normal, but most of the times it does this thing where random touch inputs occur in a column in the middle of the screen.
Edit: It seems like the orientation of the phone has something to do with the touch inputs. When I leave it screen down for a period of time it's fine, but if I turn it screen up, after a while the random inputs start occurring again.
