Iphone 6 screen selectively responsive
Yesterday at about 2 pm my screen just stopped responding, it randomly starts functioning for a few seconds, then goes back to not working. I don't think I dropped it because it was working all day yesterday. I've soft reset, hard reset, done a DFU restore, nothing has worked. I don't think I have the "disease" because there's not grey bar at the top of the screen, the whole screen looks completely fine. Any ideas as to how to fix this?
iPhone 6, iOS 12.0.1
