I’ve having the same issue. Anybody knows if a patch will fix It ?
I updated my iPhone X to iOS 14 last week, I've noticed slower performance but that I can bear. My problem exists where the screen becomes totally irresponsive to touch, Face ID sensor is working and the buttons, but the screen just refuses to respond to touch, Force Restarting doesn't seem to do the trick here, it just works after a while of irresponsiveness (5 mins - 2 hrs).
I know that this is a problem with the update because I've never experienced this before. And some may respond that the iPhone X has the "Ghost Touching" problem, that's not it because inmediately after updating to ios 14.01 the problem begin. Before, it ran perfectly well. I'd really like a fix to this problem or a very soon patch update to fix this disastrous one.
