I dropped my iphone x in a light drop as well. i picked it up and the phone looked fine. no cracked screen or anything wrong with the display, but 1/3 of the screen on the top part is not responding to touch, and it becomes responsive at the bottom of the screen. Is it possible for only a wire or something to be misplaced because the screen looks completely fine and the rest of the touch screen that works works perfectly.
You’r digitizer that needs to be replaced.
