I have an iphone 6se and it got ran over by a car a few months ago and my dad had the cracked screen repaired. Since then the phone has been acting all glitchy and the keyboard goes all over the place or wont type and sometimes pressing things is also all over the place. My dad took the phone back to get fixed again and I used another phone for a few months and I started using it again recently (I think my dad was kind of using it a bit during the time I wasn’t). After a couple of days the same problems started again and it takes forever to type even a simple message. I keep on clicking the screen to turn off and n again to try to be able to correctly type the message and its getting really frustrating. Is there a way to fix these problems?
Now that you have had two replacement screens and the same symptoms occur, I suspect the issue is with the logic board…the phone was crushed by a car after all. This will require that it be looked at by a repair shop that does micro-soldering repairs. It could be as simple as a damaged connector or it could be some damaged IC’s or solder balls.
