iPhone 6 plus screen does not Swipe properly

Okay so this issue seems to be pretty unique because i looked through all the questions here and I did not find anything but I work in a Phone repair place and I encounter this pretty often.

Iphone 6 lightly bent frame on the top right corner. The screen does not swipe sometimes. There are small thick lines only on the top of the screen (flickering). Once i put pressure on the frame on the top right corner screen seems to start work again when I let go this flickering starts again and screen has issues again.

I would really appreciate if someone can give me an answer on that!

*checked multiple screens, sure it is not long screw issue (no screws installed), encounter this on multiple phones, Apple used to replace those but nowadays the manufactured warranty is expired!

• Thank You!
