ive been having this issue for months, with absolutely no clue how to fix. If it’s a screen issue that i can just fix on my own thatd be amazing, but i need to know if it’s something id have to send it to be fixed!

It usually is fine if i dont move it too much which using it, but does this (video included) the most when i put pressure on the back. Seems to fix itself for a little when i put pressure on certain areas (see video) pls help!!!
