Solved In My Left Side Of The Screen I Have Some Pixels Are Dont Work Perfect Galaxy S7 Edge

Chosen Solution

The screen didn’t get any hit

Try taking the phone apart, before you undo the crews turn the phone off (THIS IS IMPORTANT, I LEARNED THE HARD WAY) before you rip the screen off there should be some ribbon cables, mark where they are and use a flathead screwdriver to pop them off (BE CAREFUL!!!!!!!!!!!!!!) then use a clean brush and clean both the phone connection points and the connectors on the cables replace the screen and turn it on, if the problem persists try buying a new screen from ifixit
