iPhone 6S Dead Pixels (upper left corner of screen)
I got my iPhone 6S a few weeks ago, and after 1 week, I noticed there was a cluster of dead pixels in the upper left corner of the screen. I contacted apple and had the phone replaced, and 1 week after getting my replacement, I noticed, again, a cluster of dead pixels IN THE EXACT SAME SPOT ON THE SCREEN (upper left corner). What could be the cause of this problem?
iPhone 6s, iOS 9.2.1
