There is a vertical green line going up my screen. I was told that this is a defect but since my screen has a minor crack, I would have to pay to "repair" (there is no repair for an iPhone XS screen. You can only replace it) the screen before they could fix the defect. I happen to know that there is no fix to this defect except for replacing the screen or replacing the phone. This does not feel right since it is a defect. Does anyone have insight?
