gray spot on the top left corner of my screen
why there is a gray spot on top left of my screen? the gray spot is clearly to see in every color except white. is it harmful to my phone?
Yes, it could lead to a bigger problem with the screen in the future. I suggest you contact apple support and take it to them for a check up. Make sure you book an appointment before you go. Is your phone under warranty?
