iphone XR screen shadow
My iphone XR has developed a shadow on the screen, in the top left corner it is grey, the middle of the screen looks like a giraffe pattern (seriously the only way i can describe it) and there is a bright line at the very bottom of the display. I've rebooted it a couple of times, all updates have been completed. It hasn't been dropped, it isn't in the camera its definitely the screen. Help please !!!!
iPhone XR, iOS 15
