I just got this iphone from ebay, it has quite a bit of cracks... But like, when i put "sun glare" on the iphone, its like i can see behind the gray bar. its just a bit bigger then half of the dock. ive tried restoreing and stuff. I dont know why is this, if i can see behind the gray bar with glare on the screen, what is this gray bar? And can i fix it?
This is the picture from ebay, ill take a recent picture soon. but im just worried about the gray bar.
