"So I was playing with my new phone and all of a sudden, this happened," said one MacRumors forum member with the alias tmiles81. "It's a really bright line going down the entire right side of the phone."
The issue doesn't resolve itself with a reboot or restore; however, the line can apparently move to a different area of the screen. It wasn't present at the time of unboxing and has affected users with different model devices.
