So, all of a sudden I noticed that all my iPhone 5 photos and videos had a sharp purple smear on them. I've got the latest version of iOS 6 and this mark is consistent across all camera apps and different video resolutions. I think it looks like a scratch, it won't move or be rubbed off. What do you guys think? Anything I can do to help with it? I treat this phone well, I've never had any other phone or camera get so much as tiny smudge on the lens. I've looked at the phone lens under a big magnifying glass and can't see any scratches on it.
