Has anyone had any experience taking an iPhone 5S to an Apple Store to replace the rear camera? If so, were they able to do it, and how much did it cost you? My camera lens has some pits and cracks or something that creates some artifacts on every picture (they almost look like sensor dust). I'm replacing it with a 6s Plus (which literally just arrived as I type this) but I'm handing my 5S down to my 8 yr old to use as an iPod and if it's not too expensive to fix the camera I think I'll consider it. Honestly though I doubt she'd notice.
