purple tinting on the edges. Speculation is that this is the result of the Sapphire glass used on the camera's lens. Another thought is that the problem comes from the light sensor on the camera getting overloaded. While the camera on the Apple iPhone 5 can compensate in some situations, in others the purple tint takes over the picture.
Since word of this purple picture problem started making its way around the interwebs, some have taken to their Twitter account to tweet that the same problem exists on the Apple iPhone 4S. Those who have tested this say that it is true that last year's iPhone model does produce the tint on some pictures, but it is much more apparent on the newer version of Apple's smartphone.
So far, no word from Apple on the latest issue facing Apple iPhone 5 users.
