While I hate to revive such an old thread, it seems better than starting a new one. Did you guys bring these phones in to get swapped? I just had my 6 month old phone swapped due to a faulty home button and my new phone has this issue with the camera. I'm not sure if it's something that will require the device to be switched because it only appears in rather low lighting. I'll need to take some test shots to see how they look. If it doesn't appear in my photos under normal use, I'll just let it be.
