There seems to be more than one problem with the iPhone 6 camera. Tom’s Guide ran a piece about purple tinges and possible chromatic aberration, though that appears to be software related as it happens on the iPhone 5S with iOS 8, as well. We’ve seen a few reports of people starting up the camera app on the iPhone 6 and 6 Plus only to find a black screen. We’ve also seen reports of photographs being rotated to the wrong orientation. [Note: There have been fewer reports of this issue since the release of iOS 9 and its successive updates.]
- Try going to Settings > General > Reset > Reset All Settings and see if that makes a difference. You will need to set up some bits and pieces again after, but it won’t delete any files or photos.
- Some owners found it was caused by an old backup. If you are restoring from a backup you made with an older iPhone, that could be the problem. Try setting the iPhone 6 up as new, factory reset it, and then put everything on it manually, and you might find that the problem is gone.
- If it persists, then you may have a hardware fault and you should contact Apple or head into an Apple Store to get it looked at. They should replace it for free if there’s a problem.
