Small blue squiggly lines on photos taken with iPhone
These blue squiggly lines have appeared when i take photos with my front & rear facing iPhone 6 camera. They have not always been there and there doesn't seem to be any damage to either of the lenses. I know they are small but are easily noticeable especially when zoomed in. How are they caused? is this something apple can fix? i have found no questions similar to this on the web.
iPhone 6, iOS 9.2
