iPhone 7 Plus camera extreme flare
Randomly, the camera on my iPhone 7+ (running iOS 10.2) starting being really weird. There is a HUGE flare whenever there is a light source in the camera shot.
To demonstrate:
My kitchen lights taken on my mum's iPhone 5C:
Same shot taken on my phone:
Tried resetting but it didn't do anything. As far as I can see the lens is not scratched but it may just be too fine for me to see it. But I noticed if I tap the lens the flare changes direction??? like from vertical to horizontal, it's really weird.
Any ideas what could be causing this bizarre issue and how to solve it??
