Camera problem
I bought an iPhone 13 Pro Max 256GB a few weeks ago. Carefully used, do not throw away. Yesterday I noticed a very strange thing with the camera, when a slightly zoomed-in picture is taken in the light, stripes appear on the sides (see in the picture), but this defect is only for whatsapp, not with a normal camera. I have restarted the phone but it helps for a couple of times, what could this be the problem?
iPhone 13 Pro Max, iOS 15
