I am from PL, fresh iphone XR, white 13.1.3 - HDR on - stripes at photos with contrast colors, but even in the normal daylight...
More precissely It happens when u for example have a bright light (window) at the area of the photo but u are focusing on something dark and vualla u have stripes... I had read all available topics and...:
- most people say that they never had this effect on IOS 12 ... it appeared when updated to IOS 13
- it only happens when HDR is on - I agree
- it happens on different models too for example iphone xs/6s max
- 2-3 people said that they went to apple store and had new camera module exchange and problem was gone, but one of them found then different problem (stripes, but smaller and different)
- 1 guy said that it could be realted to ESD during the production process - cause is microchip damage - it is an option...
- couple of people said that it is related to LED light? It sounds very logic but i must say no, as I said in the daylight problem is still existing.
Soo summerizing, these troubleshotings are soo much different from each other, basing on them i still have no clue if i must go to apple store.. It drains my time, i don't want to. Hope it is software issue. Today my sister will come with here Xr and 13.1.3 then we'll see.
What apple is doing about that? Only thing that i could read they have no idea (genius'es) yeah restore ur software etc... wasting time. Maybe check if ur phone is 100% charged? :D ha ha
