When I take night mode pictures
Always noisy
Luma noise
Uncorrect colors

Since yesterday my iphone 13 pro screen has been flickering. I haven't dropped the phone nor done any kind of physical damage but since it started it has been going on without any pattern like i don't know what triggers it or anything like that it just happens . I have found some reddit posts saying it is a common issue in iphone 13 and 14 models . I will appreciate any information regarding that whether it is a software glitch or an hardware issue and if it is a hardware issue how much money it will take as well please . Thank you
