When im watching a video such as in the music app and double tap to zoom in full screen theres a purple fade that appears in the transition. There are also purple lines being left on the screen when scrolling through settings in dark mode. I have just reset the phone to factory settings and the problem is still occurring.
iPhone 12 Pro, iOS 14
This is due to the OLED display. The pure dark background reflects pixels being turned off, when you scroll to areas brighter than pure black those pixels turn back on but due to the speed limitations of the OLED display, pixels simply can’t turn on fast enough causing those purple lines.
In other words, this is totally fine and it’s not an iOS problem, simply the display’s limitation. Hope that helps!
What device do you have? On iphone 12 its so visible that i keep my phone brightness above 50% ,true tone and night shift always off, and its still noticeble!
I did try this as well, to make sure that this is not only happening on my phone, and all iPhone 12 model displays has it.
