I just bought iphone 12. when i setting up everything in night time with dark mode on. I have noticed pueple haze on setting, insta chats in the dark mode.
Its with all iphone 12 devices.
If u have Iphone check it with below setting.
Make sure FULL OR HALF BRIGHTNESS WITH DARKMODE IN NIGHT TIME. Then go to setting swipe up or down or left or right. U will notice in between black and grey meeting point of screen.
