Lock screen briefly inverts colors?
I just updated my iPhone 6s to iOS 13.3.1 and I've noticed that every time I go to the lock screen (checking time, notification just came in, etc) the colors are inverted for about a second, before they go back to normal. I checked my settings and inverted colors is off (both classic and smart), yet it still does this. Everything else has normal colors, including the home screen. It's only when I wake the screen that it does this.
