Hi, does anyone know how to tell if a phone screen has been replaced? Its really hard to tell looking at it. The colors are very close. I have a original s21 ultra and just bought another one. So I am basically comparing side by side. My old s21 ultra has some screen burn and the new one doesn't. The one with screen burn seems as if the colors are a tiny bit darker. Is that the screen burn causing the colors to be slightly off?
