I have this weirdly perfect long purple oval on my screen thats only mostly visible when on whiter screens. This was never here before and only showed up after the latest update. Is anyone else having this issue? My battery never overheated, no damage or anything, only showing up after the new update and its irritating. Anyone else experiencing this? It's not screen burn in either cause i never leave my screen on one thing and nothing that would cause a perfect long oval like this.
