AODNotify is a decent app but I don't understand why Samsung can't put this feature in ONE UI 5 at the very least put it in good lock. I REALLY don't like using 3rd party apps for something so simple. It literally does it when switching from regular to selfie camera. A white line circles the camera lens on the screen. Let's get it done.
It's too high on the screen in my opinion but other than that yes it is! I think Samsung could implement their own version that would be more fitting & way more customizable! Especially if they put it in GOOD LOCK.
