I've tried everything on my Sprint variant S8 and the edge lighting notification will not work when the screen is off. Yes I have all notifications set to yes with edge lighting set to When Screen Is Off and I even reset my phone entirely with no luck. All I get when I receive a text is the notification sound with the flashing LED. I also tried Screen Always On and still no edge lighting. Is anyone else having this problem? Also, the lock screen doesn't come on for a few seconds showing the notification say like it would on the iPhone. Anyone with the same issues or resolutions please help !?!?
