Just go to your messanger apps specifically. (Like whats app or telegram or Gmail or ...) . Go to "setting" on each app. Then go to notification. After that turn on "pop up notification"... now it's gonna work whether ur screen is on or off . @Purple Peanut wrote: I have been playing around with my note 9 settings for a couple of days now, and I still can't seem to get the edge lighting to work properly when the screen is off (locked), even though the "Always On Display" is on. At first it worked, then for some reason it just stopped. And no matter how many different settings I tried, it couldn't get it to work again. So far, the only workaround that could help it work is if I set the pop-up notification to on. If the pop-up notif is on, the edge lighting work. But it is REALLY ANNOYING that every time I pressed the home button, instead of the home screen / lock screen, I am greeted by the pop-up, and I have to close it first to get to the lock screen. I read that this has been a common problem for S8 and S9 users, but I haven't found any thread for Note 9, although I'm fairly certain mine can't be the only one. IS THERE ANY WAY TO GET IT TO WORK WITHOUT HAVING TO TURN ON POP-UP NOTIFICATION??? This has been a common problem for quite a while now, I don't understand why Samsung doesn't even try to fix the problem?
