I am currently using Galaxy S9 Plus on Verizon and with Apex launcher. From the last week, when I get a text message or a new message in Facebook Messenger I don't just get a notification in the bar at the top, but an actual pop-up that comes up over the top of anything else and goes all the way across the top of the screen and about three quarters of an inch tall. It stays up for four or five seconds before going away. As you can see this is pretty annoying and I have tried to control it but I can find no setting regarding this matter. It does not seem to be app specific as it comes up with texts, voice mail notifications, Facebook messenger message notifications and maybe others. Does anyone know how to get rid of these and have just the normal notifications?
