The only reason I used Samsung's awful messaging app was because it could do a small bubble showing me my texts without waking the rest of the screen. it also does this small bubble message popup when we get a text with screen on. this makes it very good at not obstructing what you're looking at. it also has a cool edge light effect when you get a message, but just the no waking the rest of the screen feature when display is off, would be fantastic!
