The Air Gesture feature on the Galaxy devices lets you view your new notifications without unlocking your device. But what about LG phones? To view notification in LG G4 without unlocking the screen, you just need to swipe down from the top of the screen, as if you are going to expand the notification bar, just about halfway down and there you are. You get to see the new notifications as well as the time and date, while the screen is off and your G4 is locked
** Note that, as far as we tested, there must be a locking method applied to view notifications in LG G4 without unlocking the screen.
