You might have fun impressing your friends by answering your phone or switching music tracks with a wave of your hand. But your GS4 is wasting energy just waiting for you to pretend you’re a wizard.

If you want to turn off just Air Gestures, you can do that from within the Quick Settings menu by swiping down from the top of the screen and then tapping the Air Gesture icon.
