I haven't used Smart Scroll or Smart Pause for more than a few minutes during a demo at the device launch, but it worked well in my limited tests. You can turn off both features if you'd rather not use them.
Galaxy S4 Air View and Air Gesture
Two more new and unique Galaxy S4 features are Air View and Air Gesture. Samsung's Galaxy Note II device has some gesture-based Air View features, but users need to employ the Note II "S Pen" stylus. The Galaxy S4 Air View features let users swipe their hands across device displays to answer calls, skip audio tracks, navigate through browser pages and photo albums and more much, without the use of a stylus.
