Samsung introduced a slew of new features as part of TouchWiz (based on Android 4.2.2) on the Samsung Galaxy S 4. This guide will discuss Air View and Air Gestures, which are all about using your finger or hand to be more productive. Air View was first seen on the Galaxy Note II, but you needed an S Pen. Now you can hover your finger over emails to read the text without actually opening it, and you can see the pictures in a folder without actually tapping it. You can even use your finger as a magnifying glass in the stock browser.
Air Gestures will let you navigate by just the use of your hand. Instead of swiping your finger from picture to picture in your gallery, you can wave your hand instead. You can even answer your phone without picking it up. You will find quick on/off toggles for both Air View and Air Gestures in your notification pull down, but you might need to fine tune the settings a little. Just hit the break for our video showing you how to set them up and how to use them.
