Samsung has for a while been at the forefront of introducing cutting-edge software-based innovations into its high-end smartphones. The TouchWiz shell the Korean company developed for Android is becoming increasingly comprehensive. Last year's Galaxy SIII introduced things like Smart stay, Pop Up Video and all kinds of tricks taking advantage of motion and proximity sensors. The Galaxy Note 10.1 added the ability to display two apps next to each other, and the Galaxy Note II came with a preview feature that was activated when you hovered the pen right above the screen. All of these innovations have found their way into the Samsung Galaxy S4, it's almost a best-of collection of what Samsung has developed over the past few years with some new additions.
