The
Samsung Galaxy S4 is the first phone to launch with Android 4.2.2 Jelly
Bean, the latest version of the OS. However, you would be hard pressed
to see any of the stock UI elements here. Instead of the dark, neon-lit
interiors of stock Android, TouchWiz goes for a bright, vibrant and
peppy (to the point of cartoonish at times) outlook. However, don’t
think it’s all just a reimagining of the stock UI. There are some nifty
additions to the interface, which Samsung claims will improve the
overall user experience
