For those who've graduated from Easy Mode, Jelly Bean now supports far more variety of the size, shape and behavior of widgets, giving developers more flexibility as to the placement, look and feel of these windows and allowing them to increase functionality. Perhaps most significant are the Lockscreen Widgets, which draw attention to an app every time a device is turned on. As many as five widgets can now be launched from the lock screen to answer a text, skip a song or take a picture.
Samsung's Galaxy S4 also comes with a new version of TouchWiz, which simplifies navigation, adds thousands of functions and features to Android and builds concise help screens right in.
The Galaxy S4 is Samsung's best smartphone yet, and it continues to pull away from iPhone in terms of innovation and productivity features.
