SPB Shell 3D is an Android home screen launcher that transforms your handset’s user interface to make it look a lot fresher and futuristic. The change isn’t just aesthetic, but also opens the gates to multiple possibilities. The app lets you have different screens at the same time, and switch between them seamlessly with just a finger swipe or touch. Another interesting aspect is the smart folder feature, which would let you glance contents, or the widgets you could use for personalizing your phone.
