ConclusionHence we can see that android 4.1: jellybean OS is the best android OS ever made. But it is not

much different than android 4.0: Ice-cream sandwich. Google have made it more advanced to compete with IOS and windows phone OS. They have shown true capability of android OS.

 We can draw out the following conclusions:pros Silky-smooth performance Improved notifications Chrome as default browser Resizable widgetscons Google Now is limited Available on few devices Few tablet-friendly apps No built-in lost device security

But the main challenge of jellybean is that it won’t be used to with or it won’t be compatible in much hardware and software also will be hard to develop since even ICS is having same problem.
