Jelly bean and ice cream sandwich are two of the Android versions that have become available over the years. Ice cream sandwich is known as the older version of Android between the two as it is Android 4.0 while the jelly bean is Android 4.1. A lot of people noticed when they updated before that Jelly Bean is faster and smoother.
There were a few differences with the interface of the two but those who are not too aware of the changes did not notice. One of the most obvious differences between the two is the speed. There is no doubt that the jelly bean worked faster than the ice cream sandwich.
