Before updating any smartphone is always a good idea to backup all of your data. We also recommend that you read what the update does, it sometimes changes the homescreens and settings such as taking a screenshot which can be confusing. Sometimes updates ad glitches while fixing others.
New features of Android 4.1 Jelly Bean include voice actions, expanded notifications, larger Android Beam files, resizable widgets, tablets look more like Android smartphones and a better keyboard.
The updates are also cutting out some features due to the massive amount of patent infringement lawsuits between all the smart phone makers. The unified search feature is removed in these updates.
Jelly Bean features improved performance throughout the system, including faster orientation changes, faster responses when switching between recent apps, and smoother and more consistent rendering across the system through vsync and triple buffering.
