Android 4.1 Jelly Bean: What Changed

Android Jelly Bean brought a lot of new feature and enhancements to already popular android ice cream sandwich. Jelly bean makes the whole UI very fluid removing some lagginess that existed even with ice cream sandwich. Thanks to Project Butter for this. Besides Project Butter, Google now was also introduced with jelly bean which gives voice feedback to users question and requests. Google now also shows relevant notification based on users preferences if the user opts to use it. Overall the UI did not change much. Some changes are seen in the google search widget, lockscreen and camera app.
