I received the Jelly Bean update last night and installed it this morning. Loving the Google Now feature but I've noticed that there is now a bit of lag on the phone while swiping from one screen to another or when coming out of an app back to the home screen. Example: I sent a text and once sent, hit the home button. It took longer than normal with a bit of a hang-up to go back to the homescreen and then noticed that the homescreen was blank for a second or two? The only thing I have running on my home screen is the Circle Widget. Is there anything that I can do to get the phone back up to the speed that it was prior to the update? I've only had the phone about 10 days and have been loving it, but upgraded to this phone to get rid of the lag that I had on my original Galaxy. Note: My phone is 100% stock and I did turn it off and back on hoping that would correct the problem.
