I recently went JB 4.1 and I have a lot of unexplained lagging on my phone. One of the apps that has started running constantly in the background is the Google Play Music App. It never did this prior to the update. I can force stop it but with in a few minutes it has restarted, is this normal? Is this why my phone seems to lag, severely at times, for no reason that I can see? I'm pretty new to Android and extremely new to JB and my Note and I'm starting to get concerned about the ongoing issues I'm having now. Any thoughts would be wonderful
