Ever since the update more than a week ago... * Battery life is atrocious. * GPS not working properly on some software * Tethering not keeping active I figure I could do a factory reset and go back to the version of Jellybean that came initially with the phone when it was released a year ago...correct? I have an app that will back everything up so I am not too concerned about having to restore my entire apps/widgets upon reverting. I just want to make certain that I can go back to Jellybean. Of course, I probably won't be able to get the Jellybean updates that came prior to KitKat.
