I guess I have horrible horrible luck because my phone has more problems after the update than I can probably list. To name a few: No status bar, no notification pull down, battery dies quicker and I can't see my battery percentage anyways, cannot change the background of the phone, the volume does not get but about half as loud as it used to and the volume gauge no longer pops up on the screen, my home button no longer works at all, multiple, check that, 75% of apps don't work correctly anymore, and GPS does not work properly at all. I'm sure I have missed a couple of problems too. My phone worked perfectly before the update. I took it to AT&T (my provider obviously) and they said there was nothing they could do that I should call Samsung. After thirty minutes and no answers from Samsung I gave up. Super frustrating
