So I was one of the people who got the 4.1.2 Jelly Bean update on christmas eve. Well ever since then my phone has been dying rather fast a lost faster then it use to and it's became slow! It's not fast like it use to be. I loved my phone until I got this unfinished Jelly Bean software, sometimes it takes 30 seconds or longer for the system menu to come up for instance i was on the home screen i pushed the menu button to go in the sounds menu I literly waited 36 seconds for the main menu screen to pop up so I could even click on the sounds option. Also on the Ice Cream Sandwhich there was a power option called Sleep mode that I used every night well it's no longer there now. This Update has completely made me hate my phone and I use to love it. I've called tech support and also went into the store and all I'm told is SORRY YOU"LL JUST HAVE TO WAIT FOR THE OFFICIAL RELEASE TO COME OUT AND THEN "MAYBE" IT WILL CORRECT THE PROBLEMS! Mean while I'm just suppose to deal with it and carry a charger with me every where I go cuz my battery is dead with in 2 hours and that's with me listening to music and checking my facebook a couple of times.
