The latest update crashes my system. It keeps saying UI is not responding  especially when I hold down the main button to get to the taskbar. I have to revert this to factory version just so I could use my galaxy 10.1 tab. This is insane. Please fix it asap since it's the core of the android system. It's not just me  and this is not a tantrum. I've seen this same problem pop up in tech forums everywhere. Again  please fix it. Asap. Thanks.
