Hi All, I have a zeepad 7 running android 4.2.2 jellybean, and I'm having major issues with it. It is running slow and won't connect to facebook in apps that need it. It shuts down games, says some apps have stopped working all the time and shutdowns apps as they load. I was wondering if anyone knows how to fix these issues? Do I need to update the tablet and how do I do it?
