Hi all, I have the Galaxy tab 10.1 and recently upon starting the tablet I got the first home-screen as if it was new, but all installed application still installed. Unfortunately no applications work since then. Also I keep getting "the process com.xxxxxxxxx has stopped unexpectedly. Please try again. These apply to applications like google play, skype, tango. It also happens when I try opening any other application. Please help!!! Thank you.
