Hi! When I charge my recently bought Xperia z2 tablet, it goes back to all initial configurations, I mean, icons on homescreen that I have added, theme, and other personalization disappear so I have to do it all again. I already tried to turn it off before charging but it happened the same way. When I disconnect the cable, after 1 minute, those images presenting the tablet (vivid colors, etc...) appear and then everything's back to initial configuration. Apps I downloaded are still in settings, though. Any chance on help? Thanks!
