Tablet froze while playing angry birds then after turning it back on i got some error inscription screen (tablet also just had rebooted randomly before this when playing) When it restarted none of the apps or things i had saved were there and it was all back to factory reset; the 4g card says it only has 1.3g available which is weird.. can't remember if it was this way before it happened?.. anything i can do? the only thing that bothers me is the space in the SD card, is it possible that my old data still there hogging space? and i guess no more angry birds on this... Thank you.
