Hi, My galaxy had a total meltdown and lost all the app data... I have had a lot of issues with it, it reboots alot and I have to remove apps from the sd card and eventually it works...for a little while. So the last time it just totally crashed and re-booted to factory default...i lost all my in app data game saves, etc. Is there a way to back this data up? Do i need to root the phone...? Help!
