is it possible to restore back to an earlier date on my samsung tablet 2? My app crashed. So I uninstalled and reinstalled it thinking that the progress would still be saved on the game, but it wasn't. Is there a way of going back to an earlier date like you can do on a normal PC?
You mean like a Windows Restore Point that is created automatically? Android doesn't have this feature. What is normally done for Android devices is to create a manual backup that can be done using nandroid or a third-party application like Titanium Backup. Then, you restore those back-ups.
