Running Android 4.0; installed several games, and after a couple of weeks, the games don't play properly, do strange things, crash. Uninstalled the games, and reinstalled them. The games still play erratically and crash. Other functions and programs work normally. When uninstalling, does some code from the program remain? Windows can do this with it's registry. Is there some way to ensure a complete uninstall of a program ?? Help is appreciated.
