Android Question Deinstallation: How to remove data files

If you create files in DirDefaultExternal when the user uninstalls the app all that data will be gone.

Hmm ... This seems logical, and on my Motorola Moto G it works like that. My tester has an LG, Android version 4.1.2, the data remains. He is very reliable and ready to show it to me in person.

His app also freezes sometimes when trying to find the location with GPS. Mine works fine.

Some problems simply cannot be solved
