Delete private files forever from your Android device
Want to make sure private files that you want to delete from your phone are completely and safely destroyed? Then check out Secure delete.
The app allows you to select any file from your Android device (only images are supported in the free version) and remove all trace of it. This is useful because when you erase a file in the normal way it can often still be recovered.
Secure delete is a useful app, but its user interface is both ugly and cumbersome to use.
