I don't want my files (photos and videos) to be restored from my Samsung Galaxy Young mobile. I didn't have an SD card, and I don't want my deleted files to be restored. How can I get some assurance of this thing?
Unfortunately, there is no application that you can run on your Android device in order to make your data unrecoverable. However, you can try to use a manager for the device and remove the photos, videos from your phone using a tool like XL Delete or Eraser. This is the only way to make sure that no one will be able to recover your media files.
