When you delete a file, the Android system doesn't actually delete it directly from storage. The system will disguise as if the file no longer exists and the free space increases. Even though the system can still continue to write files to your storage, at least until the file is overwritten by a new file.
This allows you or someone else to recover deleted files, although there are some conditions that must be met. But if you're not careful, someone else can recover your secret files. Even when you've deleted all those files. Obviously this is a serious problem when you want to sell a smartphone. Then, how do we ensure that the files that we have deleted are completely deleted and cannot be restored?

Deleted Files on Smartphones Can Be Restored, Here's How To Solve It
To solve this problem, developerGiuseppe Romano create an android app called Secure Eraser. The app works by overwriting free space on storage after you delete a file, making sure the files you delete are actually deleted forever so that no one can recover the data.
1. Install Secure Eraser

After you install and open it, the first step you have to do is choose whether you want to delete files that have been deleted from internal storage or from external storage. On the right, you select Random to get the best results.
3. Delete Files Forever
Next, you just press the button Start at the bottom of the screen to start deleting files forever. From here, Secure Eraser will overwrite any free space with random data to get rid of files deleted by you. As a result, the available storage space is actually revealed. But, don't worry Secure Eraser will erase this random data and you will get free space back.
This process may take quite a while, it took about thirty minutes to clear 15 GB of free space in the tests that ApkVenue did this time. Of course, the total time will vary depending on the amount of space available on your device. So, wait patiently during the cleaning process. Most importantly the results are satisfactory. You don't have to worry anymore, your important data will completely disappear. What do you think, are you interested in trying it?
