Deleting Android data securely - how to do it

As soon as you buy a new smartphone, it makes sense to sell or give away the old one. In some circumstances, your data can still be read even after the smartphone is cleaned up. To prevent this from happening, there is a way to securely delete the data from your phone.

How to delete your Android smartphone data

When you reset your Android smartphone to factory settings, your data is only conditionally deleted. Generally, in the file system of the phone, the basic path is set to 0 or NULL. However, the data of the Internet memory is still present to some extent. It is just no longer referenced. To remove the data, you should use an external program.

1. First create a backup of your data. So you still have them available later.
2. Now log off all accounts of the device. To do this, go to the "Settings" > "Users" > "Accounts". In the overview, now select each account individually and then tap on "Remove account" via the three small dots.
3. Reset the phone to factory settings.
4. Now use the free program OW Shredder to delete all data properly. Connect the phone to the PC and launch Shredder.
5. Select the smartphone's memory and clean it up. Danach setzen Sie das Telefon erneut auf Werkseinstellungen zurück.
