Before selling a device, there is always a need to completely clear the storage of personal data. You should not trust the factory reset, because the Internet is full of ways to recover files.

You can use third-party helpers, such as the Extirpater app (https://gitlab.com/divested-mobile/extirpater), which will permanently destroy all data on your Android device. Before use, it is worth remembering that such utilities, with frequent use, destroy the gadget's drive.

The cleaning algorithm is quite simple, but effective: with standard data deletion, files are not destroyed, but only disappear from the file system index. This tool fills the remaining disk space with random noise, and then cleans everything clean.
