How to Fully Erase Everything on a Android Phone

 

Completely wipe your Android device

 

Step one: Encrypting

 To encrypt your device on stock Android, enter settings, click on Security, and select Encrypt phone. The feature may be located under different options on other devices.

 

Step two: Perform a factory reset

The next thing you will want to do is perform a factory reset. This can be done on stock Android by selecting Factory data reset in the Backup & reset option in the settings menu. You should be aware that this will erase all of the data on your phone and that you should backup anything you don't want to lose.
