A factory reset is the most commonly used method to wipe a phone clean. However, the technique only deletes the data addresses thus hiding the location. Unlike Android Eraser, using the factory reset does not overwrite the data and files in the smart device. It means that the files can be recovered using off-the-shelf recovery software, such as Coolmuster Lab.Fone for Android.
However, you can still remove all data from your Android phone by following the following steps:
Step 1. Tap the "Settings" icon on your Android phone.
Step 2. Select "Backup & reset" and then "Factory data reset".
Step 3. Confirm your choice by tapping on the "Reset phone" option.
