Part 2 - How to Wipe Android Device by Factory Reset

This is the most commonly used method of wiping a smartphone clean. However, the technique only deletes the data addresses thus hiding the location. Unlike the Coolmuster Android Eraser, using the factory reset does not overwrite the data and files in the tablet or 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 clean the tool properly by following the following steps:

-> Encrypting the data-this is like locking your phone content, and you will have to enter a PIN or a password every time you are turning the device on. For data to be recovered the unique combination will be required to decrypt the gadget and any other individual will not have it.
-> Charge your appliance fully while the procedure is running. Alternatively, you can keep it plugged into the charger to make sure that it does not turn off.
-> Tap on the Settings icon.
-> Scroll down to "Security" and select the "Encrypt phone" option. Nevertheless, this step varies from one gadget to the other. Other models such as Samsung provide the option of encrypting even the SD card.

Completing this process deletes all the data and protects it from decrypting. However, if you want to be entirely sure that all the data cannot be accessed by a third party later, you should consider overwriting the encrypted data with junk data, and then factory reset it again.

Using the Coolmuster Android Eraser and performing a factory reset are the two popular methods of wiping an Android appliance before selling or giving it away.
