Part 4. Traditional way to Encrypt and Wipe data from Your Android Phone

In addition to using professional tools to securely erase Android data, there is a primitive way to help protect all your personal data before performing a factory reset on your Android phone. Please follow the steps described below:

Step 1: Encrypt your Android phone

It is recommended that you encrypt your device before preparing to wipe it. That means encrypting the data on your phone. The purpose of this is equivalent to perform a double protection on your phone. After that, even if the factory reset cannot completely delete the data, if others want to steal your mobile phone data, they must first decrypt it with a special decryption method.

How to encrypt your Android device? Do this: go to the "Settings" app, click "Security", and select "Encrypt phone". Of course, the location of this option may vary depending on the phone model.

Step 2: Reset your phone to factory settings

You can then restore your phone to factory settings (For detailed operation steps, please refer to part 2 in this post). I emphasize again, because restoring the factory settings will erase all data on the phone, so please be sure to back up all the phone data that you do not want to lose.

Step 3: Load dummy data

In fact, it is enough if you have completed the first two steps, but in order to further improve the safety factor, you can also take extra steps to load some fake photos and contacts on the device. You may ask: is it necessary to do this? The answer is in the next step.

Step 4: Factory reset the phone again

After you have loaded your phone with dummy content, you can now reset your phone to factory settings again to erase these dummy contents. If you do this, the original erased data will be buried under the dummy content, which will also make it difficult for others to restore the data that was erased after the first factory setting.

The Bottom Line

In this article, we talked about how to prepare Android phone for trade in. We also demonstrate how to wipe your phone permanently before selling. We do not recommend using a simple delete button to delete your phone data, nor use the factory reset to erase your phone content, because they are not safe to do so, and others can easily recover this data. The safest method is to use professional software such as Eraser for Android, which can permanently erase phone data. So far, this product has not been negatively evaluated. The software interface is also very simple and very friendly to novices. So guys, I hope you can find your satisfactory solution in this article to wipe your Android phone before selling.
