Encrypt Your Android Device

Android Encryption

In an age where an increasing portion of the population is transitioning from feature phones to smartphones (and other extremely mobile computers), it is always surprising for me to discover how few people I know actually employ encryption on their devices, particularly when it comes to Android users.

Since Android Gingerbread 2.3.4, users have been able to encrypt their device’s contents, and it’s a relatively painless process to set up. So, let’s dig in and learn how to properly secure our Android devices.

Depending on your device’s hardware, and the amount of data your drive contains, the encryption process may take up to an hour, but on most newer devices I’ve used, the process usually clocks in at under 30 minutes.

Choose A PIN

Before you begin, make sure that:

  1. Your device is plugged into a power source.
  2. You have set a PIN or password for your device. To do so, go to Settings | Security | Screen Lock, and then tap either PIN or Password.


To begin the encryption process, navigate to Settings | Security and press Encrypt phone (or Encrypt tablet) under the Encryption section.

Next, you’ll be presented with a warning screen. Just tap the Encrypt phone button to proceed.


Enter in the PIN/password you set before you began encryption. This will be the key that is used to encrypt/decrypt your device’s contents. There will be another warning you will have to agree to, and then, a progress indicator will appear to give you feedback on how far along the process has proceeded. Keep in mind that if the process is interrupted, you may lose all the data on your device.

After the process is complete, your device’s storage will be inaccessible without its associated PIN/password. Also, this key will be required whenever you boot up or reboot your device.

Encryption is a one-way process, and the only way to remove it is to do a Factory Reset on your device. For a few reasons on why enabling encryption is a good idea and what some of its consequences are, head on over to How-To Geek.
