Protecting Your Phone With Encryption

You can encrypt all the data on your phone: Google accounts, application data, music and other media, downloaded information, and so on. If you do, you must enter a numeric PIN or password each time you power on your phone.

WARNING! Encryption is irreversible. The only way to revert to an unencrypted phone is to perform a factory data reset, which erases all your data.

Encryption provides additional protection in case your phone is stolen, and may be required or recommended in some organizations. Consult your system administrator before turning it on. In many cases the PIN or password you set for encryption is controlled by the system administrator.

Before turning on encryption, prepare as follows:

1.

Set a lock screen PIN or password.

2.

Charge the battery.

When you’re ready to turn on encryption:

1.Press the Home Key > Menu Key > System settings > Security > Encrypt phone.

2.Read the information about encryption carefully.

The Encrypt phone button is dimmed if your battery is not charged or your phone is not plugged in. If you change your mind about encrypting your phone, press the Back Key.

WARNING! If you interrupt the encryption process, you will lose data.

3.Tap Encrypt phone.

4.Enter your lock screen PIN or password and tap Next.

5.Tap Encrypt phone again.

The encryption process starts and displays its progress. Encryption can take an hour or more, during which time your phone may restart several times.

When encryption is complete, you’ll be prompted to enter your PIN or password.

Subsequently, you must enter your PIN or password each time you power on your phone to decrypt it.
