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 more. 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:
• Set a lock screen PIN or password.
• Charge the battery.
• Keep the phone connected to the charger.
• Schedule an hour or more for the encryption process.
You must not interrupt it or you will lose some or all
of your data.
When you’re ready to turn on
encryption:
1. Press the
Home Key
>
Apps icon
>
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.
