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.
3.
Plug in your phone.
4.
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:
24
5.
Touch the
Home Key > Menu Key > System settings >
Security > Encrypt phone
.
6.
Read the information about encryption carefully.
The
Encrypt phone
button is dimmed if your battery's not charged
or your phone's not plugged in.
If you change your mind about encrypting your phone, touch the
Back Key
.
WARNING! If you interrupt the encryption process, you will lose
data.
7.
Touch
Encrypt phone
.
8.
Enter your lock screen PIN or password and touch
Next
.
9.
Touch
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're 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.
