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
organisations. 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 screen lock 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. Touch the
Home
key
>
> 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'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.
