Protecting Your Phone With Encryption
You can encrypt all the data on your phone: youraccounts,
application data, music and other media, downloaded information,
and so on. If you do, you must draw a pattern or enter a numeric
PIN or a 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 pattern, 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:

Touch the
Home
key

> Settings > Security > Encrypt
