Encrypt Phone 
You can encrypt all the data on your phone 
such as 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: 
 Set a PIN or password as screen lock.
 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.
