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.Keep the phone connected to the charger.
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.
