security, although it can be more convenient than the
stronger options.
Remember the pattern, PIN or password you set. Otherwise,
you will have to upgrade the phone software to use the
phone.
Protecting Your Phone With Encryption
You can encrypt all the data on your phone: your accounts,
application data, music and other media, downloaded
information, and so on. If you do, you must draw an unlock
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 pattern, PIN or password you set for
encryption is controlled by the system administrator.
Before turning on encryption, prepare as follows:
Set a screen lock pattern, PIN or password.
Charge the battery.
