X Touch Face Unlock to let the phone capture your face.
You can unlock the screen by looking at the front camera.
You also need to set a pattern or PIN in case the phone
cannot recognize your face.
X If you touch Pattern, you’re guided to create a pattern you
must draw to unlock the screen. The first time you do this,
a short tutorial about creating an unlock pattern appears.
Then you’re prompted to draw and redraw your own
pattern.
X If you touch PIN or Password, you’re prompted to set a
numeric PIN or a password you must enter to unlock your
screen.
IMPORTANT: If you forget the pattern you set, try five times and
touch Forgot pattern? to sign in to the Google Account you have
added on the phone and reset the screen lock. You need an
active Internet connection.
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.
