Setting an Unlock Pattern
Creating a screen unlock pattern increases security on the
phone. When you enable the User visible pattern field, you
will draw an unlock pattern on the screen whenever you
want to unlock the phone's buttons or touch screen. When
you activate the User tactile feedback field, you feel vibration
as feedback while drawing the pattern.
The feature is now paired with a backup PIN code that acts
as a backup to the pattern lock. If you forget your pattern,
you can regain access to the device by entering a PIN code.
Note: Make sure the Require Pattern field is activated.

point. Then, without removing your finger from the
screen, drag your finger over adjacent points until the
gray trace line overlaps each point and they are
highlighted with a green circle.
