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.
