Protecting Your Phone With Screen 
Locks 
You can protect your phone by creating a screen lock. When 
enabled, you need to touch and hold certain icon, draw a pattern 
or enter a numeric PIN or password to unlock the phone’s screen 
and keys. 
1.  Touch the Home Key > Menu Key > System settings > 
Security. 
2.  Touch Screen lock. 
3.  Touch Long press, Pattern, PIN or Password. 
  Touch Long press to enable screen lock and allow 
unlock with a ‘touch and hold’ gesture. You can unlock the 
screen by touching and holding    on the display. 
  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.
