Using Your Fingerprint 
With the fingerprint sensor on the Power key of your phone, you 
can register up to 5 fingerprints and use them to unlock the 
phone or open a bound app when the screen is off or locked. You 
can also use the touch-controlled function. 
  NOTES: 
  The fingerprint feature is usable only when a screen lock 
(Pattern, PIN, or Complex password) is enabled. When the 
screen lock is reset to None or Swipe, all registered 
fingerprints are erased. 
  If you restart your phone, you need to enter the screen lock 
pattern, PIN or password you set to unlock the screen for the 
first time.

4.  Follow the prompts to record the center and the edges of a 
finger.
