FBI Fingerprint is a fun-making tool with gorgeous FBI user interface, to make your friends surprised by your powerful android phone!
How to play:
When the FBI FingerPrint screen pops up, touch your finger to the screen to be "scanned" for your identity, there will be vibration and beep sounds during the scan. After three (default) beeps/vibrations, remove your finger from the screen, you can unlock the phone!
Make Sure your friend does not see the Guide! :) Have fun~
