Blink for face unlock

Jelly Bean has improved the facial unlock feature by creating a setting whereby you must blink when unlocking your phone. This prevents fraudsters using a photo of yourself and holding it up to the phone.

To activate this feature go to Settings – Lock screen – Screen lock – Face unlock. Then setup your facial unlocking.

Then once that is done, go to Face unlock again and tick Presence check.
