Android 4.0 introduces a new way of locking smartphone devices using facial recognition.
Face Unlock allows users to unlock devices using facial recognition technology.
“It takes advantage of state-of-the-art facial recognition technology to register a face and to recognise it later when unlocking the device. Users just hold their devices in front of their faces to unlock or use a backup PIN or pattern,” said Google.
