The launch of Ice Cream Sandwich bought with it many amazing features. Phone security has always been a point of discussion among android users. Some prefer the traditional pin while some prefer the pattern unlock. While few don’t believe in screen locking at all. ICS certainly bought with it a unique solution that is face unlock i.e. facial recognition. This features makes even more sense with Jellybean 4.2’s multiple user environment. As the name suggests facial recognition lock, requires you to scan your face by the device’s camera to unlock the device.
