Security is always a big concern of having a smartphone. Unlike before, if one gets access to your smartphone he can basically can get a control over your entire life; emails, SMS, other important accounts, contacts, etc. So it is always important to setup a good secure password on your Android device. However there should be a good tradeoff between convenience and security. The password shouldn’t be so difficult that unlocking screen becomes a painstaking task.
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.
