Android 4.0 Ice Cream Sandwich is definitely the most-craved-for Android operating system today because of the great functionality and style that it brings to users. Ice Cream Sandwich has tons of features to talk about, but there's one cool feature that you will surely be curious to try–the Face Unlock feature.

The Face Unlock feature is available for those who have Android 4.0 Ice Cream Sandwich. In this article, you will know how to set up Face Unlock on your Galaxy S2 running Android 4.0 ICS firmware. But, take note that this is only applicable if you are going to root your phone, so if you are not willing to root your phone, then you will consequently not be able to set up this application.

Face Unlock Feature

The Face Unlock feature will really be a great additional feature on your Samsung Galaxy S2. When this feature was first launched, many people surely got excited to get it on their phones. On the other hand, this feature for our Android phone is more of a cool functional feature because in terms of security, this feature had been tested to be not completely fool-proof. There have been several reports of real-life incidents where Face Unlock failed to function as expected. Though, as a failsafe option, you can use a PIN code or a visual pattern to unlock your phone if Face Unlock doesn't work.
