Here we can find a video in which, through a test, it is believed to have found a small flaw in unlocking by facial 4.0 Android recognition Ice Cream Sandwich. While Tim Bray, a developer of Google, has said that it is necessary that there is a real person before the camera, it seems that in the video demonstrated that this is not true. It seems that the Galaxy Nexus used replied in the affirmative to a photo that appears on the screen of a Samsung Galaxy Note.
Some say that it is only a trick, and actually the system was programmed to recognize the picture and not a face. Of course the author of the video says that this is not true and even placed the link to a video that shows that it does not lie.
Whatever the case, if it's a failure, is not a security flaw as some may believe. It is simply unblock the smartphone without using their hands.
