HTC has basically been granted a patent on Face Unlock. This is interesting, because that feature was first added to Android by Google, in its 4.0 release. It has subsequently made its way onto the very few devices that have so far been updated to Android Ice Cream Sandwich, but also to the Samsung i9000 Galaxy S and the Samsung i8150 Galaxy W via ‘value pack’ updates recently.
