Some time back, the FBI was heard to say in public that draw-your-passpattern security, as seen on Android smartphones and tablets, was too much for them, at least as long as you kept your screen clean of skin oil. :-) Whether or not that's true, there are apparently ways to attack even that, using just the sensors on the platform.
