I put my finger over where I think it is, and it doesn't seem to lock the screen. I've only made one phone call with the phone so far, so I can't comment on how well it prevents face dialing, but shouldn't it lock the screen if I cover the sensor?
Or is it so advanced that it can tell the difference between my finger and my cheek?
