I get the facial recognition thing to activate by tilting my head to the side. The face in the bottom left corner just means that your 3ds recognizes that there's a face in front of the camera. Try pulling your device a little further away from your face to make the icon come back if it's not there, I have to do that sometimes because I have bad eyesight and I hold my 3ds screen right in front of my face when I'm playing.
