I've actually taken to just waving my hand over it when I want to know the time (which works even in the dark). I sometime do that without thinking on my daughter's iPhone and stand there blankly when nothing happens.

That's cool! Does it sense the heat or movement I guess?
The sight filled the northern sky; the imensity of it was scarcely conceivable. As if from Heaven itself, great curtains of delicate light hung and trembled. Pale green and rose-pink, and as transparent as the most fragile fabric, and at the bottom edge a profound fiery crimson like the fires of Hell, they swung and shimmered loosely with more grace than the most skillful dancer. ~ Northern Lights
Phones often have an infra red light next to the earpiece to detect when it's near your head (to stop your face touching the screen and doing things while on a call). Could be using that as the sensors in the cameras can see infra red. A good way to test a remote control is working is to hold it in front of your phone camera and press a button, when you will be able to see the light flashing.
