n900 camera cover mystery

Camera in my n900 stopped working ... "Open lens cover", but opening it did not help. I removed the back cover, and voila, camera works. Then I seen loose piece of metal, and figured that it probably causes it.

Today I studied lens cover in greater detail, and appears to use optical sensor to tell if lens is closed or not. "Lens always open" is better failure then "lens always closed", so I put a piece of paper in there. Optical sensor should be blocked now. Weird thing is that camera cover now works, reliably as far as I can tell. It somehow detects the cover through the piece of paper. I wonder what kind of magical x-rays it uses...
