I've got an idea to fix the crappy automatic brightness sensor on my Android phone. Will it work / screw anything up?

OK, so this explanation
of why auto-brightness doesn't work on smartphones makes perfect sense. The little brightness sensor lens has a very narrow field of view and essentially can only measure how illuminated your face (or the room behind you) is, not how bright the phone background or screen surface is.
It seems to me a quick fix would be to modify the sensor so its field of view is a little wider, more of a fisheye, so that it at least would get a more average reading across the whole room (instead of a spot measurement of a dark corner or bright light fixture).
My plan is to carefully mask and sand the phone face above the light sensor to a matte/opaque finish. Do you think this will work to force the light sensor to capture a wider field of view? Is this what I want, anyway?
