This may be a total noob question, but I was just curious to know the exact location of the light sensor because I cant seem to figure out where it is located.
That dot that looks like a front facing camera (FFC) - that is your sensor there that controls screen on/off on calls and the auto brightness.

Are you sure, because when I ran sensor test that dot did change the proximity sensor values, but the light values wouldnt change even if I covered it completely.

The only way I was able to change the light value was to move the whole phone into a darker or brighter location, but not by finding a pinpoint sensor on the phone.

Edit 2: When I cover the proximity sensor dot (the obvious one) with my finger and shine a light at the phone, nothing happens, and when I remove my finger from the dot and shine a light right on it, the screen gets brighter. I suspect both sensors are in the same spot (the plastic dot you see probably transmits ambient light to the light sensor as well as housing the proximity sensor, in the way many computers use a little clear/frosted plastic piece to indicate the status of an LED that is buried in the chassis.

Try it with a flashlight and see if you get different results.

If you are interested in disabling the light sensor go into settings and manually set your brightness.

I have to say the proximity sensor works much better than on my Hero.

The light sensor is just to the right of the proximity sensor under the speaker grill. Turn on auto-brightness and test it with your finger.
