What are these dots on my Optimus V?

I was playing with my phone one day when the sun shined on my phone and these 2 black dots appeared. These are located in the top left corner of the Optimus V. I have no idea what these are nor what they do. First I thought they were LED lights but I guess not. Anyone know? Thanks.

Proximity sensor. It turns the screen off when you put the phone to your face. My guess is that one of the holes is an IR led while the other is an IR sensor. When your face reflects back the light, the screen turns off during calls.

So if one of them is a LED then how do you set it to work?

You don't.

IR LED = infrared LED = invisible to the human eye

lol, I would say proximity sensor for 1 hole, and the other hole is a light meter to tell how bright/dim it is outside.

It is definitely an IR LED. What do you think the proximity sensor is sensing? You can verify by looking at the dot with a digital camera while making a call. Digital cameras can see into the infrared much better than the human eye. It should be blinking like mad.

This might actually be a way of diagnosing the problem with the CM7 and the proximity sensor. Lets see if the the LED is blinking consistently.
