What are these dots on the front!

Ok, the four dots on the front and top of the droid's screen.... from farthest right to left are as follows...led, light sensor, then Im not sure...and the most farthest left I think is the proximity sensor.

If anyone knows what each one specifically is, that would be great. I can't even think of what the fourth could be besides a front camera.

Sorry if this has already been discussed.

From right to left; LED, light sensor, both "dots" on left of speaker are proximity sensors. Cover either up and screen goes black. And don't worry about asking questions, we were all new once.
