what are the two dots above the ear piece

No, that's not the dot I refer to.

The camera is directly to the left of the earpiece (that is most obvious). Look dead center, directly above the earpiece, and there's a dot. I believe this is the proximity sensor. Directly to the left of that is a slightly smaller, dot. After a bit of digging, I think I've determined that this is the ambient light sensor.

The image below ISN'T a 6, but it's the best approximation I could find showing the spatial relationship of everything.

The larger one in the center is the proximity sensor. I'm not sure what the smaller one to the left of it is.

The other one is the front-facing camera, though on my iPhone 6 it's the other way around. That's the larger one.
