Is the cover on the flash and heart rate sensor plastic or glass?

I'm thinking plastic, but I am curious. It's got a different feel to it than glass.

Assuming they are using the same material as used on the camera... its glass. However out of the box there was a plastic protective film covering the sensor and around the camera sensor.

I would have assumed glass but after noticing some very fine scratches and slight inconsistencies in the surface smoothness I'm going with plastic.
