7D2 - loose screw or something else?

[Ruined]

Just received a new 7D2 body from amazon. When moving it (haven't even attached a lens or put in the battery), it sounds like a screw is loose near the hot shoe area. Is this a noise from an accelerometer (or similar sensor) or is it likely I received a defective camera?

It's the guide rails for the pop up flash, same issue with mine. Try opening the flash and rattling it around again, the sound should stop. apparently designed so the rails don't seize but I am sure they could have done something less noisy

Interesting, I figured something like this would be more likely than a loose screw. Thanks.
