It's always possible to damage hardware, but the RasPi folks have a really good QA process to make sure hardware works before they let it out the door.
Try lifting and re-seating the little flex cable between the camera and the PCB. That one can work slightly loose in packing and shipping.
If that doesn't work, send a note to email@example.com
and we'll get you another one.
When you void a product warranty, you give up your right to sue the manufacturer if something goes wrong and accept full responsibility for whatever happens next. And then you truly own the product.
