You will see an Unknown Part 
message if the camera installation is incomplete or if the camera:
- Was replaced with a nongenuine camera
- Was already used or installed in another iPhone
- Isn't functioning as expected
This message doesn't affect your ability to use your iPhone or access your camera.

AFAIK, Apple does not provide a user method to remove this message. As such, I suggest that you contact Apple Support directly for further assistance with this matter. To do so, simply select the "Support" link on the lower left-hand side of this forum's web page.
