Rattle

Just curious I know my some of my really old phones (aka iphone 4s) had a rattle to the camera when you shake it, unless you open the camera app. My note 5 does the same, any one else hear it. I'm not returning it or complaining, just curious if anyone else hears it. It's not all that loud.

Rattle sound

Hi, I hear a light rattle sound while shaking my phone., is this normal on the fire phone or is it just me?
Thanks.
