The Nexus 4 rattle!

Since Day 1 with my N4, I have heard a small rattle sound around the camera/flash location. Sometimes I'll hear it when sitting it down on a table, etc. If I shake the phone, I can hear it that way too. It sounds like something in the flash is ever so slightly loose.

Like I said, it's been doing it forever, so I've kind of just brushed it off, but lately it's become more annoying. Has anyone else ran into this problem?
