Motorola Droid 4 :: Round Copper Piece Poking Out Of Slide Groove?

I just noticed today that my phone doesn't really seem to be closing completely. It looks like it's closed but I remember it almost snapping into the closed position so that it doesn't keep sliding open so easy.So, I flipped it over and noticed there's this peice of copper poking out right at the end of the slide groove at the bottom of the phone. It kind of looks like the end of a wire or something, almost like it's supposed to make a connetion to something else. And to me it seems out of place, like something got knocked loose or got unattached. But I don't want to mess with it too much. I poked it with a pencil and it does move a little but I can't seem to move it out of the track, so I'm leaving it alone. I haven't even had my phone 4 months.
