So, I own two Lumias. Mine, a black one, and my girlfriend's, a cyan one. My vibrate has that disgusting, something-is-loose rattle when it vibrates. Most of you have experienced the same thing, so I thought it was normal. However, hers doesn't do it. Today I went to my AT&T store, and none of the rep handsets did it either. So, I exchanged mine, it appeared to not do it. But, after having it for some time, it does it, and it's driving me crazy. What is driving me crazier, is that their handsets rattled when flicked near the camera, but didn't rattle on texts, calls, etc. It is so god damned annoying now lol. Have any of you figured out WHAT is rattling? Or how to stop it?
