I don't think I have the rattle... my vibration just sounds like a much stronger vibration than any other phone I have had. But it doesn't rattle, it buzzes. I quite like it. I can actually feel the dang thing in my pants pocket now. I usually miss alerts when I have my phones in my pocket and it's on vibrate only because I cannot feel them.
I agree the vibration is semi "violent" compared to any past phone I've owned but I'm actually enjoying it since I seem to leave my phone on vibrate and never use to hear it go off. Also in reference to is this design or defect, I read on another site that the rattle everyone seems to be mentioning might be caused by the camera's floating lens. No idea if true or not, but a possible explanation.
I made this video to hopefully prove that this Rattling is a defect!
Please don't let At&t work another one over on you I took mine back and got a perfect phone you should do the same. I love my 920!
Update: My new phone isn't perfect its letting dust get in under the glass. Got some inside the front facing camera, If I don't do something quick dust will be in front of the proximity sensor and the phone will be unusable.
I do get a rattle but I've always thought it was the camera lens so it wasn't a big deal. Nothing is damaged as far as I'm aware. It only rattles on larger vibrations - pressing the touch buttons does not cause a rattle.
So i was at Rogers downtown (Montreal) This morning... The guy was rude but we got to open to other phones that were phone batch 46/2013, mine is 45/2012. They ALLLLL rattled. So obviously I didn't got an exchange.
I'm waiting on news from Nokia a tech is suppose to call me back.
You fools, there is a defect here, and like what other said, it varies from each phone. Here's the link of the evident rattle issue. I to0 have the rattle issue. If you want to check how bad the rattle vibration your phone makes download the app caled "vibeMassage free" and let me know if you have a solid vibration or more of like a can being vibrated on inside the phone.
From my limited experience I've noticed it varies by color. The Nokia repair manual states that the fit of the case will vary significantly by color. It was a struggle removing the case on my white 920 but from watching YouTube videos other cases come off easily
