I had dust under my original one. My replacement doesnt. Thank good because the FRU brown box that it came in had cardboard pieces and particles in it.
How long will it stay dust free? I have no idea but I'm trying to do my best on preventing it. For instance, if its laying on the desk, I'll place a paper or microfiber over the screen or something until I can find a case that has a clear plastic that covers the screen and phone/gap
