I just put a new housing on my curve and now get twice the amount of dust under it. It was free of dust when I put it on an now two weeks later has a visible amount. Before I changed it there was hardly any for 3 months. Is there anything I can do to prevent this? Or do I just have to take it apart and clean it more now since its not oem
