My lovely, pristine, Lumia 930 slipped out of my pocket getting in the car this morning, and fell onto the hard concrete of the drive. I've only had it 3 weeks since the insurance replaced the one I lost! Anyway, it held up remarkably well, with just a couple of little dings in the aluminium rim around the phone. However, the volume up button is now feeling kind of weird. It works, but it doesn't have that satisfying click of the other buttons. Any idea how I can solve this?
