I've just upgraded my old ATIV S for a new 950.
I've never used a case/cover/protector in any previous phone as I don't want any extra bulk in the pocket. And I don't care about the screen or body. My old ATIV is cracked, chipped and dented and i really don't care. Works fine in every respect bar the camera which takes blurred photos presumably due to scratched/worn camera lens.
So in the new Lumia I would like to protect the camera lens from wear.
So how to protect the camera lens? Looking at cases/covers online they just seem to have a cut out for the camera and seem more about protecting the body/screen.
