There are no note 5 camera lenses available at the moment. I damaged my rear camera glass and the camera itself.
I replaced the camera in the device and used an s6 glass lens for the present time until parts are available. It works fine albeit the lens is noticeably too small.
Merely pry your old shattered lens off as it is held on by adhesive and stick the new one on! Hopefully this helps anyone who was in a similar predicament as I was.
The rear camera module is readily available online if you happened to have damaged it.
