Estel, if there is a possibility of going all Vertu with a metal case is there any possibility of also changing the glass inside the digitizer for Sapphire. I have a watch with a sapphire crystal and it just doesn't break, watch wacked repeatedly against a cast iron stove, nothing, not even a mark. Unfortunately the scratch resistance would be below the surface.
Al or Ti case, Al2O3 screen, and a Neo900 board would be the most insane phone ever considered.
If the plan is to mill would graphite/epoxy be possible for RF?
Also if graphite is possible a slight depression could be added for inductive charging inside the door.
