If not someone should make it, a card slot at back that acts like a stand and a front cover that pops on front of the phone and acts like a screen protector, that protects it against water. That's my dream case, well that and a battery charger case built into it.
There must be one out there.
I know otterbox has a commuter card case for s5. Not sure if you can add one of their pop in plastic screen protector things and not sure if it's coming to note 4 but it might be something to look into.
