I carry my phone in a holster on my belt, no waterproofing at all. But then, I don't wear it when I am on the water. It is turned off and in a sealed quart freezer bag inside my gear bag, just in case I do need a phone. Now then, my camera is a different story. I have a Pentax GPS WG-II waterproof/shockproof camera. That is always with me on the river, ready for instant photo taking.
