FWIW, I've had really great success with the Galaxy S7 series for waterproofness, including one stint where it fell out of my pocket while jumping off rocks in the Green River where it spent at least 10 minutes submerged under 4-6' of water while we made repeated attempts to swim to it and grab it (strong currents made this way harder than it sounds). Down side is that the front/back glass aren't really drop resistant (I've killed 1 by breaking the back, which eventually succumbed to water ingress, and the other has a broken corner on the front which hasn't yet impacted usability)
