Waterproof? I think not

Last week I dropped my phone in about a foot of water and retrieved it within 10 seconds. The rating says it's good for a meter deep for a half hour. Nope, totally bricked it. It entered the blue screen of death, you could see water behind the camera lenses, and it wouldn't shut off until the battery died. So glad my wife got me the care plan, I got a free replacement.

Now I'm looking for a waterproof solution. I need it to be accessible because I use the mapping while in my canoe. I've tried the clear vinyl pouches but it's impossible to see the screen in daylight. Do the hinge protector cases do anything regarding water?
