Walked out? Doubtful, that's what cell phones are for.
Sometimes when people are pushed into the water their cell phones get wet and don't work.
Most wise men that spend much time on the water keep their cell phones and wallets in watertight bags or boxes.
That's true. I am not on the water but when I go for a walk in the mountains with the dog, if it looks like rain, I put my phone in a quart Ziploc bag. If you took a dunking in waist deep water that ziploc bag would certainly protect the phone for the minute or two it was under water.
