I recently shipped out a Smartphone Floater to a customer that has a Samsung Note8 phone. His immediate concern was that he was going to flood the box and ruin his phone. I've been making a type of floater box for iPhones for the past six years or more. I'm sure in that time, someone has had an accident and got water inside the box because not everyone is perfect. That being said, I've never had that problem. I put the phone in the box, place it on the surface of the water and hold it where I want to take a picture.
