Waterproof Cellphone

Given that basically everyone knows at least two people who have dropped their cell phone in the toilet (or other body of water) – why don’t cell phone manufacturers make all of their phones waterproof?

Yes yes, you can buy the construction phone that’s water resistant, shock resistant, and impact resistant too. But where is straight waterproofing for everyone’s phone? I don’t want the click to talk crazy looking construction phone.

In my opinion, someone is missing out on a huge market.
