I’m not either, but you’d have to figure out an extremely special way to create a water-resistant phone with battery contacts that would not corrode on contact with water.

My Nexus 7 has a pop out cover, yet when it fell in a stream of running water, it never even shut down. Opening it revealed only two small drops of water.

Plus, battery contacts don't corrode from a short exposition to water (otherwise, so would the headphone plug).

Battery contacts and headphone contacts are usually gold plated, so corrosion is not really an issue.

I have a Nexus 7 as well and I have no idea what this pop out cover means. Can you please help me understand? Thanks

Sorry, probably a wrong name, I mean the back cover just snaps together (and can be removed easily, even with one's nails) rather than having screws and such.
