This piece of glass with what looks like a Window cut is a concept Phone released by Seunghan Song, called the Window Phone. This fully transparent body is pretty cool, and the water beads on it are not to show off what it is waterproof, but the water beads displayed by the phone tell you that it is raining outside... Of course, if there's nothing up there, it means sunny... Moreover, you can interact with the phone to tell it what the weather is actually like, for example, you tell it "snow" and then it gives you snowflakes on the screen...
