Sony Xperia ZR
As cool as it would be to make an underwater phone call, it’s just not practical. It is, however, technically possible with the Sony Xperia ZR which is water-resistant for half an hour to a depth of five feet. Dust, scratch and shatter-proof too, it boasts a 4.6-inch HD display, 13 mega pixel camera, a 16x digital zoom, Walkman, album and movie apps and takes incredible pictures and video under the waves. It’s one very smart smartphone.
