From the “I bet your phone can’t do this” files comes the new underwater-friendly Sony Xperia ZR. If the name Xperia sounds familiar it’s because the Xperia ZR is an upgraded version of its highly touted predecessor, the Xperia Z. The latest version has been designed to be submerged down to 5 feet of water for up to 30 minutes. The smartphone also boasts a 4.6” OLED screen, 13 Megapixel camera, and a Snapdragon quad-core 1.5GHz processor.
