While most people do not dream of having a phone that they can scratch at with a knife or throw at a brick wall without it being harmed, having a durable phone screen has certainly become a necessity in this day and age.
The waterproof Kyocera Brigadier has provided a solution to those who regularly drop their phones in puddles or happen to throw them at street signs. The 4.5-inch screen is called the 'Sapphire Shield' and is of the gemstone sapphire, which is the third hardest mineral in the world -- behind diamond and moissanite.
The phone has been described by Kyocera as "virtually scratch-proof" and is the first of its kind. It has been tested by Kyocera and consumers alike and the general consensus is that the Brigadier lives up to the hype.
