Two Nokia engineers decided to hammer a nail onto the Lumia 900’s display. After some pounding, the screen continues to work properly. In the second test, the handset’s display is used to pound a nail into a piece of wood.
The Nokia Lumia 900 uses the Corning Gorilla Glass, an alkali-aluminosilicate material designed to be damage-resistant, lightweight and thin. Experts said that it is about thirty times harder than plastic and comparable in strength to sapphire.
