Nokia is famous for the build quality and strength of its devices. However, it is doubtful that anyone thought a phone would survive what a Nokia Lumia 900 was subjected to this week.
In a video, that has since gone viral, it shows someone hammering nails into the screen of a Nokia Lumia 900 with reasonable force.
To reinforce the point, the screen of the smartphone was then used to hammer a nail into a wooden plank.
Throughout the process, the phone's screen remain intact, and seemingly free of any scratches.
As smartphone contracts often last 24 months for flagship devices, a well built handset, that is unlikely to chip or scratch, is a must.
The Lumia 900 features ultra tough Gorilla Glass, which was first used in the original iPhone after Steve Jobs found hard plastic screens to be unsatisfactory.
The Gorilla Glass covers the 4.3in display of the handset, and yet the weight of the device is only 160g, just 20g heavier than the 3.5in iPhone 4S.
The Nokia Lumia also boasts an 8 megapixel camera, with Carl Zeiss optics and HD video recording. It runs Windows Phone 7.5 Mango, and has 16GB of internal memory, 512MB of RAM and a 1.4 GHz Scorpion processor.
