Japanese handsets are built to last. This has been mandatory in Japan for ages. No serious Japanese company would manufacture a mobile phone that is not waterproof, dustproof and scratch-resistant.
However, Fujitsu took this a little further and showed us that their Arrows smartphone, dubbed world's slimmest Android smartphone (6.7mm), can withstand... falling iron balls.
The phone's 4.0-inch WVGA AMOLED capacitive touchscreen features Corning Gorilla Glass which makes it highly resistant to scratching and accidental drops.
This type of hardened glass with high rigidity aims to preserve the display from even the most dangerous situations.
That, or you may be the unlucky one to have your screen broken the first time you accidentally drop your phone.
It is also worth mentioning that the phone's battery cover is coated with peel-resistant and scratch-resistant "ultra tough guard."
