Lumia 900 glass is harder than nails "literally"

Yes . Nokia wanted to prove the hardware validation
of it's newest Smartphone Nokia Lumia 900

and here as we see the screen is harder than just nails
to scratch it it's harder than a hammer going with the nails .
As we all know from the leading Mobile phones company Nokia has shown us this picture from it's labs
from the Nokia conversations .
Nokia has got this idea from looking the Sonim
Sonim is a company makes tough phones designed to tackle extreme conditions and has been demonstrating phones by hammering nails into them for years. But this is the first time we've seen a consumer smartphone repeat the trick.
