Xperia Z, Waterproof and Dustproof?

Sony claims that their newest android smartphone is a water and dust resistant, is it realiable enough to be proven? To prove such thing, Sony has uploaded some videos showing evidence of their controversial statement.

In the first and second video, we can see Xperia Z has watered by the water and wine for couple of second. The result is quiet shocking, Xperia Z is still able to work properly.

In the third video, the challenge looks harder than before because the Xperia Z is being dropped by various materials made of glass and gravels. The tremendous result is surprising. The device will have no effect at all. It still looks good and work properly.
