Class Smartphone and even fits in your pocket.

About the technology and processing have been left out here enough, I do not need too.
Hab razed to the update to the latest firmware, so far after more than a week nix SOD or Phone is hot. I think Sony has the error probably finally corrected.

Important and buying decision was for me, as I said in the title, the size and especially the dust and water tightness. Do I need for my outdoor work and my hobby.

When you first pick it up, I was very surprised how easily the XV is, my old 5800XM
was, although much smaller, about the same weight.
It's good to use with one hand, the side buttons are easily accessible.
The first call in the pouring rain has also survived without difficulty until now I have nothing negative found.
I particularly like the design, it stands out from all the other Smartphones with rounded edges,
and not everyone has it.
For the introductory price of, I think, about 500 I would not have bought it, to the current price
I give a strong buy recommendation.
