This is my first Android smartphone. I had an iPhone I had acquired quite by accident, and I have never been packaged. I find that this device suffers only little slower for Internet browsing (of course there is also the operator for something). For menu navigation (OS) is perfect. The HDMI connection works perfectly, without having to install (one branch and was the postponement of the smart display on the device screen). For the phone function, and yes he even phone, I'm pretty impressed. I hear perfectly well, with or without the speaker even though we all know today that our voices in these devices is very flattering. None of my correspondents had yet to complain about the micro of the Xperia S. I was a little disappointed lately sound "made in sony". Here it is repaired, at least regarding this device. I think my opinion is not taken into account by the regulars of Android smartphone, because, I repeat, this is my first Androphone. I am satisfied with my purchase. A star less so for the famous defect described everywhere and for the three "keys" bottom - back, home, menu - which require time to adapt to not having to ask them to answer three times before a result. After two days, however, is no longer a problem.
