Not really a review but close Read the Preview
Here the conclusion:The Sony Xperia S is worlds ahead of the previous Xperia generation and we're genuinely impressed. It's a proper premium droid and would have been absolutely spectacular mere months ago.
The Xperia S hasn't got a quad-core processor (not even a next-gen dual-core) and it only comes with Android 2.3 Gingerbread out of the box for now.
But here's what the Xperia S has going for it: the screen is nothing short of amazing, the camera is one of very few to offer 12MP resolution and the connectivity has plenty of useful features. And Sony really managed to squeeze every ounce of performance out of the Snapdragon chipset inside. Last but not least, we do like the new design line too.
The phone looks great and the build quality is worthy of a flagship. If you can get over the lack of two extra cores and ICS at launch (the update is coming), there's plenty to like about the Sony Xperia S.
