Released nearly a year apart, the Sony Xperia S and the Samsung Galaxy S II are not that different - both are flagship droids with dual-core CPUs and 4.3" screens. But the newer Xperia S brings some fine upgrades, like the 12MP camera and the 720p screen.
Still, the Galaxy S II is the outgoing Samsung flagship while the Xperia S is the best and the brightest of Sony's new NXT series and will be for a while longer, so it will have to fight off the onslaught of quad-core droids headed to market.
Processor aside, the Sony Xperia S brings a high-pixel-density 4.3" screen with 720p resolution and Mobile BRAVIA engine. Then there's the 12MP camera with 1080p video recording, a notable advantage as most new recently announced phones use 8MP shooters. There's also excellent connectivity and so on.
The 1.5GHz dual-core CPU and Adreno 220 GPU showed promising performance, beating most dual-cores too. Here's the summary of the pros and cons of going for the Sony Xperia S.
