HTC unveiled three models of its new One-series smartphones – the HTC One X, One S and One V – at the Mobile World Congress (MWC) 2012 recently.

The HTC One series integrates Android 4.0 (ICS) with HTC Sense 4, the new version of HTC's branded user experience that is introducing HTC ImageSense, a new suite of camera and imaging features. HTC Sense 4 also includes enhancements to audio quality and simplifies how people listen to music on their phone, HTC claimed.
