With the Mobile World Congress approaching, Qualcomm have decided to share a few new details about the Snapdragon S4 processors, which are going to be featured in quite a few mobile devices at the event. Perhaps the most important thing about the S4 is that they’re made by 28 nm technology, which makes them a lot more power-efficient. As it turns out they have a lot of other interesting features, such as support for a single 20MP camera or a dual-camera for shooting 3D pictures and videos. Another interesting camera feature is the stabilization, which doesn’t slow the camera down like on most devices. Last, but not least, the Snapdragon S4 supports all kinds of gestures, with which you can control the device by moving your body in front of the camera. B. A.
