Russian website Mobile-Review published two photographs of upcoming new Xperia flagship device – the Sony “Yuga” C6603. A first quad-core effort from Sony, codename Yuga’s back panel is made of black glass and the unibody shell has a camera button. It couldn’t be confirmed if the camera itself is a 12, 13 or a 16MP shooter, but the screen is a 5-inch LCD Full HD type. The smartphone runs on a Snapdragon S4 Pro chipset and, according to reports, it gets quite warm, not unlike the LG Optimus G and Nexus 4 who sport the same quad-core technology. We expect to see more from Sony at CES and MWC in January.
