This morning in Barcelona at the Mobile World Congress, 27th February 2016  Sony Mobile Communications (“Sony Mobile”) today unveiled two stunning super mid-range models in its refreshed “X” series, Xperia XA1, and its 6” screen big brother Xperia XA1 Ultra. Building on the success of last year’s XA models, the XA1 and XA1 Ultra feature a beautiful borderless design to make the most of the edge-to-edge screen, cameras that are worthy of a high-end premium status and octa-core processors.
