The Xperia T is a strange mixture of design influences and combines the refined edges of the Xperia S with the unique curved back of the Sony Ericsson Xperia Arc. The 4.6-inch screen uses Sony’s Bravia Engine to create a convincing and bold picture. Sony’s insistence that the dual-core Snapdragon S4 can match the performance of rival quad-core chipsets like Nvidia’s Tegra 3 seems credible. The rear shooter is of 13MP with Autofocus.
