Sony has announced a variant of the Xperia E4 called the Xperia E4g , which will include 4G LTE support. The Xperia E4g has a smaller 4.7-inch qHD display, versus the 5-inch qHD display on the Xperia E4. The Xperia E4g is therefore a smaller handset, but marginally thicker at 10.8mm (Xperia E4: 10.5mm). Other small changes include the addition of NFC and a higher processor clock speed of 1.5GHz quad-core (versus 1.3GHz on the original). The new handset will be available in both single SIM and dual SIM ( Xperia E4g Dual ) variants. It is due to launch in April 2015 for €129 and will be available in black and white colours.
