It runs Android 4.2, packs in 802.11n Wi-Fi and Bluetooth 3.0, and benefits from a fast charging feature that juices up the 2500 mAh battery in just 90 minutes.

To the front is a 2-megapixel camera with an 88-degree viewing angle. Round the back you'll find a 13-megapixel camera that makes use of a Sony Exmor BSI sensor stack and wide aperture F1.8 lens. It's capable of up to 10 frames per second continuous shooting, and has a feature set that includes a mode which captures five images in quick succession and allows the user to remove anyone or anything that might have moved in front of the subject while the shot was taken. This camera is also capable of recording Full HD video at 30 frames per second.
