It also features an 8-megapixel rear camera, 1.3-megapixel front-facing snapper, 21Mbps HSPA, 802.11 b/g/n Wi-Fi, 16GB of storage, NFC and Bluetooth 4.0. Worried about the pitfalls with battery drain with this one? Well, the handset packs a hefty 2,150 mAh battery to hopefully give it enough juice to get through a day.
