It seems that the Blade V2 is an improved version of the Blade Vec 4G that was released last year. The most significant improvements include the presence of a quad-core Snapdragon 410 processor (instead of the Snapdragon 400 that's powering the older handset), and a 5 MP front-facing camera that lets you take selfies using gesture controls. There's also a slightly larger battery: 2400 mAh, instead of the 2300 mAh one of the Blade Vec 4G.
Running Android KitKat, the ZTE Blade V2 sports a 5-inch display with 720 x 1280 pixels. Furthermore, it features LTE connectivity, Bluetooth 4.0, a 13 MP rear camera with LED flash, 1 GB of RAM, and 8 GB of internal memory.
ZTE didn't say when and where the Blade V2 will be launched. However, since the promo video that presents it - embedded below - is in English, we assume the handset will be available internationally.
