Lenovo may have purchased Motorola from Google, but thats not stopping it from releasing a new pair of Android-based smartphones. The company just pulled the wraps two new Vibe phones, the Z2 and the X2. In line with a number of new phones, the Z2 is being marketed as Lenovos selfie phone. It could have the right hardware to back that claim up, however: Its back-facing camera rates at 13 megapixels, but Lenovo also threw in an 8-megapixel shooter in the front.
