The Lenovo Vibe Z was previously known as K910 and sports a metal body and a design similar to the Vibe X, which the company hopes to appeal to the younger demographic outside China.
The Lenovo Vibe Z sports a 5.5" display of 1080p resolution. The phone is powered by the a 2.2GHz Qualcomm Snapdragon 800 chipset, 2GB of RAM and Adreno 330 GPU. As you'd imagine, this configuration runs Android 4.2.2 Jelly Bean without problems.
At the back, there's a 13MP camera with LED flash, which is similar to the one found on the Lenovo Vibe X. At the front, there's a 5MP snapper. The phone measures just 6.9mm thick, but battery size hasn't been detailed yet.
Lenovo has announced its plans to update the device to Android 4.4 KitKat in the future. Specific plans aren't yet revealed, as isn't the pricing and availability of the Vibe Z.
