With less than three weeks to go before the Mobile World Congress 2015 in Barcelona, tech experts as well as enthusiasts are eager to know about the gadgets that various tech manufacturers would be unveiling at the event. Recently some spotted the purported Vive Z3 Pro, the upcoming smartphone from the Chinese tech giant Lenovo, in a social networking site called Weibo.

According to Christian Today, the leaked photograph suggests that the Lenovo Vibe Z3 Pro will sport a 5.5-inch quad HD screen display, which will be smaller compared to the 6-inch display screen of its predecessor - the Vibe Z2 Pro. In addition, the leak revealed that Lenovo's upcoming flagship smartphone is powered by Qualcomm Snapdragon 810 processor coupled with 4 GB of RAM. The device will have an internal storage capacity of up to 64 GB, which is expandable via a microSD slot.

Lenovo Vibe Z3 Pro will come with a 16-megapixel rear camera with optical image stabilization as well as laser focusing. According to the leak, the camera of the upcoming device will feature a shutter button - something very rare these days. One thing seems to be certain and that is the smartphone will run with Google's latest Android 5.0 Lollipop OS. In addition, Vibe Z3 Pro will reportedly pack a 3400 mAh battery.

The look of the Lenovo Vibe Z3 Pro is certainly one of the USPs of the device. According to the leaked photos of the device, the handset definitely beats others with its all glass and metal casing. However, the back panel of the device - brushed aluminum, is similar to that of its predecessor, but the curved edges of Vibe Z2 Pro have been replaced with sharper ones.

As suggested by the timing of the leaked information and images of Vibe Z3 Pro, Lenovo is likely to announce its launch at the upcoming MWC trade show, which begins on March 2.
