An image of the soon-to-be-unveiled Huawei P9 has surfaced online, revealing the flagship smartphone will house dual camera setup.

Popular Twitter spy Evan Blass (aka @evleaks) has got hold of the Huawei P9's photo showing the rear of the device. In the image, we see the metal-clad phone featuring two cameras placed side by side on the left side, having dual-tone LED flash, laser autofocus and Leica's name engraved on the right side.

We can also see the device featuring a Huawei brand name and on top a square-shaped fingerprint sensor, just below the camera module.

It looks like Huawei P9's USP will be the camera. The additional camera sensor besides the main camera module of the device will be used to capture detailed depth information of the scene, enabling user to re-focus objects on the photos through a photo application.

For the uninitiated, Leica is a renowned German optic firm known for its top-notch rangefinder cameras.

There is already a handful of dual-camera-based smartphones in the market, but the use of Leica-branded shooters will certainly make Huawei P9 stand apart.

Other expected features of Huawei P9:

From what we have gathered so far, the the upcoming Huawei phone is expected to sport a 5.2-inch full-HD display on the front, a fingerprint sensor, the company's proprietary HiSilicon Kirin 950 processor, 3GB RAM, 32GB storage and a 3,900mAh battery.

Rumour has it that Huawei P9 will be accompanied by another higher-end model tentatively titled P9 Premium, which is said to boast a top-notch processor and high-capacity memory. It is said to feature the powerful HiSilicon Kirin 955 SoC (System-on-Chip), sumptuous 4GB RAM, 64GB/128GB storage and a USB Type-C port.

The company has confirmed it will unveil Huawei P9 April 16. Since the launch event is almost two weeks away, the Chinese firm is expected to tease key features of the device to drum up excitement among fans.
