Lenovo's Tech World just wrapped up in San Francisco, where the company unveiled three new smartphone options for their customers - the Phab2, Phab2 Plus and Phab2 Pro, which all come in 6.4 inch screens. In the Phab2 Pro, Lenovo has introduced the use of Tango, a Google's camera system that is able to detect objects as three-dimensional items.

How it works, as reported by BBC, is that the Phab2 Pro's sensors are able to make sense of the objects as well as near spaces. The Tango technology is also capable of depth-sensing and motion-tracking, which is added to both the front and back cameras of the Phab2 Pro.

However, as the publication notes, the stage demonstration of the Tango technology proved to be a little difficult. It took several tries before the software locked onto the object. The items in motion also froze midway throughout the demonstration.

Lenovo stands by its decision to incorporate this technology, as it believes that it will open up several possibilities in gaming and design. Particularly for games, the company argues that characters can be superimposed over a view of a certain room. As for interior design, it would prove practical as users can theoretically see and move 3D models of furniture over an area of a home.

The items are to go on sale this September, so Lenovo still has some time to fix these areas for improvement.

According to GSM Arena, the Phab2 and Phab2 Plus do not come with Tango, but are still compelling items, especially in the affordable smartphone market.

The Phab2 has a 720p IPS screen, a quad-core MediaTek 8735 CPU paired with 3GB of RAM and 32GB of internal storage, with the option of extending via a microSD card and an 13MP camera. On the other hand, the Phab2 Plus is slightly better with its 1080 IPS screen, a quad-core MediaTek 8793 CPU.

The Phab2 Plus also comes with a dual camera setup for changing backgrouns, refocusing after images are shot, laser autofocus sensor and a rear mounted fingerprint scanner.
