Lenovo Phab 2 Pro first look's Al Sacco goes hands on with the Lenovo Phab 2 Pro, the world's first smartphone that supports Google's Tango AR platform.

The phab 2 pro hardware is fairly standard. It has power, and volume and up and down keys on one side, a SIM card tray on the other, and speakers and micro USB port on its base.

The fingerprint scanner and triple camera array on its bac side are probably the most notable hardware features. Those three cameras, along with front facing shooter, are the heart and soul of Tango.

The speakers offer Dolby Atmos sound, and the phab 2 pro's is the first smartphone with a mich that captures Dolby 5.1 audio , according to Lenovo.

It's massive QHD display is 6.4 inches, making it just as much a tablet as a smartphone. Its battery is 4,050mAh, which should provide solid battery. Unfortunately, it also means the phone weighs a lot.

For comparison, the large Galaxy S7 edge has 5.5-inch display, and it seems diminutive compared to the monstrous phab 2 pro. The Lenovo phone also feels much heavier in hand.

Project Tango isn’t new. Lenovo's hardware is. And what you need to know about the phab 2 pro is that it is HUGE, massive, gigantic. You are not going to want to carry this thing around in a pocket. I know I don't.

So while the concept and the AR tech in the phone are both cool, the execution is a bit off. Lenovo seems to have prioritized the Tango AR experience instead of the overall smartphone experience, and that's just not going to work for the average Joe.
