First widely available Tango phone ; Reasonably priced for bleeding-edge tech ; Excellent battery life if you don't use Tango ; Reassuring build quality ; Fingerprint sensor works well

Tango is still a work in progress ; Huge size could be a deal-breaker ; Cameras are pretty lousy ; Lenovo's software is rough around the edges

The Lenovo Phab 2 Pro is an incredible thing, and it's just brimming with potential. It's also unpolished and frustrating to use a lot of the time. When the hardware and software don't come together as they should, it makes me wish Google and Lenovo...

Tango is fun when it works ; Interactive app experience ; No headset required for AR

Massive smartphone ; Tango is still half-baked ; Too few Tango apps right now

It’s a 3D world; we’re just living in it

Good value ; Near-stock Android Marshmallow ; Tango is fun to try and show off...

...but it loses its luster quickly ; Awkwardly-placed fingerprint sensor ; The large smartphone, redefined

The Phab 2 Pro is a strong effort and value on its own, made sweeter by the Tango AR. Your mileage may vary with Google’s experimental tech, but it's undeniably ripe with potential and novelty.

First phone with Google Tango. Crisp Quad HD display. Fingerprint sensor, dual SIM, expandable storage, and dual-band Wi-Fi support.

Huge. Most Tango apps feel unpolished and lack compelling functionality. Subpar camera performance.

The colossal Lenovo 2 Pro is the biggest phablet we've reviewed in years, and one of the most unique. For $500 you get a crisp Quad HD display, promising AR functionality with Google Tango, and a premium build. But Tango still has some ways to go...

Good, high-resolution display ; High-capacity battery with excellent screen-on times ; Runs available Tango apps well

Will be much too big for many people ; Heavy, bulky, and slippery design makes drops more likely ; Middle-of-the-road hardware means shorter lifespan

All of this begs the question: is the Phab 2 Pro worth it? Considering the hardware the phone offers and the current state of Tango, I’d only say it is if you’re the kind of person who wants to be right there at the starting line as a new technology...

dual-SIM with support for U.S. GSM 4G bands ; well-made and rigid aluminum chassis ; generally cool surface temperatures ; fast-charging Micro-USB port ; great speakerphone quality ; large 6.4-inch QHD display ; fast CPU performance ; integrated Tango

non-removable battery; average battery life ; awkward positioning of fingerprint reader ; no NFC, USB Type-C, or wireless charging ; display colors could be more accurate ; large and heavy; over 10 mm thick ; average display response times ; average...

The big selling point of the Phab 2 Pro is its unique Tango hardware. At its current state, however, the feature is more of a novelty than it is a practical implementation. Aside from its gaming potential, Lenovo has promised the ability to navigate...

Premium-ish build quality ; Great display for your cash ; Cutting edge tech at a (relatively) mid-tier price

Mid-range CPU is cutting it too close for AR ; Bulky and awkward to hold ; Camera autofocus needs improvement

A low-cost, low-risk way to try out AR, but you need to put up with the compromises
