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.

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

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...
