Lisa Gade reviews the Microsoft Surface Duo, a dual screen folding Android phone that’s more innovative and enjoyable than you might expect. The Duo has 360 degree hinges and 2 OLED PixelSense 5.6” 1800 x 1350 displays that can be used individually or open as an 8.1” tablet. You can use 2 apps at a time and flick them front one screen to another, or span both displays. This is the thinnest smartphone on the market at 4.8mm (9.9mm closed). It works with the Surface Pen and Surface Slim pen and uses MPP (aka N-Trig) technology, so the Galaxy Note isn’t the only active pen smartphone option anymore. It has an 11MP camera, 4G LTE, WiFi, Bluetooth 5.0 and a GPS. It runs Android 10 on the Snapdragon 855 and is available with 128 or 256GB storage. It’s compatible with AT&T, T-Mobile (and thus Sprint) and Verizon. Microsoft sells it unlocked and there’s an AT&T locked model. Pricing starts at $1,399, and like Samsung and Apple, Microsoft has a trade in program to help offset the price.
