The Surface Duo extends Microsoft’s popular Surface product line to an Android-powered dual-screen phone aimed at business users. Designed for mobile business productivity, the foldable phone with two displays combines the Surface computer’s fast Microsoft 365 apps with the power of Android, and productive video calls. The Surface Duo is essentially a portable version of the Surface computer, but for business people on the go.

The Surface Duo is Microsoft’s thinnest Surface with a 360-degree hinge. The screen is 8.1 inches wide measured diagonally across the two screens that are connected together by the two hinges. This flexibility allows users to operate the Duo like an e-reader, or flip over one of the screens into a tent shape to watch content on a flat surface, or just for use like a regular smartphone. It can also be used like a miniature Surface laptop with its touchscreen keyboard.

The extra screen size, without being too large, lets users type notes, letters and send texts on a larger keyboard. Artists can also draw and write on the screen, while anyone will be able to easily make video calls from the Duo just like they would with any other smartphone.
