You might not consider the Surface Duo to be in the same category as Sammy’s foldable but Microsoft does. The Duo doesn’t have a flexible display like the Galaxy Z Fold 2 does but instead relies on two displays and a revolutionary 360-degree hinge; the latter could allow a user to form a 90-degree angle between the two displays allowing the Duo to be used as a mini laptop. Or with the two screens configured as an inverted “V,” the Duo could be placed on a night table and used as an alarm clock.

The Surface Duo comes with a pair of 5.6-inch AMOLED displays that open up to form a tablet-sized 8.3-inch screen with that aforementioned hinge in the middle. The Snapdragon 855 Mobile Platform, Qualcomm’s 2019 flagship chip, will be under the hood along with 6GB of memory and storage options of 64GB, 128GB, and 256GB. A single 11MP camera is onboard and the lights are kept on thanks to a 3460mAh capacity battery.

Google has been working with Microsoft to optimize its apps for the dual screens. While some had hoped that the software giant would bring back the Windows Phone operating system, the so-called “app gap” was just to much to overcome. This refers to the paucity of popular apps that were available to Windows Phone users back in the day. It was a vicious cycle really. Developers refused to build a Windows Phone version of their apps because of the operating system’s microscopic market share of the smartphone market. But not having those apps available is what helped Windows Phone achieve those low market share figures in the first place. In addition, Microsoft happens to own some patents related to Android; even during the best of times the company made more money from those patents than it ever did selling handsets powered by Windows Phone.
