Definition: Surface Duo


A dual-screen Android phone-tablet from Microsoft. Introduced in 2020 and discontinued in 2023. The Surface Duo comprised two 5.6" screens hinged together that opened originally to an 8.1" tablet-size display and later 8.3" with the Surface Duo 2. The Duo supported Microsoft's Surface Pen and made phone calls like a smartphone.

Multiple apps or just one app that spanned both screens could be displayed. For example, while viewing the image library on one screen, users could see the selected photo on the other. The Surface Duo ran Microsoft 365 and all Android apps on Google Play. See Surface versions and Surface Pen.
