The Microsoft Surface Duo is Microsoft's first dual-screen Android phone, built around two 5.6-inch displays joined by a 360-degree hinge that opens flat into an 8.1-inch reading and multitasking surface. It shipped for people who wanted a pocketable device that could run two apps side by side, take notes with a pen, or fold away into something thinner than most single-screen flagships. There's no separate numbered model line here, just the original Surface Duo, sold in 128GB and 256GB storage tiers. Because it was a limited-run, first-generation device, working units in good condition still draw interest from collectors and Android tinkerers, which keeps resale demand steadier than you'd expect for a discontinued phone. Pick your storage configuration and condition above for an instant cash offer, or see how the process works before you send it in. When you're ready, you can also start the listing to sell your Microsoft device directly.
Confirm you have the Surface Duo
The fastest way to confirm your exact configuration is on the device itself. Open Settings → System → About phone and check the storage capacity listed under internal storage, along with the Android version and build number. There's no external screen or badge that states the storage tier, so the settings menu is the only reliable source once the unit is powered on.
128GB configuration
- Entry storage tier
- Confirmed via Settings → System → About phone
- No expandable storage slot
256GB configuration
- Higher storage tier
- Same processor and display hardware as the 128GB model
- Generally holds slightly higher resale value
Prefer a visual check? Look for the 360-degree book-style hinge with two separate 5.6-inch panels, a single rear camera housed in the top bezel of one screen (there's no second camera module), and the Microsoft logo etched into the hinge cover.

Display & audio
Two 5.6-inch AMOLED panels joined by a 360-degree hinge, giving an 8.1-inch combined workspace when unfolded flat. Each panel functions independently or as one extended canvas depending on the app.
A single speaker handles audio output, and there's no 3.5mm headphone jack, so wired listening requires a USB-C adapter or headset.
Security runs through a fingerprint sensor built into the power button, used for unlocking and app authentication instead of face recognition.
Ports & connectivity
The Surface Duo keeps its physical connections minimal, which fits its thin, book-like design.
- USB-C (charging and data)
- No headphone jack
- 4G LTE (no 5G on this generation)
- Wi-Fi
- Bluetooth
- NFC for contactless payments

Battery, build & more
Two battery cells, one in each half of the hinge, are managed as a single combined battery by the software. There's no wireless charging.
Finishes were limited to Glacier (a light finish) and Obsidian (black), both with a glass front and rear on each screen half.
Runs Android with Microsoft's dual-screen software layer on top, including span mode for running one app across both displays.
Known issues include a hinge gap that collects lint and dust over time, no official water or dust resistance rating, and a single-camera design that some buyers find limiting compared to phones with multiple rear lenses.
