Microsoft’s bringing the Surface Duo to market Sept. 10, with preorders starting Wednesday. The $1,399 Surface Duo, powered by a modified version of Google’s Android software, puts a different spin on the foldable phone trend, joining Samsung’s recently announced , the and last year’s reboot. is the key difference, bringing together two 5.6-inch screens instead of relying on one massive display that can be folded. Microsoft created the Surface Duo over five years, developing the hinge in a way that’s easy to open but hard to accidentally close. The hinge allows the super-thin screens to rotate 360 degrees. , per se. Instead, it wants us to think of this as a new type of product.
“When we designed it, the intent was, ‘How do you make something so thin, beautiful, light and super elegant that when people pick it up they can feel that emotion in the product,” Panos Panay, Microsoft’s chief product officer and head of Surface devices, said in an exclusive interview.
The device brings new ideas to the mobile world, including software Microsoft wrote to make the two screens interact. You can drag a photo from one screen to the other and it works thanks to a mix of computer programming that follows your finger across the screens. There’s also an array of sensors that track where the displays are relative to each other, including if they’re open, closed or somewhere in between.
While CNET editor at large Scott Stein — a noted dual-screen skeptic — says the device felt good in his hands, he says $1,399 is a lot of money to ask of people on a normal day, let alone in the middle of an economic downturn fueled by the .
Still, Microsoft invited us to talk with its engineers about how the Surface Duo was conceived, the technology invented to make it possible and how it’ll work when we get it in the mail (watch out for CNET’s review in the next few weeks).
In, Stein shares what it was like to hold a Surface Duo prototype. Microsoft shipped us a near-production prototype device with the screens replaced by clear glass so we can see the inner working and learn how it works. Stein also talks about why he hasn’t like dual-screen devices before, and why the Surface Duo may be the device to change his mind.
In, we look at where the Surface Duo fits in the world, and why Microsoft is choosing to make a new handheld device after a series of embarrassing multi-billion-dollar attempts that ended in failure.

Here’s what else you need to know about the Surface Duo.
How much will the Surface Duo cost?
Microsoft is charging $1,399 for the 128GB version of the Surface Duo. There will be a 256GB version as well.
Will the Surface Duo have 5G?
Nearly every major phone launch this year, including 5G wireless capabilities. Samsung’s , announced earlier this month for $1,300, has 5G. So does its cousin, the , whose price and launch date will be announced in September., is expected to support
The Surface Duo, on the other hand, will work with 4G networks. Microsoft said the reason comes down to tradeoffs — the company chose to stick with the previous generation wireless tech to allow for better battery life and a thinner device.
Where will it sell?
Microsoft AT&T and Best Buy, too., so you won’t be able to find them there even if you’re willing to venture out during the pandemic. It will be sold online through Microsoft’s website. You’ll be able to buy it from
If the $1,399 starting price is too steep for you, Microsoft said it’ll offer a 0%, 24-month payment plan through Dell financing. AT&T similarly will allow you to pay in installments through its Next Up program.
How well do apps run in the phone?
Microsoft made a point of showing us that standard Android apps run on the device just fine, thanks to its two screens being the equivalent of two standard phone displays. For apps built with the second screen in mind, they can be designed to “span” across the two screens, meaning an email app could have your inbox on the left and opened messages on the right. They could also be programmed to open new links or companion apps in the opposite screen you’re looking at.
Microsoft demonstrated Amazon’s Kindle book reading app, which was designed to look like a book with text on the left and right. When you swipe your finger across the screen, an animated page follows along.
At launch, it appears Microsoft’s apps will primarily be the ones built with the Surface Duo in mind. Those include Microsoft Office, Outlook, Teams, OneNote and Authenticator. Oh, and you can’t forget Microsoft Solitaire Collection too.
The company said that it’s working with Google to integrate some of the software it developed for the Surface Duo back into Android so other two-screen devices in the future will benefit from Microsoft’s work. That also means more apps may eventually be programmed for the Surface Duo as a result.
How many folds can it take?
We’ve tested a few folding devices at CNET using a special robot developed by SquareTrade. The phones and that could change with the different designs companies are inventing).began failing after about 120,000 folds during our test last year. That was much less than the 200,000 folds we estimated it would go through during five years of use. (Although we’re just starting to learn how people use folding
When we put the new Motorla Razr through FoldBot’s paces last year, that device.
Microsoft preemptively said folding test robots don’t simulate real life usage the same way its own labs do. Still, it wouldn’t say how many folds the Surface Duo could last through, except that the company expects the hinge mechanism to last beyond the Surface Duo’s own natural lifecycle.
Will I be able to take sweet shots with the camera?
Many companies releasing premium phones justify their $1,000 or more prices with the beautiful photographs they say you could take. Apple has thatbillboard campaign, and the . Samsung boasts about how its devices can deliver with their cameras. And Google proudly says its advanced programming makes photos on its Pixel phones unlike competitors, offering shockingly well . They can even photograph .
By comparison, Microsoft’s mostly talked about how the Surface Duo is built for productivity and better interaction between apps. Translation: Its camera will not be a killer feature.
CNET will still test the camera against other premium phones when we do our reviews.
Will it get quick Android updates?
One of the most vexing parts of owning a phone powered by Google’s Android software is Android itself. Manufacturers routinely fail to deliver timely updates to users, even with Googlemonths ahead of the typical fall release.
Microsoft says it’s working with Google directly on the Surface Duo, which naturally led to questions about whether that means it’ll get updated more often and more quickly. Microsoft says the device will get software updates, but didn’t commit to timetables about when.
Other details about the Surface Duo
- A 360-degree hinge means you can fold one screen flat against the other to hold it like a notepad.
- You get a total of 8.3 inches of screen real estate.
- There’s no outer screen — you have to open the device to use it.
- It supports the Surface Pen, which you need to buy separately for at least $99.
- The Surface Duo has thick screen bezels, but that might help keep you from accidentally tapping while you hold it. Microsoft said the bezels are a tradeoff from miniaturizing parts and making the screens so thin. It’s also Microsoft’s way of saying smaller bezels are likely in the future.
- You can drag and drop items, like a phone number, from one screen to the other.
