Microsoft Surface Duo review - Prototype first, product second - Android

The Surface Duo explores a new form factor in mobile computing, but in the process creates more problems than benefits.

Microsoft’s new “foldable” phone — the Surface Duo — is certainly different. While most of the foldable market has been defined by flexible devices that can seamlessly transition from small to big or vice versa, Microsoft believes in breaking your focus into two distinct windows.

The Surface Duo is a dual-screen device more than a foldable one, though it does fold almost perfectly in half when closed, leaving a clean booklet of hardware that is an impressive feat of engineering.

But what are the use cases for a dual-screen device? Are two separate displays as useful as one expandable one? And, more importantly, was Microsoft able to nail the smartphone nearly four years after the death of Windows Phone?

Find out in Android Authority’s Microsoft Surface Duo review.

Microsoft Duo Only for enthusiasts
Microsoft's Surface Duo tries to take the road less traveled for foldable devices, but its buggy software and niche use cases mean it's not yet ready for the mainstream.

About this Microsoft Surface Duo review: I used a Microsoft Surface Duo review unit supplied by the manufacturer over 12 days. It was running build number 2020.812.86, based on Android 10. The device received a software update for stability and performance improvements seven days into the review period.

  • Open: 145.2 x 186.9 x 4.8mm
  • Closed: 145.2 x 93.3 x 9.9mm
  • 250g
  • Closing booklet design
  • Fingerprint reader
  • 360-degree hinge

The Microsoft Surface Duo’s design can be compared to a small booklet like a passport. Closed, it is only slightly thicker than the Samsung Galaxy Note 20 Ultra — 9.9mm compared to the Note 20 Ultra’s 8.1mm (which doesn’t consider the Note’s comically large camera bump.) Opened up, it’s about half as thick as closed at just 4.8mm. It’s barely thicker than the USB-C port used to charge the device.

That’s a pretty massive feat of engineering. While most phones aren’t inherently too thick for use, Microsoft wanted to make sure the Duo’s footprint was as close to a standard device as possible when closed. A primary criticism of foldable phones is the fact that they’re often about as thick as two phones, but the Surface Duo challenges that notion.
