Microsoft has long been rumoured to be working on its own smartphone - the Surface Phone - destined to run the company's Windows 10 operating system.

While leaks were plentiful a couple of years ago, with reports suggesting the device had been "green lit" and was being worked on by the Surface tablet team, things have been quiet more recently. This is everything we know so far about Microsoft's Surface Phone. 

Release date and price

  • May 2016 first suggested
  • April 2017 then claimed
  • 2019 and still no word

It was first rumoured that Microsoft was aiming for a May 2016 release for its Surface Phone, though this date then moved to April 2017 after a report from Windows Central claimed the company was planning to launch a Redstone 2 update with new hardware in April 2017.

Of course, we are several years past April 2017 now and there is still no sign of a Microsoft Surface Phone, or much to suggest it is coming soon.

In terms of price, if the Microsoft Surface Phone ever does appear, we'd expect a premium price tag like the Surface tablets.

The Surface Phone, codenamed Januss, is said to have three screens, two on the inside of a foldable body and one on the outside so it can still be used when it's folded shut.
