Microsoft has unveiled its first phone after completing its takeover of Nokia's handset division - and the device is powered by Android. The operating system, developed by Google, is usually seen as a rival to Microsoft's own Windows Phone OS. Microsoft said the Nokia X2 offered it a way to hook users into its cloud-based services, several of which come pre-installed as apps.
One expert said the alternative would have been leaving "money on the table". "I still find it astounding that Microsoft is making Android phones, but there seems to be a steely determination to take a more open approach for the greater good of the whole company rather than just the Windows Phone platform," said Ben Wood, from the telecoms consultancy CCS Insight.
"If they don't do this, then someone else is going to get the business.
"I also think it's a reflection of the fact that Nokia's budget Asha line of feature phones was unable to compete with entry-level Android mobiles."
Microsoft completed its takeover of Nokia's handset division on 25 April at a cost of 5.4bn euros ($7.4bn; £4.4bn).
· a slightly bigger 4.3in (11cm) screen
· 1GB of RAM - double the amount of memory previously included
· a more powerful battery
· the addition of a front-facing camera for selfies
It will cost 99 euro ($135; £80) when released in July.
Microsoft's video chat app Skype, its Outlook email service and its OneDrive internet storage apps all come pre-loaded.
The firm is also promoting some of its other apps - including Bing Search, the Yammer business-focused social network and the OneNote idea jotting service - as optional free downloads for the device.
"The whole idea of bringing more people into Microsoft Cloud through these services is the very core of the strategy," Jussi Nevanlinna, vice-president of mobile phones product marketing at Microsoft, told the BBC.
