Microsfot Lumia 640 640XL XL-12

Microsoft has confirmed that its next Windows 10 preview for smartphones will support a significantly greater number of devices. In fact, if you own a Lumia handset, chances are you'll be able to get your hands on it.

Until now, the number of smartphones compatible with Microsoft's Windows 10 preview has been extremely limited. The company explains on its blog that the reason for that is "we had to select from the set of phones that had sufficient system partition sizes configured by the manufacturer."

But thanks to a new "partition stitching" feature, Microsoft can now support a greater number of devices, which in turn will provide greater feedback from users regarding Windows 10 bugs and others issues.

"This testing will allow us to support A LOT more phones for the next flight," writes Microsoft's Gabe Aul. "I get a ton of questions every day on Twitter about when your favorite phones will be usable, and I'm happy to report that the vast majority will be supported with the next flight (full list below.)"

Unfortunately, that "vast majority" consists of Lumia-branded devices only, so those with Windows Phone handsets made by HTC, Samsung, or LG are still out of luck for now. But here's the preliminary list of handsets that'll be supported by the next preview:

  • Lumia 1020
  • Lumia 1320
  • Lumia 1520
  • Lumia 520
  • Lumia 525
  • Lumia 526
  • Lumia 530
  • Lumia 530 Dual Sim
  • Lumia 535
  • Lumia 620
  • Lumia 625
  • Lumia 630
  • Lumia 630 Dual Sim
  • Lumia 635
  • Lumia 636
  • Lumia 638
  • Lumia 720
  • Lumia 730
  • Lumia 730 Dual SIM
  • Lumia 735
  • Lumia 810
  • Lumia 820
  • Lumia 822
  • Lumia 830
  • Lumia 920
  • Lumia 925
  • Lumia 928
  • Lumia ICON
  • Microsoft Lumia 430
  • Microsoft Lumia 435
  • Microsoft Lumia 435 Dual SIM
  • Microsoft Lumia 435 Dual SIM DTV
  • Microsoft Lumia 532
  • Microsoft Lumia 532 Dual SIM
  • Microsoft Lumia 640 Dual SIM
  • Microsoft Lumia 535 Dual SIM

A notable absentee is the Lumia 930, but most of Microsoft's most popular devices are there. Just because your handset is on this list, however, does not mean you should upgrade to Windows 10 as soon as it's available.

These preview releases are intended for testing only, and certainly aren't intended to power daily drivers. They still have bugs and numerous features are broken, such as full dual-SIM support, voice notes and drafts in Messaging, and Internet tethering.

Unless you have a spare Lumia handset, you should avoid Windows 10 for now, then. Microsoft has promised the stable, public release will be available this summer.
