Microsoft's next test version of Windows 10 Mobile, expected around the first week of April, will support a lot more devices than the first one did.

Microsoft's Operating Systems Group team has added code to the next test build of Windows 10 Mobile that will allow that release to work on the majority of Windows Phones.
When Microsoft released the first test build of Windows 10 Mobile in February, it was built to run only on a handful of Lumia devices, specifically the Lumia 630, 635, 636, 638, 730 and 830 phones. Microsoft execs attributed the small number of initially supported devices to the "very tight OS partitions" that left insufficient room for the installation process to update the OS in place.
The aim of the test builds is to elicit comments, questions and complaints from Windows users, looking at those preview versions of the upcoming operating system, that could help Microsoft fashion a Windows 10 that will have a broader appeal than its predecessor, Windows 8. Windows 10 is intended to run across a wide range of devices, from desktops and laptops to smartphones and more industrial devices.
The initial list of Windows Phones, which isn't 100 percent locked, according to the post, includes these devices:
The head of Microsoft's Windows Insider program, Gabe Aul, said that the required partition-stitching feature code required to support these phones came into Microsoft's main code branch late last week. Last week, Microsoft tested that code on individual devices inside the company. Aul also said the next test build will include support for phones that didn't have China Mobile operator support in the first test build.
