In a blog post from Microsoft, the company says the next build of the Windows 10 Technical Preview for phones will hit a lot more devices. In addition to a massively expanded list of supported devices, the blog post notes that Microsoft is looking to increase the frequency at which Windows 10builds will be released for phones. The increase in frequency for Windows 10 releases for phones follows a similar path that Microsoft recently laid out for desktop builds. On the topic of the rollout to more phones, the blog post reiterates that the previous limited rollout was due to a partition size issue: "As I wrote in the accompanying blog post, the reason for this is that we had to select from the set of phones that had sufficient system partition sizes configured by the manufacturer. This was necessary for us to be able to in-place upgrade the phones. I also talked about a feature we were working on called "partition stitching" that would allow us to re-size the system partition dynamically, allowing us to do the upgrade on a larger set of phones." And Microsoft isn't joking about that larger number of phones. Without further ado, here's the full list of phones that are expected to be eligible for the next build of the Windows 10 Technical Preview for phones: 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 The blog post doesn't detail when the build will be available, but it does note that Microsoft likely hasat leastone more week of testing to go. In any event, this is great news for those that have been patiently awaiting another build, let alone the massive increase in supported devices.
