Microsoft released the first Windows 10 build for Phones on 12th of Feb and thereafter it has been a lull period without any follow-up update. Now the first build was only available for select few devices due to what Microsoft calls a Partioning Issue.
On 27th March, Microsoft via a blog post revealed that its next build of Windows 10 for Phones is almost ready and it will be released to not one, not two but 36 Lumia devices. Thats quite a significant jump considering that the first build was only available for 6 Lumia devices.
Microsoft expects to unveil the build in question here within a period of 7 to 10 days. So in all likelihood, we would be looking at the build by 5th Mar or in the worst case by 7th or 10th Mar.
Heres the list of Lumia devices which will be getting the next build of Windows 10. There is only one condition here, if Microsoft encounters any device specific bug during the final testing then that device will be removed from the below list.
- 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
Yes Lumia 930 & Lumia 521 are missing from the above list but thats due to some device specific bugs encountered. If MS is able to resolve those bugs before the release of next build then these devices may also get included.
Here it is right from Microsoft
Hi everyone,
When we sent out the first build of Windows 10 Technical Preview for phones on February 12th, the list of phones was very limited. 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.
Also in the last month we heard feedback on build frequency, and adjusted how we are sending builds out as a result. The latest build for PCs is the first build that we’ve delivered on that new cadence. We expect the same principles to hold for phones as well as PCs, but the first step for us was to get partition stitching done so that we could unlock a much larger set of phones for you to use for Windows 10 technical previews.
Here’s a quick update on where we are:
- The partition stitching feature code came into our main code branch late last week. The Storage and Filesystems Team had been working on this in their branch and it passed all of their quality evaluations.
- We spent this week testing on individual devices, as well as providing the builds with this feature to our internal rings so that we all could test it on our own phones which had been previously not usable. I’ve been thrilled to get my beloved Lumia 1020 on Windows 10!
- This testing will allow us to support A LOT more phones for the next flight. 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.
- We’ll also have support for phones that didn’t have China Mobile Operator support in the last build, so that’s great news too for our Windows Insiders in China.
- We still have some work to do to validate individual phones, as well as the builds that we’re flighting through our internal rings. As I said in the post on frequency I cannot guarantee a date for a new build. What I CAN tell you is that we feel great here about the partition stitching code and current builds, but we likely still have at least one more week of engineering to do to ensure we get a great build for the expanded list of devices.
