If Microsoft has yet to share a date for the release of the Windows 10 Mobile Fall Creators Update, the company has now revealed the list of eligible devices on a support page. And unfortunately for Lumia 640 and 640XL owners, it looks like both handsets are not officially supported (via Windows Central) .
Here is what Microsoft is saying on the Windows 10 Mobile support page, and you can see that both the Lumia 640 and 640XL are missing from the list:
The Windows 10 Fall Creators Update (1709) is only available for the following Windows 10 Mobile devices, and availability may vary by carrier and market:
HP Elite x3, HP Elite x3 (Verizon), HP Elite x3 (Telstra), Wileyfox Pro, Microsoft Lumia 550, Microsoft Lumia 650, Microsoft Lumia 950/950 XL, Alcatel IDOL 4S, Alcatel IDOL 4S Pro, Alcatel OneTouch Fierce XL, Softbank 503LV, VAIO Phone Biz, MouseComputer MADOSMA Q601, Trinity NuAns Neo.
Earlier this year, Microsoft announced that old Nokia Lumia phones such as the Lumia 730, 735, 830, 930 and 1520 wouldn’t receive the Creators Update. However, owner of these handsets could still install the update by joining the Windows Insider Program and the Release Preview ring, though doing this would leave these handsets in an unsupported state. This time, Microsoft may well do the same for the Lumia 640 and 640XL: if you own one of these, you can still install the Fall Creators Update (the “feature2” build 15252, to be precise) on your handset by joining either the Slow or Fast Ring, though Microsoft may well close that loophole at some point.
The Lumia 640 and 640XL were announced back in March 2015, and these first "Microsoft" Lumias were marketed by the company as Windows 10-ready. Considering that both handsets can run the build 15252 just fine (the “Fall Creators Update” for mobile just brings a couple of fixes and very few new features anyway), this decision may seem a bit unfair. However, both handsets are almost three years old now, which is pretty much an eternity in the tech world. We’ll see if Microsoft clarifies the fate of the Lumia 640 and 640XL over the coming days, but you may want to join the Windows Insider program as soon as possible if you really want to get the Fall Creators Update.
