UPDATE: We’re seeing that some small percentage ~0.1% of eligible Mobile devices, including variants of the Alcatel IDOL 4S, are not being offered Build 15204. We’re working on updating the targeting to include them for the next flight.

Devices not on this list will not officially receive the Windows 10 Creators Update nor will they receive any future builds from our Development Branch that we release as part of the Windows Insider Program. However, Windows Insiders who have devices not on this list can still keep these devices on the Windows 10 Creators Update at their own risk knowing that it’s unsupported.

We recognize that many Insiders will be disappointed to see their device is no longer supported. We looked at feedback from our Windows Insiders and realized that we were not providing the best possible experience for our customers on many older devices. That helped us determine which devices we support for the Windows 10 Creators Update. We are continually listening to your feedback to provide the best experience for ALL of our customers.

For developers – you will need to set the minimum platform version in Visual Studio to be the Windows 10 Creators Update.
