Announcing Windows 10 Mobile Insider Preview Build 10586.122

Hi everyone,

Today we are releasing another Cumulative Update for Windows 10 Mobile Insider Preview Build 10586 to Windows Insiders in the Slow and Release Preview rings: Build 10586.122. This Cumulative Update continues to address feedback we received on Windows 10 Mobile from devices such as the Lumia 950, 950 XL, 550, and 650 as well as the upgrade experience from Windows Phone 8.1. In some cases, improvements and fixes in this Cumulative Update will only be seen when upgrading from Windows Phone 8.1. We are also adding support for 4 additional devices on the Current Branch for Insiders receiving today’s update: MCJ Madosma Q501, BLU Win HD W510U, BLU Win HD LTE X150Q, and ALCATEL ONETOUCH Fierce XL.

Windows Insiders with devices on the Fast ring which are not yet receiving updates from the Development Branch would need to temporarily switch to the Slow or Release Preview rings if they want to receive this build.

If you’re a Windows Insider who is willing to help test the upgrade path that most customers will be taking from Windows Phone 8.1 – you can use the Windows Device Recovery Tool to go back to Windows Phone 8.1 and then download the Windows Insider app from the Store and jump into either the Slow or Release Preview rings to pick up Build 10586.122 for your phone. Please make sure to send feedback on any issues you encounter through the upgrade process or after the upgrade completes. We appreciate Insiders helping us test out the upgrade from Windows Phone 8.1 to help ensure our customers have a great experience.

Here are some of the fixes included in this release:

Give this update a try and as always keep sending your feedback!

Thanks,
