Microsoft wants Feedback on Upgrading to Windows 10 Mobile 10586.122 from Windows Phone 8.1

It looks like we are getting closer to a proper public release of Windows 10 Mobile as Microsoft is looking for more feedback from Windows Phone 8.1 users upgrading to Insiders build. The current version rolling out is 10586.22 and Microsoft has deliberately asking people to revert to Windows  Phone 8.1, and the upgrade here to see how much improvement can be noticed.

Microsoft has also included 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.

If you are up, and ready to test it from Windows Phone 8.1, you will need to use the Microsoft Device Recovery Tool to revert to Windows Phone 8.1, and then install Windows Insider to select one of the preview builds. Sending Feedback is important so they know if this build is good enough for public release.

What is interesting to note here is that 10586.122 is being pushed out to both Slow, and Release preview rings as well. This is rare, and points to the fact that this could become the first public release for Windows Phone 8.1 devices. May be we are like 2-3 weeks away from getting a public release.

Here are the fixes included in this release:

• Updated background processing of multiple changes to improve battery life of devices.
• Improved overall OS reliability, including reliability of the Start screen, app updates, and the Windows Feedback app
• Improved Kanji input experience while using Continuum.
• Improved the speed in which thumbnails appear for portrait videos.
• Improved Internet Sharing on select mobile network configurations.
• Fixed an issue in Microsoft Edge that prevented Word Flow input on some sites.
• Fixed an issue that previously prevented the option to “Close all Tabs” in Microsoft Edge from closing all open tabs.
• Improved IMS registration on select mobile network configurations.
• Fixed an issue where adding your MSA during OOBE would fail and prevent the account from being re-added after the failure.
• Improved the email sync experiences when connecting to Wi-Fi networks with a captive portal.
• Improved data connection profiles for dual SIM devices.
• Improved quality of video record to SD memory cards.
• Improved video recording audio in some cases.
• Improved Alarm reliability.
