Microsoft has just released the Windows 10 Mobile Build 10586.122 for the insiders enrolled in the slow and release preview rings. It’s part of a cumulative update and aims to bring Windows 10 Mobile in line with Windows 10 for PCs, which received the same number build yesterday.

Microsoft releases Windows 10 Mobile Build 10586.122

Gabe Aul, head of the insider program said that this new build is particularly focused on feedback received from new Lumia devices that shipped with Windows 10, namely Lumia 950, 950 XL, 550, and 650. It’s also supposed to improve the transition from Windows Phone 8.1, which could be a sign that Microsoft’s working to bring the upgrade version to the market in the coming weeks.

Also, Four more devices were added to the insiders program with this build release for the current branch: MCJ Madosma Q501, BLU Win HD W510U, BLU Win HD LTE X150Q, and ALCATEL ONETOUCH Fierce XL.

As far as this build is concerned, it contains several fixes and improvement with no known bugs. Following are the important highlights of Windows 10 Mobile Build 10586.122.

  • Improved the speed in which thumbnails appear for portrait videos.
  • 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 quality of video record to SD memory cards.
  • Improved overall OS reliability, including reliability of the Start screen, app updates, and the Windows Feedback app
  • Updated background processing of multiple changes to improve battery life of devices.
  • Improved Kanji input experience while using Continuum.
  • Improved data connection profiles for dual SIM devices.
  • Improved video recording audio in some cases.
  • Improved Alarm reliability.

For the Fast ring members, there is work to be done. They first need to switch back to Windows 8.1 using WDRT and then upgrade to Windows 10 Mobile as Gabe Aul pointed out. It’s a lot of work and time consuming process which we think is not everyone’s cup of tea.
