Latest Microsoft Windows 10 Mobile preview build 10586.71 brings lots of fixes

Microsoft's Windows 10 Mobile test build 10586.71 is a preview of a cumulative update that includes a bunch of bug fixes.

Microsoft is making available to Fast Ring Insider testers another new preview of a cumulative update for Windows 10 Mobile.


Build 10586.71, released February 1, is all about bug fixes. It also includes a Configuration Update that Microsoft also pushed out late last week that was designed to pave the way for future Insider updates.

According to Microsoft, fixes in today's Insider Preview include:

  • Windows Update performance and reliability improvements
  • Improvements in migration of data profiles and messaging settings when upgraded from Windows Phone 8.1
  • SensorCore APIs are now upgraded correctly from Windows Phone 8.1; allowing applications, including many fitness applications, to correctly access movement data
  • SD card detection has been improved on boot and after insertion; File Explorer now handles the removal of an SD card when the default for apps or photos are set to SD
  • Improvements in the Edge browser, including PDF rendering
  • Bluetooth improvements when re-connecting to all ready paired devices and cars; turn by turn directions, and when using Cortana with the Microsoft Band
  • Improvements in Settings when downloading Maps or changing Quick Settings
  • Reinstalling Groove Music from the Windows Store no longer causes DRM music playback issues
  • Groove Music local song collections are now more quickly imported within the application
  • Device power improvements after listening to music, after missed phone calls when iris detection is disabled, and when downloading updates
  • In app purchases now work correctly when cellular data is disabled
  • Improvements to the reliability of Kids Corner

Microsoft officials said recently the company is on track to begin rolling out Windows 10 Mobile to existing Windows Phone 8.1 users in early 2016, as officials said late last year was the plan. There's still no official word on which existing phones will and won't get Windows 10 Mobile.
