Windows 10 Mobile Insider Preview build 15210 now available in the Fast ring

Last Friday, Microsoft released Windows 10 Mobile Insider Preview, build 15208, to the Fast ring. Today, it's following up with a further release, build 15210 - but there's not much to get excited about.

15210 is the fifth build to emerge from the Windows 10 Mobile 'feature2' branch, which Microsoft recently split from the main Windows 10 Redstone 3 (RS3) Development Branch, which will eventually lead to the next major update to the OS in September. The latest PC preview, build 16188, was also released from the RS3 branch today, and includes a range of new features - but the list of changes for the new Windows 10 Mobile preview is much shorter.

These are the fixes in Mobile build 15210:

  • We fixed an issue with the Glance screen where the time was not updating.
  • We fixed the token issue so when your device syncs to the service, text messages should show back up.

And here are the known issues:

  • The copyright date is incorrect under Settings > System > About. It shows as 2016 when it should be 2017. Thanks to the Windows Insiders that reported this!
  • In some cases, the WeChat app may crash on launch.

Both of those issues were present in build 15208 last week, but two other problems - including random shutdowns on some devices - have since been resolved.
