Microsoft Addresses Stability Issues With Windows 10 Technical Preview Build 10052 For Phones

We reported last week that Windows 10 Build 10051 for smartphones, the first release to bring the Spartan web browser to mobile users, was causing some issues for Lumia 520, 525, and 526 users. Users encountered problems when attempting to rollback their Windows 10 install to Windows 8.1 using Microsoft’s Windows Phone Recovery Tool (WPRT).

Microsoft took prompt action and pulled Build 10051 for the affected Lumia phone users and updated its WPRT to address the problem. The Redmond, Washington-based software giant is taking a further step today by releasing an incremental update, bringing us to Windows 10 Build 10052.


Just a single number separates this latest build from the one released 11 days ago, so no new features additions are bring brought to the table. However, Microsoft has addressed the following nagging issues with Build 10052:

  • Flight mode can now be enabled.
  • You can now disable data connections.
  • We fixed the bug in which your phone’s MMS settings were lost after upgrading from Build 9941.
  • We fixed the issue in which you couldn’t download keyboards for additional languages.
  • We fixed the issue where the viewfinder in the Camera app gets composed incorrectly on some devices like the Lumia 1020.

Seeing as how the issue with rolling back installations on the Lumia 520/525/526 has been resolved, Microsoft is now allowing those smartphones to upgrade to Windows 10 Build 10052.

We can expect to see a much bigger update for Windows 10 at the end of April. At that time, Microsoft will release a new build with support for Office Universal Apps.
