Microsoft Ships Windows 10 Mobile for Phones Build 10166

Following yesterday’s release of Windows 10 build 10166 for PCs and tablets, Microsoft today release Windows 10 Mobile build 10166 for phones. Like the PC build, this one is for Fast Ring testers only. So you can upgrade from a previous build or from Windows Phone 8.1 to get it.

Curiously, Microsoft doesn’t have a lot to say about this build. As you must know, Windows 10 Mobile is lagging behind Windows 10 for PCs and tablets by some months, so we should be seeing lots of updates apps and features with each new mobile build. Instead, Microsoft says that it “major focus over the past few builds on mobile has been about improvements to core quality.” So there are only a few changes noted:

Previous issues fixed. Most of the known issues Microsoft listed for Build 10149 have been fixed. The company also fixed the issue where the post-upgrade migration status screen was missing, which could make the lock screen appear frozen without the date and time for up to 10 minutes. Microsoft also fixed the issue where you were unable to unlock your phone after entering your PIN and it keeps letting you type even though you entered your pin correctly that was caused by a TPM issue.

App colors are correct. The colors in apps should now appear correctly. This includes the title bar in the Outlook Mail app, which was previously (and incorrectly) orange.

App download and update reliability. Microsoft says it has improved the reliability of app downloads and updates from the Store app, which loses the “Beta” tag in this release. Also, the old Store app is no longer in the build.

Battery icon. The battery icon has been made bigger based on feedback about its small size.

App updates. Microsoft recommends that testers check the Store for the latest app updates after upgrading the OS, noting that there have been “lots of improvements to apps over the past few weeks as well.”
