Microsoft Delivers Windows 10 Mobile Insider Preview Build 10581

The happy surprises just keep on coming: Microsoft today delivered build 10581 of Windows 10 Mobile to Windows Insiders on the Fast ring. This is the third Windows 10 Mobile build we’ve seen in as many weeks.

Here’s what’s new.

Build-over-build upgrades are fixed. “We’ve fixed the bug preventing upgrades from earlier builds,” Gabe Aul writes. “So if you stayed on Build 10536 or if you flashed back to Windows Phone 8.1 and then installed 10549 or 10572 you can upgrade directly to this new build without going back to 8.1 again.”

No significant new features. Normally, that would be disappointing, but this could indicate that initial Windows 10 Mobile development is wrapping up. We are getting pretty close to the deadline, after all.

Fixes. Microsoft has fixed a number of issues with this build. Photo sharing with third party apps works again. “Hey Cortana” works on the Lumia 930, Lumia Icon, and Lumia 1520 again. Battery life has been improved. Visual Voicemail sync works again. Dual-SIM issues in build 10572 have been fixed. And so on.

Known issues. Software may be magic, but it’s not perfect: Build 10581 could trigger a 5 minute blank screen on upgrading, so don’t freak out. Default save locations cannot be changed, though it will respect whatever you had configured before the upgrade. Some apps might crash if moved to an SD card, but if you reboot they’ll be fine.
