Windows 10 Mobile build 10572 now available for download

Here's what's new in the latest preview of Windows 10 Mobile (build 10572), and once again Microsoft advices users to roll back to Windows Phone 8.1 before upgrading due to a bug.

Microsoft has just pushed Windows 10 Mobile build 10572 to the Fast ring of updates. The new preview for mobile devices includes a number of improvements and fixes over build 10549, which the company released only a week ago.

Head of the Windows Insider program, Gabriel Aul announced on October 20th that the team is ready to ship a new build of the operating system for phones. However, just like with previous releases, build 10572 includes a bug that blocks users on the current preview to install the next version. As such, users must roll back to Windows Phone 8.1 in order to install Windows 10 Mobile build 10572.

Microsoft recommends to use the Windows Device Recovery Tool to go back to Windows Phone 8.1, then install the Windows Insider app, choose the Fast ring option, and restart your phone. Only then, users will be able to download and install build 10572.

It’s important to note that Microsoft also said that it has fixed the upgrade bug, but it will be available on Windows 10 Mobile build 10575 and later — though, this doesn’t mean build 10575 is the next preview the company will release to Insiders.

Here’s what’s new in Windows 10 Mobile build 10549

Cortana: Starting build 10572, Cortana will send notifications to your PC “(needs to be running Build 10565 or higher) when you missed a call. When you miss a call, you can reply with a text to the person who called you right from your PC and Cortana will have your phone send it.”

Missed call notification

If you want to send a text from your PC at any time (even when you haven’t missed a call), “type or speak “Text” and the name of a contact to Cortana on your PC in the same way you would on your phone and Cortana will take your message and send it from your phone.”

Remember that to make the new feature work, you need to be signed with your same Microsoft Account in your phone and on your PC. “If you have multiple PCs and don’t want to receive missed call notifications on one of those PCs, you can go to Cortana’s Notebook and then to Settings to toggle “Missed call notifications” to off on any PC on which you don’t want to receive these notifications.”

If you don’t want your phone to send any notifications, “go to Cortana’s Notebook and then to Settings to toggle “Missed call notifications” to off and the phone won’t send the notification to any of your PCs.”

Similar to Windows 10 build 10565 for PC, in build 10572 for mobile devices, “Cortana can help keep track of your leisure time, including movie and event reminders and will give you helpful information to know where to go and to get there on time, including an option to book and track an Uber ride directly from Cortana.” […] “You can book an Uber any time you want by saying ‘Book an Uber’”.

Skype messaging, calling and video experience: This build has the “Skype integration through the Messaging, Phone and Skype video universal Windows apps. Additionally, the Messaging app now supports animated GIFs and includes the ability to search your messages. And the Phone app has the ability to search for contacts from Call History.”

Offline maps: You can now save offline maps to a SD card.

Photo app: You can now mark local photos on your phone as favorites and have them shuffle on the Live Tile. Microsoft has also made some viewer improvements for zooming performance and file information, and added new launch points for rich editing. The company also is including new context menus (press and hold on a photo).

Storage settings: In build 10572, Insiders will see user-interface improvements to storage settings on your device that create a common experience across your PC and phone. Microsoft has enabled the storage settings page to allow users to install applications to expand storage such as and SD card or USB drive on BOTH your phone and PC.

Storage for PC and Phone

Here are the new fixes in Windows 10 Mobile build 10549

  • Notifications, such as new messages, can be received without first unlocking the device.
  • Cortana’s background activity has been optimized for power usage.
  • Microsoft has fixed some of the issues that were causing the Start screen to not load. Additionally, it has made some performance improvements to the Start screen.
  • The company has made performance improvements to Acton Center, including swipe to expand and dismiss notifications. Swiping to expand or dismiss notifications should happen more quickly.
  • The alarm icon now appears on the Lock screen when an alarm is set in the Alarms & Clock app.
  • The proximity sensor during calls is now behaving as expected on devices that may have previously failed to turn the screen off.
  • App downloads in the Store were sometimes getting blocked by a service hanging in the background – this should be resolved and app downloads should be more consistent.
  • The keyboard will switch languages less aggressively now.
  • Taping restart to apply an update will reboot the device immediately now.

The update is available immediately through the Fast ring of updates, and remember that you need to be running Windows Phone 8.1 to install the new build. Here are the known issues for this build.
