All new features, bug fixes and known issues in the Windows 10 Build 10051 For Phones

Today, Microsoft released a new Build 10051 of the Windows 10 Technical preview for phones. The build not only supports more Lumia devices but brings new features that users will experience for the first time. Microsoft has also fixed some major bugs in this build.

Here are the full list of new features 

Project Spartan: An early version of Project Spartan is available in this flight. It uses new rendering engine to give greater interoperability with the modern mobile web, and includes early versions of Reading View and Reading List. For now, Project Spartan is not the default browser, and exists side-by-side with IE11. You can find it in the All Apps list and pin it to your Start Screen from there. Please send feedback on sites and design. For more details on Project Spartan on the phone – see this blog post.

New mail and calendar apps: Outlook Mail and Outlook Calendar are the new built-in mail and calendar universal apps for Windows 10. These new apps bring a fresh UI, with a toggle to freely move between your email and calendar without returning to the Start screen. Outlook Mail includes customizable Swipe Gestures, letting you swipe right or left to take actions like delete, flag, move or mark as read/unread. Outlook Mail leverages the familiar capabilities of Word to create a richer email experience. You can do formatting tricks like inserting tables, adding pictures and using bullets and text. Outlook Mail and Outlook Calendar connects to Office 365, Exchange, Outlook.com, Gmail, Google Calendar, Yahoo!, IMAP, POP and other popular accounts.

New Phone and Messaging apps: The Messaging app has a new visual design. You can also easily upgrade from a messaging conversation to a voice call with one click of the phone icon in the new app bar.

New People app: The new universal People app has a new visual design but will continue to be the comprehensive list of all your contacts across the services you care about such as Exchange, Outlook.com, Gmail, Facebook, etc. You’ll be able to easily manage all your contacts and quickly connect with them. 

New Maps app: It offers you the features and tools you need to explore and navigate the world. This includes the best maps, aerial imagery, rich local search data, and voice guided navigation experiences from both Bing Maps and HERE maps, integrated together for the first time into a single app for Windows.

Updated App Switcher: Check out the updated app switcher by pressing and holding the back button on your phone to see your recently used apps. We’ve added support for landscape when invoked from an app being viewed in landscape. For large phones like the Lumia 1520, a new grid layout is introduced so you can be more efficient at switching between apps. The length of recently used apps is extended to 15.

The major bug fixes in the latest build are-

Updated  keyboard: The keyboard layout now has period, comma and emoji keys on first page of keyboard. Language switching is enabled by press-and-hold on the &123 key. There is also an option to replace the emoji key with the language switching key.

The Cortana icon resolution now scales with tile size

Fixed Photo app issue that failed to launch periodically when attempting to add a attachment to an email, OneNote or Facebook item.

Fixed the issue where the Microsoft Band wouldn’t sync with your phone after upgrading to Windows 10.

The Photos app’s tile will now pick up the phone’s theme color before it’s launched and then start showing pictures from your collection including OneDrive in the Live tile.

And since the Windows 10 Build 10051 for phone is pre production software, users can expect to see some bugs. Check out the list below-

• There might be situations in which auto-upload of your Camera Roll to OneDrive may not be working. Please be sure to back up your photos especially if you need to use the Windows Phone Recovery Tool to go back to Windows Phone 8.1.
• The Office Hub has been removed from this build. You won’t be able to open Word, Excel, PowerPoint or OneNote files in this build. Preview versions of the universal Office apps will be available in the coming weeks.
• We are redoing how text messages are handled and processed by Cortana so in this build text messages cannot be read out over Bluetooth.
• After upgrade, some apps that have been installed onto a SD memory card will fail to launch. To fix this, uninstall and reinstall the apps.
• About 1% of the time, incoming phone calls may not play a ringing sound.
• Call + SMS filtering will not work after upgrade.
• For people upgrading their phone from Build 9941, there is a bug in which your phone’s MMS settings will be lost after upgrade. The new Messaging app doesn’t yet have the ability to re-enter these settings. You will need to use the Windows Phone Recovery Tool to go back to Windows Phone 8.1 and then upgrade to this build to get MMS working again.
• Also for people upgrading their phone from Build 9941, the tiles on your Start screen for the Camera and Photos apps may be missing or corrupt. You will have to unpin any corrupt tiles and re-pin the apps to your Start screen.
• On some phones, due to a scaling bug the dismiss button won’t be visible when an alarm is triggered. To stop your phone from “alarming “just touch the arrow and swipe up on the notification and off the screen to end the alarm.
• On phones with 512MB of memory, apps can randomly crash due to an issue with memory management.
• Flight mode cannot be enabled.
• Data connections can’t be disabled.
• You may need to re-pin the Phone app after upgrade.
• The Insider Hub is now included on Phone but may fail to launch on some phones.
