Microsoft has released the new Windows 10 20H1 Insider Preview Build 18908 for the users in the Fast ring. The 20H1 Build a lot of new features along with fixes and performance improvements. The new build focusses mainly on the Your Phone app on Windows 10.

Here’s what’s new in the latest insider preview build.

Your Phone app – Introducing even more new features

We’re bringing multiple new features to the Your Phone app in this build. Try them out and let us know what you think.

Phone screen – Accessibility features, keyboard language and layout, new phone models

We’re pleased to preview two new accessibility features – screen reading and focus tracking – as well as the ability to easily switch your Android phone’s keyboard language or layout while in phone screen.

Screen reading

For users of TalkBack, you can now enable the Your Phone Companion accessibility service, found under your Android phone’s accessibility settings, for smoother cross-device reading. Once both TalkBack and the Your Phone Companion accessibility services are turned on, Narrator will play from your PC, describing what you select and activate on your phone screen as you interact using your PC’s keyboard or mouse.

Focus tracking

You will now be able to interact with your Android phone’s apps at your preferred magnification while in phone screen. Focus tracking will seamlessly follow your keyboard focus and mouse pointer input.

To enable the focus tracking accessibility feature, you must first turn on the Your Phone Companion accessibility service and TalkBack on your Android phone. Once these services are enabled, you can turn on Magnifier on your PC using the shortcut: Windows Key and the Plus sign (+) or open the app from your Windows menu.

Keyboard language and layout

You will notice a new icon on your phone screen toolbar. Selecting this icon will take you to the phone settings page, where you can change your keyboard language or layout. This setting is specific to physical keyboards, so it only applies when you’re typing into your phone from your PC and will not change your phone’s language or keyboard configuration. If you type in different languages or like to switch your keyboard layout, give it a try.

Phone screen now supports additional Samsung phone models

The supported phone model list keeps expanding, we have now enabled support for the Samsung Galaxy A8 and Galaxy A8+. We will continue to expand the list of devices over time.

• If you enable both accessibility features simultaneously while using focus tracking, the magnifier rectangle will follow your navigation, but the visual Narrator rectangle will remain static, even though it will read out the correct text.

New messaging features

Your Phone can now sync over mobile data

• Enable “Sync over mobile data” under the Your Phone Companion app settings
• When enabled, you should see the ‘Connected to your PC’ toast on your phone

Colorful new icons

We’re also introducing a new look for both Your Phone and Your Phone Companion, to make them truly feel like part of the Windows family. The Your Phone Companion icon has started to hit phones already, and the Your Phone icon will arrive on Windows PCs in the coming days.

These features will gradually roll out to Insiders on 19H1 builds or newer, so it may take a few days to see them on your PC.

We’d love to hear your feedback, so let us know what you think by reporting issues under Your Phone > Settings > Send feedback.

Known Issues

• For Home editions, some devices might not see the “update installed” on the update history page.
• For Home editions, some devices might not be able to see the “download progress %” change on the Windows Update page.
• There has been an issue with older versions of anti-cheat software used with games where after updating to the latest 19H1 Insider Preview builds may cause PCs to experience crashes. We are working with partners on getting their software updated with a fix, and most games have released patches to prevent PCs from experiencing this issue. To minimize the chance of running into this issue, please make sure you are running the latest version of your games before attempting to update the operating system. We are also working with anti-cheat and game developers to resolve similar issues that may arise with the 20H1 Insider Preview builds and will work to minimize the likelihood of these issues in the future.
• Some Realtek SD card readers are not functioning properly. We are investigating the issue.
• If you use remote desktop to connect to an enhanced session VM, taskbar search results will not be visible (just a dark area) until you restart searchui.exe.
• There’s a noticeable lag when dragging the emoji and dictation panels.
• Tamper Protection may be turned off in Windows Security after updating to this build. You can turn it back on.
• In the Ease of Access settings, selecting a color filter may not take effect right away unless color filters option is turned off and back on again.
• Users navigating to the Graphics Settings page in the Settings application may experience Settings application crashes.
• The IME candidate window for East Asian IMEs (Simplified Chinese, Traditional Chinese, and the Japanese IME) may not open sometimes. We are investigating the issue. In the meantime, going to Task Manager and ending the “WindowsInternal.ComposableShell.Experiences.TextInput.InputApp.exe” task from the from the Details tab should unblock you if you experience this issue.
• We are aware of an issue with the Bopomofo IME where the character width is suddenly changed to Full width from Half width and are investigating.

Known issues for Developers

• If you install builds from the Fast ring and switch to either the Slow ring or the Release Preview ring, optional content such as enabling developer mode will fail. You will have to remain in the Fast ring to add/install/enable optional content. This is because optional content will only install on builds approved for specific rings.

Windows 10 Insiders in the Fast Ring can download the new update by Checking for Updates in the Settings app.
