You can tap into the power of Your Phone app with Link to Windows integration on select Surface Duo and Samsung devices to instantly access your Android phone’s mobile apps directly from your Windows 10 PC.
Apps replaced the phone screen option in the left pane of the Your Phone app, but Phone screen is still available. Phone screen will mirror your Android phone screen the same way it did before, but it will be on a separate window from the Your Phone app. Apps provides an easier way to interact with all of the apps installed on your Android device by launching them directly.
The Phone screen feature only works when your Android device and Windows 10 PC can communicate with each other. They will both need to be turned on, linked, and connected to the same network (for example, your home Wi-Fi).
The Your Phone Companion accessibility service is for those using a screen reading or focus tracking tool on a Windows 10 PC.
When the Your Phone Companion accessibility service is enabled, it lets you control all your Android phone's apps from your Windows 10 PC using Android keyboard navigation while receiving Narrator spoken feedback from your PC speakers or headphones. You can navigate through phone screen on your PC by using your keyboard and mouse.
This tutorial will show you how to enable or disable the Your Phone Companion accessibility service on your Android phone with Your Phone app on Windows 10 PC.
