Microsoft simplifies unlinking and relinking Android devices in Phone Link app
To unlink your Android device from the Phone Link app on Windows, sign out of your Microsoft Account in both the Phone Link app on your PC and the Link to Windows app on your Android device. First, open the Phone Link app, go to Settings > Devices, and select "Sign Out." Then, do the same in the Link to Windows app on your Android device. Confirm the unlinking process when prompted. To re-link your Android device, ensure Bluetooth is enabled on both devices. Open the Phone Link app, select "Android," and choose your Microsoft account. Scan the QR code displayed on your PC with your Android camera, enter the six-character code, and follow the prompts to complete the linking process.
