Completely remove the existing phone association from Phone Link, Windows Mobile Devices, Bluetooth, and Link to Windows before pairing again; resetting or reinstalling the apps does not necessarily remove these saved associations.
1. Fully unlink the old connection
Close Phone Link, then remove the phone from every location in this order:
- Phone Link
- Open Phone Link → Settings → Devices.
- Select the three-dot menu beside the phone → Remove.
- Windows Mobile Devices
- Open Settings → Bluetooth & devices → Mobile devices → Manage devices.
- Remove the phone if it appears.
- Windows Bluetooth
- Open Settings → Bluetooth & devices → Devices.
- Remove every entry corresponding to the Android phone.
- Android Link to Windows
- If Link to Windows is built in: open Settings → Connected devices → Link to Windows, select the Microsoft account, and tap Sign out.
- If it was downloaded: open Link to Windows → Settings → Accounts → Sign out.
- Android Bluetooth
- Open the phone’s Bluetooth settings.
- Select the Windows PC and choose Unpair or Forget.
Microsoft documents that all these locations may need to be cleared to fully disconnect a device.^1^
Restart both devices after completing the removal.
2. Reconnect through Phone Link—not Bluetooth Settings
Before relinking:
- Connect the PC and phone to the same trusted Wi-Fi network.
- Turn off Battery Saver on both devices.
- Sign in to Phone Link and Link to Windows with the same Microsoft account.
- On Android, set Link to Windows battery usage to Don’t optimize or Unrestricted:
- Settings → Apps → Link to Windows → Battery
- Select Don’t optimize, Unrestricted, or turn off Optimize battery usage, depending on the phone.^2^
Then:
- Open Phone Link on Windows.
- Choose to add an Android device.
- Open Link to Windows on Android and scan the QR code shown on the PC.
- Grant the requested permissions.
- Wait until the phone shows Connected in Phone Link before configuring Calls.
Phone Link setup uses the QR-code workflow and requires the devices to be nearby and able to communicate over the same Wi-Fi network.^3^
If both devices are on the same Wi-Fi but still cannot communicate, check the router for Wireless Isolation/AP Isolation and disable it. A VPN, firewall, public Wi-Fi, or managed work network can also block device-to-device communication.^2^
3. Treat the immediate Bluetooth disconnect separately
Phone Link’s general connection and its Bluetooth-dependent Calls feature are separate. First confirm whether Phone Link connects over Wi-Fi. If Phone Link works but Calls does not, open Phone Link → Calls and perform the Bluetooth pairing from there.
If Android still pairs and immediately disconnects—even outside Phone Link—repair the PC’s Bluetooth driver:
- Open Settings → Windows Update → Check for updates and install available updates.
- Open Device Manager → Bluetooth.
- Right-click the Bluetooth adapter → Update driver → Search automatically for drivers.
- If Windows finds nothing newer, obtain the Windows 11 Bluetooth driver for the exact PC model from the PC manufacturer.
- Restart Windows.
If updating does not help:
- Return to Device Manager → Bluetooth.
- Right-click the Bluetooth adapter → Uninstall device.
- Restart the PC; Windows should reinstall the adapter automatically.
If the problem began immediately after a driver or Windows update, use Bluetooth adapter → Properties → Driver → Roll Back Driver, when that button is available.^4^
If Intel Unison, Virtoo by LG, or another phone-integration application is installed, disable or sign out of it before pairing because such applications can conflict with Phone Link calling.^5^
