Since reset and repair were already tried, use a full unlink and relink sequence.
- On the Android phone, open Link to Windows.
- Select the Microsoft account under Linked Account.
- Go to Account Settings > Sign out and unlink account.
- Confirm Unlink.
- On the PC, open Phone Link.
- Go to Settings > Devices > Add new device.
- Start the pairing flow again.
- If Phone Link shows the current phone and hangs while connecting, first confirm both apps are fully updated.
- On Android: Link to Windows > Settings > About Link to Windows > Check for updates.
- On PC: Phone Link > Settings > General > expand the version area > Check for updates.
- If a QR code reconnect prompt appears, scan the QR code from the PC with the phone camera and complete the prompts on both devices. If needed, select the refresh button next to the connection status in Phone Link.
- Check the common connection blockers:
- Same Microsoft account signed in on both devices.
- Both devices have active Wi-Fi.
- Battery saver is off on both devices.
- On Android, turn off battery optimization for Link to Windows.
- On Android, make sure Do not disturb is off.
- On PC, make sure Phone Link is allowed to run in the background: Start > Settings > Privacy > Background apps.
- On PC, check Start > Settings > System > Shared experiences and select Fix now if shown.
- If both devices are on the same Wi-Fi but still cannot connect, check the router for Wireless Isolation or AP Isolation and disable it under advanced wireless settings. This setting can block devices on the same network from communicating.
- If it still hangs, do the full app reset on both devices:
- On Android: Settings > Apps > Link to Windows > Force Stop.
- On PC, go to https://accounts.microsoft.com/devices/android-ios, unlink the phone from the connected devices list.
- Then go to Start > Settings > Phone > Unlink this PC.
- Then go to Settings > Apps > Apps & features > Phone Link > Advanced options > Reset.
- Open Phone Link again and complete setup as a new link.
If code matching was attempted multiple times, close and reopen Phone Link on the PC and start setup again. After more than 3 failed code matches, the app can block linking and then switch to a permissions-based flow instead of code matching.
