How to Fix Samsung Galaxy S25 Ultra Link to Windows Not Working

Link to Windows lets your Galaxy S25 Ultra connect directly to a Windows PC so you can view notifications, send messages, access photos, and even mirror your phone screen. When the feature stops working, the phone may fail to connect, the pairing may break, or the PC may not detect the device at all.

This problem is usually caused by connection settings, account issues, or permission restrictions. The fixes below focus on restoring the connection and making sure both devices communicate properly again.

Why Link to Windows Is Not Working on Your Galaxy S25 Ultra

• The phone and PC are not signed in to the same Microsoft account.
• Link to Windows is turned off in the phone settings.
• The Phone Link app on Windows is outdated or not configured.
• Wi-Fi or Bluetooth connectivity problems interrupt the pairing process.
• Permission settings prevent the phone from sharing notifications or files.

Check if Link to Windows Is Enabled

The connection cannot start if the feature is disabled on your phone. Sometimes updates or resets may turn it off automatically, which stops the PC from detecting your Galaxy device.

1. Open Settings, and then tap Connected devices.
2. Tap Link to Windows, and then toggle on the switch.
3. Tap Sign in, and then log in using your Microsoft account if needed.

Make Sure Both Devices Use the Same Microsoft Account

Your Galaxy S25 Ultra and your PC must use the same Microsoft account to sync data. If they use different accounts, the pairing will fail or disconnect repeatedly.

1. Open Settings, and then tap Connected devices.
2. Tap Link to Windows, and then check the Microsoft account listed.
3. On your PC, open Phone Link, and then confirm it uses the same account.

Check Wi-Fi Connection on Both Devices

Link to Windows works best when both devices share the same Wi-Fi network. Different networks or unstable signals can interrupt the connection.

1. Swipe down from the top right of the screen, and then tap the Wi-Fi icon.
2. Tap the connected network, and then confirm it matches your PC network.

Restart the Phone Link App on Your Computer

Sometimes the issue is not on the phone but on the computer. Restarting the Phone Link app refreshes the connection and allows the PC to detect your device again.

1. Open the Start menu, and then launch the Phone Link app.
2. Click the Settings icon, and then choose Restart or reconnect the device.

Allow Required Permissions on Your Phone

Link to Windows needs several permissions to function properly. If these permissions are denied, features such as notifications, messages, or photo access may stop working.

1. Open Settings, and then tap Apps.
2. Tap Link to Windows Service, and then tap Permissions.
3. Enable all required permissions, and then reconnect the device.

Restart Your Galaxy S25 Ultra

A simple restart refreshes wireless connections and background services. This often resolves temporary software glitches affecting the Link to Windows feature on devices running OneUI 7.

1. Swipe down from the top right of the screen, and then tap the Power icon.
2. Tap Restart, and then wait for the phone to reboot completely.

Once the phone reconnects to your PC, Link to Windows should resume syncing messages, notifications, and photos normally. In most cases, the issue disappears once both devices are signed in properly and connected to the same network.
