Data syncing and connectivity issues

Check for updates in the Phone Link  by opening Settings > About > Check for updates. Install any pending updates to make sure your content stays up-to-date.

You may also need to check for updates in the Link to Windows app on your Android device. Go to Settings > Check for updates, or go to Details >". . ." (More) > About Link to Windows.

To keep your content synced, your Windows PC and Android device need to be turned on, connected to the Internet, and we recommend having Battery saver turned Off (it may interfere with important notifications for the app). 

Yes, you can use your mobile data to sync with your PC. However, if you’re concerned about the effect on your data allowance, we recommend remaining on a Wi-Fi connection.

On your Android device:

  1. Open the the Link to Windows app.

  2. Select Settings .

  3. Select Sync over mobile data.

  4. Turn this option On.

To ensure the fastest, most reliable connection, your Android device and PC must be connected to the same trusted Wi-Fi network. This optimization isn't possible on a public connection — for example, in a coffee shop, hotel, or airport.

When you first connect to a Wi-Fi network on your Windows PC, you'll be prompted to set it as public or private (trusted). Learn more

These changes might not always be possible — for example, if your workplace controls or restricts your network connection.

Before we begin to change settings, we recommend quickly running through the following checks:

  • Double-check you’re using the same Microsoft account to sign in to both the Phone Link  and the companion app on your Android device.

  • Ensure Battery saver isn’t running on your PC or Android device, as this might affect connectivity.

  • You have an active Wi-Fi connection. Can you open your browser and navigate to your favorite website?

For some Android devices, your Battery Optimization settings may interrupt your connection. We recommend turning it off in the Link to Windows app on your Android device. 

Open Android Settings > Apps & notifications > App info > Link to Windows > Advanced > Battery > Manage Battery Usage > Battery optimization. Scroll down to Link to Windows, and then select Don't optimize.

On select Android devices, the steps may be as follows:

Open Android Settings > Apps > Link to Windows > Battery > Optimize battery usage. Select All from the drop-down list, scroll to Link to Windows, and turn the toggle Off.

Still not working? Continue below with the following steps. 

On your PC:

Check if the Phone Link  is set to run in the background.

  1. Select Start (or press the Windows logo key on your keyboard), then select Settings> Privacy > Background apps.

  2. In the list Choose which apps can run in the background, ensure that Phone Link is enabled.

Next, make sure that nothing is preventing you from sharing across devices.

  1. Select Start  (or press the Windows logo key on your keyboard), then select Settings> System > Shared experiences.

  2. If you see Fix now in Accounts, select it and follow the instructions.

On your Android device:

  • Make sure you can receive app notifications.

    • Go to your Android device Settings > Apps (or Apps & Notification on some devices) > Link to Windows, and then check that notifications are enabled.

Make sure Do not disturb is turned Off.

  • Go to your Android device Settings > Sounds (on some devices this may be Sounds & Vibration or Sounds & Notifications) and check that Do not disturb is turned Off.

If you’re still experiencing persistent connection issues, you can try to reset your app. You can also follow the steps to unlink your Android device.

If both of your devices are using the same Wi-Fi network but you still see an error message, this could be caused by a setting on your router.

Many routers have a Wireless isolation feature that allows you to lock down the network. If this Wireless Isolation (or AP Isolation) is enabled, then all devices connected to the Wi-Fi network will be blocked from communicating with other.

To disable Wireless/AP Isolation:

  • On most routers look for the Wireless > Advanced Wireless Setting, and then uncheck/toggle AP Isolation.

Updates

If you are seeing the "Update Required" page, it is because either your Windows PC and/or Android device is running an older version of the Phone Link and/or Link to Windows apps.

Troubleshooting features in the Phone Link 

If you're looking for troubleshooting for a specific feature in the Phone Link , find it in the list below:

How do I check I’m using the same Microsoft account for all my devices?

To successfully link your PC and Android device, you should sign in to the same Microsoft account on both. You can check this by following these steps:

On your PC:

  1. Open your browser and visit https://account.microsoft.com/devices/android-ios. Sign in with your Microsoft account. 

  2. Check if you Android device is listed under your account information.

On your Android device:

  • If you have the Link to Windows (downloaded) app:

I'm having issues with the Phone Link  when using Samsung DeX at the same time

Having both the Phone Link app and DeX open may cause issues with both apps. To ensure the best experience, only have one of these apps open at any one time.

Why can't I use the Phone Link  as a non-default user or two phone mode user (available in Korea only)?

You may encounter two phone mode if your mobile provider is in Korea. The Phone Link  does not currently support two phone mode or multiple profiles mode. Please contact your mobile provider to disable two phone mode so you can use the Phone Link .

If you have multiple profiles on your mobile device, the Phone Link  will only work if your mobile device is set to the default profile.
