The Phone screen feature in the Windows 10 app only works when your phone and PC can communicate with each other. They’ll both need to be connected to the same network (for example, your home Wi-Fi).
If attempting to use Phone screen in your workplace, a successful connection may not always be possible. In that event we’d recommend talking to your IT department or network administrator.
Common troubleshooting for Wi-Fi:
- Check if your phone is connected to mobile data instead of Wi-Fi, by going into your phone’s Settings > Connections > Wi-Fi and ensure your Wi-Fi toggle is turned “On” and underneath your current network is “connected”.
- Check if your phone is connected to the same Wi-Fi network as your PC.
- Start by checking your phone’s connection in Settings > Connections > Wi-Fi and note the name of the network under the current network heading.
- On your PC go to Settings > Network & Internet > Wi-Fi - check your PC Wi-Fi is turned “On” and the connected network is the same as on your phone.
- You may have two different Wi-Fi networks, e.g. one that uses the 2.4GHz band and the other 5GHz. If you click on your PC/phone Wi-Fi icon you should be able to see these networks in the list. Try connecting to the same network on both devices.
- Are you behind a firewall or using a VPN? If so, it could be blocking communication between your devices, you could try disabling these to see if this fixes the problem.
If you see an error message indicating your PC couldn't connect to your phone, it could be for a variety of reasons. Here are few things to try:
On your Android phone, check that:
- Your phone is turned on.
- Battery Saver is turned on your phone.
- Your phone isn't in Airplane mode.
- Your phone and PC are connected to the same network or Wi-Fi.
- You're signed into the Your Phone Companion app with the same Microsoft account as you're using on your PC.
On your PC:
- Check if your PC is connected to the Internet.
- Make sure Battery Saver is turned off on your PC.
- Check that your system accounts are working correctly. In Windows, go to Settings > System > Shared experiences. If you see a Fix now link in the Accounts section, select the link and follow the instructions.
