Fix 1: Verify the USB Connection (Mac & Windows)


A frequent issue with Samsung DeX is an unstable USB connection. Over time, the connection between your phone and the USB cable may become loose, causing frequent disconnections. To ensure a stable connection:

  1. Insert the USB cable securely into your Windows or Mac PC.
  2. If issues persist, try different USB ports on your PC or consider using a USB hub if your PC is older.

Fix 2: Disable Power Saving Mode (Smartphone)


Power Saving mode on your Samsung Galaxy can interfere with Samsung DeX’s functionality. Hence you’ll need to turn it off for the Samsung DeX to work. To resolve this:

  1. Access your device’s Settings.
  2. Navigate to “Battery and Device Care” and select “Battery.”
  3. Turn off the Power Saving toggle.
  4. Ensure your smartphone has sufficient charge if you’re using wireless DeX.


Fix 3: Ensure Both Devices Are on the Same Wi-Fi Network


When connecting your laptop to Samsung DeX, it’s essential that both your smartphone and the receiving device (laptop) are connected to the same Wi-Fi network. Using different Wi-Fi networks can hinder communication between Samsung DeX and your laptop. Consider using the 5G band, if available, instead of the default 2.5GHz band for improved performance.

Fix 4: Check USB Mode on Your Smartphone


Upon connecting your Samsung Galaxy to your PC or laptop, you’ll be prompted to select a USB mode, such as transferring files, USB tethering, transferring photos, or charging the phone only. To ensure Samsung DeX works correctly:

  1. Confirm that the “Transferring Files” USB mode is selected.
  2. Activate Samsung DeX after choosing this USB mode, which can be accessed from your notification panel.


Fix 5: Reinstall the DeX App (Windows Only)


If you’re using an older version of the Samsung DeX application on Windows and experiencing issues, consider reinstalling it with the latest version from the official Samsung DeX website:

  1. Visit the official Samsung DeX website and download the latest Samsung DeX system file.
  2. Once downloaded, install the new Samsung DeX on your Windows PC.
  3. Connect it to your smartphone, and you should be able to use Samsung DeX without errors.

Troubleshooting Samsung DeX connectivity issues on Windows or Mac can be a straightforward process by following these steps. Firstly, ensure your device is compatible. Then, check your USB connection to guarantee a stable link. Next, disable Power Saving mode to avoid any hindrance. Furthermore, connect to the same Wi-Fi network for a smoother experience, and make sure to select the correct USB mode on your smartphone.
