Resolving Samsung DeX Issues on Windows and Mac

Before we dive into specific troubleshooting methods, it’s crucial to ensure that your device is compatible with Samsung DeX. DeX is available for Samsung S8 series devices and newer, excluding the Galaxy Flip series. Additionally, for wireless DeX, your TV must support MiraCast technology, while for USB cable connections, ensure your PC does not have an ARM processor, as this may not be compatible with Samsung DeX. To verify compatibility, consult the official Samsung website for a list of supported devices.

Check the USB Connection(Mac & Windows)

A common issue is an unreliable USB connection between your phone and PC or Mac. To establish a stable connection, follow these steps:

Plug the USB cable firmly into your Windows or Mac.

If errors persist, try different USB ports on your PC or Mac.

Consider using a USB hub if you’re using an older PC.

Disable Power Saving Mode(Smartphone)

Power-saving mode can hinder Samsung DeX functionality. To turn off Power Saving Mode:

Access your device settings.

Navigate to Battery and Device Care and then Battery.

Disable the Power Saving toggle.

Ensure your smartphone is adequately charged if you’re using wireless DeX.

Connect to the Same WiFi Network

If you’re using a laptop to connect to Samsung DeX, both your smartphone and the receiving device must be on the same WiFi network. Avoid using different WiFi networks, as it can disrupt the connection. If available, opt for the 5GHz band instead of the default 2.4GHz band for improved performance.

Configure USB Mode on Your Smartphone

Upon connecting your Samsung Galaxy to your laptop or PC, you’ll be prompted to select a USB mode(e.g., Transferring files, USB tethering, Transferring photos, Charging Phone only). Ensure “Transferring Files” USB mode is selected to enable Samsung DeX. You can access this option from your device’s notification panel.
