Samsung DeX is a remarkable feature that allows you to connect your Samsung phone or tablet to a Windows PC or Mac and enjoy a range of Samsung apps on a larger screen. However, there may be instances when your device fails to detect the Samsung phone, preventing you from launching the DeX mode. In this article, we will explore ten effective solutions to fix Samsung DeX not working.
1. Check Samsung DeX Compatibility
Before troubleshooting the issue, it is essential to ensure that your Samsung device is compatible with DeX. The latest version of DeX for PC is limited to the newest Samsung flagship phones and tablets. It is available on Galaxy S10 and higher S-series models, Galaxy Note 10, Note 20, and Galaxy Fold series. However, it is not compatible with Galaxy tablets. To check for compatibility, you can visit the official Samsung support link.
2. Download Samsung DeX Software
To utilize Samsung DeX, you need to download the Samsung DeX software from the official website. Once you have installed the app on your PC or Mac, you can proceed to connect your phone using a data cable.
3. Ensure the Samsung DeX App Is Open
Samsung DeX automatically closes on your PC when it is not actively running. To resolve this issue, open the app on your PC after connecting your Samsung phone, and go through the installation process. Make sure that the app icon is visible on your computer’s Taskbar.
4. Reconnect the USB Cable
If you initially established a DeX connection but encountered errors later, there is a possibility that the USB cable connection may have become loose. Try disconnecting the USB cable and reconnecting your phone to the PC. However, if you are attempting to establish a wireless DeX connection, you can skip this step.
5. Check Wi-Fi Connection
When connecting your Samsung phone to a PC or Mac wirelessly, both devices must be connected to the same Wi-Fi network. If your phone is connected to a different Wi-Fi network or using cellular data, DeX will not function properly.
6. Use a Fast Wi-Fi Connection
If you experience glitches while using wireless DeX mode, it may be due to a slow Wi-Fi connection. Ensure that your phone is connected to a Wi-Fi network with a fast and stable internet connection. Connecting to a 5GHz Wi-Fi frequency, if available, is recommended for optimal performance.
7. Enable DeX Toggle on Samsung Phone
In some cases, the One UI fails to enable DeX mode on the phone automatically when it is connected to a PC. To resolve this, access the Quick setting toggle from the notification menu on your Samsung phone and enable the DeX toggle.
8. Use Another Port
If your PC’s USB port is malfunctioning, you may encounter difficulties in using Samsung DeX. Try connecting your phone to a different USB port on your PC and launch the DeX app.
9. Use the Supplied Cable
When connecting your Samsung phone to a PC or Mac, it is advisable to use the cable provided with your device instead of a random third-party cable. Using the supplied cable ensures optimal compatibility and performance.
10. Update DeX for PC App
An outdated DeX app on your PC can lead to glitches during DeX operations. To resolve this, open the DeX app on your PC and navigate to the Settings icon in the top right corner. Select “Update” under the “About Samsung DeX” option to download and install the latest software version.
Enjoy Samsung One UI on a Big Screen
Samsung DeX is an invaluable tool for individuals who frequently work on PCs or Macs. By connecting your Samsung phone to a larger screen, you can enjoy a seamless and enhanced user experience. Follow the aforementioned solutions to fix Samsung DeX not working and make the most out of this incredible feature.
