How to Fix Samsung DeX Not Working on Galaxy Phones in Easy Steps

Samsung DeX connects your qualifying Samsung phone or tablet to a Windows PC or Mac, allowing you to use Samsung apps like Gallery, Office programmes, and more on a larger screen. But what if your gadget doesn't recognise the Samsung phone and the DeX mode doesn't start? Learn how to fix Samsung DeX not working.

How to Fix Samsung DeX That Isn't Working

To perform as stated, Samsung DeX is reliant on a number of things. Let's start by looking for DeX-compatible phones and tablets, and then go over some troubleshooting tips.

1. Make sure Samsung DeX is compatible with your device.

Only the newest Samsung flagship phones and tablets are compatible with the latest DeX for PC version, which does not require any DeX accessories.

Galaxy S10 and higher S-series phones, Galaxy Note 10, Note 20, and Galaxy Fold series all include the feature. It isn't compatible with Galaxy tablets. Users can connect the phone wirelessly or via USB-C connection with the DeX for PC. There is no requirement for a DeX Station or a DeX cable.

The official Samsung support link can also be used to check the PC and Mac system requirements.

2. Ensure that you have the Samsung DeX software installed.

Samsung DeX isn't a simple plug-and-play experience. The Samsung DeX software is available for download from Samsung's official website.

You're ready to utilise the data cable and connect your phone once you've installed the app on your PC or Mac (yep, Samsung DeX is available on both PC and Mac).

3. Double-check that the Samsung DeX app is open.

When Samsung DeX isn't in use, it shuts down automatically on the PC. After you've connected your Samsung phone to your computer, open the app and follow the on-screen instructions to complete the installation.

Make that the app icon is visible on the computer's Taskbar.

4. Connect the USB cable again.

Did you get the DeX connection up and running at first, but subsequently received errors? Chances are, the cable connection might have loosened up. You can detach the USB cable and try connecting your phone to the PC again.

If you're looking to set up wireless DeX from your phone to your PC, you can skip this step.

5. Verify the Wi-Fi connection

To connect your Samsung phone to a PC or Mac wirelessly, both devices must be connected to the same Wi-Fi network. You won't be able to utilise DeX if your phone is linked to cellular data or a different Wi-Fi network.

6. Make use of a strong Wi-Fi connection.

If you have a slow Wi-Fi connection at home or at work, wireless DeX mode will cause you problems.

Make sure your phone is linked to a Wi-Fi network with at least double-digit speeds. You can only connect to a 5GHz Wi-Fi network, not a 2.4GHz one (assuming you have a dual-band router at home).

7. Turn on the DeX toggle on your Samsung phone.

The One UI will automatically enable the DeX toggle when you connect your Samsung phone to a PC. When you start the Samsung DeX software on your PC, the OS may fail to enable DeX mode on your phone, and the feature will not work.

From the notification menu, go to Quick settings toggle and enable DeX toggle.

8. Switch to another port

Your computer's USB port may be broken in some instances. You will not be able to use Samsung DeX on a PC, no matter how hard you try.

Most PCs have many USB ports that can be used. Switch to a different port and run the DeX programme.

9. Switch to a different cable

Are you trying to connect your Samsung phone to a PC or Mac with a random third-party cable? The latest Samsung flagship phones do not have a charger, but they do include a cord.

To connect your Galaxy phone, try to utilise the cable that came with it.

Update the DeX for PC app.

DeX activities may be hampered by an out-of-date DeX app on your PC. The DeX app isn't available in the Microsoft Store since Samsung hasn't made it available. To install the latest update, follow the steps below.

• 1. Go to the Settings icon in the top right corner of the DeX app on your PC.
• 2. From the About Samsung DeX menu, choose Update and download the most recent software version.

On a Big Screen, Enjoy Samsung One UI

Samsung DeX is a must-have add-on for anyone who spends a lot of time on a computer or a Mac. Simply connect your phone to Samsung DeX via a cable or a wireless connection, and you're ready to enjoy your phone on a larger screen.
