Depending on the type of device you're connecting to when using DeX, you may want to add a keyboard and mouse! This will make it even easier to navigate the DeX screen. You can use a wired or wireless USB keyboard and mouse or pair a keyboard and mouse using Bluetooth. Of course, if you are using DeX on PC, you can just use the keyboard and mouse connected to your computer.

Wired or wireless USB keyboard and mouse 

For a wired or wireless USB keyboard and mouse, plug the USB cable or transmitter into the USB port on the DeX Pad or Station, or the USB port on your mobile device. You may need an OTG adapter to plug a USB-A device into the USB-C port.

Bluetooth keyboard or mouse 

Use your phone or tablet to open Settings, then tap Connections, and then tap Bluetooth. Make sure your keyboard or mouse is in pairing mode, and then select the desired device under Available devices. Tap Pair when prompted. 

Tablet with a compatible Book Cover keyboard 

You just have to connect the keyboard to the tablet. You can also have DeX start automatically by enabling Auto start when Book Cover keyboard is connected in Settings. 

Adjust physical keyboard settings 

If you need to change the keyboard's language, open DeX mode, and then navigate to and open Settings. Select General management, and then select Physical keyboard. Select Samsung Keyboard - English (US). From there, you can choose your preferred language. 

DeX settings can only be accessed in DeX mode. Setting changes made in DeX mode will be reflected in your mobile device settings as well. However, some configurations may not be supported.

Maybe you’re having some trouble reading the text in DeX mode. Just use the Samsung DeX settings to change any settings related to DeX mode. From DeX mode, open Settings, and then tap Samsung DeX. From here, you can customize your wallpaper, change display settings, access keyboard settings, try new features with Samsung DeX Labs, hide the taskbar, and much more.
