Turning Your Galaxy Phone into a Desktop with Samsung DeX

Samsung DeX turns a supported Galaxy phone or tablet into a desktop-style workspace the moment you connect it to a bigger screen.

  1. Connect to a monitor or TV

    Using a DeX-compatible cable or adapter, connect your Galaxy device to an external monitor or TV.

  2. Confirm DeX mode starts automatically

    Once the connection is recognized, a prompt appears asking whether to switch into DeX mode.

  3. Run multiple apps on the desktop-style screen

    On the larger screen, you can open several app windows at once and work with a mouse and keyboard.

  4. Connect a Bluetooth mouse and keyboard

    Pairing a Bluetooth mouse and keyboard makes working in DeX feel much closer to using a regular computer.

  5. Why it's worth using

    Even without a laptop on hand, connecting a supported phone to a monitor lets you comfortably work on documents or view a presentation on a much bigger screen.

One device, two very different workspaces

The same phone that fits in your pocket for quick tasks on the go can switch into a full desktop-style layout the moment it's connected to a bigger screen, without needing a separate computer for situations that call for more screen space.

A mouse and keyboard change how DeX actually feels

DeX is usable with just touch on the connected screen, but adding a Bluetooth mouse and keyboard makes window management, typing, and multitasking feel much closer to using an actual desktop computer, which matters most for longer work sessions.

Frequently Asked Questions

Does every Galaxy phone support DeX?

No β€” DeX is available only on select Galaxy devices, so it's worth checking your specific model's specifications before assuming it's supported.

Can I still use my phone normally while it's connected in DeX mode?

Yes, the phone's own screen generally remains usable as a trackpad or for separate tasks while the external display shows the DeX desktop.
