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.
