Important support change
One UI 7 or later does not support DeX for PC
Samsung states that DeX for PC is no longer supported on Galaxy devices released with or updated to One UI 7 or later. This does not mean every DeX mode disappeared: a compatible phone may still run DeX directly on a monitor or TV.

Choose the right DeX mode
DeX for PC is only one way to use Samsung DeX
Many confusing download pages treat every DeX connection as the same product. In practice, the Windows app, a direct monitor connection, and Wireless DeX have different requirements.
Device dependent
DeX on a monitor
The phone connects directly to a monitor or TV and produces the desktop workspace. No Windows installer is involved.
Monitor setupDisplay dependent
Wireless DeX
A supported Galaxy device can cast DeX to a compatible Miracast display. Expect more latency than a wired connection.

How to install Samsung DeX on Windows
Use these steps only after confirming that your Galaxy model and One UI version still support DeX for PC. Newer devices should use another connection mode.
- 1
Open the verified Samsung installer
Select Download for Windows and confirm that SamsungDeXSetupWin.exe comes from Samsung's Download Center.
- 2
Run the Windows installer
Open the downloaded file, review the Windows security prompt, and follow the installer. Do not use a similarly named file from an unknown mirror.
- 3
Connect a compatible phone
Unlock the Galaxy device and connect it with a data-capable USB cable. A charge-only cable cannot carry the connection.
- 4
Approve the phone prompt
Accept the DeX connection request on the phone. Keep the phone unlocked during the first connection while Windows completes device setup.
- 5
Confirm the desktop appears
The DeX workspace should open in a Windows window. If nothing happens, check One UI support, the USB mode, cable, port, and Samsung USB driver state.

Samsung DeX download for Windows FAQ
Can I still download Samsung DeX for Windows 11?
Yes, Samsung's official Windows entry page currently identifies SamsungDeXSetupWin.exe in the Download Center. However, Samsung says DeX for PC is not supported on Galaxy devices released with or updated to One UI 7 or later. The installer is mainly relevant to compatible devices on older software.
Why can I not find the Samsung DeX download link?
Samsung has shifted its support messaging because the DeX for PC app is a legacy product. Regional pages may omit the button or route users to general DeX information. The official Windows entry page and verified installer remain available when checked, but compatibility should come first.
Is Samsung DeX free to download?
The Windows installer is free. SamsungDex.wiki links to Samsung's server and does not charge for, host, or repackage the file. You may still need a compatible phone, data cable, monitor adapter, hub, or other hardware for your chosen setup.
Do I need to download Samsung DeX on my phone?
Usually no. On supported Galaxy phones and tablets, DeX is part of the system software. Look for Samsung DeX in Settings, Connected devices, or Quick settings. Avoid unofficial DeX APK files because they do not add hardware support to an unsupported phone.
Does Samsung DeX work on One UI 7 or One UI 8?
The distinction is important: Samsung says DeX for PC is not supported on One UI 7 or later, but compatible devices may still support DeX directly on a monitor or TV. Availability can also differ between phones and tablets.
Can I download Samsung DeX for Mac or Linux?
Samsung says the Mac app can no longer be downloaded, and there is no official Linux DeX client. For those computers, consider direct monitor DeX or another documented phone-integration tool rather than an unverified installer.
Is the Samsung DeX download a portable app?
No. The official Windows file is an installer named SamsungDeXSetupWin.exe. Websites advertising portable, modified, or cracked DeX packages are not providing the same verified Samsung download path.
What should I use instead of DeX for PC?
For Windows integration, Samsung recommends Link to Windows for supported calls, messages, notifications, files, and mobile apps. For a full phone-powered desktop workspace, connect a compatible Galaxy device directly to a monitor or use Wireless DeX with a compatible display.
