Samsung has officially updated its support documentation to announce the end of support for its legacy Samsung DeX for PC application. The move marks a significant shift in Samsung's desktop strategy, guiding Galaxy smartphone users away from the downloadable desktop client and toward integrated alternatives such as Microsoft Link to Windows.
Understanding the DeX for PC Deprecation
Samsung DeX was originally introduced alongside the Galaxy S8 in 2017 as an Android-based desktop experience requiring a hardware dock (the DeX Station). In subsequent years, Samsung simplified the feature by enabling direct cable connections to external monitors and launching the standalone DeX for PC companion app for Windows and macOS.
While macOS support for DeX for PC was discontinued in early 2022, Samsung retained the Windows desktop client for several years. The company has now formally declared that updates and technical support for DeX for PC on Windows OS are being phased out.
Important Clarification: This deprecation specifically targets the downloadable companion application used to display DeX inside a window on a PC. Native Samsung DeX—which launches a desktop interface when connecting a Galaxy device directly to a monitor, TV, or smart display via USB-C or HDMI—remains fully supported on compatible flagship devices.
Why Samsung is Sunsetting DeX for PC
The decision to retire DeX for PC stems from a combination of strategic partnerships and technical evolution:
- Deepening Microsoft Partnership: Samsung and Microsoft have established a close ecosystem collaboration. Features such as phone screen mirroring, app streaming, clipboard sharing, and file transfers are natively handled via Link to Windows (Microsoft Phone Link).
- Technical Redundancy: Maintaining a separate virtualized desktop driver stack for Windows duplicated many capabilities already delivered by Link to Windows and Native DeX.
- Resource Allocation: Phasing out the PC companion app allows Samsung software engineers to focus on refining Native DeX features and expanding One UI optimizations for tablets and external displays.
Impact on Galaxy Device Owners
If you currently rely on Samsung DeX for PC to manage your smartphone from a laptop or desktop computer, here is what you need to know about the transition:
1. Existing Installations
Installed versions of the DeX for PC software may continue to operate on current Windows builds, but Samsung will no longer release security updates, bug fixes, or compatibility patches for future Windows updates or new Android/One UI releases.
2. Supported Alternatives
Samsung recommends two primary pathways depending on your workflow requirements:
- Microsoft Link to Windows (Phone Link): Best for users who want to view notifications, send SMS messages, access gallery photos, and mirror individual Android apps in separate windows on a PC.
- Native Samsung DeX: Best for users who require a full desktop productivity interface. This requires connecting your Galaxy device directly to an external monitor, dock, or USB-C Hub without an intermediate PC host.
How to Transition to Microsoft Link to Windows
For users seeking seamless integration between their Galaxy phone and a PC, setting up Link to Windows provides an immediate replacement for daily notification and file management:
- Ensure the Link to Windows toggle is enabled in your Galaxy device Quick Panel.
- Open the Phone Link application on your Windows 10 or Windows 11 PC.
- Select Android and scan the QR code displayed on your PC screen using your phone's camera.
- Grant the required system permissions to enable phone calls, notifications, photo syncing, and app streaming.
Conclusion
The deprecation of Samsung DeX for PC reflects the broader consolidation of cross-device productivity tools. While power users who preferred running a full DeX desktop container inside a Windows app window will miss the feature, the combination of Native DeX for monitor setups and Microsoft Link to Windows for PC synchronization offers robust alternative solutions for modern multi-device workflows.
