Samsung to ditch DeX support for Windows 7 and macOS
If you use Samsung's DeX with a Windows 7 PC or Mac, you're out of luck as of next year.
What you need to know
- Samsung will discontinue DeX support for Windows 7 and macOS in January 2022.
- Windows 10 and Windows 11 appear to be unaffected by this change.
- Samsung devices that support DeX can connect wirelessly or through a wired connection to supported devices.
Samsung will discontinue DeX support for Windows 7 and macOS devices in January 2022. Samsung's website for DeX was recently updated to outline the end of support for macOS and Windows 7. People will still be able to use DeX on other devices, including external monitors and PCs running Windows 11 or Windows 10.
The Samsung page for DeX now states:
The DeX for PC service for Mac/Windows 7 OS will be terminated as of January 2022. For any further questions or assistance, please contact us through Samsung Members.
Some Mac owners on Reddit have seen a similar message appear on their devices. That message specifies that people will still be able to use DeX if it's installed but that the feature won't receive any future support or updates. People won't be able to download DeX after January 2022 on devices that lose support.
Samsung's DeX allows you to connect your supported phone to monitors and computers to switch to a desktop mode. The interface of DeX looks similar to that of Windows, making it much more usable for multitasking and getting work done. DeX serves a purpose directly on devices like the Samsung Galaxy Tab S7 FE, which switches to desktop mode when you attach a keyboard. You can also project your phone into DeX mode on supported computers and external monitors.
Since most people have moved away from Windows 7, this change probably won't affect PC owners. Any person with a combination of a Mac and a Samsung phone or tablet will have to find an alternative solution.
