The tablet has Dex as an option in the dropdown menu, but all that does is turn the tablet into Dex standalone mode, which is one of the modes stated to be available.
that may be so regarding hardware, but a bunch of us bought the device based on information from the Samsung website that it is supported. Perhaps the solution is to allow the A11+ to use wireless DEX?
I can confirm the same issue on a Galaxy Tab A11+ 5G running Android 16 / One UI 8.5, and I think Samsung needs to clarify the A11+'s actual DeX capabilities.
Standalone DeX works correctly. I can enable DeX from Quick Settings and use the desktop interface with resizable windows, multiple apps, keyboard, and mouse.
However:
There is no Samsung DeX menu under Settings → Connected devices. Searching Settings for "DeX" returns no DeX settings. Long-pressing the DeX Quick Settings tile does not open any additional settings. In the Quick Settings edit screen, Samsung actually identifies this same tile as "Wireless DeX." Despite that, tapping it only enables/disables standalone DeX. I cannot find any interface for selecting a wireless display. Smart View works with my Fire TV, but Smart View and DeX are clearly separate modes. If Smart View is enabled while DeX is running, One UI explicitly says that the desktop is hidden while Smart View is active.
This seems particularly confusing because Samsung's support documentation lists the Galaxy Tab A11+ as supporting Wireless DeX and instructs users to go to:
Samsung's own launch material also refers to "DeX Standalone Edition," which raises another question: Is the A11+ intentionally limited to standalone DeX, and the support documentation listing Wireless DeX is incorrect? Or is Wireless DeX supposed to be available on the A11+ and currently missing from the software?
Since other A11+ owners here have reported the same missing menu on both One UI 8.0 and 8.5, this does not appear to be an isolated configuration problem.
Could a Samsung moderator or product specialist please clarify:
Does the Galaxy Tab A11+ / A11+ 5G officially support Wireless DeX to an external Miracast display? If yes, how is it supposed to be initiated when the documented Samsung DeX settings menu does not exist? If no, why does Samsung's current compatibility documentation list the A11+ as supporting Wireless DeX and why does One UI identify the installed Quick Settings tile as "Wireless DeX"? Is external-display DeX planned for the A11+ in a future software update?
I'm happy to provide the exact model/build information, screenshots, or test anything Samsung recommends. At this point, though, several of us appear to be seeing the same behavior, so an authoritative answer from Samsung would be useful.
You’re not missing a setting. The A11+ supports DeX on the tablet itself, but the SM-X230 does not have USB-C video output, so HDMI/DeX-to-monitor isn’t actually possible. Samsung’s own specs list USB 2.0 and no MHL, and Samsung support has confirmed the USB-C port doesn’t support video output.
It appears that you are right about the hardware limits, but it would be good if Samsung could inform us whether DEX via wireless could be enabled on the A11+. This would at least allow us to use the tablet mostly per Samsung's own information/published capability.
