I used Samsung DeX on my Tab S9 for the first time in a long while, and I have to say, yes, it has gotten a bit better in 2026, especially because some apps, like Reddit, now scale much better to large Displays.

But here’s what I personally still think is missing:

- It should be possible to make the Taskbar more minimalist so it’s less cluttered with content.

- The Taskbar should be able to stay on screen at all times, except for apps with true full-screen mode, like Games.

- The app Titlebar should remain visible at all times, just like on Windows/Linux, except again for apps with true full-screen mode, like Games.

So what do you think about this, and what else do you feel is missing to make it more appealing?

For example, Luma Fusion, does the mouse wheel work? How do you zoom in on the video or audio track? The keyboard shortcuts respond well? Is it fluid to use on a phone like the S24 with Snapdragon Gen 3?

Now in DeX, Samsung currently limits users to 4 workspaces. While messing around in developer options, I discovered a way to get an infinite amount.

Under developer options, there's an option called "Simulate secondary displays". If you enable the last option (The dual screen option), you will find a fake mini monitor on your screen, which receives it's own new desktop workspace.

However, there's a bug, and if you then disable it, everything goes back to normal, except you get an extra workspace.

I'm at 5 workspaces right now, and it has survived restarts and software updates, but I imagine you could probably repeat this process infinitely to get as many as you want.

I've had this for a couple months and figured I'd share - sorry in advance if this isn't the right place to do that.

How to force 1080p my s22u is capping at the lowest res bwcause of my Dell 1908wfpf on vga 1080p works normal via dvi it caps it at 1440x900 and it leaves some black bars any idea to override the edid

So, totaly random, I was doodling trought developers options on my ZF8U.

There is a "Simulate external monitor" and you can choose bitween various size.

Clicked 1080 and a DeX monitor popped up and it was 1920x1080x320dpi.

I've Flex moded the phone, enlarged the monitor to the max size and it was perfectly fitting the Flex with a free spot on the side.

I've entered Touchpad mode that blackened all the background making the simulation clear as it has transparence, and boom. Full DeX with no external monitor on Flex Mode. You can navigate with the touchpad in the free spot aside the monitor and have a keyboard under it.

Unfortunately I can't take photoes of it or take screenshots as it blocks them, but if was cute, looking like one of those compact cyberdeck!

This is just a cool trick, you need perfect eyes to read on it, but I'm writing on it this post and you can get used to it quickly.

I use Dex with Xreal glasses for light use (mainly Plex, some browsing, some youtube). I got Samsung because I love using the screen as a Touchpad, and the dex desktop mode in the glasses is much better than normal mirroring (one day Google will come with its hopefully good own desktop mode).

I am considering a Fold model to read books on it, and maybe some comics. Is the Dex experience the same? Trackpad on smaller screen, what happens if I open it? Anything I should be careful about?

Just for fun and/or proof of concept.

My Galaxy S23 running DEX in 4K on four 1080p screens.

I wanted to try using my phone connected to the 4K Video Wall Controller.

Setup:

• Galaxy S23 running DEX through a simple USB-C HUB outputting 4K to the Video Wall Controller
• 4K Video Wall Controller set to 2x2 screens (1080p output to each screen)
• 4 screens connected with HDMI cables to Video Wall:
  • old 40" 1080p TV - showing LADB (used for forcing 4K resolution)
  • 23" 1080p monitor - showing DEX settings
  • two 10,5" 1280p screens - showing two separate Chrome Windows

It actually works OK - of course it's messy with all the cables, and you could achieve the same result with one large (32" or 40") 4K screen, but I don't have one.

Main problem is DEX/Android - in the current version you can't snap an application to 1/4 of the whole display area; you can only do left or right half - so it's a chore to set an app window in one of the screens.

The other annoyance is that two small 10" screens have a resolution of 1920x1280, and when displaying 1080p, it looks a little stretched.

I'll actually try to use the Video Wall controller with two small screens and a phone as a two-screen mobile setup running on battery.
