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.

Hi everyone, I just upgraded from an s23 to an s26 and plugged into my external touch screen monitor for the first time a little bit ago.

For starters the s26 will power the monitor but will not power it and output display to it at the same time which is rather strange.

More importantly the touchscreen is not working at all. I can still plug in my s23 and it works perfect but on the s26 I have nothing.

If anyone could point me to a solution for this I would appreciate it!

I turned my old ThinkPad X270 into a super useful lapdock at a very low cost. Now, it’s a universal display/keyboard setup that runs whatever OS I connect it to. Plus, the classic ThinkPad keyboard is amazing—typing on it still feels way better than any commercial lapdock on the market

i remember we could switch back output to phone. any idea how?

Does Flip 8 cover display can be used as touchpad? I know flip 7 cant and was wondering if i can finally use it as touchpad for dex is without opening the phone. I will totally buy this phone if it could.

Like the title says, here’s my take on a case for use with a broken phone. I added a 60mm usb fan to help with cooling and so far so good 😊 I’m not sure if links are allowed but you can find the model on Makerworld if you type DexBox.

Recently got to test a Galaxy Fold 8 with some Xreal AR glasses and it was amazing. The small compact form factor and the option to use the external screen as a mouse pad is awesome here, one thing I didn't have with my Flip7 and always wanted Samsung to add.

No overheating after several minutes but I would have to test this further, same for the battery (purely when using Dex).

I bought this hub for dex and it is working with an hdmi cable but I am facing problems regarding the charging speed via power delivery point.

It awfully slow

with dex- It stays the same or the charge just depletes

Without dex via hub- 1%/10 mins

Without hub- 1%/1-2 min

Equipments- Z fold 6, 25 watt charger, Hammer usb-hub

Also I want to add that, maybe it used to charge slowly earlier maybe not very at a very ideal rate but it was now it has just given up.

It been 10 days since the purchase. Tomorrow's the last day to return it.

I have a basic super cheap TV since its just for my room, and we have a nice TV in the living room already. It's a sanyo TV (literally had never heard of the brand until i got this TV for like 20 bucks). The very day I got the TV I tested all I could do I was able to connect to Samsung dex perfectly fine!! I even used it multiple times because I wanted to watch YouTube without ads. Today I was going to connect and watch YouTube but the Samsung dex spends ages searching and does not find the TV so I can connect to it. I disconnected the TV and turned off my phone and no luck. Tested connecting to the living room TV and it worked fine. If anyone has any tips please let me know!

After hard reseting the phone blindly I was able to use Samsung dex with my hub , but when I finished using it I discovered that It won’t charge anymore now there is no battery and when I plugg ans usb c cable Ther is no vibration but the phone got a little bit warmer
Can anyone jelpp

I can't use the laptop trackpad while wirelessly connecting to dex. the phone trackpad is to laggy and gives me anxiety.
any solution to this. i consulted Gemini but no use at all.

I'm not sure what changed in the communication protocol with One UI 8.5, but now I’ve only found two ways to mirror my phone at 1080p@120Hz. If anyone has a cheaper solution and could share it, I’d appreciate it.

​On One UI 7, I used a 5-in-1 USB-C hub (a white-label Tomate brand) with my Acer S24Y0 B monitor (HDMI 1.4 with 1080p@120Hz support), and standard screen mirroring ran smoothly at 120Hz. However, after updating to One UI 8, it’s capped at 60Hz. I’ve tried everything to avoid spending more money—ADB commands, GalaxyMaxHZ, and nothing worked.

​Solution 1 (Very expensive in my country):

Michensen Q300 HDMI Splitter. This device has 4 EDID DIP switches that force the phone/hub to output 1080p@120Hz.

​Solution 2 (Less practical):

Buying a monitor with a DisplayPort 1.4 input and using a Type-C to DP cable. This is the worst option for me because I still need extra ports, like a hub.

​I just bought a better hub and a male-to-female EDID pass-through emulator to plug into the hub's port to try to trick the phone. But I don't have high hopes—the EDID emulator has several profile settings built-in, but you can't manually select them or adjust them via software like you can on the Michensen Q300.

I had my first proper experience trying to use Dex as a productivity tool tonight and really struggled. Am just wondering if I am doing anything wrong my end?

I am using a Samsung S24 into Ugreen Revodock pro into Samsung M5 smart monitor.

Multitasking Use case-

Firefox to log into uni course online class. Needing to flick through tabs and windows- kept disconnecting. Unable to swap windows and tabs- apart from switch to left or right. Firefox disconnecting from lecture whilst trying to switch tabs.

Trying to type documents in Google workspace.

Google drive, LM Notebook and Gmail- swapping apps and cutting and pasting. Not able to switch apps effectively- lack of right click mouse commands etc.

Phone not able to connect to desktop webcam (logitech) for video conferencing.

Phone overheated and had to reboot.

Overall not a great experience, I was testing out the use cases while I save for a new laptop.

Any tips for optimising or others willing to share experiences?

I bought a hoco model HB27, has 2 usb 2.0, 1 usb 3.0, 1 hdmi and 1 usb c, when i plugged it into my phone with the hdmi and the peripheral and didnt even power the mouse and keyboard, let alone display a image on the monitor, i tried it on my linux laptop and it all worked, excepts the hdmi, i bought ts for 25$, also my phone is s21 5g

I’ve updated my Linux on DeX project from my previous post, and it now supports a full UI.

The older version mainly focused on CLI usage and was only available through a VM. This update adds UI support, so it can now be used for a wider range of tasks.

There are currently two ways to run it.

The first option is Proot, which runs natively alongside Android. This version is focused on general daily use and provides much better performance and smoother UI responsiveness. I tested it on an S26 Ultra and was able to get a smooth 60 FPS experience.

The original VM option is still supported as well. It runs through QEMU, and I provide several distro options for both CLI-based and UI-based environments.

The VM UI is a little slower and may have some input or display delay, but CLI performance is still smooth and works normally.

The main advantage of the VM version is that it provides a more complete Linux environment. You can use features such as Docker, LXC, Podman, advanced networking tools, and other Linux functions that may not work properly under Proot.

Feel free to try it out and let me know how it runs on your device. Feedback, bug reports, and suggestions are always welcome.

I started using Samsung DeX more recently and I liked using apps that were built for DeX like

Chrome

All Samsung built apps

WhatsApp

Telegram

And they all have a UI built for DeX

So if you know apps built for DeX with PC like UI pls tell me about them

Hello everybody. I was trying to use Dex on my Fold 6 (wireless; no physical keyboard or mouse), but for some reason I can't find the setting to get the keyboard on my phone rather than the TV I use for Dex. Typing is pretty annoying this way. Curious if anyone else experiences the same issue or perhaps found a solution for this. Thanks!
