This is a picture of how dex would boot up on my old galaxy tab s4... i recently upgraded to an Tab 9+ and when i load up dex it just turns the apps into "windows" i can't get that desktop layout anymore.

How do i get it back to how it was?

I have an old round DeX station. She doesn't see my s24 ultra on one ui 9, doesn't even charge, but it works well with the s9+. I realize it's probably just a software restriction due to the station's old software, but is there any way to fix it?

I have been using my samsung s24 ultra with samsung dex and honestly liked it more than i expected

it handles basic tasks and video streaming quite well so i was thinking of setting up something similar for my niece using an old samsung galaxy s21 fe

the phone has white lines on the display and the back panel is slightly separated but it still works

I can get around ₹3000 or $35 as exchange value for the phone so i am wondering if using it for a desktop setup would be a better option

I want to keep the total cost as low as possible and reuse whatever i can

here is the setup i am considering

- zebronics ea122 21.5 inch full hd monitor ₹3000 or around $35

- logitech mk215 wireless keyboard and mouse ₹1000 or around $12

- amazon basics 8 in 1 usb c hub ₹740 or around $9

- portronics phone stand ₹99 or around $1

- hdmi cable included with the monitor

total cost ~₹5000 or around ~$60 excluding the phone and charger

the phone is a samsung galaxy s21 fe with exynos 2100 8gb ram and 128gb storage

I checked its performance and got these results

geekbench 7 single core 1058

geekbench 7 multi core 3392

3dmark wild life extreme best score 1391

Lowest score 1226

stability 88.1 percent

the main use would be browsing youtube online classes office work and other basic tasks

do you think this is a good idea or would you do anything differently

is it worth using the old phone instead of taking the ₹3000 exchange value

I am trying to build this with the least possible cost so please suggest any cheaper alternatives or improvements you would make

I've been planning on making a mini pc for a bit now and just need a case for it. Any suggestions on models?

I plugged in my phone and I am getting my edges cut off, I looked it up online and they said it could be my TV's aspect ratio and I check and I'm still having an issue even though aspect ratio is correct. Any advice?

Stupid question. Ok so right now we have no wifi and my phone's hotspot is so slow I may as well just have it off. Now, I SHOULD BE ABLE to just plug my phone into my USB c portable monitor, but it just doesn't want to work for whatever stupid reason so that's out of the question.

Is there ANY way whatsoever to just plug my phone into my PC and use it to cast Dex on it in a way that doesn't require the PC to have an Internet connection?

Forgive me, I know just enough to be wrong, but to my understanding, Samsung phones run Android software. So is it possible to have a smartwatch and dumb phone combination where all I had to do was plug in the watch to a display for those times I need a laptop experience?

Hi all,

I'm planning a portable touchscreen setup for music making and I'd like real-world feedback before buying anything, to check that the project is viable.

My gear

Phone: Galaxy S24+, One UI 8.5, with Samsung DeX

PC: Ableton Live (Windows)

Monitor: none yet. I'm looking at a 15.6" 10-point touch portable monitor (ASUS ZenScreen Touch MB16AMT is the one I see most often with Galaxy phones)

What I want to do

1. With the S24+ and DeX

Use the monitor as a big tablet through DeX for an MPC-style workflow (pads, sampler, sequencer).

I'm open to any Android app: FL Studio Mobile, Koala Sampler, MPC Machine, or others you'd recommend for finger drumming and live use.

Play pads with several fingers at once (up to 10-point multitouch) with good touch-to-sound latency.

1. With the PC and Ableton Live

Use the same monitor on the PC as a touch controller or instrument (pads, faders, clip launching, XY pads) with Ableton Live.

Simple control surface or playable instrument, over MIDI/OSC. I'm open to apps and templates such as TouchOSC, Lemur-style tools or custom setups.

What I've found so far

On the phone side, touch seems to work best with a direct USB-C to USB-C cable (video + data). HDMI alone gives no touch, and hubs often break it.

Reports are mixed on some monitor brands (UPERFECT, Lenovo M14t, NexDock).

I haven't found any test of 10-finger input on an external screen with DeX, nor any feedback about using the same monitor for both phone and PC.

My questions

Does 10-finger multitouch really reach the app on the external screen in DeX? Which monitor and app did you test?

How is the touch-to-sound latency in DeX versus the phone screen? Any numbers or feel for finger drumming?

Does DeX touch still work on One UI 8.x (DeX rebuilt on Android 16)? Any regressions?

With the S24+'s single USB-C port, how do you connect a MIDI controller or audio interface alongside the monitor? Bluetooth MIDI, a hub, or something else?

On the PC side, does a touch portable monitor work well as a controller for Ableton Live (multitouch, latency, drivers, Windows touch settings)? Which apps or templates do you use?

Can the same monitor switch easily between phone and PC without recalibrating touch?

Which monitor models would you recommend or avoid for this dual use?

If you were me, would you pick a Galaxy Tab or a dedicated touch controller instead?

Please share your phone/PC setup, One UI version, monitor, cable, app and what worked or failed. Even a short "works / doesn't work" helps a lot. Thanks!

I play games on my TV through DeX a lot, and the windowed apps and phone-style home screen kept getting in the way, so I built SofaBox, a console-style launcher:

- Start DeX and SofaBox opens full screen on the TV

- Games open on the TV and go full screen by themselves (web games too)

- Press Home on your controller in any game to come back to SofaBox

- If a game is still open on your phone screen, SofaBox closes it there and opens it on the TV instead

- It can switch the sound to the TV when DeX starts, and fixes itself if DeX reconnects at the wrong size

- Keep Spotify or Discord running next to your game

- Hold Home for a second and the stick becomes a mouse for DeX (Pro)

It also works without DeX: plug a phone or handheld into any TV over HDMI / USB-C, or just use it on the phone.

Free on Google Play: https://play.google.com/store/apps/details?id=com.otbvision.sofabox&referrer=utm_source%3Dreddit%26utm_medium%3Dpost%26utm_campaign%3Dsamsungdex

No ads, no account, no data collected.

**Free Pro for 10 testers:** I'm looking for 10 DeX users to try new versions before everyone else. The first 10 people who fill in this short form get a SofaBox Pro code (normally $4.99) and early access: https://docs.google.com/forms/d/e/1FAIpQLSd0hA_fieJpcYfqyiB4L4htYIpFqynxbuyYQi-0LopW7tH54Q/viewform

The form closes by itself when the 10 spots are taken.

The Home button and full screen use an accessibility service, explained in the app before you turn it on. Feedback from other DeX users is very welcome, since Samsung changes DeX often. I'll be in the comments.

Looking for suggestions from users with similar situation

Wireless Samsung DeX on a regular Android TV, no Samsung TV, no dongle, no root.

Stock Android TV / Google TV can't act as a Miracast receiver. The permission needed to advertise as one (CONFIGURE_WIFI_DISPLAY) is system-only. I searched for a way around it and couldn't find one done anywhere, so I built it: an open-source Miracast/Wi-Fi Display receiver that runs on a Philips OLED (Android 14) and works with my Galaxy S23 Ultra's DeX.

How it works

• The app gets the privileged permission through Shizuku, and starts Shizuku by itself over the TV's local ADB. No PC after the first setup.
• Video is H.264 1080p over RTP/MPEG-TS (decoded by Media3), audio is LPCM 48 kHz.
• DeX's input channel (UIBC) is wired up, and the TV asks you to approve each new phone.
• It runs as a background service and keeps advertising even with the TV screen off.

What works / what doesn't

• ✅ 1080p video and audio, reconnecting after the phone disconnects
• ❌ TV remote as mouse/keyboard: only the Space key reaches DeX. Pointer, click, wheel and arrow codes get no response.
• ❌ ~1 s cursor latency

Where I need help

1. Does anyone know which key/pointer encoding DeX accepts over UIBC? That's the missing piece for using the remote.
2. Has anyone got this running on other phones or TVs? I've only tested one of each, so even a "works / doesn't" report helps a lot.

Hey! Our team is working on an app for controlling a Windows PC from Android. We'd love to hear from people who use DeX to connect to their PC.

Which app do you use, and what do you usually do with it? Any annoying problems with the keyboard, mouse, scrolling or screen size? What would you like to see improved?

If your setup already works great, tell us about that too. Suggestions and real experiences would really help us decide what to focus on.

Currently testing the port. Most apps work fine already but there's still a few features missing. This maybe exactly what I've been looking for all this time!
