Native mouse and keyboard suport and graphics, running on a s23

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!

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.

Thanks for your support

I need help using Dex (or any other method) on my laptop. I mostly want to play games (native and emulated). I could also view photos and videos and run some other apps but it's mainly to play games now.

Bonjour

Il n'existe un moyen pour Dex sur A56 ou pas possible ?

Merci

Hi there!

I'm looking for a device that I can plug to HDMI TV in Airbnb, and use dex wirelessly with it.

For browsing, media streaming, while keeping my phone near me.

What device can you recommend ?

I don't have a need for this but I'm just curious 😄

Is it possible to access Samsung DeX, ideally without it actually connected to a display, via RDP or similar protocols?

I am using STRIFF 3-in-1 Type-C Multiport Adapter

Hey everyone! I'm currently running into the usual One UI kernel limitation where custom hubs kill the battery bypass (pass_through = 1) when trying to game using a mobilador (keyboard/mouse mapper) and Samsung DeX simultaneously.

I'm planning to buy the ASUS ROG Gaming Charger Dock (65W) to fix this, routing my peripherals through a secondary hub connected to the dock's USB-A port.

Has anyone here tested this exact setup? Does the ROG dock reliably maintain the PPS handshake required for the kernel to keep battery bypass active on One UI 8.5 / 9? Any tips or recommendations for a solid DeX + gaming setup would be greatly appreciated!

Hi,

I have a cheap keyboard to my Dex, but it's horrible at typing. Sometimes it makes double space and often it doesn't write the letter I press. Is this a normal thing or should I go for another keyboard? This one is bluetooth and connected to my phone. My phone is connected to a mobile screen by USB C cable.

Note: English is not my first language, so I used AI to help with the wording and translation. DX Manager itself was designed, developed, and tested by me.

Hi everyone! A few people requested higher frame rates, especially for gaming, so I’ve added an experimental 120 FPS option to the Microsoft Store edition of DX Manager.

For a detailed overview of DX Manager’s features, please check out my previous Reddit post:

https://www.reddit.com/r/SamsungDex/comments/1x2uvzi/dx_manager_is_now_on_the_microsoft_store/

What’s new

• Experimental maximum 120 FPS for DeX and single-window modes. The default remains 60 FPS.
• Selecting 120 FPS disables phone screen-off. Switching back to 30/60 FPS restores your previous setting.
• A heat, battery consumption and OLED burn-in warning appears before every 120 FPS start.
• Updated the bundled scrcpy to 5.0.1, including hardware-decoding fixes.
• Added built-in English/Korean release notes, shown once after an update.

Is it actually running near 120 FPS?

I tested VRChat on my Galaxy S26 Ultra running One UI 9.0 and checked a recording of the actual video stream.

A 30-second gameplay segment averaged 116.3 FPS. Frame-by-frame inspection of a moving scene also confirmed new game frames—not simply a 60 FPS sequence duplicated twice.

That confirms genuine high-frame-rate operation in this tested setup, but it does not guarantee a constant 120 FPS or the same results on every device and game.

To see the extra frames, make sure your PC monitor supports 120 Hz or higher and is actually configured to use it.

The phone screen must stay on. On my device, turning it off drops the stream to around 60 FPS. Turning it back on allows the frame rate to return toward 120 FPS.

Important: DeX window-dragging issue on One UI 9.0

I confirmed this issue on my Galaxy S26 Ultra running One UI 9.0: with HID mouse disabled, dragging an Android app’s title bar inside DeX can cause a black screen or freeze the entire phone.

The exact cause of the SDK-mouse/DeX interaction is still unconfirmed, and I don’t currently have a reliable fix.

For DeX, please keep HID mouse enabled. Do not deliberately reproduce this issue—it can leave the phone unresponsive.

This concerns app windows inside DeX, not moving the outer scrcpy window on your Windows desktop.

For gaming, I recommend trying single-window mode, particularly if a game’s controls work better with HID mouse disabled. In my setup, the game fills its own virtual display, avoiding the in-DeX title-bar dragging that triggered this issue. This is a workaround for that particular operation, not a guarantee against every possible crash.

The Android taskbar may still remain visible even when the game fills the window.

Useful shortcuts

Open DX Manager’s Session Log from Settings, then click inside the scrcpy window:

• Left Alt + I: toggle the current scrcpy FPS counter in the log.
• Left Alt + O: turn the phone screen off while keeping the stream running.
• Left Alt + Shift + O: turn the phone screen back on.

Remember that turning the phone screen off drops high-FPS operation on my tested device. These are the default scrcpy shortcuts.

120 FPS noticeably increases phone heat and battery consumption. Avoid prolonged or unattended use, be mindful of OLED burn-in, and stop if the phone overheats.

Thanks to everyone who suggested features, tested the app and shared feedback!

Mi s22 se me callo y no me funciona el táctil así que investigue y vi que se le podía conectar un mause con un adaptador OTG pero cuando pruebo en el teléfono me pide desbloquear para que pueda usarlo, así que me preguntaba si hay alguna forma de hacer que me deje usar el Mause sin desbloquear primero o si hay otra forma de recuperar lo que tengo en el.

Y si no hay forma y lo reseteo agarra el ratón en la parte de configuración cuando no tiene nada?

Took the photo using the phone from which DeX is being projected, so couldn't show the touchpad
