The dex system is really, really good to be implemented.

It is totally my dream for having a dual screen output (phone + screen). The sad thing though, still no news for linux on galaxy.

Really waiting for the dex system to be impkemented on a older phone model.

The real sad thing for me is... the price...

On my region, Note 9 costs more than 2 months of my wage (and arond 6 times of minimum wage), so it is pretty expensive.

As excited as I am with Tab S4, since it'll cost more or less the same with Note 9 when we count the keyboard dock as well, it is kinda hard for me to grab one.

And, as you said, the real problem with Android tablet is android tablet's exosystem.

Really hope google is going to take a serious approach for that, as it not only helps android tablets, but their chromebooks as well.
[Samsung Galaxy S8+ Accessories] SC07 TP2:
Agreed. App suspension (never mind lack of keyboard/mouse button support in Fortnite) severely limits chromebooks as much as DeX and usefulness of the secondary screen (phone or tablet).

While I don't know for sure if Samsung's Android and DeX processes are separate but I'd wager that if I was to run my music app on the Note8 screen (MortPlayer) while its sitting in the docking station and direct my focus to the DeX desktop, the music app will probably not update the phone display while the music continues playing (much like now). Messaging apps may still pipe up notifications on DeX but the app on the phone display will most likely be static. :(

Looking forward to a demo of a Note9 hooked up to an HDMI dongle/display to find out!
[Samsung Galaxy S8+ Accessories] SC07 TP2:
Probably a deliberate design decision as they don't want keyboard/mouse users running rings around and wiping out the screen-only Android Fortnite players... This is the reason that console versions don't support USB keyboard/mouse and console players playing against PC players isn't an available option.
[Samsung Galaxy S8+ Accessories] StardustGeass:
Have you tried watching the samsung unpacked event?

If I remember it correctly, they show that when the note 9 is connected to the dock (and they mingle with the phone), the dex system on the screen seems to be dynamic.

If it is not there, I think it is one with the tab S4 advertising / hands on review that shows the capability.

So both of them will move.

But, again, it depends on the apps you use. MOst if the game does stop when the focus changed.

There is anyone that uses 21:9 monitors with the S9's Dex Pad?
[Samsung Galaxy S8+ Accessories] batmar333:
Does anyone know if note 8 works with Hp elite x3 docking station?
[Samsung Galaxy S8+ Accessories] StardustGeass:
Natively, only screen mirroring... If you want to activate its dex capability, need root and install custom kernel..

That, or Samsung suddenly feels like bringing note 9 dex optimization to older device.
[Samsung Galaxy S8+ Accessories] batmar333:
Thanks....what do you think about this https://youtu.be/wZh5fEbid5w
[Samsung Galaxy S8+ Accessories] StardustGeass:
Alright, that works as expected on note 9!

Sad I don't use lapdock right now (don't have any money to grab note 9)

Hi SmilerOnline - I've upgraded Desktop Hub to build v2.30 which has the following enhancement:

• Added Samsung DeX exclusive screensaver (doesn't run in phone mode to avoid screen burn in on AMOLED display).

Can you tell us how to activate this screensaver, please?
[Samsung Galaxy S8+ Accessories] Drewmk20:
i just bought a samsung dex (for the s8 note 8) and it gives power through usb but not through the main usb c in the middle ....i use a s9+ ...? any sugestions ?
[Samsung Galaxy S8+ Accessories] pimikiel:
What do you mean by usb-c in the middle? It doesn't charge your phone? There should be no middle. There is only usb-c input and usb-c output.
[Samsung Galaxy S8+ Accessories] Drewmk20:
the usb c where you plug in the phone (not the charge one) i see that when i plug in the fastcharger it has usb power (i can text with a mouse that will light up or a mini usb flashlight) but the center where you plug in the phone does nothing....
[Samsung Galaxy S8+ Accessories] StardustGeass:
So I assume you bought the Samsung dex dock? Not a dex pad or other 3rd party dex enabled adapters?

I'll try answering based on that assumption first.

I assume your question is, why is it shows USB charging instead of a fast charging one (even though you plug the fast charging one to the dock).

If that is your question, the answer is, because dex system somehow does not allow fast charging. I think it is related with the heat issue or something else. When you turn off the dex mode (using the dock/pad only for mirroring), IIRC, it fast charges again.
[Samsung Galaxy S8+ Accessories] Drewmk20:
I already bought the round dex dock for s8/s8+ and the output has no power over usb c. When i put the phone in, nothing will happen. I feel either i got ripped off since i bought it second hand for 35$ or it wont work with s9+ .
[Samsung Galaxy S8+ Accessories] StardustGeass:
"Nothing happens" as in not even charging at all?

Round dex dock will work on Samsung S9+.

Try to remove any case you use before plugging in. I remember that there are many case that causes the USB C to get plugged inappropriately and causes some error.

If you already plug the power adapter to the USB C on the back, HDMI to its proper slot, place the S9+ to the dock and nothing happens, you got a defective dock.
[Samsung Galaxy S8+ Accessories] SmilerOnline:
Settings > Display > Screensaver.

Enable the screensaver toggle and select the 'DeX screensaver' to enable the screensaver designed to only show in DeX mode.
[Samsung Galaxy S8+ Accessories] pimikiel:
It needs to be powered by genuine samsung quickcharger for s8 and higher. I have one from s8 box, one from dex box, and bought 3 additional ones (clamed as samsung quickcharger) and only boxed ones works with the dex. Other 3 charges phone, (one broke down after a while) but do not work with DeX

I know its nich, but it is unbelievable that no reviewer tested Dex

I want to buy the 8gb model because of dex

Hello guys,

When I running the Desktop Hub version 2.3 and desktop version 2.5.86 on S9+ mobile, if I enabled Desktop Hub shortcut via accessibility service, it works fine. But if I switch the Dex mode to mirror mode, then back to Dex mode, the Desktop Hub shortcut doesn't work. I will need to re-enable it via accessibility service. Any one encountered like this? Do you everytime enter the Dex mode, need to re-enable accessibility service for Desktop Hub?
[Samsung Galaxy S8+ Accessories] StardustGeass:
Hmm.. Personally I'm never able to test that, because I never change setting to screen mirroring..
[Samsung Galaxy S8+ Accessories] fordiy:
I meant accessibility service need to re-enable for Desktop Hub everytime I enter Dex mode.

If I quit the Dex mode, then re-enter Dex mode, the Desktop Hub gone, need to re-enable it via accessibility service.

I encounter accessibility service need to re-enable for Desktop Hub everytime I enter Dex mode.

If I quit the Dex mode, then re-enter Dex mode, the Desktop Hub gone, need to re-enable it via accessibility service.

How to solve this problem?
[Samsung Galaxy S8+ Accessories] SC07 TP2:
Here's the Note9 DeX review from Android Central https://m.androidcentral.com/samsung-dex-review-2018. Some of the criticisms can be addressed by enabling DeX Labs (the reviewer doesn't appear to have from the pictures associated with the article) or by installing Hancom Office which does allow multiple instances of word processor, spreadsheet, presentation and PDF viewer. Desktop Hub and the multitude of Meta key shortcuts make a significant improvement in user experience over vanilla DeX and I hope SmilerOnline continues to develop it.

I've not had any spontaneous app slowdowns or shutdowns with my Note8's 6GB memory so don't go the extra US$250 for the 2GB memory alone. Where it would make a difference is with the mythical Linux on DeX. Hard to believe that just coming up to 9 months, Samsung doesn't even have a Beta (Alpha even?) program to allow the enthusiastic DeX community to contribute to its' development.
[Samsung Galaxy S8+ Accessories] batmar333:
Do you guys think it will be possible to have Dex mode without need any special adapter (just like Note 9) in future with Note 8 and S8/9?
[Samsung Galaxy S8+ Accessories] StardustGeass:
It is clearly possible, as the dex system is actually on the phone instead of the docking hardware. Hardware-wise, I don't think S8 and note 9 have so many differences that makes it impossible. The only real problem is, whether Samsung will open that up.
[Samsung Galaxy S8+ Accessories] KenHua:
I'm using Desktop Hub version 2.3 and desktop version 2.5.84 (not 86) on S9+ and everything works fine. The accessibility service stayed active regardless of how I swtich: Dex to Mirror to Dex to Undock to Dex etc.
[Samsung Galaxy S8+ Accessories] xxaa:
Hardware wise... the cooling pipe is bigger on the note 9! For people wanting 4K from their mobile device, we could argue it's fare to restrict DEX on the others (for the humble users it's just sad).

Anyway for the lack of linux, I see 2 possibilities:

1° Mali'sdrivers were missing with GNUroot Debian, thermux and other linux flavor running in "a container" on android 7.1. But Samsung has already those driver so it could be a license problem.

2° Those linux flavor in "a container" can't run on android 8.0. Maybe Samsung face the same problem with the new kernel.
[Samsung Galaxy S8+ Accessories] SC07 TP2:
SmilerOnline is running a 2K desktop through the ADB tool but finds his S8+ slows down in games (not so much with his S9+) so I agree there may be an element of truth here.

Re Linux on Dex, again there may be an element of truth that Samsung have encountered technical barriers with Android Oreo in what they wish to achieve with Linux on DeX as is it more locked down than Nougat. Nougat was the prevalent Galaxy S8/S8+/Note8 OS at the time they announced it to the world at their Developer Conference in San Francisco last year. Oreo became available to the S8/S8+ and on new S9/S9+ from March 2018.

Presenting APIs to a standalone OS running within a container probably requires co-operation/permissions from the kernel that may no longer be available.

Considering the serious fanfare achieved at the start of the year, let's hope they haven't given up on it without at least a short public announcement or explanation to deflate the built-up expectation. Perhaps they'll have something to say at this year's developer conference in November?
[Samsung Galaxy S8+ Accessories] tonylmiller:
You will always need some kind of adapter, but it doesn't have to be Samsung. I use a cheapo USB dock with HDMI on my Galaxy S9 and it works just fine.

What would be REALLY nice is Dex over some kind of wireless screen cast. Along with a bluetooth mouse and keyboard, that would be sweet.
[Samsung Galaxy S8+ Accessories] SC07 TP2:
Samsung Galaxy phones already support the Miracast protocol (dongles and TVs that support screen mirroring) and there is an option to change to a 16:9 ratio image to completely fill the screen too. Samsung needs to allow users to switch to the DeX desktop on demand within software but they've not felt the urge so far... :(

Using a mouse/keyboard on a Miracast display is a bit laggy I'm afraid. Good for showing videos/pictures/presentations but not for text editing/games.
[Samsung Galaxy S8+ Accessories] StardustGeass:
Agreed!

Miracast is still a bit too laggy for me to use for document editing and games. For media consumption, it will perform very good. But again, what's the use of dex system if we only use it for watching media only?

Also, AFAIK, miracast so far can only support mirroring and not screen extending yet?
[Samsung Galaxy S8+ Accessories] daniel_cassian:
Can we use SPEN while in Dex mode. I mean to be able to write in Samsung Notes (or a 3rd party app) and see the results on screen while in dex mode. We can do it in mirroring mode...but I'd rather be in dex
[Samsung Galaxy S8+ Accessories] StardustGeass:
AFAIK, in your case, no. I haven't seen any app that offers that kind of feature. The only one I know, is when you play a PowerPoint slide, and then you write on the slide on the phone.. The writing will be displayed on the display as well..
[Samsung Galaxy S8+ Accessories] SmilerOnline:
Adobe Sketch allows you to display a full canvas on DeX while the phone has a zoomable canvas
[Samsung Galaxy S8+ Accessories] StardustGeass:
Oh! That's really nice!! Thanks for sharing!!
[Samsung Galaxy S8+ Accessories] daniel_cassian:
As we all know it is said that with the new Note 9 we no longer need a Samsung dex dock but instead we can use an USB c adaptor to HDMI; so I thought to myself why not go for a long cable instead of a short adaptor.

I found this: USB C to HDMI Cable(4K@60Hz), 3.9ft USB Type-C to HDMI Braided Cable

and I was very happy about it. I did write the seller asking him whether he knows if it will work with Note 9 for the dex mode and to my surprise he replied that it will not.

Any thoughts on this? can I use a long braided cable capable of outputting 4K at 60hz with my phone to enter dex mode?

If you are wondering why the hell would I need something like this I want to point out that now we can use the phone while it is in dex mode I would like to work on it from home standing on my sofa connected to my TV which is 3 m away from me. to connect this with my previous comment I would like to be able to write with my pen on the phone but to have an output on the TV that I need something to connect my phone to my TV 3M away and unfortunately mirroring screen is not an option due to the narrow image
[Samsung Galaxy S8+ Accessories] StardustGeass:
I'm guessing the seller doesn't understand about Samsung DeX system on Note 9. But, here's a catch... the longer your cable is, the more fragile connection you will have because longer cable have more resistance..

For instance, when I use a longer cable on my adapter, the screen sometimes stuttering or even resets DeX mode. When I change to a shorter one, it never happens again.

Well, perhaps the cable quality takes place as well (I'm using a less than 1$ hdmi cable), so perhaps it cause the stuttering. But, for now, I'm stick on using a shorter one...

Rather than a longer cable, perhaps you could use a wireless hdmi connector? I remember unbox therapy on YT once reviewed it, and even when connected to a Nintendo switch with a more than 5 m distance, it shows no noticable lag at all..

Anyone tried 3rd party Dex station for s8 plus with Oreo update on it?

I bought a Melopow Dex station but its not working on Oreo only in Nougat OS only.

any idea how to use it on the Oreo ? or any Rom suggestion?

Thanks
[Samsung Galaxy S8+ Accessories] bmszabo:
I have a cheap, ebay 3d party Dex station - and it works fine on Oreo..

[Samsung Galaxy S8+ Accessories] kbarni:
Dex is working on third party adaptors with custom kernels (Nox, Notorious etc.) without problems.

Renovate Ice and Alexis ROMs (and maybe others) are using Nox kernel, so they have Dex support out of the box.

Just a thing: on Oreo you'll need to connect a charger to the adapter, otherwise Dex won't work.
[Samsung Galaxy S8+ Accessories] maxnik1:
You have to connect your power adapter (the one that came with the phone) to the Melopow. Since Oreo, DeX requires power source.
[Samsung Galaxy S8+ Accessories] SmilerOnline:
USB-PD chargers work too! :)

PD = Power Delivery.

I typically use the PD adapters capable of 65w output or higher.

I know it may be overkill, but at least I know that it can power all of my USB Type-C devices.

* I'm trying to switch everything I can to USB-C powered as I think that is the future and its less likely to have problems when moving to a different country.

Anyway yeah, I'd suggest that if you need DeX compatible power adapters, just search amazon for 'USB-PD' (or somewhere else of course).
[Samsung Galaxy S8+ Accessories] cyke0213:
Nothings happen

I already tried that but nothing happen.

It charge my phone only normaly.

I think the Device Melopow is defective?

I bought it online.

If you have screen mirroring when connected, than it should work. What ROM and kernel are you using (and version)?

Using S9 in Dex dock generation 1, with Samsung 5100 mAh powerbank. Also Samsung T1 SSD connected and Bluetooth keyboard and logitech mouse. =)

All connected to JmGO P2 View projector.
[Samsung Galaxy S8+ Accessories] daniel_cassian:
I am wathcing on YT now a video explaining things to do with Dex and Im completly upset by one thing. This guy here uses Note 9 with the new dock (dex pad). I have the 1st generation and a melopow 3rd party usb c hdmi adapter.

As you can see from the screenshot i attached, he has an option to control the mouse and even write using his spen while in "use your phone as a touchpad" mode. I even highlighted the option to use finger OR spen.

I dont have that "with finger or Spen".... just "tap here to open the touchpad".... and obviously i cant control anything with my pen. What are the chances this is due to a new feature of the dex pad??

When i pull out my spen ... i do get a grey message (that dissapears fast) with "swtich to landscape to use spen while in dex" ... and i press on the up right circle twice to switch the "touchpad" in landscape mode... but spen still not working.

Anyone .. any thoughts into this matter. To me it is very important to get this to work. As OP recommended i use now Adobe Sketch so i can use my spen and see it on a tv while in dex, but it does have its shortomings.

From what i see in this tutorial... i could use the spen wherever i want.... even as a mouse.View attachment 4591594
[Samsung Galaxy S8+ Accessories] SmilerOnline:
The Note 9 S-Pen mode works in a way more aimed at designers where you touch a specific part of the phone display and it shows the pointer at the exact same location (respectively) on the external display, to move you have to hover the pen closely or press and move to move the pointer, so a digital designer can get something that feels like a Wacom input device.
[Samsung Galaxy S8+ Accessories] daniel_cassian:
https://youtu.be/rfiFitSrcvk

This video explains better. I dont have on my Note 9 the feature to control the touchpad with my Spen. Wanted to know if it is because i use the dex dock (1st gen) or 3rd party hub.

He uses spen as a mouse and writes in any app visible on dex
[Samsung Galaxy S8+ Accessories] daniel_cassian:
Screenshot with black background is mine. The one with white background is the YouTuber's. Notice the "tap here to open the touchpad" on my phone and his "Control Samsung Dex using your finger or S Pen"

I even contacted Samsung support, unfortunately the dude there doesn't know on what planet he is.... Didn't understand at all what i asked. He said Dex mode doesn't work with Dex dock...lol...i am in the dock and it's working...all but that feature where you can control the dex with the Spen.

It requires the device to be seated landscape to work, so I suspect that you are having issues because the original station only allows the device to be seated portrait.
[Samsung Galaxy S8+ Accessories] dorsefrith:
Hello all.

It was some time since I was here :) good to see that you have new ideas how to use Dex. I was thinking lately is it possible to use ear Vr controller as a a mouse. For example if I connect it to the phone and it could somehow track hand movement, you could use it as a "mouse". Then you connect dex to projector,sit on a couch and navigate all with a controller. I know that it would need some development but is it possible?

Best Regards.
[Samsung Galaxy S8+ Accessories] daniel_cassian:
I also have the same issue with the meopolow 3rd party hub, which allows me to keep it in landscape mode...still no go.

I managed to do a remote session with a Samsung rep today. He was more open to my issue, he took note, saw my screenshots said he will forward this to someone above him as he didn't know why this happens.

On top of my current dex issue just found another. I discovered that in my Note 9, if i use dex hub it will render my keyboard off. I have 4 keyboards (Microsoft arc, a Bluetooth Motorola l, a Bluetooth Myira and a Logitech kit on usb wireless). If i connect them and use them is all fine.... But...if i open the dex hub...in about 10 seconds the keyboards won't work anymore. With the usb ones had to restart phone to make them work again...with the Bluetooth ones had to connect\disconnect several times (5+) until they decide to work again. I'm on the August 2018 Android update. Mouses on the other hand have no issue !!?
[Samsung Galaxy S8+ Accessories] SC07 TP2:
DeX knows it is there but doesn't consider it an active Bluetooth device - Gear VR Controller(26FC) remains greyed out within the Bluetooth panel. Left-clicking on it and selecting 'Recalibrate' from the options menu will guide you through the calibration process drawing figures of eight in the air until it has captured a consistent pattern before asking you to place it face down on a flat surface.

The Oculus icon shows up on the task bar which indicates that it was the Oculus software that was talking to the controller. It can detect movement and orientation of the controller in space but they haven't implemented Bluetooth mouse pointer driver support or any button support as even the volume up/down buttons don't work.

Interestingly DeX natively supports Bluetooth graphic tablets! I have an old Wacom Smart Slate WS200 and hovering the pen moves the mouse pointer, tapping the surface does the left click, you can drag the pen tip to select text and the pen button is the right mouse button.

I guess we need Oculus (Facebook) to extend their Bluetooth driver to support mouse pointer control but the Bluetooth tablet support demonstrates it is available inside the Android kernel.
[Samsung Galaxy S8+ Accessories] StardustGeass:
DeX hub you mean original DeX station? Or desktop hub in apps?

Well, whichever you meant, have no problem with them.

I'm not currently using one with my note 9 (sold the hub already months ago), but I remember I have no issues with bluetooth/ USB keyboard and or mouse when I use it with my S8.

I'm using note 9 quite intensive as well with my 3rd party adaptor and desktop hub app. having no such issues..
