Admittedly, I haven't tested the Samsung keyboard, one of the first things I did when I got the S8 was switch to the Gboard, just because it contains all of the info it collected from my previous devices (including the custom dictionary).
Thanks for the reply another question what's the impact with battery changing the DP setting if any, also using dex quite regular with office 365 would this in any way have a longer term impact in battery as constantly charging

@SmilerOnline, I'm glad to find someone else that is as excited about the DeX dock as I am. This is absolutely the future and I've got a feeling that with Android being the first to "get it right" we're going to be having Android vs Windows vs Mac debates in the near future.

Hi, guys.
I'm read your posts and I hope I can help you little more. I own DeX and USB-C to HDMI cable. I made debugg log when mobile phone is connecting to SmartTV and I was trying to change Mirroring mode to DeX.

I cant really answer that as I haven't really ever noticed any changes on any device I have ever changed the DPI on, I just generally haven't been worrying about the impact on battery life.
As long as the device can last me 18 hours on a single charge I have never really let myself get distracted by the battery life issue...
Battery life anxiety is becoming a real mental health issue that I think people should visit the doctor for... :rolleyes: lol.
But seriously, it can't be very significant.
@NicksOnTheWing:

Great to see someone showing their positivity for the industry moving forward in this way! :)

Anybody tried a USB C DP adapter? I connected it both to a active DP-DVI adapter and a passive DP-HDMI adapter. No success so far.
I don't know what standards that adapter you have linked to uses (MHL/SlimPort/DisplayLink etc), but I have a SlimPort adapter which I have tried (Type-C - HDMI) and it just screen mirrors, no DeX support though...


*USAGE UPDATE*
I am currently typing this up on my Windows 10 laptop and damn it makes me appreciate DeX even more, as this laptop stutters on scrolling XDA forums, but it is always smooth on the S8+ & DeX.

I have put together this free(and ad free) app for DeX users (Dex Hub).

It simply lets you choose whether your device automatically turns on/off Wi-Fi & Bluetooth when going in and out of DeX mode.

It plays start & exit sounds to confirm when it has ran the script.

It also has a device resources and background services monitor for those of you with performance concerns when in DeX mode:

Dex Hub - Play store link

Normally I would charge for apps (ads just didn't generate enough revenue), but this is free as I want to encourage the adoption of Unified Computing, yeah it is nothing special, but it is just designed to remove the need to change settings continuously and reduce anxieties of those who think that the S8 doesn't have the horsepower to do what they want.
I may add more features in the future if it can help to encourage more people to use the DeX mode.
There is a donate button in the overflow menu if you want to support development, but there isn't any need to as everything is available to all users.

I set up my DeX at the weekend with a new 23" screen and wanted to make sure that one of the Turbo Trainer Cycling software apps works. After thinking that none of them would work, I got Bkool to work, but it said it was only for touch screens - so would not open in DeX. Until, I saw the mirror screen option.

It works perfectly with that (well I have not tried hooking up the ANT+ or Bluetooth) but the screen was great and even though it said it was only for touch screens I could use my mouse as well.

Anyway the point being that the app worked full screen which is what I wanted by using screen mirroring, which I suppose might be a solution for Plex etc.

Does kodi work properly and in full screen on dex?
Not yet... Though I did post instructions to add support on their forums, wether they will take note or not remains to be seen...

The topic has had no responses so I can't imagine that they'll pay much attention to it...
http://forum.kodi.tv/showthread.php?tid=312980

But it does work in fixed windowed mode if you want to watch content in a window

*'Non-DeX-Dock' 'Dex-Mode' discussion update*
When looking at the runing services in the Dex Hub app, I see that there is a different launcher running, and when I was previously researching how to detect the launch of DeX mode, I noticed that there was a 'Package_Changed' system broadcast... I wonder if the system is litterally removing the phone launcher from a folder and inserting the desktop launcher whilst the screen is black when docking/undocking...

The desktop launcher package is:
'com.sec.android.app.desktoplauncher'
The mobile launcher package is:
'com.sec.android.app.launcher'

Maybe there is something that can be done with these to switch to DeX manually via an app?
Though I suspect that this uses a secure system app to change the packages making it difficult to trigger this from a third party app.
But I'm just guessing at this point, I could be entirely wrong...
Just thought I'd add some info that may be of use to the guys trying to hack the S8 to enable DeX without the dock!

That is the Samsung Dex Home apk, or KnoxDesktopLauncher.apk. I and others have tried tricking it to run, plugged in HDMI adapter with hardwire keyboard and mouse, tried bluetooth keyboard and mouse, power hooked up as well.

Even with all of that, it simply won't run. It doesn't even try to and error out, it just won't budge. Haven't had time but want to run a logcat and see if I can catch what it's looking for and missing when it tries to run.

What I don't think we have had happen, is someone whose already run Dex try and see if they can run Dex with an HDMI adapter manually. It could be it downloads some file after you own a Dex to run, that isn't there before hand. Or it might authorize every single time. Haven't a clue yet.

Other thought is to rip out that APK and tear it down and see if I can find what it uses to launch.

Hopefully I get time later to reinstall some stuff on my desktop and do some logging. I've not done any of this stuff in a few years now so i am a little rusty :)

As I mentioned earlier, today I tried my SlimPort Type-C to HDMI adapter, and it just mirrors the screen, so it can't be that it installs something when the dock is first connected.

Good luck though! :)

*NOTE*
Just to add, I tried the following code in a custom app when in phone mode but no luck :( it just crashes the app I made... I'll look at the logcat later to see if I can discover why, but I'm busy over the next few hours :(
Intent LaunchIntent = getPackageManager().getLaunchIntentForPackage("com.sec.android.app.desktoplauncher");
startActivity(LaunchIntent);

Can you download Shortcut Master (lite is fine) in the play store and open it, hit the elipses, chose app explorer and make sure it's on system apps then scroll down to Samsung Dex Home and try and run the launcher? Hooked up to your adapter of course. That will manually try and force dex to run.

Other thing to look at, is under your Settings -> connections -> more connection settings, do you have HDMI settings? Seems for most once you use a Dex, it opens HDMI settings that we don't get else wise. You have an option to chose dex here. May or may not need to be connected to the HDMI adapter first to see these settings. I am not sure.

Now that a few people have had the Dex dock for about a week what do you think of it?

Specifically:
1.) Is there enough power? Does it stutter at all?
2.) is 4 GB of RAM enough? How many tabs can you have open? Have you tried running a big Excel Spread sheet
3.) How hot does the device get? Could it be impacting the devices health?
4.) Citrix Receiver, has anyone used an MVD on it? How's the performance?
4.) What do you use it for most often? I have a laptop and a desktop already why would having a Dex as well be useful?

Just curious to see what user think of it. I love the idea, but am just not sure there is a need right now. thanks for any feedback.
