DEX Crashes Immediately Everytime Connected to Phone

[radiikal]

Hi,
I have a question regarding DEX...

My Note 10+, Windows 10, DEX and samsung USB driver are up tp date. Everytime i connect, DEX launches on my PC, i get the notification in my phone that DEX is running. However, in my pc, DEX will just shut down immediately after connected. This had happened since i received the phone after it was launched in my country. Initially DEX was able to run, occasionally. All i need to do is to restart my PC, and DEX will be able to connect. However, after the 2nd phone update, I'm unable to use DEX anymore. I used the original samsung cable and a few other cables to connect to PC, USB C to USB 2 type, tried them on all available ports in my PC.

Additional Steps other than updating phone and DEX that i had taken to try to resolve the issue:
1. Clear phone cache
2. Restart pc and phone
3. Change cable
4. Google (unable to find similar issue)
5. Search through samsung FAQ.
6. Searched in this forum.

Any help will be much appreciated.

Thanks in advance...

Dex was working for me ever since i got my Note 10 +
months back (launch dateAug / October ..? ) with my Lenovo laptop.
However a few day back, i got a notification to update Dex.
(I have done a few Dex updates.) No issues.


Done the update and now basically have the same issues as you.
Launch Dex.... does not launch..
Notifications on my phone Dex running...

Bottom line,
I'm sure it has to be a Dex bug..... software .!
I did not even attempt to investigate, as all Dex was working 100.%
Just waiting for the next Dex update.

My phone companion which was always buggy, is now working fine.
Good luck

Just an update , to my post above .
I again , downloaded the "Dex exe "from the official Samsung site .
https://www.samsung.com/za/apps/samsung-dex/
Then "ran/launched " the exe , that then prompted me to completely ,uninstalled Dex on my laptop .
After uninstall ,i again ran the exe to install .
I did not have to install anything else eg ..drivers again .
Dex is now working ( launching ) ) on my laptop .!

Secondly/alternatively ,
have you connected you phone ,to just a capable tv /monitor and launched Dex this alternative way , is " that method" working , for you ...??
Good luck .

 

[radiikal]

I'll try your method and report back.

As for 2nd method, i had only tried to connect to the usb hub that came with my monitor (and of course the usual usb ports on the motherboard ). So far it's a no go.

Thanks for the suggestions and hope it will work.

Much love!

Some additional questions, Maybe it can help...?
Does Dex work, if you connect with cable to only a eg tv screen.?
I just tested my device,
connected my device with HDMI/USB C to a tv screen and working fine..?

Is your pc /laptop, anti-virus may not killing Dex..?
Or your Note 10 device anti virus killing it ....
if you have any installed on device.?

Have you maybe disabled any apps eg with Package Disabler etc and now hav a knock on effect.?
Can you check with someone near you or local forums
to see if Dex is working for them.?( If they have any issues.)

Is Dex not maybe blocked by service provider.?
If Dex shuts down, does it pop up any "toast texts"? before shutting down?
If it does install a any "Toast " app form Play store
eg "Toast Source" app works fine for me. to "catch"
the toast popup, so that you can read reason for shutting down.

Question is according to you,
Dex starts, but is killed by either
the Device System or a 3rd party app?

Yes "something" eg app, anti virus etc is killing Dex,
as you are able to install Dex fine etc...... until launching Dex.!
Then Dex gets killed by.....?
Look for the culprit /app thats killing Dex..!
I can imagine this must be very frustrating for you !
Good luck

I've had the same issue for a every now and then. The fastest and easiest way I found to fix this is to pull the shortcuts and notification down There should be a small notification "Android System" USB for file transfer. tap this and change the USB mode to something else and then change it back to file transfer. This should allow Dex to see the phone or the phone see the PC again. Hope this helps!

Hello,
Can you try to update the Dex app with aptoide ?
Do you use CCSWE and you deactivated a service related to Dex ?

 

[saurabhsun]

I had similar issue, it doesnt work if Samsung Keyboard is disabled

I had similar issue, it doesnt work if Samsung Keyboard is disabled

THIS! Re-enabling the Samsung Keyboard stopped DEX from crashing. Thank you, it's been driving me crazy!

I've tryed another USB port and it work fine.

Turn off Link to Windows. This happened to me yesterday. On the second try I say a very brief pop up on my phone telling me to turn off Link to Windows.

As soon as I did that it worked fine.

You may have to turn off "Link to windows" on your phone first.

I got the Samsung Note 10+.

i have been trying to troubleshoot this same problem for the longest time, where i connect my phone from usb-c to my pc, press start now on phone and samsung dex will just close immediately.

finally today i went to the my phone setting, searched for "dex" and saw "Samsung DeX" under "Advanced features".

This is my first time going into "Advanced features" and I noticed many settings were turn off here.

So i turn on "Samsung DeX" and it seemed to have worked!!! I press start now and the connection went ahead to my pc and samsung dex started loading with the UI. I have not seen this app for a long time.

Now the question on why is it turn off by default? I don't know. I was able to connect to samsung dex on pc without problems.

i tried again and it didn't work! so i had to trial and error again. i can't do the normal unplug and re-plug in usb and press start now because samsung dex will exit immediately like before.

I had to plug in usb and then press the Samsung DeX to turn it on in my settings and it worked again. I don't know why it has to be this way.

I also went ahead and turn on Link to Windows, Call & text on other devices, Continue apps on other devices as well. Just because I want to use all these features when I connect my phone to pc.

hope this helps anyone with similar situation
