Black Screen on Secondary Device (Samsung Android 11 Phone)

I have been using spacedesk for a couple of years now and I am happy that I found this software. I am glad that there are people making this possible but I have experienced just today after I updated the app that when I connect to my phone it shows "Connected - Display Off" then it disappears and has a black screen. I waited for a couple of minutes but it still didn't show anything. I tried to switch the display mode to "Show on 2nd screen only" and it showed "COnnected - Display off" again. I hope there is a fix from this... I tried to restart my phone. Restart my laptop. Uninstall the app from my phone and it still didn't work. I tried to turn off my wifi and turn it back on and it still would not work.

Hi @lifetime,

While it's black screen on the viewer app, did you find the spacedesk display on the display settings on primary machine?
Does the spacedesk SERVER window shows any indicator that there's a viewer connected (e.g. connection count or in network connections (remote) tab) ?

Did you update to our most recent spacedesk Driver v0.9.99?
If not yet, please update and check if you still get the same issue.

In case the problem still persist, could you please send us the following info:
Primary Machine
- operating system (Windows 8.1/10)?
- graphics adapter (AMD/Intel/Nvidia)
- network connection type (wired/wireless/USB tethering/WiFi Direct)

Secondary Machine
- Viewer type (Android/iOS/Windows/HTML5)
- network connection type (wired/wireless/USB tethering/WiFi Direct)

hey! @spacedesklea thank you for replying to my concern. The spacedesk window appears and it shows that it has "Connections: 1" and I can see my device in the "Netwrok Connections (Remote)"

Yes, I have updated the software to the latest version of spacedesk. My laptop is Windows 10 and has an AMD Graphics Adapter and I just connected it to my wifi via an ethernet cable removed link For my secondary machine, it is Android 11, and I connected it to the same wifi router removed link

Hi @lifetime,
Thanks for the feedback.

I can see my device in the "Netwrok Connections (Remote)"

Is it attached or detached?

Can you  also quickly try to connect via HTML5 Viewer on the same android 11 phone ?
Just open a web browser e.g Google Chrome then go to http://viewer.spacedesk.net/ and connect to the IP address of your primary machine.
Then let us know if you still have the same black screen issue.

Hi @spacedesklea thank you for assisting me. In the Network Connections (Remote) it says it's attached (extended) and when I tried to use the HTML 5 Viewer as you said but the problem still persists and it is also stated in the software in the Network Connections remote "attached (extended)".

Hi @lifetime,
Thanks for quickly trying it.

To further analyze this issue, please download the spacedesk diagnostic script here, then extract it.
https://www.dropbox.com/s/z8h5llgi8c2ig3g/2021_spacedeskDiagnosticTool.zip?dl=0

Inside you will find spacedeskDiagnosticTool.cmd, just right-click it then run as administrator.
This script will start a debug view app to capture spacedesk debug traces.
On step 5 it will prompt you to reproduce the issue (by connecting the viewer app and wait for the issue to happen), make sure to do this before pressing any key to continue.
After the script is done, a folder will be created on the same folder as the script file which contains various log files that we need for analysis.
Please right-click it -> Send to -> Compressed (zipped) folder, then attach the *.zip file on your next reply.
