Black screen
Samsung tab A7 running one ui 4.1 shows a black screen right after opening the app despite not being connected to PC and is not detected by the primary server. I tested it on another phone and it works perfectly fine. I believe the tablet connects to literally nothing as I can’t even open the app in airplane mode while unplugged without getting a black screen and tapping the disconnect button closes the app entirely.
Hi @omar-2,
Please try the following steps on your spacedesk viewer:
1. Go to Settings > Quality/Performance
2. Click on Encoding Type, then select Software Encoding (forced)
If this does not resolve your issue, please send us your logs by opening the spacedesk Driver console as administrator and clicking on Diagnostics then follow the steps below:
1. Download the DebugView.
2. Check the Diagnostic Collection box.
3. Reproduce the issue e.g. by connecting the spacedesk Viewer app.
4. Uncheck the Diagnostic Collection box.
5. Click “Save All Information” button (this might take a while to finish).
6. Compress/Zip the folder which contains the logs, then attach to your next reply to this post. If the folder exceeds 512kb, you may upload it to Dropbox or Google Drive then include the download link on your next reply.
Thank you.
Just a tip for anyone still struggling:
The settings button in Spacedesk Viewer is hidden behind the three dots (…) in the green bar, top-right corner, before connecting to the Primary Machine (server).
These dots are not very visible, so it’s easy to miss them.
In there you can change Encoding Type → set it to Software Encoding JPEG (force always).
That fixed my black screen immediately after days of troubleshooting.

It might be a compatibility issue with Samsung Galaxy Tab A7 on One UI 4.1. Try clearing the app cache/data, reinstalling the app, or running it in Safe Mode to see if another app is conflicting. Have you checked if the app has the needed permissions enabled?
