Not working properly
Zitat von Adrian am 05/01/2026, 20:39 UhrHello SpaceDesk Team,
I am writing to report a serious issue I have been experiencing with your application over the past two days.
Recently, I purchased the Business License (15,72 Euro). Before buying the license, SpaceDesk worked perfectly on my Samsung Galaxy Tab A7 (T505), which I use as a secondary monitor for my PC. However, immediately after activating the licensed version, the application stopped working properly.
I tried connecting the tablet using both USB and Wi-Fi, but neither method worked. I restarted both my PC and tablet, changed the USB port and cable, but the issue persisted.
Later, I tried connecting my Samsung Galaxy S23+ phone via USB, and surprisingly, it worked. After that, I reinstalled the Samsung USB drivers on my PC. Unfortunately, this made the situation worse:
• USB connection no longer works at all with my tablet
• Wi-Fi connection works only on my phone and Chromebook, not on the tablet
When I connect the tablet via USB, it only shows a black screen.
When I try to connect via Wi-Fi, I receive the error message:
“Connection failure – Unable to connect.”At that point, I honestly did not know what else to do.
Is there any way to fix this issue? SpaceDesk is extremely useful for me as a student and as a secondary monitor, especially considering the price I paid for the license.
Thank you very much for your time. I am looking forward to your response.

Samsung USB driver is incompatible with the spacedesk USB Driver so in order to use spacedesk via USB, you need to uninstall the Samsung USB driver, reboot, then try connecting again via USB. As for the issue with your Samsung Galaxy Tab A7, please send us the logs of your Primary PC 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.
