Black screen on secondary Android, USB connection

#1 · 20/10/2025, 13:45

Updated to the latest drivers on both my Primary (Win11) and Secondary (Android) devices.

I had previously connected successfully using USB.

It no longer works. The Secondary device seems to recognises the connection (but just shows a black screen), but the Primary device does not detect the monitor.

Using wifi it works, but this is not a viable permanent solution.

I have tried changing every setting I can find, with no success (and not much of a clue what I am doing).

What next please?

Hi @scargy,

This is a known issue with Android USB when using USB 3.0 cables or higher. If you have a USB 2.0 cable, can you try using that to connect via USB? Also, for further analysis of the issue, 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 via USB.
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.

Thanks.

I don’t think the cable is the issue – it was a very old one (pre-USB3.0), and I’ve replaced it with another of similar vintage. No change.

Diagnostics logs attached.

Hi @scargy,

From checking your logs, we did not see any connection being established. Please try to follow the steps I previously provided again, now making sure that you connect via USB (even if it’s not successful) so we could analyze the issue further. Thanks!

OK, I’ve tried again.

From the Secondary device it seems that a connection is detected (screen turns black when the cable is inserted), but the Primary device does not detect an additional display.

Hi @scargy,

You sent the same logs as the previous one you sent. Please send another where you attempt to connect via USB. Thank you.

Hi @scargy,

Thank you for sending your logs. When spacedesk USB Cable Android is turned off in the spacedesk Driver Console, can you access your Android tablet’s files via USB?
