Hi @timothyber,
Thanks for reporting this issue.
Are you using the most recent spacedesk Driver and Viewer version?
We will check and try to reproduce it on our side.
What is the current quality/performance settings on your android viewer app?
Can you please tell us the current encoding type, custom fps and rendering color depth values?
Could you also please try to enable the auto-reconnect option on android viewer settings and check if it will help?
