Connect the window change to the launch event
Note which apps are open in the current desktop and which one was opened earliest. Observe whether the video window minimises when the next application starts, while its taskbar entry remains. This is a different result from an application closing or a programme reporting a playback error.
Samsung’s One UI 8 FAQ describes automatic minimising of the longest-open app when more than five apps are run. Its Australian product page qualifies newer workspace features by software version. Keep the actual model, software and desktop context with the comparison.
Compare a less crowded desktop
Restore the video window and make a deliberate comparison with fewer simultaneous app windows. Save unsaved work before closing another app. The useful observation is whether the same launch-triggered minimising stops when the desktop is below its documented limit.
Do not assume that a minimised window means its programme is still playing. The media application can have its own behaviour when hidden or in the background. Record the window state and the actual playback state separately, including whether sound continues or the application shows a pause when restored.
Plan the viewing workspace
Use the supported desktop or workspace controls for the installed version to keep the intended viewing arrangement manageable. Another software release may have a different presentation, so a tutorial’s exact app layout is less useful than identifying the current desktop and its open applications.
For help, report the Galaxy model, One UI version, app order, launch action and restored playback result. Keep network performance and service sign-in observations separate unless they also fail. This gives a precise window-management explanation for a repeatable launch event and prevents a functioning stream from being diagnosed only through a desktop limit.
