Force stop is a platform operation that stops an application's running activity rather than only leaving its screen. It can help restart an app that is stuck or behaving unexpectedly. Its availability and exact effects depend on the operating system, and it should be distinguished from uninstalling the app or deleting its stored data.
A practical example
A television player may remain unresponsive after returning to the home screen. A supported force-stop operation followed by reopening the app can test its running state while preserving the installed software and, ordinarily, its saved configuration on that platform.
A common misunderstanding
Do not assume every device uses the same menu or terminology. Follow the platform's supported operation, and avoid replacing a force stop with an unnecessary data wipe or reinstall.
