If you face issues detecting small movements, this might be a direct consequence of the Debounce value. The debounce value is a number (in meters) used to determine if the location publish should be suppressed to avoid drifting in a small area due to inaccuracies in the location provider. The default value is 50 meters if this is not specified, indicating that if the location published is less than 50 meters from the previous location, then it will be ignored. Set to 0 to disable debouncing completely, or set it to a distance of your preference..
