The background tasks of the Samsung mobile phone cannot be stopped

My configuration

 <service
            android:name="com.pravera.flutter_foreground_task.service.ForegroundService"
            android:foregroundServiceType="dataSync|microphone|mediaPlayback"
            android:stopWithTask="true"
            android:exported="false" />

I hope that the task stops after the APP is killed. In most cases, it's normal, but I've tested that on the pixel4 and most Samsung models, the task still exists when the APP is killed in the background, and the APP cannot be completely killed

After the App exits, the notifications on the taskbar disappear, but the tasks cannot be stopped, resulting in the APP remaining active. My audio and video streams keep pulling and playing sounds, and the tests keep reporting bugs to me
