Right way to -

1. From the Home screen, tap the Apps icon.
2. Tap Settings.
3. Scroll down to 'Device (i.e., phone),' and then tap "Sounds and notifications."
4. "Ringtone" - slide down the intensity line level down all the way to silence.
5. Conclusion: Now you don't have both sound and vibration -
6. they (sound and vibration) come hand-in-hand together - you have either both or none.
