What are my Notification Options on my Samsung Galaxy S III?
You can adjust your notification settings on your mobile device by turning sound notifications on or off and by changing the sound you hear when a notification arrives.
To adjust the sound notifications on your device, open the Notification Panel by swiping your finger from the top of the screen to the bottom, and touch Settings > Sound. You can adjust the volume of the notifications by touching Volume and adjusting the volume level for Notifications. You can change the sound played when you receive a new notification by touching Default notifications and selecting a new ringtone from the list. Select Silent from the list to turn notification sounds off even when your device is in normal mode.
