About ring tones, sounds, and alerts
Your device has a Normal sound profile and six other preloaded sound profiles: Loud, Medium, Vibrate Only, Silent, Phone Calls Only, and All Alerts Off.
By default, some of the settings in the preloaded sound profiles are based on the settings in the Normal sound profile. For example, when you change the ring tone in the Normal sound profile, the ring tone in the Loud, Medium, and Phone Calls Only sound profiles is automatically updated. If you do not want specific settings for a preloaded sound profile to update automatically when you change the corresponding setting in the Normal profile, you can manually change the settings in that preloaded sound profile.
You can create custom sound profiles. When you assign a custom ring tone to a contact, the ring tone is always active and does not change when you switch sound profiles unless you switch to the All Alerts Off sound profile. Call and message notifications for your contacts might be audible even if you switch your sound profile to Silent or Vibrate Only.
You can change, rename, and delete most preloaded sound profiles. You cannot delete the Vibrate Only sound profile and you cannot change, rename or delete the All Alerts Off sound profiles. You can change the Normal sound profile, but you cannot rename or delete it because some of the settings in the other preloaded sound profiles are based on the settings in the Normal sound profile.
