About ring tones, sounds, and alerts
Your smartphone has a Normal profile and five other preloaded profiles: Loud, Medium, Vibrate Only, Silent, and Phone Calls Only. You can change the tones in any preloaded profile to an audio file that is stored in your smartphone storage space or on a media card, or you can create additional profiles. The All Alerts Off profile can't be changed.
By default, some of the settings in the preloaded profiles are based on the settings in the Normal profile. For example, when you change the ring tone in the Normal profile, the ring tone in the Loud profile, Medium profile, and Phone Calls Only profile is automatically updated. If you don't want specific settings for a preloaded profile to update automatically when you change the corresponding setting in the Normal profile, you can manually change the settings in that preloaded profile.
You can create contact alerts, which alert you when particular contacts call you or send you a message. Contact alerts are always turned on, and don't turn off unless you select the All Alerts Off profile. For example, even if you select the Silent profile or Vibrate Only profile, audible contact alerts remain audible until you select the All Alerts Off profile.
