In ring mode, iPhone plays all sounds. In silent mode, iPhone doesn’t ring or play alerts and other
sound eects.
Important: Clock alarms, audio apps such as Music, and many games still play sounds through
the built-in speaker when iPhone is in silent mode. In some areas, the sound eects for Camera
and Voice Memos are played even if the Ring/Silent switch is set to silent.
For information about changing sound and vibrate settings, see Sounds on page 139.
You can also use the Do Not Disturb setting to silence calls, alerts, and notications.
Set iPhone to Do Not Disturb ( ): Go to Settings and turn on Do Not Disturb. Do Not Disturb
keeps calls, alerts, and notications from making any sounds or lighting up the screen when the
screen is locked. Alarms still sound, however, and if the screen is unlocked, Do Not Disturb has
no eect.
To schedule quiet hours, allow certain people to call, or enable repeated calls to ring through, go
to Settings > Notications > Do Not Disturb. See Do Not Disturb and Notications on page 132 .
