Change iPhone sounds and vibrations
In Settings 
, change the sounds iPhone plays when you get a call, text, voicemail, email, reminder, or other type of notification.
On supported models, you feel a tap—called haptic feedback—after you perform some actions, such as when you touch and hold the Camera icon on the Home screen.
Set sound and vibration options
Go to Settings
> Sounds & Haptics (supported models) or Sounds (other models).To set the volume for all sounds, drag the slider below Ringers and Alerts.
To set the tones and vibration patterns for sounds, tap a sound type, such as ringtone or text tone.
Do any of the following:
Choose a tone (scroll to see them all).
Ringtones play for incoming calls, clock alarms, and the clock timer; text tones are used for text messages, new voicemail, and other alerts.
Tap Vibration, then choose a vibration pattern, or tap Create New Vibration to create your own.
Turn haptic feedback off or on
On supported models, go to Settings
> Sounds & Haptics.Turn System Haptics off or on.
Tip: If you’re not hearing or seeing incoming calls and alerts when you expect them, open Control Center, then see if Do Not Disturb is on. If 
is highlighted, tap it to turn off Do Not Disturb. (When Do Not Disturb is on, also appears in the status bar.)
