The ability to customize notifications for contacts is easily my favorite new feature on 10.3.1. I don’t even have to pick up my phone to see who I’ve received a message from – the LED, vibration, ringtone and other sound settings can be customized for each contact.
To customize notifications for contacts:
  1. Go to settings
  2. Notifications
  3. Contact notifications
  4. Tap the + icon
  5. Select a contact
  6. Select an app behavior for the contact
  7. Customize sound, ringtone, vibrate and LED for that contact
  8. Go back to save your settings

Customizing app notifications:

  1. Go to settings
  2. Notifications
  3. Select a notification profile
  4. Click “Customize App Notifications”
  5. Select each app and toggle its settings
Individual contact settings override the default profile setting. For example, if the active profile is “silent” but BBMs from a certain contact have been set to vibrate, the latter will override the former.
