In addition to controlling volume on your iOS or Android phone, you can also set your app’s volume to soft, normal or loud. This feature will adjust voice volume and volume for trip alert sounds (e.g. trip requests, ride cancellations, etc.) without changing your phone’s volume.
Default setting: Loud
Pro tip: Keep your app volume set to loud to mirror your phone’s volume. To test your app’s volume, go online and listen for the sound that indicates you’re online.
