When your Bluetooth device is connected to your phone, the Olelo app will automatically detect it.   During a call, the Bluetooth icon should appear in the call menu when a Bluetooth device is connected to your phone. Just tap the icon to toggle between speakerphone, handset, or Bluetooth mode.   Tip: If you don’t see the Bluetooth icon, check your phone settings to make sure Bluetooth is enabled and connected to your Bluetooth device.
