Calls play through car audio with Android Auto instead of Bluetooth headset connected to Galaxy phone
When using Android Auto, calls from your Samsung Galaxy phone may play through the car's audio system instead of your Bluetooth headset. This behavior is due to Android Auto's audio routing, which prioritizes the car's Bluetooth system when both devices are connected. This article explains how Android Auto manages call sound routing and provides tips to ensure your calls play through your preferred device.

Bluetooth audio routing
When using Android Auto with both a Bluetooth headset and a car's Bluetooth audio system connected, the audio routing for media and calls is as follows:
- Media sound: Due to Android Auto's media priority policy, media (such as music) is always output through the car's audio system. Call passthrough to the headset is not allowed in this scenario.
- Call sound: The call sound is routed to the last connected Bluetooth audio device. If you start the car while on a call using a Bluetooth headset, the car's Bluetooth audio system becomes the last connected device, and the call sound will switch to the car's speakers.

Tips for managing audio
- If you receive a call while wearing a Bluetooth headset while driving:
Answering via the car's navigation screen, steering wheel remote control, or your device's call button routes the call sound to the car.
Answering by touching the Bluetooth headset routes the call sound to the headset. - To avoid confusion, ensure you answer calls using your preferred device (headset or car system) based on your needs.
- If you frequently switch between devices, consider disconnecting one device before starting the car to maintain consistent audio routing.
Understanding how Android Auto handles Bluetooth audio ensures a smoother experience when using Android Auto with multiple Bluetooth devices. For further assistance, refer to your device's user manual or contact Samsung support.
