Why does navigation audio play through my phone speaker instead of my headphones on Android?
Last updated November 5, 2026
Navigation audio in the Apollo Scooters app interrupts music but plays through the phone speaker instead of connected Bluetooth headphones while riding. This occurs on Android devices like the Samsung Galaxy S25 Ultra, even when Media Output is set correctly. It's typically a phone audio routing issue, not an app problem.
Symptoms
Music pauses correctly for navigation prompts.
Navigation voice comes from the phone speaker, not Bluetooth headphones or earbuds.
Affects navigation during rides with headphones connected.
Step 1: Verify Media Output
Swipe down from the top of the screen to open Quick Settings.
Tap Media output.
Select your connected Bluetooth headphones from the list.
Note: if it is already set to your headphones, go to Step 2.
Step 2: Enable Separate App Sound
Go to Settings, then Sounds and vibration.
Tap Separate app sound and turn it on.
Select the Apollo Scooters app (or Google Maps if integrated).
Choose your Bluetooth headphones as the audio device.
This routes navigation audio specifically to your headphones while other apps, such as music, can use different outputs.
Additional checks
Make sure your Bluetooth headphones are fully paired and connected.
Test with another navigation app (for example Google Maps on its own) to isolate the issue.
Restart the Apollo app and your phone after changes.
Update the Apollo Scooters app through the Google Play Store.
Prevention tips
Always check Media Output before rides with multiple audio sources.
Use Separate App Sound for consistent app-specific routing.
Mount your phone securely with Quad Lock so you can see the app dashboard during navigation.
