How do I stop my phone switching the microphone to Bluetooth in a parked car?
Our answer
Choose the handset microphone explicitly in the call app and disable the car hands-free profile when you do not want it.
Why this approach makes sense
Device software, permissions and connected services change how a feature behaves; use settings for the actual model rather than a generic workaround.
Before you try it
Verify the relevant device and account permissions, and make changes one at a time.
