If the Samsung Galaxy Note 9 has difficulty establishing a stable connection to other Bluetooth devices, such as the car hands-free from VW, Mercedes, BMW, Audi, Opel, etc., then a faulty data cache in the Bluetooth system applications from Android can often be responsible.
In this case it often helps to reset the Bluetooth settings of the system applications.
This is done in the Bluetooth apps of the Android system that are responsible for this, as this is where the control takes place. Our step-by-step instructions will show you exactly how to do this:
