Hi there, @Rz84113. 👋
What is the make and model of your Android device?
Also, which Bluetooth device are you using?
Have you received any error messages? If so, what exactly does it say?
In the meantime, let's try re-pairing the Bluetooth connection between your device and the phone.
To remove the pairing, please go into the Bluetooth settings menu on your phone, find the appropriate connection, and select "Forget this device."
Once you've done so, refer to the owner's manual for your device for how to reconnect to your phone.
Let me know how it goes. 🎧
