Galaxy buds bluetooth does not connect in middle of VOIP (Android)

HI I have a question regarding trying to connect galaxy buds in middle of a voip call.
I did some logging and it seems to disconnect the Bluetooth audio SCO if the bluetooth is paired in middle of a voip call.
However for an apple air pod, it seems to work just fine.

I found the code where it seems to disconnect the SCO Audio, and I was wondering what the purpose of the code below is and if what possible errors can occur when removing bluetoothManager.stopScoAudio()?

*Update: bluetoothManager.stopScoAudio()? does not seem to disconnect bluetooth audio SCO,

Is there any way to keep the bluetooth audio SCO connected?

Any help would be greatly appreciated!

   // --- stop bluetooth if needed
        if (selectedAudioDevice == AudioDevice.BLUETOOTH
                && newAudioDevice != AudioDevice.BLUETOOTH
                && (bluetoothManager.getState() == AppRTCBluetoothManager.State.SCO_CONNECTED
                    || bluetoothManager.getState() == AppRTCBluetoothManager.State.SCO_CONNECTING)
                ) {
            bluetoothManager.stopScoAudio(); // SEEMS TO DISCONNECT SCO AUDIO HERE 
            bluetoothManager.updateDevice();
        }

Start by locating the Android code containing stopScoAudio() and updateDevice(), then compare the Galaxy Buds and AirPods pairing behavior described in the issue. Reproduce pairing during an active VOIP call and determine whether the SCO route should remain connected; the issue is done only when the intended behavior and a verified change are clear.
