Cannot find nearby BLE beacons (iBeacon) when streaming Bluetooth audio in car

We are expecting to receive nearby Bluetooth beacon advertising while connected to Bluetooth in car,
but as soon as we start streaming music, phone cannot discover beacons until music stops.

The connectivity issue occurs on Samsung S8、S9 and S10, but NOT on Google Pixel 4.
Also, we noticed that issue does NOT occurs while connected via standard Bluetooth audio speaker.’

The HCI Bluetooth snoop log for comparison between Samsung S8 and Pixel 4

Thank you.
