Hello, the reason lies here: you need to switch to external Bluetooth. The built-in Bluetooth cannot filter Bluetooth notification sounds. When Bluetooth notifications play, they switch the audio channel to the media channel, causing it to lose focus.
Additionally, the built-in Bluetooth cannot automatically unpair A2DP. It cannot automatically switch audio to Bluetooth music when Bluetooth music is turned on, nor can it automatically switch back to the phone speaker when Bluetooth music is turned off.
Simply switching to an external Bluetooth device will perfectly resolve this issue. Moreover, external Bluetooth outperforms built-in Bluetooth in every aspect.
