Presumably for safety purposes, when my Galaxy S21 is paired with my car, it will only send me a sound alert from an app via Bluetooth through my car's audio system and not from my phone. And turning off Bluetooth on my phone doesn't help either. The phone apparently still knows it's paired to my car and will not make a sound alert. So if I want to hear a sound notification from an app, I have to set the source of my car audio to "Bluetooth" and then I do hear a sound alert from apps through my car's audio system. Of course if I do that, I can't listen to the radio, etc. so it's not a good solution. I've visited various Android forums discussing this problem and could not find a useful solutions like an option to play sound notifications both through Bluetooth and my phone. Ironically, my old Samsung S4 would make a sound for every app alert even thought it was paired to my car while I was driving. Suggestions will be welcomed please.
