When I am using handsfree 🎧 on my Samsung galaxy a70📱, during it if my phone rings up for a call 📞 and I attend it then I remove my handsfree from my phone automatically it doesn't change media sound to speaker instead it still shows that handsfree are plugged-in and unable to play sound 🔊through speaker🔇 moreover mic stops working and I cant listen through speaker, neither on ear nor on loudspeaker and the voice is not transmitted to the caller, phone also gets hanged.
How to solve it????
First check of any moisture or carbon issue, try changing the hands-free as it may not compatible ( some time hands-free works fine even if less compatible but results such an issue.) Hands-free has 3 connectors power, mic & speaker. Their gap between these 3 connectors make them compatible. Incompatible hands-free cases short circuit or malfunction
