I have Note10+ and I think it is stupid that I have to unplug my headphone every time I try to call somebody or send a voice message just because all my headphones have no microphones.
I had no problems with my iphone before and I think it is a simple function that samsung phones should also support.
Hey @ JSUtKiddinGG
An external device (in your case : headphones) may be preventing the microphone from working. Try using headset with inbuilt microphone and see if it resolves your issue. I suggest you to use devices compatible with your Samsung mobile to avoid trouble.
