microphone icon on home screen
The home screen of my iPhone 12 Mini shows a blue microphone icon in the upper left corner. I did some fiddling around with my mic settings when "Hey, Siri" wasn't working upon activation. Another issue (possibly related) is that when texting, talk-to-text is automatic. So, even if someone else in the room says something while I'm texting, their words are entered into the chat window. Help, please! Thanks.
