Ive noticed something about the default Messages app on my Samsung Galaxy A71 5G.
When I have the conversation open for a given contact and they send me a new message there's no audible notification. If I switch to a different app or a different contact I do get an audible notification.
Is there a way to change this behavior? I don't see one. Just because the messages app is open to a particular contact doesn't mean that I'm looking at it.
