Hi Today when I am making and receiving calls the other person cannot hear me. I've used the Mute option in-call and also tried speakerphone but no luck. I have looked at the sound settings and none are muted. However I tried to use Recorder and I got a message on the top of the screen saying that the phone is muted but I can't find how to correct this. Can anyone help please? It's probably something silly but I really cant find it!
