Simply, I used to hit the microphone on the dialer, say a store where I want to go, it would load the store info and I could click a dial phone button and call them. Now NOTHING happens, like buttion is dead. A few days ago while it was breaking, it started playing a video (just heard some audio) when hitting that button, but now nothing. I also turned phone off but it is still not working. The microphone works fine. I hear the noise when you click the button. The microphone icon button next the green handset button is what is broken.
