Hi I have a problem, all of a sudden my phone seems to be muted. I can not even hear it dialing(it does) I can hear it ring for incoming call so not speaker. I can talk But can not hear anyone/thing. I know it is hopefully something simple. volume settings are on highest. seems to work in speakerphone mode. A few days ago I tried editing build prop, I hope it is not that because the setting I was trying to edit did not change.
