I had a F6 last year and went from not dev work to carbon v1 I got the zmax and used till lost it. Well, I have aquired another one. I have the latest version of carbon and every so often I get people saying either cant hear me or echo. Last time i used a script and modified the build.prop from digital to analog, but still had issues. Before i try same method I wanted to see if there was a updated fix. Thanks for the help as always.
