Anyway, a friend of mine gave me his Flex the other day. He was upset because he couldn't get the sound/audio to work and no one could hear him on his end, showing his mic wasn't working (first time this has happened). After tinkering around for a bit (cleaning over and over), trying everything I could, even downgrading it from 4.4.2 to 4.2.2 to see if it was a software problem. Still nothing. Yet, when a headset or just normal headphones are plugged in everything works fine.
So, after all of that we took it in and they said it wasn't a hardware problem, but they couldn't find a solution and they couldn't replace the handset with his warranty already expired. So, I was hoping there was someone here who could help me. I was thinking maybe if there was a software problem I didn't catch if installing a custom rom on it would help. I was hoping to hopefully get some insight before going to that.
Also, sorry if this is in the wrong section, still new here.
