Hi guys I've replaced USB board on my s2. I read a topic about weak signal, but my problem is my mic ain't working. The mic for in call and Google now, voice recorder and stuff. Does any one know what it could be. It's not a faulty board because it's the third one the supplier as sent me. All 3 boards have gt-i9100 rev 2.4 on them. I'm a bit stumped. Searched the net for ages but found nothing.
