MI just cant believe that a spare brush that was lying in a corner of my bathroom made this happen. Even I saw that post on XDA but thought of it as a waste. How wrong was I. Lately the low sound was just unbearable. And once again i googled abt the problem. And found this post. M so excited now that both my call volume & speaker volume has increased. Like a FRESH now.. Thanxxx a lot for posting this DAVE.. LONG LIVE DAVE..
