So lately i've been hearing people complain that they can't hear me and that the 'line is really bad' even though i can hear them clearly. So i decided to investigate the mic since that would be the probable cause. To do this i compared the phone with my old Treo 680. I gave the 680 to my brother to act as the call recipient and when i called he said my voice was patchy and low and barely audible. I had to literally move the phone away from my ear and point the mic directly to my mouth before things got better I then switched the phones and gave my brother the iPhone and i used the Treo to call and he said the call quality was miles better and he could hear me loud and clear I admit i hadnt noticed this earlier because i'm a heavy txter and rarely make calls. So is this a common issue or is my phone just defective? and is the 3G model's mic better?
