Ok, for those that have had others tell them their phone has a bad echo on their end, try removing your case. When I first got my SR and ran it naked, the audio on both ends was loud and clear. Then I put a SGP Neo Hybrid on it and everyone told me I had a bad echo on their end (even though my side was still loud and clear). I removed the case and no more echo! Others with both the Neo Hybrid and Otterbox Commuter have had similar results.
