Apple hasn't acknowledged this issue yet but has been a big problem for me. Sometimes, I hear other party but they don't hear me. This always happens when I use dialpad on my car. If I use SIRI to make call, doesn't happen. Some people have commented that this seems to be a combination of proximity sensor and mic switching which could be both hardware and/or software issues.

Also,using Bluetooth, metallic distorted sound sometimes.

Anyway else having these problems? Does anyone have a fix for these problems?

Why does Apple release phones after waiting 16 months since the last one with poor quality control? They are supposed to be such a "detail-minded" company yet can't release a phone without problems. Any help would be appreciate...
