Anyone have regular static in earpiece or problems with microphone? From what I understand, a hand over the antenna (top or bottom) can contribute to static, but even when making sure hand is placed in center, free from either end, I still have static unless I switch to speakerphone... Also, my microphone only transmits about 50% of the time, meaning, the person on other end hears nothing, unless I switch to speakerphone. However, coincidence or not, it appears the mic is more likely to work if I toggle to speaker and back to regular. I first recognized the problem while running google navigation in the background when I answered a call, so I thought at first it was connected to that but it hasn't gone away since... any help would be greatly appreciated...I really don't want to have to get a replacement if I don't have to. Thanks!
