Choppy, Robotic, Muffled Calls on iPhone4
Hi, I do have an issue with my iPhone 4 GSM. I get to call someone, and I get to hear them a-okay. However, they seem not to hear me correctly.
I tried searching over the internet and found that it may be an issue somewhere with the noise cancellation microphone, that it maybe dusty or dirty. I tried putting in pressure of air into the headphone jack and the very tiny noise cancellation microphone and it seem to have worked. however, there are still times that the robotic sound would occur.
How could I still go about this issue despite the efforts of cleaning it out?
Is this a good question?
