iPhone 12 Microphone Issue
My husband and I both upgraded to iphone12s in November 2020. We both experience this same issue, when on a voice call the conversation starts fine. Then suddenly the person on other other end can no longer hear us. We can still hear them. It happens with both our new iPhone 12s.
We have tested all three microphones and they work. Calls start off fine, it occurs randomly but super frustrating. We never had issues with our older models. The iPhone 8 appears to be more stable than the iPhone 12.
iPhone 12, iOS 14
