As a precursor, I've already contacted AppleCare for my situation and have a Genius Bar appointment setup for this Saturday. Mainly, I was curious if others have heard of or experienced this themselves. Basically, at random intervals, the phone will not make any sound during a phone call. For example, I called my mother, her phone rang, she answered, and there was no sound on my end. I tried on speakerphone and the regular speaker, there was just dead air. 4 bars of signal and the call was connected, both phones showed the call connected, but she heard no sound from my microphone and I heard nothing she said at all. Yet, 5 minutes prior I had just ended my phone call with Apple on the same exact phone. It's become more consistent (daily or multiple times per day). It began a few months ago intermittently so I simply dismissed it. When I explained it to Apple they had me reset my network, run diagnostics, and nothing came back showing anything nor was the problem fixed. They assume it might be hardware related, but won't know for sure until Saturday. If anyone has experienced anything similar, feel free to discuss! For reference, I'm on Verizon in NY on an iPhone 6S Plus 128GB rose gold model. They offered to overnight a replacement, but I can't really afford the temporary hold.
