Microphone not working on iPhone 7
When making phone calls I cannot hear the other person, and they can't hear me. My voice memos app won't let me record anything in order to test the microphone and speakers. If i take a video, there is no sound. I can get sound on previous videos though. Siri can't hear me. I took my phone to the genius bar a couple days ago, and they did a factory reset. It didn't fix the issue. He said he ran diagnostics, and only told me that I should buy a new battery. I just did apple chat, and was told I need to take it in for a hardware issues. Any other ideas? Is this going to cost me a replacement?
