Rispondi a "Microphone not working on iPhone 7. (Phone Calling and Siri)"I tried rebooting a couple of times, did not work. I then erased the phone and restored from a backup, did not work. then I stumbled onto this discussion thread which speaking with Apple support (he was suggesting to reinstall the OS from ITUNES before the backup. Before I could do that, I rebooted 2 more times and on the 2nd reboot, the phone call audio started working again.. Thanks for this thread!!!
