IPhone 7 microphone not working
Yesterday the microphone on my iPhone 7 abruptly stopped working. I can still hear videos from my phone and send and receive texts, but I can’t record sound on a video or voice message. I can make and receive calls, but neither end can hear each other unless I’m connected to my car’s audio or Bluetooth, and I can’t send or answer FaceTime calls. There isn’t any muffled or distorted sound in calls; it’s totally silent. It doesn’t seem to be an account problem. I tried googling what’s going on, but it doesn’t appear to be a problem with audio settings on my phone that I can change, and rebooting my phone did not fix the problem. Any ideas?
