iPhone 4S mic not always working
I have been having intermittent issues with my iPhone 4S where the mic will stop working for periods of time. I believe it is software related because in the past two occassions, rebooting the phone will fix the issue.
When the mic isn't working, the phone, Siri, and voice notes will all register no sound from the microphone.
Has anyone else had this problem? Is this something that will be fixed in an upcoming update, or do I need to take the hardware in to be replaced?
