My iPhone 7 with iOS 11.3.1 has a problem with its microphone and headphone jack.
When I make a call, I am unable to click on the loud “Speaker” button, and also am unable to hear the person on the other side of the call. They also aren’t able to hear me. Basically my phone can make calls, but I am unable to hear the other person and the other person can’t hear me. Also my speaker DURING calls is greyed out, so there’s definitely an issue with the microphone, as if it was disabled.
Additionally, my headphones cannot be recognised by the phone when plugged in, however the phone is still able to charge. I know for a fact that the headphones are not faulty, it definitely has to be a phone issue.
I still have three months left on my warranty before I can get a new phone, so any help will be deeply appreciated!
