Can’t hear or be heard on iPhone 7 Plus
I had the above problem, but got a new phone. I now need to use the old phone for my daughter . . I put a sim in my old iPhone 7 Plus and updated to latest IOS, and made calls and revived calls . All worked perfectly. We then did total reset and added her Mac profile , and now same old problem , and speaker icon greyed out. Can’t be hardware because it worked perfectly . Any suggestions ?
