iPhone volume on a call
Since March 2022 my iPhone 12 volume on a call is so low I can barely hear the other person, though they can hear me fine. If I turn on Speakerphone, the volume is fine, so I have to use Speakerphone for all my calls, whether I am the caller or someone calls me. I have tried the obvious things but nothing works. How can I fix this?
iPhone 12, iOS 15
