Hi,
What is wrong when the call quality from an iPhone 7 plus is so bad that you hardly can hear the person? I mean when I speak to that specific iPhone 7 plus. It shifts from good to bad, but when the owner of the iPhone 7 plus switches to speakerphone the sound is good. It has been like this since the iPhone 7 plus was new and the sound is always bad until he switches to speakerphone when I call him.
