iPhone 7 plus does not ring only vibrate
I purchased an iPhone 7 Plus a month ago. It worked totally fine, and then all of a sudden, the phone stopped ringing. So unless I'm holding it or I hear the vibrate's, I miss all my calls.
Went to apple. They swapped the phone over. It's been 2 weeks and it has started happening again.
Any solutions? Apple doesn't seem to know how to fix the problem...
