not able to hear anything during calls/make calls after iPhone 7 upgraded to 15.7. Apple support failed to resolve the issue.
I too am facing the same proble with my iPhone 7 after the software upgradation to 15.7, not able to place calls and if in case i am able to, then not able to hear anything, neither can the person on the other side hear me. Apple support failed to provide any resolution. Tried each and every possible thing to make it work but its a software glitch!!!
iPhone 7, iOS 15
