Apple says mic problem affecting some iPhone 7 models with iOS 11.3 or later
Apple is aware of a problem in which the microphone will stop working on iPhone 7 and 7 Plus models running iOS 11.3 or later, AppleInsider can confirm.

Affected phones may prevent owners from being heard in FaceTime or conventional phone calls after upgrading to iOS 11.3, or using speakerphone functions. It's an "extremely rare problem, with a need for repair being rarer still," a source told AppleInsider.
According to an internal document sent to authorized service providers, seen by MacRumors, repair technicians should be asking customers to disconnect any audio accessories, then running diagnostics if the problem persists. "Device could not detect dock" or "accessory not supported" messages will pop up for affected iPhones, at which point repairs can be made.
Crucially, in the case of this specific issue, Apple is reportedly allowing providers to request coverage exceptions for customers who are otherwise out of warranty.
The association with iOS suggests a software glitch, but possibly one breaking hardware or triggering compatibility conflicts, given that Apple is suggesting repairs.
People who think their iPhone is suffering from the problem should book a Genius Bar appointment at an Apple store, talk to an authorized servicer, or contact Apple's online support.

I just want to be able to use the Phone to converse. So I will get the next Apple Wireless EarPlugs and the Next Watch and the Next Computer with a wide screen meets my needs and it better not have this stupid keyboard that they have introduced in the past few years. I touch type and it is terrible for me. The key travel is off. The distance between the keys is off. It will not be a 12" screen MacBook. I often use the other ones I have.
Need I had the iPads are great. But I want to run some A series Apps on my Mac. The mouse pointer would be fine. Either do it in software with they can already do in the lab or put an A Series in with an AMD or Intel chip or Run iOS and MacOS on a new A series chip. Before I die will be best.
I Love and am Heavy Apple.
