IPhone 7 microphone does not work? Possible solutions

Apple has distributed a document to the various authorized service centers in which we talk about possible problems with iPhone 7 and 7 Plus microphones after updating to iOS 11.3 or later versions. This problem occurs when classic calls are made or via FaceTime, with the speaker key being deactivated during these calls. This makes it virtually impossible to be heard during the call or chat FaceTime. This is an annoying problem for which Apple has not yet released any further information. If you are experiencing problems with your microphone, below you will be presented with some possible solutions to make it work like before.
