Recently, several articles have been released on the problem plaguing the iPhone 7 and iPhone 7+ called Loop Disease, also known as Audio IC iPhone 7 disease.  This problem usually results in audio problems.

Essentially, the mic and speaker functions will stop working for no apparent reason.  The red button under voice memos will be grayed out.  Also, the caller can’t hear the person on the other end and vice versa.  Depending on the iOS version, maybe you’ll get a grayed out speaker.   You might get something like this:
