Iphone 7 speaker no longer working. Speaker is graded out when making calls. I can't hear and people can't hear me. The microphone button doesn't work on text
My speaker on my iPhone 7 doesn't work anymore. When I make or receive a call I can't hear anyone. The speaker icon is grayed out when I make or receive a call. The microphone button to talk a text no longer works. My phone hasn't gotten wet or been damaged in anyway.
Please advise.
