My sons iphone 7 had the same issue with greyed out speaker. Called the customer support did the whole reset thing and made an appointment for the apple store. Went to store and they said it was "user error" that he must have dropped it. Bullcrap! I showed them the article printed May 2018 that showed it was a known issue and they knew about it and they said, thats as of June 2018 they investigated the accusations and ruled out the update caused the issue. So apparently only Iphone 7 users are klutz's who drop their phonez. They wanted $319 plus tax to replace. I turned to my son with the apple store manager there and said "Welcome to Samsung".
