I updated my phone today with the same issue. Everything thing works fine all speakers and microphones, but when making a call or receiving a call the speaker is blacked out and you cannot hear or say anything.
Went to Apple, and their assessment was that there’s a mother board issue... complete ********! And coincidentally my warranty was up under a month ago. Apple sales are down. I’ve been a loyal customer for about 8 years now and I’m appalled that this is the answer I was given. First 3 calls I recurved today we’re fine. Updated and no love, yet it’s a hardware issue, they offered me $319 to replace my phone or I can buy a new one yet they are willing to give me 200 for my year old phone.
****** ******. I’m debating switching back to android. I loved Apple until they didn’t live back. Wish Steve Jobs was still around.
Angry soon to be x Apple lover
