SAME except AT&T said that they are tracking all phones with similar issue. My daughters did the same. Mine started when I did the most recent update. I am out of warranty, but have insurance. AT&T escalated my service to Apple. Apple denied that anyone else is having this issue and told me that I likely got water in the speaker and told me it would be $385 to fix it. AND couldn't tell me when I would get my phone back. I took my issue to Nations Cellular (a reputable service in Hot Springs... Always is honest and tells you if it can or can't be fixed... with up front prices.) He said this is a regular occurring problem with 7 plus and he has little success with fixing it. He said that it keeps appearing to be a BAD CHIP. And that usually happens on the updates.. He said that it is NOT my speaker. He recommended using my insurance to replace it if I choose to stay with APPLE. I am so frustrated. I keep my phone safe and in a case.
Everything about my phone still works except the calls and voice memos. I can't use the headphones that came with the phone (the ones you plug in) BUT I can use my car speakers and I can use my bluetooth headset. So SCREW the repair and insurance. I am so DONE with the scamming tactics of Apple and each phone company. UGH!!
