iPhone 7 Mic Problem iOS 14

Although the authorized service offered me a paid exchange, I did not accept it. As a result of my contact with an iPhone repairer, I learned that iPhone 7 phones have chronic iPhone 7 Audio IC problems. I had it fix at an affordable price. However, this is Apple’s engineering fault and Apple does not accept it.

Try resetting by power+volume down button until the apple logo appears. It worked for me:) hope it helps!

I took it to a High St mobile repair shop. £100 for a new audio drive. Cheaper than a new phone.

Yep, absolute nightmare ( 7 plus ).

Reminds me of Ubuntu - while that one was at least free :(

The only workaround is:

1) totally turn off bluetooth in the settings ( not from the bottom panel ! )

2) reboot

But it reoccurs after you turn on bluetooth.

I think its something related with new access permissions management.

Unbelievable I had exact same problem after the upgrade. Did everything as shared in many posts but no good. I can connect to Bluetooth device but cant connect anything using audio. I went apple store as well and as expected they are saying hardware showing dead/no presence and offer a replacement with $370+taxes for similar iPhone 7 as i am out of warranty... Way to go Apple and with losing customer loyalties....

That's insanely great, and here is the update:

Love to hear it -- this kind of Apple's behavior (denying, ignoring, covering) is certainly not acceptable.

if it’s not software problem/repair then this is what has to get fixed on iPhone 7/7 plus as it an issue with these models (even with iOS updates before which Apple acknowledged first time in 2018) - there is a video of repair

No, everyone doesn't say that. If you do a search you will find many posts where people's Audio IC came loose and failed NOT during any update. As I said earlier a major update can reveal the flaw as it sends signals to different components of the iPhone and can end up with a failure. And there are some instances where doing a restore MAY resolve this for a while.

But my iPhone 7 Plus, which I passed down to a woman with 5 little boys, DID NOT fail during an update. She started having intermittent problems with it and then finally she could only use it with BT headphones/speakers. The first to go for her was the microphone on the bottom of the iPhone, second was wired headphones and finally the speakerphone failed.

I forgot one more option: I traded that phone in on an iPhone SE 2020 for someone else who broke their iPhone 6s. They did not check to see if the speaker or mics worked.

You can search the internet for virtually anything and find some nitwit fact. Notice you said focused on not that it happened. But no programmer can right software that will cause a solder ball to break connection with the logic board. It is a matter of physics and science.

Some people do have issues with the microphone or speakers or a speaker not working that may be software. But it can normally be resolved. But when mine stopped it was not after doing an update and all mics and speakers failed. As I said earlier in this thread you can slap the phone into the palm of your hand or press hard on the middle up on the right hand of the screen and sometimes make it work temporarily. That will be hardware.

I traded mine in.

Hey guys had the same problem and I found a solution! Go to settings->general->reset->reset network settings. I know it's weird that this help but you're welcome! Deffinetly IOS 14 fault.

I can’t believe, but I try a trick.

I found out in ifixit.

If you pushes the screen at the moment of the restart the phone , the mic back to work.

I tried, it’s works.

Old firmware isn't going to work. The update killed the chip inside the phone. Find a repair shop that fixes phones it should be cheaper.

Try hard reset. Need to hard reset couple of times. I was with same issue (iPhone 7+ with no mic to use, literally can’t call voice n hear calls)

i just got it sorted today after about 1 week -2

Not too sure what removed post you’re talking about.

I don’t work for Apple, I had an iPhone 7 that did the same thing with the iOS 12 update, I was just as confused and determined to fixed the problem as everyone here so I tried to research the answer, combing through the internet and watching YouTube videos of people re-soldering the audio ic back in to place and after that the problem is fixed.

For everyone sake, I hope I’m wrong. I hope it’s a simple software solution, I tried waiting for the updates as well in iOS 12 and that didn’t fix it.

I’m not a troll, I’m trying to help this thread understand the position they’re in, the same position I was in a year ago.
