Iphone 7 plus No Audio Device Found

This has happened to me as well. Apple tried telling me it was a hardware issue and I would have to pay $300+ for it to be fixed. It isn’t a hardware issue because at one point I restarted my phone so many times that it finally started working again but only for half of a day. If it was a hardware issue, it wouldn’t work randomly and it wouldn’t have just happened after the update. I love Apple and always have but this is ridiculous and it needs to be fixed ASAP. I rely on my phone. I have 2 kids in school and a phone is absolutely essential. Thoroughly disappointed.

It is a hardware issue. The problem is the master clock line for the audio ic--at times the master clock can have intermittent function---the underlying defect is a loose pad under the chip. It does seem to manifest at update when the device is restarted and does a system check.

This story is becoming oddly too familiar. But nothing done. If only Apple would allow us to downgrade to the iOS on which the phone was last working.

I went into the store and they said it was a logic board issue. Is the update to iOS 12 crashing the purposefully?

-I am currently on a "no audio device found" iPhone 7 32GB-

Is it still working ?

There are no servicing options being given when the issue is brought to an Apple employee (i.e. not you). The only option given is to buy a new phone

Same thing happened to me I’m so disappointed with apple.

So if my phone is just having this issue, they won’t repair it? They will tell me to just replace it?

It's not a long term fix but my iPhone 7 that just started this is week works fine with a blue tooth ear piece.

UPDATE UPDATE:

Since I can’t edit my original post of Jan 2nd 2019 following problems with mic;

Everything started working again after resetting my phone i.e. erasing all contents etc.

Thank God!!!

When I tried to do factory reset I got an error message said factory iOS can’t be found on apple network

Hello there,

Kindly let me know on which iOS version you are running on the iPhone so that I may check the behavior there.

Thank you in Advance.

iOS 12.1.2

mine suddenly started this yesterday.

Guess that did not last long, but it it works temporarily it must be software related ?

I have the same problem with my iPhone 7 Plus and I tried all of the recommendations but none of it worked. I can only call people using my AirPods and I can’t use voice memos for homework.
