iPhone 12 Max Pro Microphone not working

Hey Christy

Forget about reinstalling and all the scripted bull. I did all of this and still did not help. I even told them I have been an Apple Distinguished Educator since 2001 and know what I am doing and talking about. Nothing they recommend works. I am certain it is a fault on some, not all, phones. I just don't know what and Apple, as they are, refuse to admit it. I understand that there are sometimes errors in mass production. I just wish they would have the balls to be honest, stand up, and admit it. At the moment, my like for the Apple, the company, is inversely proportional to my like of their products. :-)

I would suggest downloading PHONE DIAGNOSTICS from the App Store. This allows you to test everything but more importantly, it allows you to test every microphone individually across a range of frequencies and lets you know if they pass or fail on each frequency. I ran this on my phone and it consistently failed the same 2 microphones across all frequencies. I then used this as evidence there was a fault when I returned it for a new phone.

Good luck

I used the Phone Diagnostic App which showed there was a hardware fault with 2 Microphones over all frequencies. Apple replaced it and the new one works without a problem so far.

I downloaded 'Phone Diagnostics' from the App Store, a tool that allows you to check every Microphone individually across a range of frequencies. Every time I ran it, it gave an identical result that the FRONT and REAR Microphones were not responding AT ALL.

I took my phone to my provider, ran the app in front of them, and they accepted that there was a fault even though Apple STILL officially refuses to admit a fault.

I am now awaiting my replacement. When it arrives I will refuse to update to 14.3. Saying that, if Apple still refuses to admit there is a fault, there is little chance that they will fix it unless they do so and hide it in the 14.4. update.

Let's hope that TRUTH from Apple prevails.

Hi Steve I used the diagnostic and two of the microphones dont function. I agree it looks very much like a manufacturing problem to me. Off to the store for a replacement

If you look at other threads you will see that this is a common hardware failure with the microphones. . I had the same issue and returned it to Apple for a replacement which works perfectly.

Turns out it was hardware issues with my 12 pro max..

I received my new 12pro max within 3 days.!

My new device works perfectly fine..!

I’m truly happy with the Apple Service Center..!

Thanks to Apple Service Center for their fast & prompt service..!🥰

Took it in to Apple and they tested and confirmed the fault. Phone replaced with a new one.

I went to the apple store, they run some diagnostics and they replaced the phone on the spot. I upgraded to the latest software and no issues. While inconvenient I am happy with how it was handled.

Turning off noise cancellation worked for me!

Same here. Ran diagnostic app myself and then replicated by Apple at Genius Bar. Replacement phone on the spot.

Hi u have same case with me I bring my mobile to apple and they ask me to wait 1 month and they replaced with new mobile with series N they said the microphone is failed

Yes mine had the issue after the 14.3 upgrade. Given it works fine in video mode I think they have stuffed something up in that version

My issue turned out to be hardware related and they had to give me a new phone

Download a phone diagnostic app and test it. It will tell you if the microphones have failed. Then take it to an apple store and get a replacement phone. This is exactly what happened to mine

I did a total wipe and reinstall and that didn't work. Off to the "genius" bar to get it fixed
