microphone does not work on iphone 12 pro

So I was reading around, people with iPhone 7, 8, and 11 pros are having the same microphone issue after updating to iOS 14... it seems this update is blocking something in terms of the microphone

There is no left speaker. The left grille is the microphone. The right grille is one of the speakers. The other speaker doubles as the earpiece when you hold the phone to your face. This arrangement has been true for all iPhones since the iPhone 4.

You can join the iOS open beta, but betas tend to be buggy, so you take the risk of having other issues, and you can’t get support for beta issues in this public forum. See ➡️ https://beta.apple.com/sp/betaprogram/faq

Interesting insight! Since I paired a new Apple Watch last week, I decided to review and compare the videos recorded before and after pairing the device. Lo and behold, the mic issues started the same day I paired the watch (in fact, I noticed the issues precisely because of the static sound on any videos recorded with the iPhone camera app, while videos on other apps -such as Insta stories- work fine). Maybe I’ll give re-pairing the watch a go! Will keep you all posted.

I have had this problem since my first day of getting the iphone 12 pro. When I'm on facetime or speaker phone the person on the other side will see and hear me talking then all of a sudden it just goes silent on their side and they can see me talking but don't hear anything. I talked to apple support and did everything with resetting facetime and the phone and then resetting the entire phone completely. I was told this was a hardware problem so I should reach out to my cell provider and get a new phone. I did that and got my new phone 2 days ago and IT HAS THE SAME PROBLEM! This is very frustrating, and I did not expect my new iphone 12 pro to have this problem. When will this be fixed? Is this truly a software issue or will this over $1k phone always have this issue?!

Same problem here with my iPhone 12 Mini... on regular phone calls, input audio cuts out and no one can hear me, or they say the sound is degraded (robotic/choppy). Running 14.2.1, case/no-case, multiple resets, noise cancel on/off, speaker-phone on/off... none of the proposed fixes have worked. Hardware-wise, the mic works as expected for voice memo and video.

I will add that it also happens while using my Bose bluetooth headset. Possibly unrelated, I'm not hearing the dialing sound while the phone is connecting, and the first words of the person who answers are truncated. The conditions (location/network) are no different than what was working fine for my iPhone X.

It needs to be stressed to Apple how critical this issue is. I use this phone for work and it's unacceptable that I'm unable to facilitate meetings. The audio failed again today while trying to make a doctor's appointment... I can't imagine where I'd be if it had been a 911 call.

I have the same issue in Denmark, But not When I am using my Bluetooth headsets.. So for me it seems to be a microphone/hardware issue.. Which is... So not cool...

And with the price of this phone around a 1000€ I would expect it to be working flawlessly and crisp...

Yeah no crap! My fiancé had to go back twice and we live an hour away!!! Like seriously wasting everyone’s time when they know what the problem is, but they don’t care about their people to fix it. Own up to your problems. We finally were able to switch out the phone to a new one, after telling the first guy that we had to do that. “Just restore your iPhone and it’ll work”. Just for us to go home and not have it work, after us telling the guy it wouldn’t...

The mic on the back is not the main microphone, which is at the bottom of the phone on the left, where all iPhone microphones have been for 13 1/2 years. The microphone on the back is for noise cancellation. The way it works is if both microphones “hear” the same sound at the same level it is considered noise, and the phone briefly mutes the mic. The Apple engineers know what they are doing, you just don’t understand the design.

I have the same issue on my newly bought iphone 12 pro. My case is specifically designed for Iphone 12/12 pro so it is not covering any microphone holes at the bottom or at the back so obviously it is not the case issue. My iphone is updated to ios 14.2.1 and still having this problem.

Haven’t tried noise cancellation switch off but i felt holding the phone in my hand instead made the problem little better (not completely fine) than keeping it on the table while on speaker. Had Iphone X before with no issues whatsoever.

Same issue with my iPhone 12 mini running iOS 14.3, original Apple leather case with MagSafe. Strangest thing is that FaceTime audio works fine, but as soon as you switch to video the mic stops working. Same behaviour when using WhatsApp.

I am returning my iPhone 12 Pro. I tried noise cancellation, update, factory reset, recording on voice memo, camera. Seems like a bad software problem with a whole batch of phones. How could apple do this? They unleashed a product that wasn't tested/ ready and treated its customers like test subjects. Solution is to return this device and wait for the next iPhone model where they have possibly fixed this bug. Perhaps when the pandemic is over, they will test the device properly before launching it. Or a simple solution is to shun apple completely as it appears to me that being hideous is their new mantra.

I can't believe I got this phone - in times when majority of the work is done virtually. And I work in a hospital. What apple did with this phone is nothing short of criminal.

If it is still within the Apple warranty period I would RETURN IT ASAP. Let's all make Apple painfully aware of this issue until it is both acknowledged and resolved. They just had recorded profits so I think they can afford some R&D to fix their flagship product!!

I have returned 3 iPhone 12s without any change in this issue.

I hope the recent 14.4 updates will have a positive effect but the patch notes did not say anything about a microphone fix for our collective issue. After 15+ years with Apple, this is my first major complaint.

Update:

I just returned all 3 of our iPhones without any change in this issue. (12/12pro/12proMax)

I hope the recent 14.4 update will have a positive affect but the patch notes did not say anything about a microphone fix for this issue. 15+ years with Apple this is my first major complaint.

My advice is everyone should return their phones to Apple as many times as possible while under warranty. Apple needs to step up and both acknowledge this issue and FIX it.

Bhavesh210, You suggest that a new user posting to this Tech Thread should read the full thread? To find the resolve? lol, that would be a ghost hunt at this point. 

The closest thing to a “resolves” posted here is that a few people reported getting a replacement phone and the issue went away. However, many people (myself included) did solve the issue with a replacement. Same issue different phone. 

Right now we are the lab rats for Apple as we all test different settings, talk about our experience, and monitor phones for issues. 

I will keep trying some of the posted suggestions, going for a second set of replacement phones soon, and hoping for a software fix. Good luck to us all...
