microphone does not work on iphone 12 pro

I recently bought the iphone 12 pro. When I use facetime or facebook messenger video chat, the audio becomes choppy for the other end. Is it a hardware problem or software?

iPhone 12 Pro, iOS 14

Bought a new 12 pro max for my wife about a week ago. Didn't think about testing it out of the box first before transferring her data over from her old 7 plus. So don't know what IOS version the 12 came with and if the mic was working then or not. We had to update to latest version (14.4) in order to transfer wife's data over and so we did. Transfer went well and everything appeared to be working fine. A few days later wife tried to make a Facebook messenger call with me and I couldn't hear her at all. We then tested FaceTime and tried making phone calls...other couldn't hear a thing...nada. Tested the Voice Memo app and when playing back a recording all we could hear was loud static. To Google we went looking for a solution or to see if others were experiencing similar microphone issues. Low and behold, we found two threads, this one and another at: https://discussions.apple.com/thread/252186963?page=1

Did all the troubleshooting and even did a factory reset as a new user and issue still there. Download ‎Phone Diagnostics on the App Store (apple.com) as suggested from someone on the other thread, ran it, and the bottom mic FAILED!!! Using a Bluetooth headset works but such an inconvenience. Took the 12 to Apple store and returned that sucker before the 14 days was up. So disappointed to have paid over $1000+ for a phone and the mic doesn't even work! I especially feel sad for my wife as she was really looking forward to the new 12 pro max, and we were going to use it to shoot photos at our upcoming baby shower :( Holding out on getting another 12 until there's an official fix or Apple acknowledges it. Might even have to wait for the 13 or switch over to Android.

I just purchased the IPhone 12 Pro and I have the exact same issue when using Messenger to speak. The person I am speaking with says I sound muffled or the audio is choppy. If I use headphones then they are able to hear me just fine but this is not a solution to the problem. I am very saddened that such a basic feature was not tested properly. Thank you for posting this so I know that it is not just my phone and that this is a wide spread issue.

Thanks you for your list of tried remedies. I just got my iPhone 12 Pro 4 days ago. I’m having the same microphone issue. Hey Siri doesn’t work...I tried to re-record my commands and the phone won’t register that I’m talking at all. Calls made with Bluetooth devices are fine. Any attempt at voice text when not connected thru a Bluetooth device doesn’t work. It’s a flat line as if I’m not talking at all. Yesterday everything worked fine. There was a new iOS update 2-3 days ago but my microphone worked since then. Just now I answered a call. Tried to put it on speaker but they couldn’t hear me. Took off speaker and it was fine until it wasn’t. Person on the call told me there was static on there end during the time they couldn’t hear me. This is very frustrating after spending so much on brand new equipment.

Got a new iPhone 12 Pro around Christmas and it worked fine for 3 weeks until I tried to use speakerphone on a normal call and the other end couldn’t hear me. Voice memos and Hey Siri dictation also failed to work.


I have an appointment tomorrow with an Apple Service provider (since Apple stores are closed in California) that I had to schedule a week in advance. Out of curiosity, I tried my speakerphone, voice memos, and Hey Siri and THEY’RE ALL WORKING AGAIN OUT OF THE BLUE.


and unfortunately I don’t know how or why. Kinda feel silly about going to a service provider now if I don’t have any problems to show.
