iPhone 12 Pro - Voice breaking up on calls

Did you every get a good response on this? I have the same issue- 2nd phone I’ve had with this issue now too. I can voice note clearly, record videos with sound, use MS teams with no issues but phone call I break up after 5 mins

I have had the issue since September 2020. Phone has been replaced 4 times, and I'm still working with Apple Support. Been to the Apple Store 8 times, called Apple Support 30-40 times. I was initially told that the phone has an issue with the antenna and they replaced it. They can't find anything but it has happened when I'm on the phone with them. In order to get the microphone back working, I go to Speaker and hit one number twice, not two separate numbers....I've read that upgrading to iPhone 13 fixed it for a couple, and after 7 months, I'm looking into it.

Right now, the engineers and ATT are working on trying to find a solution but both are blaming each other...so that and $8 will get you coffee at Starbucks or a gallon of gas!

If I get an answer, I'll post it.

If you go to the Apple Store, be prepared to have your phone run a diagnostic test, a hour wait, and then they will reset the phone on you and that means driving home with an empty phone.

Resetting phone doesn't work, resetting Network doesn't work, I check daily for updates, and when one is available, I download it from the computer because apparently, downloading from the phone is not the full version...or so they say. I'm in talks with Apple Senior Advisor and with Regional Director with ATT to figure this out....still think both will blame one another.

I think it's a software issue with Apple. I have had every apple phone since the 3 except the 11. I bought this phone as an upgrade to 10, and have had no issue with ATT or iPhones before getting this

Having the same issue. I tried making a voice memo, and it sounds very garbbled (likely what people are hearing on the other end), but when I record a video, the sound is fine! This leads me to believe that it's not a network issue (b/c voice memo has nothing to do with the network) or a physical mic issue (since it can pick up sound from the camera app and sometimes during calls). Not sure, what's in between the physical mic and the auditory output, but thinking it's something in the middle of those.

When I compare it to human anatomy, it's a bit like the ear is fine and the brain can receive and interpret sound, but something is happening within the 'ear canal' where the sound isn't getting to the brain, so the brain outputs garbage sound. Hope that helps someone get a solution. Going to apple this week, will follow up if I get any new info.

Follow up 3-14-2022

Contacted ATT and got a hold of their engineers and initially they found a server issue but no relevance to situation and everything is fine. Created a new Apple contact and it still is acting up.

Contrary to what you might hear, Apple doesn’t make iPhone 12 Pro Max since 13 came out. They will tell you they will replace with a new one, it’s not. Refurbished.

They wanted me to pay an additional $550 to get the 13. No way, so it looks like I’ll be getting the 4th iPhone 12🤷‍♂️

Yes same problem. Almost sounds like popping so I’m missing every other word and so is person on other end. Had this with my iPhone 11 and now with my 13 so it’s not the phone. It’s not my AirPods bc it happens without them and in car.

I wondered if there was an app causing interference maybe. Not sure how to test that.

I’m going to try switching from 5G auto to 5G all suggested above.

the only thing that helps at all for me when this happens during a call: I open keyboard and press a couple numbers and then press volume up and down a few times and the popping stops. It may return in the same call again but this makes it stop at least temporarily.

stop gap but not a solution!!

same problem. I switched to Wi-Fi calling and still have the same problem, but not as frequent. My home is located near a 5G tower, but I only get 1 bar. I have a much stronger LTE signal. The problem seem to only happen when I am using LTE. Since most of my calls are made at home, I turned off Wi-Fi to fully test the cellular signal. When I move to the back of my house, I get a 1 bar 5G signal, where cellular and internet works fine. When I move out of 5G range to LTE, I experience the call problems. In addition, internet does not work. Not sure what all this means. I thought Wi-Fi calling would resolve the problem while I am at home. All very confusing and frustrating. I will keep calling ATT.

I'm experiencing dropped calls, and when in a conversation the other person says "Are you there? Can you hear me?" and sometimes what happens is after 5 minutes of having a good connection they will say that my voice is breaking up and then they can't hear me. So frustrating. My iPhone 12 Pro Max is a most expensive fucking papeweight now!

I have the same problem.

When using my phone in our home, the person I am speaking with reports that my voice is breaking up and garbled on their end. I can hear them fine with no issue at my end.   Doesn’t happen all the time but more often than not. Current phone is iPhone 12 Pro Max, this was also happening with my iPhone 11, That’s the reason I switched from 11 to 12 promax hoping that would help. This never happened with my iPhone 6s Plus. So I don’t think it’s a 5G problem because the 11 didn’t have 5G. I think it’s a software problem or a possible microphone problem ( if the iPhone 11 and 12 Pro Max have a similar microphone)? Anyone find a fix for this yet? Thanks

I’m getting tired of getting passed from ATT to advanced ATT support to Apple. I don’t believe it’s the phone. I think it a tower issue. That’s bad news since ATT is spending all resources installing 5G. They are not going to troubleshoot a tower for a few people. In my case it may not be correctable since I live on a hill that is very close to a mountain. I was told signals may be bouncing off the mountain. The older phones may handle this better than the newer ones.

Follow up: I called Verizon and they were useless. Then I went to the apple store and explained my problem. They took my phone in the back. They cleaned it, tried a few tests (not sure what), took out the SIM card and put in another phone to see if they could recreate it. They said they didn’t see any issues. Miraculously though whatever they did solved the problem! This was months ago (Dedham, MA) I waited a few months to report back bc I wanted to be sure.

I know it. It’s ridiculous. Never in a million years did I think whatever they did would fix it. Ironically they didn’t either. But they still tried. They told me to return phone to factory settings and then manually put all my apps back. They thought it was probably something I carried over from a phone long ago that was causing it to occur on my last couple phones. But in the end whatever they did worked and I didn’t have to do that more time consuming step!

I have the same problem with my iPhone 12 and it's very very frustrating. I will be on a call and it starts breaking up during the call. I have to wait til it stops, usually about 15-30 seconds. Doesn't matter if I'm on speaker, bluetooth or iphone.

I seem to have this problem more often I’m using the speaker, don’t know if anybody else feels that way? I was also talking to a friend who experienced this with his wife on his 13 promax mine is a 12 promax. I was recently on a call and When someone told me that it was breaking up on speaker, I switched over to iPhone and they could immediately hear me. My friend with the iPhone 13 said that him and his wife had the same problem he was on speaker and switched over to regular iPhone and the problem went away, so I don’t know if it’s 100% isolated to speaker as one person above said it happened to them on In different modes, but in my case it seems to always happen in speaker of course I talk on speaker the most frequently. I don’t have an Apple Store near me in my town so I would have to take it to another repair shop but it might be worth it if they could fix it in a similar way as They did a person above.

My husband and I both have the iPhone12 and both have issues with people saying we are distorted on phone calls. Apple's help documents to try FaceTime doesn't really help when you are talking to someone on a landline. Sheesh. We have to use Wi-fi calling at home because our house is in a weird valley in our neighborhood and the call quality sucks even more. And it is not the Wifi signal. We are 200 mbps up/30 mbps down with our business internet. The only fix I've found so far is restarting my phone each and every time before I make a call. If someone calls me, I have to ask to call them back, restart my phone, and then return the call.

Apple, please fix this software issue. It is not the carriers since everyone in this thread has a different one.

Have there been any updates? I have an IPhone 12 and my phone just started doing the same thing. Ppl at the receiving end say they can’t hear me, I’m breaking up. This was not an issue 2 months ago. I also have Verizon.
