iPhone 12 can’t speak on phone calls

I did factory reset thru iTunes, not too big a deal as long as you have enough storage space on computer for IOS download. It didn't necessarily work for me, but I restored settings using a back-up.

If you don't use your back-up - you will have to rebuild all your contacts and settings. But maybe starting from scrath isn;t a bad thing. I was told by a Verizon in-store rep that Apple has notified them they are aware of the issue.

Advise on how to set to 3G.

This has happened to me as well. I have worked with Apple support multiple times. It takes about a week to start, but then it will continue to happen at greater frequencies. I eventually get to the point that I have to have a Bluetooth device to answer calls with any reliability, but eventually this too will stop working fully. I have made sure that my waterproof case is not the cause, and worked with Verizon to ensure that it is not a signal issue. I am on my third phone. If I have to replace it again I will ask for a new model.

Hi, Guys! I have been having the same issues with my iphone12 pro. It is less than a month old and whenever I call someone, they cannot hear me but I can hear them clearly. I Checked the mics they’re all working properly I even ran a diagnostic test and it all is pretty normal. Have had it troubleshooted on my end, I also tried escalating it in the apple support team but all were not helpful.

However, my husband and I figured out the answer to this COMMON PROBLEM.

I didn’t know that when calling someone, your DATA should be off. Probably, it’s because it’s interrupting the signal? But it worked for me. Usually, I use my data and it’s always ON. And I didn’t realize that until my husband tried to call me while he’s next to me. Now, I am happy my phone is totally working and the caller hears me now whenever he calls. Give me a feedback if it works for you, too.

I am on my 4th iPhone Pro Max, part of this is due to my circumstances, but every phone within a few weeks of getting it developed issues with people no longer being able to hear me during the call. It will start on just the phone, and I can use my Bluetooth devices to get around it for a while. That will eventually stop working as well. Speaker function has always been hit and miss. I have turned off the noise canceling function, tried the cellular data fix, and nearly every offered idea on this discussion.

Last week I talked with Apple Support again, and this time I was able to have family take my phone into an Apple Store, who were extremely polite and professional in dealing with them. This time I have turned off my VPN. I started having issues with Bluetooth connection dropping while the phone stays connected about 3weeks ago (not the mic dropping), so I have to manually flip back to the bluetooth device. This is still occurring. I have had one call drop sound since we had the phone checked at Apple, and a few calls where I am told I am hard to hear because I am breaking up. So, try turning off the VPN and see if you get an improvement.

Good Luck everyone

Saw article on Apple’s fix on the connectivity issue. Google it! It will suggest you go to apple authorized tech and get it fixed for free. Apple is quietly doing this. As long as it fixes my iPhone 12pro for good, I’ll be happy!!!

If anything it would be the microphone in your case jimibailey

You can test your microphones here:

If the microphones on your iPhone aren't working - Apple Support

make sure your data is off when you’re answering or making phone calls. This happened to me and I was having the same problem. The next time around I tried switching my data off it worked flawlessly.

Hi. Make sure your data is off when you answer or make a phone call. It worked like magic for me :)

my wife was having this issue with her 12 max pro almost immediately out of the box. took to verizon and they replaced the SIM card a the solution. it worked for a few weeks but the issue is back. I started having the issue with my 12 pro today. i had previously spoken to verizon support via on-line chat - and they had me only resetting the network settings and this works temporarily. hoping for a permanent solution.

our update as the saga continues....12 max pro - 3 trips to dealer, 3 on-line service chats, new SIM card, reset network settings, turn off 5G, reset to factory setting - none of it worked. Rec'd replacement phone - 1st call, same issue. spouses 12 pro is having same issue, and actually seems to be getting worse by the day. UGH this is frustrating.

This is happening to me as well. Sometimes the microphone doesn't work from the beginning of the call and sometimes it stops working in the middle of the call. I can always hear the person on the other end. Speaker phone mode always works.

This is happening to me as well! Its so frustrating I have Verizon my service is always good. I know it’s not my microphone because it works on face time and when I use voice on my keyboard board ...just disappointed this phone cost way to much to not even be able to do the bare minimum have a phone call!!! Will be seeing how it can be fixed or return it...smh

It definitly must be a software bug as it happens on all 3 iphone 12 pro maxs in my household.

weirdly if I initiate the call my wife can’t hear me and neither can I hear her but when we hang up and she initiates the call everything is fixed.

to fix the problematic device the only solition is a reset and everything works for a couple of days.

at times when the problem starts happening the mic and speakers all work on other apps except phonecalls.

Now it started to happen on my old 11pro max, so it definitly is 14.3 related.

on the other hand, my 12 pro max found new ways to surprise me as it keeps forgetting the wifi passwords in my house.

I also sound like a robot from outer space to the person on the line and then it suddenly cuts of and the only way to get back on the line is a soft reset.

Agree with almost all on this thread

Thx for the advice. I have exactly same issue of unable to hear incoming calls on my new iPhone 12pro but outgoing is ok! Also incoming not working on all my Bluetooth headphones & car! Just did the network reset so fingers crossed but do hope Apple get a fix & do it quickly as I’m not keen to stand in a line at Apple store for an hour waiting to get in or wait on a call Odd this issue was not known in their testing
