Can't hear received calls on iPhone 12 Pro Max

I have tried the following and one of them solved the problem - for the last 2 weeks it is working fine:

1. Reset network settings (this did not help by its own - temporary solution)
2. Remove all BT devices and add again when needed
3. Turnoff VoLTE

I do not have 5G in my region yet. Therefore I do not see the option all together. The reason I am writing this is because some as written that this happens when 5G is turned on, but seems like it was not the case for me.

This is for sure either a GSM radio issue or an OS issue. Hopefully it is the latter and Apple pushes a patch for it.

Hello everyone. I am facing the same issue like i mentioned earlier. I have been going to the network provider and apple store to fix this issue as it is soo annoying. But i have recently got a solution for the issue. Try to disable VoLTE (voice over LTE), its in the settings under cellular settings. It worked for me. After i turned it off i am getting incoming calls and its audiable. I hope its works out for everyone experiencing the similar issue. Anyway i am going back to Apple store to see what they can do about this. I will update once its done. Because last time i did mention to the technical support guy if whether its the VoLTE. But he said that shouldnt be the reason. Anyway it worked for me. If it works out for anyone else please do reply. Goodluck!

So when the 5G is turned off or to 4G and data set to Standard I don’t have a problem. Just annoying fax noises from time to time. But at least I can hear people when they phone me. Seems 5G is an issue. The next test will be to start adding my Bluetooth devices back and see if it returns. I’ll let you know.

So after all this I phone my network provider Vodafone and they tell me they have a fix and that it’s a network problem. They change a setting at their end you restart your phone and then it’s all good. So far it’s been fine but it’s only been 24 hours.

I talked to my service provider they said it is a bug in iOS around switching between 4G and 5G

Go to

Settings>Mobile data>Mobile data options>Voice & data. Choose 4G

This has eliminated the failure on my 12 Pro for now.

Of course you can argue that it is a 5G phone and it should work, but know one has ever won an argument with apple😔

Hi,

I had the same issue as yours and I tried turning off the VoLTE.

To check if its Turned off go to Settings > Cellular > Cellular Data Options > Voice & Data > VoLTE.

Try this if not already. It worked for me :)

Thanks

If you go to Settings > Cellular > Cellular Data Options > Enable LTE, and change the setting to Data Only, does the issue still occur?

I tried this step and the problem is solved, I hope it will not occure again

Fix from An authorised apple service providers in NEW ZEALAND... off the record conversation..

turn off 5G for voice. Some cell towers designed to only ping data and not set up for voice. Phone catches onto the 5G cell towers but because they’re not set for voice, you won’t hear anything.

cheers

Since my cellular provider - Vodafone - tweaked something at their end I’ve had no further problems. Talk to your network provider. I spent months trying to resolve and they fixed it with one phone call

I am on the phone now to Apple and they're telling me its because of the SETTINGS / MOBILE / MOBILE DATA OPTIONS being on Roaming On - Voice & Data being on "5G Auto" and this could be the issue as my SIM card plan isn't on the 5G plan...

I don't ACCEPT this explanation of theirs because I could hear all incoming calls just fine before(and I don't have a 5G plan) and now for a week I cant hear any incoming call. All incoming calls sound dead !!! Maybe the new iOS 14.4.2 is the CULPRIT

Mine seems to relate to my Iwatch series 4. Now I’ve unpaired it I’m not having any problems and can hear callers when they phone. I’m going to give it a couple more days and then pair my watch again and see if it happens again

Mine has been doing this as of this morning as well.

I’ve got the iPhone 12 Pro Max and after trying almost everything I think I may have found a fix for my iPhone!

Try Settings > Mobile Data > Mobile Data Options > Voice & Data > Enable VoLTE

Hope this helps!

I had the same issue with my iPhone 12 Pro Max. I would reset my network settings. Shut the phone off and that seemed to help but then it would start again. Go to the Genius Bar, if you can. For me, it was a speaker issue and they replaced it on the spot. Hope this helps! Good luck!

I have been experiencing this problem for last few days . Just been on with Apple support and they advised go into

settings >general>reset >rest network settings .

I have just done this and it works . So praying it lasts

I have the iPhone 12 for 2-3 weeks and having the same problem as everyone else here! Have just trawled through 6 pages, seen one? reply from Apple and have tried a few of the suggestions from other unhappy customers.

My phone is linked to my previous iPhone 7 as I have given that to my kids, I switched off ‘allow calls on other devices’ and that seems to have worked. I have also now changed the mobile data options > voice and data to 4G only as per ppls suggestions that 5G is the problem.

Hopefully this works as it is obviously incredibly frustrating having a phone that is 100% fine to make calls on and not working to receive calls at all, so obviously NOT a cover or speaker problem Apple!

Please note these 6 pages of the same problem and organise a fix to iron out this bug!
