Can't hear received calls on iPhone 12 Pro Max

I mostly reboot the phone every few days. Works for now.

Rebooting has helped so far.

It seems to be when I am wearing my Apple Watch I haven’t had it on today and no problems. So i guess my watch may now be useless. Very frustrating

Be sure your screen protector is not covering the speaker at the top of the screen.

Have you tried this

Settings >general>reset >reset network settings ?

Interesting! Reset iPhone 12 Pro, no help. Can’t hear incoming calls. Reset Apple Watch too and calls can be now be heard.🤞

Hi C4hdt,

Thank you for posting in the Apple Support Communities. It sounds like you're having some trouble hearing incoming calls on your device since the latest iOS update, correct? If so, we'd love to see if we can help get the issue resolved for you. Would you mind answering a few questions to help us isolate the issue further?

Does the issue happen on every incoming call?

If you disable Bluetooth, does the issue occur?

Do you have a case or screen protector on the device? If so, does the issue occur if you remove it?

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

Please let us know if you have any additional questions. We're always happy to help.

Cheers!

I have same problem with my iPhone 12 Pro. When I receive calls and attempt to hear, I hear nothing but when I make a call on the same number, it works fine. Technically, it's the incoming call that I am not able to hear. After I reboot my device, It works fine for few days and then repeats again.

Tried everything like network reset, reboot device, restore with iTunes and the problem repeats after every 2 weeks. First I thought, it could be carrier issues, contacted my service provider and they investigated the issue, nothing is wrong from their end.

After everything, I decided to make a visit to the Genius Bar. They ran diagnostics, concluded nothing is wrong with the hardware which I really don't think. Came back home with disappointment. I am thinking to replace the phone using Express replacement service. Gonna check for a week, if the problem persists, I would go ahead with the replacement with Apple support. Really hoping that it turns out to be a software problem and Apple comes out with a fix in the next update. Someone else in the same boat lately??

This is very disappointing!

As mentioned somewhere in this conversation by me, I had the same issue with my new 12Pro. When I took it to the store it failed the sound test. They kept the phone and asked me to come after an hour. I think they ran a diagnostic test and fixed the issue. It happened once again and I turned off and on. Since then no issues. But overall I’m very disappointed with apple not fixing the issue as so many are having problems. I have been with apple from 4s onwards but my next one will be an Android Samsung. Had enough of messing around with this issue.

I have the EXACT same issues. I have never had these issues with my 11 Pro Max. ALSO...I cant make calls sometimes...it says called failed...I have to either put it in airplane mode and or reset the phone, then it works fine. This is crazy...

Check your screen protector. Mine was installed upside down so it covered the microphone which is at the top of the screen. Easy fix! Good luck everyone!

So it’s back. Had no problems for 2 days after changing the SIM card. Latest test is I have turned 5G off. So far so good. I’ll let you know how it goes

I will turn off my 5G as well, and see if that helps!
