iPhone 13 pro voice cuts and the other person can't hear me

I'm using my iPhone 13 Pro Max with Ghostek nautical waterproof iPhone 13 pro max case. I'm having the same issue meaning voice cuts and the receiver can't hear me. My phone was tested by the mobile Service provider and the Apple support including the Apple in-store Techs. They ruled out there is no issue with the phone and requested to change to a new SIM too. Replacing to a new SIM card did not resolve the issue. The issue was resolved only after I removed the above waterproof case.

I noted this same issue on iPhone 13 Pro Max generally with Waterproof cases.

I also have the mic cut out when used on speakerphone, due

to noise cancellation of sound coming out of speaker.  iPhone 13 pro purchased 11JL22 from

Verizon.  Zag screen protector and speck

presidio 2 case (have only ever owned speck cases). 

The cut out was at its worst when talking to people with a

lot of background noise.  My sister on

her wireless land line became my worse test case.  (when I called her on her iPhone 12 the cut

out wasn’t as bad)  Our 2 test cases (for

worst and repeatable cut out) became running water in the sink and Crinkly bag

(while I just counted aloud).  As it

turns out removing the case 90% solves the problem.  Running water was reduced to no cut out.  Crinkly bag caused garble but was still

understandable till the bag drowns out the call.  This performance was similar to my previous

iPhone 8.  Thanks ERSSERSS for posting 15

times about removing the case. 

There are no posts on what case works… Also frustrating is

the Apple store and Verizon “looking at you like you have a third eye in the

middle of your forehead” (credit bemrik3) when you describe the problem your

having with your new $1000 phone… knowing 1000’s of people have already

complained about it.

I was able to produce no case performance by removing (with

a dremel) from the inside, all parts of the case that contact the bottom

stainless flat of the phone (bottom radius’s of case not modified).  The ovals for the mic, lightening and speaker

were also enlarged.  The front and back

edges and the web between the ovals are still there. ie if you drop the phone

of a flat surface the case will still prevent the phone from contacting.

Note: before I went to the dremel I tried to isolate speaker

sound from mic with a 1mm thick mastic (soft rubber) between the case and the

bottom stainless edge of the phone.  This

had no reduction in cut out.  (ovals for

mic, lightening and speaker were open same size as case)

Oh, but by the way, I don't have a problem using 5G. My phone works fine now that I've taken off the waterproof case that was blocking the 3 microphones.

I have a fix!

I just contacted apple support with the same issue on my iPhone 13 Pro. (My voice was cutting out for the person on the other line if they were also speaking or they had any background noise.) This resolution worked for me:

1) check audio: Go to Settings > Sounds (or Settings > Sounds & Haptics), and drag the Ringer and Alerts slider back and forth a few time

2) Press and quickly release the volume up button, press and quickly release the volume down button, then press and hold the side button. When the Apple logo appears, release the button.

3) reset networks settings. Go to Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.

That was it. Hope other people find this helpful too.

Hello everyone.

i just want to share the solution i figured out which greatly helped me, hopefully it’ll be a big help to everybody struggling with the speaker problem; being not heard by the other party when using the speaker for calls.

during calls, slide down the top of your screen to open Control Centre. You will see the a setting “Mic Mode”, i saw in my setting that its “Voice Isolation” i turned it to wide spectrum or standard. And it immediately worked! Hopefully it will work. I have attached a photo of what im referring to.

cheers

Yes, the case can be the problem. If it's a waterproof case it covers all the mic holes. If you remove the case and still have the problem then it's another issue too. I removed my waterproof case and my problem was solved.

I was on a follow-up call with Apple support and we removed the phone case and that seemed to have fixed the problem (we think) which also seems to be a solution that some have had in this forum. It turns out that the two cases I ordered for this phone both sorta cover the microphones that are on either side of the lightning connector. Removing the case seems to have made the microphone very clear and not cut up. I will be ordering a different case to see what happens but I am cautiously optimistic. So my question to everyone else having this problem: does your phone case cover your microphone dots at the bottom of your phone? Perhaps it's not an Apple problem at all but a case problem.

UPDATE: Apple sent me to Best Buy to diagnose the speaker phone problem. The tech guy said, "That sounds like a software problem Apple needs to fix with an update." Then he looked and said, "Wow - they just pushed out a new update!" So I downloaded it and have made several very long calls using only the speaker phone, and everyone says I sound great and my voice has not cut out or been garbled. I'M HOPEFUL THAT IT'S FIXED!

I BROKE THE CODE!!! At least for me. I finally realized that the "waterproof" case I bought from Amazon covers all the microphone holes so that no one on the other end can hear you except a very muffled voice from you. I took it off, called a friend, problem solved! I tried every suggestion made in this thread before figuring this out. Check your case and see if it's covering your 3 microphone holes. Good luck!

i had the same problem and found the case I had bought was muffling the microphones. Just in case, take the accessory cover off if you have one and call somebody. Also check for iOS updates. I did that too before I found the cover was my problem.

My iPhone 13 Pro would cut out when using the speaker as well. I went to the apple store for help and they finally concluded it was my case. Try your call on speaker with your phone not in the case and see if this helps. I bought a new Apple case and I have no problems now.

Hi, I just got a new iPhone 13 Pro Max and it's been a nightmare with the audio cutting out from Day 1. Every. Single. Call. Doesn't matter where I am or with whom I might be speaking. I've had the phone for just under a month. For long stretches during conversations, my phone's audio will cut out so that callers can't hear me at all. At first I thought it was the other callers, and then I thought it was the speakerphone on my phone (as some other people have thought on this forum). I use my speakerphone A LOT in my business. I tried removing the case, which had no effect, and resetting my Network settings, which required entering in all my passwords again. I then tried using only my car's bluetooth, and then I tried using only my iPhone earbuds. Nothing changed. I set up a Genius bar appointment for today, but then I read on this forum that many people had their phones swapped out, only to have the same problem. Since noise cancelling cannot be turned off anymore, that was not an option for me.

This morning I had the idea to eliminate the 5G option on my phone. I went into Settings, Cellular, and Cellular Data Options, and Set Voice & Data to LTE. Then, I set my phone to Data Mode "Standard." I had already turned off Data Roaming earlier this month to see if that did anything.

For the last 3 calls, the problem hasn't reappeared. I currently have Data Roaming toggled off, Voice & Data set to LTE, and Data Mode set to Standard. I hope this helps someone!!!!
