Why is the call microphone not working on iPhone?

I don't see the mic mode when I pull up my control center for my iphone 8, because I wanna try/use voice isolation mode.

I'm running on 16.5.1.

My phone seems only to work with speaker on. I cannot actually send or receive phone calls.

It won’t let me hear my video and I can’t work the YouTube video and I don’t know how to do the

To see or change Mic Mode on an iPhone, you must actually be on a call (Phone or FaceTime). Bring up Control Center and you will see Mic Mode in its upper right corner. Touch Mic Mode there to see (and change if you like) its setting. Mic Mode will retain its setting through subsequent calls.

Hi how did u fix the problem?

I want to know how to change my I phone mic mode because I can’t heard clearly when I’m talking to other people

Hi PastaKathy,

If you suspect a problem with your device microphone, check out If the microphones on your iPhone aren't working for some steps to isolate the concern:

"Clear the microphones

1. Remove any screen protectors, films, or cases from your iPhone.
2. Clear any debris from the openings of your iPhone."

and

"If people can't hear you on phone or FaceTime calls

1. Open the Voice Memos app. 
2. Tap the Record button , speak at the bottom of your phone, then stop the recording. 
3. When you play back the memo, you should hear your voice clearly.

If people can't hear you when you're using speakerphone 

1. Open the Camera app.
2. Record a video while speaking at the top of your iPhone.
3. Tap the camera chooser  to switch to the other camera. Then record another video while speaking at the top of your iPhone.
4. When you play back the videos, you should hear your voice clearly."

You can also test using paired or connected headphones that include a microphone. If those work and the other steps do not help, service is likely required and consulting Apple Support will be next.

Regards.

It sounds like you got your phone wet. It should be working once you shut it off and let it dry out.

You must turn the phone off immediately after it got wet if that’s the case if you did not get it wet then disregard a bad rainstorm that matters also. You’ll notice that first you cannot hear anything. As it sits there in the box with the silica packets, that will dry it out fast. After about a half an hour you make a phone call, you’ll notice you will barely be able to hear the other party. Although as time goes by you’ll be able to hear them better and better, the phone will actually get louder and louder as your phone dries completely.

Hi, I need help. My Kumon is so hard to do and also I can’t put a YouTube video with sound.

Bought recently a Iphone 15 and there it works.

So i think it had to do with the age of the phone for supporting that feature

your voice chanal is atomatically changed if its is nessary please manually adjust the microphone

I am having the same issue. It just changes by itself. I can’t get a clear answer from anyone. Did you get any help?
