iPhone 12 breaking up when using speaker mode

Hello MeandUFS,

Thank you for reaching out to Apple Support Communities.

These steps may help:

"If you want to try more steps on your own

If you prefer, here are some more steps you can try on your own. After following these steps, you might still need to contact Apple Support to discuss service options.

1. Remove all screen protectors, films, or cases from your device. 
2. Check the speaker opening to see if it's blocked or dirty. On iPhone only, make sure that the receiver isn't blocked or dirty. 
3. If necessary, clean the speaker or receiver opening with a small, soft-bristled brush. Make sure that the brush is clean and dry.
4. Go to Settings > Sounds (or Settings > Sounds & Haptics), and drag the Ringer and Alerts slider back and forth a few times. If you don't hear any sound, or if your speaker button on the Ringer and Alerts slider is dimmed, your speaker might need service.
5. If you hear sound, try making a call with your iPhone and turn on speakerphone. On iPad or iPod touch, make a FaceTime call. If you still can't hear, or hear static or crackling, then your network or reception could be the issue. Try to call again later, or from a different location."

More details can be found here: If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker

If the issue persists, we would recommend getting back in contact with Apple.

You can do so by going to Get Support

They will take a closer look and check on available options.

Cheers!

Search these forums and you’ll see that a bunch of us have had this issue and tried EVERYTHING, and nothing works. Apple refuses to acknowledge it. And it doesn’t happen with EVERY iPhone so they can get away with acting as we’re the crazy ones and it’s not the phones. I have an iPhone 13 that I no longer use, instead I went back to my iPhone 8 because it was stressing me out every time I used my speaker phone.
