I am using 11 pro max after updating 17.0.3 my ear speaker not working

Hello Rasvid,

Thank you for reaching out to Apple Support Communities.

Here are a few helpful steps to try first:

"If you want to try some more steps on your own

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

1. Remove all screen protectors, films or cases from your device. 
2. Check the opening of the speaker to see if it's blocked or dirty. On iPhone only, make sure the receiver isn't blocked or dirty. 
3. If necessary, clean the speaker or receiver opening with a small, soft-bristled brush. Make sure 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 can't hear any sound, or if your speaker button on the Ringer and Alerts slider is dimmed, your speaker may need to be serviced.
5. If you can 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 anything, or you hear static or crackling, then your network or reception could be the issue. Try calling again later or from a different location."

Additional details can be found here: If you can't hear any sound or hear distorted sound from your iPhone, iPad or iPod touch speaker

If the issue persists, it may be best to reach out to Apple directly. You can do so by going to Get Support

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

Cheers!
