iPhone 11 Pro Max call volume to low even on maximum

Hi there Doozers,

We understand you're experiencing an issue with the volume when on a call with your iPhone 11 Pro Max, and we'd like to see if we can assist.

First, do you notice this issue when using the receiver, speakerphone, headphones, or with every audio output?

If you only notice this with the receiver or speaker, remove any case or screen protector on the device, and test again.

Also, check for sound issues with any other apps. These steps may help: If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker

If you notice the issue with every sound output, make a call with FaceTime Audio, and see if the issue persists there. If you don't normally use this feature, give it a try now to help isolate the source of the call quality issue.

Thanks!
