I’m not able to hear the sound when someone calls me

A large number of users are reporting this problem on different iPhone models. I believe I have tried all of the suggestions that have been made in the responses to these low volume reports. I have to use the speaker to hear most phone conversations. I have reported this issue on the Apple feedback page. It would be helpful if you reported the problem there as well. That's the best way to report this issue. Apple does not monitor this forum.

iPhone 8 / iOS v13.6

Hi!

Have you tried restarting your iPhone then checked if the issue still happens?

If yes, you may check this other steps below for more information: If you hear no sound or distorted sound from your iPhone, iPad or iPod touch speaker.
