Hello Puranc,

Welcome to the Apple Support Communities!

I understand that you are looking for microphone settings on your iPhone. If you are experiencing an issue with the microphone, please read over and work through the steps outlined in the attached article below. If you are not experiencing an issue, can you explain further what you are trying to do with the microphone or what setting you would like to adjust?
