Wechat said that the other party's voice was very loud, and my voice was very small, so the other party could not hear clearly. What's wrong!

In this case, first of all, you should check the call volume of your mobile phone, because sometimes your mobile phone may accidentally reduce the call volume during use. You have to adjust it to see if your settings are normal. If there is nothing wrong with the settings, it depends on whether you don't understand and whether the microphone is too far away when you speak. If it is far away, what is the effect after you adjust the distance? If the above two possibilities are ruled out, then there is something wrong with your microphone, so the sound quality of your voice is too low for the other party to hear clearly, so you should check the microphone to see if there is any problem to deal with.
