Microphone not picking up sound

My microphone isn’t capturing sound when I record an audio recording, voice notes, and people can’t hear me over the phone, but when I record a video , It catches low quality sound and I’ve cleaned my microphone but it’s still not catching any other sound, but siri can hear what I ask her but people can’t hear me over the phone. I don’t know what to do anymore, I’ve tried rebooting and switching off noise cancellation but still nothing
