Android Central Question
There is a tol much problem in mi a1 by sound emplifire.. Can we disable sound emplifier by our use.. Mic volume is too low in hd call
Welcome to Android Central! If the main problem is that people can't hear you well when you're on a call, then it's unlikely to be due to the amplifier. There might be a problem with the mic itself. Make sure the mic opening isn't clogged by lint, or blocked by your case.
I'm not aware of any app that can boost the microphone's sensitivity. In the US, if you were to call the emergency response number (911), the emergency response service would be able to locate your phone via GPS and send help to your location. Do you have a health condition that might make it difficult for you to speak?
