Hindi Sadiq I am going to tell you how you can fix the microphone on that is not working on your xiaomi redmi 4 redmi note 4 or any other xiaomi device that you own.
I faced the situation myself several times, where the microphone does not work, for example when I have to use voice command in Google assistant is does not respond at all, or maybe I am recording something but it says something wrong with the camera.
Surprising thing is that the everything on the smartphone works and I am sure that I have not dropped my phone.
Which makes it clear that there is something wrong from the software side.
Here is you can fix your microphone
The first thing would be to restart the smartphone, I cannot count the number of times I have fixed problems just by restarting the phone.
Xiaomi makes nice devices, but, to be honest there software is not that great. Not just the microphone I have found sometimes the camera does not work and the simplest solution to fix it is to restart the phone.
Is restarting does not fix the microphone error. Try using external microphone, if you have got here phones which have got inbuilt microphones as well you can plug them in the 3.5 mm jack Android checking whether the microphone works or not
You can launch the recorder app to record something to know whether the microphone works or not.
If it works then there’s something wrong with the hardware, that is, the inbuilt microphone of your Xiaomi smartphone.
