[Q&A] How can I access to engineer mode? (or something similar)

Since I bought my Xiaomi, speaking into the microphone is too low.  But nothing compared to when I wear headphones, nobody really listens to me!.  I have to stick the microphone of the headphones to my mouth so that people can hear me.

I have seen that in devices with MTK you can access the Engineer Mode and be able to modify the audio gain values, but in the Mi A3 I have only been able to enter the Phone Test and it does not solve anything at all.

My question is, how can I access the Engineer Mode on my Xiaomi Mi A3?

And if that option does not exist, how can I increase the gain volume of the microphones?  I hear terribly low on calls, and even more so when I wear headphones.
