Increase Mi 5s volume

[Piero_93]

Hi folks!
Is there a way to increase Mi 5s volume?
My call volume is so low... and also the bottom speaker isn't too powerful.
I'm using RR 5.8 (Android 7.1).
Thank you!

if you are trying to install from the app itself, note that it will not work for nougat devices. instead, there is a flashable zip made by @guitardedhero lying around on the forums somewhere (go search). or if you have magisk installed, you can just download and install the v4a magisk module.
