Booster volume galaxy A02s

hello all

my phone is galaxy a02s. I wanted 1 bit volume booster , so I installed an app from googleplay (I didn’t find the same on F-Droid ) that does exactly what I want , although it has ads , but on the other hand as I have installed Blokada 5 , I don’t see them … .

I was wondering how the app can increase the sound of my phone without root? !

I’m interested in boosting the sound of my phone without using any app, or one that is open source.Is this possible?

thanks :slight_smile:
