How to use Code:

• https://www.youtube.com/watch?v=MIUB2myx7Tw&t=362s Thanks to channel: Viettablet
• Open File V1.5.5 with Raw

At the Final Version: I will not debloat more, or change any code, because it will lead my phone to unconvinience situition, but I promised, I checked carefully every application in phone. Only mistake is missing hearing Adjust:

• Use Find (CTRL+F) with keyword 'hearingadjust' and using command: pm install-existing to re install it again.
• I'm sorry for this
