Also, the root is needed
if you want more, then install the root, as written in the header. For MTC, the other will not work. Regarding the sound, I would try to tweak in the engineering menu, something like it says here -
Open the engineering menu (code * # * # 9646633 # * # *). Next, select the following menu items:
1. “Hardware testing”
2. “Audio”
3. “Volume”
4. “Voice” - Speaker
Raise in "NB" and "WB"
"Reciever" - the value of "UL Gain" - 164 (maximum), although they write that you can set 252, but I did not.
We see the indexes, this is the gradation of sound adjustment.
In the 6th index, we set 160 (this is the maximum, no longer gives), but probably, if you set the value of "UL Gain" 252, it will give more.
In your case, you would set everything to 160, but if you want to lower the volume with the buttons, the volume will not decrease.
At the bottom of the screen, press the “Set” button and reboot.
