As for the Sound - Go to

Settings
Volume

and check equalizers...

Screen resolution is set to auto in my case. In Your case you have to play with screen settings.

You have to play with DPI...

First of all disable

[rawdisplay]
screen_xy="auto

by putting ; in front of screen so it looks.like this

[rawdisplay]
;screen_xy="auto

; is on/off switch


In your sys file play with it. Try different.

dpi=640 is in my (Note 8) for your device try something else. Keep increasing or decreasing by 40

Here you have four different options

[rawdisplay]
dpi = 640
base_dpi = 240

[rawdisplay]
dpi = 640
base_dpi = 320

[rawdisplay]
dpi = 480
base_dpi = 240

[rawdisplay]
dpi = 320
base_dpi = 120
