the sound in all aosp ROMs is the same, you can use V4A to increase the quality of the speaker.(sorry for my bad english, and grammar. I'm not good at it)
Is there a bug with the sound quality in ArrowOS?
That bug makes the bass not so good anymore, the speaker quality is really bad, it's not as good as OneUI
I encountered it in LOS
and one more problem, is there any error in screen brightness?
hope you to reply soon
Brightness is working fine , can you explain more ?
