Are there changes on this update besides from TWRP?
Hopefully smart lock is fixed
This ROM may potentially solve some issues as I stopped using XMLs which come from S8's CSC package (starting from v5.5 there are original XMLs only, just unencrypted - see changelog)
dolby is not working in this rom? Any idea how to fix.??? ;( please help
Personally I do not use sound mods at all, but (reportedly) Viper4Android works (I mean V4A Magisk's module). This ROM contains stock (enforcing) kernel, so you can try with a custom kernel (but I have no idea which one I should recommend in your case)
