Hex Plugin
This is not a separate app, this is a plugin that needs Hex Installer app to be able to use it.
You can customize your Samsung oneui with beautiful dark theme and customized coloring option for app icon & customized system icon's.
This plug in is for those that like colour, includes custom blend style qs icons, dialog pop ups, keyboard, message bubbles etc. Theme colours rely heavily on your selected primary and accent colours. Pick your own two colours and see if it blends.
If dont like the blend style pop ups and prefer actual gradient then select to use note ui and experience a gradient style in place of blend backgrounds. It is like two styles wrapped up in one colourful package.
