[lg461]

how can i change quick panel color?

i dont have that feature in developers options.

also dont have this ”styles & wallpaper” feature from long pressing home screen.

ive tried with "change quick panel color" in quickstar via nicelock, it doesnt seem to work, loading endlessly.

also tried with theme park via nicelock, its also loading endlessly.

phone: samsung a40

android: 11

one ui: 3.1
