Hi don't know if this is the right place to ask but anyway, on my s22 ultra when I have a notification and pull down the quick access panel it's just a round white icon no matter who it’s from, any help would be much appreciated thanks in advance!
Not sure if you're still using the default theme but I've found that by going to quick star in the quick panel and re-applying it then that fixes itself and so you might be able to go back to using a custom theme (or at least I'm using a custom icon pack again rather than a full theme)
