Timon-Azure-Shark Oh, thank you for your very good explanation.👍 I misunderstood - I did not think of using a launcher, I thought he changed the icon of the app itself, for example in the .apk-file and reinstalled the app or similar... Oops! 🤔😅
I will think about using the nova launcher, but I always liked the vanilla launcher Samsung One UI 1.1 gives me.
Thank you, and have a great Wednesday evening! 🌈
