Playing mobile games, then suddenly someone calls you? You don't have to worry because there is new feature called 'Smart Pop-Up View'.
Since I'm new to Samsung's One Ui skin (My very first phone from Samsung is duos something with touchwiz ui), I don't know if high end phones have this feature preloaded on their settings.
To turn this feature, go to Settings > Advanced Features > Smart Pop-Up View > Select Applications
Once displayed on screen, You can adjust the opacity of window display, minimize , expand and delete current window.
