Why it worked
The video likely worked because it showcased a new or desirable software feature (One UI 8.5) on a popular device brand (Samsung), appealing to users interested in mobile technology and customization.
Product placement
Samsung (phone manufacturer, provides the phone and its operating system interface, One UI 8.5). The One UI 8.5 interface is being demonstrated, which is a software feature of Samsung phones. Removing it would change the video's content as it is the primary subject of the demonstration.
