TikTok (app): The video is about managing watched videos within the TikTok app. Removing it would change the video's topic. It ACTS as the platform where the user's watched videos are stored and managed. Removing it would change what happens in the video.nSamsung (brand): Several Samsung phones are shown, and the creator's bio mentions "FOR SAMSUNG AND IPHONES". The phones APPEAR as props to demonstrate the process. Removing them would not change the core tutorial, but would remove visual aids. The creator's bio also mentions "BAM UNITED TRADERS LTD FOR SAMSUNG AND IPHONES", implying they sell these phones, but the video itself does not demonstrate selling them.
