In the video, an unseen narrator opens a bag of Lipton lemon-flavored green tea - normally, you would never open your tea bag, so it's unclear what prompted this. The narrator proceeds to pour out the loose tea and begins to point out tiny shapes, claiming are "worms," despite nothing moving over the course of the video. The narrator also says it's not a fluke, as "several bags and several boxes" that they've opened are the same.
The Camera Control (don't call it a button) was triumphantly unveiled by Apple last year alongside the iPhone 16 family. It was an important part of the launch presentation, and even got its own ads. However, it seems like not many people are actually using it - at least that's what a new rumor on Weibo claims. Do however note that this information doesn't come from a source that has any sort of track record, so accuracy isn't a given.
