It looks like a joke article about the new iPhone, but with a humorous and misleading title! The "button" in question is probably just a weird shape or feature on the phone that's been Photoshopped to look like a button.

The real kicker is the phrase "control your leverage"... which sounds like a business term, but also implies something more... interesting 😅. I'm guessing it's supposed to be funny because it sounds like it could be a euphemism for something else entirely!
