I second this inquiry. Model S23 Ultra, same problem. I've searched for years I started reading all related Apache legal notices for any hint, infact, this is the first time I've ever, with my own 2 earballs heard or witnessed anyone even come close to stringing the words "Quick Share" and "Hidden Setting" in the same article let alone the same sentence. I was going down a rabbit hole on Github and Reddit and it seemed like they were getting at the idea that every phone has its own password and it takes some searching of internal code somewhere, kind of a need to know basis or something. I'm assuming there are probably "bad actors" that may or may not be able to do nefarious things with whatever information that could be aquired through the "hidden" settings that are available. Maybe Network Pen-Testing or mild DDoS style directed attacks on nearby unsuspecting targets. I could be totally wrong as I'm no network expert but I would like to know what's in that menu if only to be aware of my own devices vulnerabilities.
