Samsung's new Galaxy Z TriFold is basically a limited edition experiment you can buy. They are making it in crazy small batches, reportedly just three to four thousand units so far, because building a triple-folding phone without it breaking is a manufacturing nightmare. Ramping up production would mean way more defective units and higher costs, so they are intentionally keeping volume super low, which is why those initial batches sold out in minutes. They might not even hit forty thousand units globally.
This super-cautious approach hits the specs sheet, too. To keep component costs from exploding, the TriFold uses last year's Snapdragon 8 Elite chip, not the newest model. A prototype even had four cameras, but the final product...
