Huawei's Mate XT Ultimate is a phone that does not flip or fold, at least in the way of its Samsung or Google contemporaries. You could say it collapses, really, across two hinges, from a full 10.2-inch diagonal rectangle (about a half-inch short of a standard iPad) down to a traditional 6.4-inch rectangle phone slab. There's also an in-between single-fold configuration at 7.9 inches. And there's an optional folding keyboard.

This phone, which Huawei calls a "trifold," would cost you the USD equivalent of $2,800 (19,999 yuan) if you could buy it in the US. Most notably, the phone launched just hours after Apple's iPhone 16 event. As noted by The New York Times, Huawei's product launches are often timed for maximum pushback against the US, which has sanctioned and attempted to stymie Huawei's chip tech.
