Samsung has announced the Galaxy Z TriFold, a foldable phone comprised of three ultra-thin (~4mm) panels and two sets of hinges, that unfolds into a 10-inch tablet. When closed, it resembles a standard smartphone with a 6.5-inch display that is 12.9mm thick. Because the main screen is so large, Samsung has created a "standalone" version of Samsung DeX, meaning it can switch to a PC-like desktop mode without attaching an external monitor. But users can still attach an external monitor to create a dual-monitor desktop setup. Standalone Samsung DeX works with or without a Bluetooth keyboard and mouse. The three panels fold up in such a way that the larger display is fully protected. This means that there is a wrong way to fold the phone, but the phone has automatic vibrating and visual alerts to keep you from doing that. The Galaxy Z TriFold is powered by a Snapdragon 8 Elite for Galaxy chip, triple-camera system with 200 megapixel main camera, and a 5,600 mAh battery system with 45W wired charging and 15W wireless charging. As with Samsung's Z Fold phones, it has "front" cameras on both the inner and outer displays. It's rated IP48 for dust and water. It ships this month in South Korea, and Q1 in the US. US pricing has yet to be announced.
