SEOUL — For seven generations, Samsung has been iterating on a simple but radical idea: what if your phone unfolded into a tablet? With the Galaxy Z Fold 7, the answer finally feels complete. The device features an 8-inch inner AMOLED display with no visible crease — Samsung achieved this through a redesigned hinge mechanism and a new ultra-thin glass formulation that bends at a 1.5mm radius without degrading. The outer display has expanded to 6.4 inches with a standard 20:9 aspect ratio, meaning the Fold 7 now feels like a normal smartphone when closed — a criticism that has dogged every previous generation.

The S Pen now stores inside the device, a feature Fold users have been requesting since the original. Samsung DeX, the desktop environment that launches when the Fold is connected to an external monitor, has received a major overhaul. The new DeX Pro mode runs a full Linux container alongside Android, enabling genuine desktop-grade development environments, creative tools, and enterprise applications.

At $1,799, the Fold 7 is still expensive by any standard — but it is arguably three devices in one: a flagship phone, a premium tablet, and a capable desktop computer. For professionals who travel frequently, the economics pencil out. Samsung expects to sell 15 million units in the first year, which would make the Fold line the company's second-best-selling premium device after the Galaxy S series.
