CES 2019 arrived with foldable phones at the centre of every conversation, and for the first time in years the question of what a phone could be felt genuinely open again.
Royole had beaten Samsung to the punch with the FlexPai, a device that folded outward and ran a version of Android. It was rough around the edges. The crease was visible. The software felt unfinished. But it was real and it was shipping, and that alone was enough to make everyone in the industry pay attention.
Samsung came to Las Vegas with a preview of what it was calling the Galaxy Fold. The demonstration was carefully controlled. Journalists watched the device open and close from a distance, the screen unfolding from a compact phone into something closer to a small tablet. The hinge felt deliberate, mechanical, satisfying in a way that photographs could not quite convey.
Standing there thinking about it, the obvious question was whether this actually solved a problem anyone had. Phones had converged on a fairly settled form. The slab of glass and metal had won decisively over every other design. People knew how to use them. Pockets and cases and habits had all adapted. Folding changed the geometry in ways that were interesting, but interesting is not the same as necessary.
The counterargument was that screen size had always mattered and always involved tradeoff. Larger screens were more useful for reading, watching, and working. Smaller devices were easier to carry. Folding was, in theory, a way to have both. Open the device and you had a proper screen. Close it and it fit in your pocket.
The price Samsung was rumbling around was close to two thousand dollars. That was a significant bet that people would pay a premium for the form factor before it had proved itself. It was also a recognition that first-generation hardware of this kind was expensive to build.
What I kept coming back to at CES that year was the display technology itself. The flexible OLED panels being demonstrated were genuinely new. Whether the phone form factor was the right first application or not, the underlying capability of bending a display without breaking it felt like something that would matter for longer than any single device cycle. The future was being shown here even if the exact shape of it was still being figured out.
