Following the record-breaking success of its Galaxy Z Fold 8, Samsung must now find a way to make next year's foldable phones just as exciting. Reports claim the company is already working on it, supposedly preparing major display improvements.

Industry insiders are claiming (machine translated) that the South Korean tech giant is already developing a new kind of tech that could be implemented in next year's Galaxy Z Fold 9.
Called CTG (center-etched thin glass) or Hybrid UTG (ultra-thin glass), the technology thins only the central folding portion of the cover glass. By thinning this specific section while keeping the rest of the display thicker, the panel can fold more easily while gaining greater overall strength, rigidity, and durability.

Samsung Electronics is showing signs of accelerating the application of next-generation foldable technologies, including CTG, in response to major competitors. However, whether it will actually be adopted will become clear around the fourth quarter of this year.

According to reports, the CTG technology is still pretty new, and there are significant challenges that Samsung's team might have to overcome before it can be mass-produced.
One of the biggest challenges with this approach is that removing material from the center of the cover glass could create an uneven surface. As a result, the screen may not appear completely flat when viewed from some angles.
Still, continuing to push display innovation is important for Samsung as competition in the foldable market grows. With Apple expected to enter the segment with its first foldable iPhone next month, Samsung will face new pressure to maintain its position as a foldable smartphone leader.
Additionally, foldables are expected to keep growing into 2027. One of Counterpoint Research's latest analyses on the market projects that global shipments will surpass the 100 million mark, increasing nearly 30% year-over-year.

I hope we see it next year
Both of Samsung's Galaxy Z Fold 8 models proved a remarkable success for Samsung, with some regions already noting the devices have broken pre-order records. But with the iPhone Ultra just around the corner, the company will have to work even harder next year.
And to me, successfully developing, manufacturing, and adopting CTG could help Samsung's upcoming foldable phones stand out. It remains to be seen whether it'll be the defining upgrade of the next generation or a smaller but meaningful improvement. Still, I'm hoping we'll get to see it on next year's devices.
