In the video, the first thing you see is the composition of "Flex G", which folds the interior twice. However, then it passes with the "Flex S" design, which is more in line with what Huawei is currently using in Trifold, folding inward and out in the form of "Z".

To understand the basic difference, it is necessary to determine these foldable patterns. Z-Fold, as shown in Huawei Mate XT, is characterized by a screen raised around the outer part of the device when it folds. This means that the screen is always exposed. On the contrary, the G-Fold, as suggested by the SDC offer, includes an internal fold, similar to a book. This design puts the screen inside when it folds, providing protection.

Choosing a folding pattern has great effects on durability and user experience. External designs, with a smooth and larger display when detecting, are more likely to scratch and damage because the screen is constantly exposed. On the other hand, the interior designs, which give the priorities of the screen protection but may lead to a more compact external screen or require an additional external screen.

The SDC show, although it is not a direct confirmation of Samsung's future plans, provides a clear indication of the company's research and development efforts in foldable display technology. It provides the ability to monitor both folding patterns side by side compared to consumers and industry analysts. The potential "Galaxy G Fold" that adopts an inner slowdown mechanism that will put it in a different category from Huawei Mate XT, which can have an effect on consumer preference.

Personally, I believe that the choice between the internal or external fold is the issue of setting the priorities of screen protection for a large, ongoing screen. For those who use their devices frequently in difficult environments, the inner fold may provide more peace of mind. However, the attractiveness of the large, uninterrupted screen on the outer bird device is undeniable. The development of folding technology is likely to rely on how to balance the manufacturers of these competing factors.
