Samsung's new Flex Titanium tech explained: how is this better than previous foldables?

Following months of speculation, Samsung has finally announced the Galaxy Z Fold 8, Galaxy Z Fold 8 Ultra, and Galaxy Z Flip 8. The three devices have many exciting improvements, but the new Flex Titanium technology could be the one you’ll be the most grateful for in the long term.

Flex Titanium solves some of the biggest problems of modern foldables

For years, foldables have been plagued by questions about the durability of their internal displays and the seemingly omnipresent crease. Samsung’s new Flex Titanium technology aims to address precisely these two things, bringing several breakthrough improvements we’ve been waiting for a long time.

There are two key elements to the technology, and as its name suggests, they’re based on titanium. One is the new titanium alloy film, and the other is the enhanced titanium plate, which are essential to the display structure of the new Galaxy Z phones. Combined, the two allow the new phones to be thinner than before, but remain as durable as ever. 

The titanium alloy film is about 70% thinner than a human hair, but it is still 20 times stronger than the conventional polymer film used before. Thanks to this element, the crease remains less visible over time, essentially making the display last longer without being damaged.

Another effect of the new material is that the titanium alloy film doesn't stretch in the same way as the plastic polymer does, so it doesn't change its mechanical qualities as much and continues to support the OLED panel better over time.

Samsung is specifically proud of the titanium plate, which is the reason the display gets a flatter and more uniform surface. That’s why the crease is less visible to begin with, not only over time. The new materials strengthen the support of the display, which helps absorb pressure and impact.

It opens better

Flex Titanium is also part of the reason opening the new phones feels better. The new structure helps with the balance of the redesigned hinge mechanics, display tension, and magnetic force, leading to a smoother, lighter, and more natural opening of the phones.

My colleague Victor said he’s finally in love with how the Galaxy Z Fold 8 unfolds, after hating opening the Z Fold 7. While the new hinge is not the only reason for his claim, it certainly adds to the experience.

Samsung also says Flex Titanium provides an immersive viewing experience by allowing users to fully enjoy the quality of the display. The company says the technology is the result of it listening closely to the consumer feedback from its earlier foldable devices.
