Samsung has announced a new technology called Flex Titanium that will make foldable phones more durable. It launches in the upcoming Galaxy Z Fold 8 and Z Fold 8 Ultra. The company revealed it on July 15, 2026, ahead of its product showcase on July 22nd The Verge.

The core idea is simple: Samsung has added two thin layers of titanium underneath the screen. One is a titanium-alloy film that Samsung says is 20 times stiffer than the plastic film used in older foldables, yet thinner than a human hair. Below that sits a titanium plate that holds the screen more firmly in place. Together, these layers are meant to make the phone more stable when you hold it open and more resistant to breaking from repeated folding Samsung Newsroom.

Samsung also says the new design uses less battery power and makes the display sharper, but the company has not provided independent test results to confirm these claims. The announcement was first reported by 9to5Google on July 14 9to5Google.

What this change means

Flex Titanium is a modest upgrade to how foldable phones are built, not a complete redesign. Foldable phones have historically had two main problems: the visible crease where the screen folds, and screens that get damaged after being folded thousands of times. Samsung is addressing the second problem by reinforcing the screen from underneath with stronger materials.

It is important to note that this is not the same as the creaseless foldable prototype Samsung showed earlier in 2025. That was an early research project with no firm launch date. Flex Titanium is a real technology shipping soon on a specific phone. Samsung has not claimed it will remove the crease — only that it will make the phone last longer through normal use.

Using titanium in phones is not new. Both Samsung and Apple have used titanium in their premium phones for years because it is light and strong. The difference here is how thin the titanium layer is and how it handles the strain of constant folding. If the technology works as claimed, it could help foldables become as reliable as ordinary flat phones.

One other detail worth mentioning: Samsung is a major supplier of screens to Apple, and Apple is reported to be building its own foldable iPhone. If Samsung's new titanium technology proves successful, it could eventually be used in other companies' foldable phones too.

What we don't know yet

Right now, all the claims about Flex Titanium come from Samsung's own announcements, not from tests by independent labs or reviewers. That is normal before a product launches, but it means the real test will come after July 22nd. Real users will find out whether these phones actually last longer than previous foldables, and whether the screen improvements are noticeable in everyday use.
