Samsung may use titanium backs on Galaxy Z Fold 7 and first tri-fold phone

Samsung is once again pushing the boundaries of smartphone durability and innovation. Fresh leaks suggest that the upcoming Galaxy Z Fold 7 and Samsung’s much-anticipated Tri-Fold phone will feature titanium backs—a major upgrade aimed at improving durability without increasing weight.

According to a report by The Elec, a Korean tech outlet, Samsung plans to integrate titanium backplates in both the Z Fold 7 and the Tri-Fold models. Unlike earlier approaches that used titanium in the frame, this time the titanium will be applied to the outer back panel, especially around the hinge and foldable display area, enhancing structural integrity under heavy usage.

Why Titanium?

Titanium is celebrated for being both lightweight and extremely strong, making it ideal for foldables that undergo frequent bending. While Apple has previously used titanium alloy in its iPhone frames, reports indicate they may revert to aluminum with the iPhone 17. Meanwhile, several Chinese brands have also explored titanium to bolster the strength of their flagship models.

Expected Launch Timeline

The Galaxy Z Fold 7 is expected to launch in early July during a live event in New York, with strong rumors suggesting the Tri-Fold phone might also be unveiled at the same event.

A History of Material Innovation

Samsung has steadily evolved the materials used in its foldables. The original Galaxy Fold and its successor featured stainless steel backplates, while later models shifted to carbon fiber for improved weight and strength balance. This new titanium integration is the latest in that evolution.

However, the leaks also mention one notable omission—the Galaxy Z Fold 7 is unlikely to feature an S-Pen digitizer, meaning no built-in stylus support like in previous iterations.
