Hong Kong – November 5, 2026 – A foldable smartphone is more than a display that bends. Its display, hinge, materials, internal architecture and software must work together to deliver an experience that feels natural in everyday use. Across eight generations of Galaxy Z devices, Samsung has refined that engineering challenge—building a portfolio of foldables that brings together hardware, software and durability.

That progress is visible in the Galaxy Z Fold8 Ultra, Galaxy Z Fold8 and Galaxy Z Flip8. Each model reflects years of learning about how people carry, open and use foldables, and how to make the form factor more useful without treating portability, durability or performance as competing priorities.

Precisely Engineered to Be Slim and Light for All-Day Comfort

Making a foldable thinner and lighter requires more than reducing the size of individual parts. Samsung engineers the display, hinge, materials, battery, thermal system and internal architecture together, carefully balancing how components fit and how forces move through the device.

Galaxy Z Fold8 measures 4.5 millimeters unfolded and 9.7 millimeters folded. Weighing 201 grams, it is the world’s lightest fold[1] - 52 grams lighter from the 253-gram Galaxy Z Fold5 launched in 2023. To achieve this design, Samsung reexamined approximately 270 components and more than 180 types of auxiliary parts, refining designs and layouts across the device.

Flex Titanium, used in the displays of Galaxy Z Fold8 Ultra and Galaxy Z Fold8, illustrates this system-level approach. It combines a titanium-alloy film beneath the OLED panel with a precision-engineered titanium support plate. The film is just tens of micrometers thick—roughly one-third the width of a human hair—while the support structure is designed to balance strength and flexibility through repeated folding. Together, these innovations enable a display module that is 10% thinner, with improved flatness and reduced crease visibility.

Samsung selects materials according to the role each part must perform. Advanced Armor Aluminum helps provide strength in a thin, lightweight frame, while internal design and material choices support thermal management. Space recovered through this work can be used for other components, including the 5,000 mAh battery in Galaxy Z Fold8 Ultra.

A Larger Canvas, with Apps Designed to Make More of It

A larger display creates value when people can use it naturally. Across generations, Samsung has refined the relationship between the foldable form and its software, developing experiences for multitasking, productivity, creativity and AI.

On Galaxy Z Fold8 and Galaxy Z Fold8 Ultra, Multi Window lets users run up to three apps in split-screen and resize the layout to suit the task. Pop-up View adds movable, resizable floating windows, allowing users to work across up to five apps. Rather than limiting the large display to a single view, these tools let users arrange their workspace around what they are doing.

Samsung has also worked with platform and app partners across generations to help apps adapt between the cover and main displays. The goal is to make the transition from quick interactions when folded to a larger workspace when unfolded feel natural. On the latest Galaxy Z series, the foldable experience also brings together Galaxy AI and features designed for immersive viewing, content creation and everyday use.

Eight Generations of Foldable Experience, Built for Everyday Confidence

Durability is not defined by a single component or test. The display and hinge must work together through repeated folding, while the frame and internal structure help protect the device during everyday handling.

Samsung validates the latest Galaxy Z series through more than 100 reliability validation tests covering conditions including drops, repeated folding, pressure, moisture and debris. The tests are designed to evaluate how the complete device performs under a range of stresses and help identify potential issues before products reach customers.

This complete-device approach builds on lessons from successive generations of foldables. By considering how materials, components and structures work together, Samsung engineers for a balance of portability and reliability in everyday use.

A Galaxy Z Portfolio Shaped by Different Needs

Eight generations of foldable experience have also shown Samsung that there is no single definition of the right foldable. Galaxy Z Fold8 Ultra, Galaxy Z Fold8 and Galaxy Z Flip8 offer distinct form factors and experiences for people who prioritize different combinations of large-screen productivity, everyday versatility and compact portability.

Together, the Galaxy Z lineup reflects an ongoing engineering effort: refining the hardware, shaping software around the foldable canvas and validating the complete device. It is a story of accumulated learning—and of turning that experience into foldables designed for how people use them today.
