Samsung’s first foldable, the Galaxy Fold, was launched in early 2019. It was the results of a really lengthy improvement course of, explains Jason Noh, a developer within the Show Group underneath Samsung MX.
Work on foldable expertise began way back to 2008. To place that in context, the Samsung Galaxy, the corporate’s very first Android telephone, got here out in 2009. 2008 was the 12 months of the Pixon and Omnia, early touchscreen-based smartphones.

“Our group needed to create a high-quality show that could possibly be folded however resistant to clutter — which meant we needed to change the plate supporting the show,” explains Noh. One of many early developments was the event of Stress Delicate Adhesive (PSA) that helps the show when folding in numerous circumstances and environments.
One other main materials development was the Extremely Skinny Glass (UTG), which was launched with the primary Galaxy Z Flip in 2020. UTG has grow to be a typical part of folding shows. “With the adoption of UTG, we had been in a position to ship a clearer show — full with a premium feel and look that had but to be seen on a foldable smartphone. UTG has been used ever since,” says Noh.
Quick ahead to 2024 and the Samsung Galaxy Z Fold6 and Z Flip6, which introduce a so-called “Defend Layer” construction. A key part of that’s yet one more revolutionary materials, Shear Thickening Fluid (STF). STF adapts to totally different quantities of strain in order that it resists deformation from impacts. This has made the 6-series foldable shows essentially the most sturdy but.
The newest Galaxy foldables • Carbon fiber and metallic plates
Leaping again in time to 2021, the Galaxy Z Fold3 and Z Flip3 had been the primary foldables to characteristic water resistance with a excessive IPX8 score. This was executed utilizing a rubber band that runs across the perimeter of the show and seals it towards liquids. And again to 2024 with the Galaxy Z Fold6 and Z Flip6, that are the primary foldables with particle ingress safety, IP48.
This was achieved with improved sweeper expertise – small brushes that hold particles from getting into the gaps between the entrance of the gadget and the hinge.
The S Pen stylus is one other piece of iconic Samsung tech and it made sense to marry the Fold and the S Pen with the Galaxy Z Fold3. Simpler mentioned than executed because the metallic plate used as display backing in earlier fashions created interference that tousled the S Pen digitizer.
As an alternative, Samsung needed to change to a carbon fiber plate. That also wasn’t sufficient – the digitizers are on the left and proper aspect of the show they usually had bother detecting the S Pen within the folded a part of the show. Builders created an answer to this utilizing “refined calculations”.
“As a pioneer of the foldable smartphone, our group has amassed data and expertise on what customers anticipate from this kind issue. To satisfy these expectations, we is not going to cease our journey towards the right show expertise. The Galaxy Z sequence will continuously bear enhancements to show Samsung’s title as a trailblazer in foldable smartphones,” mentioned Noh.
