Galaxy Z Fold series
A phone that folds is called a foldable. Foldable smartphones have a central hinge and two folding sides, as opposed to bar-type smartphones that have a single body. The pivot functions as the primary axis for opening and shutting the phone. With every new release, Samsung creates a groundbreaking hinge design by incorporating novel, state-of-the-art technologies into the hinge mechanism of its Galaxy Z Fold series.
Samsung has also kept the Galaxy Z Fold series thinner so that it may be taken about wherever and whenever needed.The Galaxy Z Fold series’ elegant shape and unique hinge design, which are now even more durable, compact, and thin than before, were examined in detail by Samsung Newsroom.

The Inception of Foldable Telephones: Clying and Uncloying

Users’ needs are evolving along with their increasingly diverse lifestyles. Samsung releases innovative technology every year in response to these advances.First to offer a natural, large-screen experience when unfurled and a compact, portable experience when folded was the Galaxy Fold. Debuted in 2019. Samsung used never-before-seen hinge technology to make sure this capability felt natural and intuitive. The act of “folding and unfolding” evolved as a new category of mobile interaction.
In addition to feeling comfortable and simple to operate, the inward-folding hinge offered strong display protection. When folded, the phone would remain thin and flat and open with the same smoothness as a book. Its convenient size was largely due to its palm-sized dimensions. The era of smart foldables was launched by Samsung with the original Galaxy Fold, which attained a maximum folded thickness of just 17.1 millimetres.

Flex Mode Era: Hidden Hinge and Sweeper Technology.
When folded, the thickness is 13.8–16.8mm. Thickness at unfolded length: 6.0–6.9 mm Measuring 282 grammes.
Replacement for the breakthrough Galaxy Fold debuted in 2020. The Galaxy Z Fold2 redefined foldables with its sleek, modern appearance. The most noteworthy of its many cutting-edge innovations was the Hideaway Hinge, which supported sturdy folding and unfolding while smoothly connecting the smartphone’s body. The Hideaway Hinge allowed users to quickly capture selfies and make video calls in Flex Mode by mounting the Galaxy Z Fold2 at different angles.
The inventive dual CAM mechanism was made possible by the Hideaway Hinge’s more than sixty components. Flex Mode and the ability to keep the device open or closed were made possible by the flat area between two ridge-shaped portions, or CAM. Wider angles might be consistently supported by the hinge by adding more CAM structures and springs. The Galaxy Z Fold2’s Hideaway Hinge was placed in the ideal spot to allow for an even smaller design and a maximum folded thickness of just 16.8 millimetres.
The device’s front and hinge housing would inevitably separate since the hinge was always folded when the device was opened or closed. Samsung needed to create a long-lasting, elastic component without gaining extra bulk in order to successfully reduce this gap.
Samsung developed Sweeper Technology, which uses finely chopped optical fibres to solve this problem and was inspired by a hoover cleaning brush. Sweeper Technology made using a foldable phone more seamless by shielding the display from outside dust and particles that may otherwise enter via the gap.

The fact that smartphones nowadays are waterproof is a given. But with foldables, the hinge that opened and closed the screen was always open to the weather. The gadget might malfunction right away if liquids like drinks or even rainwater leaked inside.
One of the main issues with earlier foldable devices was that they were not water resistant, something that the Galaxy Z Fold3 solved. The hinge and the outside of the display are the two places where Samsung’s waterproofing technology was used. While the metal components of the hinge were protected from corrosion and coated with an enduring lubricant, the display’s outside was sealed off from dust and moisture by a rubber band.
Liquid could not enter the device because a silicone-based cured-in-place gasket (CIPG) sealed the terminal between the two mainboards that bordered the hinge. Furthermore, fragile components were shielded using flexible printed circuit board (FPCB) wires.
Galaxy Z Fold4
Galaxy Z Fold4 2022
The Galaxy Z Fold4 debuted in 2022 lighter and slimmer. Twenty-plus grammes lighter than the Galaxy Z Fold2, which weighs 282 grammes. This foldable was the thinnest in the series, folding to 15.8 millimetres. Samsung once again packed innovation into a foldable device, creating a tiny, light, and easy-to-grip design.
The Galaxy Z Fold4’s redesigned hinge, which is 21% lighter than its predecessor, was engineered to handle the Cover Screen’s bigger breadth and shorter length. The hinge mechanism of the Galaxy Z Fold4 is now linear rather than rotary, as opposed to the prior foldable in the series that used interlocking gears to ensure equal screen folding and unfolding.
By making this modification, the device’s robustness was increased and production was streamlined while also significantly reducing weight, thickness, and the number of parts. Samsung maintained the same degree of toughness as the previous design factor while creating the lightest and slimmest hinge to date with the Galaxy Z Fold4.

2023 The Galaxy Z Fold5 Flex Hinge: The Key to a Completely Foldable Smartphone

Galaxy Z Fold5 introduced 2023 foldable cellphones. Samsung’s Flex Hinge folds differently than Hideaway. The Flex Hinge, with its many features and enhanced flexibility, allowed the display to curl into the hinge like a droplet of water. It did this by using a twin rail system that allowed pieces to slide along it and four drive shafts. This hinge mechanism allowed the two screens to be folded equally, without any gaps or creases.
The lightest and thinnest Galaxy Z Fold series gadget to date is the product of this innovative folding mechanism. When folded, the Galaxy Z Fold5 has a maximum thickness of 13.4 millimetres, making it more than two millimetres thinner than its predecessor.
Additionally, the foldable is more compact, portable, and stable when folded because to its 253 grammes weight, which is 10 grammes less than its predecessor. From every angle, the phone’s elegant, sturdy design was pleasing to the eye.
Samsung uses exact engineering and rigorous production procedures to improve the Galaxy Z Fold series every year. Every aspect, from the outer design to the internal workings, is thoroughly considered. The Galaxy Z Fold series usefulness has been much increased by rethinking the hinges and device thickness key characteristics.
In order to make sure that more people can use its revolutionary foldables for even more convenient lives, Samsung will keep building on its legacy. Attend Galaxy Unpacked in Paris on July 10 to learn about Samsung’s newest features.
