Samsung Galaxy Z Fold 5: a new hinge that would not bend

Would Samsung finally meet the expectations of users of its folding smartphones? According to Korean site NaverSamsung could indeed adopt a hinge in the shape of a “teardrop” for its Galaxy Z Fold 5, allowing its screen to bend in a smoother and more discreet way.

This innovation would allow the smartphone to fold completely, with no visible gap between the two sides of the slab when closed. At the same time, it would make the smartphone easier to slip into a pocket, since it would gain in finesse.

Both the Galaxy Z Fold 4 and Galaxy Z Flip 4 currently use a “U”-shaped hinge that bends the screen at a steeper angle when the smartphone is closed. This results in a more pronounced beading and additional pressure on the screen. Despite Samsung’s improvements over the generations, the crease is still quite noticeable on current models.

Other manufacturers of folding models have already adopted teardrop hinges to avoid the problems associated with the visible crease. This is particularly the case with the Oppo Find N2, which has an extremely discreet crease when open, but also with the Motorola Razr 2022.

Further increasing durability

Corroborated by the leaker Ice Universe, this new hinge design dubbed “dumbbell” was patented by Samsung in 2016. However, the company had not used this technology until now. The Korean media therefore assumes that the manufacturer preferred to wait to be able to associate its hinge with an IPX8 certification, dedicated to the resistance of the smartphone to water.

This standard was introduced for the first time on Samsung’s 3rd generation folding smartphones in 2021. It allows the manufacturer to stand out from its competitors, such as Oppo or Motorola, which do not have this certification.

The new hinge would also improve the durability of the screen, which would better withstand multiple openings and closings. It remains to be seen whether Samsung will integrate this technology into the Galaxy Z Flip 5; specialists in the screen industry are also predicting improvements in this direction.

Samsung should not present its next folding smartphones until next August. The next step for the Korean firm is currently the Galaxy Unpacked event in February, during which the manufacturer will unveil its Galaxy S23.
