Galaxy Z Flip 4 survives extreme test of endurance with “sequels”


Samsung’s latest foldable representative in the “Flip” segment, the Galaxy Z Flip 4 barely passed YouTuber’s stress test Zack Nelsonfrom the channel JerryRigEverything. Despite having a robust construction in glass and metal, and even keeping the hinge in good condition even after facing dust, the launch did not come out unscathed when folded in the opposite direction, concluding the evaluation with “sequels”.

Starting with the construction, Zack found that the new foldable uses advanced materials on the sides, made of aluminum and accompanied by removable metal buttons, as well as on the back and the external screen, which uses Gorilla Glass Victus Plus glass — despite the pompous name, the plates continue to show scratches at hardness level 6 on the Mohs scale, with deeper marks at level 7.


Composed of a more resistant ultra-thin glass, the folding panel also follows the expected, as it still has a protective plastic layer. The area is pressure sensitive and has a low level of hardness, showing malfunctions at levels 2 and 3 of the Mohs scale. As a result, pressing the display harder using your fingernails can already result in unwanted marks on the film covering the panel.

In the lighter test, the plastic composition shows its own characteristics as it ends up melting over the flame, curiously protecting the AMOLED panel. Covered by glass, the external screen does not have the same fate: the pixels become whitish after a few seconds, a common result in OLED screens, presenting irreversible damage.


Like the more advanced Galaxy Z Fold 4, and by extension the predecessor Galaxy Z Flip 3, the Z Flip 4 manages to resist without problems, keeping the hinge in good working order, when exposed to a lot of dust. This reasonable level of resistance is a result of using small brushes in the openings, which prevent debris from causing damage to the movement mechanisms.

Although it performed well most of the time, the device encountered problems when bent in the opposite direction to the hinge, not only extending beyond the ideal, but also causing part of the display’s ultra-thin glass to break. Other than that, strange noises from broken components can be heard as the content creator keeps pushing the phone.

Impressively, the phone continues to operate normally, but with some sequels: in addition to the cracked glass, the device no longer stays closed completely, overcoming the force of attraction of the magnets that would keep it bent. Of course, the tests go far beyond what the device must pass in the hands of conventional users, serving only as a parameter to determine the evolution of the brand in resistance over the generations.

The Samsung Galaxy Z Flip 4 is now on sale in Brazil, with a suggested price starting at R$6,999.
