When it comes to folding smartphones with flexible screens, one of the thoughts that comes to mind is the degree of resistence. The most critical aspects of the project continue to coincide with the screen and the hinge that must guarantee the opening and closing of the panel, but generation after generation Samsung has managed to perfect its folding at levels that make it look like a distant memory. the problems of youth of the very first version.

Is the recent Galaxy Fold 4 as tough as its predecessor too? The answer is once again JerryRigEverything (Zac Bowden) who has subjected the latest top range Samsung to inevitable resistance test. Extremely concise judgment: yes. The new Galaxy Z Fold defends itself very well as it did with the previous Z Fold 3.

The most encouraging aspect is once again the hinge which holds the two parts of the body together: it does not yield even when trying to open the flexible screen outwards and exerting high pressure. More generally, the smartphone overcomes almost any mistreatment with agility, even if the flexible screen is reconfirmed as the most delicate element.

Dust and debris do not affect operation

Specifically, the internal screen shows the first grooves already at level 2 of the Moh scale and reports irreversible damage when exposed to the flame. The outer screen, protected by gorilla glass victus plus, has visible scratches at level 6 on the Mohs scale and lasts longer than the internal display before showing indelible signs of damage caused by exposure to the flame. Also noteworthy is the fingerprint sensor integrated in the power button that maintains the functions unchanged, even after being scratched with the cutter blade; finally, dust and debris do not seem to compromise the functioning of the device – even that of the internal screen (see min. 5.30 and following).

Samsung presents the new Galaxy Fold 4 as lighter and stronger than its predecessor. From the Zac test it is confirmed that at least on the resistance front it really seems able to equal (if not beat) its predecessor. The teardown test that did not end so well with the Fold 3 is still missing: the result could be similar, since the two smartphones share different construction solutions.
