It is undoubtedly one of the wildest and most painful companies of the moment. A South Korean youtuber is working to test the latest addition to the folding smartphones of Samsung. The question of the sustainability of this type of product whose interior slab is particularly contacted by the multiple daily openings/closures remains crucial. According to the manufacturer of the Galaxy Z Fold 7, the smartphone screen is capable of enduring 500,000 folds, at least 10 years of use, at a hundred openings per day. The measures, indicates Samsung Display, were entrusted to the Veritas office, and were therefore certified by an independent company.
The South Korean Tech-IT Youtuber has chosen to carry out a real-time test on its channel. Here he is who opens and closes by hand a Galaxy Z Fold 7, in front of his camera, risking tendonitis for science; Because it leads the operation in real time, and with a good rhythm. He managed, in less than 12 hours, to exceed the 195,000 opening cycles (at a time when we write these lines), while the Veritas office test machine took a total of 13 days to reach 500,000.
This express test, with a pressure exerted on the device which is not constant (but is “Similar to real uses” According to the author of the test), is not – yet – was right of the screen of the Z Fold 7. Which does not mean that the device has undergone any damage. He reported having dealt with an error in restarting around the 6000th folding, then suffered a “Craching noise” At the hinge around the 46,000th. Around the 75,000 folds, a “Unidentified liquid” passed the hinge, and finally the speaker broke down 100,000 openings later. The terminal remains functional, however, and we can expect it to be still when the tech-it test will receive its end.
