A South Korean YouTuber recently put the Samsung Galaxy Z Fold 7 through an extraordinary durability test, manually folding and unfolding the device 200,000 times to challenge its resilience. Samsungās latest book-style foldable, praised for its slim design and 8-inch inner screen, claims a hinge capable of withstanding 500,000 folds under ideal conditions. This real-world experiment, livestreamed over several days, offers a glimpse into how the device holds up under intense stress, revealing both its strengths and vulnerabilities. While the phone survived the ordeal, minor issues emerged, providing valuable insights for potential buyers.
Early Challenges in the Fold Test
The test, conducted by the YouTube channel Tech It, began showing issues as early as 6,000 to 10,000 folds, with the Galaxy Z Fold 7 experiencing a āforced reboot errorā that recurred approximately every 10,000 folds. By 46,000 folds, the hinge started producing creaking noises, though the phone remained fully functional. At 75,000 folds, an unexpected black liquid briefly leaked from the hinge, raising concerns about internal sealing, but it did not reappear. These early hiccups suggest that continuous folding, unlike typical daily use, puts significant strain on the deviceās components.
Mid-Test Struggles and Resilience
As the test progressed, the foldable showed signs of wear. By 105,021 folds, the screenās crease became more pronounced, a common issue in foldables but not debilitating. The hinge, while still operational, grew smoother but lost some of its original elasticity, affecting the āFree-stopā feature that allows the phone to stay open at various angles. At 175,000 folds, a significant setback occurred when both the top and bottom earpiece speakers failed. Despite these issues, the inner display remained robust, showing no dead pixels or loss of touch sensitivity, highlighting Samsungās advancements in foldable screen technology.
A Milestone Achievement
Completing 200,000 folds, equivalent to roughly five years of heavy daily use at 100 folds per day, the Galaxy Z Fold 7 emerged largely intact. The test, conducted manually to mimic real-world handling, underscores the deviceās durability despite not reaching Samsungās 500,000-fold claim. The absence of catastrophic failures, such as a shattered display or broken hinge, signals significant progress in foldable technology. However, the speaker failure and hinge wear suggest that secondary components may falter before the primary folding mechanism, a critical consideration for long-term users.
This grueling test, far exceeding typical usage, demonstrates that the Galaxy Z Fold 7 is a robust choice for foldable enthusiasts. While minor issues like reboots and speaker failure appeared, the core functionality remained intact, reinforcing Samsungās engineering strides. For those eyeing this premium device, the results offer reassurance that it can handle years of regular use, though real-world factors like dust or drops may pose additional challenges.
