The Samsung Galaxy Z Fold 7, released in 2025, has undergone an extensive durability test by YouTuber Zack Nelson of JerryRigEverything, providing valuable insights into its foldable hinge and display resilience. The test, which involved repeatedly folding and unfolding the device, offers reassurance for potential buyers concerned about the longevity of foldable smartphones compared to traditional slab phones. Below is a detailed breakdown of the test results, their implications, and how they address durability concerns for the Galaxy Z Fold 7.
Test Results and Observations
- 6,000–10,000 Folds: The Galaxy Z Fold 7 experienced an unexpected reboot during this range, a minor issue that did not recur or impact functionality significantly. This could be attributed to software glitches rather than hardware failure, as the device continued to operate normally thereafter.
- 46,000 Folds: The hinge began producing a creaking sound, indicating potential stress or wear in the mechanical components. Despite the noise, the hinge remained fully functional, suggesting that the sound was not immediately detrimental to performance.
- 75,000 Folds: A liquid was observed seeping from the hinge, likely a lubricant used to ensure smooth folding. This is a concern, as it could indicate a design flaw or seal degradation, but it did not impair the hinge’s operation or the device’s overall functionality.
- 100,000 Folds: A slight crackling sound was noted, possibly due to further wear in the hinge mechanism or minor stress on the display. This did not affect the display’s performance, which continued to function perfectly.
- 105,000 Folds: The crease on the foldable display became significantly more noticeable. While this is a common issue in foldable phones due to repeated bending, it remained a cosmetic rather than functional problem, as the screen continued to work without issues.
- 175,000 Folds: The phone’s speaker failed, an unusual issue not directly tied to the folding mechanism. This could stem from internal component stress or an unrelated defect, but it did not halt the device’s core functionality.
- 200,000 Folds: The Galaxy Z Fold 7 successfully reached this milestone, with the hinge and display remaining operational despite the earlier issues. This endurance surpasses Samsung’s official claim of 200,000 folds, equivalent to approximately five years of use at 100 folds per day.
Implications for Durability
The test demonstrates that the Galaxy Z Fold 7 is highly durable, capable of withstanding at least 200,000 folds, which aligns with Samsung’s marketing claims. Assuming an average user opens and closes the device 100 times daily (including casual fidgeting), this translates to roughly 5.5 years of reliable use. Even with heavy use, the phone is unlikely to fail within a typical two- to three-year ownership cycle, addressing concerns about foldable phones’ longevity compared to traditional smartphones.
Key takeaways:
- Hinge Resilience: Despite creaking and liquid seepage, the hinge maintained functionality, indicating Samsung’s improvements in hinge design, likely incorporating advanced materials like carbon fiber and enhanced lubricants, as seen in previous models like the Z Fold 6.
- Display Durability: The foldable Ultra Thin Glass (UTG) display, protected by Gorilla Armor 2, showed only cosmetic wear (a more pronounced crease) without cracking or losing functionality, a significant improvement over earlier foldable generations.
- Speaker Failure: The speaker issue at 175,000 folds is an outlier, possibly unrelated to the folding mechanism. It warrants further investigation but does not undermine the device’s overall durability.
- Real-World Context: Most users are unlikely to reach 200,000 folds within a few years, and Samsung’s IP48 water and dust resistance rating (improved from IPX8) adds further protection against environmental wear.
Addressing Consumer Concerns
For those hesitant to buy the Galaxy Z Fold 7 due to durability concerns, this test provides strong reassurance. Compared to traditional phones, foldables face unique challenges due to their moving parts, but the Z Fold 7’s ability to endure 200,000 folds—equivalent to over 500,000 minutes of usage—demonstrates that it can rival the longevity of slab phones. Additional factors supporting its durability include:
- Build Quality: The Z Fold 7 features an aluminum frame, Gorilla Armor 2 on both the cover and inner displays, and a refined hinge mechanism, building on the Z Fold 6’s design praised for a 10% lighter hinge and 14% brighter display.
- Warranty and Support: Samsung offers a one-year warranty and optional Samsung Care+ plans, covering accidental damage, which mitigates risks for users concerned about hinge or display failures.
- Market Context: Competitors like the Google Pixel 9 Pro Fold and OnePlus Open have also improved foldable durability, but Samsung’s consistent testing at 200,000 folds sets an industry benchmark, as confirmed by third-party tests like those from MrMobile.
Tariff and Pricing Context
The Galaxy Z Fold 7, priced at $1,899 for the 256GB model (a $100 increase from the Z Fold 6), faces pricing pressures due to U.S. tariffs on Chinese-made goods, which could further elevate costs. Samsung’s partial shift to manufacturing in India and Vietnam may help offset these tariffs, but consumers should be aware of potential price hikes in 2025, especially given the broader trade tensions involving India (e.g., U.S.’s 50% tariff on Indian goods due to Russian oil purchases). Despite this, the Z Fold 7’s durability makes it a compelling investment for those seeking a premium foldable device.
Consumer Sentiment and Recommendations
X posts reflect positive sentiment toward the Z Fold 7’s durability, with users like @TechOdyssey praising its “tank-like” build and others noting its appeal for productivity and multitasking. However, some express concerns about the speaker failure and liquid seepage, urging Samsung to refine hinge seals. For potential buyers:
- Should You Buy?: If durability is a concern, the Z Fold 7’s ability to withstand 200,000 folds, combined with its powerful Snapdragon 8 Elite processor, 50MP triple-camera system, and 7.6-inch AMOLED display, makes it a reliable choice. Trade-in deals (e.g., up to $1,200 off at Samsung.com) and carrier discounts can offset the high cost.
- Precautions: Use a protective case, avoid excessive folding in dusty environments, and consider Samsung Care+ for added peace of mind.
- Alternatives: If the $1,899 price or foldable form factor feels risky, consider the Galaxy S25 Ultra ($1,299) or iPhone 16 Pro Max ($1,199), which offer similar performance without mechanical complexity.
The Galaxy Z Fold 7’s durability test alleviates concerns about foldable phone longevity, making it a strong contender for buyers seeking a premium, long-lasting device. Let me know if you’d like a comparison with other foldables or further details on its features!
