### Durability Test: Sturdy Frame but Fragile Inner Screen
The outer display of the Galaxy Z Flip 7 performed reasonably well during the scratch test. It showed marks at level 6 with deeper grooves at level 7—standard for most modern smartphones. Impressively, it survived the burn test for over 20 seconds without permanent damage. However, the inner display fared much worse.
Due to its softer construction, the inner screen picked up marks at base level 2 and was vulnerable to scratches from fingernails. It also suffered two distinct burn marks with similar heat exposure levels. This softer layer is a known issue for foldable screens and will likely be a challenge even for Apple’s rumored foldable iPhone.
To address this concern, Samsung now offers a free replacement of the inner top protective layer—a welcome relief for new owners of foldable devices.
The frame of the Galaxy Z Flip 7 is made from strong aluminum, providing robust protection to its internal components. While it can resist bending or snapping, sharp objects like keys can leave permanent marks. The back features frosted Gorilla Glass Victus 2, which resists scratches and hides fingerprints for a cleaner look.
In addition to these tests, the YouTube channel JerryRigEverything performed a dust test on the hinge mechanism. This simulates real-world abuse to ensure the hinge can handle debris without failure. Although the hinge produced some cracking noises due to fine particles inside, it passed the bend test without structural damage and only minor noises under pressure.
Overall, the Galaxy Z Flip 7 emerges from the durability test in good condition. Even Apple featured it on its official support account by accident, highlighting its quality. The inner screen remains a work-in-progress for the entire industry, requiring significant advancements to become more robust and durable.
