Samsung Galaxy Z Fold 8 Ultra fails durability test

The Samsung Galaxy Z Fold8 Ultra goes straight from durability test to teardown with a costly display damage.
This summer brought us four new foldables from Samsung and Google, one of which has already met its demise. Now, unfortunately, it’s Samsung’s turn. The best and most expensive Galaxy Z Fold 8 Ultra failed JerryRigEverything’s durability test for the first time. Find out exactly how in the video.

Just a few days ago YouTuber Zack Nelson highlighted just how robust Samsung’s significantly thinner foldables from recent years were in comparison to the Pixel 11 Pro Fold’s disastrous performance during the bend test. Now he’ll likely have to revise that assessment in hindsight. Following the actually quite good results of the more compact Galaxy Z Fold8 in his admittedly brutal bend test against the usual folding direction, the significantly larger and more expensive Galaxy Z Fold8 Ultra (available here on Amazon US) is now revealing the limitations of Samsung’s current 4.1 mm-thin foldables. We don’t want to spoil the test, the text will continue after the video.

Costly display damage after the bend test

Despite the ordeal, the current Samsung Ultra-Foldable doesn’t break as easily as Google’s fourth-generation foldable phone. However, the flexible, titanium-reinforced AMOLED display stays permanently black after the second bend test, which could lead to expensive repair costs if a heavyset uncle were to sit on the foldable while it’s unfolded on a couch, as the tester points out as a theoretical example. Sure, a scenario like that is rather unlikely in everyday life, but these tests do show that you still have to handle foldables more carefully than regular smartphones, especially when it comes to dirt. 

Even with the Google Pixel 11 Pro Fold, which is officially IP68 rated for dust and water resistance, sand could get into the hinge and cause problems over time. This is even more true for the Galaxy Z Fold8 Ultra, which is only certified up to IP48. It’s also hardly surprising that you should keep fingernails and other sharp objects away from the plastic layer above the display. At least, the cover display offers the standard Corning Gorilla Glass Ceramic 3 protection against scratches. The teardown reveals that the modular hinge parts are not interchangeable with those of the wider Galaxy Z Fold8, even though they look quite similar.
