The Samsung Galaxy Z Fold 8 Ultra failed a reverse bend test conducted by the YouTube channel JerryRigEverything, according to a video review of the device. During the evaluation, the foldable smartphone’s external structure and hinge remained intact, but a second flexing motion in the direction opposite to its normal opening caused the internal AMOLED display to permanently stop working and go black.
Galaxy Z Fold 8 Ultra Durability Test Results
The durability assessment followed standard evaluation steps, including scratch tests, heat exposure, and pressure applications, as reported by JerryRigEverything. The outer screen, protected by Corning Gorilla Glass Ceramic 3, performed like a conventional smartphone display against everyday hazards. However, the internal flexible panel proved more vulnerable, picking up scratches from sharp objects easily. When exposed to an open flame from a lighter, the internal flexible screen suffered permanent damage to its cells after nine seconds of direct contact, compared to ten seconds for the outer glass panel, according totugatech.com.pt. During the hinge evaluation, introduced dirt and debris caused friction noises, but the mechanical structure did not fail immediately.
Structural Integrity Versus Display Failure
While the internal display failed, the device’s main chassis and hinge mechanism did not snap in half, according to the test footage. Samsung builds the device using FlexTitanium, an Armor aluminum frame, and an Armor FlexHinge. Despite these reinforced materials, the extreme bending force caused the internal panel to fail by going completely black on the second reverse bend. Analysis cited by sources suggests the extreme force likely impacted the display’s flexible cable, internal sensors, or the panel structure itself rather than destroying the physical body of the phone.
Did You Know?
The Galaxy Z Fold 8 Ultra features an IP48 rating for water and dust resistance, meaning sand and particles can still infiltrate the hinge mechanism over time, as noted by notebookcheck.info.
Comparison with the Standard Galaxy Z Fold 8
The Ultra model’s failure contrasts with the performance of the standard Galaxy Z Fold 8. According to recent reviews, the baseline Galaxy Z Fold 8 survived the reverse bend test without losing screen functionality, despite significant physical deformation under pressure. Reviewers attribute this difference partly to thickness: the Galaxy Z Fold 8 Ultra measures just 4.1 mm when unfolded, leaving internal components with narrower margins to handle exceptional stress. Furthermore, a teardown of the Ultra variant revealed that Samsung omitted a dedicated cooling system around the processor, relying instead on thermal paste and positioning graphite sheets on the rear sections of the screens, as reported by tugatech.com.pt.
Frequently Asked Questions
Did the Galaxy Z Fold 8 Ultra break in half during the test?
No. According to the test results, the outer chassis, frame, and hinge remained completely intact. Only the internal flexible AMOLED display failed and went black.
How does the Ultra compare to the standard Z Fold 8 in durability?
The standard Galaxy Z Fold 8 survived the reverse bend test in previous evaluations, whereas the thinner Ultra model suffered a fatal internal screen failure on the second bend attempt.
What materials does Samsung use to protect the foldable screen?
Samsung utilizes FlexTitanium, an Armor aluminum frame, and an Armor FlexHinge alongside Corning Gorilla Glass Ceramic 3 on the cover screen.
