Samsung Galaxy Z Fold 5 waterdrop hinge enters rigorous testing

Samsung Galaxy Z Fold 5 is expected to feature a new waterdrop hinge, which reportedly entered the testing phase. Per Korean media, the company is going to start a final reliability test of a waterdrop-shaped hinge for an upcoming foldable phone releasing in the second half of the year.

As reported, the final hinge concept will be finalized after a month of testing. So far, Samsung foldables used a U-shaped hinge, which is now getting replaced with a new waterdrop-shaped hinge. As soon as the final concept is confirmed, parts production is expected to begin in May through KH Vatech.

TheElec sources claim that the South Korean tech giant is likely to begin a final reliability test on the waterdrop-shaped hinge concept to be applied to the Galaxy Z Fold 5. This kind of hinge supports both screens in close contact when a foldable phone is folded and lessens crease visibility.

In the recent past, Chinese vendors lowered the thickness of the hinge area to 11-14mm using the waterdrop-shaped hinge for foldable phones. Since the thickness of the phone reduced, there may be concerns with durability, hence, Samsung entered the hinge in rigorous testing.

For the Galaxy Z Fold 5, Samsung’s first goal is to reduce the thickness to 14mm or less since the thickness of Galaxy Z Fold 4’s hinge part is 15.8 mm. Ahead of finalizing the waterdrop hinge production, Samsung could carry out a folding test of 200,000 basic times and a limit of 300,000 times over the next month.

“When the product is folded 200,000 times, the durability of the foldable panel must be maintained within 15% of the initial strength to be evaluated as durable. It takes 4 to 5 days to conduct the 200,000 folding test.”

Post getting test approval, Samsung’s droplet-shaped hinge could begin assembling by KH Vatech. Furthermore, the device is expected to not feature any changes in specification and design, hence, Samsung may put the new hinge tech and lightweight design in highlight.
