Foldable smartphones are difficult to manufacture and expensive to buy. Even while the South Korean manufacturer is attempting to promote it as a durable phone, the fact, you need to treat it with a certain level of care.
The main screen on the Fold 4 measures 7.6 inches, making it comparable in size to tablets, and the secondary display measures 6.2 inches and is larger than the one found in Fold 3, making it easier to use. The Fold 4 is one of the greatest foldable phones now available. It is powered by the cutting-edge Qualcomm Snapdragon 8 Plus Gen 1 chip and comes equipped with cameras that are more powerful than their predecessors.
In general, it is an improvement over the Fold 3, but there is still a crease that can be seen running down the middle of the inner display, which is an issue that Samsung has not yet addressed. There is still a crease on the Fold 4, and even though it is less obvious now, it still has the potential to be a deal breaker for some customers.
Samsung has been working to improve the folding screen on its Galaxy Z Fold smartphone line-up. The company’s most recent model, the Galaxy Z Fold 4, has a more subtle crease than its predecessor, the Galaxy Z Fold 3, which was introduced by Samsung in 2021.
The next Galaxy Z Fold 5 may, thankfully, be Samsung’s opportunity to rectify this design flaw once and for all.
According to a rumor from a newspaper in South Korea named Naver, Samsung is planning to employ a novel waterdrop-shaped hinge on its next Fold 5 smartphone. This will enable the display of the device to fold fully flat without any gaps in between. This should mean that the foldable’s inner display will become more durable and will have no creases in it.
In order for you to truly understand this concept, the crease that you see on the display of Samsung’s foldable devices is caused by the design of their hinges. It would appear that the hinge is responsible for producing a sharp bend in the center, which exhibits itself as a visible stream on the display.
In addition, the article indicates that the new hinge in the shape of a waterdrop is known as a “dumbbell” type hinge on the inside. It is said that the redesigned hinge will make it easier to handle the smartphone and will boost the display’s longevity, both of which are additional benefits.
It is important to point out that, in contrast to Samsung, Chinese brands (including Xiaomi, Oppo, and others), have already removed the unattractive crease from the displays of their foldable smartphones. The most recent iteration of Oppo’s Find X2 series makes its debut with a display that is more streamlined and crease-free than Samsung’s best foldable. The Xiaomi Mix Fold 2 is hardly much different from its predecessor. It has a display that is likely the greatest in the business and is thinner than every folding smartphone that is currently available on the market.
It is interesting to note that Samsung may have already had this concept since the company patented the idea in 2016, at which time it was referred to as a “dumbbell” rather than a “waterdrop.” Even while the tech giant failed to explain why it had kept the design under wraps all this time, it is highly likely that the absence of an IPX8 waterproof grade is what prevented it from employing the concept from the very beginning.
According to Audio Reputation, the waterdrop hinge type is now included with the IPX8 waterproof rating, making it possible for the phone to be repeatedly submerged in water levels deeper than one meter.
