On August 10, Samsung launched the Galaxy Z Fold4 / Flip4 two folding screen phone. Immediately after August 11, Motorola and Xiaomi also launched Moto Razr 2022 and MIX Fold 2 folding screen phone respectively. Although they are folding screen phones, SLASH GEAR today reported that Samsung folding screen phone hinge technology is more backward.
The importance of the phone hinge is reportedly not only in the ability to allow the phone to fold, but also in the curvature, durability and reliability of the folding screen. So far, Samsung has been using a more traditional hinge solution that leaves a noticeable gap when the phone is folded, thus allowing the phone to use a flexible panel with less curvature. Samsung’s recently released Galaxy Z Fold4 / Flip4 uses this traditional scheme.
Xiaomi, Huawei and OPPO have adopted a new waterdrop hinge solution, which allows the screen bend area to sink into the phone’s body when folded, forming a waterdrop shape. Waterdrop hinge solution can make the phone folded gap is smaller, the current market consumers are also more satisfied with this.
But Samsung found in the research and development stage, that the use of a water drop hinge will let the phone give up IPX8 level of waterproof, and can only do life waterproof. Therefore, in order to retain the IPX8 level of waterproof, Samsung still uses the traditional hinge on the Galaxy Z Fold4 / Flip4.
The company’s main business is to provide a wide range of products and services to its customers, including the MIX Fold 2.
In addition, the Motorola Moto Razr 2022, which also has a water-drop hinge, is only water resistant to life, and does not support IPX8.
