The main advantage of foldable smartphones is to save a large screen space, although the device itself has built-in dimensions and can be carried in the pocket easily.
When Samsung and Huawei launched this type of smartphone during 2019, the obvious flaws quickly emerged in the folding mechanism, which was a major weakness at the time; Due to the easy damage of hinges and moving parts in foldable smartphones.
Fourth Generation
The fourth generation of foldable smartphones are currently available in electronics markets, and the problems that emerged initially have already disappeared. Experts have confirmed through practical tests that foldable smartphones have become suitable for everyday life, although they still come at a high cost.
The test included Galaxy Z Flip 4 and Motorola Razr 2022 models, which fold horizontally and have a normal smartphone size when unlocked, as well as a Galaxy Z Fold 4 that opens like a book, and the smartphone screen turns into a tablet-like screen.
German experts explained that there was no concern about the detail's mechanical stability and stability in all the models tested. Unlike first-generation folding smartphones, the complex hinge mechanism is no longer breakable, it comes surrounded by a fixed metal frame, and the edge of the folding screen is clearly visible, but after a while it is not observed when the screen is effective.
Samsung asserted that its folding phones were not damaged by dust, soil and water spray; It has dust, dust and water resistance, according to IPX8 protection standards, which means it is water resistant up to 2 meters deep.
On the other side, the new Motorola Razr 2022 has resistance to dust, dust and water, according to only the IP52 protection category, which means it resists raindrops, but it must be preserved from falling into the water.
Motorola's foldable smartphone has some design advantages, which are not available in Samsung devices such as eliminating the gap in the screen, which takes the form of a wedge and arises due to folding, which appears in foldable smartphones produced by Huawei or Oppo as well.
Direct comparison
In a direct comparison between foldable smartphones, Motorola has a slightly larger screen than Samsung's Filp 4, which comes with a 1.9-inch touchscreen with a resolution of 260 × 512 pixels, while Motorola has a 2.7-inch display with a resolution of 800 × 573 pixels.
Small outdoor screens provide many practical functions in both devices; It shows calls, incoming messages, time statement and charging status, as well as access to the most important smartphone functions, such as starting phone calls or controlling smart home fittings without having to unlock the smartphone, but defects small external screens on which fingerprints appear clearly.
If the user wants to use smartphones to take pictures, it is better for him not to rely on foldable models; Because they provide suitable images in the case of good lighting but cannot be compared to the results of photography of luxury models in the event of reduced ambient lighting conditions.
The larger Samsung Fold 4 smartphone technical fittings package includes 3 lenses: the main camera, the ultra-wide-lens camera and the 3x telephoto camera, as well as the lens on the external screen and the selfie lens on the inside, the selfie camera operates with a very modest resolution of 4 megapixels, but the selfies look better using the front screen camera.
The main camera of Samsung's folding smartphone Fold 4 captures impressive images with resolution of up to 50 megapixels, due to the dynamic of the image, accuracy of clarity and richness of detail, and if the images are very colorful, the images can be later edited by photo editing software with the availability of 3x optical zoom.
Summary
In summary, Samsung and Motorola's foldable smartphones have eliminated the problems that initially arose, and even if they are not currently able to withstand the conditions of heavy outdoor use, they can be used as regular smartphones in the midst of everyday life.
The folding smartphones Filp 4 and Razr 2022 have a convenient practical format, but the user has to make some compromises regarding the quality of the built-in cameras.
Of course, Samsung and Motorola's foldable smartphones are defective of the exorbitant cost, so these models do not appear on lists of mainly best-selling devices.
