The main advantage of foldable smartphones is that they save a lot of screen space, although the device itself has compact dimensions and can be easily carried in a pocket.
When Samsung and Huawei launched this type of smartphone in 2019, obvious defects soon appeared in the folding mechanism, which was one of the main weaknesses at the time. Due to the ease of damage to hinges and moving parts in foldable smartphones.
The fourth generation
The fourth generation of foldable smartphones is currently available in the electronics market, and the problems that appeared at the beginning have already disappeared, as experts have confirmed through practical tests that foldable smartphones have become suitable for daily life, although they still come at a high cost.
The test included the “Samsung Galaxy Z Flip 4” and “Motorola Razr 2022” models, which are folded horizontally and have the size of a normal smartphone when opened, in addition to the “Samsung Galaxy Z Fold 4” device that opens like a book, and the smartphone screen turns into a tablet-like screen.
The German experts explained that there was no concern about the stability and mechanical stability of the hinge in all the models tested. Unlike first-generation foldable smartphones, the complex hinge mechanism is no longer breakable, but rather it comes surrounded by a fixed metal frame, and the edge of the screen fold is clearly visible, but after a while, it is not noticed when the screen is active.
Samsung confirmed that its foldable phones are not damaged by dust, dirt, and water splashes. It has dust, dirt, and water resistance, according to the “IPX8” protection standards, which means that it is water resistant to a depth of two meters.
On the other hand, the new “Motorola Razr 2022” has resistance to dust, dust, and water, according to the protection class “IP52” only, and this means that it resists raindrops, but it must be preserved from falling into the water.
The Motorola foldable smartphone has some design advantages that are not available in Samsung devices, such as eliminating the wedge-shaped screen gap created by folding, which appears in foldable smartphones produced by Huawei or Oppo Also.
In the direct comparison between foldable smartphones, the Motorola device has a slightly larger screen than the Samsung “Flip 4”, which comes with a 1.9-inch touch screen with a resolution of 260 x 512 pixels, while the Motorola device has a 2.7-inch screen with a resolution of 800 pixels. x 573 pixels.
The small external screens provide many practical functions in both devices. Where incoming calls and messages appear on it, indicating the time and charging status, in addition to the ability to access the most important functions of the smartphone, such as initiating phone calls or controlling smart home equipment without the need to open the smartphone, but the disadvantage of small external screens is the appearance of fingerprints on them clearly.
And if the user wants to use smartphones to take pictures, it is better for him not to rely on folding models. Because it provides decent images in good lighting conditions, but cannot be compared to the results of shooting luxury models in low ambient light conditions.
The package of technical equipment for the Samsung “Fold 4” smartphone, the largest, includes 3 lenses: the main camera, the camera with an ultra-wide lens, and the 3x telephoto camera, in addition to the lens on the external screen and the “selfie” lens (self-taken image) from the inside, and the selfie camera works with modest accuracy. It’s 4 megapixels, but selfies look better with the front-screen camera.
The main camera of the Samsung foldable smartphone, “Fold 4”, is distinguished by capturing wonderful pictures with a resolution of up to 50 megapixels, due to the dynamics of the image, the accuracy of the clarity, and the richness of the details. (zoom) 3x optical.
In sum, the foldable smartphones from Samsung and Motorola have eliminated the problems that appeared at the beginning, and even if they cannot currently withstand the conditions of heavy use in the open air, they can be used as ordinary smartphones in the midst of daily life.
The “Flip 4” and “Razr 2022” foldable smartphones have a comfortable, practical format, but the user has to make some compromises regarding the quality of the built-in cameras.
Of course, the disadvantage of foldable smartphones from Samsung and Motorola is the exorbitant cost, so these models do not appear on the lists of best-selling devices mainly.
