Samsung galaxy z fold 4 aims to be the best foldable screen smartphone

Samsung debuted the Galaxy Z Fold 3 5G in August of last year. Internal and exterior displays were included. It was also the first smartphone from the business to include an under-screen camera. The rest of its selling qualities include compatibility for the S Pen stylus and IP8X waterproofing. As a result, this device is unique in terms of the revolutionary technology it employs.

Aside from that, its hinge has a subversive hidden design. As a result, it can handle 200,000 openings and closings. The phone also has an adaptable split-screen mode that can be used from a variety of angles. In general, the Galaxy Z Fold 3 has been regarded as one of the best smartphones on the market.

It is, without a doubt, a gorgeous smartphone. But it’s a model from a year ago. As a result, Samsung fans (and not just them) are clamoring for a new model. Samsung, on the other hand, does not linger. In August of this year, the new Samsung Galaxy Z Fold 4 is expected to be released.


Samsung intends to minimize the number of parts used in smartphone hinges. At the moment, the Galaxy Z Fold 3 is made up of two pieces. Only one is used in the upcoming Galaxy Z Fold 4. The Galaxy Z Fold 4 will be lighter and thinner as a result of this modification. Furthermore, due to the reduced number of parts, production costs are predicted to be cheaper.

Samsung is betting big on a new generation of foldable smartphones, estimating around 3 million Galaxy Z Fold 4 devices will be produced this year, up from just 1 million Galaxy Z Fold 3 units last year.

The Galaxy Z Fold 4 may inherit the Galaxy S22’s camera, according to leaked rumors on Korean forums. The telephoto camera features a new 1/3.94-inch sensor with 10-megapixels and a 69mm focal length. This lens features a 3x optical zoom, which is a little more than the Galaxy Z Fold 3’s 2x zoom. If this is the case, long-distance shooting will be greatly improved.

At the same time, the Galaxy Z Fold 3’s under-screen camera is just 4 megapixels. As a result, many details in the photographs are lost. A 10-megapixel front camera is likely in the Galaxy Z Fold 4.

The Galaxy Z Fold 3 is presently available for purchase for USD 1050. 


It’s difficult not to agree that the Samsung Galaxy Z Fold 3 is an extremely feature-rich folding-screen phone. However, it still lacks an in-screen fingerprint identification sensor, for example. We realize that implementing this technology in Samsung’s folding screen handset is a technological challenge. We’re talking about the phone’s unusual plastic-glass hybrid display. According to a recent Samsung patent filing, the Galaxy Z Fold 4 folding screen phone will use a new in-screen fingerprint identification sensor.

Fellow reviews website LetsGoDigital stumbled into a Samsung patent on the website of the World Intellectual Property Organization (WIPO). It mentions a fingerprint sensor with two sides. It will be sandwiched between the cover screen and the main screen. Because the cover screen is an AMOLED panel, it should be able to authenticate fingerprints just like other smartphones.

The two sensors will connect to the mainboard through a PCB, according to the source (printed circuit board). It will be fascinating to see what tactics Samsung employs to get the fingerprint sensor on the secondary display to work.

The patent does not imply that Samsung will utilize it. However, on the other hand, may utilize a hybrid of ultrasonic and optical fingerprint sensors. The former may be used for the cover display, while the latter can be used for the main screen. It will be simple to calibrate the optical fingerprint sensor on the main screen, however, it may take several cycles to get it right.

Nevertheless, the Samsung Galaxy Z Fold 3 comes with a side fingerprint sensor, which performs quite well. In a strict sense, Samsung has no motive to switch to other optical/ultrasonic technologies. However, if the Korean manufacturer opts for this strategy, the Galaxy Z Fold 4 will stand out. It will also be the first folding-screen phone in the world to adopt this tech.


The Galaxy Z Fold 4 might have a camera from the Galaxy S22, according to leaked rumors. The foldable device would forego the Galaxy Z Fold 3’s 12 MP camera, which allowed a 2X optical magnification, in favor of a more capable sensor this year. The Galaxy S22’s 10 MP sensor with 3X optical zoom would be used in the upcoming 2022 model. As a result, while utilizing the smartphone’s zoom, the quality of the images might be greatly improved.

Furthermore, the Galaxy Z Fold 4 will have a higher-resolution selfie camera. As a refresher, the Galaxy Z Fold 3 had a camera built into its internal screen, but it was only 4 MP, which limited the amount of information that could be captured in images. The Galaxy Z Fold 4 might include a front-facing camera with a resolution of 10 megapixels, which would allow for improved photo rendering.

In addition to increasing the camera quality, Samsung might improve the smartphone’s overall design to make it more robust. Samsung Electronics plans to reduce the number of parts for the hinge of the smartphone. The Galaxy Z Fold 3 now has two components, while the Galaxy Z Fold 4 will just have one.

Lastly, the leaks season for the Galaxy Z Fold 4 and Z Flip 4 is still early. The gadgets are not scheduled to be released until August, with a release date somewhere towards the end of that month. The Galaxy Z Flip 3 was the first inexpensive flip phone last year. We secretly hope that the price of the Z Fold 4 continues to fall this year.
