The appearance of the new flexible flagship, at first glance, has not changed much compared to last year. Of the most visible is a new form of the triple block of the main camera. But in reality, the changes don’t end there.

As in the case of Flip3, Samsung is trying to adjust the look of flagship devices to the overall design of this year’s devices, so the new Fold has common features reminiscent of smartphones of the S21 line. Of course, with a reservation on the uniqueness of the format of the model. The body around the main camera is made of frosted Gorilla Glass Victus. The same glass, but glossy, protects the external screen of the novelty. There, the manufacturer additionally applied a protective film.

At the edges, the device is protected by an armored aluminum frame, which, according to the developers, is 10% stronger than others from similar materials used in smartphones. The arrangement of buttons, connectors, and holes is close to the standard.

In the open form on the right edge of the smartphone, there is a volume rocker and an unlock button, in which a fingerprint scanner is built-in, and on the left, there is a slot for one nano-Sim without additional space to expand the memory of the device with a micro SD card.

On the left half at the top and bottom are the holes of the speakers, comparable in size to those on Samsung tablets. On the right bottom, there is a USB 3.2 Type-C connector for connecting to a PC and charging. In addition, video output and USB host function are provided thanks to supporting the Dex desktop mode.

When folded, the Fold3 is a fairly thick smartphone. If you put it in the pocket of jeans, it begins to seem that two devices are lying there at once. But when you take it out and open it, a thin tablet appears in your hands. The reliability of this feature is provided by the hinge, which in the folded state is hidden behind the thick left edge of the smartphone with a beautiful Engraving of Samsung in the middle. It is designed for 200 thousand cycles of folding and unfolding, according to laboratory tests from the manufacturer.

The hinge is quite rigid. It allows you to fix the screen at any available angle when opened and is equipped with seals that protect all gaps. At the same time, the cleaning mechanism using a brush-roller does not allow fine dirt to get into the body of the smartphone. Like the Flip3, the Z Fold3 received moisture protection according to the IPX8 standard. However, such protection will not save from particularly small particles, such as microscopic dust or sand.

Flexible displays in their structure are quite fragile so two more layers of protection are used for their safety. Thin glass is applied directly to the fragile AMOLED panel, and the user’s fingers are already in contact with the final layer in the form of a wear-resistant plastic film. It is she who is the main protection, so it is strictly forbidden to remove it to avoid damage to a very expensive part of the smartphone. Engineers were able to improve its protective properties by 80%, so problems like dents from nails should be a thing of the past.

When folded, the smartphone lies in the hand as if poured, and the buttons are located exactly under the fingers. The weight feels very good because we are talking about as much as 278 grams, and this is much more than most flagships on the market.

In the unfolded form, it is not very convenient to grasp the Z Fold3 with one hand from behind, you have to pull your fingers. In this mode, it is better, and safer, to use the device with two hands. Moreover, it will not be possible to open it alone either.

The main bendable display at first glance does not differ in characteristics from last year’s flexible flagship. It uses a Matrix Dynamic AMOLED 2X at 7.6 inches with a resolution of 1768 x 2208 pixels and an aspect ratio of 4: 3. Most popular applications are adapted to the screen with this aspect ratio, but there are exceptions, such as Instagram – this application is displayed in the middle. For such programs in the system settings, there is a function that allows you to automatically optimize the interface for the aspect ratio of the screen.

The matrix supports a refresh rate of up to 120 Hz and HDR10+. With the adaptive model of the refresh rate of the screen up to 120 Hz, smoothness of work is increased when navigating menus, as well as in games. On this display, it is very convenient to read the news on our website, as well as spend time on books and manga.

When watching movies, videos on YouTube, or when playing remotely on Xbox, there are black bars at the bottom and top, since most of the content is adapted to the 16:9 format, and nothing can be done about it. As with the curve on the screen, which is visible on a black background, as well as at indirect angles. When touched, you can feel the hollow for the entire length of the screen.

It is also worth noting that as part of the production of panels for the Z Fold3, developers are using a new technological process called Eco2OLED, the essence of which is to abandon the use of the traditional polarizing layer. This improved light permeability and reduced power consumption by a quarter at the same brightness level, and also opened up the possibility of achieving a higher maximum brightness. The brightness of the screen when installed manually at 100% is about 490 nits, and indirect sunlight can reach just over 920 nits in automatic mode.

The main difference between the bending display is the presence of a camera under the screen. To achieve a more decent quality of shooting, the manufacturer had to sacrifice pixel density in this place. Especially large pixels on the screen in this place are visible in bright scenes, and when the display is turned off or flooded with black, which, however, is the same for an OLED solution, then the lens under the screen is very clearly visible if you look at it at an indirect angle.

The external screen of the smartphone has a diagonal of 6.2 inches, which is slightly smaller than the second Fold, but since the body of the device has also become slightly more compact, this is forgivable. The resolution has also become slightly higher and is 832 x 2268 pixels, and the refresh rate, like the main one, is 120 Hz.

The aspect ratio is 25:9, and despite the non-standard format, it is very convenient to use the external screen for quick everyday tasks, and applications scale well to narrow proportions. Around the display, there are small frames, and on top of it is embedded the front camera, which the manufacturer decided not to hide in the screen.

The brightness of the screen is about 480 nits when manually installed at 100%, and in automatic mode, the maximum value can reach 1000 nits.

Since both displays have similar characteristics and settings, most of the options they have in common, so even the brightness slider is the same.

PWM is used to adjust the brightness, as with all phones with OLED panels. The function “Comfort for the eyes” will make the colors on the smartphone screen warmer and reduce the level of blue glow, and will do this adaptively depending on the time of day.

For lovers of bright colors, the screen works in saturated colors mode by default, but if you want, you can put it in natural color mode, which makes the picture more neutral. The “always-on screen” function is available only for the external screen and has a wide range for customization in standby mode.

Security is responsible for the ability to configure several options for locking the smartphone. As usual, these are both lock settings for password, pattern, and pin code, and with the help of a fingerprint scanner and a front camera, both on the external screen and the main one. There are no questions about the fingerprint sensor in the button, it works lightning-fast and is better than ultrasonic, which is popular to embed in the screen.

The front cameras unlock the device in most cases well, and it takes them about 1-2 seconds to do this. True, sometimes misfires occur, especially at night. Face unlock also does not like masks, so you have to tighten them below the chin so that the system can recognize the owner. So there is always a backup option in the form of a fingerprint lock, and you will be forced to put a password or pin code in any case.

The device works out of the box running the Android 11 operating system with the One UI 3 interface, which has been modified to interact with the curved screen. To do this, the operating system was equipped with flex mode, which is a semi-folded form in several applications that divides the screen into two identical areas. So, in the YouTube application, a video in a horizontal form is displayed on one half, and all the rest of the information, comments, and recommended videos come from the bottom, and you, for example, can comment on the video on the bottom half without interrupting the streaming viewing, and it is convenient to do this by placing the Z Fold3 on the table.

The Camera app displays the camera image in an upright position on the right side, as well as the camera interface, and the left one shows the latest shots that you can quickly view without having to go to the gallery.

In a semi-folded state and a horizontal orientation, Flex mode displays the image from the camera on the top half, and the latest shots and camera control divide the screen in half from the bottom. Moreover, the position of the image from the camera and the preview of the pictures can be reversed using a special button on the screen in the corner. In addition, the location of the phone on the table allows you to conveniently chat in instant messengers or make a video call.

Another feature is the support of the S Pen pen, which used to be the main feature of the Galaxy Note line and Galaxy Tab tablets, but this year it migrated to the top-end S21 and the culprit of this review. True, for working with Z Fold3, the usual S Pen is not suitable. You need either the S Pen Fold Edition or the S Pen Pro. You will have to buy them separately, and the branded case with a compartment for carrying the stylus also does not hurt.

Speakers at the top and bottom on the half with an external screen are responsible for the stereo sound of multimedia content. The role of the right and left speakers for each changes depending on their position in the horizontal format of use.


Specialists from AKG are traditionally responsible for setting up the speakers. The device supports Hi-Res Audio with a discrediting frequency of 384 kHz with a bit depth of 32 bits. The quality is at the level of the latest flagships, that is, for a tablet phone is very good. The volume of the speakers is at a high level, and it is more than enough. Speakers do a great job with pop, rock, classical instrumental music, or electronics with pronounced bass.

Support for Dolby Atmos technology for creating surround sound in movies, games, and listening to music has not gone away. In addition, the 9-band equalizer allows you to manually adjust the sound, and for those who do not like to steam, there are presets for popular genres of music. The sound adaptation function allows you to increase certain frequencies depending on the selected age of the user.

As in most modern flagships, the audio connector for 3.5 mm in the smartphone is absent. Wired headphones can only be connected via USB-C, meaning you’ll need either an adapter or the appropriate headphones. Fans of wireless headphones will be happy that the device supports HD-codecs LDAC and aptX HD.

As in the case of the Galaxy Z Flip3, the new Fold got all the camera sensors, except for the subscreen, from the previous generation.

The main camera consists of three modules and an LED flash. Wide-angle camera module Sony IMX555 with a resolution of 12 megapixels is located in the middle of the unit. The lens has an equivalent focal length of 26 mm with an aperture of f/1.8. It is equipped with optical image stabilization and autofocus Dual Pixel PDAF.

The top lens is an ultra-wide-angle sensor Samsung S5K3L6 with a resolution of 12 megapixels, without autofocus and stabilizer. The angle of coverage of the image is 123 degrees, and the aperture is f/2.2.

The last lens is a telephoto lens SK Hynix Hi-1337 with a resolution of 12 megapixels with an aperture of f/2.4 and a focal length of 52 mm. It is used for 2x optical zoom and 10x digital and is also equipped with an optical stabilizer and phase autofocus.

The embedded selfie camera on the external screen has traditionally a resolution of 10 megapixels, and it uses Sony’s wide-angle IMX374 sensor with f/2.2 aperture and no autofocus, but with electronic stabilization.

The last module is a built-in 4-megapixel sensor under the screen and with an aperture of f/1.8. It is not so much needed for selfies as for unlocking the screen on the face and video calls.

The quality of photos in the main wide-angle module is obtained at a good level. The pictures retain a good level of detail, but at the same time have a small level of noise. Colors are natural and have a good level of dynamic range.

When shooting at night in the appropriate mode, the camera takes a series of several pictures and then combines them into one. At the same time, the image processing system copes well with noise but also does not overdo it with sharpness.

Pictures on an ultra-wide-angle camera also have a pretty good quality but are still inferior in detail and dynamic range, and also suffer from a slight deformation of the image at the edges. At night, photos are darker and quite noisy.

The telephoto lens at optical 2-fold magnification demonstrates a level of detail comparable to the main wide-angle module, with a good dynamic range. At night, the pictures get a little noisier, the focus is sometimes lost, and it takes a little time for the sensor to focus again.

The front camera on the external screen in normal shooting mode shoots a little worse than the main module. Portrait shots are decent, but sometimes some curls of hair are cut off during processing.

The subscreen module takes very poor-quality pictures, and it is needed only for video calls and will cope with this task.

It is also worth noting that the highest quality selfies can be obtained when shooting on the main camera. To do this, just click on a special icon in the “Camera” application in the upper corner of the screen, when the smartphone is in a folded state, and then open it and point the main camera at itself.

The wide-angle module and the front camera on the external display allow you to shoot video in a maximum resolution of 4K at 60 frames per second. The ultra-wide-angle and telephoto cameras are limited to 30 frames at the same resolution. The subscreen module shoots in Full HD at 60 frames. Electronic stabilization copes quite well with shaking during brisk walking, but optical still cope better, but it is present only on two modules (wide-angle and telephoto lens) and limits the shooting mode to Full HD resolution at 30 frames.

The heart of the Galaxy Z Flip3 is manufactured on a 5-nm process technology 8-core Qualcomm Snapdragon 888 processor, which has 1 Core Kryo 680 Prime (Cortex-X1) running at a frequency of 2.84 GHz, 3 Cores Kryo 680 Gold (Cortex-A78) at 2.42 GHz, and 4 cores Kryo 680 Silver (Cortex-A55) at 1.8 GHz. It functions in conjunction with the graphics accelerator Adreno 660 and 12 GB of RAM LPDDR5. Internal memory in the tested device 256 GB standard UFS 3.1. There is no possibility of expanding the memory, and the version with 512 GB of memory will have to pay 10 thousand prices more.

In addition to one physical SIM card, the smartphone allows you to bind the second number using the support of e-SIM technology, which is increasingly distributed all over the world, including in… The smartphone supports all modern networks up to 5G, which has not yet become widespread in our country. In addition, it supports modern wireless standards such as Wi-Fi 6 and Bluetooth 5.1 and is equipped with a navigation system with support for A-GPS, Glonass, Beidou, and Galileo.

The internal components of the smartphone are powered by two non-removable lithium-ion batteries with a total capacity of 4400 mAh (2280 and 2120 mAh).

Galaxy Z Fold3 expectedly does not differ in great autonomy, since there are two screens with a refresh rate of 120 Hz and a fairly powerful filling. Under high load during games and tests in benchmarks, the battery was able to last about 4 hours. With active surfing on the Internet and using instant messengers, it lives about 10-12 hours, and when watching videos from the internal memory – about 14 hours. The model supports fast wired charging at 25 W and wireless charging at 10 W. By wire, we were able to charge the smartphone using a proprietary adapter for 15 W from 0 to 50% in 36 minutes, and completely – in 1 hour and 16 minutes. Not 120-watt charging from the famous Chinese brand, but quite a good result.

In the basic tests of AnTuTu and 3DMark, the phone was identified as Samsung SM-F711B. In AnTuTu, he scores 770154 points and ranks 11th among solutions on Android:

CPU 209547
GPU 268695
MEM 140464
UX 151448
As for CPU throttling, in the benchmark CPU Throttling Test with a standard 15-minute test, CPU performance fell to a maximum of 95%.

We will test this device in projects such as Genshin Impact, P.U.B.G. Mobile, Dead Trigger 2, and Asphalt 9. In general, no performance issues were noticed in the games. In the phone menu, the average temperature of the processor and battery was 28 degrees. In heavy games, after an hour of gameplay, these values already rise to a maximum of 46 and 36 degrees, respectively. The body of the smartphone heats up in the main camera area, which is why it became not very comfortable to play with.

On the territory of ., the official cost of the Galaxy Z Fold3 in the version of 12 + 256 GB is 159 990 price, and with a memory of 12 + 512 GB – 169 990 prices. The smartphone is available. in only two colors – black and green. In the West, it can also be bought in the silver color of the case.

We received a test sample of the device in black. Included with it was a proprietary USB-C cable. The same kit is waiting for all users, except for the standard paperclip for removing the tray for SIM cards and documentation.

The charging adapter, S Pen, and case are not included, so you will have to buy them separately. By the way, the last two were given to pre-ordered, and even with a certificate for preferential screen repair for a year under the Samsung Care + program.


As a result, we can say that the Samsung Galaxy Z Fold3 is a wonderful multifunctional flexible smartphone-tablet, which shows that the manufacturer has decided on the format of the folding flagship and confidently develops it. Especially pleased with the course of this year’s line to improve reliability, as we are told by the reinforced frame and protection according to the IPX8 standard.

The foldable smartphone now doesn’t seem like something too fragile, though Samsung still cautions against some of the features of its use when you first turn it on.

The sub-screen camera first appeared in this kind of product, but so far it looks foreign, at times the callus of the eyes is even greater than the fold in the middle of the display.

The Samsung Galaxy Z Fold3 is an option for fans of the Note lineup thanks to supporting the S Pen and a larger screen. True, the pen is only an option for which there was no place either in the phone case or even in the configuration.

The high cost will not allow the Galaxy Z Fold3 to become massive. It costs immediately 30 thousand prices less than its predecessor, but the price is still unbearable for most users. However, looking at the perseverance of Samsung, you can hope that shortly folding smartphones will become widespread and will no longer seem like curiosity.
