Samsung Galaxy Z Fold4 5G review: A smarter foldable phone

Samsung Galaxy Z Fold4 5G review: A smarter foldable phone | The Samsung Galaxy Z Fold4 5G offers a better multitasking experience and improved camera specs. Although in terms of design, Samsung’s main foldable phone is a little thinner. What about the presentation? Check out the full Samsung Galaxy Z Fold4 5G review.

There’s something different about the Samsung Galaxy Z Fold4 5G that makes me feel more sat-set-set and more productive when using this Samsung foldable phone.

Maybe it’s because of the new taskbar that makes multitasking easier, with the ability to run apps side by side and be able to drag or drop content between windows. This is great, give Samsung a thumbs up.

It’s also worth appreciating that its 7.6-inch home screen now feels more spacious with thinner bezels. The foldable phone also brings more streamlined apps to the big screen of the Samsung Galaxy Z Fold4 5G, which now also appears brighter.

In addition, the cover screen is also now wider because Samsung trimmed the mold on the left to make it thinner, although the screen dimensions of the Galaxy Z Fold4 are exactly the same as those of the Z Fold3. This makes it easier for me to use the cover screen.

Another improvement Samsung is making in the camera industry, by adding a 50MP main camera. Note that the sensor is also the same as the Galaxy S22 series uses.

Well, let’s try to review it more deeply, including knowing the performance of this high-end Samsung phone.

Specifications Samsung Galaxy Z Fold4 5G


The first thing I noticed on the Galaxy Z Fold4 was its front display, which now doesn’t look too cramped. Samsung offers a wider Z Fold4 aspect ratio compared to the previous generation, the Galaxy Z Fold3.

The increased look of the screen here makes the 6.2-inch cover panel easier to use with one hand. It’s a nice change because it will honestly make you more comfortable using the cover screen for things like checking notifications and responding to messages quickly.

Another positive aspect, the Galaxy Z Fold4 this time is not very large and heavy, although the cut is not much compared to the previous generation. This change is partly because Samsung makes its hinges thinner.

Judging by its dimensions, the Z Fold4 handles 155.1 x 130.1 x 6.3 mm when opened and 155.1 x 67.1 x 15.8 mm when folded or closed. While the Z Fold3 has dimensions of 158.2 x 128.1 x 6.4 mm (open) and 158.2 x 67.1 x 16.0 mm (closed). So Samsung’s latest version of the foldable phone is a little shorter and thinner.

Weight-wise, the Z Fold4 weighs 263 grams, while the Z Fold3 weighs 271 grams. Although there’s a slight cut in terms of dimensions and weight, I think the Fold4 Z still feels heavy in my pocket, and it’s still about twice the thickness of a regular smartphone when closed. Hopefully in future generations, Samsung can crop to be lighter and thinner again.

But what makes me happy is that one of the advantages of the previous series is that the cover and main screen templates have been saved, providing a wider viewing experience. Also, I like that the Bottom Screen Camera (UDC) on this phone is a little less visible, so it looks better integrated with the content that appears on the screen.

Talking about hinges on foldable phones is a delicate thing, also known as many questions. But this time Samsung is quite “question” with the hinge of the foldable screen because it is more resistant. Samsung uses a new hinge for the Z Fold4 with a narrower and thinner size of 6mm. This makes it easy to open and close the hinges.

Samsung claims that the fourth-generation Galaxy Z Fold family has been tested and certified to double down to 200,000 times. This equates to 100 times a day for five years. One of the keys to the durability of this Samsung foldable phone is in the screen that uses Ultra Thin Glass (UTG).

Samsung uses Aluminum Armor for body structure and hinge protection, while Gorilla Glass Victus+ protects the roof screen and rear body. In this way, the Z Fold4 body is more scratch resistant and stronger when dropped.

Again, this is all a Samsung claim, because it couldn’t have tested the strength of its screen hinge by opening the lid 200,000 times, to find out the truth of the claim, no.

The same resistance that Z Fold4 has when it comes to water. This foldable smartphone is already IPX8 certified. With this certification, the device is not only safe when pouring water, but also resistant to getting wet from rain, but also splashing in water.

Samsung says the Z Fold4 can stay in water at a depth of 1.5 meters for 30 minutes. If this statement is true, you can use it to create underwater photos. Again, I’m not too interested in trying it. So you don’t expect underwater photo samples.

Samsung offers a choice of various Galaxy z fold 4 colors, especially Beige, Phantom Black and Graygreen, as I use now. Yes, there is a more special burgundy color, which can only be achieved through renewal through


Samsung incorporates a high-spec display into the Galaxy Z Fold4. This foldable smartphone has a 7.6-inch AMOLED 2X Infinity Flex Display dynamic home screen. The display has a QXGA+LTPO resolution and an aspect ratio of 21.6:18, with a refresh rate of up to 120Hz.

As for the secondary screen when in folded position (cover screen) using the 6.2-inch Dynamic AMOLED 2X screen display. The resolution is HD+, with an adaptive refresh rate of up to 120Hz and an aspect ratio of 23.1:9.

For those who like to watch movies or play games, the screen quality of Z Fold4 I can be sure will make you happy. I’ve tested it when I’m trying to play with the best graphics, like the asphalt 9 game.

The large screen of the Z Fold4 allows me to enjoy the game because it looks very detailed and smooth, like when a little water hits my car. What a beauty!

Credit can be given to Samsung Display, the company that makes these display panels has done some interesting and innovative things to improve the brightness and color reproduction that users feel deeply. Good job, Samsung!

But there’s one thing that’s a bit of an exaggeration on screen. Yes, although Samsung has tried to remain better to be better than the initial generation, I’m sorry to have to say that the screen folds are still very noticeable on the Galaxy Z Fold4. Admittedly, the folds on that screen weren’t boring enough when I saw the movie as a whole.

Samsung itself has admitted that folds will always be present, but now the folds are less annoying for users compared to the initial generations. If you’ve been a Galaxy Z Fold user since the first generation, you can definitely feel a better upgrade.

Perhaps for Samsung, as long as there is no excessive protest, it means that users of the Z Fold4 5G are already quite comfortable with the presence of the screen fold. At the very least, Samsung makes up for it with a significant improvement in screen quality.

Not only does the big screen (when opened) get a better upgrade, but Samsung also provides cover screen improvements that show an adaptive refresh rate of up to 120Hz.

Interestingly, its small display still looks smoother when reduced to 48Hz, as the display is now 3mm wider, meaning it doesn’t feel “claustrophobic” when using this foldable phone with a closed screen.

I also had no trouble typing on the front screen panel (cover screen). This helps a lot, because sometimes I’m too lazy to open the lid of a big screen, just to reply to a received message or see a notification. The positive thing is that you can also save more on battery users.

Software and Android 12L

One of the biggest improvements presented to the Galaxy Z Fold4 is found in its software, and this is due to the new Android 12L operating system. FYI, this special version of Android is designed for big-screen devices, including foldable phones.

To make multitasking easier, there’s now a new taskbar that appears at the bottom of the Galaxy Z Fold4’s screen, automatically displaying its latest apps. Best of all, you can decide which favorite apps appear on the taskbar by simply rearranging the main line on the home screen.

As before, you can run up to three apps on your big screen at the same time. When trying it, I prefer to use only two apps, but it’s up to you to be able to use three apps if you want.

What I like the most, now I can simply take the app out of the taskbar to open the app and place it on the left or right side of the screen. Or you can scan with two fingers while opening an app if you want to place another app next to it.

In my opinion, one of the benefits of being able to run applications side by side is the ability to “drag and drop.” So, for example, I can drag a photo from the Gallery app to a message to send in Gmail. Additionally, Chrome now supports drag-and-drop functionality for things like photos and links.

Flexible mode has also been improved on the Galaxy Z Fold4, which places app content at the top and you can control it underneath as you fold the screen in half. Samsung is working with several developers to make better use of foldable screens like Google Meet, Microsoft Teams and Zoom.

Seeing all the new capabilities presented in this device, it’s no surprise that Samsung has claimed the Galaxy Z Fold4 as a smarter, multitasking foldable device. This time, Samsung’s statement deserves our approval.


I can say that the Galaxy Z Fold series is no longer behind the Galaxy S series regarding camera issues. The photographic capabilities of Samsung’s foldable phones have now been greatly improved. No wonder, fold4 basically uses the same camera system as the Galaxy S22 and Galaxy S22 Plus.

It starts with a 50MP main camera with a 23% brighter sensor, which can result in better photo quality. Then there’s also a 12MP ultra-wide camera and a 10MP telephoto lens with 3x optical zoom and 30x spatial zoom.

In addition to the telephoto camera, I also tried to take close-ups of some objects with the Galaxy Z Fold4 5G camera. As a result, I was very happy because I produced a sharp image with natural colors.

What’s interesting is that you can take hands-free photos by activating the Flex Mode function, or you can use the Rear Selfie Cam function to take selfies with the rear camera, using the cover screen as a preview camera or used as “glass” when taking selfies.


The Galaxy Z Fold4 is powered by snapdragon 8+’s new Da Gen 8+ chipset combined with 12GB of RAM. There are three built-in storage media options, namely 256GB, 512GB, or if you still miss it, you can choose a 1TB storage capacity.

For two weeks, I used it for testing, so far the Galaxy Z Fold 4 has proven to be fast and responsive. But that doesn’t mean I don’t have problems, as I noticed that there are some minor problems.

For example, an application that stops responding when two applications are running in parallel. I experienced this by dragging and dropping photos from the Gallery app to Google Drive.

For gaming performance, this foldable smartphone is also very powerful. When you try to play popular games like PUBG Mobile, Call of Duty Mobile, and Mobile Legends at the highest graphical settings for 30 minutes to 1 hour, everything can be devoured without any problems.

Funny, I also played heavy games like Asphalt 9, PES 2021, and Geshin Impact. I really liked the turbo boost and doing 360-degree turns in the asphalt 9 game. Similarly, when used to play PES 21, everything runs smoothly without delay.

I played the game Geshin Impact for 1 hour on average with a frame rate of 60 FPS and, besides I found no problems, the game ran smoothly. You can also play around with the “right-aligned” or higher-level graphics settings, but it heats up quickly.

Powered by fast specs, what are the performance advantages of the Galaxy Z Fold4 5G in numbers? I tried to test it with three benchmarking apps, version 9 of AnTuTu Benchmark, Geekbench and 3DMark.

From the test results with the AnTuTu Banchmark app, this Samsung foldable phone scored 985,823 points. While benchmark testing on Geekbench, the Galaxy Z Fold4 scored 1,335 in single-core tests and 3,778 in multi-cores. This scoring record is higher than the Galaxy S22 Ultra, with a score of 1,240 for single-core and 3,392 for multi-core.

As for graphics, I used the 3DMark Wild Life Extreme app to measure GPU performance, and as a result, the Galaxy Z Fold4 recorded an average score of 2,207 points, with an average frame rate (FPS) of 13.20 FPS.

Last but not least, the Galaxy Z Fold4 transcodes 4K video at 1080p slightly faster than the Galaxy S22 Ultra using the Adobe Premiere Rush app (45 seconds vs 47 seconds). That’s just a comparison.

Battery life and charging

Honestly, one of the things that makes me doubt about the Galaxy Z Fold4 is its battery life. Samsung hasn’t provided an increase in battery capacity for the Fold4 Z, but to 4,400mAh, the same as the Galaxy Z Fold3.

My doubts arise because, referring to the results of previous evaluations of the galaxy Z Fold3, its autonomy is only capable of lasting 7 hours and 36 minutes with 18% battery remaining. My doubts grew due to the spec improvements in the Fold4 Z, which definitely took more power. But in reality, my guess missed the mark.

Of course, this is good news, as the Galaxy Z Fold4 was able to last longer in our tests despite inconsistent results. We note that in standard mode (60Hz) on average it can last 9 hours and 28 minutes.

But when adaptive mode is activated, the average drops to 8 hours and 19 minutes. In fact, the record at that time was still no better than smartphones in its class, but at least there was an improvement over the previous series.

All exposure to these numbers is the result of paper testing with a benchmarking application. Personally, I prefer to see the results of its direct use. So far, for 2 weeks I used the Galaxy Z Fold4, the battery is quite durable in normal use.

The battery is still quite durable to use throughout the day for various normal activities such as browsing, typing, opening and sending emails, conversations on messaging apps, social media, photos, and occasionally watching YouTube videos. For daily display in time around 11-12 hours. It’s still pretty durable, as is that battery.

What about the charging speed of this phone? Galaxy Z Fold4 supports 25W fast charging with a USB-C connector and wireless charging with 15W of power. The charging time is also relatively fast, reaching 50% in 30 minutes.

Therefore, the concerns of users, myself included, about the battery life of the Z Fold4 are unproven. In addition to the improvements provided by Samsung, the presence of the new Da Gen 1 chipset of snapdragon 8+ is very influential in energy efficiency.

When it was first introduced, Qualcomm said that one of the advantages of this new chipset is that it is very efficient in power consumption. In addition, Samsung’s display has also improved the efficiency of the foldable panel, which also helps to prolong battery life.

Oh yes, speaking of battery charging, plus a cable via the USB-C and wireless connector, Samsung’s main foldable phone also offers powerShare fast wireless charging for charging the Galaxy Buds Pro 2 or Galaxy Watch 5. You can use the back of your phone to charge.


The Samsung Galaxy Z Fold4 is a good evolution of Samsung’s previous three generations of foldable phones. At first glance, the appearance is still quite identical to that of Fold3, with some improvements given in terms of software, durability and camera.

Its multitasking ability has also been greatly improved. Samsung deserves credit (along with Google) for developing a software experience with features like a taskbar, better drag-and-drop support.

This time, the camera system is also very good, with some more streamlined apps, such as Flex mode, which allows you to take hands-free photos or use the Rear Selfie Cam feature for selfies.

The higher quality of the screen is also improved. Samsung Display has been able to create a display panel with excellent brightness and color reproduction. The foldable screen is also getting stronger with the use of Ultra Thin Glass (UTG) technology.

But even if the hinge is now thinner and the weight of this device is a little lighter, I would say the Galaxy Z Fold4 is a very thick and heavy phone. Hopefully in the next generation we can see slimmer and lighter foldable phones.

Another obstacle is price. Although it is said that “the price remains the same” as the previous version, but for the size of the Indonesian pocket, the minimum price of RP. 25 million is still very high. For those who have thick pockets, they can buy the higher 12GB/1TB variant for £31 million.

So, in my opinion, this best foldable phone from Samsung is actually the best for those who are willing to pay a high price. Perhaps those who plan to buy a Samsung tablet can divert their budget to buy the Galaxy Z Fold4 5G, because they already receive a smarter foldable tablet and a phone in one package.
