With the Galaxy Z Fold2, Samsung is bringing the second generation of the foldable smartphone onto the market. The Korean manufacturer not only worked on the hinge, the displays have also been improved. We tested what innovations the new model brings and how the foldable performs in everyday life.

Galaxy Z Fold2: second generation foldable smartphone

Design and processing

The Samsung Galaxy Z Fold2 largely adopts the look of the first generation. While Samsung already showed another foldable format with the Galaxy Z Flip in the spring, the Galaxy Z Fold two remains with the vertical hinge. There is also a compact display on the outside as well as the larger (foldable) display on the inside, but more on that later.

Design and processing of the Galaxy Z Fold2

The frame of the smartphone is made of aluminum and has a brushed finish. In combination with Gorilla Glass on the front and back, the Galaxy Z Fold2 leaves a very high-quality impression. The processing is at a very high level and very successful down to the smallest detail. But how durable is the foldable smartphone?

While resistant glass is used on the two outer sides, Samsung uses the new "Ultra Thin Glass" on the inside. This in-house developed plastic-glass mixture should come very close to real glass and thus protect the flexible display. For further protection, a plastic protective film is applied ex works to both the outer and the inner display.

The most important component of the foldable, the hinge, has also been improved by Samsung. It consists of over 60 individual parts and should withstand around 200,000 folding processes over five years - that corresponds to around 100 folds per day. Furthermore, Samsung has learned from the feedback on the first Galaxy Fold and has integrated small brushes in addition to closing gaps. They are supposed to push small dust particles out of the hinge when it is opened, similar to a broom.

So far it seems to have worked very well and despite extensive everyday tests we could not hear any “crunching” in the hinge, but a long-term test must first show how well the small brushes actually work. Compared to its predecessor, the new hinge can be angled continuously from 75 to 115 degrees. Instead of the states “folded” and “opened”, the Samsung Galaxy Z Fold2 can now be used even more extensively.

The two displays - from smartphone to tablet

A compact AMOLED panel with a diagonal of 6.2 inches is used on the outside . The display has a resolution of 2,260 x 816 pixels and offers a refresh rate of 60 Hertz. Inside sits the large 7.6-inch AMOLED with 2,208 x 1,768 pixels and an increased refresh rate of 120 Hertz. Due to the adaptive refresh rate, the inner display can vary between 11 and 120 Hz, depending on what content the display is showing. When reading a text, the Galaxy Z Fold2 reduces the frequency, while playing, the maximum rate is enabled.

According to Samsung, the display brightness has also been improved and should now be a maximum of 900 nits. The brightness is always sufficient in everyday life and content can be easily recognized even in strong sunlight. The fold in the middle of the inner display is still pronounced and noticeable when using it, but it does not affect the use and is not particularly noticeable when looking at the screen horizontally.

When closed, the smartphone is still quite compact at just 159 x 68 mm, after opening it grows to around 159 x 128 mm and is more like a tablet. This is also shown by the weight of at least 282 grams. The Galaxy Z Fold2 is therefore not a flyweight, but in a certain way combines the functionality of smartphone and tablet in one device.

Performance, storage and battery life

While Samsung uses the in-house Exynos 990 chip for the Galaxy S20 and Note 20 series in Europe , the Qualcomm Snapdragon 865+ is used for the Galaxy Z Fold2. The cell phone processor is manufactured using the 7 nm process, has eight cores and clocks at up to 3.1 GHz. In terms of performance, the Galaxy Z Fold2 is at a very high level and can easily master graphics-intensive games in addition to everyday tasks.

The main memory offers around 12 gigabytes of LPDDR5, plus 256 gigabytes (UFS 3.1) of internal memory. An expansion via microSD card is not possible, but the Galaxy Z Fold2 is also dual-SIM capable via an integrated eSIM - i.e. 1x nano-SIM + 1x eSIM. Other features are Wi-Fi 6 (802.11ax), Bluetooth 5.0 as well as NFC and 5G . The foldable is unlocked primarily via a fingerprint sensor in the power button. The operating system is Android 10 with the Samsung One UI 2.5.

The battery capacity is 4,500 mAh and is implemented using two cell phone batteries in the two halves of the smartphone. The foldable smartphone lasted around 7 hours and 15 minutes in the PCMark8 battery test (inner display, adaptive frame rate, WLAN + GPS activated, 50% brightness). However, a benchmark does not reflect average everyday use, because the Galaxy Z Fold2 is not used continuously with the inner display. Depending on the usage behavior, the foldable lasts for at least one day and even has some remaining capacity the morning after.

Samsung uses a power adapter with up to 25 watts for charging, which means that the foldable smartphone can be fully charged in 65-70 minutes. Alternatively, wireless charging with a maximum of 15 watts is available, and reverse wireless charging for wireless charging of wearables is also on board.

The camera quality

The Galaxy Z Fold2 has a total of five camera sensors, two of which are intended for selfie recordings. The two front cameras, one outside and one inside, are based on a 10 megapixel sensor with f / 2.2 aperture and autofocus. The main camera on the back has three 12 megapixel sensors with different lenses. The main sensor has an f / 1.8 aperture and optical image stabilization, there is also an ultra wide angle camera with f / 2.2 aperture and a telephoto camera with f / 2.4 aperture, optical stabilization and a 2x optical zoom.

The image quality of the Galaxy Z Fold2 is at a high level and, thanks to the ultra-wide-angle lens and zoom camera, is quite versatile. Photos succeed with fast focusing, and dynamics, brightness and contrast are very well coordinated. Although there are now some smartphones that offer significantly more optical zoom, the Samsung foldable also focuses on other functions. Selfie recordings work quite well with both front cameras, alternatively the rear triple camera can also be used.

Conclusion - Samsung Galaxy Z Fold2

Samsung is launching the Galaxy Z Fold2 in Mystic Black and Mystic Bronze at an MSRP of 1,949 euros. This makes it a lot more expensive than other top smartphones, but Samsung has also invested heavily in the new display technology and the improved hinge. Currently, the foldable is still very different from the rest of the smartphone market, but foldable smartphones will certainly be a bit cheaper in the next few years.

In everyday life, the Galaxy Z Fold2 can be used very flexibly, especially due to the two displays. The outer screen is more than sufficient for quick activities such as replying to text messages or taking photos. However, if content is to be displayed larger, for example snapped photos or Google Maps, then the large, inner screen is a lot more practical. In addition, there is a successful multitasking for the use of several apps.
