We continue to get acquainted with the new line of budget smartphones from Samsung – Galaxy A, and today we have one of the younger models on the review, the A20.
In terms of design, the A20 doesn’t stand out among other models in the Galaxy A line – rounded edges, a shiny back cover with a color overflow, thin frames and a drop-like cut-out (here it has more “licked” contours than the older brother considered a month ago ” Galaxy A30 – this cutout is much closer in shape, for example, to that of the OnePlus 6T). The frame, although not integral with the back cover, is also made of plastic.
The diagonal of the screen is the same as the Samsung Galaxy A30 and A50 – 6.4 ″, with the same aspect ratio of 19.5: 9. The thickening of the frame below these three models is also about the same, respectively, the screen of the A20 occupies the same 85% of the front panel area. The smartphone is available in four colors – black, dark blue, red and coral (pink-orange), we have the second version in the editorial office. In reality, it has a rather complex shade – depending on the angle of view, the body shimmers from pure dark blue to deep purple. Unfortunately, the plastic case is quite easily scratched.
The fingerprint scanner is located at the back, and it is high enough, so that to get on it with your finger there are no special problems. On the top is a noise-canceling microphone, on the right side is a volume control and power button, on the left is a SIM card tray (you can install two nano-SIM cards plus there is a separate microSD card slot). Below you can find a microphone, multimedia speaker, USB Type-C connector and mini jack for connecting a wired headset
By today’s standards, the smartphone is of medium size (158.4 × 74.7 × 7.8 mm) and relatively light (169 g) – it fits well in the palm of the hand, the power button is immediately under the thumb. Naturally, it will not be possible to control it with one hand (as with almost all more or less modern models), but in general the ergonomics of the A20 are quite on the level.
The Samsung Galaxy A20 uses a Super AMOLED display, with a diagonal of 6.4 inches and a resolution of 720 × 1560 pixels (pixel density of ~ 268 PPI). This is noticeably less than on older models with FullHD +, and the user can see individual pixels on the screen without any problems, however, with normal use of a smartphone, this resolution is almost never seen.
The display is quite bright – however, traditionally for AMOLED technology, the maximum brightness depends on the displayed image. So, at 100% fill of the entire screen with pure white, the brightness when setting the slider to the extreme right position was 340 cd / m², at 50% – already 360, and when three-quarters of the screen was black, the brightness of the remaining white square rose to 400 cd / m². The minimum brightness was 5 cd / m², which is quite a lot compared to some other smartphones, but it is quite acceptable – in complete darkness the screen “at minimum” does not seem too bright.
The colors of the display are saturated and bright – if someone does not like the overly juicy “Amoledovskaya” picture, you can switch to “screen mode – basic” in the settings, in this case the color gamut narrows to about sRGB space, and the image becomes much more “calm” “And more similar to what can be seen on IPS-displays.
“Adaptive” mode shows maximum saturation and contrast, but the image quality suffers, plus it gets a coldish tint – so we would recommend lovers of juicy pictures to stop at “Cinema AMOLED” or “Photo AMOLED” (minimally different from each other – visually this is manifested in a slightly different elaboration of details in the shadows).
The traditional problem of AMOLED – PWM, is there, but it was not possible to subjectively feel it. “Pencil test” shows flicker only at low brightness; already when the slider is set to the mean value, the “strobe” cannot be disassembled.
In general, we liked the picture that shows the Samsung Galaxy A20 – a screen with this image would look quite appropriate in higher-level models.
Platform and performance
The smartphone has its own production SoC – Exynos 7884. It includes an eight-core CPU (two high-performance Cortex-A72 cores operating at up to 1.6 GHz and six more energy-efficient Cortex-A53, with frequencies up to 1.35 GHz) video core Mali G71 MP2. This is a new chipset, about which so far there is almost no information; AIDA64 identifies it as Exynos 7885 – perhaps this is its lowered version. According to its characteristics, it can be attributed to the “lower-middle” level of Samsung chips. The memory configuration is one – 3 GB of RAM and 32 GB of internal storage (can be expanded to 512 GB with a microSD memory card). For wireless interfaces, everything is pretty standard – Wi-Fi 802.11 b / g / n, Bluetooth 5.0, there is support for FM radio and, what pleases, NFC.
In the synthetic benchmarks, the Samsung Galaxy A20 scores on average 10-20% fewer points than the A30; In general, the system performance is enough for the interface to work smoothly and almost without lags, and the applications run quickly. You can periodically catch small delays, for example, when opening a list of applications in a folder, but they are not critical – you unconsciously expect much less smoothness from a budget smartphone.
Under load, the smartphone heats up poorly, including in synthetic benchmarks. In the test for trotting, the decrease in the CPU frequency began only a quarter of an hour after its launch.
Samsung Galaxy A20 is running Android 9.0, supplemented by proprietary shell One UI. We have already considered separately the new interface of Samsung smartphones earlier, so we will not dwell on it in detail – everyone can familiarize themselves with its work in our video review.
The smartphone is equipped with one multimedia speaker, the speaker is not used to create a stereo effect. Miracles can not be expected from him: not the most impressive volume and a little deaf sound, with more or less good high frequencies – a noticeable lack of medium and especially bass. In general, the music on the speaker is clearly not worth listening to, and, in principle, it is realistic to miss a call in a noisy environment. In headphones, the sound is quite sufficient for ordinary listening to music on the go, but music lovers will have a number of quality questions – for example, the bass is not very picky and sounds too loud, and the high ones are blunt.
The Samsung Galaxy A20 has a dual rear camera module: a main sensor with a resolution of 13 MP (aperture f / 1.9 and an equivalent focal length of 28 mm) and an additional wide-angle one – 5 MP, f / 2.2 and 12 mm. The maximum video resolution is 1080p @ 30 fps.
The proprietary camera application is quite simple: swiping the viewfinder up and down switches between the rear and front camera, left-right – between different modes (photo, video, panorama, dynamic focus and professional). With the first three everything is clear, dynamic focusing allows you to make portraits with blurring the background, and professionally there are manual adjustments of ISO, exposure compensation and white balance (and the latter can be fine-tuned in Kelvin on a scale from 2300K to 10000K in 100 degree steps). HDR control is hidden in the settings, there is no quick access to this mode from the main screen – so it will most likely have to be kept in the “on, activated when necessary” mode.
If we talk about the quality of the Galaxy A20 photo, then it is worth noting that the white balance occasionally misses, which is why the pictures may become warmer in color, the dynamic range is quite narrow, and in sunny weather the frames may be overexposed (apparently, to work out details in the shadows – but at the same time bright areas of the image are highlighted. It is noteworthy that in cloudy weather, when the light is softer and there is not much difference in illumination, the pictures look better. At dusk, and especially at night, the quality is greatly reduced – clarity and detail suffer, the images look “blurred”, the dynamic range is further narrowed, and the camera itself is noticeably slower at sharpness and periodically makes frames out of focus.
HDR mode helps to draw out contrasting frames, displaying information in both bright and dark areas of the image, but sometimes the shadows are too bright, which makes these images lose depth and saturation and become faded and flat.
The wide-angle module shows mediocre image quality – the 5-megapixel sensor delivers noticeably lower detail, which is why small details like branches or foliage of trees merge into a uniform “mess”, and the dynamic range is even smaller than that of the main sensor.
The quality of shots in the Samsung Galaxy A20 can be described as average, but one of the younger models in the budget range is unlikely to expect outstanding results.
The Samsung Galaxy A20 is equipped with a non-removable lithium-polymer battery with a capacity of 4000 mAh and fast charging (15 W) is supported. The smartphone demonstrates very good autonomy – in the PCMark battery test, with a screen brightness of 200 cd / m², it lasted 10 hours; With an average load, the smartphone “lives” for two days without any problems.
