Samsung a 20 pros and cons

Performance in games

samsung, pros, cons

The main problem of the novelty is the presence of Exynos in the “iron” part of the device. Affecting the area of ​​3D graphics, this device is, to put it mildly, a stupid product, because only the Mali-G71 MP2 video accelerator is responsible for the gaming performance. As a result, it turns out a weak processor by modern standards, because resource-intensive applications are given to it quite hard, games that run on it begin to slow down terribly not only at medium settings, but also at high settings. The gaming performance of this 2019 smartphone can be compared to the Snapdragon 625, which was introduced back in 2016, which is a rather sad fact. If you are a gamer, we advise you to buy a more expensive model with Qualcomm processors, then you will not have problems with a cool toy.


The presented model has a 13MP main camera with an f / 1.9 aperture and a 5MP rear secondary camera with an ultra wide-angle lens. The field of view is 120 degrees, this factor easily allows you to fit a large group of people in the frame or architectural buildings. The Galaxy M 20 is a confusing camera for shooting enthusiasts. In good lighting conditions it achieves excellent clarity and good picture quality in general. But you can’t do without problems, since there is a lack of white balance, photos often get an unnatural shade, with a feeling of overexposure.

It is worth to pay tribute to the presence of a wide-angle camera, since the photos are very interesting and unusual, however, it would not hurt to add a higher resolution. The limited dynamic range of the main camera is expanded by the sub camera. But when shooting bright areas, the device has difficulty. Shooting in the dark shows a disastrous result. There is a lot of noise in the photo, and when the picture approaches, graininess and blurring of detail appear.


The smartphone package includes:

  • Smartphone.
  • SIM eject tool.
  • 15W fast charging adapter.
  • USB-C cable.
  • User guide.
  • Warranty card.
  • Models are available in 2 types with the characteristics of 3/32 GB and 4/64 GB (RAM / internal memory).

The presented device comes in 2 shades: “ocean blue” and “black coal”.


The presented device is equipped with an IPS-screen, not AMOLED. This is explained by the cost of the device, because for 12 thousand AMOLEDs can hardly be found anywhere, even in the Chinese market. The display has a diagonal of 6.3 inches with a resolution of Full HD 2340×1080 pixels, aspect ratio. 19.5: 9, the usable area is 84%. Despite the fact that we have IPS, the picture quality is at a very high level, keeping up with more expensive models.

It is worth noting the brightness and clarity of the display, which even has a slightly overestimated color saturation, but it is rather an imitation of AMOLED. In addition, the screen has a very deep black tint and practically does not distort colors at different viewing angles. The screen of the Galaxy M20 is quite presentable, and certainly not worse than that of its competitors.


The appearance of the device does not have any supernatural solutions, but it should be noted that it is ambiguous. Clear benefits that are immediately apparent. bezel-less display with a waterdrop notch and a small indentation at the bottom. At first glance, it resembles the OnePlus 6T, it is due to this that the smartphone looks much more expensive than its value. The new Infinity-O display is a proprietary solution from Samsung. The back cover is made of plastic, but even such a fragile material looks quite expensive and aesthetically pleasing in the presented novelty.

The device is equipped with a Type-C connector, made in a very modern solution. There is a fast fingerprint scanner with a very convenient location, a 3.5 mm headphone jack. The loudspeaker (speaker) is located on the side, due to this, the sound will not be muffled if you hold the smartphone in your hands or put it on the table.

Photo quality

Considering the Galaxy A20. a mid-range device, you can’t expect the footage it shoots to be at the flagship level. It should be noted that the white balance is periodically lost, which sometimes gives the photos a warmer hue. In sunny weather, the narrow dynamic range may cause the footage to be overexposed. If you shoot in cloudy weather when the light is softer, your photos will be beautiful.

With the onset of the evening and at night, the quality of photographs decreases. HDR mode helps you take sharper pictures.

The wide-angle module demonstrates mediocre image quality. It has a 5 megapixel sensor. Small details such as leaves and flowers merge into a homogeneous mass.

Review on Samsung Galaxy A20

In pre-2019, Samsung will present its updated series of smartphones Galaxy A. Model success in this veche and attract attention to the consumer and win admirers. Galaxy 20 e budget smartphone in series.


In the Galaxy A20, the SoC is based on its own production. Exynos 7884. It has an 8-core CPU (from two Cortex-A72 cores, working with a frequency of up to 1.6 GHz, and also a six-core Cortex-A53, with a frequency of up to 1.35 GHz) and a Mali G71 video core MP2.

Tova is a new chipset, there is a lot of information for koito for practice. Assuming a fourth version on the Exynos 7885, but with a downgrade. According to its characteristics, it can be classified as a middle class chip on Samsung.

The configuration for memory is one. 3 GB of RAM and 32 GB of internal storage. The latter can be increased with the help of a microSD memory card up to 512 GB.

If the interface is dead, the standard accessories are: Wi-Fi 802.11 b / g / n, Bluetooth 5.0, IMA support for FM radio and NFC.

The year has just begun, but it is already clear that Samsung is radically changing its strategy in the smartphone market. It looks like the South Korean giant is finally developing and the Galaxy A20, A30, A50 are the first smartphones to adhere to the new philosophy. We have already tested the A30 (review) and A50 (review), and now it’s time for the A20. the most affordable of the three presented.

Samsung Galaxy A20 has received a new software version, as well as a new Exynos chipset. But is that enough? Can Samsung finally match its Chinese competitors (especially Xiaomi) in terms of cost and performance in the affordable segment? Let’s answer all of these (and more) questions in our in-depth Samsung Galaxy A20 review.

Samsung Galaxy A20 Unboxing: Box Contents

The Galaxy A20 package bundle is the most common, so let’s just briefly list everything that is included in it:

  • Smartphone
  • Fast charger (15W)
  • USB Type-C cable
  • SIM paper clip and documentation
  • Important: Samsung does not include earbuds or protective case for the Galaxy A20

Samsung Galaxy A20 review: design and build quality

The biggest design change for the new A-series is the waterdrop notch, or as Samsung calls it, the Infinity-V display. Why is this important in 2019? Well, because Samsung was the only major player to resist last year, but has now embraced this trend quite zealously and uses cutouts everywhere itself.

    The exterior of the Galaxy A20 is what matters. The cutout on the Galaxy A20 is accentuated by smooth curves and smooth face unlock animations. The bezels surrounding the display, as well as the chin at the bottom, are noticeably smaller than we usually see on affordable smartphones. At first glance, everything is very good, but do not rush to conclusions.

      The back panel of the Samsung Galaxy A20 has a controversial design. Glossy polycarbonate looks a little dull. And cheap. The oval fingerprint sensor gives you a more efficient scanning area, but it’s positioned too close to the top and personally, it took me some getting used to before my index finger instinctively landed in the right place.

      Overall, the Galaxy A20 looks solid and comfortable enough, especially for a smartphone with a powerful 4000mAh battery, but read more about that below.

      Samsung Galaxy A20 camera review

      Now let’s talk about cameras. At the back, the Galaxy A20 has a 13MP primary camera paired with a 5MP secondary wide-angle camera. On the front, you’ll find an 8MP selfie camera.

      The rear camera of the Samsung Galaxy A20 can accurately reproduce colors even in low light conditions. Of course, competitors have better characteristics, but let’s not guess, but look at the real test results.

      The main camera of the A20 is good for the money, but nothing more. We managed to get balanced shots in the right lighting, and the Galaxy A20 performed slightly better than the Zenfone Max Pro M2. But Xiaomi Redmi Note 6 still takes the first place.

      In low light, the Galaxy A20 can take pretty good pictures, but not always. We recommend taking a few photos with a margin, because the A20 has a large percentage of blurry shots.

      Selfie camera works fine in daylight, but fails indoors and in low light.

        Overall, the A20’s cameras are imperfect, but there are not many competitors in this price segment that perform better. If the camera is important for you, we recommend paying extra and taking the A30 / A50.

        Samsung Galaxy A20 review: battery, connectivity and audio

        The Samsung Galaxy A20 has a USB Type-C connector and supports fast charging. both are still rare in affordable models. But as Samsung officially warns, the availability of fast charging may vary depending on the market.

        The battery capacity of 4000 mAh with an average screen resolution and not the most powerful stuffing easily ensures trouble-free work on a single charge during the day. Simply put, the battery life of the A20 is very impressive.

        The Galaxy A20 has the usual set of connectivity options, but it lacks dual-band Wi-Fi. We did not encounter reception problems during the tests. The sound output through the mono speakers at the bottom is not bad. The sound through the headphones is excellent.

        Samsung Galaxy A20 review: screen

        Samsung uses Super AMOLED with medium HD resolution (720×1560) on the Galaxy A20, but we found nothing critical. Most of this resolution will be enough, moreover, it has a positive effect on the operating time and performance. The colors are bright and pleasant.

        The standard color calibration is pretty good, plus there is a white balance adjustment (the advantage of using AMOLED, Samsung smartphones with LCD screens do not). If you prefer warmer tones, you can also use a blue light filter (this is a special setting in the A20 interface).

        The Infinity-V display has some semblance of drama, with the clock and app icons to the left, and the system icons to the right of the camera padding (just like on OnePlus smartphones). There is room for 3-4 app icons in the status bar and you can click on them to see more. Samsung is not adding an option to hide the notch, but now that elements like this are well received, it shouldn’t be an issue.

        Pros and cons of devices on “Android

        Smartphones based on the Android operating system are currently the most popular. This is due to the ease of use of the platform and the simplicity of the interface. The following pros and cons of Android phones can be highlighted:

        • Prevalence. You can always find the right model, affordable and functional in terms of properties.
        • Updates. The lineup is changing very quickly, and new versions of the operating system may already work unstable on previous models.
        • Malfunctions. Phones on “Android” are most often observed “freezing” when working. The download speed and overall dynamics of the system functioning are at a rather low level, especially if we are not talking about flagship smartphones.

        Despite the existing negative aspects, smartphones based on the Android operating system are gaining more and more popularity among users.

        Advantages and Disadvantages of Shockproof Phone

        Advantages and disadvantages of a push-button telephone

        Some conservative people still use the most primitive communication devices. This is convenient if the phone is only needed for communication. Let’s list the main pros and cons of push-button phones.

        Samsung Galaxy Edge S6 / S6 Plus

        “The first swallow” in the camp of smartphones with a curved screen. This device at one time looked like a tidbit. At that time, there was a top-end processor, an incredible display, a decent amount of RAM and much more interesting. It was the first “Samsung” with a curved screen. The Korean phone model instantly gained popularity. Queues lined up behind her. In principle, and now this smartphone looks quite appetizing. It is more powerful than a good half of modern phones from the middle price segment. Of course, he can no longer keep up with the flagships, but he can still bypass the “middle peasants” in synthetic tests. And in terms of the quality of shooting with the main camera (and the front one), there are no competitors from the middle level for him to this day. Therefore, it was worth disassembling this device in such a review.
