Overview of the Samsung Galaxy A21s smartphone with key features

The best gadget manufacturers attract users with functionality. The criteria for choosing smartphones are very diverse, but the buyer pays attention to the performance indicator, autonomy, equipment and how the device takes pictures. During the initial review, a person pays attention to the appearance of the device, as well as reviews from other buyers. Picking up the Samsung Galaxy A21s, it's impossible not to fall in love with it at first sight. Feelings will only intensify after turning on the device. The display is bright and attracts with its unusual appearance. The picture is clear. The user can find many useful functions in the menu. The fingerprint scanner is in the usual place, and the camera takes good pictures. Details below.

The history of the brand

The logo, which everyone knows without exception, was developed in 1993. A year later, the group's sales in the US alone reached $5 billion. The next year, the export figure reached $10 billion. In the second quarter of 1997, the company becomes a partner of the Olympic Games and the main sponsor of CDMA equipment in China (Shanghai). In the same year, the concern released a phone weighing 137 grams - the lightest at that time. In 1998, they began mass production of digital TVs and took a significant share of the world market. Brand focus is based on customers, who determine the future of the company. They strive to offer a product that would fully meet the needs of the modern user.

Close attention is paid to numerous social programs, sports, culture and environmental protection.

Samsung "A" series

Line "A" is considered the most extensive in Samsung. It should be noted that the series includes both cheap inexpensive models and moderately budget ones. It is also necessary to pay attention to the functional features of smartphones and their performance, which meets modern requirements. In addition to the unusual design, the phones are suitable for active games. A smart smartphone with a capacious battery can be used for long-term video viewing and Internet surfing. It is worth paying attention to the fact that the line is considered one of the best-selling. Three gadgets from this manufacturer were included in the rating of high-quality and popular models of last year, and all of them belong to the “A” line.

Regardless of the price, only budget materials are used.The case is made of plastic, and the glass covers the screen. It should be noted that smartphones such as the Galaxy A01 and A10 are produced only under the Samsung logo, while other Chinese concerns are engaged in their manufacture.

The Samsung Galaxy A21s has a good front camera and a comfortable diagonal, the gadget fits well in the hand. However, the pixel density leaves much to be desired (270 ppi). The prefix "S" indicates that the novelty was classified as high-speed ("s" - Speed). The higher the serial number of the smartphone, the more productive it will become, and the better characteristics it will have. I would also like to draw attention to the fact that the average price for the Samsung Galaxy A series line is rapidly decreasing as the next new product is released. Six months later, the cost of the gadget you like can be halved.

Characteristics

Positioning

At the beginning of 2019, Samsung adopted a fairly profitable strategy that allowed it to take a strong position in the ranking of high-quality and inexpensive smartphones. In the same year, they became leaders in sales of phones, largely due to the successful, productive and reliable "A" line. The product quality-price ratio is excellent. Samsung Galaxy A21s is able to break the record of its predecessors and become the most popular model in this price segment. More than attractive cost will force other manufacturers to reduce the prices of their products, which is one of the company's most popular marketing ploys.

When comparing the Samsung Galaxy A21s with A31 it is impossible to say with accuracy which model is better to buy. However, each smartphone has both its advantages and significant disadvantages. Both models are designed for young people who spend a lot of time with the phone in their hands. The interface has remained unchanged, convenient and understandable. The brightness of the screen is enough not to peer at it into the sun. Text visibility is good. The appearance of the device is very modern.The quad camera looks interesting, however, the colors of the body remained unchanged.

It is more profitable to buy a device with 6 GB of RAM. For games, the characteristics are enough, but they should be played at minimum settings. There is no ANT support, and this should be taken into account by athletes who use sports accessories with built-in sensors. As for the processor, the choice of processor fell on the Exynos 850, so the interface does not respond very quickly.

Despite the global crisis, the company has high hopes for the Samsung Galaxy A21s. However, this new product is unlikely to achieve such popularity, which the Samsung A51 has achieved.

Design and management

Modern devices are easy to confuse, as fashion trends dictate their own rules for the design of smartphones to multimillion-dollar conglomerates. The front part of most products is similar. The main differences can be found only on the back cover, where the main cameras are located. The Samsung Galaxy A21s has no geometric pattern. The back panel is made in a monotone color - a classic style. Four color options:

1. Black.
2. White.
3. Blue.
4. Red.

It is possible that additional solutions will be present in other markets. The body material is plastic, it did not receive protection from moisture and dust. Glass is only used on the screen, which has neat bezels. The weight of the device is 192 g, with dimensions of 163.6 x 75.3 x 8.9 mm. Ergonomics are observed and the device lies comfortably in the hand. The fingerprint sensor is located on the rear panel, and not built into the screen, as in many new products. According to most users, this is more familiar and more convenient. The response speed of the sensors is acceptable. Unlocking is carried out a second after touching.For the declared price segment, this figure is more than acceptable.

Face unlock is not provided by the manufacturer. For authorization in most applications, the use of a fingerprint scanner is still required. The paired volume button is located on the right side, in close proximity to the on/off button. On the opposite side is a slot for memory cards and SIM cards. It is not combined, so it should not cause difficulties in use. The main microphone is located on the bottom, near the headphone jack (3.5 mm standard). The sound of the speaker is mediocre, and the volume is not enough. Audibility is good, therefore, given the declared cost, complaints are out of place here.

The build quality is good. No creaks or backlashes were found. The model looks a little more expensive due to the monotonous plastic case. There is no protection against moisture, as well as against dust, which is similar to many other competitors. There is also no LED on the front camera.

Display and case

An impressive diagonal of 6.5 inches is difficult to call. The quality of the graphics corresponds to the declared characteristics of 720x1600 pixels, and the picture is not sharp enough. The side frames are quite thin and do not particularly catch the eye. The selfie camera is located in the upper left corner of the screen, which is considered an unusual and very original solution. The Super Amoled screen gives you rich hues and deep blacks. If necessary, the color rendition can be changed and set at your own discretion in the manual settings mode. Protection of the body and display is not provided, so it will not be superfluous to get a protective glass and a cover (closed type).

At first glance, you might think that the case is glass, but this is one of the features of the material used, which goes through several stages of grinding and is covered with a special layer. The brand has not forgotten about practicality, so the headset jack is conveniently located on the bottom edge. The front camera of 13 megapixels copes with the tasks.

Lots of cameras but no stabilization

The main camera consists of four modules, each of which performs its own functions. The main module is 48 megapixels and an aperture of f / 2.0. A Quad Bayer scheme is used for improved light sensitivity and improved color reproduction. In standard mode, the camera will shoot with a resolution of 12 megapixels. The second module is considered wide-angle, with a resolution of 8 megapixels. The 2 MP module is responsible for how the phone takes pictures at night. There is also an additional 2-megapixel lens.

The front has a 13 megapixel module, so the selfies will turn out to be of high quality. Even in low light conditions, the photos are juicy and bright. Detailing is not bad, provided that the stabilizer is missing. Color rendition is close to reality. Shadows look good.

The wide-angle lens noticeably loses sharpness. A similar defect can be detected when examining the edges of the image. Separate photos with the use of auxiliary modules do not turn out to be of high quality. In order to take a good photo at night, you will need to resort to automatic night mode settings, which only work on the main camera. Photos of signs and lanterns working at night are well detailed. Capable of shooting in HD at 1080p. and a frame rate of 30 fps. There is no image stabilization, so the video clarity will be low.

Performance

The model is equipped with a proprietary Exynos 850 chip. There is no information regarding the presence of a graphics processor. The RAM in the Samsung Galaxy A21s will be 3, 4 or 6 GB. The smartphone will have 32 or 64 GB of its memory, which is more than enough, provided that you can put an additional memory slot. Samsung's proprietary development is far from Snapdragon-730, but the phone will cope with everyday tasks. You won’t be able to play at high settings, but in most cases the toy will install quickly and you can start it without much effort. There can be frame drops in battles, quite obvious. It is not recommended to install tanks, the phone will get very hot.

autonomy

Responsible for this indicator is a 5000 mAh Li-Po battery (non-removable). The indicator cannot be classified as a record, but for a 6.5-inch screen it will be enough for a whole day of active use of the gadget. At maximum Super Amoled brightness, a lot of battery will not be used up, which will certainly appeal to those who like to read a book before going to bed. Watching videos and surfing the Internet for an hour of work will take no more than 10% of the charge, which is considered a good indicator. It should also be noted that there is a long cord to the 15 W charger and the possibility of fast charging. The rate of energy replenishment is about 25-30% in half an hour. The device does not support wireless charging.

Conclusion

The Samsung Galaxy A21s could be another hit from the big name brand. The cost of the model is $ 210, which allows it to be classified as a budget one. The 6.5 inch screen is easy to use. The smartphone fits comfortably in the hand, but the main camera protrudes slightly, so it is recommended to purchase a case for it.The power of the device is enough to perform everyday tasks. The case is made of plastic and painted in a single tone, without visible transitions and patterns. However, the phone does not look fragile, as it may seem at first. The lack of protection against dust and moisture had a positive impact on the cost of the product, which is intended for a wide range of users.
