Samsung Galaxy A21s smartphone review with key features

The best gadget manufacturers attract users with their 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. Taking Samsung Galaxy A21s in hand, it is 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 its usual place and the camera takes good pictures. Details below.

Brand history

The logo that everyone knows without exception was developed in 1993. A year later, the group's sales in the United States 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 started mass production of digital TVs and took a significant share of the global market. The focus of the brand is based precisely on the 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. You also need 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 prolonged 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 body 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.

Samsung Galaxy A21s has a good front-facing camera and a comfortable diagonal, the gadget fits well in the hand. However, the pixel density is poor (270 ppi). The prefix "S" indicates that the novelty was classified as a high-speed one ("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 your attention to the fact that the average price for the line of Samsung Galaxy "A" series is rapidly declining as the next new product is released. Six months later, the cost of the gadget you like may be cut by half.

Specifications

Positioning

In early 2019, Samsung adopted a rather profitable strategy that allowed it to take a solid position in the ranking of high-quality and inexpensive smartphones. In the same year, they became the leaders in phone sales, thanks in large part to the successful, efficient and reliable "A" line. The price-quality ratio of the products is excellent. Samsung Galaxy A21s is able to break the record of its predecessors and become the most popular model in this price segment. The more than attractive cost will force other manufacturers to lower the prices of their products, which is one of the company's most popular marketing moves.

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

It is more profitable to buy a device with 6 GB of RAM. For games, the characteristics are sufficient, but they should be passed on the minimum settings. There is no ANT support and should be considered by athletes who use sports accessories with built-in sensors. With regards to the processor, the choice of the 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, the popularity that Samsung A51 has achieved is unlikely to be achieved by this new product.

Design and management

It is easy to confuse modern devices, since fashion trends dictate their own rules for designing smartphones to multimillion conglomerates. The front 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 lacks a geometric pattern. The back panel is made in a monotone color - classic style. There are four color solutions:

1. The black.
2. White.
3. Blue.
4. Red.

Additional solutions may be available in other markets.The case material is plastic, it has not received protection from moisture and dust. Glass is only used on a screen that 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 is comfortable in the hand. The fingerprint sensor is on the back and not built into the screen like in many new products. According to the majority of users, this is more familiar and more convenient. The sensor response speed is acceptable. Unlocking is carried out a second after touching. For the stated price segment, this figure is more than acceptable.

Unlocking by face is not provided by the manufacturer. For authorization in most applications, you still need to use a fingerprint scanner. The paired volume button is located on the right side, in the immediate vicinity of the on / off key. On the opposite side there 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 at the bottom, near the headphone jack (standard 3.5 mm). The sound of the speaker is mediocre, and the volume is not enough. Audibility is good, therefore, given the declared value, 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 from moisture, as well as from dust, which is similar to many other competitors. There is also no LED on the front camera.

Display and housing

It is difficult to name an impressive 6.5-inch diagonal. The quality of the graphics corresponds to the declared characteristics at 720x1600 pixels, and the picture lacks sharpness. The side frames are quite thin and don't catch your eye. The selfie camera is located in the upper left corner of the screen, which is considered an unusual and very original solution. Super Amoled screen gives you the opportunity to enjoy rich colors 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 case 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 body 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 connector is conveniently located on the bottom edge. The 13 MP front camera copes with the tasks.

There are many cameras, but there is 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. The Quad Bayer scheme is used to improve light sensitivity and color rendering. In standard mode, the camera will shoot at 12 megapixels. The second module is considered wide-angle, with a resolution of 8 megapixels. A 2 megapixel module is responsible for how the phone takes pictures at night. There is also an optional 2MP lens.

The front has a 13 megapixel module, so selfies will be of high quality. Even in low light conditions, the photos are juicy and bright. The detail is good, provided the stabilizer is missing. Color reproduction is close to reality. Shadows are visible well.

The wide-angle lens loses its sharpness noticeably. A similar defect can be found when examining the edges of the image. Individual photos with the use of auxiliary modules are not of high quality. In order to take a good photo at night, you need to resort to automatic night mode settings, which only work on the main camera. The photographs of signage and lanterns operating in the night are well detailed. Shooting in HD at 1080p is possible. and a frame rate of 30 fps. There is no picture stabilization, so the video clarity will be low.

Performance

The model is equipped with a proprietary chip Exynos 850. There is no information on 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 install an additional memory slot. Samsung's proprietary development is far from Snapdragon-730, but the phone will cope with everyday tasks. You will not be able to play at high settings, but in most cases the toy will be installed quickly and you can start it without much effort. In battles, skipping frames can be observed, very obvious. It is not recommended to install tanks, the phone will get very hot.

Autonomy

The Li-Po battery (non-removable) 5000 mAh is responsible for this indicator. 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 brightness, Super Amoled does not use up a lot of battery, which will certainly appeal to those who like to read a book before bed. Watching video 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 the presence of a long cord for 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

Samsung Galaxy A21s could be another hit from the famous brand. The cost of the model is $ 210, which allows it to be classified as a budget. The 6.5-inch screen is easy to use. The smartphone fits comfortably in the hand, but the main camera sticks out slightly, so it is recommended to purchase a cover for it. The power of the device is sufficient for everyday tasks. The body is made of plastic and painted in a single tone, without visible transitions and patterns. However, the phone doesn't look as fragile as it might seem at first. The lack of protection against dust and moisture has a positive effect on the cost of the product, which is intended for a wide range of users.
