Samsung Galaxy M21

amazon Samsung Galaxy M21 reviews

Basic design but comfortable grip

Galaxy M21 owns a design that is not too prominent compared to its senior devices. In return for the edges of the Galaxy A series are rounded quite a lot and evenly in the corners; this helps bring a better experience more comfortable grip.

The back is where the camera and capacitive fingerprint sensor are located. The camera cluster of the Galaxy M21 does not protrude too high compared to devices of the same price range, which can be considered an advantage in design when it limits the camera glass from being scratched.

The front of the Galaxy M21 is protected by a 2.5D curved tempered glass panel, with a screen size of 6.4 inches Infinity-U design instead of Infinity-O like the rest of the A-series devices.

Possessing a large capacity battery of up to 6000mAh, the Galaxy M21 is quite thick (8.9mm) and a bit heavy at 188gram.

Overall in terms of design, Galaxy M21 has a basic appearance, not fussy, not colorful, in return for a comfortable grip.

Large display screen, using Super AMOLED panels

Although the product is priced at $220, Samsung still equips this product with a Super AMOLED panel, reaching 420 nits brightness, Full HD + resolution. These parameters are enough to meet the user’s “seeing” needs, high image detail, wide viewing angle.

However, the screen of the Galaxy M21 tends to be slightly yellowish; when receiving the device, users can actively customize the screen color in the settings to minimize the color rendering problem.

Great battery life, the most attractive thing in Galaxy M21

Galaxy M21 has a battery capacity of up to 6000mAh, a huge number that is hard to find in devices of the same price range.

A large battery capacity will help Galaxy M21 get extremely good usage time. Quickly evaluate the battery life of the Galaxy M21 with two basic tasks of playing games and watching videos for 60 minutes, setting the sound and screen brightness at 50%. The results are as follows:

– Loss of 8% battery (Arena of valor Mobile)

– 5% battery drain (Watch Youtube videos)

Thus, if you play games (Arena of valor Mobile) until the Galaxy M21 runs out of battery, it will take about 12 hours. According to this calculation, users will have to watch Youtube videos for about 20 hours to drain the 6000mAh battery from the Galaxy M21.

Galaxy M21 can easily operate for about two days without charging with normal usage frequency.

The large battery capacity makes it longer to charge the Galaxy M21 than other models fully. Although equipped with 15W fast charging, it takes more than 2 hours for Galaxy M21 to get 100% battery (charge from 0%).

In the first 30 minutes, users will receive about 25% of the battery (charged from 0%), with a 6000mAh battery capacity; 25% of the battery is also just enough to continue using if you are in an emergency.

Versatile multi-lens camera, 20MP selfie camera

Going through the camera parameters of the Galaxy M21, the device has up to 3 rear cameras with the following specific parameters:

– 48MP, f/2.0, 26mm (wide),

– 8MP, f/2.2, 12mm (ultrawide),

– 5MP, f/2.2, (depth)

Although the lack of the macro lens has recently become a trademark of Samsung products, this lack does not affect the user’s photography experience.

Evaluation of the photo quality of the Galaxy M21, although it has a 48MP sensor, f/2.0 aperture, and also has “enthusiastic” support from the software system. Still, the main camera image quality is only at the medium level. Not too impressive.

Overall color is okay, but the details are not high. M21 owns UFS 2.1 memory for fast image saving, but the camera’s capture and focus operation is not too fast. This forces users to be “calm” in the processing phases to ensure the main focus image is accurate, with no vibration, no vibration blur.

The Galaxy M21 does not handle backlit images too; well, the details of the dark areas will be partially overcome but create a feeling of slight noise.

In low light conditions, for example, in a cafe in the afternoon and evening, the Galaxy M21 still ensures that the overall picture has just enough detail. Still, the image color will be “more convenient” for the user in return for the image water. With taking photos and posting on social networks like Facebook, Instagram, the photo quality of Galaxy M21 is enough to meet this need.

In terms of selfie capabilities, the Galaxy M21 has a camera system of up to 20MP, which many “women” will enjoy because this parameter level promises to bring quality selfie photos, especially after going through some color filter as well as skin-smoothing effect.

Indeed, the camera of the Galaxy M21 meets the selfie needs of users well; right from the default camera application, the manufacturer has applied “slightly” some skin beautifying effects. You need to turn on the camera of Galaxy M21 and take a selfie to have a satisfactory photo.

The selfie camera will have a certain degree of color cast depending on the lighting conditions where you shoot. Still, it can be overcome by applying some available color filters or actively balancing the colors with the default photo-editing application of the device, very convenient.

Performance is just right for the experience.

Galaxy M21 is equipped with Exynos 9611 processor; this chip has up to 8 cores, including four high-speed cores and four cores clocked at 1.7GHz, for basic tasks such as communication, reading files, or surfing the web. Facebook, Galaxy M21 is still extremely responsive. The RAM level of the machine is 4GB, 64GB internal memory, although not too large, but enough to store documents, photos, and personal data. If you feel that the capacity is insufficient, users can add an external memory card up to 512GB.

The gaming ability of the Galaxy M21 is average in the segment. You can still “train” well into light online games like Arena of valor at high settings; the fps level is stable at 60 but unstable; sometimes, the fps drop to 55, 56, or 57 depending on the battle scene.

For PUBG Mobile or shooting games (FPS) like Call of Duty, etc., users should set the graphics settings to a moderate level to ensure the most stable experience.

Talking more about the internal memory of the Galaxy M21, the device has UFS 2.1 memory, which is a worthwhile upgrade because it improves a lot in the user experience. Faster memory will help find or launch applications faster, reduce “nonsensical” waiting times and reduce the inhibitions commonly found in other $220 price range models.

To make it easy to imagine, getting UFS 2.1 on the Galaxy M21 is like adding an SSD to a computer that has only used HDD before.

Fingerprint on the back, not too convenient

Galaxy M21 does not use an in-screen fingerprint like many other devices on the market; it only has a capacitive fingerprint on the back. This type of fingerprint does not meet modern and technological criteria. The convenience is also reduced because you have to run your hand down the back to unlock it.

But, the fingerprint in the screen sometimes reads, and scan speed will be affected because the screen is semi-dirty, sweaty, the screen protector is too thick to scan the fingerprint; meanwhile, the capacitive fingerprint on the face. The back is always more accurate, the opening and closing operations are smooth and precise.

Conclusion:

It can be seen that the Galaxy M21 is an interesting $220 device from Samsung. Just looking at the hardware parameters of the device, it is clear that the Galaxy M21 does not focus on a certain factor, such as fighting games; this device has a series of experience features for all user needs.

The company pushes the high battery capacity to the highest possible level, 6000mAh, to help make the life longer, the experience more seamless.

Support for multiple camera lenses allows for versatile mobile photography in any situation. If you are expecting a “multi-function” phone, then the Galaxy M21 will be a choice that is hard to ignore.
