Galaxy A51 is the new Samsung smartphone, which has received everything necessary to win the love of users. It has a colorful frameless screen, a powerful battery, a nice design and a reasonable price. After a long test, we’re ready to talk about its strengths and weaknesses, as well as show how the camera shoots.

Plastic handsome

Like its predecessor, the case of the new A51 is completely plastic. It is quickly covered with micro scratches. The glossy edging is especially hard on – it seems that it can be accidentally scratched even with a fingernail. It’s better not to risk it or wear a smartphone without a case.

The gadget has become more rectangular, now its design resembles the Galaxy Note line. Adds similarities to the neat round hole under the front camera. This made the appearance of the Samsung Galaxy A51 more premium – the novelty looks for all the money.

To unlock, use the fingerprint scanner built into the display. It cannot boast a high response speed and impressive accuracy. His work depends on many factors: the angle at which the finger lies, outdoor temperature, humidity, and so on. At home, in ideal conditions, you can get to the desktop the first time. But while driving along the street, especially in cold weather, it is much easier to enter a password than wasting time trying to unlock using a fingerprint method.

A screen that’s hard to tear away

Samsung puts the best Super AMOLED matrices in smartphones, and the Galaxy A51 is no exception. Its display boasts bright and contrasting colors, ideal black depth and maximum viewing angles.

The large 6.5-inch panel with Full HD + resolution is great for watching videos and other multimedia content. The screen is protected by glass with a good oleophobic coating. Despite the large diagonal, the gadget does not look massive due to thin frames and a round cutout for the front. In terms of size, the new product is slightly smaller than the A50 with a 6.4-inch display.

The only drawback of the matrix is the lack of DC Dimming. This function reduces flickering of AMOLED at low brightness values, without it, some users begin to get tired after prolonged interaction with a smartphone. It is time for Samsung to pay attention to this problem and begin to solve it.

I would like to quickly

The device is built on the basis of the Exynos 9611 proprietary chipset with a frequency of up to 2.3 GHz. Galaxy A51 comes with 4 or 6 GB of RAM and 64 or 128 GB of internal memory. There is a separate slot for a microSD card up to 512 GB.

The speed of work is not a strong point of the device. The novelty often hangs in the interface, especially when scrolling through lists and minimizing applications. The version with 4 GB of RAM hardly holds several open programs in memory and often reloads them when switching tasks.

However, people who are not spoiled by the top flagships are unlikely to complain about performance. It is enough to use social networks and instant messengers without special difficulties, as well as run games on medium graphics settings. And many will not pay attention to small lags – most likely, the old smartphone slowed down more.

Samsung has updated the interface: the Galaxy A51 uses OneUI 2.0 based on Android 10.0. The shell is beautiful and neat. There are many user-friendly settings and additional features. For example, you can make a clone of the messenger for the second SIM card, remove the application menu, configure the desktop grid, change the theme. New gestures appeared, as in pure Android – they became much more convenient.

Samsung Galaxy A51 is equipped with an NFC chip, so you can pay in stores using a smartphone. There is also an MST for payment on terminals that do not support contactless payments. Other wireless modules are dual-band Wi-Fi and Bluetooth 5.0.

Cameras in trend

Novelty received four cameras on the back of the case. The main “eye” has a resolution of 48 megapixels, there is also a 12 megapixel wide camera, a 5-megapixel auxiliary module that measures the depth of field in portrait shots, and a 5-megapixel macro lens.

The quality of the shooting corresponds to the cost of the model. Galaxy A51 does not upset with bad shots or blurry images in any conditions, including in the dark, but there are not enough stars from the sky. Automation, for some reason, greatly brightens the frame, making it too bright. This can come in handy in cloudy weather, but even in the sun, distorted color reproduction is obtained. It is possible that later this will be fixed with updates, but for now you can evaluate the quality of photos in the gallery below.

The canals of Amsterdam turned out to be bright and colorful. You can visit at low detail: the bush on the right side and the trees in the background merge into a single mess
Plain street in Bruges. Automation has highlighted buildings too much; in real life they are much darker
Antwerp Station is one of the three most beautiful in the world. Galaxy A51 was able to capture this with dignity
Church of St. Bavon in Haarlem. Soft again overdone with the brightness and color rendering of the building
The same spot on the ultra-wide-angle module. Detail fell sharply, the image is blurry at the edges
Another example of shirik work. The quality is also low.
An example of shooting with the main camera in sunny weather on the beach in The Hague. There is no problem with color rendering and brightness
Close-up macro delivers good close-up shots.
The smartphone has a separate night mode. He takes a long shot, and the result is noticeably inferior to what modern flagships give out
Well-lit buildings are much better at night. Automation coped poorly with the light from the flashlight, the rest was a decent shot
Another example of shooting in the dark. Lots of digital noise, low detail

The smartphone shoots video in 4K without software stabilization, and with it – in 1080p at 30 fps. The shooting quality is decent: the image is smooth, the color rendering is pleasant.

For autonomy offset

The Samsung Galaxy A51 has a 4000 mAh battery with support for charging at 15 watts. A complete charger fills the battery in about 1 hour 50 minutes – not too fast.

The novelty has high autonomy. The model easily withstands the day of active use, in our case during this time a hundred photos were taken, several long videos were watched, many messages were sent on social networks. At the end of the day, about 30% of the charge remained.

A cyclic roller in standalone mode with an average display brightness the gadget shows for 19 hours. An hour of playing PUBG took up 15% of the charge.

The new Galaxy A51 got everything that an ordinary user could wish for: a beautiful design, a bright display with minimal frames, a large memory supply with a separate microSD slot. Belonging to the middle class produces low image quality and poor performance. However, almost all devices in this segment are far from photographic flags, and not everyone needs a powerful processor. Most likely, the smartphone will be as successful as its predecessor, the Galaxy A50.
