Samsung Galaxy A51 Review – Samsung started 2020 by presenting two new Galaxy A series. Starting with Galaxy A51 and followed by Galaxy A71. Galaxy A51 is the successor of the Galaxy A50. In February 2019, Samsung simply “torn” the market by offering a gadget with a SuperAMOLED screen and an in-display fingerprint scanner, three cameras, NFC, a smart battery, and all this at the price of Xiaomi.
- Modern design
- Excellent Infinity-O AMOLED display
- Good photos with enough light
- Samsung Pay (NFC)
- Good battery life
- Plastic casing
- Mediocre chipset
Compared to its predecessor, the camera aspect with a quad camera and the design of the Infinity-O Display or punch hole are the main dish of the Galaxy A51. However, it is still reinforced with the same chipset. Are there any flaws, or are we again facing the best choice in the middle class?
Immediately, here is a complete review of the Samsung Galaxy A51.
Super AMOLED Infinity-O Display
There are only two changes compared to the Samsung Galaxy A50 display. Firstly, the size has slightly increased from 6.4 to 6.5 inches.
Secondly, Galaxy A51 carries a punch-hole design that Samsung calls Infinity O.
This design was first introduced in the Galaxy Note 10 series, but on this Galaxy A51, the size of the punch hole in the top center of the screen is much smaller and is used to place the front camera.
The Super AMOLED display is familiar to high-end smartphones. This display has excellent color reproduction, good brightness, and the Always On Display features are all available and implemented as in the best mid-range smartphone. The only drawback is the lack of HDR support.
Design | Galaxy A51 Review
The Super AMOLED panel stretches to 6.5 inches with Full HD + resolution (1080 × 2400 pixels) in an aspect ratio of 20: 9. This aspect ratio change does not make the A51 longer, the height is still exactly 158.5mm as the A50s. This can be achieved because Samsung has reduced the screen bezel on the bottom side of the smartphone.
The main design is still identical like other Galaxy A series smartphones. The design is simple and slim with a rainbow pattern and effect on the back, although the material used is still polycarbonate plastic and the face is coated with Corning Gorilla Glass 3 with a very high-quality oleophobic coating.
The back is a polycarbonate plastic that collects fingerprints and becomes a problem for everyday use. However, on the white version, this problem is not so noticeable.
Most importantly, the Korean manufacturer does not limit users in any way. There are modern USB- Type C port, the usual 3.5mm audio jack, and a separate slot for microSD. Even the NFC module is in place. And yes, the fingerprint scanner works very well. Unmatched, better than all other non-flagship models.
The buttons like volume and power buttons are placed on the right side of the smartphone. Meanwhile, on the left side there is a SIM card slot that can load two SIM cards and a micro SD card.
There is one speaker on the bottom side. It is average in both volume and quality.
Samsung Galaxy A51 Review : Quad camera
In the camera sector, there are striking changes, the rear camera design appears with a rectangular box frame. But more importantly, Samsung added an extra 5MP camera with a macro lens and a camera with a wide-angle lens increased from 8MP to 12MP.
In light enough environmental conditions, you can shoot in 48-megapixel resolution. Unfortunately, if shooting with this resolution HDR mode is not available, but the sharpness of the image increases.
The main camera is still the same, 48 MP (f / 2.0) Bayer Quad with a size of 0.8µm per pixel and by default it produces 12MP (1.6µm) photos. 48MP photo mode can be selected by changing the aspect ratio of the photo to 4: 3H.
The expanded dynamic range is active by default and works very well. Disabling it does not make sense, the algorithm works perfectly.
Unfortunately, when we tested the camera at night conditions, the results of the photo looked quite noisy.
Other Camera Improvement
Another improvement, the camera with an ultrawide lens was upgraded from the previous 8MP to 12MP (f / 2.2) and presented a 123-degree field of view. This wide-angle feature is available in photo and video modes, by clicking on the three tree icon directly above the shutter button.
However, Samsung went a little further. For example, he added the function of correcting distortion in images from wide-angle cameras. As a result, the edges of the image are not rounded, and the objects in the photo look better, with no barrel-shaped effect.
One more, 5MP (f / 2.2) as a depth sensor used in live focus photo mode to produce dramatic bokeh effects. The bokeh photos are pretty neat to use, especially in sufficient light conditions.
The intensity of the bokeh can be adjusted from level 1 to 7. Other modes available are panorama, food, night, super slow-mo, slow motion, hyperlapse, and Pro mode.
Unfortunately, in Pro mode we can only set ISOs from 100-800, white balance, and exposure compensation. There is no option to adjust the shutter speed and manual focus. Galaxy A51 also features an automatic scene optimizer and HDR.
The biggest improvement that occurred on the Samsung Galaxy A51 compared to its predecessor was the ability of the camera. Where Samsung adds an extra camera, 5MP (f / 2.4) with a 40mm macro lens. Most competitors put 2-megapixel camera modules as a macro sensor, and Samsung decided to improve the camera up to 5 megapixels. Of course, this has a positive effect.
The close-up shooting is available separately from the photo mode, ideally, the distance of the object is around 3-5 cm.
For selfies, the Galaxy A51 is equipped with a 32 MP front camera (f / 2.2). Complete with filter support, beauty mode, wide-angle mode, live focus, and AR emoji. The selfie camera shoots nicely, the reduced size did not affect the quality.
For video recording, the rear camera is capable of recording 4K UHD 30fps video and 1080p 30fps on the front camera. Samsung’s highlight feature is Super Steady, which is useful for reducing shake when recording video. However, this feature only works at 1080p resolution, 4K video is not supported.
Performance | Samsung Galaxy A51 Review
This smartphone runs on the Samsung Exynos 9611 processor, the same processor that is on the Galaxy A50s. This SoC contains an octa-core CPU consisting of a quad-core 2.3 GHz Cortex-A73 and a quad-core 1.7 GHz Cortex-A53. And the Mali-G72 MP3 GPU and 6GB RAM memory configuration with 128GB of storage.
With large memory and RAM, the Galaxy A51’s performance is strong enough to handle multitasking. But it will be a little lag if you intend to make it as a gaming machine, Galaxy A71 with Snapdragon 730 is more ideal for gaming.
Our experience, this device can be used well for playing social media everyday, or create content. Especially with the support of a 4000mAh battery that can be fully charged for a maximum of 2 hours.
To prove its performance, we tried the PUBG Mobile game. The result, graphics and gaming performance remains smooth because this smartphone is supported by an AI game booster.
When we tried it on the PUBG Mobile game, the image that was displayed showed high graphics. In addition, when used for playing does not show any problems.
The game launcher is embedded in the Galaxy A51 which collects installed games and gaming settings. Like the profile ‘focus on performance‘ to make sure the smartphone is releasing its full potential and you can record action in games up to 1080p resolution.
Samsung Galaxy A51 Review : Battery
A 4000 mAh battery for a smartphone, looks not bad. A 10-nanometer chipset and a well-optimized One UI system inspire hope even more. However, in reality, the device works for no more than a day.
But the smartphone supports 15W fast charging capability. The speeds are not record-breaking, but for an average device it’s OK. To fully charge the smartphone, it takes about 1 hour 50 minutes.
Galaxy A51 is equipped with some features that already existed in its predecessor. For example NFC, In-display fingerprint, and face unlock.
Like other Samsung smartphones, the Galaxy A51 is also supported by Samsung Pay.
Samsung Knox also accompanies this device which allows users to store various personal files in a secure folder that is secured by Knox.

Conclusion | Samsung Galaxy A51 Review

This phone is a bet Samsung in the early 2020s, which presents photography capabilities, performance, long-lasting batteries, and brand-new designs that are tempting in the price range of $ 275 only.
