Samsung Galaxy A51- Expert review

First of all, Samsung Galaxy A51 has been launched in India but only in one variant.

Samsung revamped the entire Galaxy A series last year to become more competitive in the mid-range segment of the market.

It is one of the most highly anticipated budget handsets of the 2020. It comes in affordable mid-range handset with a few features borrowed from the firm’s flagship range. 

The Galaxy A50 brought the optical fingerprint sensor, so the Galaxy A51 introduces the macro camera to Samsung’s smartphones, they just don’t stop innovating.





Above all its a mid-range smartphone with a big screen, big battery and plenty of photography features.

It’s slim, ergonomic and fabulous looking, has a remarkable display, and awesome software.

Our Main peeve points are the chipset, which stills falls short from a gaming perspective, also the not so fast charging.

It also offers quite premium and unique, even compared to the specs-heavy online exclusives.

Despite its not so great pricing, it will appeal to those looking for a polished experience.


Samsung Galaxy A51 is an attractive smartphone, with a large screen dominating the front and also an eye catching ‘Prism’ design on the rear.

Galaxy A51 got a pack of total of four cameras on its back.

While the screen is big at 6.5 inches, Samsung has kept the bezels super slim that is 7.9mm profile and a circular punch hole , which keeps the size of the handset down. There is also a 3.5mm headphone jack, USB Type-C port and speaker are all positioned at the bottom.

There is a thing the Galaxy A51 is missing, however, is an IP rating, which means it’s not officially water or dust resistant.

This phone is available in 4 different color yet – black, white, pink and blue.

It has a 6.5-inch, and it also GOT Samsung’s smallest ever pin-hole camera in the screen.

There are only three physical button on body –they are placed on the right side of the frame, like they were on its predecessor. However, if you press and hold the power button when the phone is on, it will launch Bixby.

Also, there is no pre-installed protector on the display.

Overall, in terms of the aesthetics, the Galaxy A51 is a very solid mid-range offering.


Above all it got Super AMOLED display is bright and colorful, with a good level of detail.

It uses an Infinity-O panel on the smartphone with an aspect ratio of 20:9.

Galaxy A51 has a sharp and agreeable full HD panel, we can choose to opt between ‘Natural’ or ‘Vivid’ color profile and also fine-tune the white point.

With OneUI 2.0 also has an awesome dark mode and an awesome display, even more Outdoor visibility, under direct sunlight, is fine as well.

It pumps out exceptional OLED displays without breaking a sweat, it is not a flagship-quality panel but you’d be hard-pressed to find a competing device with other devices which almost better.

There is also an Full HD+ (1080 x 2400), Super AMOLED display is bright and colorful, with a good level of detail and it also boasts Samsung’s smallest ever pin-hole camera in the screen.


The Galaxy A51 gives you such a good bang for the buck when it comes to the cameras.

Samsung also includes a 48-megapixel primary sensor; a 12-megapixel wide-angle camera; and a 5-megapixel depth sensor and that also includes a 12-megapixel camera in front.

The portrait mode may not be able to quite match the rear multi-cam setup and isn’t as proficient along the border between subject and background.

More about 48-megapixel pixel binned lens:

Above all, this lens is capable of clicking some really impressive shots during the day, with a good amount of detail and accurate colours.

This lens also helps elevate the low-light performance of the camera, it comes so handy when it comes to close-ups.

More about 12-megapixel wide-angle camera:

It has strong ultra-wide lens with an impressive 123-degree field of view.

Because of the decent amount of pixels on it, the images clicked using the lens also come out sharp with a good amount of detail.

More about 5-megapixel depth sensor.

This camera is counted in press materials.

Selfie Camera:

The images turn out okay in the end with nice colors and wide dynamic range. The detail is quite good as far as selfie cameras go too

Selfies generally weren’t very clear. Skin tones were smoothened a bit too much and shots ended up looking a little dull overall. Details were good in low light, but with a slight lack in sharpness.

Galaxy A51 records video up to 4K30, with all of its standalone cameras while it doesn’t do 1080p at 60fps.

With the 2160p videos it get a bit of 48Mbps, while 1080p makes do with 17Mbps, and those numbers are the same for both cams.

Stabilization isn’t available in 4K, but the A51 wills stabilize 1080p footage from both of its rear cameras, and the Super steady mode was a bit of a disappointment as it clocked at 25.5fps as opposed to a steady 30fps.


Navigating the interface was relatively quick, but it didn’t feel very fluid.

Even more there was a little lag in the system animations. Also, its performance looked decent with its Qualcomm Snapdragon 660 or 665 SoC would achieve.
