Samsung Galaxy A51 Review

Samsung is rapidly expanding its A-series lineup in 2020 with a few new models. In this lineup, the company added Galaxy A71 and Galaxy A51 smartphones at the beginning of the year. Galaxy A51 has been launched in India for Rs 23,999. To keep the series new and fresh, Samsung has introduced the Galaxy A51 by making some improvements to the existing Galaxy A50s.

According to Samsung, the Galaxy A51 smartphone is the first smartphone of this series to come with an Infinity-O display and a macro camera sport at Rs 23,999. Apart from these highlighted features, many of its specifications are similar to the existing Galaxy A50S, including AMOLED display, processor and design etc. Apart from the Redmi K20 Pro (Rs 24,999) and Redmi K20, there is no other smartphone competition in this price, which may prove to be an advantage for Samsung.

So will this new lower mid-range smartphone prove to be better than the current competition? let’s take a look.

Samsung Galaxy A51 design

The design of the Samsung Galaxy A51 is quite similar to the Galaxy A50S. Its body is made of polycarbonate and weighs just 172g. Along with this, the phone also seems quite thin. Its thickness is just 7.9 mm. The fingerprints on its shiny back are easily printed. However, these marks are not much visible on the prism black color variants present near Hamre. The finish of the back panel is a bit slippery, but thankfully Samsung offers a case cover in the box of this phone for free.

The biggest change in the Galaxy A51 compared to the Galaxy A50s is the Infinity-O display, which we are seeing for the first time on Galaxy A-series phones. Samsung has named the Whole-Punch display as Infiniti-O. Like this hole-punch Galaxy Note 10+, this phone is given in the middle of the upper part of the display. Samsung may not have changed the design of the body of the phone too much, but having a hole-punch display gives this phone a premium look, which we appreciate. The Galaxy A51 uses a full-HD + resolution Super AMOLED panel, which gives punchy colors and good sharpness. Due to the thin bezel all around, its display looks great from the front.


Buttons on the Galaxy A51 also fit well. It has a card tray on the right side, in which two nano-SIM cards and a microSD card can be fitted. The 3.5mm headphone socket, USB Type-C port and speaker grill are given at the bottom. The rear of the Galaxy A51 has four cameras setup. The good thing is that its camera bump is not very bulge.

In addition to the phone in the box of Samsung Galaxy A51, there is a 15 watt fast charger, a Type-C cable, a headset, a SIM tray eject pin and a cover.

Samsung Galaxy A51 specifications and software

In Samsung Galaxy A51, the company has given the Exynos 9611 processor included in the current Galaxy A50S, which in 2020 and at this price, makes the phone feel a little weak. The Galaxy A51 is launched with 6 GB RAM and 8 GB RAM options. There is 128 GB internal storage in both variants. Apart from this, the phone includes dual-band Wi-Fi 802.11 AC, Bluetooth 5, GPS, NFC and FM radio etc. All the common sensors are present in this phone. The Galaxy A51 also has WideWin L1 certification. This phone supports Samsung Pay, so you can also use it for contactless payment.

The Galaxy A51 has a One UI 2.0 based on Android 10. This new version is similar to the previous version of One UI, which we have used before. However, the company has made some changes to make it better for the user experience. Instead of sending in themes, it now allows the UI user to change the wallpaper directly from the dedicated menu.


Apart from this, now the ‘Device Care’ sub-menu has also been given a new look. Battery usage information can now be tracked for the last seven days instead of the last full charge. Now you can also change the lockscreen app icon. As before, this version still has some bloatware (unwanted apps) pre-installed, including third-party apps and some Samsung apps, but most of them can be removed easily. Samsung has also added some India-specific features to the Galaxy A51. In this, the user can now convert SMS into a visual card. Apart from this, multilingual predictive typing and smart crops are also included.

Samsung Galaxy A51 performance and battery life

The Galaxy A51 feels largely similar to the Galaxy A50 in day-to-day use. We liked its slimness and light form factor. Its interface is fast to navigate, but it does not give a smooth feel. Sometimes we have also seen lag in its system animations. Its benchmark performance also does not affect much by Qualcomm Snapdragon 660 or 665 chipset. Overall, according to the price of this phone, it is slightly less.

Biometric authentication works well, but is a bit slow. Its in-display fingerprint sensor takes a little time to authenticate fingerprint and unlock the phone, and some similar face unlock feature is also available.


The Galaxy A51 comes with Dolby Atmos support, but this feature only works when you use headphones. The audio quality of the earphones that comes with it gives an average feel. However, this phone offers better audio with some high-grade earphones available in the market. The output of the speaker below is not high, but enough for listening alone. One of the best parts of this phone is its display. The brightness of the display is quite good and colors look good in it. Because of this, there is a good experience in watching videos in the phone.

The Samsung Galaxy A51 has a battery of 4,000 mAh capacity. This battery lasted 14 hours and 55 minutes in our HD video loop test. On regular use, this phone ran smoothly throughout the day and with the end of the day, it had half a day of battery life. Fast charging support has been provided in this phone. Upon examining us, we found that the phone charger can charge it up to 67 percent in one hour. It takes more than two hours to fully charge. Although it is fast, but it is slightly slower than other phones in the segment. For example, the Redmi K20 Pro charges up to 80 percent in one hour.

Samsung Galaxy A51 cameras

Samsung has added an additional 5-megapixel macro sensor to the new Galaxy A51 phone, compared to the triple camera setup included in the Galaxy A50s. The other three cameras include a 48-megapixel main sensor, a 12-megapixel wide-angle camera, and a 5-megapixel depth sensor.

The camera app in One UI 2.0 has also been slightly improved compared to earlier. Most shooting modes are now stored together in the “MORE” menu. The good thing is that you can add them to the main viewfinder interface as per your mind.

Its main camera captures photos in 12-megapixel resolution by default, but you can also take pictures at full 48-megapixel resolution. This option is given in the Aspect Ratio setting. In good lighting conditions, the Galaxy A51 camera takes a good detail picture of the subject in the center of the frame, but the subjuncts in the edges usually look a bit blurry and soft.


In low light the main camera took pictures with good colors. Photos come with plenty of detail and noises (dots) are seen in them. It also has a dedicated night mode, but we did not see much difference between photos taken with this mode and photos taken in standard mode, because in low light the app’s scene optimizer can change the camera setting to low light Sets it up.

Talking about the wide-angle camera lens, it occupies a very large area inside the frame, but its edges have a circular distortion. Even after turning on the “Ultra Wide Lens Correction” option present in the camera app, we have seen the problem of spherical distortion in many photos. Apart from this, photos in low light from this lens come with dark and poor detail. Even the night mode does not show any good effect in pictures taken with this lens.

Live-focus mode blurs the background of the photos. The quality of the photos is good and its depth sensor also performs well to smudge the edges. Users can set the blur according to it.

It also has good pictures taken nearby. The camera can focus fast in good light. Subjects can be drawn very close to the macro camera. Colors are good in macro shots and there is plenty of detail in photos.


Video can be made up to 4K resolution in Galaxy A51, but does not include stabilization. Video is good in good light, but in low light, video gets a lot of grain. If you make a video at 1080 pixels, you will get a stable video, but the video shows a twinkling in the video. This shimmer is increased in low light. You can use the ‘Super-Steady’ feature in this camera app, which uses a wide-angle lens for video recording. In this, the video becomes stable, but the detail becomes quite bad.

The 32-megapixel camera on the front takes photos at 12-megapixel or 8-megapixel resolution by default. Selfie does not come clean many times in it. The camera makes the skin tone quite soft. Sometimes this softness increases so much that the selfie is blurred. The detail is good in low light, but there is a lack of sharpness.

Other camera modes include Pro, Panorama, Food, Hyperlaps, Super Slow-Mo and Slow Motion modes, which have also been seen in earlier Samsung phones. Bixby vision and AR emoji can also be accessed through the camera app. The Galaxy A51 also includes AR Doodle, which we have seen earlier in the Galaxy S10 series.


Samsung has launched the Galaxy A51 at a slightly higher price than the launch price of the Galaxy A50s. In lieu of this additional price, the company has given you a fourth rear camera, a more modern looking hole-punch display and more RAM. Currently, Samsung has launched only 6 GB variant of this phone in India, which costs Rs 23,999. The 8 GB RAM option is listed on the company’s website, but it is not yet available for purchase.

Power users will immediately argue that the Redmi K20 Pro with the same RAM and storage options at a price of only Rs 1,000 more than the Galaxy A51 will give better performance and to a large extent they will not be wrong either. In Redmi K20 Pro, you get a flagship-grade processor, HDR display, more premium build quality and better camera setup. If you will be gaming a lot, then yes, Redmi K20 Pro will be a better option for you. You can also get the Redmi K20, which is a capable mobile phone, for a small amount of money.

However, there are some options in the Galaxy A51, which some users may like a lot. Despite the high price, this phone will be liked by users seeking a simple and smooth experience. In this, you get the experience of Android 10. Along with this, the phone gets a slim and light body, Samsung Pay, good battery life, excellent display and of course the confidence of the Samsung brand. We would have liked to include a more powerful processor at this price. Apart from this, its slow biometric sensor and average camera performance also make the phone a step back.

Even Samsung Galaxy A50s at its new starting price (Rs 19,990) now offers good value. However, if you are looking to buy a smartphone that is not out of date quickly, then it would be prudent to buy the Galaxy A51, except the Galaxy A50s.
