Samsung Galaxy A51 Review |  Gadgets 360

Samsung is strengthening its A-series lineup with brand new models starting with the Galaxy A71 and Galaxy A51, which it announced earlier this month. The Galaxy A51 has already been launched in India at a starting price of Rs. 23,999. To keep the series fresh and relevant, the new smartphone brings a few updates to the existing Galaxy A50s (Review).

According to Samsung, the Galaxy A51 is one of the first phones in the series to sport an Infinity-O display and a macro camera. Apart from these highlight features, it has many of the same specifications as its predecessor, including its AMOLED display, processor, and design aesthetic. Apart from the Redmi K20 Pro (Review) and Redmi K20 (Review), there isn’t much competition at this price level, which could be an advantage for Samsung.

So, is this new lower mid-range offering worth considering considering the current competition? let’s take a look.

Samsung Galaxy A51 Design

The body design of the Samsung Galaxy A51 is similar to that of the Galaxy A50s. We have an all-polycarbonate body, which is quite light at just 172g, and also quite thin, measuring just 7.9mm in thickness. Fingerprints are prone to pick up on the shiny body, but they are not very visible on our Prism Crush Black unit. The rear finish is a bit slippery too, but thankfully Samsung provides a case in the box.

The biggest change is the Infinity-O display, which we are seeing for the first time on the Galaxy A-series phones. It’s essentially a single hole in the top middle of the display, similar to what we saw on the Galaxy Note 10+ (Review). Samsung may not have changed the body design much, but the hole-punch display gives this phone a premium look, which we appreciate. Galaxy A51 uses a Super AMOLED panel with full-HD + resolution, which produces attractive colors and good sharpness. It looks attractive from the front, thanks to the slim bezels around it.

Button placement is ergonomic, and on the right, we have a tray for two nano-SIM cards and a microSD card. On the bottom, we have the usual headphone socket, USB Type-C port and speaker grille. The back of the Galaxy A51 has a familiar looking camera bump, but now there’s a fourth camera. The bump doesn’t come out much, which is good.

The Galaxy A51 comes with the usual accessories, which are a 15W fast charger, a Type-C cable, a headset, a SIM eject tool and a case.

Samsung Galaxy A51 Specifications and Software

Samsung is stuck with the same Exynos 9611 processor as the Galaxy A50s, which feels a bit underpowered in 2020 and at this price. The Galaxy A51 is available with either 6GB or 8GB of RAM, and 128GB of internal storage in both variants. Other specifications include dual-band Wi-Fi 802.11ac, Bluetooth 5, GPS, NFC and FM radio. Normal sensors are present and this phone also has Widevine L1 certification. The Galaxy A51 supports Samsung Pay, so you can use it for contactless payments.

The software running out-of-the-box on this phone is Samsung’s One UI 2.0, which is based on Android 10. The new version looks and feels similar to the previous versions of One UI that we’ve used before, but Samsung has made some changes to improve the user experience. Now changing the wallpaper is very easy as there is a dedicated menu for it instead of being redirected to the theme app.

Other small changes include the position of the Allow Access notification from apps, which now appears at the bottom of the screen instead of in the middle. The ‘Device Care’ sub-menu also has a revamped look; Battery usage can now be tracked for the last seven days, not just the last time the phone was fully charged; And now you can change the lockscreen app icon, swap the default dialer or camera shortcut for DND or flashlight toggle.

There is still some bloatware pre-installed, including third-party apps and some apps from Samsung like Samsung Shop, but most of them can be uninstalled. Samsung has also added some India-specific features to the Galaxy A51, such as the ability to organize your SMS messages as a visual card, multilingual predictive typing and Smart Crop, which claims to detect the most relevant part of the screenshot. and lets you crop it with a single tap. We found that the Smart Crop feature works best if the screenshot contains an image.

Samsung Galaxy A51 performance and battery life

When it comes to daily use, the Galaxy A51 feels almost identical to the Galaxy A50. The slim and light form factor is something we really like. Navigating the interface was relatively quick, but it didn’t feel very fluid. There were a few instances when we noticed slight lag in system animations. Benchmark performance was good; What will be achieved on the lines of Qualcomm Snapdragon 660 or 665 SoC. Although at the price Samsung is asking for this phone, it is a bit heavy.

In AnTuTu, we got 1,86,220 points, while in GFXbench’s T-Rex test, we managed 42fps. The back of the phone did get a little warm when gaming and running stressful apps, but never got uncomfortable. Thankfully, the Exynos 9611 SoC is quite capable of graphics. PUBG Mobile and Asphalt 9: Legends both played well with good framerate.

Biometric authentication works well but it is a bit slow. The in-display fingerprint sensor takes a while before you can authenticate and unlock the phone, and it’s the same story with facial recognition.

The Galaxy A51 supports Dolby Atmos, but only if you have wired headphones plugged in. Audio quality is strictly average with the bundled headset, but this phone sounds better with higher-end after-market headphones. The bottom-firing speaker isn’t too loud, but enough for personal listening. The display is one of the best aspects of this phone. The brightness is great and the colors look vibrant, which makes any content very enjoyable to watch.

Samsung used a 4,000mAh battery for the Galaxy A51, and it posted a decent runtime of 14 hours 55 minutes in our HD video loop test. We easily managed to get through a full day of regular use, and there was enough power left to get us through half a day. There’s fast charging, and we managed to charge the battery to 67 percent in an hour. It took a little over two hours to fully charge it. It’s relatively fast, but not quite as fast as others in this segment, such as the Redmi K20 Pro, which charges up to 80 percent in an hour.

Samsung Galaxy A51 cameras

Samsung has added a new 5-megapixel macro camera to the three types of cameras that were on the Galaxy A50s. These include a 48-megapixel primary sensor; a 12-megapixel wide-angle camera; And a depth sensor of 5 megapixels.

In One UI 2.0, the camera app has been changed a bit, and now has slightly different looking icons. Most shooting modes are now bundled together in the “More” menu, but you can combine them in the main viewfinder interface if needed.

The main camera captures oversampled 12-megapixel photos by default but you can shoot at the full 48-megapixel resolution if needed. This option is hidden in the Aspect Ratio menu. In good lighting, the Galaxy A51 managed to take detailed shots of objects in the center of the frame. However, objects towards the edges generally looked a bit blurry and were comparatively soft.

In low light, the primary camera took great colors, and details were well represented without too much noise. There’s a dedicated Night Mode, but we didn’t find it to make a significant difference compared to shots taken in Standard Photo mode, as the Scene Optimizer automatically adjusts parameters when low light is detected.

The wide-angle camera captures pretty much any scene in the frame, but it does introduce some pretty bad barrel distortion. Even after enabling the “Ultra Wide Lens Correction” option, some shots still looked unnaturally distorted. Photos taken with this camera in low light looked darker and had poor detail. Night mode doesn’t help much here either.

Live-focus mode blurs the background for a more dramatic look. Image quality is good and the depth camera helps the Galaxy A51 do a decent job of edge detection. You can adjust the blur level here, but the extra effects for this mode like spot color, etc. that we’ve seen on other Galaxy phones, are missing.

The close-up also turned out very well. The focusing speed is adequate in good light and we were able to take some decent shots. You can get very close to your subject when using a macro camera. Colors weren’t bad and the sensor captures a lot of detail.

The Galaxy A51 can shoot video up to 4K, but without any stabilization. Video quality isn’t bad when shot in good light, but in low light, clips are grainy and details are weak. You get stabilization at 1080p, but as a result, there’s also a noticeable flicker effect while on the go. Consistent autofocus is also a bit sluggish. This shimmering effect is amplified in low light, and looks jittery. You can use the ‘Super-steady’ shooting mode, which uses the wide-angle camera to record video. Stabilization is better, but details are weak.

Depending on the perspective you choose, the front 32-megapixel camera captures 12-megapixel or 8-megapixel oversampled shots. Selfies were generally not very clear. Skin tone was smoothed out a bit and shots looked a bit dull overall. Detail was good in low light, but there was a slight lack of sharpness.

Other shooting modes include Pro, Panorama, Food, Hyperlapse, Super Slo-mo and Slow Motion, similar to what we’ve seen on Samsung phones before. You can access Bixby Vision and AR Emojis through the Camera app. The Galaxy A51 also supports AR Doodle, which we first saw in the Galaxy S10 series.


Samsung launched the Galaxy A51 at a slightly higher price than the Galaxy A50s (Review) when it first debuted. For this extra money, you get a fourth rear camera, a more modern-looking hole-punch display, and more RAM. Currently, Samsung has only launched the 6GB variant in India, priced at Rs. 23,999. Although the company’s website mentions the existence of an 8GB RAM option, it is not available yet.

Power users will immediately argue that the Redmi K20 Pro (Review) offers better performance for just Rs. 1,000 more, and the same amount of RAM and storage – and they won’t go wrong. On the Redmi K20 Pro, you get a flagship-grade processor, an HDR display, more premium materials and better cameras. If you do a lot of gaming, then yes, the Redmi K20 Pro will be the more sensible option. In fact, for a little less money, you can even get the Redmi K20 (Review), which is also very capable.

However, there’s a lot to like about the Galaxy A51, and despite its price tag, it will appeal to those looking for a polished experience. You get Android 10 out-of-the-box, a slim and light body, Samsung Pay, solid battery life, a crisp enough display, and of course the Samsung brand. We would have preferred a more powerful processor at this price; The biometric sensors are not the fastest and the overall camera performance is a bit low.

Even the Samsung Galaxy A50s now offers good value at its new starting price of Rs. 19,990. However, if you’re looking for something more future-proof, it makes sense to skip the Galaxy A50s and go for the Galaxy A51 instead.
