Samsung A51 Review 2020

Samsung A51 Review

Samsung has been firing on all cylinders with its budget series, which is known as the M series and the A-Series. The M series is known as the Millennial Series. It is a low and lower mid-budget smartphone. The A-Series, however, in the mid and Upper-Mid budget range smartphones. Here we will give a complete review of Samsung A51.

The A-series was the first-ever phones which were actually able to make a bridge between the flagship S series and the J series. Some consider that the A series has been introduced to unofficially announce the retirement of the all-time favorite J series.

But no matter the actual cause might be, we will be focusing on a single product from the series today. And that is the Samsung Galaxy A51. Some say that it is the Samsung Galaxy S10 but within your budget. But does the phone do any sort of justice to its ancestors or fails under immense pressure? We are going to find that for you guys. So do stick with us for the full review as we are going to tear this damn phone apart! Got scared? Just kidding! But we will certainly push it to its limit to actually see what this bad boy is truly made of.


The Samsung Galaxy A51 Review: The AMOLED Wonder or a Mid-Range Understatement?

The all-new Samsung Galaxy A51 has been another step further if we have to speak on an overall expression. But before going on to make a final expression, I would like to take a quick look at some aspects. These are:

  • Design
  • Display
  • Performance
  • Camera
  • Battery
  • Sensors and Other Features
  • Water Resistance

These aspects will give us a better understanding of the phone’s capability and ease of access. So let us not waste any time and jump into the segments real quick.


Design of the Samsung Galaxy A51: Mimicry of the Flagship using Plastic?

As you have read in the title, yes, Samsung A51 is certainly a mimicry of the Samsung S10 or S20. But the major difference is the performance and build quality. Unlike the shining glass and aluminum finish of the Samsung S series, this phone has been completely made out of plastic to cut down the costs basically. But oh, boy! Has Samsung done a great job?!

The phone has a dimension of 6.24 inches in length, 2.90in width, and 0.31 inches in the breadth. The frame and the back are made out of plastic, of course. But Samsung did what they are known as the best in the business. They have the A series in some type of illusion coloring, which reacts differently in different viewing angles and light setups. This is a unique persona overall, and the phone does give a good vibe altogether.

The biggest change perhaps in this year for the Samsung A51 from the Samsung A50 is the camera unit and the display itself. The camera unit is a quad-camera this time instead of the triple camera module of the A50. But the L pattern does bring the X Factor in the A51. The display has the signature punch whole display rather than an infinity notch. Other than that, the design, the attributes are quite the same as before. The phone is surprisingly light as far as the size is concerned. It is weighted around 172 grams. The lock and the volume adjustment rocker is on the right side. The left side housed the SD Card and Dual SIM Card Tray. On the bottom, you will be able to find the speaker, the all-important 3.5 mm headphone jack, and the USB type C Power cum Data port.

Other than that, everything is pretty basic as far as Samsung is known over the years. Now let us focus on the display for some time.

The Display of the Samsung Galaxy A51: The Signature AMOLED Display with the Punch!

Samsung is known best for its wonderful screens in their phones no matter what budget it comes in. However, Samsung has been generous in this particular model. They have installed their all-time best screen, the full high definition AMOLED display. The 6.5 inches Super AMOLED Screen just give a sucker punch to the haters. Speaking of the punch, Samsung has been like a Santa as they have provided with the trendy and desirable Punch hole camera module!

The screen has a resolution of 1080 pixels into 2400 pixels. Though the phone has no rounded or Edge display, the bezels are pretty thin. For that, the screen to body ratio is almost 87.4%. The aspect ratio is 20:9.

This display is no doubt the best in the business. AMOLED tech is almost used in many flagship smartphones of other brands as well. Samsung is the proud patent owner of this display tech. Having said that, this phone works brilliantly in all light conditions. It is pretty bright in higher light conditions. The NITs counts are pretty awesome by itself.

If you are into spending a lot of time on the phone’s screen or you use the phones as your entertainment purpose, then this display is only made for you. The color balance, sharpness, and details are just on the other level. Good job so far, Samsung!

Now let us move on to one of my favorite segments of a phone, which is the performance.


Performance of Samsung Galaxy A51: The Exynos Powerhouse or Disappointment?

Samsung has been a bit obsessed lately with their in-house chipset, Exynos. But as they managed to pull off yet another Snapdragon upset? Or failed to make a mark. We will see that in no time.

As you guys have guessed it right, we will be reviewing the hardware and the software units. Then we will be able to examine the collaboration between the two units. Remember, the better the collaboration, the more the chances of survival in this fierce market.


The Hardware of Samsung Galaxy A51

As I have mentioned earlier, the chipset is brought from their own backyard. The tech giant has installed a 10 Nanometer Octa-Core chipset, which is known as Exynos 9611. This chipset is clocked around 2.3 GHz for the first four cores whi9ch are Cortex A73, and the remaining four are clocked at 1.7 GHz, and they are the Cortex A53.

This chipset is very compatible for daily multitasking. But somehow, it is not as good as it used to be when it is put through heavy and intense gaming. So if you are into gaming, you might seek some glitches or frame drops.

On the other hand, the RAM is of three variants. The basic level is 4 GB, then 6 GB, and lastly 8 GB. The internal storage is available in 64 GB and 126 GB.  There is a dedicated micro SD card slot. So, for heavy consumers in terms of space, they can easily install an External Micro SD Card.

Now let us talk about the software of the all-new Samsung Galaxy A51.


The Software of Samsung Galaxy A51

The phone runs in the latest version of Android, which is the all-new Android version 10. There is no report or clarification for the upgradable scenario later on in the distant future. But let that be under the hands of the tech giant.

There is a new UI introduced in this all-new phone. It is known as One UI 2.1. This particular UI is basically the refined version of the stock android with some sugar and spice from Samsung. Perhaps the fast transitions and the all-new dark mode is pretty hectic in this particular UI.

That means you can select the dark mode, and almost all the Google Apps and the UI will be in the dark mode, which is basically in charge of saving a little bit of juice.

Overall speaking, I am a little bit disappointed with the performance. Truly speaking, good brands are also launching phones in a similar price range. But their performance is a bit higher than the Samsung A51. As I was writing the Samsung A51 Review, I was very disappointed as well. But on the bright side, this phone is for those who think that the Samsung Logo is smart and trustworthy.

Now let us move on to rather one of my most awaited parts of a phone—the Cameras of Samsung Galaxy A51.

Samsung S20 Review

The Cameras of Samsung Galaxy A51: The Quad Camera delight or disaster?

The few changes that are directly visible this time for the A series is perhaps the Rear L pattern Quad cameras. On the rear camera module, the main camera is a 26 mm wide camera of 48 Mega Pixels with an aperture count of f/2.0. The Second Camera is a 123 degrees Ultra Wide Angle Camera of 12 Mega Pixels. The aperture count of the second camera is f/2.2. The third camera is a macro lens. It is of 5 Mega Pixels, and the aperture count is f/2.4. The last camera is actually a depth sensor, and it is an f/2.2 % Mega Pixels sensor. The front camera is a 26 mm wide-angle camera of 32 Mega Pixels. It has an aperture count of f/2.2.

The camera performance, in my opinion, was decent, not that amazing, which the setup could have offered. The images were good in bright light conditions. But there was some visible noise. The 48 Mega Pixels could do anything extraordinary other than making huge sized image files. The Ultra-Wide camera did a decent job as well. But all fall apart a little bit when it comes to low lights. The night modes do save some of the reputations, but it is pretty minimal.


The selfies came out quite nice, and I am satisfied with the selfies. As far as the videography is concerned. The rear camera can record up to 4k resolution at 30 frames per second. But there is no image stabilization for that resolution. However, in 1080p, the OIS is available, and the image stabilization is pretty good. In the Ultra-Wide camera, you can also record some 1080p with great image stabilization. The front-facing camera, AKA, the Selfie camera, also can shoot up to 1080p at a frame rate of 30 frames per second.

So, overall speaking, I am slightly disappointed with the camera module as well. But Samsung could have done much more at this price point. Comparing these cameras to the equivalent cameras in the other brands, The Samsung Galaxy A51 does fail to excel.


The battery of Samsung Galaxy A51

It comes with a non-removable 4000 mAh battery with fast s=charging supportive up to 15 Watts. It might not be the fastest out there but fairly workable as we have noticed that it can charge your phone up to 35% in the first 30 minutes.

Sensors and Other Features

The fingerprint scanner is an in-display optical fingerprint. Not the fastest but workable. All the other sensors, like the accelerometer, gyro, proximity, compass, and ANT+, is included in the phone.

Water Resistance

None mentioned in the campaign.

Advantages and Disadvantages


  • Great Display
  • Good Built quality


  • Cameras not up to the mark
  • Weak processing power


FAQs of Samsung Galaxy A51

Wrapping Things Up!

After writing the Samsung A51 Review, We have finally come to the very end of it. I must tell you. This phone has an amazing design and a great display. But Samsung could have done better in the processing power and the Cameras. But all they did was to create a hype and not quietly living up to that. So that was all for today. I will see you guys next time!
