Samsung Galaxy M21 and Galaxy A51 - comparison of smartphones

Galaxy A51 is one of the most popular smartphones available in the market today. Samsung managed to make a device that surpassed many Chinese devices in technical terms, which were previously considered the undisputed market leaders. A high-quality AMOLED screen, an excellent camera, an attractive design and an abundance of technical gadgets like an on-screen fingerprint scanner, coupled with a low price, did their job, and now it is believed that the Galaxy A51 simply has no competitors. Perhaps this is true. But you still can’t call this smartphone ideal.

Galaxy A51 is a good smartphone, but not without its flaws

Galaxy S21 in Russia fell in price by 25 thousand rubles

Let's decide on the shore: the Galaxy A51 is my wife's main smartphone. So, although I personally have not used it, it is constantly present in my mind, I know about all its features, disadvantages and advantages, which I will outline below. And whether to buy it or not, decide for yourself, based on your personal preferences and willingness to put up with the compromises of this device.

What the colors look like

The design of the devices is particularly attractive, but everyone has different tastes, so let's not judge the appearance. Galaxy M21 has 3 colors: green, blue and black. 3 colors are used as a solution for the Galaxy A51 case: black, red and white. Both phones are available in the same number of colors.

Size and weight

For reference: there are 2.54 cm in one inch.

What's better - a large display that's easy to watch videos on, or a compact phone that fits easily into any pocket? There is no clear answer. In our case, we note that the screen diagonal of the Galaxy M21 is slightly smaller than that of the Galaxy A51. Please note that smartphones differ in thickness and weight: the Galaxy A51 is thinner and slightly lighter than its opponent.

Galaxy A51 screen

However, there is something to praise this smartphone for. I will not dwell on subjective factors such as design, camera design and memory capacity, since everyone has their own criteria for coolness. I will only voice those aspects that are objectively cool.

The screen of the Galaxy A51 is really very cool

First of all, this is the screen. I’ve never had any complaints about Samsung screens before, but the Galaxy A51’s matrix is ​​simply amazing. This manifests itself even in idle mode, not to mention when in use.

• Firstly, it seems that the screen is a super-high-quality printed glossy picture that you move your finger over.
• Secondly, the AMOLED screen has a very low minimum brightness, and it is convenient to work with the smartphone in the dark.
• Thirdly, AMOLED supports Always-On Display mode, which allows you to display clocks, notifications and other information on the off screen without turning it on entirely.

Display

Let's now compare the main characteristics of the display. We will be interested in pixel density, resolution and other available parameters.

What can you say based on the data in the table? Judging by the table, the Galaxy A51 is better in terms of the specified characteristics and scored .

Processor, memory and battery

This section presents a block of data that allows you to understand how significant the difference in performance is.

We are tied in terms of the number of likes. The Galaxy M21 received likes for its battery capacity, talk time and Internet browsing time, while the Galaxy A51 received likes for its internal storage and RAM.

Galaxy A51 unloads apps

One UI doesn't hold apps at all, and it's inconvenient

Well, the third drawback of the Galaxy A51 is applications that do not stay in the RAM at all. I admit that this is a problem with all Samsung devices in general, but out of about two dozen running programs, after an hour, at best 3-4 remain running in the background. All other One UI knocks out of memory, forcing them to start cold.

The experience of using the Samsung Galaxy A52 is cool, but with disadvantages

I can't say that this is particularly annoying. But, firstly, because of this, sometimes there are problems with notifications, which is quite inconvenient, and, secondly, re-launching applications takes longer. That is, if they were working in the background, the smartphone would pull them up from there much faster than now.

Camera

We all love high-quality photographs. Let's compare the parameters that determine them.

If you often shoot outdoors, then you will need a zoom, then the Galaxy A51 is better suited for these purposes. Note the differences in the front cameras - the Galaxy A51 camera has a slightly higher resolution, which is important for many.

Fingerprint scanner does not work

The fingerprint scanner is the worst feature of the Galaxy A51

Perhaps the main drawback of the Galaxy A51, which everyone who has used it knows about, is the fingerprint scanner. Despite the fact that the smartphone seems to be equipped with a new generation module, which is better than the one that came with the original Galaxy A50, it is still impossible to use.

This scanner never works the first time. Moreover, even from the second it most often does not work, forcing you to change the location of your finger 3-4 times. As a result, unlocking takes quite a long time, and most often it is easier to simply enter the password.

The price of the Galaxy A51 in Russia has dropped below 15 thousand rubles. How is it better than the Galaxy A52

There was a case, I tried to somehow speed it up, and I even seemed to have succeeded, because the scanning began to go faster. But the need to change the position of the finger (and no one knows how to do it correctly) remains 3-4 times.

That's why my wife even refused fingerprint scanning in favor of facial recognition. Not to say that this technology works absolutely perfectly, but it is clearly better than an under-screen fingerprint scanner, which, apparently, is not intended for this at all.

Other properties

To complete the picture, we present some more data from the compared models. Perhaps one of them will determine your choice

We have made all the main comparisons. We hope you now have enough information to make your choice.

Which phone to choose: Samsung Galaxy M31s or Galaxy M51?

However, the most important comparison of all five today will apply to the Galaxy M31s and Galaxy M51. These are smartphones designed for the mid and upper mid price range. The price difference between the devices is about 6,000 rubles , but what do we get in the package? Let's start with what both devices have the most similarities to each other, and it turns out that there are a lot of these common features.

Both devices have an excellent display with Super Amoled technology. In this regard, it is worth noting that the Galaxy M51 is slightly larger than the Galaxy M31s, but this is not a disadvantage or an advantage, but only a feature that should be considered when choosing between these two devices.

Another common feature of both smartphones is the same camera. There is no need to dwell on this issue in detail, because there is not the slightest difference between them, not even in focal length or aperture size.

Both the first and second smartphones feature a quad-camera setup that includes a wide ultra-wide-angle lens, a depth sensor, and a macro lens. The same applies not only to the rear, but also to the front camera.

In fact, the biggest difference between these smartphones is that the Galaxy M51 uses a Qualcomm processor and that the device comes with a 7,000mAh battery.

However, in the case of the M31s, which is based on the Exynos chipset and has a 6000 mAh . However, is it worth the extra 6,000 rubles ? While it may seem that the Galaxy M51 will be better in terms of performance and battery life, in reality these differences are minimal and quite difficult to notice in everyday use.

In fact, buying a Galaxy M51 for that amount is definitely not the best investment. There are many cheaper models, but from last year, which do not differ either in characteristics or in appearance.

Similar smartphones to Galaxy M21

Based on a comparison of all the main characteristics, we will build a table of smartphones similar to the Samsung Galaxy M21:

Which phone to choose: Galaxy M11 or Galaxy M21?

There is no point in comparing all smartphones at once, so let's start with the first pair of Galaxy M11 and Galaxy M21. Both devices come from the same shelf and cost less than 20,000 rubles . In fact, the difference between these smartphones is about 3,500 rubles, and how does this affect the quality of the phones? In this case, we can definitely say that choosing a cheaper model is unprofitable, and there are several reasons for this.

Let's start with the display: the one equipped with the Galaxy M11 is a PLS TFT of average quality, with worse color saturation and viewing at angles, while the Galaxy M21 is a Super AMOLED, characterized by a really high quality. Other significant differences also relate to the camera and battery capacity.

While both smartphones feature a triple camera setup, the Galaxy M21's lenses have larger sensors to capture more detail. Every lens on the Galaxy M21, both front and back, is larger than the Galaxy M11. Finally, it is worth mentioning the battery, which in the cheaper model has a capacity of 5000 mAh , and in the more expensive one - 6000 mAh . The price difference is only 3,500 rubles , and within its framework we get a device with a better screen, camera and battery.
