Samsung Galaxy A52. Interesting evolution-in-depth description
Samsung’s a-series smartphones are among the best-selling phones in the world. In 2019, the top 5 worldwide sales included 3 smartphones of this line, as well as two iPhone models. A similar picture was observed in 2020.

Of course, these ratings and sales volumes are not directly related to product quality or optimal performance.

On the contrary, the fact that in the list of smart phones best sellers are often the initial model of the series (Galaxy A10, Galaxy A01), says the opposite-people often do not care so much for the features and quality (Samsung, these models do not release), as the brand. After all, Chinese manufacturers in the budget segment offer much better characteristics.

Samsung Galaxy A52, we examined in detail its main competitors (Redmi Note 10 Pro, Poco X3 Pro) to analyze the novelty of Samsung in this context.

At first glance, there are many changes to the Galaxy A52. This is an excellent protection against moisture, stereo audio, the failure of failed Exynos processors, new high refresh rate displays and much more. But there are things that Samsung prefers not to advertise too much. We will talk about all this in the review.

Samsung Galaxy A52 Review. Hardware specifications and general information
The camera module moves smoothly on the cover, only slightly protruding above it, due to the fact that the smartphone does not swing sideways when lying on a flat surface (this is a big problem on the Redmi Note 10 Pro):
The cap itself is quite thin. Even if there are no scratches or abrasions on the case during use, it is only a matter of time. This is what the “flagship” polycarbonate of the Galaxy Note20 looks like after six months of careful use without a case:
The build quality is good. The body does not creak, the movement of the buttons is clear. After 4 years, moisture protection returned to the A-series.only if in the Galaxy A5 (2017) it was the IP68 standard, now the IP67 standard is used. In any case, it is a good advantage over competitors who do not always have IP53 protection (against splashes and rain).

Plastic is not only the back cover, but also the side frame. The screen is covered by a Gorilla Glass 5 protector. It will not save you from scratches, but it will withstand the fall.

There are no elements on the side face, but on the right there is a volume rocker and a power button:

On top there is a microphone for noise cancellation and a combined slot for SIM and memory card:
Interestingly, the audio duct of the second speaker does not come out on the top edge, as is the case with some competitors with stereo speakers (Redmi Note 10 Pro, Poco X3 Pro). That is, the sound passes only through the speaker grille on the front side.

Under the speaker grill is a cutout of the selfie camera and a little to the left of it under the screen is hidden a light sensor. At the bottom, also under the screen, there is a fingerprint scanner:

Fingerprint recognition is more or less fast and stable. The only uncomfortable point is that you can record only 3 fingers, which is quite unusual. Of course, no one prohibits engraving two fingerprints on one finger at once, but in this case recognition may not work stably.

Another uncomfortable point is due to the proximity sensor. He’s not here. For some reason, some manufacturers are constantly trying to experiment with this sensor, replacing it with a speaker and microphone (ultrasound on Redmi Note 10 Pro), and then completely removing it, simulating its operation with a touch screen.
Here is the second case. Samsung Galaxy A52 turns off the screen at the time of the call by analyzing the touch screen. If the contact area is large (that is, you do not press the finger, but touch the cheek), the screen will turn off.

In general, there are no serious problems with this, but classic infrared proximity sensors work more reliably and stably.

At the bottom is the 3.5 mm jack, the main microphone, the USB-C jack and the main speaker:
The quality of the stereo speakers is good, approximately at the level of Redmi Note 10 Pro. Difficult to detect differences by ear, the instrument shows a small difference at low frequencies (Galaxy A52 reproduces them a little quieter) and in the mid-range (from 400 to 900 Hz, even a little quieter). But in general, the sound of the Galaxy A52 is on par with the best solutions of the competition. This is a big jump compared to previous models.

The sound of wired headphones is also not bad. At least this is more interesting than the Redmi Note 10 Pro or Poco X3 Pro-the sound is more detailed, which is clearly audible in heavy music (Rock, Metal).

With wireless audio (especially for those with Samsung headphones), things are even better. It supports the patented Hi-Fi Scalable Codec (adaptable to analog aptX) and Dolby Atmos technology. In this budget, probably, no one else offers such options.

Among the unpleasant features can be noted the lack of aptX HD and aptX adaptive codecs.

In addition, the slightly outdated version of Bluetooth 5.0 does not imply future support for the new low-power wireless audio standard (Le Audio)and the LC3 codec.

Other interesting features include an audio adaptation system to the physiological characteristics of the user( Adapt Sound), an integrated equalizer and exclusive software.

The quality of communication on the Galaxy A52 is not bad. LTE-Advanced standard with frequency aggregation (simultaneous connection to a base station on multiple frequencies) is supported, which greatly increases the speed of 4G Internet.

Wi-Fi works in two bands (2.4 and 5 GHz), GPS-on the same frequency. Working accuracy in application test-standard 3 meters:
The vibration motor remains the same – it is a primitive ERM motor with an eccentric that does not cause pleasant tactile sensations. In comparison, Xiaomi smartphones are using linear vibration motors for the second year. And in this regard, Samsung is far behind.

There is no LED indicator of missed events. Instead, the AOD functional mode is used(we’ll talk about it later).

For contactless payments there is an NFC module (depending on the region, Google Pay and Samsung Pay systems are supported, MST technology is not supported). There is also an FM radio that works only when wired headphones are connected.

Samsung Galaxy A52 screen overview
The smartphone has a Super-AMOLED display with a diagonal of 6.5 ” and a resolution of 1080 x 2400 pixels (aspect ratio 20: 9). The image clarity is good, the pixel density is 407 ppi, which is even higher than that of the flagship Galaxy S21+.

The screen supports HDR, even if only on YouTube. In the Netflix app, videos are streamed in a standard dynamic range.

The brightness of the smartphone is very high (up to 800 nits in automatic mode in the sun), but when looking at HDR, it is inferior not only to the Samsung flagships, but also to the Redmi Note 10 Pro. The latter is noticeably brighter:
In the settings you can select the display mode: natural (sRGB) or saturated (DCI-P3) colors. In the latter case, the Galaxy A52 looks much more professional than Xiaomi’s screens. I remind you, Redmi Note 10 Pro in saturated color mode is not able to adequately display normal content (not HDR), because of what the colors look unnatural (too saturated):
In HDR mode, the screen of the Galaxy A52 shows a juicier image. That is, in terms of color rendering, Samsung still leaves competitors behind.

In addition, for the first time in the A-Series appeared screens with an increased image refresh rate-90 Hz. Of course, this is not 120 Hz flagship models from Samsung, but the difference with the usual 60 Hz is also strongly felt.

The interesting thing is that the frequency here is fixed-either 60 or 90 Hz. Adaptive mode, as on Galaxy S21, Redmi Note 10 Pro or Poco X3 Pro, No. Even when watching videos on YouTube at 30 frames per second, the smartphone updates the image on the screen 90 times.

Other useful features include glove management mode — increased screen sensitivity), screen on and off with a double touch (mechanical button, you can not use) and, of course, Always On Display – time, date and notifications display mode on screen off:

Traditionally, for AMOLED displays, brightness control is via PWM. But if many smartphones harmful Flicker is minimized with the DC Dimming function, here PWM fully manifests itself. So, if you are sensitive to flicker, pay attention to this point.

The last thing I would like to mention is the “comfort for the eyes”mode. Here came the adaptive mode, which some people mistakenly confuse with Apple’s True Tone technology:
On the iPhone, it is a much more complex imitation of reflected light, and on Samsung, a simple reduction in blue light depending on the time of day (the later, the more yellow the screen turns).

Battery life and performance of the Samsung Galaxy A52
Compared to previous models of the A-Series, the battery capacity of the Galaxy A52 has increased by 500 mah. This is enough not to worry about autonomy.

In the 90 Hz screen mode of operation, even with very active use + always on the Display, the smartphone will easily last a day on a single charge. Screen operation time can reach 6-8 hours:

At night it takes no more than 2% charge (all communication modules are included, the settings are not optimized).

The full power supply is rated at only 15 W, although the smartphone itself supports charging at 25 W. from zero to 50%, the Galaxy A52 is charged with a full power supply in 40 minutes, the full charging time is 1 hour 35 minutes. When using the brand 25W power supply, the charging time from zero to 50% is 26 minutes, the full charge time is 1 hour and 10 minutes.

You can compare these results with those of the competition (the values in the table are indicated with the supplied power supplies):

Smartphone Battery Up To 50% To 100%
Galaxy A52 4500 mAh 40 min 95 min
Redmi Note 10 Pro 5000 mah 25 Min 60 Min
Poco X3 Pro 5160mah 25min 60min
Wireless charging is not supported, but the smartphone can be used as an external battery and charge other devices via cable (this option is present on other Samsung smartphones):
As for performance, of course the Exynos processor also went with the A-Series.why it happened like this and why it is a good thing, we have already said in a first look at the Galaxy S21 Ultra.

The new Galaxy A52 works with last year’s Snapdragon 720g chipset. this processor has been used in smartphones such as Vivo V20, Redmi Note 9 Pro, OPPO Reno4, etc.

This is a good solution for mid-range smartphones, albeit a bit dated. The processor does not overheat, the trottling test passes “at once “(both in 20-thread and 100-thread mode):

Heavy games, such as PUBG Mobile, go to high (but not maximum) settings. Play comfortably, but no more. This pleasure of games like Samsung flagships or smartphone Poco X3 Pro, here you do not get.

There are no problems with heating, even during games.

In the Antutu test, the device earns about 260 thousand points (this is a typical indicator for the Snapdragon 720g platform):
The system is generally fast and smooth, but there are some optimization problems. Sometimes slowdowns (and noticeable) occur in the camera, when creating screenshots or when switching from a heavy application (for example, a game and a browser with several open tabs).

This could be due to the amount of RAM (4 GB), although almost always less than 3 Gb are occupied. The permanent memory capacity is 128 GB (type-UFS 2.1), the maximum read speed is about 560 MB / s.

Samsung Galaxy A52 camera review
In short, we list the list of all smartphone cameras:

Main: 64 MP, f / 1.8, 26mm, 1/1. 72″, 0.8 µm, PDAF, OIS
Ultra wide angle: 12 MP, f / 2.2, 1.12 µm
Macro: 5 MP, f/2.4
Depth sensor: 5 MP, f/2.4
Selfie: 32 MP, f/2.2, 26mm, 1/2. 8″, 0.8 µm
The depth sensor is used here rather for marketing purposes, as it may have been successfully replaced by an ultra-wide-angle camera. However, it works well. In simple terms, the limits of the main object are determined quite accurately:
But in very complex scenes, portrait mode crashes. This is clearly visible in the following example (note the peacock tail scraps in the top left corner):
The Macro camera, despite the relatively high resolution, is significantly inferior to the similar camera on the Redmi Note 10 Pro. The main claim of this module is the lack of autofocus, which does not allow you to get very close to the subject (the maximum distance is ~4 cm).

Here is a visual comparison of the features of two macro cameras:
Thanks autofocus macro-storage on Redmi Note 10 Pro allows you to shoot with closer (in the photo the approximation is shown).
The ultra-wide-angle camera is noticeably superior to similar modules on Redmi Note 10 Pro or Poco X3 Pro.

With good lighting, this camera takes relatively high quality photos with high detail and wide dynamic range:
The sharpness of the frame is slightly reduced at the edges, which is quite normal for a mid-range lens.
The camera can also be used indoors in low light conditions. The colors remain saturated, the detail is maintained at an acceptable level:
In short, the ultra-wide-angle camera can be used here. This is a perfectly working tool.

Now let’s talk about the main module at 64 MP. Whose matrix is used here is difficult to say. This is a Sony imx682 or Samsung GW1 sensor (as in the Redmi 8/9 Pro lines). Device Info HW app doesn’t add clarity:
It is possible that the type of sensor depends on the region of sale. Samsung has repeatedly made such a trick (for some regions, instead of the declared sensor, Sony installed a similar module of its own production).

In any case, the main camera here is one of the best in this price segment.

Photos are juicy, but not too saturated. The level of detail is as high as 16 MP:
Of course, with careful consideration, processing artifacts are visible in the photo (especially on a blurred background), but the results can vary greatly from Snap to snap depending on the settings selected by the automation.

Sometimes algorithms artificially increase sharpness and contrast. In general, this does not affect and also makes the picture more impressive:
But with maximum approximation it is clearly visible and in many cases I would like to see a less aggressive treatment:
Too bad that the camera application does not allow you to save images in RAW format. But you can install third-party applications that support RAW (such as Lightroom or Open Camera). The result in RAW turns out to be interesting, you can ” throw “the details in the shadows or return the”burned” areas in the pictures.

If we compare RAW on Galaxy A52 and Redmi Note 10 Pro, the latter wins due to a larger sensor and a bright lens (less noise and a wider dynamic range). Of course, both cameras are far from the RAW file of the flagship S21 Ultra.

In addition to the lack of RAW in the stock application, another drawback can be considered that it saves a lot of time when shooting at 64 MP (up to 3 seconds).
There is no telephoto lens here, but 2x zoom is available on the camera interface when taking photos at 16 MP:
At night, the Galaxy A52 does a good job because of the night mode. The number of details is obviously reduced due to the strong noise reduction. But in general the picture looks good:
In Pro mode, you can manually change the light sensitivity (ISO – 50 to ISO-3200), shutter speed (up to a maximum of 10 seconds), white balance, focus and many other options:
In total, the following shooting modes are available on the smartphone:

Ar-sketch
Panorama
Food
Professional Video
Ultra slow shooting
Slow motion
Hyperlapse
Multi-frame
Fun
Macro photography
Portrait
Of
Night
Video recording
There is also an artificial intelligence that analyzes the scene and automatically selects the optimal shooting parameters, there is a QR code scanner, an HDR mode, voice control of the camera and save photos in a new high-performance format (HEIF).

As for video recording, the smartphone supports the following modes:

HD (720p), 30 fps
FullHD (1080p), 30/60 fps
4K, 30 fps
The main camera has optical stabilization, which is quite rare in this segment. It allows not only to stabilize the video, but also to take brighter and clearer photos in low light conditions.

This is what the shooting looks like in 4K:

And when shooting in FullHD (30 fps), the Super stabilization mode (collaboration between optical and electronic stabilization systems) is also available. Here is an example of such a video:

Overall, the Galaxy A52 is a big leap in quality for Samsung in the average budget. There were still no such good cameras in serie A.

As for the software, the Samsung Galaxy A52 runs the proprietary One UI 3.1 shell based on Android 11. This is one of the most interesting and functional shells, and then read the details about it in a separate material.
Summarize
Samsung Galaxy A52 turned out to be very interesting and in a way a somewhat paradoxical product.

On the one hand, we see a rather high price and savings on the little things: poor equipment; no proximity sensor; too short USB cable, which is extremely inconvenient to use; a good macro camera, which spoiled the fixed focus; 4 GB of RAM in the basic configuration
But on the other hand we see the attention to other small things: Dolby Atmos technology; optical stabilization of the camera; good stereo sound and good sound in the headphones; IP67 moisture protection; support for long-cycle smartphones.

Does the Galaxy A52 have advantages over Poco X3 Pro? Absolutely. This is a much more expensive display, a more interesting camera, a more modern design with a wide range of colors for coloring. But, of course, in terms of performance, Samsung’s novelty is much inferior to Poco X3 Pro. If you need a gaming smartphone, it’s very stupid to choose the Galaxy A52.

The Redmi Note 10 Pro also does not look like an obvious winner, although it has a more attractive price. At the moment, the Galaxy A52 camera in automatic mode shoots better, especially in low light and full resolution. The display is of higher quality in DCI-P3 mode, but also more harmful to those who listen to PWM. The ergonomics of the A52 is better due to the locking of the cameras.

Although both devices (Note 10 Pro and Galaxy A52) do not have a proximity sensor, there are more problems on Redmi Note 10 Pro with it.

On the other hand, the Redmi Note 10 Pro is a good device, with a 120 Hz AMOLED display and a potentially good camera. The equipment is an order of magnitude better.

Galaxy A52-this is by no means the best value for money. No Samsung smartphone has claimed this. It is necessary to understand that this is a brand a product, which by definition should cost more.

If you are a fan of Samsung and are thinking about changing your Galaxy A50 / A51 (or an older model), then the novelty definitely deserves your attention. This is the best model of the A-Series in recent years (this is exactly the Galaxy A5X line).
