The Samsung Galaxy A50 is a smartphone that intends to offer the best of the brand for a price that places it within reach of more purses than the high-end represented by the S10. Indeed, this model landed at the price of 349 euros, almost half the size of the Galaxy S10e, but everyone does not really need what brings more the latter.

However, discovering the Galaxy A50, we are in known terrain. Obviously, we are facing a Samsung: design, manufacturing quality, attention to detail

With a price of about 350 euros, the Galaxy A50 will find on its way a strong competition for a battle of high flight where it will oppose to smartphones better equipped with regard to processor power and technical specifications its quality of manufacture, its design and its homogeneity .

This Galaxy A50 smartphone has a 6.4-inch screen that incorporates a fingerprint reader, a technology that is still struggling with physical drives in terms of recognition speed and operational flexibility. During our test, we had several failures that were difficult to explain.

The bottom of this model contains a processor Exynos 9610 designed and manufactured by Samsung. This chip has a great smoothness of engraving, 10 nm, which is synonymous with good energy efficiency. It includes a total of 8 cores organized in two quartets: 4 Cortex-A73 cores at 2.3 GHz and 4 Cortex-A53 clocked at 1.7 GHz for tasks requiring less power.

Triple camera

This processor can count on the presence of 4 GB of RAM while the storage is entrusted to 128 GB internally. A rather generous amount, but, if that's not enough for you, a microSD slot is also there. It supports cards up to 512 GB.

The Samsung Galaxy A50 also relies on a large battery, since its capacity is 4000 mAh. The smartphone also has a fast charging technology.

Let's finish this first tour of the owner to signal at the back of the mobile the presence of a triple camera, while the front camera takes place in a small notch like a drop of water.

The set measures 158.5 x 74.7 x 7.7 mm and weighs 166 g.

Ergonomics and design

Like almost all smartphones of the moment, the Samsung Galaxy A50 seeks to maximize the space occupied by its screen.

In this case, it is doing pretty well, since its slab of 6.4 inches occupies 86% of its facade. For this, the borders have been reduced, but Samsung has not retained the punch solution for the front camera, which implements a more expensive technology naturally reserved for the time at S10.

Instead, we are dealing with a small notch that encroaches very little on the display surface. The Galaxy A50 maintains a certain compactness with regard to the large size of its screen, but it is nevertheless difficult to use 100% with one hand.

From the "glasstic" on the back

Unlike high-end, this smartphone does not use glass at the back. Instead, always to limit the costs and the final price of the terminal, Samsung opted for a material named Glasstic. The name is unambiguous: it is a plastic that wants to imitate the glass. The effect is rather successful with the bonus of a good resistance to invasive fingerprints … at least in the blue version received for our test.

The cameras protrude very slightly from the rear of the hull, just to sublimate very attractive lines. The quality of assembly is in tune: on this level, the A50 has nothing to envy to the Galaxy S range, even if it is a cross on the seal. Good point on the other hand for the conservation of the headphone jack in addition to USB-C.

The screen

Unsurprisingly, Samsung relies on the screen of its Galaxy A50 on a technology that the manufacturer masters perfectly: the Super AMOLED. The 6.4-inch diagonal slab is in 19.5: 9 format and displays a definition of 2340 x 1080 pixels. This translates into a density of 401 dpi.

Excellent numbers that provide a display finesse quite satisfactory. The colorimetry is average, with a marked drift towards cold colors such as blue and green, ultimately leading to a U'V 'delta of 0.027. Let's note in passing an almost perfect reproduction of the reds

Readable in all circumstances

Once again, Samsung offers a smartphone capable of showing a very low directivity. The measured loss of luminosity is limited: from 205 cd / m2 seen from the front, it goes to 189 cd / m2 once the smartphone inclined at 15 ° and 150 cd / m2 at 30 °.

The screen of the Galaxy A50 remains legible in all circumstances, including when you do not stand perfectly in front of him. The dynamics between the dark and bright areas remains average while the contrast tutles the vertices, with a rate measured at 476: 5 when the screen is set to 5% white.

The user interface

It is well over time Samsung interfaces heavy and not very ergonomic. With OneUI, the developers of the Korean brand have drawn a light overlay and very complete that goes like a glove to Android 9.0. You will find on the A50 most of the assets deployed by it: dark mode, settings menu redesigned, advanced gesture controls …

Of course, the presence of an AMOLED screen is used to offer the Always On mode which allows to permanently display a certain amount of information such as time or date. The personalization fans will not be left behind thanks to a well-stocked library of themes.

Performances

With its complex architecture processor to offer a good compromise between power and energy consumption, the Samsung Galaxy A50 displays a good daily fluidity. It will be hard to deal with the most greedy games where the number of frames per second falls rather quickly.

Submitted to our JavaScript test, this smartphone mid-range is doing well against very light processes with a response time of 87 ms for a restitution of 11 fps. But the heavier processes highlight the limits of this mechanism: the very complex processes painfully reach the 2 fps for a response time of 500 ms.

Photo and video

The back of the smartphone hosts a triple camera that consists of the following: a 25-megapixel main sensor coupled with an optics f / 1.7 equivalent to a 26 mm; optics opening at f / 2.2 ultra wide angle equivalent to a 13 mm which is associated with an 8 megapixel sensor; a third module based on a 5 megapixel sensor whose purpose is to provide additional information on the depth of field.

Note that the main sensor does not produce images of 25 megapixels, but 12 megapixels.

Perfect focus

The focus is perfect with a very fast autofocus that avoids most fuzziness.

The difference in quality of shots captured in 12 and 25 megapixels is tenuous, even undetectable: as much "to be satisfied" with the first resolution which allows in addition to take advantage of the excellent work of the automatic HDR mode that easily opens some scenes to the complex light. Our laboratory measurements on the single main sensor confirm our impressions.

The Galaxy A50 produces homogeneous images and perfect centering, Making it very easy to reframe. The optics are simply excellent with chromatic aberration almost zero, while no astigmatism is noticeable …

The only defect for this optic, a slight geometric deformation has been observed.

It is unfortunately not the same story for the sensitivity of this photo module that struggles to restore a satisfactory level of detail. The offending ? Maybe some imprecise digital processing which could possibly improve by an update of the smartphone.

An average frontal device

The 25 megapixel front sensor does not get any better in this exercise with a lack of flagrant detail. The sensor on the front unit lacks a lot of homogeneity. Too bad, because its optics is very good without chromatic aberration, astigmatism or distortion. In practice, selfies can however be exploited on social networks, but do not expect much better.

The ultra wide-angle module is rather successful, with a reasonable level of deformation and good management of shooting conditions. The portrait mode remains correct, no more, with difficulties to discern heads too ruffled.

Audio rendering

By keeping its headphone jack, the Samsung Galaxy A50 probably satisfies many users who do not want to cross the course of Bluetooth. This headphone output just like the speaker do the job.

The HP is a good power with a curve that makes good sense to mediums. The smartphone offers many adjustment possibilities and benefits from the Dolby Atmos certification: it is therefore possible to adjust the sound produced to suit its tastes.

Reception quality (radio performance)

The modem built into the Exynos platform gives it compatibility with the LTE Cat12 standard, ie a theoretical maximum download speed of 600 Mbps: what is it? take advantage of 100% of the network currently implemented by French operators.

Our tests are also interested in 2G and 3G. In 2G, the Samsung Galaxy A50 does not behave at all like its big brother, the S10. The weakness noted against the latter in terms of sensitivity on the GSM 900 band disappears completely on the A50 which is itself lower on the GSM 1800 band.

For 4G, our measurements highlight disparate results across frequency bands with scores ranging from the average on bands 3 (1800 MHz) to the excellent on bands 20 (800 MHz). Overall, Galaxy A50's radio performance is satisfactory and this mobile should allow you to hang the network easily and quickly.

autonomy

The Samsung Galaxy A50 seems particularly well armed in this respect thanks to the integration of a 4000 mAh battery. Note from the outset the lack of wireless charging that is still reserved at Samsung to more high-end products. Too bad, because this possibility is very practical in everyday life.

The supplied 15 W charger uses our 1:40 measurements to fully charge this large battery. An excellent time. It takes about 8 minutes to recharge to get an hour of autonomy.

Exactly, this one is very satisfactory since in front of our web tests, the Galaxy A50 resisted 11:52 before going out, and thus does better than the Galaxy S10. In practice, it is possible to do without recharge a day and a half or two days remaining very reasonable.

Verdict
Even if the competition can offer better, especially in terms of CPU power, the Samsung Galaxy A50 has no shortage of arguments. Its impeccable finish hides an excellent screen that allows you to enjoy a very successful home user interface. This smartphone mid-range has as a bonus a very satisfactory autonomy. Only his photo part can really disappoint in the end. Here is a model of homogeneity that demonstrates all the know-how of Samsung.

Rating: 4/5
