Metal smartphones Samsung GALAXY A3 and A5: test screens – Mail.Ru


     

     


     

Smartphones Samsung GALAXY A3 and A5 were officially presented recently (read about these updates), but it got us to the test. Recall that the model is interesting metal housing (including the back cover). This is the first time at Samsung. Koreans are positioning A3 and A5 as a premium solution with expensive materials. Prices are relevant. In this case the desired metal users were not exactly what they wanted, because the metal is painted here (as a side and rear), because of what looks like plastic. But it’s a matter of taste, and we conduct tests of objective indicators. Full review coming soon on the site, but for now let’s look at the screens of these models. Traditionally Hi-Tech.Mail.Ru very detailed approach to this element in smartphones.

 

Samsung GALAXY A3 and A5 will appear in Russia in December, the price will be 15-20 thousand. Rubles for a younger model and 20-25 thousand. Rubles for older (this plug is due to fluctuations of the ruble, and judging by recent events, most likely, the final cost will be closer to the upper limit). Both smartphones use Super AMOLED, which is traditional for Samsung. But the resolution of this class of unexpectedly low: 960×540 pixels at A3 (diagonal 4.5 “) and 1280×720 pixels at A5 (diagonal 5″). As a result, we get 245 ppi and 294 ppi, respectively.



 

At lower resolutions more visible PenTile, he is present here.


 

Judging by the numbers, it’s not a lot, many analogues have already Full HD with higher pixel density and are thus cheaper. Price Samsung does not seem justified. However, we must take into account the “psychological barrier” around 300 ppi, after which the race for the pixel density abruptly loses its meaning, so that in a couple of A3 and A5 second model looks more or less justified, can not be said about the very low resolution first. At lower resolutions more visible PenTile, he is present here.

obscene screen Samsung GALAXY A5 looks good, but the density of points lower than in the old iPhone (namely the Samsung consider their main competitors for their premium A-series). But the image on the screen younger GALAXY A3 really loose, then impressions are completely consistent with the figures. Small parts and fonts are most distorted it to A3. Comparing both the screen with Samsung GALAXY S5, equipped with Full HD-display with a resolution of 1920×1080 (5.1 inches, 432 ppi), a noticeable difference on the definition in favor of the latter. It is a pity that Samsung decided to sacrifice resolution in metal models.

Compare further and see that antiglare novelties A3 and A5 has a high efficiency, while GALAXY S5 few surrenders to light under angle. The same applies to the angles. In principle, these are all very close in this way, and the difference regards microscopic nuances. It will be visible on the white pattern (eg, web pages) at an angle where the S5 is brighter, and the A5 and A3 dull.



 

On the white pattern (eg, web pages) at an angle of Samsung GALAXY A3 and A5 slightly fainter than GALAXY S5.


 

In this case, the maximum brightness directly in manual mode at the screen Samsung GALAXY A3 reached 330 cd / m 2 , at GALAXY A5 identical results. We are talking about a white fill the entire screen – as usual with AMOLED, with a decrease in the area of ​​white brightness increases slightly. About contrast long talk is not necessary – in AMOLED conditionally zero black, so that the contrast depends only on the ambient lighting. In the dark, we get absolute black, although in light picture pleases deep and pure colors. This is the traditional trump AMOLED.

The average range of displays from the A3 and A5 is very similar: 2.26 and 2.3. The logic is the same settings, all halftones and fine details are visible.

The color rendition AMOLED display on the Samsung smartphone is completely dependent on the selected mode. Four options are available:

  • Adaptive display
  •  

  • Film AMOLED
  •  

  • Photo AMOLED
  •  

  • Basic
  •  

Setting “Adaptive Display” defines color based on the running application. In the photo gallery are the natural colors, and in games – more saturated.

Mode “Film AMOLED» is a setting in the spirit of earlier AMOLED – it coolish hue image and a very rich, bright, even a “flashy” colors.

Mode “Photo AMOLED» simulates a wide color gamut of Adobe RGB, while maintaining a neutral tint of the image. Now that’s better. A good compromise between vivid colors and adequate image.

Finally, the “Basic” mode – the most optimal. It will dwell.

The average color temperature close to 6500K.

The color balance in case A5 set up well, and at A3 – perfectly. Average Delta E error in both cases is low – 1,31 and 0,97.

The color gamut beyond the scope of the standard sRGB – particularly, it concerns green. Equally important is the situation “inside” the triangle.

Here, all is well. Intermediate gradations are close enough to the standards by the shade.

This is confirmed by 24 templates ColorChecker: Average Delta E color error here is 2.75 (for A3) and 2.88 (for A5) units. It turns out that despite the odd color gamut, natural colors are transmitted with high precision.

In summary, our test, we can say that the AMOLED-display Samsung GALAXY A3 and A5 have decent brightness characteristics, color rendering them adjusted over a wide range for different tastes, but it is traditional for AMOLED technology nuances. The main gripe concerns the resolution – yet we have become accustomed to on smartphones in this price category set clearer displays. This particularly applies to the screen with the index A3 245 ppi, which is strongly not up to the desired turn 300 ppi, and its price is twice higher than that of many competitors with HD and even Full HD screens. Together with the effect of PenTile (loose fonts, pixelation) does, for example, browsing uncomfortable. also bring disadvantages worth very large screen frame, typical of low-end models, but not the high-priced vehicles. Why not reduce the scope of the screen is not very clear. It would be logical to see these parameters in models with a price at least a half times lower, and now the margin for the metal of the Samsung too great.

 

Alternatives. When we say that the price of the new Samsung smartphones unjustified, we compare the proposals of other companies in the same price class, which can now be found in retail. From Full HD models Samsung GALAXY A3 competes with Huawei Ascend P7 and a number of other models up to 20 thousand. Rubles, in particular with the Chinese flagship of Xiaomi and other brands, such as, Mi4 now worth just the ones 15-20 thousand. rubles (depending on the greed of the seller). Samsung GALAXY A5 opposes Quad HD flagships (Lenovo Vibe Z2 Pro, LG G3 and several others up to 25 thousand. Rubles).

 

You bet on the premium and image, for which the Koreans want to get more money, but everything is complicated by the competition with last year’s champions, in the first place with all-metal HTC One (M7) Dual Sim, recommended price which now amounts to 19 990 rubles, and accordingly he is a strong opponent of both innovations Samsung.

 

What do you think about pricing on Samsung’s first fully metal smartphones this brand? Are you ready to buy some of the models for such money or prefer to competitors? Speak with us in the comments.
