Breve Análise do Smartphone Samsung Galaxy A3 (2017)

Manuel Masiero (traduzido por Ricardo Soto), 04/11/2017

Atualização surpreendente. A mais recente reencarnação da Samsung de seu Galaxy A3 de gama média não apenas possui um design monobloco de vidro e metal, mas também melhorias significantes sob o capô, por exemplo, poder de processamento incrementado e desempenho melhorado da câmera. Será que isto é suficiente para mostrar a seus concorrentes quem é que manda aqui?

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 250 Hz92 % brightness setting

The display backlight flickers at 250 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 92 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 250 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 59 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 4352 (minimum: 43 - maximum: 142900) Hz was measured.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
6 ms ... rise ↗ and fall ↘ combined↗ 3 ms rise
↘ 3 ms fall
The screen shows very fast response rates in our tests and should be very well suited for fast-paced gaming.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 2 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (27.1 ms).
       Response Time 50% Grey to 80% Grey
9 ms ... rise ↗ and fall ↘ combined↗ 5 ms rise
↘ 4 ms fall
The screen shows fast response rates in our tests and should be suited for gaming.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 3 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (43.7 ms).

Há pouca ou nada de necessidade de uma atualização para aqueles que já possuem o Galaxy A3 (2016). No entanto, com a sua qualidade de construção similar, o modelo deste ano tem algumas vantagens.

Primeiro que nada, o Galaxy A3 (2017) agora é resistente à poeira e água (IP68). Além disso, ele possui uma porta USB Type-C, sua câmera não sobressai mais na parte traseira, parece ser significantemente mais sólido graças à ausência do marco de alumínio mencionado anteriormente, e roda um sistema operacional Android 6.0.1 mais recente.

Atualizar o processador para o Exynos 7870 mais veloz teve o efeito esperado sobre o desempenho geral. As melhorias da duração da bateria são mais importantes: devido à sua incrível eficiência energética, o Galaxy A3 (2017) é uma besta extremamente durável. Ambas as câmeras também foram melhoradas, e a mais recente reiteração se sai muito melhor em condições de baixa iluminação. A câmera frontal foi atualizada de 5 para 8 megapixels.

O Galaxy A3 (2017) está muito longe de reinventar a roda; porém, suas melhorias iterativas foram suaves e eficazes.

Apesar de seu formato manuseável e bastante prático de 4,7 polegadas, a parte traseira lisa pode causar um alvoroço com alguns usuários. A única coisa que você pode fazer é testar por si mesmo se  o telefone se sente escorregadio ou não. Nós não nos importamos com a traseira lisa. No entanto, não há maneira de disfarçar as deficiências do telefone: sem MHL, sem suporte para dual SIM, e sem estabilização ótica de imagem. Alguns usuários também podem notar o PWM-flickering em níveis de brilho abaixo dos 92%. Apesar destas limitações, o Galaxy A3 (2017) continua sendo um smartphone de gama média, sólido e respeitável com poucos motivos para reclamar.

There is little to no need for an upgrade for those who already own last year's Galaxy A3 (2016). With its similar build quality, this year's model does have a few advantages, though.

First of all the Galaxy A3 (2017) is now IP68 dust- and waterproof. In addition, it features a USB Type-C port, does not have its camera protruding from the back anymore, seems significantly sturdier thanks to the lack of aforementioned silver frame, and it's running a more recent Android 6.0.1 operating system.

Upgrading the processor to the faster Exynos 7870 did have the expected effect on overall performance. The battery life improvements are more important: due to its incredible power efficiency the Galaxy A3 (2017) is an extremely durable beast. Both cameras have been improved as well, and the latest reiteration fares much better under low-light conditions. The front-facing camera has been updated from 5 to 8 megapixels.

The Galaxy A3 (2017) is a far cry from reinventing the wheel; instead, its iterative improvements have been gentle and effective.

Despite its manageable and quite handy 4.7-inch form factor, the smooth back side may cause quite a stir with some users. The only thing you can really do is try for yourself whether or not the phone feels slippery. We for one did not mind the glassy back cover. Yet there is no way to sugarcoat the phone’s shortcomings: no MHL, no dual SIM-card support, and no optical image stabilization. Some users might also notice PWM-flickering at brightness levels below 92%. In spite of these limitations, the Galaxy A3 (2017) remains a very solid and respectable mid-range smartphone with little cause for complaint.
