Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 250 Hz |  | |
The display backlight flickers at 250 Hz (worst case, e.g., utilizing PWM) . 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: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8715 (minimum: 5 - maximum: 343500) Hz was measured. | |||

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.
