Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 240.4 Hz | ≤ 99 % brightness setting |  |
The display backlight flickers at 240.4 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 240.4 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 8774 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Contra
O Samsung Galaxy A7 (2018) se destaca em nosso teste com seu excelente painel Super AMOLED que pode se tornar muito brilhante, possui uma reprodução de cores extremamente precisa e ângulos de visão estáveis. Além disso, tem bons contraste graças ao valor de preto perfeito típico das telas OLED. Tudo somado, esta é uma tela que não tem igual nesta faixa de preço.
Estamos menos impressionados com o processador de gama média da Samsung. O Exynos 7885 mostra várias fraquezas ao lidar com cargas de trabalho diárias durante o nosso teste. O desempenho do sistema do Samsung SoC não consegue acompanhar a concorrência da Qualcomm. O Honor 8X equipado com o novo HiSilicon Kirin 710 também pode oferecer um desempenho mais consistente no dia a dia.
A figura de proa do Galaxy A7 (2018) é sua câmera tripla, que oferece grande versatilidade e qualidade fotográfica decente. O ângulo ultra-wide e a função Live Focus oferecem aos usuários opções interessantes, embora a última função possa ser um pouco decepcionante às vezes.
Como com o Honor 8X, ficamos nos perguntando por que a Samsung decidiu equipar seu modelo 2018 com um padrão microUSB antigo. Isso não faz sentido, especialmente considerando que o Galaxy A5 de 2017 já estava equipado com uma porta USB Type-C.
Os amantes das telas não chegarão perto do Samsung Galaxy A7 (2018), se estão procurando por um dispositivo adequado no segmento de preços de gama média.
Há muitas alternativas interessantes nesse segmento de gama média. Por exemplo, o poderoso Pocophone F1 ou o significantemente mais econômico campeão do preço-desempenho Xiaomi Mi A2. Caso o preço do Samsung Galaxy A7 (2018) caia um pouco, sua ótima tela e opções de câmera grande angular ainda fazem dele uma alternativa interessante.
