Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 250 Hz | ≤ 99 % brightness setting |  |
The display backlight flickers at 250 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 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 8774 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Com o seu impressionante vidro traseiro, a aparência externa do Samsung Galaxy A9 (2018) é um verdadeiro destaque. Sua qualidade de fabricação também é muito boa, embora nosso dispositivo de teste, em particular, tenha algumas pequenas falhas. Como o fabricante coreano parece estar fazendo mais frequentemente, a Samsung escolheu equipar seu mais novo membro da família na série Galaxy A com um painel OLED muito bom. Em termos de reprodução de cores e brilho, o Galaxy A9 (2018) compete no topo da sua liga. No entanto, o mesmo não pode ser dito do desempenho do sistema no padrão de fábrica. Devido às suas animações pré-instaladas, o smartphone de gama média se sente um pouco lento, o único remédio aqui é se livrar deles no menu de opções do desenvolvedor.
Devido às suas animações pré-instaladas, o smartphone de gama média se sente um pouco lento, o único remédio aqui é para se livrar deles no menu de opções do desenvolvedor. Claro, nem todos os smartphones de gama alta precisam ser comparados com o Xiaomi Pocophone F1, mas o fabricante chinês conseguiu equipar seu dispositivo de gama média com o atual chip de gama alta da Qualcomm. Como resultado, com um preço de varejo recomendado de 600 Euros (~$680), a Samsung poderia ter pelo menos equipado o Galaxy A9 (2018) com o chip de maior desempenho do ano passado - considerando que a empresa optou um SoC de 2017 em primeiro lugar.
O Samsung Galaxy A9 (2018) é um bom e muito atraente smartphone de gama média - mas ao preço atual de cerca de 480 Euros (~$550; versão internacional ~$525), existem alternativas melhores no mercado.
O ponto de venda exclusivo do Samsung Galaxy A9 (2018) - a câmera quádrupla na parte de trás - pode ser usada para uma ampla gama de aplicações, graças às suas quatro lentes diferentes. Combina todas as vantagens habituais das multi-câmaras (efeito bokeh, ultra grande angular, zoom ótico) num único dispositivo. No entanto, nenhuma conclusão deve ser tirada com base no preço de varejo recomendado quando se trata da qualidade da câmera principal. A câmera é muito rápida, mas em termos de qualidade de imagem, ela não tem desempenho melhor do que a média de um smartphone de gama média.
