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 242.7 Hz

The display backlight flickers at 242.7 Hz (Likely utilizing PWM) .

The frequency of 242.7 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8895 (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
4 ms ... rise ↗ and fall ↘ combined↗ 2 ms rise
↘ 2 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. » 1 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (25.9 ms).
       Response Time 50% Grey to 80% Grey
5.2 ms ... rise ↗ and fall ↘ combined↗ 2.4 ms rise
↘ 2.8 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 0.9 (minimum) to 636 (maximum) ms. » 2 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (41.4 ms).

The Galaxy A8 (2018) in review. Test device courtesy of allestechnick.

Com o Galaxy A8 (2018), a Samsung criou um smartphone de gama média bem equipado que oferece muito. O design parece e se sente premium é conta com certificação IP68. A tela Super AMOLED Infinity é visualmente impressionante, sendo bem ajustada e brilhante, enquanto também conta com uma alta resolução. A variante Dual-SIM é realmente Dual-SIM, contando com um slot dedicado para a expansão para cartões microSD, em vez de ter que escolher entre um segundo SIM ou um cartão microSD. Os fanáticos das selfies recebem uma câmera frontal dupla com bons óticos que deixa espaço para gimmicks enquanto ainda tira boas fotos, este último também se aplica para a câmera traseira de 16 MP.

Bom desempenho, porém, a um preço questionável. O Galaxy A8 (2018) cria concorrência desnecessária para si mesma, com o Galaxy S8 de gama alta mais veloz e melhor equipado, custando apenas cerca de €100 (~$123) a mais.

Apesar dos pontos positivos, os ambiciosos €499 (~$615) do preço recomendado, provavelmente fará que compradores potenciais desistam. Embora possa ser encontrado por menos, o Galaxy A8 (2018) permanece com o preço próximo ao do Galaxy S8, que traz melhores recursos e desempenho por apenas €100 (~$123) a mais, no momento desta análise. Também existem alternativas ao Galaxy A8 (2018) que são iguais de rápidas, como o ASUS ZenFone 4 ZE554KL ou o BQ Aquaris X Pro, que estão disponíveis por cerca de €450 e €350 (~$555 e $430) respectivamente.
