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 257.7 Hz

The display backlight flickers at 257.7 Hz (worst case, e.g., utilizing PWM) .

The frequency of 257.7 Hz is relatively high, so most users sensitive to PWM should not notice any flickering. However, there are reports that some users are still sensitive to PWM at 500 Hz and above, so be aware.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8705 (minimum: 5 - maximum: 343500) 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 0.1 (minimum) to 240 (maximum) ms. » 12 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (20.9 ms).
       Response Time 50% Grey to 80% Grey
4.8 ms ... rise ↗ and fall ↘ combined↗ 2.8 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 0.165 (minimum) to 636 (maximum) ms. » 13 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (32.8 ms).

In review: Samsung Galaxy J7 (2017) Duos SM-J730F

O Samsung Galaxy J7 (2017) é um smartphone bem feito. No entanto, não consegue dominar seus concorrentes tanto quanto o Galaxy J5. Isso se torna muito aparente em termos de duração da bateria. No entanto, isto é reclamar em um nível muito alto, dado que ainda é muito bom. Apesar da bateria maior, infelizmente é pior do que o J7 do ano passado. A Samsung pode melhorar isso com uma atualização.

O Samsung Galaxy J7 (2017) não melhorou em todos os aspectos. No entanto, é um ótimo smartphone.

O Galaxy J7 (2017) pode brilhar com a sua ótima tela Super-AMOLED, que é finalmente controlada por um sensor de luz ambiente - o que estava atrasado há muito tempo. Além disso, agora oferece resolução Full HD. Infelizmente, a Samsung não equipa o telefone com um SoC ligeiramente mais poderoso para lidar com a maior densidade de pixels. Isso é notório no desempenho fraco dos jogos, mas também pode ser um motivo para durações da bateria mais curtas. As câmeras não são modelos de referência, mas produzem bons resultados se o ambiente for suficientemente iluminado. O módulo Wi-Fi não suporta apenas todos os padrões atuais, mas também oferece boas taxas de transferência. O armazenamento interno de 16 GB também é bastante padrão. No entanto, a capacidade de armazenamento pode ser expandida com um microSD sem renunciar ao recurso dual SIM.

O que resta é um smartphone visualmente melhorado. No entanto, sua bateria agora é removível. Em troca, ele vem com um sensor de digitai e 3 GB de RAM. Para alguns, pode valer a penas adquirir o modelo do ano passado.
