Screen Flickering / PWM (Pulse-Width Modulation)
ℹ
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 not detected |  | ||
In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8743 (minimum: 5 - maximum: 343500) Hz was measured. | |||
Display Response Times
ℹ
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 | ||
|---|---|---|

| The screen shows relatively slow response rates in our tests and may be too slow for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 68 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21 ms). | ||

In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 64 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.9 ms). | ||

Pro
+ Qualidade decente
+ Carcaça rígida e sólida
+ Bateria substituível pelo usuário
+ S Pen incluída
+ Suporte para cartões MicroSD de até 256 GB
+ Tela brilhante
+ Permanece frio
Contra
- Duração da bateria medíocre
- Tela de baixa resolução
- Lenta memória de armazenamento
Sem dúvida: O Galaxy Tab Active 2 é um poli funcional muito sólido. O sistema operacional é fluente e o dispositivo deve ser capaz de lidar com as tarefas diárias com facilidade. O armazenamento interno é bastante limitado e, embora, em teoria, o sistema não exija mais espaço de armazenamento, um cartão MicroSD adicional se tornará uma necessidade mais cedo e não mais tarde. Pelo menos suporta cartões MicroSD de até 256 GB de capacidade.
Debaixo da sua pele endurecida e grossa está um tablet de gama média. Está adequadamente equipado, e os potenciais clientes provavelmente irão comprá-lo de qualquer forma devido à falta de concorrentes reforçados para exteriores.
Resta ver se o Galaxy Tab Active 2 que acabará por ser útil em uma oficina, garagem ou um site de construção, ou não. É certamente mais sólido e mais robusto que a maioria dos seus concorrentes, e pode se tornar um companheiro muito seguro em caminhadas e no campo. A tela permanece utilizável com luvas e a S pen incluída permite uma entrada de toque muito precisa.
