Screen Flickering / PWM (Pulse-Width Modulation)
Screen flickering / PWM detected | 2358 Hz | ≤ 15 % brightness setting | |
The display backlight flickers at 2358 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 15 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 2358 Hz is quite high, so most users sensitive to PWM should not notice any flickering. 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. |

O BlackBerry KEY2 é a representação do móvel da BlackBerry Mobile, ou melhor, da TCL Communication, de lançar uma versão mais barata de seu smartphone carro-chefe. Afinal, nem todo mundo pode ou quer pagar mais de $600 para um smartphone. Em suma, a TCL criou uma versão simplificada do KEY2 sem sacrificar em áreas-chave. A diferença de desempenho entre o KEY2 LE e o KEY2 é dificilmente perceptível, a menos que ambos sejam pressionados, enquanto ambos os dispositivos têm duração de bateria comparável, apesar de o primeiro ter uma bateria menor de 500 mAh. Além disso, suspeitamos que a câmera mais fraca do KEY2 LE não afetará os clientes corporativos. O único compromisso prático é a falta de gestos de toque do teclado, que se mostrou útil durante o nosso tempo com o KEY2.
Reduzido, mas nos lugares corretos. O BlackBerry KEY2 LE é um smartphone empresarial decente com um teclado físico que retém a maioria dos melhores recursos do KEY2.
No entanto, é frustrante que nosso dispositivo de teste tenha correções de segurança do Android de três meses atrás quando o dispositivo é comercializado como sendo mais seguro do que outros smartphones Android. O TCL também inclui muitos aplicativos pré-instalados, o que pode afastar algumas pessoas que preferem uma experiência Android mais limpa. A tela também está abaixo do esperado, mas a precisão do GPS, a qualidade de construção e o desempenho são impressionantes para um smartphone de menos de $500.
No geral, recomendamos o KEY2 LE para quem deseja um smartphone com teclado físico, mas deseja manter os custos baixos. O dispositivo tem melhor relação custo-benefício do que seu irmão mais caro, mas o KEY2 é o melhor dos dois por apenas $150 a mais no momento em que este artigo foi escrito.
