- A tela táctil registra entradas incorretamente com frequência

In review: Lenovo Tab 2 A8-50. Test model provided by Lenovo US

O Tab 2 A8 é um tablet respeitável pelo preço demandado de $129. O brilho da tela e a duração da bateria estão acima da média e a qualidade do som é bastante boa considerando o seu mercado alvo. Infelizmente, não muito mais do aparelho pode ser elogiado. Não podemos evitar sentir que o seu 1 GB de RAM e a resolução de 800p da tela são pouco para um tablet em 2015. Também é um pouco mais pesado que outros modelos de 8-polegadas e sua tela táctil registra entradas incorretamente.

Recomendamos o Lenovo Tab S8 em vez do Tab 2 A8 para usuários à procura de um tablet de 8-polegadas. O Tab S8 é mais leve, fino e brilhante, e melhor que o Tab 2 A8 e é vendido atualmente por $169. Os $40 extras podem ser melhor gastos em outras coisas.

Recomendamos o Lenovo Tab S8 en vez do Tab 2 A8 para usuários à procura de um tablet de 8-polegadas.
