Verdict - good-quality Lenovo Tab M8
O Lenovo Tab M8 HD se apresentou como um tablet simples para navegar e assistir vídeos ocasionais. Sua duração da bateria é particularmente impressionante, assim como o design fino e o acabamento de alta qualidade. Nossa unidade de teste super com facilidade o Amazon Fire HD 8 nestas áreas. Seu desempenho é um pouco melhor do que o do tablet da Amazon também, embora o Tab M8 HD ainda não consiga acompanhar seus outros concorrentes.
O Tab M8 HD da Lenovo é uma boa alternativa no segmento de tablets acessíveis.
No entanto, não espere muito das câmeras do tablet. Seu armazenamento interno limitado também é um pouco decepcionante, embora esse problema possa ser resolvido formatando o cartão microSD como armazenamento interno. As opiniões podem diferir sobre a utilidade da ampla gama de software que a Lenovo incluiu neste tablet. O modo infantil definitivamente dá uma boa impressão e a gestão do tablet pode economizar tempo aos usuários menos experientes que procurarem no menu de configurações do Android. Usuários cujas expectativas não são particularmente altas ficarão muito satisfeitos com o Tab M8 HD.
