La Lenovo Tab 4 8 es una tableta asequible que no destaca. Su diseño es bastante restringido y conservador, la carcasa es susceptible a las fuerzas de torsión y la presión, y la resolución de la cámara, la calidad de la imagen, el rendimiento y la conectividad son típicos de su clase.
En otras palabras: la tableta de Lenovo no es especial de ninguna manera pero al mismo tiempo es sólida de muchas maneras. Los ángulos de visión de la pantalla brillante son excelentes, el GPS es preciso y el dispositivo no se calienta mucho bajo carga. Particularmente dignos de mención son sus altavoces frontales, su versión pura de Android, y su batería grande a pesar de que Lenovo no ha podido exprimir el aguante de la batería extra. Se puede hacer a prueba de niños con accesorios opcionales, y nos gustaría destacar de nuevo el hecho de que a diferencia de otros fabricantes, Lenovo ha gastado tiempo, dinero y energía pensando en cómo mejorar una tableta barata con accesorios opcionales.
La Lenovo Tab 4 8 es una tableta de 8" sólida sin parafernalia pero con un rendimiento general sólido.
En general, las tabletas como la serie Yoga de Lenovo son mucho más innovadoras que la Tab 4 8. Sin embargo, esta última ofrece un rendimiento sólido sin defectos reales a un precio decente.
