Hi I am used for lenovo a6000 last 1 year ago. I have purchased by online. Its battary back up is very poor. But this smart phone is enable 4g LTE its also used for reliance jio. Both Camera quality is very good. And you have used to continuous internet its very heating. Not problem in network. And we are connected in charger also we use to net phone is very heating. 1 reason is slow in phone Ram is 1 Gb I think is also slow in working. Spaker is good.and the style is good and slim piece.The most negative point is hang . So this reason I have many time formet this phone. I have dislike this phone.
