My first lenovo mobile let me down with the worst performance. After a long while, I bought this Lenovo k8 note which is also let me down again.
1) deca core processor, but still lags, not fast enough.
2) getting heated up like iron box while charging. I think one can iron their clothes with this phone.
3) lenovo still a plenty of work to do to make their mobile phones work better. Even, their chinese counter parts - honor & Xiaomi are doing great from their failures/set backs. Lenovo yet to learn that. This mobile has got very good specifications, but its software is not optimised for better parfomans. As usual, lenovo lost its basics.
4) 4000mAH battery, but it doesnt last for a day after the update.
There are many issues with this Lenovo mobile. So, as others said, DONT BUY IT BY SEEING THE SPECIFICATION. If you do so, you will be one among us to worry about your decision about buying this mobile.
