I purchased lenovo k3 note 2 years ago . It has a very good camera both( front and back) . It has nice speaker with dolby atmos which enhances sound effect .
But there is no earphones in box, when I purchased this phone, This is a disadvantage.
The major issue for this phone is that it gets heated up quickly since it has mediatek processor and all the applications start operating poorly.
The battery capacity is too bad, though it has 2900mAH battery capacity but the phone battery drains up very quickly, which is disadvantage buying lenovo k3 note . The touch screen is also not worth .
I have to reset phone monthly so thatig works properly.
Overall its a phone with almost equal advantages and disadvantages
