I used Lenovo k3 note for 4 months now I will share my real experience with you all. before buying this phone once check my review may it will help to choose the product.
The UI of this phone is good, supporting attractive themes really make special to use.
Decent battery life I charge only once per a day. The things you have to know before buying is This phone don't support any fast charge option.
It took lot of time to charge 100% apart of that I didn't find anything con in this phone but sometimes it freezing while playing HD games as you know this phone heats much when you are doing multitasking.
The final report is this is good and affordable price tagged phone in the year of 2016 but there are a lot of replacing mobiles came to android market now so once compare before choosing this.
