Lenovo k3 note was good phone till 2015 under 10k but it performance is average. Back camera does not give feel about 13 mp. It look like 8 mp. Front camera is good. SAR value omg. Very high.
Display is nice with higher ppi. Gaming performance is average.it has 2 gb ram. Still I face same lag and hang while playing heavy games and multitasking. Sound output is good.battery is good last upto 1 day for normal usage.
For continuous heavy usage it last upto 4 to 5 hrs but now day it become old.already k4 not was released which is also not as per expected.
