Lenovo k3 note is a budget smartphone which has maximum selling price of rupees 9999 but you may get it for as minimum as 8500 through flipkart during schemes. It has got a full HD screen that is 1080p resolution it also supports 4g LTE, consists 2 GB of ram these certainly are the pros now following are the cons
1.) Certainly if you talk a lot then it should not be your cup of tea as it has REAL High SAR rating( specific absorption rate)= 1.59( HEAD) 06.88( BODY) this has a lethal effect.
2.) it doesnt contain gorilla glass so you will be required to compromise with the tempered glass.
3.) It doesnt come with a fast charger. Output current is 1.5 ampere which is pretty low.
4.) built quality is average.
5.) gets warmer with average use.
