Hii friends, I am using this from 2 month initialy it works good there is no any lagging or anythig but now its started lagging. And 17k phone and its started lagging in two month very bad. 5.5 invh display is also not upto the mark beacouse its not smooth you feel it clearly when you use it. Sound quality is also not good. Storage is good 32gb is anough for me and 3GB Ram is also good but even in this phone 3gb rm and then also laggging so bad. Battery backup is good no dought about the battery. Camera is also not good for this phone because 17k phone and it give very low quality of picture.design was good.
