I just bought lenovo k3 note one month before.its touch is so bad .I hv gone to service centre they restored it and gave back to me .no solution was done.I hv wasted my money.and one more prblm after off mode "vibrate on touch " in setting .there is always touch at the time of dialing or chatting .no option is there to off it in k3 note .I hv talked in service centre also about this prblm they replied sir its headset model problem.no solution
