Lenovo Mobile — Lenovo K3 Note Mobile Hang, Touch & Heat Issue

Since 1 Month ago I purchased Lenovo K3 Note from www.Flipkart.com, Since then there is no issue in mobile all well. but since 10-15 days I found touch problem while I'm pressing touchpad and I have to touch thrice and four times than after the proper key will choose as touch. One more thing is that my phone will become hot after some time around 2-3 mins, I can't hold it in my hand. Need help ASAP... I am waiting for your reply. Name : Niraj Beladiya Mo.
