Address:

Myself shivaraj hiremath purchased lenovo k3 note dated 01/10/2015
Now the problem is mobile is getting more heat than the normal limit within usage of few minutes, some times it reaches 55 to 60 degree celsius too.
It starts heating within few minutes o[censored]sage which is intolerable to human body.At that time im unable to connect the phone calls and cellular data properly even at 3g network it starts connecting with 2g.

Mean while i was given for service at lenovo service center hubli i don, t know what they did but still its giving the same trouble.
