Well I just took a new backup of everything on the device without the apps and device settings. so would you want me to format the device again and just restore the data and check. Also this does not happen constantly at times its on a loop but otherwise its just goes on usually when I am on call or playing music. And the 1st handset was purchased like a week after it was released here in India, the current device is new box replacement which I received the next day.
