S Pen airview doesnt work

view story

http://forums.androidcentral.com – Hey, I bought note 2 few days ago and I have noticed that S Pen airview icon (small blue circle) does not work on lower right hand corner of my screen. When I hover the pen over that part of screen that blue circle does not appear at all but every thing else works fine (display, touch) is this a manufacture fault? Is there anyway to fix this? or should I take it back to the shop? Thanks (HowTos)
