How to remove sleep screen from Galaxy family? I have a Note2 and there is this annoying screen that turns my screen on just to show some purple bubbles, the clock and number of calls and messages. After a feel seconds it turns off again. 

I understand that it consumes certain battery but I don't use it. I searched everywhere but couldn't find any tip on how to remove it. 

Anyone could help me? 
Thanks
This is Samsung's "Quick Glance" feature, which triggers when a hand is waved over your sleeping phone.

You can turn it off in Settings -> My Device -> Motions and Gestures -> Air Gesture -> Quick Glance.
