S5 Air Gestures on other MTK based phones

[matrx10503]

I have a iDroid iKon z5.
It has a quad core MTK6582 processor.
I have rooted it using the custom CWM recovery method.
It is running Android 4.4.4

My question is, most of the S5 clones have the air gestures feature that works. You can swipe the home screen page and swipe down the notifications bar with air gestures.
I have an app called Air Swiper that lets me unlock and turn the phone off with gestures and a few more.

Is this a launcher enabled feature or how does the S5 clones have this feature. System tweak?
Is there anyway to download a stock rom of s5 clone, and try to find and take that specific feature?? Or is this because of the kernel it uses?

Wow.....This phone already has it.
Its called "Intelligent somatosensory"
But I installed Nova launcher from the start and never used the stock home launcher.
But it doesn't seem to work after I choose Nova as my launcher.
