Running on MM, chroma noise on snapchat

So ya, just looking for a way to enable the chroma noise reduction, seems they turn it off or something on MM, btw I kinda like in the daylight but when I'm in the club there is too much chroma noise, btw I'm fine with the luminance noize, I just want to get ridd of thar chroma noise thing. On LL the photos were OK but still LG oversharp everything and I dont like it.
I'm also looking for ways to improve the camera.....idk, I had the G2 and I used to use XCam.
