Thumbs up [Q] Weird low light frame rate fix

I just found out by chance, thought at first that kitkat update fixed the issue but was suprised becasue i remembered that i checked instantly after updating and it was not fixed, anyways if you turn camera on set it to 60 fps, record a video(just a sec is all it needs) and then put it back to 30 fps the and push record lowlight framerate fixes it self and the video is smooth but dark like it should be. what is going on? iŽll take this over nothing anyday thoug.
