Oneplus 2 recording low FPS in low and artificial light conditions Oxygen 2.1.1

I have reverted back to stock OS since I prefer how the camera pictures result there. However, I have noticed that the video recording in the stock camera has a disappointing low FPS in lowlight and artificial light when recording. But when I use other camera apps such as google camera or cameranext, the fps recording is decent but the exposure is very low, and the video output has a narrow field of view.

Is there a fix for this problem for the stock OS? Or is this a software problem in Oneplus' end? :D
