Why is my selfie video camera not recording clear action movements?

ZTE Z981 Selfie video camera isn't recording clear action movements anymore.  Only when I record through the back or rear camera.  Wondering if the selfie video isn't working anymore, new software update needed? or really I cannot figure it out.  Selfie camera works fine taking photos, its only the movements the camera is slow to follow the action, the videos looks like you're in a rave w/ your glowsticks

Did you recently make any changes or install any app before that started happening?
