Why doesn't the camera function of the mobile phone have the function of fast and slow playback?

The camera that comes with the iphone can shoot, and the fast one is called time-lapse photography, and the professional one is called upgrade photography. Slow play is called slow motion, and the major is called degenerate photography.

Android phone has been useless for a long time. I don't know if it has, even if it doesn't, there will be a photography APP to provide this function.
