Why doesn't xs astronomy show green dots?

Xs performance is low, and astronomy does not show green dots. Apple xs is a smart phone owned by Apple. The reason why 16 Earth Green Dot is not supported is that its performance is low and it cannot be run with wallpaper. Apple has become the world's largest company by market value for three years in a row, and a small green dot switch can tell the positioning control. If you want to close the little green dot, in the positioning, find astronomy, and just close the positioning.
