Screensaver Clock

[Daveleh]

Hi, i have just upgraded from a nokia 3 to a galaxy a21s. On the nokia i could set the screensaver to display a moving clock when the phone was connected to a charger.  I have tried to do this on the galaxy but there's only options i can find for screensavers are for photos.  Is there away ican at this up without installing an external clock app please?

I have the same issue. You just can't see anything when it's charging
