Screen Saver Clock Style auf Android
Android ships with a built-in screen saver that can show a clock, colored shapes, or your photos while the device charges or sits idle on a dock. The clock style is not exposed on the main Display page. It sits one level deeper, inside the screen saver customization panel.
To reach it, tap on Settings ➔ tap on Display ➔ tap on Screen saver. From there, tap on Select Clock, Colors or Photos and choose the Clock option. Tap on Customize to open the style picker and set the Clock style between analog and digital.
This setting only affects the screen saver, not the lock screen clock or the always-on display, which are configured separately. If the screen saver never triggers at all, check whether it is set to activate while charging, while docked, or both, since an inactive trigger condition will keep the clock from showing regardless of the style you pick.
Switching styles does not change the time zone, format, or size of the clock. Those adjustments, where available, are usually found in the same Customize panel right next to the style option.
