Screen Saver Content Settings auf OnePlus
The OnePlus screen saver defaults to a digital clock, and many owners never notice the Colors or Photos options because they sit behind a separate content picker.
Open Settings ➔ Display ➔ Screen saver ➔ Current screen saver to reach that picker. Choosing Clock, Colors or Photos here decides what the screen saver actually shows.
Selecting Clock unlocks a second settings screen. Tap Settings again, then Style to switch between Analog and Digital, and toggle Night mode to dim the display automatically after dark.
Photos and Colors skip the style step since they have no analog or digital variant. If the screen saver still shows the old content after a change, reopen Current screen saver to confirm the new selection actually saved.
