Hi RandomUserThatExists,
Do you have specific photos selected for the Lock Screen wallpaper? If so, try selecting more photos. This will guide you:
"If you choose a photo for your Lock Screen, you can reposition the photo, change the photo style, and more.
- Reposition your photo: To reposition your selected image, pinch open to zoom in on it, drag the image with two fingers to move it, then pinch closed to zoom out.
- Change the photo style: Swipe left or right to try different photo styles with complementary color filters and fonts.
- Create a multilayered effect: If you have a photo that supports layering—like an image with people, pets, or the sky—tap
at the bottom right, then choose Depth Effect. - Note: The multilayered effect is available on supported models. Layering may not be available if the subject is too high, too low, or obscures too much of the clock.
- Set the shuffle frequency: If you choose Photo Shuffle, you can preview the photos by tapping
, and set the shuffle frequency by tapping
, then selecting an option below Shuffle Frequency."

Take care.
