Generally, mobile phone lock screen wallpaper is called mobile phone screensaver. In order to prevent the mobile phone from displaying the same screen for a long time due to unattended operation, the screen display is aging and the service life is shortened.
Add a new wallpaper for the lock screen or home screen:
In the Settings app, tap Wallpaper.
Click Add New Wallpaper.
Tap Photos, People, or Random Photos to choose your own photos. You can also choose wallpaper from weather and astronomy, emoticons, choices or colors.
If necessary, you can further customize your wallpaper. Then click "Finish".
Change the wallpaper from the lock screen:
Please make sure that you have set the face ID on the iPhone before. To change the wallpaper from the screen locked state, face ID must be able to clearly detect your eyes and the area around your eyes.
On the lock screen, press and hold the lock screen to open the wallpaper library.
In the lock screen wallpaper option, you can also click the focus button to associate the focus mode with a specific wallpaper, customize an existing wallpaper, or swipe up and click the wallpaper to delete it.
If you can't change the lock screen with your face ID, press and hold the lock screen until the Customize button appears. If the Customize button does not appear, press and hold the lock screen again, and then enter the password.
Customize and lock screen wallpaper with filters, widgets, and styles:
In the Settings app, tap Wallpaper.
Under the lock screen preview, tap Customize.
Tap Customize Current Wallpaper or Add New Wallpaper, and then select a wallpaper.
Make your own customization, and then click Finish on the wallpaper.
To choose a font and text color, tap the time.
To add or remove widgets (such as calendar, clock, weather, fitness or reminders), tap the box above or below the time.
To apply a photo style, such as black and white, two-tone or washed color, please swipe left or right.
To crop and move photos, hold and drag them with two fingers.
To select wallpaper options, click the More button. View Zoom can move the wallpaper when you tilt the screen. "Depth of field effect" can enhance the layering of photos and highlight the subject.
IOS 16 and later versions provide the function of customizing screen-locked wallpaper.
Rotate multiple photos as wallpaper to lock the screen:
In the Settings app, tap Wallpaper.
Click Add New Wallpaper.
Select Random Photos from the top line of the option.
On the random photo display screen, set the frequency (when clicked, when awakened, every hour or every day). Then select a group of photos, which will be randomly displayed when using the iPhone during the day.
