LG G7 Change Lock Screen: Wallpaper, Clock and Security

Updated 5 November 2026 · Standard formula, shown below

To change the LG G7 lock screen, open Settings and adjust the display, wallpaper, or screen-lock options you want. You can set a different lock-screen background, choose how the clock and notifications appear, and change the method used to unlock the phone; the exact options can vary with the installed Android software and carrier.

What you can change on the LG G7

“Change lock screen” can mean several different things. The G7’s lock screen is the screen shown before you unlock the phone, and its appearance and security are controlled by related but separate settings.

Wallpaper: changes the picture or image behind the lock-screen clock.
Clock and display: controls available clock styles and whether the screen can show information while it is off. The always-on display is related, but it is not the same screen as the lock screen.
Notifications: determines whether notifications and their details appear before unlocking.
Screen lock: sets or changes the PIN, pattern, password, or other supported unlock method.

Changing the wallpaper does not remove a PIN or pattern. Likewise, changing the unlock method does not automatically change the wallpaper.

Change the lock-screen wallpaper

On many LG G7 software versions, you can set the wallpaper through the Home screen settings or through the Settings app. Menu wording may differ slightly, so use the Settings search field if a label is not where expected.

Open Settings.
Tap Display, then look for Home screen or Wallpaper. On some versions, a wallpaper option is also available by touching and holding an empty area of the Home screen.
Choose a built-in image or a photo source, such as Gallery, if offered.
Preview the image and choose the lock-screen destination if the phone asks where to apply it. Select Lock screen rather than Home screen if you only want to change the background shown before unlocking.
Confirm the selection and press the power button to check the result.

If you see a choice for both Home screen and Lock screen, select only the one you intend to change. Some wallpaper pickers apply an image to both screens, while others let you set them separately. Cropping can also make a photo look different on the lock screen: position the subject so it is not hidden behind the clock or notifications.

Change the screen lock method

To change the PIN, pattern, or password that protects the phone, use the security settings rather than the wallpaper controls. The path is generally Settings > Lock screen & security > Select screen lock, though the wording and grouping can vary by software version.

Open Settings and find Lock screen & security or search Settings for screen lock.
Tap Select screen lock or the similarly named option.
Enter the current PIN, pattern, or password when requested. This confirms that you are authorized to change the lock.
Choose an available method, such as a pattern, PIN, or password, and follow the prompts to set it up.
Lock the phone and test the new method before relying on it.

Some security features depend on the selected screen lock. Removing a secure lock can disable features that require one, and saved biometric unlock options may need to be set up again after changing the screen lock. Availability depends on the phone’s software and configuration.

Adjust the clock and lock-screen notifications

For clock or notification changes, open Settings and check Display, Lock screen & security, and their related submenus. The G7 may offer settings for the lock-screen clock, screen timeout, or always-on display, but the available controls depend on the installed software. Always-on display shows limited information when the display is otherwise off; it does not replace the lock screen that appears when you wake the phone.

Notification controls are useful if you want alerts without showing message contents. Look for a lock-screen notification setting under the lock-screen or notification menus. Depending on the software, you may be able to show notifications, hide sensitive content, or prevent notifications from appearing. An app’s own notification settings can also affect what is displayed.

To keep private details from appearing before the phone is unlocked, choose a setting that hides sensitive content or turns off lock-screen notifications. This can reduce the convenience of reading alerts at a glance, so check the result with the screen locked.

If the setting is missing or does not work

Older phones can have different menu names after software updates, and carrier versions may arrange settings differently. Try these basic checks before assuming the feature is unavailable:

Search within Settings for terms such as “wallpaper,” “lock screen,” or “notifications.”
Confirm that the wallpaper picker applied the image to the lock screen, not just the Home screen.
Restart the phone if a change appears not to take effect, then lock and wake it again.
Check whether a downloaded theme or launcher is changing the appearance of the Home screen. A launcher may affect the Home screen without controlling Android’s secure lock screen.
If you cannot remember the existing screen-lock credential, do not keep guessing. Use LG or Google’s current official support guidance for the phone and account; recovery options can depend on the device’s state and may erase data.

A common misconception is that changing or removing the lock-screen wallpaper will reset the PIN. It will not. Wallpaper is a visual setting; the screen lock is a security setting. Keep the two tasks separate, and make sure you know the current credential before attempting to replace it.

Frequently Asked Questions

How do I change the LG G7 lock-screen wallpaper?
Open Settings and look under Display, Home screen, or Wallpaper. Choose an image and select Lock screen as the destination when that option is offered.

Can I use a photo from my Gallery?
Usually, the wallpaper picker offers a Gallery or photo option. Choose the photo, adjust its crop, and apply it to the lock screen if the phone provides separate destinations.

How do I change my LG G7 PIN or pattern?
Open Settings, find Lock screen & security, and select the screen-lock option. You will generally need to enter the current credential before setting a new one.

Can I hide message previews on the lock screen?
Check the lock-screen notification settings for an option to hide sensitive content or turn off lock-screen notifications. The exact choices depend on the installed software and app settings.

Why does my new wallpaper only appear on the Home screen?
The wallpaper may have been assigned only to the Home screen. Set it again and choose Lock screen, or a combined option, if the wallpaper picker offers one.

Will changing the lock screen erase my data?
Changing wallpaper, clock, or notification settings does not normally erase data. A forgotten credential or reset procedure is a separate issue and may have different consequences; consult official support before taking recovery steps.
