How to Secure and Customize Your Samsung Lock Screen

Change your Samsung lock method, wallpaper, clock, notifications, and lost-phone contact details, with notes on model and One UI feature differences.
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Your Samsung lock screen is both a security boundary and a glanceable dashboard, but its settings and features vary by Galaxy model, One UI version, and region. You can change the screen lock, wallpaper, clock, widgets, shortcuts, and notification display in Settings; newer features such as the Now bar are available only on supported devices.

What the Samsung lock screen does

Samsung describes the lock screen as a way to prevent accidental touch actions and protect information, including through biometrics, while still allowing access to simple information and basic features without unlocking. That balance is the point: choose what is convenient to see at a glance without exposing information you want private.

As Samsung puts it in its One UI documentation, “The Lock screen prevents unintended actions from accidental screen touches.”

How to change your Samsung screen lock

  1. Open Settings and tap Lock screen and AOD.
  2. Tap Screen lock and biometrics.
  3. Select an available lock method and follow the prompts. For a pattern, draw and confirm it; Samsung’s setup may also ask you to add a hint.

Samsung documents PIN, password, pattern, face recognition, and fingerprint options, as well as the less secure Swipe and None choices. Availability varies by model and software version. Face or fingerprint unlock requires a registered pattern, PIN, or password as a fallback, and Samsung says that fallback credential is required after a restart or power-on. See Samsung’s screen-lock and lock-screen guide for its documented setup flow.

How to change the lock-screen wallpaper, clock, and shortcuts

  1. Open Settings and tap Wallpaper and style.
  2. Tap Change wallpapers, choose a wallpaper, and select which screen to update when prompted.
  3. Adjust the available clock style, widgets, or buttons, then apply your changes.

On One UI 7, Samsung also documents resizing and repositioning the clock and adding lock-screen widgets and shortcuts. One UI 8.0 update notes for the Galaxy S24 describe clock styling that adapts around the shape of a selected photo, along with wallpaper suggestions. Those update notes caution that details can vary by model, country, and network operator; feature availability should not be assumed across all Galaxy phones.

Samsung’s lock-screen guide lists the wallpaper and appearance steps, while its One UI 7 feature page describes the newer clock, widget, and shortcut options.

How to show or hide lock-screen notifications

During screen-lock setup, Samsung lets you choose whether notifications appear on the lock screen and select a display style. Anything allowed to display on a locked phone may be visible to someone looking at it, so choose a style that fits your privacy needs. Check the notification-content controls on your own software version: the available labels and choices may differ.

What the Now bar is—and which Galaxy phones have it

The Now bar is an area for live or ongoing activity information. Samsung’s One UI 7 feature page describes live notifications appearing in the Now bar, status bar, and notification panel; it also documents grouped notifications shown as card stacks. Examples of Now bar activities include media controls, a stopwatch, timer, voice recorder, and Samsung Health.

Do not treat those examples as a promise that every Galaxy has the same bar or controls. Samsung’s Korean support article, dated 2026-02-26, documents Now bar on the Galaxy S26 series with One UI 8.5, listing notifications, music, and timers. It says compatible content can be selected under Settings > Lock screen and AOD and warns that country and model support can differ. Samsung’s One UI 7 rollout announcement said rollout would begin on 2025-04-07 with Galaxy S24, Z Fold6, and Z Flip6 families and expand gradually; that historical announcement does not establish that every listed or older device has every feature now.

How to add contact details for a lost phone

  1. Open Settings and tap Lock screen and AOD.
  2. Tap Contact information.
  3. Enter a telephone number or email address and save it.

Choose only contact details you are comfortable displaying on the lock screen, where a person who finds the phone may be able to read them. Samsung documents this option in its lock-screen guide.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

If your settings do not match these steps

Samsung notes that lock methods vary by model and software version, and settings labels can shift between One UI releases. Use Settings search to find terms such as “screen lock,” “wallpaper,” or “contact information” if a path differs on your phone. Treat version-specific features—including the Now bar—as conditional on your model, software, and region rather than universal Galaxy settings.
