Change Your Samsung Lock Screen Clock: Simple Steps

Updated 10 November 2026 · Standard formula, shown below

To change the clock on a Samsung Galaxy lock screen, open Settings > Lock screen and AOD > Edit Lock screen, tap the clock, and choose a style, color, or position that your phone offers. Menu names and available choices vary by model and software version; on some phones, you can also press and hold the lock screen to open its editor.

What the lock screen clock controls

The lock screen clock is the time display shown before you unlock your phone. Samsung lets you adjust its appearance on supported Galaxy devices, but the exact set of controls depends on the device, region, and One UI version. A phone may offer several fonts and colors, while another may show fewer choices or arrange the controls differently.

These settings change the clock’s presentation, not the time itself. If the displayed time is wrong, check the date, time, and time-zone settings instead of changing the clock style. Likewise, changing the lock screen clock does not necessarily change the clock on the Home screen or in apps.

Change the clock in Settings

Unlock the phone and open Settings.
Tap Lock screen and AOD. On some software versions, the section may be called Lock screen.
Choose Edit Lock screen. Depending on the menu, you may see a lock-screen preview or an editing screen directly.
Tap the clock in the preview. If tapping does not select it, look for a clock or style control on the editing screen.
Choose a clock design, then adjust available options such as font, color, or placement.
Tap Done or Save to apply the change. The button name can differ.

Check the preview before saving. A color that looks clear against one wallpaper may be difficult to read against another, and a larger clock can cover more of the image. If you do not see an editing option, use the alternatives and troubleshooting steps below rather than assuming your phone is broken.

Use the lock-screen editor and explore extra options

On many newer Galaxy phones, the editor can be opened from the lock screen: wake the display, then touch and hold an empty area of the lock screen. If prompted, unlock the phone to edit. Select the clock in the preview, make your changes, and save them. This shortcut is not available on every model or software version.

Depending on the device, clock-related options may include:

Style or font: Pick a different numeral design. Some styles are compact; others are more decorative.
Color: Select a shade that stands out against the wallpaper. Automatic or suggested colors may appear in some editors.
Size or position: Some versions let you change the clock’s size or move it within the permitted area. Others use fixed layouts.
Additional lock-screen information: Separate controls may show notifications, date, or other items. These are not all part of the clock setting.
Always On Display: If supported and enabled, this is a separate display mode that can show a clock while the phone is idle. Its style and behavior may have their own settings.

Availability is not guaranteed: Samsung’s editor changes across devices and updates. If the clock itself is editable but you cannot find a particular color or layout, that option may simply not be offered on your model.

How to choose a readable clock

Start with legibility rather than decoration. Choose a clock color with strong contrast against the part of the wallpaper behind it, and preview the result in both bright and dim surroundings if you use the phone in varied lighting. A simple font is often easier to read at a glance than a thin or ornate one.

Consider how the clock fits with notifications and other lock-screen items. If a large design makes the screen feel crowded, try a smaller style or a less busy wallpaper. When changing the wallpaper later, review the clock again; a setting that worked with the old background may become hard to see.

Common problems and fixes

The menu names do not match: Search Settings for “Lock screen,” or open the lock-screen preview and look for an edit control. Menu organization differs across software versions.
Tapping the clock does nothing: Confirm that you are in edit mode, not just viewing the lock screen. Try the Settings route if the press-and-hold shortcut is unavailable.
The change did not stick: Return to the editor and look for Done or Save. Then lock the phone and wake it again to check the result.
There are fewer styles than expected: Options vary by model and software. Check for a system update through Settings if you want to rule out an older interface, but an update does not guarantee additional styles.
The clock looks different on the idle display: Check Always On Display settings separately. Its appearance may not follow every lock-screen clock choice.

A theme or wallpaper may also affect the overall appearance, but changing those is not required for a basic clock adjustment. Avoid installing an app just to change a built-in setting unless you have checked what permissions and display behavior it needs.

Frequently Asked Questions

Can I change the font and color of my Samsung lock screen clock?
Often, yes. Open the lock-screen editor, select the clock, and review the styles and colors shown. The available choices depend on your Galaxy model and software version.

Why can’t I move my lock screen clock?
Some versions let you adjust its position, while others use a fixed layout. If no position control appears when you select the clock, your current device or software may not support moving it.

Can I change the lock screen clock without changing the Home screen clock?
Yes. The lock-screen editor changes the lock-screen display. Home screen clock widgets and clocks inside apps have separate settings.

Does changing the clock affect Always On Display?
Not necessarily. Always On Display is a separate mode with its own options on supported phones. Check its settings and preview the idle display after editing the lock screen.

What should I do if the lock screen shows the wrong time?
Changing the style will not correct the time. Check the phone’s date, time, and time-zone settings in Settings, including any automatic time options available on your device.
