Fix the One UI 9 Lock Screen Clock That Keeps Moving Out of Place

Step 1: Compare the lock screen to the LockStar preview

Open Good Lock’s LockStar editor and note where you placed the clock and how close the time sits to the date.

Lock the phone, then wake it and check whether the clock has moved higher, lower, or has a different gap from the date than what you set.

Tip: Check the Always On Display too, since the same mismatch often shows up there.

Step 2: Watch for drift over time

Some users see the clock hold its position for a while before it moves, so give it a few lock/unlock cycles or let the phone sit idle before deciding it’s fixed.

Step 1: Open Lock Screen and AOD settings

Go to Settings > Lock Screen and AOD (shown as Lock Screen on some models).

Step 2: Tap Clock Style

Select Clock Style to see the available designs for your lock screen and AOD.

Step 3: Choose one of the phone's built-in clock styles

Pick a default Samsung clock design instead of a custom style supplied through ClockFace.

This is the exact step Samsung’s support team recommends, and it reliably keeps the clock from shifting for most affected users.

Tip: If a default style still moves out of place, that's unusual and worth reporting to Samsung directly.

Step 1: Open Apps settings

Go to Settings > Apps, then search for One UI Home.

Step 2: Clear the One UI Home cache

Tap One UI Home > Storage > Clear Cache.

Step 3: Repeat for the Always On Display app

Go back to Apps, find Always On Display, then tap Storage > Clear Cache.

Clearing cache doesn’t delete personal data, but it can reset some of your display customizations, so you may need to reapply a wallpaper or widget afterward.

Tip: Restart the phone after clearing both caches before you judge whether it helped.

Step 1: Open Good Lock and find LockStar

Open the Good Lock app and locate the LockStar module in your installed list.

Step 2: Uninstall LockStar

Tap LockStar, then uninstall it from the module’s details screen.

Expect to lose your current lock screen customizations, so note your layout before removing it.

Step 3: Reinstall it from Good Lock

Reinstall LockStar from Good Lock, then reapply your clock position and other lock screen customizations.

Tip: This is a short-term patch, not a permanent fix, so the issue may return after further updates.

Step 1: Open Samsung Members

Open the Samsung Members app, or use the Good Lock app’s support and feedback channel, to submit an error report.

Step 2: Attach logs or a screen recording

Include an error report with logs, or a screenshot or screen recording showing the clock moving, so Samsung’s developers can reproduce it.

If you’re on the One UI Beta Program, go to Beta Feedback instead and attach the same evidence there.

Step 1: Open the Galaxy Store

Open the Galaxy Store app and check for updates to your installed apps, including Always On Display.

Step 2: Install the AOD app update when it appears

Update the AOD app as soon as it’s available, since Samsung has scheduled the fix for release through this app rather than a full system update.

Tip: An AOD update landing in November isn't guaranteed to fully resolve the issue, so keep your default clock style as a fallback until you confirm it's fixed.
