Lockscreen Customisation

Dear Customer,
Thank you for contacting Samsung Gulf Electronics Customer Support.
Regarding the lock screen “poster-like clock with depth effect” and the wrap-around style clock you mentioned, this is part of Samsung’s evolving One UI lock screen customization experience. However, the availability of these advanced effects depends on the device model and One UI version.
For Galaxy A series devices, Good Lock and stock One UI customization options may provide limited lock screen clock styles, but the full “depth effect / poster-style immersive clock” feature is not universally available across all models or One UI builds. Even within One UI 8.5 concepts, some effects may be restricted to supported flagship models.
You may try the following available options:
Go to Settings > Lock screen > Clock style and check available styles
Install Good Lock from Galaxy Store and check LockStar module (if supported on your device/region)
Ensure your device is updated to the latest software version
If the feature is not visible in your customization settings, it means it is currently not supported for your device model or software configuration.
