Parts one and two of this series explored Good Lock, Samsung Electronics’ user interface (UI) customization app developed for Galaxy devices — highlighting the platform’s evolution with the One UI 7 update, from the redesigned Home Up module to the top three most-used tools.
In this final installment, Samsung Newsroom editors and the Good Lock development team spotlight standout features.
Wonderland: Dynamic Customization for Lock and Home Screens
Wonderland enables users to create animated wallpapers for the lock and home screens — bringing a vibrant, dynamic aesthetic to the first screens encountered when the device is turned on.
Previously, the same wallpaper had to be applied to both the lock and home screens. However, in response to user feedback, each screen can now be customized independently for greater creative freedom.
Users can layer various design elements — such as images, text, videos and particle effects1 — and apply motion effects including left-right, up-down and front-back movement to create 3D wallpapers that respond dynamically to device tilt and touch.

Moreover, users can personalize the transition effects between the Always On Display (AOD) and the lock screen to add a stylish touch to their device’s first impression. Detailed controls over transition speed and depth allow for playful effects, such as stickers that appear and disappear over an image.
As one of Good Lock’s defining features, Wonderland combines creativity with the satisfaction of a visually immersive experience.

Edge Lighting+: Customized Notifications That Catch the Eye
Edge lighting+ transforms everyday notifications into eye-catching visuals — adding a personalized touch to every alert that appears on the screen.
Through the Set Custom Style menu, users can fully customize the image, color and animation that accompany incoming notifications. Beyond default images, stickers created on Galaxy devices can be applied to give each notification a unique and personal touch.

The Style by keyword menu allows users to assign specific effects to notifications containing certain keywords — ensuring that important messages stand out. For example, terms like “boss,” “report” or “meeting” can trigger distinct visuals for relevant notifications.

Additional customization options include changing the notification image to appear as an app icon or activating effects only when the screen is off.
Despite its wide range of features, Edge lighting+ makes it easy for users to create stylish, personalized notifications with minimal effort.
Nice Shot: Effortless Screenshot Management
Nice Shot streamlines screenshot management — making it easy to capture, delete and organize images the moment they appear on screen.
A delete button appears immediately after taking a screenshot, allowing users to remove images they don’t need without opening the Gallery app.

Furthermore, users can configure their device to automatically enable Do Not Disturb mode during screen recordings to prevent interruptions from notifications or messages.
As one of Good Lock’s most practical enhancements, Nice Shot adds everyday convenience to Galaxy devices.
The diverse Good Lock features showcased throughout this series reflect the thoughtful collaboration between Galaxy users seeking a truly personalized experience and the Samsung developers dedicated to making that vision a reality.
By delivering greater convenience and deeper customization, Good Lock continues to evolve in step with the needs of its users and the creativity of its developers — and this is just the beginning.
