In this final instalment, Samsung Newsroom editors and the Good Lock development team put the spotlight on some of the standout features.

Wonderland: Dynamic Customisation 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 customised independently for greater creative freedom.

Users can layer various design elements — such as images, text, videos and particle effects ¹ — 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 personalise 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+: Customised Notifications That Catch the Eye

Edge lighting+ transforms everyday notifications into eye-catching visuals — adding a personalised touch to every alert that appears on the screen. Through the Set Custom Style menu, users can fully customise the image, colour 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.

▲ Style by keyword

Additional customisation 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, personalised notifications with minimal effort.

Nice Shot: Effortless Screenshot Management

Nice Shot streamlines screenshot management — making it easy to capture, delete and organise 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 personalised experience and the Samsung developers dedicated to making that vision a reality. By delivering greater convenience and deeper customisation, 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

But which Good Lock features are users loving the most? The first part of this series explored the Home Up module. In this second instalment, Samsung Newsroom unveils the top three most popular features.¹

Good Lock’s No. 1 Feature: Sound Assistant

Ever wished the volume could be tweaked just a little more precisely when listening to music? Good Lock’s Sound Assistant was designed to address exactly these everyday audio frustrations. The feature has surpassed 21 million cumulative downloads since its release, making it the most widely used module in the Good Lock suite.

Sound Assistant allows users to fine-tune volume levels in increments from one to 10, enabling precise control for an optimal listening experience. The volume panel’s appearance can be customised, delivering satisfaction not only to the ears but also to the eyes.

Users can manage volume settings for individual apps, assign the volume buttons to control media volume instead of ringtone volume and prevent media volume from decreasing during navigation use — eliminating minor inconveniences tied to personal preferences. These subtle yet impactful elements make Sound Assistant a standout feature that delivers meaningful improvements to the everyday audio experience.

Good Lock’s No. 2 Feature: Theme Park

Theme Park, a feature that lets users personalise various user interface (UI) elements of their smartphones with custom themes, has surpassed 17 million cumulative downloads. Curating a stylish theme but unsure how to choose the right colour combination? Theme Park makes it easy to craft a visually cohesive and balanced look.

Users can customise the colour scheme of individual UI components — including the keyboard, quick panel and messaging interface or let the feature automatically generate a harmonious palette based on a selected background image. This intuitive tool allows even those without design experience to personalise their device with ease and style.

▲ Theme Park

With the One UI 7 update, advanced customisation options have taken creativity to the next level. Users can now personalise not only app icons but also the shape and colour of home screen folders. For those looking to design custom icons and folder styles, the Create Icon Theme feature within Theme Park offers a simple yet powerful way to bring a unique aesthetic to the home screen.

Good Lock’s No. 3 Feature: One Hand Operation+

Ranking third among the most-used Good Lock features, One Hand Operation+ has proven its practicality with more than 16 million cumulative downloads.

This feature enables users to perform frequently used smartphone functions with a single thumb gesture, making it particularly helpful for multi-tasking throughout the day. Whether holding a drink in one hand or navigating through a crowded bus on the way to work, One Hand Operation+ guarantees users smooth, effortless control of their device.

The tool supports both left and right-handed users and allows specific functions to be assigned to horizontal, vertical or diagonal gestures. For instance, a left horizontal swipe could be set to “Back,” a right downward diagonal swipe to “Home” and an upward diagonal swipe to open “Recent Apps” or launch AI Select.

Users can further customise and refine gesture control settings to match their preferences and usage patterns. Options include adjusting the touch recognition range and gesture vibration intensity, excluding specific apps from gesture activation and even configuring gestures for the S Pen. This feature is especially useful in busy daily routines — an underrated yet powerful capability that delivers exceptional convenience with a single, simple gesture.

This overview of the top three most popular Good Lock features highlights the customisation functions Galaxy users rely on most in their daily lives. With many capabilities still left to explore, however, Good Lock has much more to offer. In the third and final instalment of this series, Samsung Newsroom will share expert tips and recommendations from the Good Lock development team.

Among the many enhancements, the upgraded Home Up module stands out — introducing greater design flexibility and significantly expanding home screen customisation capabilities. Samsung Newsroom explores the latest in UI personalisation with an in-depth look at what the new Home Up has to offer.

DIY Home Screen: A Fresh Take on App Layout and Organisation

Breaking away from traditional grids and uniform app icons, the DIY Home Screen feature in Home Up empowers users to design a layout that reflects their unique style. Apps, widgets and folders can all be freely resized and repositioned — much like customising the pages of a planner.

▲ DIY Home Screen

For a playful touch, users can cleverly conceal app icons underneath decorative elements with sticker and layer tools. Simply add a sticker to the home screen, place it over an app icon and adjust the layer settings. This setup transforms the sticker into a fun shortcut that launches the hidden app when tapped.

Show Favorites: Display or Hide the Favourite Apps Row

The fixed row of favourites at the bottom of the home screen is a familiar element on most smartphones. With Good Lock, however, this default layout is easy to customise. Users who prefer a cleaner, more minimalist aesthetic can disable the Show Favourites option in the Home Up menu for a simplified and refreshed home screen experience.

Home Gesture Animation: Fine-Tuned Control for Smoother Navigation

The Home Gesture Animation feature — found under Good Lock > Home Up > Gesture Settings — is perfect for users who want to add a touch of personality to every interaction. The feature offers a unique way to customise the transition animations activated when returning from an app to the home screen, making even the simplest gestures more expressive and enjoyable.

Alongside the four preset animation styles, Advanced Tuning provide granular control over aspects like speed and vibration for a more refined user experience.
