Good Lock

Samsung’s toolkit for personalising One UI

Good Lock is a Samsung utility suite for people who want more control over how their phone looks and behaves. Rather than offering one single setting screen, it brings together optional tools for areas such as the lock screen, always-on display, navigation controls, status bar, Quick Panel and keyboard. It is aimed at Samsung smartphone users who find the standard One UI layout too limited or want to adjust individual parts without changing the whole interface.

Choose only the tools you need

Good Lock works through separate plugins, so you can explore the parts that match your habits. LockStar lets you arrange lock-screen elements and create different lock-screen and always-on display designs. ClockFace adds alternative clock styles. NavStar handles navigation-bar buttons and swipe gestures, while Home Up provides extra controls for the One UI Home experience.

• QuickStar: adjust the top bar and Quick Panel for a cleaner arrangement.
• Wonderland: create backgrounds with movement that responds to the phone’s motion.
• Additional plugins: extend the suite into other interface, audio, multi-window and routine-related settings.

Best suited to Galaxy owners who like fine control

This is a practical choice for users who enjoy tuning their phone one section at a time, especially those who regularly use the Quick Panel, navigation gestures or always-on display. It is less useful if you want a simple, fixed interface with no extra configuration. Plugin availability and compatibility can vary by Samsung device and Android version, so some phones may not support every option. The app supports Korean, English, Chinese and Japanese.
