Download Good Lock APK

Good Lock from Samsung Electronics helps owners of Samsung smartphones shape the system to their own taste. It works through plugins, each handling one part of the interface: the status bar, the quick panel, the lock screen, the keyboard, and also multi-window behaviour, sound and Routine automations.

The main modules are named after what they do. LockStar builds new lock screens and always-on display styles, ClockFace picks clock looks, NavStar arranges navigation buttons and swipe gestures, Home Up refines the One UI Home launcher, QuickStar tidies the top bar and quick panel, and Wonderland produces backgrounds that shift as the phone moves. Further plugins cover narrower jobs.

It suits people who enjoy personalising their phone and are comfortable exploring settings. The program targets Samsung devices, and some models may not be supported. The interface is offered in Korean, English, Chinese and Japanese.
