If you’ve ever wanted to tweak your Android phone beyond what the system allows, customizing everything from your lock screen layout to task switcher animations, you’ve probably run into limitations. Stock Android offers aesthetic flexibility thanks to Material You, and other manufacturers like OnePlus allow limited UI modifications. When it comes to personalizing your phone at a system level, Samsung stands out above other manufacturers thanks to Good Lock.
Unlike third-party launchers or mods that often require root access or ADB tricks, Good Lock is official, stable, and deeply integrated into One UI. And it’s available for nearly all Galaxy devices. Here’s how Samsung quietly built Good Lock into Android’s most impressive customization platform.

Good Lock started as a niche utility back in 2016. However, Samsung expanded Good Lock’s scope with each new version of One UI. Today, it has evolved into a comprehensive suite of tools that let users control every visual and functional aspect of their phone without compromising stability.
Good Lock is now a collection of tightly integrated modules. Instead of offering a bloated all-in-one app, Samsung follows a modular system. It allows users to pick and choose what they want to tweak, or leave it alone if they’re happy with the defaults.
With the LockStar module, you can customize your lock screen, set different layouts for different times of day, and even add new widgets. NavStar allows an overhaul of the navigation bar, including custom button layouts and gestures. Then there’s Theme Park for designing your themes, including icons, fonts, and color palettes that match your wallpaper. Together, these modules unlock a level of control over the UI unmatched by any other Android brand, without compromising security or performance.
Good Lock offers deep personalization options
It goes far beyond what stock Android offers
Google’s Material You design language introduced dynamic theming, letting users personalize the system’s color palette based on their wallpaper. But compared to Good Lock’s capabilities, it feels limited.
Material You can’t let you change the layout of your lock screen. You can’t move your Quick Settings toggles or add a vertical stack of recent apps. You can neither add an extra navigation button nor create your theme from scratch. On the other hand, Good Lock lets you personalize your phone without needing root access or developer trickery.
Good Lock’s customization options aren’t limited to aesthetic tweaks either. Modules like SoundAssistant let you control per-app volume, add custom EQ settings, or make the volume bar vertical. One Hand Operation + allows you to assign thumb gestures to any command, shortcut, or app. MultiStar adds real multitasking power to Samsung’s already excellent split-screen support. These tools make your phone more personal and functional.
A quiet evolution through user feedback

Good Lock often flies under the radar because Samsung doesn’t advertise it heavily. You won’t see splashy marketing campaigns for it, and it does not come preinstalled on most Galaxy phones. Most users discover it through forums and tech communities.
But this relative obscurity has worked in Good Lock’s favor. It has cultivated a passionate user base that shares feedback, bugs, and feature requests. Samsung has also consistently updated modules in response, often aligning Good Lock updates with new One UI releases. When One UI 7 rolled out, Good Lock’s modules were quickly updated to support the latest design changes. It also revamped its Home Up module to offer even more home screen personalization options.
Good Lock makes it easy to tweak your phone settings
There’s no steep learning curve
Good Lock strikes a rare balance by offering deep customization power for Android tinkerers, but wraps it in an intuitive, well-designed interface that even casual users can understand. Personalizing your phone is as simple as downloading the Good Lock container app and installing the modules. You can make quick adjustments with a few taps and drag-and-drop editing. Unlike third-party modding tools, which often have a steep learning curve or unstable behavior, Good Lock is much easier to use.
Unlock the full power of your Samsung Galaxy phone with Good Lock
Good Lock may not come preinstalled on phones or highlighted during Samsung’s flashy launch events, but its impact on the user experience is undeniable. Samsung has built a powerful customization suite by offering users granular control over how their phones look, feel, and function.
Whether you want to tweak a few UI elements or completely overhaul your device behavior, Good Lock makes it possible without root access or third-party hacks. In a time when most Android manufacturers are streamlining their skins and stripping out features in the name of simplicity, Samsung has doubled down on offering more personalization features. Through consistent updates, thoughtful design, and responsiveness to user feedback, Good Lock has become a quiet revolution in Android customization.
