Good Lock and Galaxy Labs are great official tools for customizing and optimizing Android experience on Samsung devices. Unfortunately, they're only available for download on Galaxy Store in a few selected markets. Even if you have them installed, they may not work at all. Fine Lock is here to solve the problem by acting like a launcher for Good Lock and Galaxy Labs modules.

You can download Good Lock and Galaxy Labs modules (completely safe to install) from APKMirror via the links below. Some modules may not be installable on affordable models: J and M series, A01 → A30, due to software limitation. Please contact Samsung Support for more info. Some features are only available on S and Note devices because they have all the required software features. I don't develop the modules and Fine Lock cannot intercept their functionalities. For MultiStar, NotiStar, Task Changer and QuickStar to work correctly on Android 10, you need to install Good Lock which acts like a dependency. You can get it from the module list below.

To record your screen on Android 9, or A10 → A30S running Android 10, install NiceShot 1.0.15 from the module list.

So why APKMirror? It's a very trusted third party to provide free pure original APKs. It's maintained by the team at Android Police which is the top news source about Android. Thousands of safe APK downloads are requested from APKMirror everyday. More importantly, APKs there are not restricted by regions, so you can download any free APKs which are not made available in your country, such as some Good Lock modules.

Fine Lock is made for Samsung devices running Samsung's Android Oreo or later. Some modules require Android Pie or later. It does not work and may crash on other models. If you have it installed on a device made by other brands, please uninstall it.
