Fine Lock

Good Lock and Good Guardians (previously 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 select 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 Good Guardians modules.

You can download Good Lock and Good Guardians modules (completely safe to install) from APKMirror via the links below. Devices running One UI Core are only compatible with some modules. For settings of LockStar, MultiStar, NotiStar and QuickStar remain after reboot on One UI 2 and later, you need to install Good Lock. Since the February 2022 updates, Good Guardians modules do require Good Guardians and Good Guardians Agent. The duo also act like the "supervisors" for Guardians modules to be fully functional. So, even though you may see a message like "Country not supported" when you launch Good Guardians, they need to be there anyway.

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.
