Description

From the listing uploaded by “appupdater”.

Fine Lock is a community solution. It has nothing to do with Samsung Electronics and Samsung Mobile. Good Lock and Galaxy Labs are great official tools for customizing and optimizing Android experience on Samsung devices running official Oreo and One UI. 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 Galaxy Labs modules. Fine Lock does not support Samsung devices running AOSP OS build, such as LineageOS. Due to compliance with Google Play policy, Fine Lock cannot download any modules for you. Please get the latest APK modules from a trusted source such as APKMirror or Sammobile. PRO features: • Module app shortcuts in home screen, • Background check for updates, • Hide modules that are not installed, • Dynamic wallpaper, which changes your wallpaper based on device's Dark/Night modes. Requires Android 9 or later, and scheduled Dark/Night mode. Before you make any purchase, please make sure you have the latest Fine Lock installed. If your PRO features are not unlocked within 60 minutes after purchase, please contact me ASAP. Make sure you give me your Order ID, which always starts with GPA. and can be found in an email from Google Play. The app is made for Samsung devices running official Samsung's Android 8 and Android 9+ with One UI. It does not work and may crash on other models made by other brands. If you have it installed on a device made by other brands, please uninstall it. The amazing sample screenshots are created by marik6it.
