About this app

Important note: One UI Core models are no longer supported. This is Samsung's decision and has nothing to do with Fine Lock developer.

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.

It is a cool app but I was ready to go back to my phone's original look so I deleted the apps thinking it would change. Nope, I reset my phone settings and it only took away half of the changes I made through 'Theme Park' and 'KeysCafe'. My keyboard is still different as is the text color of my phone and the bubbles of my messages. Oh, and there is no trace of those apps being on my phone and I cannot find them in the app store again. I cannot figure out how to get rid of those settings I made.

Fine lock let's me personalize my Galaxy without affecting it's performance. I used to download themes to my phone, but installing just a couple, my phone would slow down and freeze and lock up. With Fine Lock, I can personalize it even further than with themes, and my phone won't freeze or slow down. And there are hundreds of different ways I can customize my phone!

RegiStar requires Android 13 + One UI 5. According to Samsung's schedule, it will be released for your device by the end of January 2023. Remember to install all newest updates for the modules after you install One UI 5 and you're all set. Fine Lock will prompt you for that. Let me know if you need any help. Best regards.

This release brings some following fixes:
• Corrected Indonesian translation,
• Ukrainian translation,
• Notification icon and option in Fine Lock's Settings screen.
• App shortcuts for Pro users.
