In early September 2020, we have two new modules: Pentastic, which is built specifically for S Pen, and Wonderland. You can download them from the home page. Penstatic supported devices include, but might not limit to, Note 9, Note 10 and Note 20 running Android 10. Devices without S Pen are not supported. Wonderland only works on Android 10 with One UI 2. One UI Core is not supported.

July 2020 update

The July 2020 include many bug fixes and improvements from both server side and app side. Users are highly recommended to update as soon as possible to receive the latest patches.

Server side:
App side (Fine Lock 1.1.11(41)):

Support for HomeUp

Since late April 2020, we have a new module called HomeUp. It will appear on your module list via a server-side update, which means you don't need to wait for a new update on Google Play. The only thing you need to do is restart Fine Lock and it will be there. However, HomeUp only works on A40+, S and Note devices running Android 10 and One UI 2 with the latest security patch and One UI Home from Galaxy Store. If your device is not supported, HomeUp will crash and you'll see something like the screenshot below:

HomeUp error

In that case, please do the following steps:

  1. If you have Fine Lock 1.1.10(40) or later, just make a long press on Home Up, and uninstall it.
  2. If you have Fine Lock 1.1.03(29) or earlier, re-install HomeUp APK, which can also be found in the module download section. Then open Settings → Apps, and remove HomeUp from your App list.

Support for Game Plugins

Thanks to a feature request, Fine Lock now supports managing Game Plugins on Android 10. You can find and get it from the Fine Lock home page. However, Game Plugins modules won't be managed. This is a server-side update, so there's no update required unless you have Fine Lock version 1.0.17(24) or an older version. In that case, please update Fine Lock right now via Google Play.

After you have Game Plugins installed, it will appear on your app list. Please launch it and follow what's on your screen to install Game Booster Plus, Daily Limits and Perf Z, which can be easily installed from Galaxy Store.

NavStar does not work on a few models

The NavStar crashes on a few models such including Note 10 series while it works perfectly on other ones including S10 series. Though it shows you "Fine Lock is stopped", this is actually a problem from Samsung and not from Fine Lock. If you experience the crash, please wait for the next release. Thank you very much for your patience, but I can do nothing about that. Only Samsung can fix the error.

Download options

Since March 2020, Android 10 and 9 users can jump straight to download pages of the latest versions of Good Lock modules without manually picking up from the list by selecting "Latest versions" in Download options. If you wish to use the old option, for example, to install an old module version, please select "Manually select versions" from the drop down menu.

Note for Android 8 and 9 users: If you have the latest versions of LockStar (, MultiStar (2.5.02), QuickStar ( and Fine Lock still says "There are updates available", please just ignore that and continue using these versions. The latest releases are only made to work on Android 10.

Good Lock

Since most of Unit modules require Good Lock to be installed so they can work correctly, such as LockStar, NotiStar, QuickStar and MultiStar, Good Lock is now included in the modules list and temporarily treated like a Family module. You can find and get it from the Fine Lock home page.
