The One UI 2.0 update is steadily rolling out for a plethora of Samsung Galaxy devices, but one side effect was the issues with the popular customization tool Good Lock on Android 10.

If you were unaware, Good Lock is essentially a theming tool for Samsung devices with some pretty impressive add-on modules that allow for tweaking of things like the EdgeLighting, lock screen, plus tons more on top. The biggest issue with Android 10 was that it essentially broke the app on any Galaxy devices that updated to One UI 2.0.

Update 02/03: Good Lock 2020 support is now available for those already running Android 10 on their Galaxy device. It isn’t available in all regions just yet but we expect support to steadily roll out across the globe over the coming weeks. If you haven’t already installed Good Lock on your Galaxy device, you can download it from Samsung’s Galaxy Store right here.

Luckily, the issues are now set to be rectified, as Samsung has confirmed that the 2020 version of Good Lock, complete with Android 10 compatibility, is set to be released on February 3, 2020 (via SamMobile). The update was confirmed by Samsung in South Korea — who happened to even provide us with a changelog for the new version. With some rudimentary translation, it confirms several upcoming features including more lock screen control options with LockStar. You can see the full (translated) changelog below:

Samsung suggests that this new version of Good Lock has had to be heavily modified to work with the full Android 10 update, with core features of the app having been improved across the board. The NavStar module is not working but will be in a future update once this 2020 version has been released.

Good Lock 2020 will start rolling out on February 3 in South Korea. We expect a global rollout in the weeks following this initial relaunch.
