One UI 9 Beta and Good Lock: What Works and What Doesn't

Samsung's One UI 9 beta has landed on the Galaxy S26, bringing a host of changes. But if you're a Good Lock user, you might wonder which modules will survive the update. Samsung has officially shared a compatibility list to help you decide whether to take the plunge. Here’s everything you need to know about Good Lock and One UI 9.

What is Good Lock and why does One UI 9 matter for it?

Good Lock is Samsung's suite of customization modules that let you tweak everything from the quick panel to the lock screen. When a major OS update like One UI 9 arrives, some modules may stop working because they rely on internal system APIs that change. Samsung must update each module to match the new OS version. This means before updating, you should check if your favorite modules are compatible to avoid losing customizations.

Which Good Lock modules are compatible with One UI 9 beta?

According to Samsung, the following modules work out of the box with the One UI 9 beta: Dropship (drag-and-drop file sharing), Nice Shot (screenshot enhancements), Edge Touch (edge panel sensitivity), Theme Park (custom themes), and Keys Cafe (keyboard customization). These have been updated to support the new OS. Also compatible are Home Up, Task Changer, Routines+, and MultiStar. You can install these modules from the Galaxy Store and they should function normally.

Which modules are still under development for One UI 9?

Samsung reports that several popular modules are not yet ready: NavStar (navigation bar tweaks), LockStar (lock screen customization), QuickStar (quick panel adjustments), ClockFace (AOD clock designs), One Hand Operation+ (gesture controls), and Good Lock’s core (the launcher itself). These are listed as “in development” and will be updated after the beta period. If you upgrade to One UI 9, these modules will be disabled or may cause instability. Samsung recommends waiting for full compatibility before relying on them.

What happens if you install One UI 9 and your Good Lock modules are not compatible?

If you install the One UI 9 beta and a module isn't compatible, the app will either not open or will crash. You might also notice that custom settings disappear. For example, if you use LockStar to design your lock screen, that configuration will be lost until LockStar is updated. Samsung warns that system instability could occur if you force an incompatible module. Your phone won’t be damaged, but you’ll lose access to those customizations. It's best to back up your settings before updating and disable any non-working modules via Good Lock’s settings.

Should you upgrade to One UI 9 beta if you rely on Good Lock?

It depends on which modules you use. If your primary modules are in the compatible list (like Keys Cafe or Edge Touch), upgrading should be safe. But if you heavily depend on NavStar, LockStar, or QuickStar, you might want to wait until they receive updates. Samsung typically releases Good Lock updates within a few weeks of a beta launch. You can check the Good Lock forum or Samsung Members app for update announcements. For now, consider this early beta as a preview for developers and enthusiasts willing to sacrifice some customizations temporarily.

How can you check if a specific Good Lock module works after updating?

After installing One UI 9 beta, open the Good Lock app. Modules that are compatible will show a green checkmark or say “Compatible.” Incompatible modules will be grayed out with a message like “Not supported in current software version.” You can also tap on each module to see its version and status. For the most accurate info, visit the Good Lock section in the Galaxy Store – Samsung lists compatibility notes there. If a module is not updated, uninstall it temporarily to avoid any conflict. Keep an eye on Samsung’s official Good Lock update blog for announcements.

What should you do if your favorite module isn't ready yet?

First, do not downgrade your OS – you can’t easily revert from the beta. Instead, wait for Samsung to release updates for the modules. You can enable automatic updates in the Galaxy Store under Good Lock so you get the fix as soon as it's out. Meanwhile, you can use alternative built-in features: for example, One UI 9’s new lock screen customization options partially replace LockStar. Also, post feedback on Samsung Members to help developers prioritize fixes. Samsung has historically updated all major Good Lock modules within a month of a public beta launch. Patience is key.
