Introduction
Samsung continues to refine its software ecosystem alongside the rollout of Android 17-based One UI 9.0. While the company introduced the new interface in May with several improvements and visual enhancements, not every Good Lock module was immediately ready for the transition. One of the biggest missing pieces was LockStar, a customization plugin widely used by Galaxy enthusiasts to personalize their lock screens. That compatibility gap has now been closed, allowing Galaxy S26 owners to enjoy one of Samsung’s most popular customization tools without limitations.
Samsung Updates LockStar for One UI 9.0 Compatibility
Samsung has officially released a new update for the LockStar Good Lock module, bringing the application to version 9.0.00.5. The update primarily focuses on making the plugin fully compatible with One UI 9.0, which is based on Android 17.
When Samsung first announced One UI 9.0 earlier this year, LockStar was listed among the modules that were temporarily unsupported. As a result, users installing the latest firmware found the application disabled and unavailable inside the Good Lock suite.
The newest release removes that restriction entirely, restoring full functionality for supported devices.
Galaxy S26 Series Becomes the First Beneficiary
At the moment, the Galaxy S26 lineup remains the only smartphone family officially running the stable version of One UI 9.0. Because of that, these devices are also the first to benefit from the updated LockStar release.
Users who install version 9.0.00.5 will immediately notice that LockStar is no longer greyed out inside Good Lock. Instead, the plugin becomes fully operational, allowing users to customize lock screen layouts, clock positioning, widgets, shortcuts, notifications, wallpapers, and many other interface elements.
This update completes another important step in
Additional Improvement Brings Flip Cover Animation Support
Besides compatibility fixes, Samsung included another enhancement within the update.
The changelog introduces support for Flip Cover Screen Unlock Animation, improving the visual experience for users who rely on Samsung’s official flip covers and compatible accessories.
Although this addition may appear relatively small compared to the compatibility update, it reflects Samsung’s continued attention to polish and user experience across both hardware and software.
Installing the Latest LockStar Update
Samsung provides two simple methods for obtaining the newest version.
Update Through Galaxy Store
Users can open:
Galaxy Store → Menu → Updates → Update All
This automatically installs the latest version if it is available in their region.
Update Through Good Lock
Alternatively, users can open:
Good Lock → Plugins
If an update is available, an update icon will appear next to LockStar. Selecting it downloads and installs the newest version immediately.
After installation, LockStar becomes fully usable without requiring any additional configuration.
One UI 9.0 Rollout Continues
Samsung is expected to significantly expand the availability of One UI 9.0 during the coming weeks.

As additional flagship devices receive Android 17, Samsung will likely continue updating remaining Good Lock modules to ensure every customization feature functions correctly from day one.
Why LockStar Matters to Samsung Users
Unlike many Android manufacturers that offer limited personalization, Samsung has built an extensive ecosystem around Good Lock. LockStar has become one of the platform’s most frequently used modules because it allows users to redesign nearly every aspect of the lock screen without requiring third-party launchers or root access.
For power users, creators, and enthusiasts, compatibility updates like this are more than routine bug fixes. They preserve one of Samsung’s strongest competitive advantages: deep system-level customization.
With Android becoming increasingly standardized across manufacturers, software personalization continues to differentiate Galaxy devices from much of the competition.
Deep Analysis: One UI 9.0 Deployment and Linux-Based Update Verification Commands
Software compatibility updates often appear simple on the surface, but they require extensive framework validation behind the scenes. Every Good Lock module interacts with Android’s SystemUI components, meaning even small API changes introduced in Android 17 can temporarily disable plugins until developers rebuild compatibility.
Developers and advanced users can inspect Android packages using common Linux and Android Debug Bridge commands.
adb devices adb shell pm list packages adb shell dumpsys package com.samsung.android.lockstar adb shell getprop ro.build.version.release adb shell getprop ro.build.version.sdk adb shell cmd package list packages adb shell settings list secure adb shell settings list system adb shell wm size adb shell wm density adb logcat adb bugreport adb shell dumpsys activity adb shell dumpsys window adb shell pm path com.samsung.android.lockstar adb install app.apk adb uninstall package.name adb shell am start adb reboot adb shell top
These commands help developers verify installation status, monitor package behavior, inspect framework compatibility, collect debugging information, and diagnose update-related issues. Samsung’s modular Good Lock architecture also allows individual plugins like LockStar to receive independent updates through Galaxy Store rather than waiting for a complete firmware release. This approach shortens deployment cycles, enables faster bug fixes, and minimizes disruption for users adopting the latest Android version. As One UI evolves, maintaining API stability between the operating system and optional customization modules becomes increasingly important, especially as Samsung expands AI features, dynamic lock screen elements, and foldable device optimizations. Continuous module updates demonstrate a mature software maintenance strategy that separates feature delivery from full operating system upgrades, providing users with quicker access to improvements while reducing dependency on major firmware releases.
