Unlock the Full Potential of Your Samsung Galaxy with Good Lock Modules
What is Samsung Good Lock?
Good Lock is an official Samsung app that acts as a hub for a growing collection of add‑on modules. Each module dives deep into a specific area of One UI – lock screen, navigation, camera, multitasking and more – giving users a level of customisation that previously required custom ROMs.
Who can use it?
The app runs on any Samsung Galaxy phone with One UI 6 or later. That includes the Samsung Galaxy S23, Samsung Galaxy S24, the upcoming Samsung Galaxy S25, the Samsung Galaxy Z Fold5, Samsung Galaxy Z Flip5, and the Samsung Galaxy Tab S9 series. Good Lock is available through the Samsung Galaxy Store and, since late 2025, also on the Google Play Store.
How to install Good Lock
Open the Galaxy Store (or Play Store), search for Good Lock, tap Install and launch the app. Inside Good Lock you will see four main sections – Make up, Life up, Clock and Extensions – and you can download individual modules by tapping the download icon next to each one.
Key modules to try
Theme Park lets you create custom themes by mixing colours, icon shapes, fonts and wallpapers. An AI theme generator added in 2026 can create a complete colour scheme from a simple text description.
One‑Handed Operation+ adds six edge gestures that work alongside the standard navigation bar, making it easier to reach the top of large devices such as the Samsung Galaxy S25 Ultra or Z Fold5.
LockStar provides a WYSIWYG editor for the lock screen. You can drag the clock, date, widgets and app shortcuts to any position, hide unwanted elements and even add animated unlock effects like Swirl or Curtain.
MultiStar expands split‑screen and pop‑up window support to any app, adds home‑screen app pairs for instant split‑screen launch, and gives foldable users control over how apps behave on cover and main screens.
RegiStar unlocks back‑tap actions, side‑button remapping and a customisable settings menu, letting you hide rarely used sections and keep frequently used ones at the top.
NavStar lets you redesign the navigation bar – change button order, colours, background and even add a hide‑bar button. For gesture navigation you can fine‑tune sensitivity on each side of the screen.
Camera Assistant activates hidden camera modes such as the 24‑megapixel AI‑fusion mode, focus peaking in Pro mode, auto HDR and an Astro photo shortcut for night‑sky shots.
NotiStar stores a full notification history, offers keyword‑based filtering and lets you control which alerts appear on the lock screen.
Other useful modules
Home Up customises the launcher grid and app drawer, Keys Cafe tweaks keyboard layout and sounds, QuickStar manages status‑bar icons, Routines+ adds advanced Bixby automations, Wonderland delivers dynamic parallax wallpapers, ClockFace creates custom Always‑On Display clocks, Game Booster+ optimises gaming performance, Pentastic refines S Pen pointer styles and Nice Catch logs system changes.
Tips for getting the most out of Good Lock
Start with two or three modules that solve a specific problem – for example LockStar for lock‑screen widgets and NavStar for a personalised navigation bar. Install additional modules gradually to keep storage use low. Remember that some modules may be region‑locked, so check availability in your country.
With Good Lock, a Samsung Galaxy S25 or any compatible device can become a truly personalised tool, turning One UI into a platform that adapts to your workflow rather than the other way around.
