There are a few things you should do first when you are using a new Samsung smartphone. One of those is downloading and installing Good Lock. Whether you own a Galaxy S24 model, Galaxy Z Fold 5, or an older Samsung phone, it’s an app that opens a near-endless array of software customization options. But what is Samsung Good Lock, and why is it important? Learn more about its modules’ features, availability, and installation steps below.

What is Samsung Good Lock?

Samsung Good Lock is an app with several downloadable utilities — or modules — that can customize your device or provide additional functionality. In short, Good Lock is a customization suite that makes Samsung’s One UI feel like a custom ROM.

The app has been around since the Samsung Galaxy S7 series and only included options to tweak lock screen elements on Samsung’s original TouchWiz UI — hence its name. However, Good Lock has been upgraded and modified by Samsung plenty since. In its current form, it provides customization features for lock screens, notifications, and even the stock clock face. It also enhances multitasking, the S Pen, and lets you run apps on the Galaxy Z Flip 5’s cover screen.

Notably, Good Lock doesn’t come with all these modules preinstalled. Instead, users can choose which they’d like to install through Good Lock.

Good Lock features

Nice Catch Samsung Good Lock

Let’s talk briefly about each module and what it does. All modules below support One UI 5.1 or newer running on Android 13 or newer. Most also work on older versions of Samsung’s One UI, but some, like Camera Assistant and RegiStar, require the latest version. Edge Lighting+ requires One UI 5.1.1. The modules are rather simple and don’t require a ton of explanation.

Camera Assistant

Camera Assistant adds a handful of tweaks to the One UI camera software. Users can toggle on Auto HDR when the phone detects the right conditions, activate Auto lens switching that lets the phone choose the best lens for any given shot, and even record video in photo mode by holding the shutter button.

Other settings let users snap additional shots after a timer runs out and increase the speed of the shutter by minimizing the number of frames captured. Users can also toggle Clean preview on HDMI displays, which removes settings and buttons when showing image previews on a large screen.


Clockface from Good Lock

Clockface lets you change your lock screen or AOD clock.
Clockface lets you customize the clock on your always-on display or lock screen. A couple of dozen options range from analog to digital and even text. I quite liked the panda bear clock you can choose as well. Most of the clocks let you customize things like color, some of the items, and other elements. Once done, set the clock, and it’ll appear on your lock screen or always-on display. All the clocks you customize are available under the My Clocks category, accessible from the bottom of the screen.


Dropship is a platform-agnostic file-sharing tool that, for now, is only available in South Korea’s Good Lock package. It allows users to create links to content, share those links to Android devices, iOS devices, and the web, and modify those sharing links if required. Users can also govern sharing limits, like limiting how many times the link can be shared, or how long it remains active.

Edge Lighting+

Edge Lighting+ offers users customization options for Samsung’s Edge Lighting feature. Users can adjust colors and effects, and pair these to notifications received. The module requires One UI 5.1.1 or newer.

Edge Touch

Only use EdgeTouch if you have problems with accidental taps on the edges of your screen.
Edge Touch is a potentially helpful app if accidental touches are a real problem. It lets you manually configure the parts of the screen that reject accidental touches. This feature already exists in Samsung phones by default without an app. However, this Samsung Good Lock module lets you increase or decrease the size for better use. We recommend hitting the Show Edge Zones option to see where Samsung puts the accidental touch protection by default before trying to mess with it.

Galaxy to Share

Galaxy to Share lets you backup and share Good Lock settings across Samsung devices. This is great for those with intricate Good Lock module setups that they’d like to replicate on a newly-purchased phone. The app also lets you DropShip the settings, sharing them with other Android or iOS devices.

Home Up

Home Up's Share Manager function is awesome for cleaning up your share menu.
Home Up adds customization settings for One UI’s launcher. You can change minor things like grid size, app drawer grid size, and even change the amount of blur you see when opening the app drawer. There is a separate section for folder customizations and a backup and restore option.

The coolest part of this one is the Share Manager section. It lets you customize the default share menu to include or not include whatever apps you want or don’t want. This saves a ton of space since you can select the apps you want to share from. You can also disable the Nearby Share function, giving you even more space.

Keys Cafe

When was the last time you saw official OEM support for the Dvorak keyboard?
Keys Cafe gives you a lot more options for the stock Samsung Keyboard. You can change the layout to Dvorak or Colemak if you want, and there are even a couple of symbols keyboard options. However, the big story here is the style section. You can change the keyboard color independent of the theme. Some truly delightful keyboard effects flood the keyboard with color as you type. There’s also an option to set different key sounds for backspacing or when typing text.

With Samsung’s keyboard, you can also play some typing games to improve your speed and accuracy. The games are very reminiscent of the kind I used to play when I took typing class in high school.


LockStar from Good Lock
Joe Hindy / Android Authority
You can tap and drag every element of the lock screen except the fingerprint scanner graphic.
LockStar lets you lightly customize your lock screen. It gives you a WYSIWYG editor, and you can move the elements around as needed. You can edit both the portrait and landscape lock screens at your leisure. Some of the things you can do are being able to move the existing elements around, change the wallpaper, change the clock, and add additional items like app shortcuts. It’s fairly easy to use overall. An auto-layout feature also moves stuff around how Samsung thinks it should be.

MultiStar brings buffs to the multitasking capabilities of Galaxy phones. While this module is useful on traditional phones, it is indispensable on foldables.

There is a dizzying number of settings you can tweak here. The module lets users configure the launch of the Multi window functionality, and tweak foldable-specific multitasking features, like opening full-screen apps on the foldable screen, and continuing those apps on the cover screen when the device is folded once again. You can also set aspect ratios for each app.

For those who don’t have a foldable but use Samsung DeX, there are customization options for you, too. You can force DeX to run in higher resolutions, allow more than five apps to run simultaneously on the connected display, or auto-open the last app you used on your phone on DeX.

Other MultiStar options let users quickly launch Multi window by holding the Recents key, prevent apps that lose focus from stopping, and fine-tune the size of the Multi window’s popup.

You can change the appearance of your navigation bar with NavStar.
NavStar lets you customize the soft key navigation bar or your swipe gestures, depending on which one you use.

For soft keys, you can change the look, add a button to hide the navigation bar at will, and change the background color and button layout. For swipe gestures, it’s more of the same. You can independently change the back gesture sensitivity from both sides of the screen, change the color of the line on the bottom, and make the bottom handle line transparent.

Nice Catch

Everybody who uses Good Lock should use Nice Catch.
Nice Catch is a surprisingly helpful tool. It creates a log every time your phone beeps, boops, vibrates, rings, wakes up, and every time you change your settings. However, the part we like the most is its log for toast notifications (the little bubbles that appear at the bottom of your phone occasionally). You can check these logs by entering the Nice Catch app and clicking on the appropriate category. You can also hit the three-dot menu and sort alphabetically to see how many instances each app did each thing.


NotiStar from Samsung Good Lock
Joe Hindy / Android Authority
NotiStar is great if you need to filter notifications or prevent apps from sending notifications.

NotiStar initially focused on notification management, but since Android 11, it has primarily evolved to focus on notifications history. You can select the apps you want notifications from or blacklist the ones you don’t. Additionally, you can add a filter that includes things like keywords as well as apps. For instance, you can get SMS notifications only if they contain the word “emergency.” You can also set this to work on the lock screen, and it’ll store notifications indefinitely or for as little as a week.

One Hand Operation+

You can actually use these gestures with the 3-button navbar, resulting in tons of functionality.
One Hand Operation+ introduces an experimental gesture control system that is fully customizable. You get a total of six actions (three on each side). The really cool part is you can keep the soft key navigation bar enabled, and this will give you some extra swipe gestures for other various things. This one has a bit of a learning curve, but the module does a decent job of letting you customize everything.

Each side is configurable with three different swipes (swipe out and up, swipe out and down, and the regular swipe out) for six configurable gesture shortcuts. You can set them to the usual home, back, and Recent Apps. Some additional options in this Samsung Good Lock module include closing an app, turning the screen off, taking a screenshot, showing/hiding the navigation bar, opening the notification panel, opening the menu, going forward (in the browser), and turning on the flashlight. The module also recently received a Quick Launcher option, which produces a popup of an editable list of essential apps.

The simplified Air Command menu and heart pointer make this one worth it.
Pentastic gives you a couple of extra options for the S Pen. It has a couple of extra cursors, including an arrow and a heart shape. There is also an extra sound when you use the S Pen, an extra shortcut that opens an app, and a simplified Air Command layout.

This is only useful if you have a phone or tablet with S Pen. I tested this with a Samsung Galaxy Note 20 Ultra, but those with regular Galaxy S series devices probably won’t need this.


Joe Hindy / Android Authority
This setting lets you choose whether to see notifications or the quick settings.
Although QuickStar doesn’t let you customize the quick setting theme anymore, since Theme Park mostly handles that, the module focuses mostly on status bar customizations.

You can add or remove icons from the status bar as needed. I removed the alarm clock icon during testing since I don’t need it there. There is also a mechanism to open the quick settings directly, skipping the notification shade in the process. Those are the two big things QuickStar does, and it’s relatively easy to customize.


Samsung Good Lock RegiStar
Ryan Haines / Android Authority

RegiStar’s functionality isn’t initially obvious, but it’s a surprisingly powerful tool once you understand its abilities. In short, it allows you to configure the Settings app, the search functionality in the Settings app, and launch user-configured features through the side key, by tapping the back of the phone (Back-Tap), or a firm screen press (Force-Touch).

Those who often hunt for settings or resist using the search functionality in the Settings app will like the menu customization features. You can order the menu how you like and choose to hide menu items. Minor items, including displaying a Samsung account nickname or full name or hiding the associated email address, also features.

Finally, what’s also quite helpful is the Settings change history feature. Tap this to display all your recent settings changes. This is great if you’re experimenting with tweaking your phone but can’t remember which setting you last adjusted. RegiStar will display these changes for you and make it much easier to revert.


Samsung Good Lock Routines Plus
Ryan Haines / Android Authority

Routines+ adds more functionality to Bixby Routines, from new macros to contextual triggers. For instance, this module lets you create a routine of a series of touch actions. Don’t see how this could be useful? You could create a macro that automatically checks for Galaxy Store updates or one that automatically opens a sales page of a retailer in your browser. The options are as extensive as your imagination.

You can also activate one of Samsung’s readymade routines, including converting the S Pen into a physical arrow key, or getting an audible alert when your battery is low.

This module adds a new Settings menu called Modes and Routines, through which you can access all the routines you’ve created.


Joe Hindy / Android Authority
SoundAssistant has a lot of power, but only for niche use cases.
SoundAssistant brings a host of customization options for your phone’s audio. You can use it to theme your volume panel, change the step volume for more granular volume changes, and even select which apps can (and can’t) play audio simultaneously.

The cool part starts further down the menu. The Bluetooth Metronome feature helps you sync your Bluetooth headphones with a video reference to minimize audio lag with Bluetooth headphones. It also lets you do things like reverse stereo sound (so left comes out of right and vice versa), change the sound balance, and even drop the phone into mono audio mode.

Theme Park

Theme Park
Joe Hindy / Android Authority
Theme Park has a learning curve, but custom themes are always awesome.
Theme Park lets you create your own custom theme. It asks you to select an image from your gallery, download folder, or any other album. From there, it lets you select a main color and uses the other colors from the image as accent colors. It also includes dark mode support, independent of the light mode version. You enable dark mode in the settings to get the dark mode version of any theme you make with Theme Park in Samsung Good Lock. Once done, it creates the theme with your selected colors and wallpaper. The app diverts you to the theme store to enable it.

Wonderland seems simple at first but you can actually do a lot with it.
Wonderland is a live wallpaper creator. There are a few presets so you can understand how everything works. However, the fun part is making your own. You can select a base image, other images to lay over the top, various effects, and even text. There are some movement effects as well as some particle effects as well. This one takes a while because you build this thing from the ground up, but the results can look pretty good if you have the right graphics and some patience.

Samsung Good Lock availability

The new animated menu makes Good Lock look way more polished than last year.

One of Good Lock’s biggest cons is its limited region availability. While you can technically download the app and its separate modules in any country through an APK repository, the app is not officially supported everywhere. It’s also worth noting that Good Lock is unavailable through the Google Play Store.

How to download and install Samsung Good Lock

Samsung Good Lock Galaxy Store listing

You can download and install Samsung Good Lock like any other app in a supported country.

To install Good Lock on your phone:

  1. Open the Galaxy Store app.
  2. Search for Good Lock. The icon resembles four interlinked puzzle pieces.
  3. Tap Install to begin the installation process.
  4. Once the app is installed, tap Open.

However, that is not the entire process. As described above, Good Lock has several modules, and each module is its own app. Thus, when you open the app and tap the install button alongside a module, you’ll be redirected to the Galaxy Store to install that particular module. There are 20 modules, so be prepared to jump to and fro quite often.

There is a positive here, though. You can uninstall or skip the modules you don’t intend to use. It saves space and lets you customize only what you want to customize.
