Theming Your Samsung Device with Good Lock
Back in 2016, Samsung introduced Good Lock, marking a significant shift in the level of customization available on its phones compared to other Android brands. Good Lock offers various tools, enabling users to personalize their Galaxy smartphones extensively.
This feature, among others, has contributed to Samsung's reputation for producing top-notch Android devices, known for their unique and customizable nature both internally and externally.
As time has passed, Good Lock has continued to introduce additional modules, giving you the ability to create personalized phone themes, customize always on display clock style and modify nearly every aspect of the One UI interface. If the default color scheme of your Galaxy S21 doesn't excite you, you can bypass Samsung Themes and customize it to reflect your style!
Here's a guide on customizing your Galaxy using Samsung Good Lock.
Creating a system theme using Theme Park
It offers extensive coverage of the system and surpasses the quality of the majority of themes available in Samsung Themes. With Theme Park, you can design a personalized theme using your wallpaper or hex code colors.
You have control over everything from the main colors to accents and notifications. For many users, Theme Park is the most essential feature of Good Lock.
I wish it were easier to learn, but don't stress—I'll walk you through it.
First, get Good Lock from the Galaxy Store, not Google Play, where many fake versions lurk. Then, download Theme Park from the Galaxy Store. Next, open Good Lock from your app drawer and select “Family” from the bottom tabs. Finally, tap on “Theme Park” and hit “Start” to begin.
Tap “Allow” and then tap “Create New.” Since Theme Park doesn't work with live wallpapers, you'll have to choose a static one. Select the image you want for your wallpaper and adjust the edges as needed. After you're done, tap “Done.” Once your static wallpaper is set, tap “Next” to proceed.
If the preset colors don't suit your taste, choose the Right Color Sample with the pencil icon to input a custom hex color. At first, it appears as a black/white gradient until you adjust the Saturation.
To select a different main color, tap the Left Color Sample and repeat steps 11 and 12 until you find your desired color. Finally, tap the pencil icon above the secondary palettes to customize your style's colors.
To alter a style element's color, tap on it. Then, slide the Saturation slider towards the right to switch from grayscale to RGB. Choose the color you want, and tap “OK” to confirm.
To leave this color menu, tap the checkmark. Next, select the App Icons screenshot, which is the second one in the top row. You don't have to adjust the colors for every screen or menu, but I suggest experimenting with the app icons and the Quick panel colors. Finally, tap the blank color bubble above “Icon color.”
To transition from grayscale to RGB, slide the Saturation slider towards the right. Then, select the color you desire and tap “OK” to confirm.
Swipe left twice to access the Quick Panel color picker. Then, lower the Blur level slider to reveal more detail from your wallpaper. You'll find various color elements to adjust, including Active and Inactive Quick Toggle Icon Colors, Active and Inactive Quick Toggle Background Colors, Notification Text Color, Notification Card Color, Notification Category Text Color, and Quick Panel Background Color.
Move the Saturation slider to transition from grayscale to RGB, choose your preferred color, and adjust the Transparency slider for the desired opacity. Finally, tap “OK” to confirm. Repeat these steps for each color element as needed.
After adjusting the colors to your satisfaction, return to the theme overview screen by using the back button on your navigation bar or performing a back swipe gesture. Then, toggle dark mode on by tapping the sun icon located in the top right corner.
If you wish, repeat steps 11-31 to customize the Dark mode of your theme. Finally, tap the Download icon in the top bar to name and export your completed theme. Enter a name for your theme, ensuring it doesn't contain spaces or special characters and stays within the 20-character limit, then tap “OK” to confirm.
Once the theme is generated, you'll be redirected to your list of created themes. Select your newly named theme, then tap “Apply” to implement it.
While it might seem like a lengthy procedure, believe me, the effort pays off in transforming your phone's appearance into something truly amazing. I've spent countless hours immersed in Theme Park—even while waiting in line at actual theme parks—because it's an excellent way to pass the time.
Simply opting for the default color palette based on your wallpaper can already provide a significant enhancement over the standard white theme. You can also get your hands on Samsung s20 ultra wallpaper for your android phone that has caught everyone's attention.
Explore the remaining features of Good Lock.
This is merely the start of your journey into a vast and intricate world. Good Lock offers over a dozen add-ons for fine-tuning various aspects, such as customizing which icons appear in your status bar with QuickStar, crafting a personalized navigation bar with NavStar (especially useful if you're still using the three-button navigation instead of gestures), and creating your own motion wallpapers and one-handed modes. Users often have question why is my back button not working on my Samsung? There can be plenty of reasons for that and many easy solutions too.
There's plenty to delve into on your Samsung Galaxy device. While we provide an easy-to-reference guide to Good Lock's various sections, there's also merit in downloading individual modules to discover their capabilities firsthand.
