How to Customize Your Samsung One UI Theme
If you own a Samsung phone, you may have noticed that finding a clean and attractive theme on the Galaxy Themes store can be a challenge. Many of the themes available are overly designed and cluttered. While there are alternative options like substratum themes, they often require root access and lack granular controls.
Luckily, creating your own theme for Samsung One UI is easier than you might think. There are two main methods you can use: Theme Park and Hex Tool. These tools provide different levels of customization and flexibility, allowing you to explore your creativity and design a theme that suits your style.
Theme Park
Theme Park is a Goodlock module developed by Samsung that simplifies the process of customizing your One UI theme. You can download it either from the Goodlock app or the Samsung Galaxy Store app. Since it's an official Samsung app, you can expect a consistent and polished result after applying the theme.
To get started with Theme Park, open the app and tap on the “Design new Theme” button. This will open your Gallery, where you can select wallpapers for your new theme. The app will automatically extract colors from the chosen wallpaper and allow you to select a primary color and style for your theme. By making just a few changes, you can completely transform the look and feel of your UI.
In addition to Theme Park, you can also use other apps from GoodLock like Lockstar, Clockface, and Task Manager for further customization. Lockstar allows you to change the lock screen designs, Clockface lets you customize clock designs, and Task Manager allows you to select different layouts for the recent apps panel. Each app has its own unique features and can make a significant difference when combined.
Hex Tool
If you're looking for more advanced customization options, Hex Tool is a great choice. This app is similar to Substratum but exclusive to Samsung smartphones. Unlike Substratum, Hex Tool doesn't require root access to install themes. You can find a wide range of themes to install or create your own from scratch.
To get started with Hex Tool, install the Hex Installer app from the Play Store. It's a paid app but offers a range of powerful features that make it worth the price. Once installed, you'll find two apps in your app drawer: #hex and #hexified. The #hex app allows you to edit and customize your theme, while #hexified acts as a store where you can find themes to install and plugins to help you edit your theme.
With Hex Tool, you can not only change colors but also design styles. There are minimal themes, themes that mimic stock Android, and themes that resemble UIs from other OEMs like MIUI. You can even create your own icon packs and wallpapers using Photoshop or download them from online sources. Additionally, you can change font styles, sizes, and even dimensions of the UI. These changes will be applied system-wide, including the quick setting panel, and can also be applied to third-party apps like WhatsApp and Twitter.
Customizing your theme with Hex Tool is simple. Just follow these steps:
- Download the Hex Installer app.
- Download a plugin of your choice from the #hexified_ app or the Play Store.
- Open the #hex_ app and select the plugin from the UI mode option.
- Tweak the coloring and preferences settings to your liking.
- Upload your own font styles and icon packs or download them from online sources.
- Select the third-party apps you want to apply the theme to.
- Click on Build and Install, which will take you to the Galaxy Themes app to install the theme.
If you're particularly proud of your theme, you can also share it with the Hex community.
Theme Galaxy
Another alternative to Hex Tool is Theme Galaxy. This app offers similar customization options, with the added ability to customize the keyboard, quick setting panel, and navigation bar separately if desired. Theme Galaxy also provides options to customize the always-on display and message bubbles, although these are pro features.
While Theme Galaxy offers a range of customization options, it can be more challenging to use compared to Hex Tool. It doesn't provide a preview of the theme before installation, so you'll need to install the theme to see how it looks. However, with some time and effort, you can achieve great results using this app.
In conclusion, Hex Tool is the most comprehensive tool for creating your own Samsung One UI theme. It offers a wide range of options and features, making it a powerful app for customization. Theme Galaxy is a good alternative but has some limitations. Samsung's Theme Park app is unique in that it adjusts the theme to suit your wallpaper, maintaining consistency for your device.
Whether you choose Theme Park, Hex Tool, or Theme Galaxy, you can unleash your creativity and design a unique theme that reflects your personal style. Take advantage of these tools to transform the look and feel of your Samsung One UI and make your phone truly yours.
