Best One UI Customization Tips for Samsung Galaxy Phones

I still remember helping a friend customize a new Galaxy phone after they switched from an iPhone. Within a few minutes, they were surprised by how much Samsung allowed them to change—from the lock screen and navigation gestures to custom themes and advanced shortcuts. What stood out most was that many of the best customization tools were already available through One UI and Samsung's Good Lock platform, yet most Galaxy owners had never heard of them. If you want to make your Samsung phone look, feel, and work exactly the way you want, these customization tips can completely transform your experience.

Quick Answer

The best One UI customization tips include installing Good Lock, using Home Up for home screen personalization, LockStar for lock screen customization, Theme Park for custom themes, NavStar for navigation controls, and One Hand Operation+ for gesture shortcuts. Samsung's latest One UI 8 and One UI 8.5 updates add even more personalization options, making Galaxy phones among the most customizable smartphones available in the United States.

Why This Matters

Customization is not just about appearance. The right One UI settings can improve productivity, reduce screen clutter, speed up navigation, enhance accessibility, and make daily tasks faster. Many Galaxy users focus only on wallpapers and themes while overlooking customization features that can significantly improve usability, efficiency, and overall satisfaction with their devices.

Why One UI Is One of the Most Customizable Android Interfaces

Samsung has spent years refining One UI into one of the most feature-rich Android experiences available. Unlike many Android skins that offer limited personalization, One UI allows users to modify nearly every aspect of the interface.

Whether you own a Galaxy S25 Ultra, Galaxy S24 Ultra, Galaxy Z Fold, Galaxy Z Flip, or a Galaxy A-series device, Samsung provides extensive customization tools through both native settings and Good Lock modules.

One UI 8 and One UI 8.5 continue this trend with improved lock screen editing, smarter widgets, Quick Panel customization, AI-powered personalization, and deeper integration with Samsung's customization ecosystem.

Install Good Lock Before You Start

If there is one recommendation repeatedly shared by Samsung enthusiasts and Reddit communities, it is this: install Good Lock first.

One of the most common complaints among Galaxy users is that Samsung does not prominently advertise Good Lock. Many users own Samsung devices for years before discovering its capabilities.

To install Good Lock:

Galaxy Store → Search "Good Lock" → Install

Once installed, you'll gain access to multiple modules that unlock advanced customization features unavailable through standard One UI settings.

Good Lock Module	Main Purpose
Home Up	Home screen customization
LockStar	Lock screen editing
Theme Park	Custom themes and icons
NavStar	Navigation bar customization
ClockFace	Custom clocks
Wonderland	Animated wallpapers
One Hand Operation+	Advanced gestures
Sound Assistant	Audio customization
MultiStar	Multitasking enhancements

Customize Your Lock Screen with LockStar

LockStar gives you complete control over your lock screen layout.

With LockStar you can:

• Move the clock anywhere

This is especially useful for Galaxy S25 Ultra and Galaxy Z Flip users who want faster access to frequently used features.

Create Your Own Samsung Theme with Theme Park

Theme Park allows you to build custom themes without needing third-party launchers.

You can customize:

• System colors
• Icons

Many competing guides only discuss downloadable themes. Theme Park allows you to create a personalized visual identity that matches your wallpaper and preferences.

Redesign Your Home Screen Using Home Up

Home Up is consistently one of the most recommended Good Lock modules in Samsung communities.

Features include:

• Custom folder layouts

DIY Home Screen has become particularly popular among One UI 7, One UI 8, and One UI 8.5 users who want desktop-like flexibility.

Customize Samsung Navigation Gestures with NavStar

Many Galaxy owners dislike default navigation layouts after major One UI updates.

NavStar allows you to:

• Modify navigation buttons

Galaxy Z Fold and Galaxy Z Flip users often use Wonderland to take advantage of larger displays and cover screens.

Improve One-Handed Use with One Hand Operation+

One Hand Operation+ is arguably one of Samsung's most underrated tools.

After enabling it:

Good Lock → One Hand Operation+

You can assign gestures for:

• Back
• Home
• Recent apps
• Quick tools
• Screenshots
• Split screen
• Notifications

This feature dramatically improves usability on large phones like the Galaxy S25 Ultra.

Customize Your Always-On Display

The Always-On Display offers more personalization than many users realize.

Settings → Lock Screen and AOD → Always On Display

Customize:

• Clock styles
• Brightness
• Notification icons
• Display schedules
• Widget visibility

ClockFace expands these options even further through Good Lock.

Build Smarter Widgets for Productivity

Samsung's Smart Widgets allow multiple widgets to occupy the same screen space.

Popular combinations include:

• Weather + Calendar
• Calendar + Reminders
• Battery + Device Care
• Samsung Health + Weather

One UI 8 introduces improvements to adaptive widget behavior and personalization.

Personalize the Quick Panel

One UI 8.5 places greater emphasis on Quick Panel customization.

Swipe Down → Edit Quick Panel

Recommended changes:

• Move frequently used toggles to the top
• Remove unused controls
• Prioritize Device Control
• Add Smart View
• Add Modes shortcuts

This simple adjustment can save countless taps every day.

Automate Your Galaxy Phone with Modes and Routines

One of Samsung's most powerful customization tools is Modes and Routines.

Settings → Modes and Routines

Create automations such as:

• Work mode
• Driving mode
• Sleep mode
• Gaming mode
• Battery-saving schedules

Many users overlook this feature despite it being one of the most practical customization options available.
