Samsung continues to redefine personalization for tech enthusiasts in 2026, pairing the new Galaxy S26 Ultra smartphone with the Galaxy Book6 Ultra laptop to deliver unmatched user control and flexibility. With the latest updates to One UI and the QuickStar module, Samsung empowers users to fine-tune their devices like never before, offering a highly customizable interface that adapts to individual preferences and enhances the overall digital experience.

Enhanced Quick Panel Customization

The newly released QuickStar update, version 10.0.04.26, brings long-awaited customization features to Samsung Galaxy devices. Users can now set custom backgrounds for multiple Quick Panel elements such as brightness sliders, volume controls, media players, and button panels. Previously, these options were limited or unavailable, but the latest update allows users to personalize their device interfaces using images from their gallery or other compatible apps, adding borders and unique backgrounds for individual quick settings buttons.

Flexible Layout Adjustments

This update also introduces greater control over panel layouts. Quick Panel elements can be resized, allowing widgets like the media player to occupy smaller portions of the screen. Additionally, brightness and volume sliders now have visible numeric values, although the font color remains fixed in black. Users can also adjust Quick Panel arrangements specifically in landscape mode, optimizing usability for various orientations.

Device Compatibility and Beta Programs

The enhanced QuickStar features are fully available on devices running One UI 8.5, including the Galaxy A37, Galaxy A57, Galaxy S26, Galaxy S26+, and Galaxy S26 Ultra. For those enrolled in the One UI 8.5 beta program, the updated QuickStar app extends to the Galaxy S24 and S25 series, as well as the Galaxy Z Flip 6 & 7 and Galaxy Z Fold 6 & 7, though availability depends on regional beta participation.

Expanding Creative Possibilities

With these updates, Samsung is not just improving functionality—it’s giving users creative freedom. By allowing individualized customization of UI elements, Samsung ensures that the digital experience is as personal as a desktop setup or a gaming rig, bridging the gap between mobile convenience and professional-grade control. Users can craft an interface that reflects personal style while optimizing workflow efficiency.

What Undercode Says:

Elevated User Personalization

Samsung’s latest QuickStar update demonstrates a significant leap in device personalization. Unlike previous iterations, this update allows users to fully control the aesthetics and functionality of the Quick Panel, ensuring that the device feels truly personal rather than generic.

Practical Implications for Daily Use

Resizing widgets and displaying slider values may seem minor, but these changes have practical benefits. For instance, quickly referencing volume or brightness levels without guessing improves efficiency, especially for professionals or content creators using Samsung devices as multitasking tools.

Strategic Device Support

By limiting full compatibility to One UI 8.5 devices while including beta program participants, Samsung ensures a controlled rollout that balances innovation with device stability. This strategy minimizes bugs while gradually exposing advanced users to new features.

Creative Expression Meets Functionality

Allowing users to assign backgrounds and borders to individual buttons transforms the Quick Panel from a simple utility interface into a canvas for self-expression. This approach may appeal strongly to younger users or designers seeking both utility and aesthetics in their tech.

Market Positioning

Samsung strengthens its position as a leader in customizable interfaces. This differentiates Galaxy devices from competitors, particularly Apple, where UI flexibility is relatively limited. The update aligns with trends emphasizing personalization as a key factor in consumer choice.

Ecosystem Integration

These updates encourage deeper engagement with Samsung’s ecosystem. By linking smartphones to laptops like the Galaxy Book6 Ultra, users experience consistent design and usability improvements across devices, enhancing brand loyalty and cross-device productivity.

Potential for Third-Party Development

The expansion of QuickStar customization opens doors for third-party app developers to create compatible assets, wallpapers, or themes, potentially fostering a small ecosystem around One UI customization.

User Experience Considerations

While improvements are substantial, some limitations remain, such as the inability to change slider font colors. Addressing these minor constraints could further solidify Samsung’s reputation for a truly user-centered interface.

Future Updates and Expectations

The beta program suggests Samsung is actively testing additional features. Future updates may extend QuickStar functionalities beyond current devices, potentially introducing dynamic or AI-driven panel adjustments that respond to user habits.

Competitive Advantage

By pushing customization to new heights, Samsung offers a tangible advantage over other manufacturers. Users choosing Galaxy devices gain both technical power and aesthetic control, appealing to both tech enthusiasts and professionals seeking workflow efficiency.
