Samsung’s highly anticipated new software interface, One UI 9, with its Android 17-based structure, has been viewed in detail for the first time on the Galaxy S26 model. The preliminary review conducted by the SamMobile team reveals the innovations and interface changes that Samsung will offer to users with its next major update package.

This leaked build, which is still in the development phase, carries important clues regarding the company’s strategic transformation in terms of design language and artificial intelligence integration. Users have the opportunity to experience visual improvements as well as new control mechanisms that increase functionality in this version tested with the Galaxy S26.

• The thickness of the brightness and volume sliders on the quick panel has been significantly increased in the One UI 9 interface.

• A new feature offering artificial intelligence-supported automatic creative visual transformation suggestions has been added to the Photo Assist tool.

• The Audio Eraser tool has now gained a central management menu for all supported applications.

• An improved control option for auto-hiding the taskbar in the Samsung DeX interface has been included in the system.

Visual Changes Are Being Made in Interface Design

The first change users will notice in the new One UI 9 version will be the updates made to the size of the sliders in the quick panel. The volume and brightness adjustment bars in the quick access menu have gained a more prominent and thicker design compared to previous versions.

While this change aims to increase one-handed use ergonomics, it takes the overall user experience to a more modern look. Samsung is making all control elements more accessible in order to increase visual aesthetics.

Artificial Intelligence Supported Tools Are Being Developed

Artificial intelligence, one of the focal points of the update, has been strengthened in basic tools such as Photo Assist and Audio Eraser. While Photo Assist now analyzes photos and offers creative editing suggestions to users, audio-focused editing tools have also been made more functional with application-based customizations. Being able to manage these tools from a central menu, especially for video content creators, will significantly speed up the workflow.

System Efficiency and DeX Performance Are Being Increased

The new update offered for Samsung DeX users makes the hiding behaviors of the taskbar and status bar more flexible. This setting provides a more central control point for users who want to personalize their desktop experience. The overall stability of the software and the optimizations offered by Android 17, the operating system base, promise a fluid performance for Galaxy S26 users.
