Samsung is developing its tenth major mobile software iteration, One UI 10, built on the Android 18 platform and projected for release in 2027, according to industry reports. The milestone update aims to introduce significant design overhauls and advanced agentic artificial intelligence capabilities across Galaxy smartphones, foldables, and connected ecosystems, based on regional technology disclosures.
Android 18 Foundation and Expected Release Timeline
The upcoming software package will serve as the successor to One UI 9. According to industry roadmaps, Samsung plans to initiate a beta program for One UI 10 in May 2027, followed by multiple trial builds. A stable commercial rollout is anticipated in July or August 2027, launching first on the Galaxy Z Fold9 and Galaxy Z Flip9 before expanding to older hardware.
Support is expected to span a broad catalog of hardware, including the Galaxy S26, Galaxy S25, Galaxy S24, and Galaxy S23 lineups. Foldable devices starting from the Galaxy Z Fold5, select Galaxy A-series phones, various Galaxy Tab models, and specific Galaxy M and F variants are also slated for the upgrade. For devices like the Galaxy S23, Galaxy Z Fold5, Galaxy Z Flip5, and Galaxy Tab S9 family, this version will mark their final major Android OS upgrade.
Fluid AI Design System and Visual Overhaul
Samsung intends to incorporate elements of its Fluid AI Design System, a concept that earned a Red Dot Design Award in 2026. Rather than relying on static menus, the updated interface design utilizes translucent glass-like surfaces, floating elements, and dynamic animations that adapt to user activity. Visual cues such as magnetic animations and lighting effects indicate when background agents collect data or process multi-step instructions.
A central feature of this design direction is a floating, spherical AI assistant capable of traversing different areas of the interface. This agent aims to assist with cross-application tasks such as calendar searches, route planning, and simultaneous multi-device actions.
Agentic AI Integration with Galaxy AI and Gemini
Expanding on existing frameworks, One UI 10 deepens the integration of Galaxy AI and Google Gemini. Unlike traditional assistants limited to answering isolated queries or summarizing text, the system incorporates agentic capabilities designed to execute autonomous, multi-step workflows. Users could theoretically organize an entire trip with a single prompt, prompting the software to locate venues, populate calendar schedules, and trigger navigation.
To maintain user trust, Samsung builds upon the AI Activity logging interface introduced in One UI 9. The new version will expand transaction logs to provide clear visibility into background operations, addressing data privacy and security requirements.
Ecosystem Connectivity and Device Optimization
Beyond artificial intelligence enhancements, the software update targets broader system improvements. Samsung is refining customisation options, system apps, widgets, Samsung DeX features, and Secure Folder protections. Optimization efforts also focus on larger screens and foldable form factors, improving multitasking efficiency on devices like the Galaxy Z Fold series.
Integration extends beyond smartphones to encompass the wider Galaxy ecosystem, which includes the Galaxy Ring, Galaxy Watch series, smart glasses, and the Galaxy XR headset. While these accessories gain tighter interoperability, Galaxy smartphones remain the central hub for the connected ecosystem.
