Samsung One UI 8 Rollout: Smarter & Safer Galaxy
Samsung Electronics has officially begun the long-awaited rollout of One UI 8. The update, launched on 15 September 2025 with the Galaxy S25 series, will gradually expand to other popular devices in the coming months. Based on Android 16, this new interface is not just a routine upgrade — Samsung claims it brings a smarter, safer, and more personalised experience that takes Galaxy smartphones to the next level.
What’s New in One UI 8?
Galaxy AI and Personalisation
The most exciting aspect of One UI 8 is its AI-driven personalisation. This system goes beyond just changing apps or themes — it understands users’ daily routines and provides tailored suggestions.
- It automatically tracks schedules, traffic updates, and media preferences.
- Features like “Now Brief” and “Now Bar” are designed specifically for the Galaxy Z Flip series, offering real-time updates directly on the FlexWindow.
- Imagine your phone giving you traffic updates before work and setting alarms before meetings — One UI 8 makes that possible.
Security System: KEEP and Knox Matrix
Security remains a top priority, and One UI 8 strengthens this further.
- The KEEP system provides every app with separate encrypted storage. If one app faces a threat, other data stays completely secure.
- Knox Matrix monitors all connected devices within the Galaxy ecosystem. If one device is compromised, the others are immediately alerted.
- With Post-Quantum Cryptography (PQC), Samsung safeguards user data even on public Wi-Fi, protecting against potential future quantum computing attacks.
This advanced security makes Galaxy devices even more reliable, especially for users who work on public networks or own multiple connected Galaxy products.
Multimodal AI and Smart Features
Samsung has infused AI across One UI 8 to simplify user experience.
- With AI Results View, users can now display AI-generated results in split screen or floating windows, boosting workflow and multitasking.
- Gemini Live Voice Integration enables users to perform internet searches hands-free through FlexWindow using just their voice.
- Audio Eraser eliminates background noise in calls and video recordings, ensuring crystal-clear sound.
- Portrait Studio brings creative, professional-quality photo editing tools directly into the device.
Design and Customisation
Samsung’s focus on aesthetics continues with One UI 8, offering a more refined design experience.
- New wallpapers and clock designs adapt fonts and sizes based on faces or shapes in photos.
- Emoji Wallpapers for FlexWindow provide Galaxy Z Flip users with greater personalisation options.
One UI 8 enhances not only functionality but also creativity and style.
Eligible Devices
Samsung has released an extensive list of devices for the update, confirming that it will roll out gradually by October–November 2025.
- Galaxy S series: S25, S24, S23, S22, S21 FE
- Galaxy Z series: Fold6, Flip6, Fold5, Flip5, Fold4, Flip4
- Galaxy Tab series: Tab S10, Tab S9, Tab S8 series, including FE and Lite models
- Galaxy A series: A56 5G, A36 5G, A26 5G, A17, A07, A06, A55 5G, A35 5G, A25 5G, A16, A15 5G, A54 5G, A34 5G, A73 5G, A53 5G, A33 5G
Samsung confirmed that more than 51 Galaxy devices are on the priority list. However, not every feature will be available on all models, as some AI capabilities require newer hardware.
Global Launch Strategy
Samsung rolled out the update first for the Galaxy S25 series in Korea, the UK, and the US. In the coming weeks, the rollout will expand to India and other international markets.
The company continues its established strategy of launching updates on flagship devices first, followed by mid-range and entry-level models. This allows premium users to experience new features early, enhancing brand value while ensuring a gradual, stable expansion to the wider Galaxy user base.
Why One UI 8 Stands Out
The aim of One UI 8 goes beyond adding new features — it seeks to transform smartphones into a personal digital assistant.
- AI and multimodal interaction are redefining smartphones as lifestyle tools.
- Security enhancements assure users their data is safer than ever before.
- Personalisation and design upgrades make the experience both smart and visually appealing.
Conclusion
One UI 8 is set to redefine Galaxy devices. With multimodal AI, streamlined workflows, post-quantum security, and an enhanced design language, it prepares Galaxy smartphones for the future — today.
Galaxy users can head to Settings > Software Update to install the update and unlock a smarter, more secure, and more personalised experience with One UI 8.
