Samsung is beginning to roll out One UI 9 to older models of its Galaxy smartphones, including the Galaxy S24. This update is based on Android 17, the latest version of the Android operating system, and includes a variety of improvements. It is now being released in its final form on an increasing number of Samsung tablets and smartphones. Following the Galaxy S26, which received the update at the start of September, and the Galaxy S25 and last year's foldable models, the 2024 devices are now being targeted. In South Korea, the major update is being deployed on the Galaxy S24 series, as well as the Galaxy Z Fold 6 and Galaxy Z Flip 6. The rollout in the rest of the world, including Europe, is expected to proceed without significant delays. Users who have already installed the beta version of One UI 9 may only need to download around 500 MB of data to upgrade. For others, the update is expected to take approximately 3.8 GB of data, so it may be wise to free up storage space beforehand. In addition to the features included in Android 17, One UI 9 introduces more personalization options. These include a more customizable shortcuts panel, the ability to create personalized Now Brief cards, and additional AI tools such as FanCam, which can automatically capture and save moments from videos. Samsung has long been known for its generous software support, and recently, the company has committed to providing up to seven years of Android updates and security patches for its devices. This ensures that even older models remain secure and up to date with the latest features. As One UI 9 becomes more widely available, users can look forward to enhanced functionality and a more tailored experience on their Samsung devices.
