What’s New in One UI 9.0?
Built on top of Android 17, One UI 9.0 promises a smoother, more intuitive, and highly personalized user experience. Here are some of the key highlights of the new update:

How to Download and Install One UI 9.0
If you own an eligible Galaxy smartphone, you might receive a notification once the update is available in your region. However, you can also check for it manually by following these simple steps:
- Open the Settings app on your Galaxy device.
- Scroll down and tap on Software update.
- Select Download and install.
If the update is available, follow the on-screen prompts to download and install the firmware. Note that the update size can be substantial (for instance, it is around 3.4GB for the Galaxy S25 Edge), so it is recommended to download it over a stable Wi-Fi connection and ensure your device is adequately charged. Samsung also advises backing up your personal data before initiating the upgrade.
Phased Rollout Continues
Since software updates are released in phases, availability can vary by country, model, and network carrier. If you do not see the update immediately, there is no need to worry—regional software teams are staging the distribution to ensure platform stability, and your device should receive it soon. Older flagship models are also slated to receive the Android 17-based One UI 9.0 update throughout October 2026.
