Galaxy S9, S9+, and Note 9 Receive Samsung’s Latest One UI 7 Update via Leaked Custom ROM
Samsung’s Galaxy S9, S9+, and Note 9 may be aging devices, but thanks to the modding community, they are receiving a breath of fresh air. A leaked custom ROM by the developer XRom brings Samsung’s latest One UI 7 to these flagship devices, originally launched with One UI 1.0.
One UI 7 on Exynos 9810-Powered Devices
This custom ROM enables One UI 7 features on Samsung devices powered by the Exynos 9810 chipset, including:
- Revamped UI and animations
- New Samsung apps from One UI 7
- Privacy and security enhancements
- Performance optimizations
- AI-powered features previously limited to newer models
This means Galaxy S9, S9+, and Note 9 users can now experience software updates that were officially never meant for these phones.



Bugs and Known Issues
Since this is an unofficial port, the ROM does come with a fair share of bugs. Users have reported issues with:
- Audio problems
- Brightness control (though a fix is available)
- Video playback glitches
- Camera malfunctions
- Potential other bugs affecting usability
Despite these issues, early testers report a mostly stable experience with the ROM, and the developer is actively working on fixes.
Should You Install It?
If you’re comfortable with custom ROMs and understand the risks, this One UI 7-based ROM is a great way to modernize your device. However, it’s recommended to wait for further refinements if you rely on your phone for daily use.
How to Install
Installation requires TWRP recovery and an unlocked bootloader. Ensure you follow the developer’s instructions carefully, make a backup of your data, and flash the ROM accordingly.
Final Thoughts
While Samsung has long ended official updates for the Galaxy S9, S9+, and Note 9, the developer community continues to breathe life into these phones. With One UI 7 now unofficially available, these 2018 flagships can enjoy Samsung’s latest software features from Galaxy S5 well into 2024.
