Users of the Galaxy S23, Galaxy S23 Plus, and Galaxy S23 Ultra in India can now install the One UI 8 beta on their devices. The build number for that software is S91xBXXU8ZYHB, and it’s a 3.1GB download that includes the September 2025 security patch, according to Bloomberg Tech.

The downloads are smaller for other devices, and the regional restrictions are different, at least for now. The Galaxy A36beta build is about 2.1GB and is available in the US, the UK, South Korea, and India. The build for the Galaxy A55 is 1.9GB, and it should be available in the same regions as the Galaxy A36.

To get access to the One UI 8 beta, you need to log in to the Samsung Members app and register for beta access with your eligible device. Once you’ve done that, the update will appear in the Software Update section of your phone. Samsung should expand beta access to even more devices this month, including the Galaxy Z Fold 5 and Z Flip 5, but there’s no information about their updates yet.
