Thank you for your inquiry regarding One UI 8.5 on your Galaxy S25 Ultra.
Please note that the stable One UI 8.5 update has not yet been fully released to all Galaxy S25 Ultra devices. At the moment, Samsung has been running a beta testing program for the Galaxy S25 series, and the stable version is expected to be released after the testing phase is completed.
To check if the update is available on your device, please follow these steps:
Go to Settings.
Tap Software update.
Select Download and install.
If the update does not appear yet, this means it has not been rolled out to your region or device at this time. Samsung releases updates gradually by region and device configuration, so it may take some time before it becomes available on all devices.
