Follow these steps to check for and install the One UI 9 update on your phone:

Why Has My Galaxy Phone Not Received One UI 9 Yet?

If your Galaxy S25 Ultra or another eligible phone does not display the One UI 9 software update today, it does not mean your device is unsupported. Regional firmware scheduling and carrier testing schedules regularly influence release timelines.

Consider the following factors that affect software availability:

• Staggered Regional Deployments: Samsung releases update packages in geographic batches to ensure server stability and monitor initial system feedback.
• Carrier Certification Process: Network-locked phones often require carrier-specific certification before the update file is released to end users.
• Internal Storage Space: Ensure your phone has sufficient clear storage space, as major operating system updates require several gigabytes to unpack and install successfully.
