You must first withdraw your enrollment through the Samsung Members app on your device, and then you may need to roll back your software using a computer with the Smart Switch program.
1. How to Withdraw your Enrollment of Beta Program
Open the Samsung Members app on your Galaxy phone.
Go to the Discover tab (or the home screen where you see the beta banner).
Tap on the One UI Beta Program banner or notice to enter the beta section.
Tap the More menu (three vertical dots) in the top-right corner.
Select "Withdraw from Beta Program" or "Beta program settings" > "Withdraw".
Follow the on-screen prompts and tap "Leave" or "Withdraw" to confirm your decision.
2. How to Rollback Software through Smart Switch Program.
Install Smart Switch on your computer from the official Website.
Connect your Galaxy phone to your computer using a USB cable.
Launch the Smart Switch application on your computer.
The Smart Switch program should recognize your device is running a beta version and display a "Downgrade" or "Revert" option (users on a stable version will see an "Update" button instead).
Click "Downgrade" and follow the on-screen instructions to begin the rollback process.
Once the process is complete, your device will reboot into the official, stable OS version, and you can then restore your backup data.
Important Notice : This process will factory reset your device and wipe all locally saved data. Be sure to back up all your important data (photos, contacts, messages, etc.) using Smart Switch on your computer before starting the downgrade process.
