Yes. You have to use smart switch on a PC to revert back to stock. You will have to unenroll from the beta from the members app first. Btw this is answered in the FAQ under Beta notices.
I did factory reset after updating Beta last night. I was unable to sign in my phone. Somehow my find my phone was turned off, so I couldn't unlock my phone from my S8 Tab. The beta was still. When I tried to sign in after reset, there was a message that someone was trying to factory reset my phone, and it asked for a password. It stoll would not take my password. Thankfully I could sign in with Gmail. I'm thinking I would like to get phone back without Beta.
You can deregister from the beta program from Samsung member’s app -> settings -> one Ui Beta program status -> Withdraw. Once withdrawn you can download smart switch on the PC and restore to Android 12. Please back up all data on your device before using smart switch to move back to Android 12 as this does reset the phone. if you do choose to move to Android 12 , we suggest you backup all your device data and master reset on Android 12 and try if for a few days. If issues are still not resolved, you always have the choice to withdraw and move back to Android 12.
