So I downloaded and installed the One UI 4.0 for my S21 ultra in October 2021. I haven't had an update or security patch since. I am concerned that I'm stuck on this Beta. I can't remove it. I have tried removing it through my PC on Smart Switch however, I getting an error message saying I don't have enough space on my harddrive however, I have gbs worth of space. I have tried withdrawing from the Beta programme on the Samsung Members however, I get a message saying it has ended. Can anyone help with this?
