Do withdraw from Samsung one ui 6 beta program by using smart switch in your laptop/desktop.after successful withdrawal,you need to reconnect your mobile with your laptop or desktop.then you can download stable version of one UI 6.now you've to reconnect once again your mobile with your laptop or desktop when new security patch update releases.download it by using smart switch.this you have to do it one time after uninstallin beta program.after that you'll get proper security patch update regularly each month. I've experienced this problem and found a solution by my self.now I'm getting regular security patch updates without using smart switch.
