Hi @00700 Beta pretty stable for me and a number of other users. However some Members reported problems in rolling back after withdrawal (not on Smart Switch) , I assume they had issues. A problem with animations has been reported on one site https://www.sammobile.com/news/samsung-one-ui-5-0-animations-performance-needs-improvement/
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
My Device- S21 Ultra 5G ( SM-998B/DS ) CSC= BTU , 12GB/256GB
One Ui 5.0,Android 13 .
