Unless The Cotswolds are no longer in the U.K.... I have been on Android 12, OneUI 4 beta for the last week...
Are you on the Samsung unlocked, (non carrier branded) CSC code, BTU?
To check your CSC code, go to...
Settings > About phone > Software information > Service provider software version...
@BashBashy Unfortunately does nee to be unlocked device with CSC code BTU.
@swills9 The 2nd Beta is only available for the S21 series at the moment.
@Tariq_786 Certainly there are some problems but experiences vary. The Beta on my device is pretty stable, though there is a bit of Battery Drain.
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
