So if your thinking of trying the One Ui 8 beta bare in mind that if you decide to leave the beta program it takes about 3 hours to downgrade and setup your phone again. It did for me anyway. Smart switch downloaded One Ui 7 quick enough but then said downloading again which I presumed meant downloading it onto my phone which took over an hour. Then had to restore my backup then messing about signing in to various apps. Then ended up having to reset my watch to get it to pair again and then set the watch up again.
