I downloaded the beta and backed up my phone through Samsung cloud. I didn't know that you should do it through Smart Switch. So my question is, if I withdraw from the beta will everything be erased?
I've heard you can't restore data backed up while you used the beta software..
You should've backed up before you installed the beta. You can however revert to any saved backup on One UI 3 or older.
But! You can backup your entire gallery to google photos for fairly cheap rates. That way you can revert and restore your photos that way and deal with settings manually.
under normal circumstances, it would work.. you would factory reset your phone.. and then load your backups off your Samsung cloud or wherever else you had it, you just wouldn't be using Smart switch. I cannot say if having downloaded the beta updates affects this process in any way. I would suspect if you can get your phone back to factory out of the box restored then you should be able to restore anything else from your backups not including smart switch. that's not a very good answer, just stuff to think about.
the main things to back up are contacts, documents and photos... almost everything else can be replaced. fresh installs for apps are cleaner than installs from backups. that way you don't import any bad settings from a backup.
It is not required to backup via smart switch , you are free to use any backup service to backup your data. When you do withdraw from beta and use smart switch to roll back to Android 11, your data on device is erased not from your cloud backup or any backup on PC.
