Can't rate samsung calendar itself, so I will say here that I am frustrated that Samsung is forcing its products to be used. I choose to use Outlook, yet I can't delete Samsung calendar or stop Samsung calendar from duplicating notifications etc. And as Outlook is dynamic and up to date, and Samsung calendar not, the notifications from Samsung calendar are out of date and just frustrating to the user. SAMSUNG PLEASE LET THE USER CHOOSE WHICH APPS THEY WANT TO USE
