S7 Calendar limitations ?

[AC Question]

On my S4 I could see Day or Week or Month calendars w/my Tasks or To Do lists. The S7 calendar is not intuitive - I entered a task and then couldn't find it ! Do I have to link to a calendar on some other device. I want to just have my calendar on my phone. I am so unhappy w/this feature thar I am thinking of returning he phone.
