Google calendar created on PC won't show on galaxy 4 active
I have the Verizon S4 and this is how you do it with that phone:


Open stock calendar app
Hit the left hand soft key for menu options
Chose Calendars from that list
All of your calendars should be listed there
Hit the Display option to choose which calendars you want to display all the time (All is also an option). Check All or select individual calendars.
