I tried everything. If I add an event to my google cal on my computer it will show up on my Samsung S4 calendar but it won't sync if I add an event on the phone.
I still experience this issue. New phone, this is the worst issue I've experienced.With the information given here, <snip>
Like everyone else, I was unsuccessful in syncing calendar events on my S4 with my on-line Google calendar. I contacted Samsung directly and spoke with a senior tech, who quickly resolved the issue. He advised that this issue was fixed in late July, so if you're unsuccessful in syncing your phone's calendar with Google, contact Samsung tech support.
