Google calendar notifications in double on Galaxy S3 I have used Calendar S, the stock calendar application on the Galaxy S3, for a few years but I recently started using the Google calendar applications instead on my Galaxy S3.

The issue I'm experiencing is that every time I receive a notification from Google Calendar, the stock application notification also appears. I always get them in double. I tried disabling the notifications in Calendar S but they are set back to enabled automatically. I also tried to remove all my calendars from the stock application but in this case it removed all calendars from the Google Calendar applications as well. It seems that the configurations of both Google Calendar and Calendar S are tied together in some way.

My question is: Is there a way to completely disable the Samsung Calendar S application in order to use Google calendar only as the main calendar application in Android ? My phone is a Galaxy S3 with the latest version of Android installed (4.4.2).
Highest official firmware for Galaxy S3 is up to 4.3. If your phone is running 4.4.2 maybe it's a custom ROM.
Anyway you can disable the calendar storage on the Application-> "All" tab
or just root the phone and remove the S Planner (I believe it's S planner instead of Samsung Calendar S?)
