Description

You can disable S Planner in systemsettings in Android 5.0 Lollipop, this app is not neededanymore if you have Lollipop. Follow instructions in thescreenshots to disable it.

If you don't have this option in system settings, get adbcommand from Android developer tools, plug your phone into PC,enable USB debugging in Android settings, and run this command onyour PC:

adb shell pm hide com.android.calendar

If nothing helped, you can try installing this app, but this isnot recommended, as it works only 50% of time.

This app will hide all notifications from Samsung S Plannercalendar, so you can use another calendar app without having allyour notifications duplicated.

It starts at boot, and runs in background, so you only need tolaunch it once, and enable it in Notification Access systemdialog.

S Planner cannot be turned off in any other way without rootingin Android 4.4 or older - disabling notifications in S Plannersettings will be reverted after reboot, de-selecting calendars willdisable them for all your calendar apps, it cannot be turned off inApplication manager, and clearing it's data won't help either.
