I've always used the default calendar app on my note 3, guessing its the Samsung calendar app. I decided to give Google Calendar a try and installed it but I kept getting vibrating notifications for my events even after turning the setting off. Apparently google calendar synced all my events to that app also. I uninstalled google calendar but then when I reverted to using my default calendar app (Samsung calendar) all my events are now gone. I tried reinstalling google calendar again but that didn't work. Is there a way to recover all my deleted events/tasks? Please help.
