I am using samsung galaxy fame duos (s-6812). I was using google calendar app to show the contacts birthdays and it was working fine. When I rooted my phone and deleted my system calender app and s planner app, google calendar stopped syncing contact birthdays and shows message "No calendar selected to be synchronized". When I try to change setting and try to add "Event from Gmail" or I refresh it, phone hanged and it again rebooted. Please tell me how to make google calendar app independent of system calender app. Tell me if I need to download any other apk for this..??
