Galaxy S2 Android 4.1.2 - calendar sync option disappeared I just upgraded my SGS2 to 4.1.2 and I have huge problems synchronizing my Google calendar. 

First of all, my Google calendar app disappeared. Until here ok, I reinstalled it from Google Play. When I try to add my google calendar accounts, they are just not there.

I try in Settings&rarr;Accounts&rarr;Google and choose my Google account to see the sync options inside. The option "Sync Calendar" does not exist anymore.

Did anyone have this problem? How did you solve it?
i just found out that there was one process - CALENDAR STORAGE - which was disabled. I enabled it, and then i could see the option SyncCalendar in my google account again. 

after that my calendar is working fine again.
