Hi, suggested solution does not work. My problem is perhaps slightly different? Preinstalled calendar only syncs the default Google calendar (gmail account), no other calendars. When I press update, and every now and then in between, I get error message "Google calendar sync has stopped", which probably is why only the first (default) calendar is synced to the phone. Note: I have the same calendar problems on three (3) Sony phones: M2 Aqua, Z1 and Z3. Have downloaded standard Google calendar app to Z3 from Google play, no difference. Calendar works fine in two Samsung mobiles, web UI and two desktop clients (emClient and Lotus Notes/AWESync). The fact that it doesn't work in any of my three Sony phones but works just fine everywhere else is rather disturbing, wouldn't you say? If I were Sony, I'd fix it pretty fast if I wanted to sell any phones.
