So has Samsung Gio with Android 2.3.3. Problem: gmail filled in the field "birthday" filled with the year of birth, for example, 01.01.1981 (gmail), Google calendar account, added calendar "birthdays and events of contacts" in the calendar settings set to show both calendar — the birthdays of contacts are not displayed neither on the computer nor on the phone. And for some strange reason one's birthday appeared to Akka, synchronized, appeared on the phone and alerted. Then was established the contact with the occasion. Sync — neither there nor there anything. Now it's all ruined, i.e. do not appear anywhere else.
Tried to unsubscribe calendar "birthdays and events of contacts" and add it again. Silence. Not appear. Do not expect such "miracles". I have a Sony Z550i, everything was just great, and then a full OS and the silence.
Question: prompt, who knows/experienced how to make birthdays automatically added to your calendar account (sync and reminders are excellent) or maybe separate. (even paid), which automatically pulls birthdays from your contact book and will remind when it is necessary.
