I am having problems with the calendar on my phone. I enter events and they disappear. I have been to a store 3 times, swapped out a phone, been on tech support and no one can seem to fix this. The calendar/phone is synced to my gmail account. Sometimes events stay on the calendar but many disappear within minutes. Any one else having this problem or have any ideas. I was told by one store sales person to go to the app store and pick out another calendar. There are over 2000 to choice from. Why should I have to go through over 2000 calendars because the one that came with the phone does not work?
