Recently the stock calendar app on my Intercept stopped working properly. I first noticed it when the non-stock calendar widget I use (Pure Calendar) suddenly was empty of all events. When I went into the stock app, it was empty too. But all my events and calendars are still intact on Google Calendar (web). Now every time I go to the Calendar app settings, and click on "Calendars", I get the "process com.android.calendar has stopped unexpectedly" error message with a force close button. If I try to create a new event on my phone, it goes through the motions but the event is not saved. If I click on "Calendar" in the new event screen, I am presented with an empty list for a screen, and then the "process com.android.calendar has stopped unexpectedly" error appears when I press either Save or Cancel. I have tried solutions I found in other forums to no avail. I have tried clearing data from the Calendar app; that didn't help. Oddly, "Calendar Storage" doesn't appear in Manage Applications, only "com.android.providers.calendar" which I understand is the calendar storage but it appears very corrupted. Storage is listed as "0.00B" and there's no Clear Data choice, just "Uninstall". I'm guessing that's the root cause of my problem but I have no idea how to fix it. If it's corrupted, will a Factory Reset be able to fix it?
