Need so help. Last night I was putting a lot of info into my Calender and today when I powered it up it just freezes up and ( The application Calender Storage (process com.android.providers.calender) has stopped unexpectedly. And the tab wont let me do anything. So tried a hard reset by holding the power button and the volume down and when I doe that I get yellow triangle saying download wait. But its never resets. What can I do?
