When I use the quick event insertion (touch on a day in the calendar) and change the time, duration, or repeat it moves the date back one day. For example, I touch "25" on the calendar and touch the "+" to create an event. When I press the "Duration" button and set a duration the date is now the 24th. When I press on the "Time" button and set a time the date changes to the 23rd. None of this happens if I use the stock calendar app to add an event. I've emailed the developer and he can't figure it out. His solution is to just use the stock calendar to add events. That's not a solution. Does anyone else have this problem? Maybe if it's shown to be a problem on all Droid Xs he'll get one and fix it.
