Lots of updates at the moment I know!
This one’s to provide a workaround for issues some people have been having on Galaxy S and Galaxy Tab devices, where events added on the phone or tablet don’t sync to Google Calendar.
The workaround is a new setting: “Edit in built-in calendar”. Check this and you’ll be able to use the Samsung calendar to add/edit/view events, which means they’ll sync to Google Calendar correctly.
Note: I don’t recommend using this setting for any other devices.
