Why is there a circle on my screen that keeps going round and round.

[Android Central Question]

When i turn on and go to meetings,l get a circle that continues to go round and i cant get anything else.

that usually means that data is loading... or maybe your calendar data is trying to sync and you don't have a valid data connection or valid credentials? A screenshot would help, too. Or at least which phone and Calendar app are you using.
