We need a lot more info to help you out:
- What phone/tablet/device is this?
- What carrier?
- What version of Android were you on prior to Android 5.0 and what method did you use to update it?
- Can you share screenshots?
- Why do you need to create a Google Account, shouldn't you just be signing on with the account you used prior to the upgrade?

Because it's white there. But if you don't believe me, you can find a lot of pictures and videos on the internet.
