I'm sure a lot of people here are familiar with Android, so hopefully someone will provide some insight. This is pretty basic because I know nothing about Android.

I'm thinking about getting a new phone and am browsing the user manuals for a few models. It seems that google and its various functions are inextricably integrated into the operation of the phone.

Is it even possible to own and use an Android phone without signing into a google account? If so, how often is the phone going to prompt you to login to a google account, and how much of the phone's functionality is unavailable if you're not signed into a google account?

Thanks!
