It sounds like he "may" be signed in to your device and synced with his contacts and whatever is checked off in the Manage Accounts header on Settings.
Obviously I could be mistaken but from what you've written, I'd provide more information when you author a post, that is what it definitely sounds like.
Was this his old phone? When i grabbed my S22 Ultra and handed down my S21 Ultra to my wife. I was still signed in to that device which meant all of my data was still synced.
I keep signed in to my wife's device because she can use the apps I've installed from the Google Play Store with my account.
I am sure it's either that or my account is logged into on his device which would make his contacts be on my account as well correct?? I'm phone stupid so I don't know noting about them and the 22 ultra is far more smarter then I will ever be am sure.
No I'm sure you've got all the knowledge you need, you've just got to play with the phone and make it YOURS.
He'd have to be physically signed into your device to have his contacts on it. If it was his old device there may be remnants of his data left on it. Even if he used it a few times and signed in it may have then synced with his account.
@mommahass05 It sounds like your husband's account is configured in settings -> Accounts and backup -> Manage accounts. You can remove his account from there.
