How can i determine which account my contacts and pictures on my galaxy s6 are linked to?

[AC Question]

i wish to change the account on at least one of them, but it's not worth it if i will lose my contacts and pictures, galaxy s6 btw

Welcome to Android Central! Open your Contacts app, and select any contact--it should say somewhere what account it's associated with. You might have to edit the contact to see it.

Photos aren't associated with an account, unless you're backing them up somewhere. If you have Google Photos Auto Backup turned on, then they would backup to the primary Google account on the phone.
