How can I unlock my S7 Edge without the pattern?

[Make Fuutje]

My sister put a pattern lock on my mothers s7 edge, and she doesn't know the pattern anymore. How can I remove this without resetting?

- USB Debugging is not turned on.
- Phone is not rooted (And I don't want to root it because it could **** the phone up.
- No Google nor Samsung account.

Any idea how I can fix this?

Edit:
Don't know how to add comments, but thanks I guess.
I'll just go to the store where I bought it hope they'll help me.

Welcome to Android Central! Sorry, but you're stuck. Your main option would have been to use Samsung's Find My Mobile, but since there's no Samsung account, I don't think you'll be able to use it. https://findmymobile.samsung.com/
