Galaxy s3 how to remember the google account it is tied to?

[Jesscee]

So I happened to find my old galaxy s 3 but for some reason I cannot for the life of me remember what google account it was connected to. It doesn't give me the option to do any alternative sign in options like these newer phones. It only let's me use my email and password or pin number. I have used every email I can think of every 6 digit number I can think of and no success with logging in. Any one have any suggestions on how I can find out what Google account is connected to this phone ? I'm not trying to reset the phone entirely as I am trying to get the photos off this phone.

Did you, by chance, try the forgot username option?

There is no forget username option unfortunately

Just curious, what are you going to do with a 10-year-old phone if you can get into it? It probably only has 2 gig of ram, and up to a whopping 64 gig of hard drive. Plus, it is had no OS updates or security updates in years.

I don't want or care about the phone at all . Probably gonna let my kid play with it. I just want all the pictures on the phone.

This is what I have to work with
