Can't unlock my old unused phone

[Old Man Jak]

So, I've got an old unused phone. Disconnected and everything. Still has my pictures and such on it and I can't remember my pin to unlock it. It is an old straight talk phone. Does anyone have any idea on how to get through the pin without a factory reset?

If it's running an old operating system like Android 4 and down, then try putting in a code a bunch of times till it allows you to put in your Google account info and that will open your phone. Otherwise i don't know of a way
