How to unlock screen of found lost Samsung S8

[Android Central Question]

Hi,
Can anyone help me how to unlock my phone using Find My Device. It was lost but i already found my found. I locked it during it lost. Now the phone is with me I'm trying to enter my passcode but it keep on saying wrong passcode which i am very sure.

Please help me. As i don't want to reset it coz all files in my phone are important especially the photo of my students.

Thanks,
Josette

Use Android Device Manager to change the passcode, wait 24 hours, then try it.
