How to unlock Pin password my sumsung J7?

[AC Question]

A few days ago my Sumsung J7 phone is locked after updating new software version. I am sure that I put correct pin password but I can't enter home screen. Try again 10 mins later or try again 60 mins later like that. How can I solve this problem? I don't want to lose my data in my phone.

Try a Cache Partition wipe. Also, you may be able to reset your PIN via Android Device Manager, or the Samsung equivalent.
