Correct pattern lock it shows incorrect pattern

Hey buddy, you can backup to external drives like to a computer or simply backup to samsung Cloud. Most times if you have enabled automatic backup in samsung acc that'll do. Or specially for contacts you can also backup to google acc. But photos videos and apps will be all deleted.

Make sure you have the purchase invoice or receipt as this is related to security you might need to verify your identity for security reasons.
