If you forget the screen lock password of Samsung mobile phone, you are advised to refer to the following contents:

1. If the pattern/signature unlocking mode is set, you can use the PIN code set when drawing the unlocking pattern/signature to unlock it. Operation:

1). Enter the incorrect unlocking pattern five times, and the prompt message "Please try again after 3 seconds" will be displayed on the screen, and click "OK". Click "Backup PIN" in the lower right corner of the screen, enter the previously set PIN password, and click OK.

2). If it is a signature unlocking method, after entering an incorrect signature for five times, a prompt for entering a PIN code will appear on the screen. Enter the previously set PIN code and click OK.

prompt: the PIN prompt when unlocking is the backup password you set when setting pattern locking.

if it is invalid, the backup PIN password is forgotten or does not meet the above requirements, please send the machine to Samsung service center, and the after-sales engineer will help you unlock it safely.
