If the password set on your phone is a pattern/signature unlocking method, use the PIN code set when drawing the unlocking pattern/signature to unlock. If you forget it, do this:

1. First If you enter incorrect unlock pattern five times on the phone screen, a prompt message please try again in 30 seconds will be displayed on the screen, and then click OK. Then click Backup PIN (forgot password) in the lower right corner of the screen, enter the PIN password you set previously, and click OK.

2. If the setting is the signature unlocking method, after entering five incorrect signatures, the screen will prompt you to enter the PIN code. Enter the PIN password you set before, and finally click OK.
