If the pattern/signature unlocking mode is set, it can be unlocked by using the PIN code set when drawing the unlocking pattern/signature. Operation:

1) Enter the incorrect unlocking pattern five times, and a prompt message will be displayed on the screen. Please try again after 30 seconds and click OK. Click the 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 the wrong signature for five times, a prompt for entering the PIN code will appear on the screen. Enter the previously set PIN, and then click OK.

Tip: The PIN code prompted when unlocking is the backup password set when you set the pattern lock.

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

Precautions for setting mobile phone password:

1. Don't make the password and account name the same. The password and account name are the same, which is a big taboo for setting passwords. Many people may set the password and account name the same for convenience, so as to facilitate memory.

2. Don't use part of your mobile phone number, account number or ID card as your password. Commonly used are mobile phone number, account number and ID number. If these numbers are set as passwords, it is easy for people to think of these numbers and it is very likely that others will crack the password.

3. Don't use regular characters and numbers as passwords. Regular characters and numbers, such as birthday, consecutive numbers, consecutive letters, etc. , are easy to be seen by others, so you must not use these conventional characters and numbers that you think are easy to remember as passwords.
