The phone is locked. How to solve a string of symbols and a key pattern?

You can clear the phone's power-on lock screen password in the following three ways:

1, it would be much easier if the phone had turned on USB mode before. Just download a brush wizard from the computer, connect the mobile phone after turning it on, and select Clear Lock Screen on the right. If USB mode is not turned on, look at the following two;

2. The computer downloads an adb toolkit, decompresses it, puts it in the root directory of computer disk C, and connects it to the mobile phone. The connection here means that you don't need to turn on USB mode, as long as the phone shows that it is charging after connection. After that, open adb and choose to delete the file named *. Key to clear the screen lock password.

3. When the mobile phone is turned off, press and hold the Volume Up button+Dial button (green)+Power button to resume. In the recovery mode, press the Volume Up button to move to Erase Data/Restore Factory Settings, press the power button to confirm, then select Yes-Erase all data, press the power button to confirm, and finally choose to restart the system now, press the power button to confirm, and then wait for the phone to restart. However, this method has a drawback, that is, it will clear the data on the mobile phone.
