Why can't 7plus open a national anti-fraud center?

You can use the Apple system of the National Anti-Fraud Center. If it doesn't work, the version installation package may be damaged or you don't have permission to open it. If the installation package is damaged in the first case, just download another one directly. If it is the second reason, if there is no open permission, the specific operation is as follows:

Enter the main interface of the national anti-fraud center APP, and click the "fraud warning" icon;

In the "Fraud Alert" interface, click the "Open Now" button below;

Click "Go Now" at the bottom of the permission pop-up window to open the floating box;

Find the National Anti-Fraud Center in the application list, click Enter, and the upper switch displayed in other applications will be turned on, and then exit.
