When Apple's mobile phone QQ locks the screen, a message prompts twice. How to solve it?

It should be a bug in the software system. I suggest restarting it, and it should be all right.

What should I do if the screen automatically pops up when QQ locks the screen?

1. Click the QQ icon to open QQ;

2. After opening the QQ page, hold down the screen and slide to the right;

3. The QQ Settings page appears, and click "Settings" in the lower left corner;

4. On the new page, click "Message Notification";

5. Find the "Lock Screen Display Message Box", see that the drag bar on the right side of this column is green, and slide this drag bar to the left;

6. At this time, the drag bar on the right side of "Lock Screen Display Message Bullet" turns white, and the setting is finished;

7. After locking the screen again, QQ messages will not pop up automatically on the screen.
