Steps:

1. Find the installed news APP on the phone home page. If multiple news apps are installed, you may need to check them one by one, but the locations are similar. Click to open today's headlines.

2. After entering the homepage of the APP, find the "My" button icon at the lower right and click it.

3. On my personal page, slide up and down to find the settings, and click to enter the settings page.

4. On the Settings page, find the lock screen settings and click Enter. Different apps may use different words, but the meaning is definitely similar.

5. What you see now is that the lock screen is open, that is, the status bar is green, indicating the working state.

6. At this time, just slide the slidable button with the words "Lock screen" to the left. You won't receive any screen lock advertisements unless you open it again in the future.
