Wifi has always been mobile in China. Can't the information advertisement on the drinking network be closed?

If you want to continue using the wifi master key, you can't turn off the lock screen advertisement. Advertisements are built-in and can only be closed after uninstalling.

If your mobile phone often pops up some advertisements, it must be caused by some software installed in your mobile phone running in the background and then popping up advertisements, so you can find some related software to uninstall it, which will often solve this problem. If it still can't be solved, I suggest you directly restore your mobile phone to the factory settings. Of course, before restoring the factory settings, you should back up all the important data on your mobile phone to your computer, which can completely solve this problem.
