OPPO phones always pop up advertisements. Where is it closed?

1. If your mobile phone is a non-ColorOS system, when an advertising application is downloaded in the notification bar, press and hold the advertisement to display "Application Information", and then we will know which app is playing the advertisement in the background. At this point, we can turn off the "Show Notifications" option.

2. if your mobile phone is a ColorOS system, please manage application notifications in settings > notification center or notification and status bar.
