Why is oppo r9 not prompted when it receives new information with nails?

Hello, when using nailing software on OPPO mobile phone, you need to turn on the nailing background to run the application and several other settings to hear the nail tips and sounds. The main reason is that the mobile phone system automatically cleans up the software running in the background after the black screen is on standby. The solution is as follows:

1, Settings-Battery-Nail Finding-Turn off "Background Freeze" and turn off "Automatically optimize when abnormality is detected"

2. Automatic startup operation steps: mobile phone housekeeper-right privacy-self-startup management-find nail switch.

3. Notification setting operation steps: Settings-Notification and status bar-Notification management-Find nails-Turn on all options.

4. Multi-tasking interface locking operation steps: the function key in the lower left corner of the mobile phone-find the nail-drag the nail to slide down.

How does OPPO R9 open the notification bar to display information notifications?

Drop down the notification bar and click Notification Management.

Select a software that you don't want to miss information, and check it.

Grant software notification rights.

For example, choose a music player software, such as opening Netease Cloud Music and playing a favorite song. At this point, you can see that the song playing information is successfully displayed on the notification bar.
