Why didn't my R9s receive text messages and music tips?

Why didn't my R9s receive the text message but didn't prompt the music? It is recommended to enter the phone settings-sound and vibration, turn off the mute mode and turn on the ringtone mode. Enter the phone settings-do not disturb, and turn off the do not disturb mode; Enter Settings-Notification and Status Bar-Notification Management-Information, and turn on ringtone notification; After backing up the data files in the mobile phone, restore the mobile phone to the factory settings. After the above attempts, the problem still exists. You can take your mobile phone to the customer service center for free testing. You can quickly find the address and telephone number of OPPO Customer Service Center in the following ways:

1. Enter the OPPO official website-Service-Service Network for inquiry; 2. Enter OPPO+- Home-Recommendation-Customer Service-Service Network.
