There is a beep on the phone, but I can't see any information.

Does the subject want to ask, "Why can't I see any information when the phone has a beep?" Ring permission notification is not turned off, and automatic reminder, system upgrade reason and SMS interception are set.

1. If "Ring or Allow Notification" is not turned off, you can go to the notification bar and status bar in the settings, check the notification management, find the software that sends the notification, and turn off "Ring or Allow Notification".

2. The software is set with automatic reminder, and sometimes the network is disconnected and then resumed, and some software will make a sound.

3. This will happen after the system is upgraded.

4. When the short message is intercepted, there will be a prompt tone, but no message will be displayed. You can turn on the settings, check the auxiliary functions, and turn off unnecessary message prompts.
