Why doesn't the screen light up when my mobile phone comes to WeChat message?

WeChat does not enable message notification authority, specifically, it does not enable message notification when the screen is locked.

There is something wrong with the mobile phone itself. The mobile phone receives some messages, but the screen is not bright and there is no new message reminder.

The following are the specific methods and steps for OPPOR9m to open WeChat message notification in lock screen mode:
