Why is the screen not bright when Meizu mobile phone comes to WeChat message?

In this case, in the "Settings" interface, click "Notification Bar and Status Bar-Notification Center", find WeChat, and start the "Allow Notification" function. At the same time, you should also turn on the message notification function that comes with WeChat. If under the theme of "Magazine Lock Screen", you can't perform "Notification Highlight" and "Display Notification Details" unless the screen is locked, these two options can be found in the options under the "Settings-Screen Lock and Password" interface (only when setting "Magazine Lock Screen"). You also need to set -WLAN- menu-advanced settings-so that WLAN connection selection is always dormant.
