What happened to Samsung s2 1ultra's interest screen? After half an hour, I couldn't get the information from WeChat connected to WiFi.

First, click Settings to enter in the mobile phone program interface, and then click WiFi to enter WiFi. We find the option to manage the application, enter the application WiFi interface, and click on the three points in the upper right corner.

Click the pop-up option of restricting background WiFi, and then click the interface of freely using WiFi to freely use WiFi traffic, and turn on the switch behind WeChat.

Settings-Sounds and notifications-Lock the notifications displayed on the screen-Show content/Hide content/Don't show notifications-Just select the display content.
