What if the SMS icon of mata8 on Huawei's mobile phone is missing?

Dear, I suggest you try the following methods:

Please confirm whether the application is in the "deactivated" state. I suggest you try to enter Settings > Application Management >;

"Menu"

> "display system",

Find the application in the application list interface and adjust it to "Enable".

If the above methods still can't solve the problem, it is recommended to try to restore Huawei's desktop data (this method will restore the desktop icon sorting and may affect your experience).

Go to settings > application management >;

Select the menu "Display System" and select "Huawei Desktop" >; Storage > just delete the data.
