How to make Redmi 7 mobile phone always display the application icon at the top when sending messages?

What kind of mobile phone are you? Your icon cannot be displayed. Let's see if there is a program corresponding to the menu, or you can open it and try it. Initially, it is judged that your application is installed on the memory card, and you have moved the memory card, so just turn off the memory and wait for it to refresh when booting, and there may be some machine cards that display slowly! I hope the answer is satisfactory!
