Android Question Application icon

[AlfaizDev]

My app icon appears in some places on mobile

While you find it elsewhere, it doesn't show up.
It shows the virtual icon of the programming language.

I'm having this problem in all my apps.

This happens when you installed an older version of your app without a custom icon. Restarting your phone should fix it.

Correct
I've tried it now.
When adjusting a custom icon for the application before installing the program for the first time
It works.
Thank you

Restarting your phone should fix it.

It hasn't worked yet.
Is there another way to permanently clear the app from mobile?
To come back.
