Android - Navigation Bar replace my Bottom Navigation Bar

_x000D_ _x000D_ The problem is in the title, I use a Bottom Navigation View/Bar, it works fine on smartphone without virtual Navigation Bar : On my Samsung Galaxy S6 Edge without Navigation Bar And with a virtual NavBar, the Bottom Navigation View disappear : On my Huawei with virtual Navigation Bar I tried to remove the Navigation Bar and force the application to go on Fullscreen and the Bottom Navigation View/Bar appeared. It's why I think that the Navigation Bottom Bar is overrided by the Navigation Bar from the smartphone. I want my Navigation Bottom Bar to be above the virtual Navigation Bar! Help me to fix this bug please. EDIT : Here is the layout of this activity :
