title: Navigation bar overlaps with bottom bar icons
body: <p>I am Android developer and dealing with Android Nougat (7.0) source code. I experienced kind of strange problem in Snapchat app. In the app, bottom bar icons overlap with the android navigation bar, so I can't use bottom bar icons in the app. I found this issue from different resources as well so I am confused whether this problem is in the app side or in the code base. Does anyone have any idea what can cause this problem?</p>
