Check if Samsung S8 is in full screen mode

Question

Is there a way to check if the device is in full screen mode in the new Samsung S8? I tried solutions added to this post but everything returns true. Detect soft navigation bar availability in android device progmatically?

I can get the correct visibility listening to OnSystemUiVisibilityChangeListener as shown below:

private class MyOnSystemUiVisibilityChangeListener implements View.OnSystemUiVisibilityChangeListener {
    @Override
    public void onSystemUiVisibilityChange(int visibility) {
        if (visibility == View.SYSTEM_UI_FLAG_HIDE_NAVIGATION) {
           // full screen mode
        } else {
           // not full screen mode
        }
    }
}

The above method only works when the user triggers full screen by pressing on the soft navigation button but I need to check if the device is already in full screen mode when it entered the app.

Answer 1

just call on a View View.getSystemUiVisibility() and compare to the same int
