S8+ running android 7.0 Status and Navigation Bar Issue In VR Scene

Hi,
I have a cardboard vr app which loads vr screen but first there are some 2d scenes for login signup etc and once you are in the app you can go into the vr mode. Everything is working fine but i found a issue recently that when i open the app and swipe down/up the status bar and navigation bar show up fine but after i load vr mode and then exit vr mode to get back to 2D scene then swiping up and down don't show the navigation and status bar for the device hence i cannot use the back button which is very annoying. Since the status bar also don't show up by swiping down if i get any message or call it also didn't notify me in status bar when app is running.
Any help ?
Thanks

 

Have you find a solution yet ?
I think another devices (except S8) maybe work perfectly
