I have had an Evo with a Samsung G8 phone and also a Samsung 7" tablet since Dec 2018. VR mode was working correctly with both devices until I recently updated the AE app on my phone only. Now the VR mode gives me a blank screen with the green telemetry data and grid lines. Even when I go back to regular camera mode, the camera view does not return until I restart the app, then it's fine. The tablet, whose AE app I did NOT update, still operates correctly in VR mode. One note- even on my phone, though the VR screen is blank, the camera gimbal still pans down correctly in response to the phone's motion whenever I tilt it.
Another note- I have not updated the firmware in my Evo in the past 6 months. It flies fine so I'm not inclined to update it unless there is a prevailing reason to. Not opposed to it, nor wanting to start a drama, just have had too many Samsung phones that worked great until I allowed their system updates to run.
I'm looking into how I can roll back the app version on my phone to the previous working version. I have no need for the mission planning and other features.
Hope this helps!
