How to stop image rotating right when I look down in Google Cardboard project?

I’m just testing the Cardboard SDK - I’ve built a couple of small test scenes, installed and run from my Android phone, but in both cases when I look down the image rotates to the right.
Has anyone experienced this?
I wonder if this is because I altered the position of the camera from the original scene demo position?
Any help very much appreciated - maybe a simple fix but I’m new.

I’ve never played around with Google Cardboard, but I’m guessing that when you are moving your head around, it’s rotating the screen orientation. You need to go to your project settings and force it to stay in landscape mode, not auto orientation.

If you are using the prefab called CardboardMain, make sure not to move the Main Camera child object – I don’t know if that’s your exact bug, but it could easily cause that. Move CardboardMain itself.

Thanks both - dolims - that’s fixed it, many thanks.

Hi… Can Any one help me plz… I am new to Unity… i have made a VR app for MRI Simulation… the problem is my Cardboard SDK is working fine but when inside VR if i keep my head still the camera itself moves slowly to any direction… i mean if i am not moving … my camera should stay on one point rather than move… any one???

I am using GVRMain

does it happen with the GVR sample scenes also, or only in your scene?

ps. that could also be gyroscope drifting,
in that case, search for: calibrate gyroscope android
(that fixed drifting for a brand new samsung s4 phone for me…)
