Google VR on Samsung Galaxy S7 distorted

Hey guys,
When launching my app on my Samsung Galaxy S7 phone the view is oddly stretched and the middle point is no longer in the center. It’s getting better when changing the resolution on the phone directly. No problem on the Samsung S6. How can I fix it?

I’m having the same issue. I tried apps from the google store and they work fine. But when I run my app I go cross eyed.

I finally found the issue! my Samsung s7 was set to 1080p instead of the full 1440p of the screen. Switching it fixed the problem!

Yes, thanks. Meanwhile I found out the same. But as the app is meant for the play store, how can I prevent this issue on other users phones?
