5.6.1f1 : Android app thinks it's supposed to be GearVR when it's not VR at all

I am building an app for android. When launching the app on the device, it gives me the "insert your device into your Gear VR" screen

However, my "Virtual Reality supported" checkbox in the Player Settings is clearly disabled. I've tried every possible combination of deleting Library folder, restarting Unity, changing the app/package name, uninstalling the app, restarting the phone, restarting the app, etc, etc... and it STILL thinks it's supposed to be a Gear VR app. The app was previously built for GearVR on that device, but now it's not supposed to be VR anymore.

How to I fix this?

 

Root cause is going to be your manifest has the gear vr entry in it. If you have the Oculus Utilities installed that is likely whats causing it but you'll have to investigate. Based on that submit a bug report to either Unity or Oculus depending on who is the culprit.

 

I have the same problem.
My app is NOT VR and has never been, it has been working fine for a year.
Today, I upgraded Unity 5.3 to 5.5 and now the app thinks it is VR.

How did you fix it?
