We're currently in the process of upgrading our project. We are using the Oculus VR Rift SDK Version 3.4.1 with unity 2017.2.0p1 where the controller back button worked like expected. However, with Oculus Utilities SDK Version 1.31 and unity 2018.4.0f1 the application just quits when pressing the back button. This is without any of our code using the OVRInput class. It's also not just going to the home leaving the application alive, it actually quits. I don't see it crashing in the logcat either.
