Thank you for reporting this.

Using Unity 2017.3.0p1 with the PermissionsDemo scene from Google VR SDK for Unity 1.110.0 I see the following (somewhat different) behavior on a Pixel:

When clicking "request permissions", the user is prompted to remove the phone from the viewer.
If you then rotate the phone to portrait orientation:

• The permissions dialog appears briefly
• The permissions dialog then disappears with an Activity com.google.gvr.permissionsupport.TransitionVRActivity has leaked ServiceConnection message in the device logs
• The permissions dialog is shown a second time
• The user can then "Allow" or "Deny" the permission normally

Here's the full stack trace shown:

Thank you for your reply.
I tried a few times again, and the same situation you've met was found.
But my earliest report of ANR appears after clicking “return to vr”, and the probability of reiteration is not high.
Are these two cases the same problem?
And do you have any suggestions to solve the problem？
Thank you.

Fixed in v1.130.
