With the release of Android 6.0 (Marshmallow), there came runtime permissions which behave a bit more like the permission system on iOS. Unfortunately, this was causing a crash for some users on Android 6.0 when they were prompted for permissions. We apologize for any inconvenience and have released an update which resolves this issue. We recommend any user who experienced this to download the update through the Oculus GearVR Store. Again, we apologize for any inconvenience and will do all we can to prevent issues like this in the future.
