This crash no longer occurs in 4.14.
Projects using Open Level (blueprints) or ServerTravel (in C++) will crash the application once it's open on a device using Gear VR Mode.

1. Download Project here: [Link Removed]
2. Unzip and Open project in 4.13.1-3142249
3. Verify the project settings are set up for GearVR: https://docs.unrealengine.com/latest/INT/Platforms/GearVR/QuickStart/index.html
4. Package for Android
5. Install APK on S6 or S7 for GearVR
Result: The game will crash after 5 to 10 seconds (there is a delay on the open level blueprint)
Expected Result: The open level should work without crashing the application on the device.
